Self priming pump: self priming pump does not water reasons and treatment

Time: 2021-12-21

Treatment method: plug the inlet by hand, add water power, suction may be small water seal broken suction is the inlet leakage. General suction 30 seconds to lift the hand pump with, (first try pump leakage is not) safety first.

The working principle of self-priming pump is to fill the pump shell with water before the pump starts (or there is water in the pump shell itself). After starting, the impeller rotates at high speed to make the water flow in the impeller groove to the vortex shell, then the inlet forms a vacuum, the inlet check door is opened, the air in the suction pipe enters the pump, and reaches the outer edge through the impeller groove.

Self-priming pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming capacity. There is no need to install the bottom valve in the pipeline, and only need to ensure that there is quantitative liquid injection in the pump body before working. Different liquids can use different materials of self-priming pump.

ZW type self-priming pump is based on the relevant technical data at home and abroad by absorption, digestion, improved after the development of energy-saving pump products. The pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, convenient maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install the bottom valve in the pipeline, only need to keep the pump body to store quantitative liquid before work, so the pipeline system is simplified, to improve the working conditions.

Main uses:

2. Equipped with rocker nozzle, the water can be rushed into the air and scattered into small raindrops for spray. It is a good machine for farms, nurseries, orchards and tea gardens.

3, suitable for clean water, sea water and chemical medium liquid with acid, alkalinity and with general paste slurry (medium viscosity ≤ centiper, solid content can be up to 30% below).

4, can be used with any type, specifications of filter press, the slurry to the filter press for the best matching pump.

ZW type self-priming non-clogging sewage pump, is based on ZX type self-priming centrifugal pump and QW type submersible sewage pump structure and performance, learn from the advantages of similar products abroad, developed from the collection of self-priming and sewage in a new type of pump. Can be like water self-priming pump generally do not need to install the bottom valve, without irrigation water diversion, and suction contained a large of exit diameter solid particles and fiber length is 60% of the impeller diameter of 1.5 times the dirt, sediment, goaf impurities, waste treatment and all engineering sewage and colloidal liquid, completely, reduce the labor intensity of human and installation is convenient to use, very little maintenance, The performance has reached the international advanced level, with broad application market and development prospects.
