In the complex environment of industrial production, the cleaning of pollutants such as dust and debris is crucial. As an efficient cleaning equipment, the single-phase double-barrel bag industrial vacuum cleaner is playing an increasingly important role.
What is a single-phase double-barrel bagged industrial vacuum cleaner?
· Basic definition: Single-phase double-barrel bag industrial vacuum cleaner is a specific type of industrial vacuum cleaner. It is driven by a single-phase power supply, has two dust collecting barrels, and uses a cloth bag as the core filtering component.
· Function: It can adapt to the cleaning needs of various industrial scenarios, and can effectively collect various dust, debris and other pollutants generated in the industrial production process, prevent them from spreading into the air, and ensure a clean working environment and the health of personnel.
· Structural advantages: The double-drum structure enables it to have a larger dust collection capacity and stronger continuous working ability, which can meet high-intensity industrial cleaning tasks.
What is the working principle of a single-phase double-barrel bag industrial vacuum cleaner?
· Negative pressure vacuuming: After the equipment is started, the single-phase motor drives the fan to rotate at high speed, creating a strong negative pressure environment inside the vacuum cleaner. Under the effect of this negative pressure, the dusty air from the outside will be quickly sucked into the vacuum cleaner through the suction nozzle. After the dusty air enters, it first reaches the first dust collection barrel. At this time, the larger particles of dust will initially settle and separate in the barrel due to their own gravity and changes in air flow speed, completing the initial filtration.
· Bag filtration: After the initial filtration, the air will carry smaller dust particles into the bag filtration area. The bag is made of special fiber material, and the tiny pores between the fibers can intercept dust. When the air passes through the filter bag, the dust is blocked on the surface of the filter bag, and the purified air passes through the bag and continues to be discharged out of the vacuum cleaner through the fan. As the filtration process continues, the dust on the surface of the filter bag will gradually accumulate. When the accumulation reaches a certain level and affects the suction, the bag needs to be cleaned through the dust cleaning device to restore its filtration performance and ensure the continuous and efficient operation of the vacuum cleaner.
What are the classification methods of single-phase double-barrel bag industrial vacuum cleaners?
· Classification by cleaning method
1. Manual dust shaking:The dust attached to the filter bag is removed by manually operating the dust shaking device, such as shaking the dust shaking rod. This method is simple to operate and has low cost, but the cleaning effect is relatively limited and it relies on frequent manual operations. It is suitable for scenes with small dust volume and simple working conditions.
2. Automatic pulse cleaning:compressed air is used to pass through the pulse valve to spray high-pressure gas into the filter bag in a very short time (usually 0.1-0.2 seconds), causing the filter bag to expand and contract instantly, thereby shaking off the dust on the surface. This method has good cleaning effect, high degree of automation, and can achieve continuous operation. It is suitable for industrial environments with high dust concentration and strict filtering requirements, such as metal processing, mining and other industries.
· By mobility
1. Fixed type:This type of vacuum cleaner is usually installed in a fixed position, and each vacuum point is connected by a pipe. Its advantages are strong vacuuming ability and long-term stable operation. It is suitable for places with centralized and fixed vacuuming needs such as large factory workshops. The disadvantages are high installation cost and poor flexibility. Once the installation location is determined, it is difficult to change it later.
2. Mobile:Equipped with rollers and other mobile devices, it is convenient to move between different work areas. Its dust collection capacity is relatively small, but it is highly maneuverable and can adjust the dust collection position at any time according to work needs. It is often used in small factories, temporary work sites, or work scenes that require frequent changes in dust collection locations, such as construction and decoration sites.
What are the characteristics of a single-phase double-barrel bag industrial vacuum cleaner?
· Powerful and stable vacuuming ability
The double-barrel structure of this vacuum cleaner provides it with ample dust collection space. Compared with the single-barrel design, it can accommodate more dust and debris, reducing the trouble of frequent dumping of collected dust, and can meet the needs of long-term continuous operation. At the same time, the high-power single-phase motor is powerful and can generate strong and stable suction. Whether it is metal debris scattered on a large area on the ground, or fine dust deposited on the surface of equipment and in narrow gaps, it can quickly absorb it. In the machining workshop, heavier iron filings, aluminum filings, etc. can also be easily sucked into the dust collection barrel under its powerful suction. The characteristics of efficient cleaning greatly improve the cleaning efficiency of the industrial environment.
