What is the main difference between a backwashing filter and a self-cleaning filter? In fact, the backwashing filter is a form of self-cleaning filter. The washing method of the backwashing filter uses the liquid reverse flushing filter to take away impurities.I. There are several types of self-cleaning filters:Backwashing filter. Backwashing filter is divided:(1) backwashing filter of filter liquid;(2) external liquid backwashing filter.Self-cleaning filter(1) brush-type mechanical self-cleaning filter(2) scraper type mechanical self-cleaning filter, etc.Backwashing and self-cleaning filter of mechanical self-cleaning.Two, the main difference between the backwashing filter and the filter form of the self-cleaning filter1. different structures:The backwashing filter consists of carbon steel barrel, wedge-shaped stainless steel strip filter, butterfly valve and sewage collection device.

Working Principle of filter The working principle of the filter is: when the filter works,The water to be filtered enters through the nozzle,Flow through the filter screen,And enter the pipe required by the user through the outlet used for the process cycle.The particulate impurities in the water are trapped by the filter.With this continuous cycle,More and more particles have been intercepted,The filtering speed is getting slower and slower.Imported sewage is still entering continuously,The filter holes will become smaller and smaller,Causes a differential pressure between the inlet and outlet.When the difference reaches the set value,The differential pressure transmitter sends an electrical signal to the controller.The control system starts the drive motor,The drive shaft rotates through the transmission parts,At the same time, the sewage outlet is opened and discharged from the sewage outlet.When the filter is cleaned,The differential pressure drops to the minimum,And the system returns to the in
