Self-priming pump is commonly used in the South a pump. The principle is the use of water flow momentum, impeller driven pump impeller to the river above the water. The pump can be pumped into the river to pump water, but it must be in immediate rush or fall. Self-priming pumps and centrifugal pumps in general different. Centrifugal pump Before work, the pump body and the inlet pipe must be full of water into a vacuum state, when the impeller is rapidly rotating, the blade to promote rapid rotation of water, rotating water from the impeller in the centrifugal force to fly, the pump After the water is thrown out, the central part of the impeller forms a vacuum area. Suwon's water pressure in the air pressure (or water pressure) under pressure through the pipe into the water pipe. This endless cycle, you can achieve continuous pumping. Self-priming pump is not required for irrigation, which is the origin of self-priming pump. Self-priming pump self-priming principle: Due to the special design of the pump housing. The sealing performance than the average centrifugal pump high, and the pump out of the water after the motor is out of service will not automatically drain, the motor driven turbine high-speed rotation, the rapid formation of negative pressure pump (vacuum). The use of atmospheric pressure to the pump shell, and then centrifugal lift. Therefore, the self-priming pump suction will not exceed one atmosphere, about 11M.
