If the solenoid pulse valve fails to operate, it will affect the dust cleaning effect of the bag filter . When encountering such a situation, you can troubleshoot and solve the problem by following these simple steps. I. Check the Power Supply and Circuits
First, check whether the power indicator light of the pulse valve is on. If it is off, check for any looseness or damage to the power cord, and ensure that the plug and socket are in good contact. If the appearance of the circuit is normal, then check the fuse in the control circuit. Replace the fuse with a new one of the same specification if it is blown.
If the indicator light is on but the pulse valve still does not respond, touch the coil with your hand. If it feels extremely hot (significantly higher than the normal temperature), the coil may be faulty. Check whether the pins of the coil are poorly soldered or if there are any broken wires. If there are any issues, re - solder the connections or replace the coil.
II. Inspect the Mechanical Components
Press the test button of the pulse valve manually. If there is no response, it is highly likely that the valve core is stuck. Close the air inlet valve of the air bag, and after the pressure is completely released, disassemble the pulse valve to check whether there is dust, impurities, or rust on the valve core. If there is, wipe it off with a clean cloth and apply a few drops of lubricating oil. If the valve core is severely worn, replace it directl
The diaphragm is also a component prone to problems. After disassembling the pulse valve, check whether the diaphragm has cracks or damage, and whether there are any foreign objects on the sealing surface. Replace the diaphragm if it is damaged, and clean up any foreign objects. Remember to clean the air chamber when replacing the diaphragm.
III. Examine the Pneumatic System
Check the pressure of the air bag. The normal operating pressure is generally between 0.4 - 0.7MPa. If the pressure is too low, the pulse valve will not operate properly. If the pressure is low, check whether the air compressor is working normally and whether the pipeline filter is blocked. Clean or replace the filter element in a timely manner if it is blocked.
Check for air leaks at the blowpipe, joints, and diaphragm sealing areas. Apply soapy water to these areas. If bubbles appear, it indicates a leak. For leaks at the blowpipe welds, re-weld them; for leaks at the joints, replace the sealing rings; and for problems with the diaphragm sealing surface, polish it.
IV. Consider Aging Factors
If the solenoid pulse valve has been in use for a long time or has a high usage frequency, exceeding its normal service life, its components are prone to aging and failure. In such a case, directly replacing the pulse valve with a new one can quickly solve the problem.
Most problems with the non - operation of the solenoid pulse valve can be resolved through the above simple troubleshooting and handling. If the problem persists, it is recommended to contact a professional maintenance personnel for further inspection.