· Excellent and efficient filtration performance
Using cloth bags as the core filter medium is a highlight of single-phase double-barrel bag industrial vacuum cleaners. These bags are made of special fiber materials through advanced weaving technology. The fine pores between the fibers are like a precision filter, which has an excellent interception effect on fine dust. After professional testing, it can filter out micron-level dust particles with a filtration efficiency of more than 99%. In the woodworking workshop, wood dust that is easily dispersed, or harmful chemical dust that may exist in chemical production, can be firmly blocked on the surface of the filter bag, ensuring that the exhausted air meets or even exceeds environmental protection standards. This not only reduces pollution to the environment, but also creates a clean and safe breathing environment for workers, effectively reducing occupational health risks.
· Outstanding durability and reliability
The industrial production environment is often harsh, and factors such as dust, vibration, and high temperature place strict demands on the durability of equipment. Single-phase double-barrel bag industrial vacuum cleaners are very particular about material selection. The body is mostly made of sturdy and durable metal materials, such as stainless steel, or high-strength plastic, which has strong resistance to wear and corrosion. Its key components such as motors and fans have undergone special design and strict manufacturing processes and have a high level of protection. During long-term continuous operation, it can operate stably even in an environment with high dust concentration or facing a certain degree of vibration, greatly reducing the occurrence rate of equipment failure. This not only extends the service life of the equipment, but also significantly reduces the company's cost investment in equipment maintenance, repair and replacement.
· Easy to operate and safe
In terms of operation, the vacuum cleaner fully considers the needs of workers in industrial scenarios and designs a simple and intuitive operation interface. Usually, it only requires simple operation of the start and stop buttons, as well as the knob to adjust the suction power. Workers can quickly get started and operate proficiently without complex training. In terms of safety performance, it is equipped with multiple protection devices. The overheating protection function can be automatically triggered when the motor temperature is too high to avoid safety accidents such as fire caused by overheating; the leakage protection device can quickly cut off the power supply when the equipment leaks electricity to ensure the personal safety of the operator. In addition, the overall structural design of the equipment also fully considers stability and safety to prevent injuries caused by accidents such as tipping and collision during use, and comprehensively ensure the safety of personnel and equipment.
In what fields are single-phase double-barrel bag industrial vacuum cleaners used?
Mechanical processing industry
In the mechanical processing industry, such as automobile parts manufacturing, aerospace parts processing, etc., turning, milling, grinding and other processing processes will generate a large amount of metal debris and fine dust. If these debris and dust are not cleaned up in time, on the one hand, they will be scattered on the guide rails, lead screws and other key parts of the processing equipment, accelerating equipment wear, affecting processing accuracy and equipment life; on the other hand, metal dust accumulates in the air, and there is a risk of explosion when it reaches a certain concentration.
The single-phase double-barrel bag industrial vacuum cleaner can timely and efficiently remove metal debris such as iron and aluminum chips generated during the processing process, as well as fine metal dust generated by grinding, by setting up a special suction port next to the processing equipment. Its powerful suction can quickly suck heavier metal particles into the dust collection cylinder, and the efficient bag filter system can effectively intercept micron-level metal dust with a filtration efficiency of more than 99%, preventing metal dust from spreading into the workshop air, which not only protects the respiratory health of workers, but also reduces safety hazards, maintains a clean production environment in the workshop, and ensures the stable operation of precision processing equipment.
Woodworking Industry
The woodworking industry generates a lot of sawdust and wood dust during the production process of wood cutting, grinding, carving, etc. The accumulation of sawdust not only affects the cleanliness of the workshop, but also may hinder workers' operations and reduce production efficiency; and wood dust is a flammable and explosive substance. When it reaches a certain concentration in the air, it is very easy to cause an explosion accident when encountering a fire source, which seriously threatens the production safety of the workshop. In addition, long-term inhalation of wood dust will damage the respiratory system of workers and cause occupational diseases such as pneumoconiosis.
