-2022-12-03-           VIEWS:0          

Suction type self-cleaning filter automatically filters raw water, automatically cleans the screen and automatically discharges dirt, the whole process is automatically controlled without manual operation, the cleaning and discharging system has uninterrupted water supply, and the control mode of suction type automatic self-cleaning filter can be automatic or manual.

Applications

Electric power, petrochemical, fine chemical, food and beverage, automotive, industrial, metallurgy, paper making, pharmaceutical, microelectronics, environmental protection water treatment and other industries.

Working Principle

Suction scanning, also known as focused backwashing. An attraction created by reversing a small portion of the fluid flowing through the filter element into a nozzle at the tip of the rotating scanning element.

The effluent enters from the inlet, is filtered through coarse and fine screens, and then flows to the outlet. During the filtration process, impurities in the water gradually accumulate on the surface of the fine screen. A filter impurity layer is formed. As the impurities accumulate on the inner side of the fine screen, a pressure difference is formed between the inner and outer sides of the fine screen. When the pressure difference reaches the preset value of the system, the automatic cleaning function is activated, during which the water supply of the system is not interrupted, the sewage valve is opened and the sewage is discharged by the sewage valve. At this time, the pressure in the hydraulic motor room and the dirt collector drops significantly, and the dirt absorption process starts: at this time, the same strong backwash water flows to the outside, and a suction force is generated on the suction nozzle, plus when the water flows through the hydraulic motor, the hydraulic piston pressure drops, driving the dirt collector to rotate around the shaft to do axial movement, and the whole inner surface of the fine screen is completely cleaned. The filter is also installed with a timing controller, which can be discharged regularly at a certain time interval. The principle of motor-driven dirt-absorbing filter is the same as above, except that the dirt collector is driven by a motor.

Customer case

Last December, a Russian customer customized a sucking filter from us. After communication, we made a technical parameter sheet, and the customer gave good feedback after purchase.
