Causes & Treatments of Leakage of Electromagnetic Pulse Valve of Air Box Pulse Bag Dust Collector

With the continuous improvement of the technology of the bag dust collector in China, especially the upgrading of the skill of the cleaning system and the continuous optimization of the production process, the use of the dust collector is more and more extensive. In the course of use, the common problem of the precipitator is the leakage of the pulse valve. What are the reasons for the leakage of the pulse valve?

1. The electromagnetic pulse valve diaphragm is damaged. Generally, there is dirt in the valve, perhaps the spring film is lost or damaged, and it is necessary to check whether the coil is short-circuited or there may be poor power contact. We need to open the pulse valve to clean the diaphragm or replace the spring and diaphragm.

2. The air pressure balance hole of the electromagnetic pulse valve is blocked. If the piston is stuck, it should be good to loosen the four screws that connect the pulse valve seat to the airbag. Otherwise, the quality of the gas source is not good.

3. Compressed air contains more oil and water. When the compressed air duct is installed, the foreign matter such as rust and welding slag in the pipe was not cleaned up.

4. If the compressed air contains more oil and water, it is easy to form cylinder water, pulse valve leakage, pneumatic triplet over-pressure drop and cylinder two-way valve not working.

Therefore, the quality of compressed air is the key to the safe operation of the gas box pulse dust collector. To deal with this problem, you can use a freezer gas dryer in the air compressor outlet device, or a gas filter of the filter cartridge can be replaced at the inlet of the precipitator gas storage tank. Regularly discharge water and check the pressure difference of the gas filter. When the pressure loss reaches 0.1~0.15Mpa, replace the filter element.