Single-phase double-barrel bag industrial vacuum cleaners can effectively solve these problems. Installing a vacuum duct on wood processing equipment and connecting it to the vacuum cleaner can timely remove wood chips and wood dust generated during cutting and grinding. Its large-capacity double-barrel dust collection structure reduces the frequency of cleaning and can meet the needs of continuous operation in woodworking workshops. At the same time, the efficient filtration system can intercept wood dust on the surface of the filter bag, and the purified air emissions meet environmental protection standards, which not only keeps the workshop air clean, but also eliminates the risk of explosion, creating a safe and healthy working environment for the woodworking workshop.
Chemical Industry
During the chemical production process, various chemical dusts, particles and fumes with corrosive, toxic or flammable and explosive properties are generated. For example, dust containing organic solvents is generated in paint production, and toxic chemical dust is generated in pesticide production. If these pollutants are not handled properly, they will not only cause serious harm to the health of workers, but also pollute the surrounding environment and violate environmental protection regulations.
In response to the special needs of the chemical industry, single-phase double-barrel bag industrial vacuum cleaners can use corrosion-resistant materials to make the body and filter components, such as stainless steel dust collection barrels and specially treated corrosion-resistant filter bags. Its good sealing performance can effectively prevent the leakage of harmful chemicals. Setting dust collection points in the reactor, drying equipment, packaging machines and other locations in the chemical workshop can timely collect various chemical pollutants generated during the production process. Through an efficient filtration system, harmful dust is intercepted in the filter bag to prevent it from being discharged into the atmosphere, meeting the strict environmental protection requirements of the chemical industry and ensuring the safety and environmental protection of the production process.
Food Industry
The food industry has extremely high requirements for the cleanliness of the production environment. Any dust or foreign matter may cause food contamination, affecting product quality and food safety. In the process of flour processing, baked food production, candy manufacturing, etc., flour, powdered sugar, crumbs and other dusts will be generated. These dusts will not only affect the workshop environment, but also may adhere to the surface of food, causing the product to be unqualified.
The single-phase double-barrel bag industrial vacuum cleaner adopts filter materials and sealing design that meet food hygiene standards, avoiding the risk of secondary contamination. Installing this vacuum cleaner at the feeding port and packaging link of the food production line, where dust is easily generated, can timely remove scattered dust and debris. It is easy to operate and convenient for cleaning operations during food production intervals without interfering with the food production process. At the same time, the efficient filtration system can effectively purify the air, maintain the cleanliness of the food production workshop, ensure that the food is not contaminated during the production process, and ensure food safety.
What is the production process of single-phase double-barrel bag industrial vacuum cleaner?
Parts Manufacturing
1. Dust collector manufacturing: Choose metal plates (such as stainless steel plates) of appropriate thickness or high-strength plastic particles. For metal dust collectors, use cutting equipment to cut the plates into the required shape, then use a plate rolling machine to roll them into a cylinder, and then use welding technology to firmly weld the joints to ensure the sealing of the cylinder. After welding, the cylinder is ground, polished and other surface treatments to improve its corrosion resistance and aesthetics. For plastic dust collectors, the injection molding process is used. The plastic particles are heated and melted and then injected into the mold cavity. After cooling and molding, they are demolded to obtain the dust collector blank, and then necessary trimming and processing are performed.
2. Motor manufacturing: As the core power component of the vacuum cleaner, the motor has strict manufacturing process requirements. First, in the winding workshop, the enameled wire is wound on the iron core of the motor stator and rotor according to a specific number of turns and winding method to ensure that the electromagnetic performance meets the design requirements. Then, the iron core is stamped to ensure the dimensional accuracy and magnetic permeability of the iron core. After completing the winding and core assembly, the motor is insulated to prevent electrical faults such as short circuits. Finally, the motor is tested for performance, including speed, torque, current and other parameter tests to ensure stable and reliable motor performance.
3. Bag production: According to the filtering requirements of the vacuum cleaner, select appropriate fiber materials, such as polyester fiber, aramid fiber, etc. The fiber is made into a filter cloth with a specific pore size and strength through a textile process, and then the filter cloth is sewn into a filter bag using a sewing machine according to the design shape of the filter bag. During the sewing process, ensure the firmness and sealing of the seams to prevent dust leakage. Some high-end filter bags will also be coated on the surface to further improve the filtering accuracy.
