A water pump is a machine that delivers or pressurizes a liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid, mainly for transporting liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. It also transports liquids, gas mixtures and liquids containing suspended solids.
Water Pump Set includes Easy to Start and Low Noise Petrol Trash Water Pump, Easy to Start and Low Noise Petrol Self-Priming Water Pump, Easy to Start and Low Noise Petrol High Pressure Water Pump, self priming water pump and high pressure water pump, etc.
The high-pressure water pump is a high-lift pump with high pressure and long service life. The main applications are pumping, spraying, rinsing and irrigation.
The 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 service life and strong self-priming capability. The pipeline does not need to be installed with a bottom valve. It is only necessary to ensure that the pump body has a quantitative liquid before the work. Different materials can be self-priming pumps of different materials.
The working principle of the self-priming pump is to fill the pump casing with water before the pump starts (or the pump itself contains water). After the start, the impeller rotates at a high speed to make the water in the impeller channel flow toward the volute. At this time, the inlet forms a vacuum, so that the inlet water stops the door, and the air in the suction pipe enters the pump and reaches the outer edge through the impeller channel.
