Auto excretory function - trapped surface discharge was intercepted impurities in raw water through the filter layer, impurities in the water was blocked automatic pool suction dirt machine, the filter layer resistance increases, causing the water level rises Wuhan pool sewage suction machine, when the water level rises to a certain high , according to principles of fluid mechanics automatic drain, automatic flushing, automatic recovery filter, filter self-aligned reset. Flushing intensity 32L / m2.s, rinse lasted 2min, after reaching the filter quality (turbidity) <4mg / L. The gravity filter works: raw water from the inlet pipe into the filter, the filter layer filter from top to bottom, clear water that is poured into the village from the communication pipe storage tank after the tank is filled, the water through the outlet pipe into the clean water tank, continued retention of suspended matter filter layer pool sewage suction machine, resulting in increasing the resistance of the filter layer, which has prompted siphon the water level continues to rise. When the water level reaches the siphon tube when the auxiliary port, water falls Shandong pool sewage suction machine, through the exhaust pipe so as to fall away siphon tube in the air, when the vacuum reaches a certain value, then the siphon effect from the tube. Then water in the water from the bottom up through the filter layer of filter backwash. When the flush tank below the surface down to siphon tube, air enters the siphon, siphon effect damage.
