Working principle of air filter:

In the process of air filtration, the self-cleaning air filter cartridge gradually increases the pressure difference between the inside and outside of the air flow passing through the high-efficiency filter element due to the adsorption of dust. When the pressure difference between the inside and outside of the filter element is greater than a certain set value,“Pulse controller”It starts automatically and controls“pulse valve”In a very short period of time, use compressed air to perform a programmed pulse backwash from the inside out on each row of filter elements to remove the accumulated dust adsorbed on the filter elements; When the filter element is washed clean (i.e. the pressure difference between the inside and outside is less than a certain set value or after several cycles of backwashing), the flushing process stops automatically. Due to the fact that the compressed air for backwashing is passed through“Venturi tube”Inject into the filter element, so not only does it consume very little air, but it also has strong explosive power and good flushing effect. Pulse cleaning does not significantly affect the normal operation of gas equipment.

The clean air chamber outlet of the self-cleaning air filter is connected to the inlet of the air compressor, and under the action of negative pressure, process air is sucked in from the atmosphere. The air passes through the filter cartridge, and dust is blocked by the filter material. Countless small particles of dust form a dust film on the windward surface of the filter material. Dust film can improve filtration efficiency and increase airflow resistance. When the resistance increases to the high limit600PaWhen the pressure difference transmitter transmits the resistance signal to the computer in the pulse control device, the computer sends instructions and the self-cleaning system starts working; After receiving the command, the solenoid valve controls and drives the diaphragm valve according to the program, and the diaphragm valve instantly releases compressed air with a pressure of600～800 kPaAfter being rectified by the nozzle, the dust on the outer surface of the filter material is blown off by blowing back from the inside of the filter cartridge, and the resistance decreases accordingly. When the resistance reaches the initial resistance of the filter material(about150Pa)When the self-cleaning system stops working.Spray powder 320X660 dust removal filter element

Working in construction machinery and trucks with poor working conditions, the air intake quality does not meet the requirements,Directly affecting the service life of locomotives. Replace the original paper core of the car,The price is quite expensive,Maintaining it is very inconvenient. Many car owners adopt the method of adding a first stage oil bath air filter on the basis of the original car air filter to solve the problem. The effect is very good. The cost-effectiveness is very high. Better than replacing the entire assembly.
