When the dust collector is used in the environment of high temperature flue gas, the dust bag is selected, mainly the graphitized glass fiber cloth filter bag. In some environments, it is necessary to choose carbon fiber filter material. In the process of operation of cloth bag dust collector, the important thing is to control the speed of the flue gas through the filter material, that is, to use the filter bag to control the filtering speed.

Under normal circumstances, the filtration speed of the filter bag reaches 0.5-2m /min. If the particles in the air are greater than 0.1μm, the use rate of the filter bag can reach above. The resistance loss of the equipment of the dust collector is about 980 -- I470Pa. Therefore, in the process of dust collector work, the selection of dust bag key. Only the correct selection of the filter bag, can the dust collector work.

Note of pulse bag dust collector:

1, the dust collector unit to achieve online dust control;

2, the unit timing cleaning interval time and online cleaning time by the time relay (adjustable) automatic execution;

3. Before cleaning, attention should be paid to opening the valve on the air compressor and the equipment air bag, and there should be air source and pressure.

Maintenance method of purchase welding dust collector

1. During the operation of the equipment, special personnel should be assigned to manage the equipment and make good operation records.

2. Managers should be familiar with the principle, performance and service conditions of purchase welding dust collector, and master the adjustment of operating parameters and equipment maintenance methods.

3. Add lubricating oil to the parts that need lubrication on the equipment regularly.

4, often check whether the dust collector pulse cleaning system is normal spraying, if not, it is important to check whether the pulse valve diaphragm, pulse bag dust collector solenoid valve is lost or damaged, and should be repaired or replaced in time.

5, pulse valve such as failure, such as impurities, water and other foreign bodies, should be cleaned in time, diaphragm damage should be replaced in time.

6. Check the cylinder and flange surface of the purchase welding dust collector regularly. If air leakage is found, the sealing ring should be changed in time.

There are many reasons for excessive emission of purchase welding dust collector. Whether it is in the process of manufacturing process, or in the operation process of purchase welding dust collector, it is possible to make new mistakes in the process of maintenance. But overall, we can check more from the dust bag.
