Introduction of suction filter

The water enters from the water inlet, firstly passes through the coarse filter to filter out larger particles of impurities, and then reaches the fine filter. During the filtration process, the fine filter gradually accumulates dirt and impurities in the water to form a filter impurity layer. Since the impurity layer accumulates on the inner side of the fine filter, a pressure difference is formed between the inner and outer sides of the fine filter.

. When the pressure difference of the filter reaches the preset value of the filter, the automatic cleaning process will begin. During this time, the supply of clean water will continue to flow, the cleaning valve will be opened, and the water pressure in the cleaning chamber and the sewage suction device will drop significantly.

The pressure difference of the pipe produces a suction force between the filter suction pipe and the cleaning chamber through the suction nozzle, forming a sewage suction process. At the same time, the filter electric motor drives the sewage suction pipe to make a spiral motion in the axial direction. The combination of the axial movement and the rotational movement of the dust collector completely cleans the inner surface of the entire filter screen.

The entire flushing process takes only tens of seconds. The drain valve closes at the end of the cleaning. The filter begins to prepare for the next flush cycle.