Overall assembly
1. Component pre-installation: Preliminary pre-installation of manufactured dust collectors, motors, fans, filter bags and other components to check whether the matching accuracy and installation positions of the components are correct. During the pre-installation process, timely adjustments and corrections are made to any problems found to ensure the smooth progress of the subsequent formal assembly.
2. Electrical connection: According to the electrical schematic diagram, make correct electrical connections to the motor, control switch, power cord, etc. During the connection process, ensure that the insulation performance of the wires is good and the wiring is firm and reliable to prevent electrical faults such as false connection and short circuit. At the same time, the electrical system should be grounded to improve the safety of the equipment.
3. Overall assembly: After completing the electrical connection, assemble all parts as per the design requirements. First install the motor and fan on the main frame of the vacuum cleaner, then install the dust collection cylinder, filter bag and other parts, and finally install the operation panel, nozzle and other accessories. During the assembly process, use appropriate tools and fastening methods to ensure that all parts are firmly installed and the overall structure is stable.
4. Debugging and testing: After assembly, the vacuum cleaner is fully debugged and tested. First, a no-load running test is conducted to check whether the motor is running smoothly, whether the fan air volume is normal, whether the control switch is sensitive, etc. Then a load test is conducted to simulate the actual working environment and test the vacuum cleaner's dust collection capacity, filtering effect and other performance indicators. At the same time, strict tests are conducted on the equipment's sealing, safety and other aspects to ensure that the product meets relevant standards and quality requirements. Only products that pass various tests can enter the packaging stage and eventually flow to the market.
Installation and maintenance guide for single-phase double-barrel bagged industrial vacuum cleaners
Installation Process
- Pre-installation preparation
Before installation, carefully check whether the equipment and accessories are complete, including the main unit, dust collection tube, filter bag, vacuum hose, suction nozzle, power cord, mounting screws and other parts. At the same time, ensure that the installation site meets the requirements, select a well-ventilated, dry area without flammable and explosive items, and avoid installation in a humid, high-temperature or dust-intensive environment. In addition, confirm that there is a stable and reliable power supply near the installation location, and the power supply voltage is consistent with the rated voltage of the vacuum cleaner.
- Host Installation
Place the vacuum cleaner on a flat, stable surface to ensure that it does not shake or tip over easily. If it is a mobile vacuum cleaner, install the rollers and adjust the height of the rollers to keep the main unit level. For fixed installation, use expansion screws and other fixing devices to firmly install the main unit in the designated position according to the design plan.
- Installation of dust collection tube and filter bag
Install the two dust collection barrels to the corresponding positions of the main unit according to the instructions, and use sealing strips or sealing rings to ensure the sealing of the joints to prevent dust leakage. When installing the filter bag, first carefully put the filter bag on the filter bag frame, and then install the frame with the filter bag to the fixed position in the dust collection barrel, ensuring that the filter bag is installed firmly and flatly without wrinkles or damage to avoid affecting the filtering effect.
- Vacuum pipe connection
Connect the vacuum hose to the vacuum port and nozzle of the main unit according to actual use needs. When connecting, make sure that the hose fits tightly to the interface. You can use a clamp or other fixings to further reinforce it to prevent the hose from falling off during vacuuming. If you need to install multiple vacuum ports, you also need to arrange the vacuum ducts reasonably and minimize the bending angle and length of the ducts to reduce air flow resistance and improve vacuuming efficiency.
- Electrical Connections
Before making electrical connections, make sure the power supply is disconnected to avoid the risk of electric shock. Connect one end of the power cord to the power interface of the vacuum cleaner and the other end to a power socket or distribution box that meets safety standards. During the wiring process, strictly follow the electrical schematic diagram to ensure that the live wire, neutral wire and ground wire are connected correctly, the wire joints are firm and reliable, and are wrapped with insulating tape to prevent leakage.
