The working principle of hydraulic oil suction filter 1:

The water enters the filter from the water inlet. The automatic filter first filters out the larger particles of impurities through the coarse filter element assembly, and then reaches the fine filter screen. After filtering out the fine particles of impurities through the fine filter screen, the clean water is discharged from the water outlet. During the filtration process, the impurities in the inner layer of the fine filter gradually accumulate, and a pressure difference is formed between the inner and outer sides of the self-cleaning pipeline filter.

The working principle of hydraulic oil suction filter 2:

The water to be treated by the hydraulic oil suction filter enters the body from the water inlet, and the impurities in the water are deposited on the stainless steel filter screen, resulting in a pressure difference. The pressure difference between the inlet and outlet is monitored by the differential pressure switch. When the pressure difference reaches the set value, the electric controller sends a signal to the hydraulic control valve and drives the motor, which triggers the following actions: the motor drives the brush to rotate, cleans the filter element, and opens the control valve at the same time. For sewage discharge, the entire cleaning process only lasts for tens of seconds. When the cleaning of the self-cleaning pipeline filter is completed, the control valve is closed, the motor stops rotating, the system returns to its initial state, and the next filtration process begins.

The working principle of the hydraulic oil suction filter is three:

The water of the automatic filter enters from the inlet, firstly filters out the impurities of larger particles through the coarse filter, 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. .
