We introduce several methods for you in case of no cost:
1. The most simple way:
self priming sewage pump pump
water pump in the pump, pump start before the pump starts, the vacuum pump to start, so that the first water filled with water pump, to ensure that the pump automatically, quickly start. This way of water absorption requires a sound automatic control system to ensure the normal operation of the system.
2. Relatively simple: self priming
pump to reduce the water inlet pipe curve, height and level of the gap between the.
3. A little trouble, but very easy to use:
self priming pump set before the pump suction tank. This way is needed in a suction tank set the pump suction pipe, water pump in the first operation, artificial internal tank filled with water, the first run to stop, because the water inlet pipe is higher than the height of the water tank inside the tube height of the water tank, despite the height of the water tank is lower than the water level, water tank can't go back, into the pool, so the water absorption can be stored, and because water tank outlet pipe (i.e. pump suction pipe) tube height is lower than the height of the water, so it can ensure the pump suction tube filled with water, and then after the
pump is running, the water in the water tank is pumped away. On the negative pressure, the water in the pool under the action of atmospheric pressure added to the water tank through the suction tank inside the pool.
4. Self suction pump suction pipe is installed at the end of the suction end of the valve. Suction end of the valve is actually a check valve, which ensures flow only from a pool into the suction tube can not turn the clock back, so if the suction tube filled with water, while the elevation axis pump the water level above the pool work, but because of the role of the suction end of the valve, the water suction tube can not flows into the pool, can enable the suction tube has been filled with water to ensure the pump can automatically and quickly start.
