Detailed explain of filter’ working principle

　　When the filter start to work, profession wholesale grease filter said the water, which needed been filter would flowing through the filter screen first, and enter into the needed pipelines through all exit and do the continue procedure circulation, so all grain impurities, which exist in the water would been hold back in the inner space of filter screen, so wholesale grease filter said under the help of this continue circulation, these would be more and more grain impurities had been hold back, so the filtering speed would become slower and slower as well, but because lots of dirty water had flowing into the filter screen, so the filter holes would become smaller and smaller, so there would has a pressure difference between the exit and inlet.

　　After the pressure difference close to set pressure, the differential pressure transmitter would send the singles to control device, and the control system would driving the motor to ensure all transmission parts can drive the axle to turning, wholesale grease filter said all dirty water discharge exit would be open at this time and all dirty water would been discharged out.
