Self-priming water
Pump is pumping water machinery, by the pump body, rotating assembly, the faucet assembly, drain cover, and the inlet pipe, the outlet pipe, blocking the network assembled from the general; start the motor, power linkage The rotating assembly is driven by the impeller centrifuge, the bubble surges upward to generate suction and the air in the inlet pipe is discharged out of the pump body through the outlet pipe, the air is drained out, the water flows out through the outlet pipe, the water pump has excellent performance, Suction deep, flow, work save time and labor, is the best in the real society of water pump machinery. Self-priming pump works Self-priming, as the name implies, the pump suction pipe is the case of air, the use of negative pressure when the pump (vacuum), under the action of atmospheric pressure will be lower than the water pressure on the pump up, and then from Drain end of the pump discharge. This process is not before the need to add "diversion (guide water)". Pumps with this capability are called "self-priming pumps." Some centrifugal or rotary vane pump in the water before, you must add "diversion" in the pump chamber to form a closed environment, and then pump operation to form a negative pressure, to achieve the purpose of water. For example, manual pumps were used in rural areas. There is no self-priming pump, each time before adding water, "diversion", it is very troublesome. The height of self-absorption is called suction process. The unit is generally meters. Also known as the maximum height of self-absorption. That is, the maximum height at which the pump can automatically suck water (the vertical distance between the pump suction opening and the liquid to be sucked in) without adding water. Our pumps are self-priming pumps, the standard suction refers to this situation. Some centrifugal pumps do not have the ability to self-priming, the first use must add water Caixing. Although some diaphragm pumps also have self-priming capability, but the subject of the suction and the inlet pipe are often all the air can draw water under the vertical height difference, this point, please note.
