Working principle
Automatic scraper self-cleaning filters achieve water purification and equipment protection through the following steps:
Water flow into: the water to be treated enters the filter body by the water inlet, and the impurities in the water deposit on the stainless steel wedge net, forming a pressure difference.
Differential pressure monitoring: The differential pressure change of the inlet and outlet is monitored through the differential pressure switch. When the differential pressure reaches the set value, the electronic controller sends a signal to the control valve and the drive motor.
Automatic cleaning: the motor drives the brush to rotate and clean the filter element, while the control valve is opened for blowdown. The whole cleaning process only takes tens of seconds, after the end of cleaning, the control valve is closed, the motor stops rotating, the system is restored to the initial state, and the next filtration process is entered.
Product characteristics
Simple structure: The design structure is simple, easy to operate and maintain.
Short reverse cleaning time: large flow, small pressure loss (≤0.018MPa), adjustable cleaning time (60 seconds).
Intelligent control: The system can be connected to DCS, with differential pressure, time and manual control.
High precision filtration: the effluent water quality is stable, the sewage consumption is <1%, the filter is used for life, no need to replace.
Long life and low operating costs: fewer wearing parts, no consumables in the overall structure, reducing maintenance costs.
Flexibility: can be applied to different raw water quality and water requirements, simple operation and management.
Automatic reverse cleaning: ensures a continuous supply of clean water.