Debugging Tips
- No-load running test
After installation, do not connect the vacuum pipe and nozzle, and start the vacuum cleaner for no-load operation test. Observe whether the motor runs smoothly and whether there is any abnormal noise or vibration. Check whether the fan is turning correctly, which can be determined by observing the airflow direction at the fan outlet. At the same time, check whether the control switch is sensitive and whether the indicator lights are displayed normally. The no-load operation time is generally 5-10 minutes. Make sure that there is no abnormality in the equipment before proceeding to the next step of debugging.
- Load running test
After the no-load operation is normal, connect the vacuum pipe and nozzle, and perform a load operation test in a simulated actual working environment. Place some simulated dust or debris on the ground, start the vacuum cleaner and observe its vacuuming effect. Check whether the suction force meets the design requirements, whether the dust collection tube and filter bag are well sealed, and whether there is any dust leakage. During the test, pay attention to the motor current, temperature and other parameters to ensure that the equipment can operate stably under load and all indicators are within the normal range.
- Dust cleaning system debugging
For vacuum cleaners equipped with automatic pulse cleaning systems, it is necessary to adjust the pulse valve's blowing pressure, blowing time, and blowing interval. By adjusting these parameters, the cleaning system can effectively remove dust from the filter bag surface while avoiding damage to the filter bag due to excessive blowing pressure or too long a blowing time. After the debugging is completed, perform multiple cleaning operation tests to ensure that the cleaning system operates normally and reliably.
Daily maintenance
1. Clean the dust bin regularly
Clean the dust and debris in the dust collection bin regularly according to the frequency of use and the amount of dust. When the dust in the dust collection bin reaches about 2/3 of its capacity, it should be cleaned in time. When cleaning, turn off the power first, wait until the equipment stops running completely, open the discharge port of the dust collection bin, and pour the dust into the designated collection container. After cleaning, check whether the sealing strip of the dust collection bin is intact. If it is damaged, replace it in time to ensure the sealing of the dust collection bin.
2. Checking and replacing filter bags
Regularly check the use of the filter bag, observe the dust accumulation on the surface of the filter bag and whether there is any damage or aging. Generally speaking, when the dust layer on the surface of the filter bag is thick and affects the suction of the vacuum cleaner, it is necessary to clean the filter bag or replace the filter bag. For manual dust-vibrating vacuum cleaners, the filter bag can be cleaned by the manual dust-vibrating device; for automatic pulse dust-cleaning vacuum cleaners, ensure that the dust-cleaning system works normally and remove the dust on the surface of the filter bag in time. If the filter bag is damaged or aged, it should be replaced with a new one immediately to ensure the filtering effect of the vacuum cleaner.
3. Maintaining motors and fans
Regularly check the running condition of the motor and fan, check whether the motor bearings need to be lubricated, and ensure that the motor rotates flexibly. Clean the dust and debris on the surface of the motor and fan to prevent dust from entering the motor and affecting its heat dissipation and normal operation. At the same time, check whether the fan blades are worn or deformed. If there are any problems, they should be repaired or replaced in time.
4. Maintaining the vacuum line
Check the vacuum hose and pipes for damage or air leakage. If damaged, repair or replace them in time. Clean the dust in the vacuum pipes regularly. You can use special pipe cleaning tools, such as pipe brushes and vacuum cleaner nozzles, to prevent pipe blockage and affect the vacuuming effect. In addition, pay attention to avoid excessive bending and folding of the vacuum pipes to prevent damage to the pipes.
Common faults and solutions
1. Insufficient suction
Possible causes include filter bag blockage, vacuum pipe leakage, fan failure, motor speed reduction, etc. The solution is to first check the filter bag, if there is blockage, clean or replace it; check the connections of the vacuum pipe and repair the leaking parts; check whether the fan blades are worn or dusty, clean or replace the fan; check the power supply voltage and speed of the motor, if there is any abnormality, repair or replace the motor in time.
2. The motor does not run
It may be caused by loose power cord connection, damaged switch, burnt motor, etc. First check whether the power cord is firmly connected and whether the switch is working properly. If there is any problem, repair or replace it accordingly. If the power cord and switch are normal, the motor may be burnt. At this time, professionals are required to inspect and repair the motor and replace it with a new one if necessary.
