2LQF6W type cooler differential pressure drain
Backpressure Sewage Discharge: Once impurities accumulate to a certain quantity, utilize the differential pressure signal between the cooling water inlet and outlet pipes for backwashing and discharging. This involves the electrical contact pressure gauge sending a control signal, which then activates the control mechanism to open the electric sewage discharge valve. The electric reducer will operate at a speed of 3-6 rotations per minute, reversing the flow of water to wash away impurities adhering to the inner wall surface of the mesh core. The waste is then discharged through the sewage pipeline and valve into the cooling water outlet pipe. One cleaning and discharge cycle takes approximately 5-10 minutes. In cases where large debris obstructs the filter mesh and it cannot reach its proper position, the electric device should run in the opposite direction to flush away the debris.
Section 2: Operating Principle of the 2LQF6W Cooler
Manual Process: After the filter is connected to the pipeline system, water enters the filter through the lower inlet. As impurities in the water pass through the core mesh, they are trapped due to their larger size compared to the mesh holes. Once accumulated to a certain quantity, a pressure difference is created between the inlet and outlet. (The pressure difference varies with the filter mesh precision diameter, generally around 0.15 Mpa.) Manually open the drain valve to start draining. Rotate the handle in either clockwise or counterclockwise direction, turning one step every 10-30 seconds. The handle is fixed at each indentation. The water reverses to flush the impurities and dirt adhering to the inner wall surface of the core mesh. Continue until a full rotation is completed, then close the drain valve to finish manual draining.