3. Unusual noise or vibration
It may be caused by unbalanced fan blades, damaged motor bearings, loose installation of the vacuum cleaner, etc. Check whether the fan blades have foreign matter attached or are deformed. If so, clean or repair the blades; check whether the motor bearings are worn or lack lubricating oil, and replace the bearings or add lubricating oil in time; check whether the vacuum cleaner is installed firmly, re-fix the equipment to ensure its smooth operation.
How to determine the cause of failure of a single-phase double-barrel bag industrial vacuum cleaner?
When a single-phase double-barrel bag industrial vacuum cleaner fails, you can observe the failure phenomenon and gradually troubleshoot the possible causes from the core components and systems of the equipment. The following introduces specific methods for determining the causes of common failures:
Cause determination of insufficient suction failure
Insufficient suction is a common fault. The cause can be determined from the following aspects:
1. Check the filter bag status: Filter bag blockage is a common factor leading to insufficient suction. Open the dust collection tube and check whether there is a lot of dust accumulated on the surface of the filter bag. If the dust layer is too thick, it will hinder air circulation and reduce suction. In addition, check whether the filter bag is damaged. A damaged filter bag will cause some air to be discharged directly without effective filtration, resulting in reduced suction.
2. Check the vacuum pipe: Carefully check the connections of the vacuum hose and pipe to see if there are any loose, cracked or poorly sealed parts. Leakage will reduce the negative pressure inside the vacuum cleaner, thereby weakening the suction power. At the same time, check whether there are any foreign objects blocking the pipe, such as large debris or tangled fibers, which affect air circulation.
3. Check the fan and motor: Check whether the fan blades are worn or deformed. Worn and deformed blades will affect the fan's air volume and air pressure, which will lead to insufficient suction. Use professional tools to check the motor speed. If the motor speed drops, it may be due to internal motor winding failure, unstable power supply voltage, etc., which will also cause the suction to weaken.
Motor failure reason determination
When the motor does not run, follow the steps below to determine the cause of the fault:
1. Check the power connection: Check whether the power cord is damaged or broken, and whether the plug is firmly connected to the socket. Use a tester or multimeter to check whether the power socket has power and whether the power cord is powered normally. If the power cord is loose or damaged, the motor will not be able to get power.
2. Check the control switch: Check whether the control switch is damaged. For example, oxidation or ablation of the internal contacts of the switch will cause the circuit to be blocked. You can try to press or toggle the switch several times to see if there is any poor contact. You can also use a multimeter to check the on/off status of the switch in different states.
3. Check the motor itself: If the power connection and control switch are normal, the motor may be faulty. Check whether the motor winding is short-circuited or open-circuited. You can use a multimeter to measure the resistance value of the motor winding. If the resistance value is abnormal, it indicates that there is a problem with the motor winding. In addition, the motor bearing is stuck and the motor cannot run. You can manually turn the motor shaft to feel whether it rotates smoothly. If the resistance is large or it cannot rotate, it means that the bearing may be damaged.
Determine the cause of abnormal noise or vibration
If the vacuum cleaner makes abnormal noise or vibration, the cause of the fault can be determined from the following aspects:
1. Check the fan parts: Check whether there are foreign objects attached to the fan blades, such as large dust lumps and fiber entanglement, which will cause the fan to lose balance during operation and produce abnormal noise and vibration. At the same time, check whether the fan blades are deformed or worn. Deformed or worn blades will cause vibration when rotating at high speed.
2. Check the motor bearings: Wear or lack of lubricating oil in the motor bearings will cause friction noise and vibration when the motor is running. You can judge by listening to the sound. If the noise is a continuous "buzzing" or "clicking" sound, and it changes with the motor speed, it is likely that there is a problem with the bearings. In addition, touch the motor housing with your hand to feel whether the vibration is abnormally strong.
3. Check the installation of the equipment: Check whether the vacuum cleaner main unit is firmly installed, whether the roller of the mobile vacuum cleaner is installed in place and stable, and whether the fixing screws of the fixed vacuum cleaner are loose. If the installation is not firm, the equipment will produce noise and vibration due to resonance when it is running. Check whether the vacuum pipe connection is tight. Loose pipes may also produce noise under the impact of airflow.
