Problems solved by technology

However, improving the sealing of the impeller of the pump body increases the production cost of the water pump; and, in arid areas, the water level is relatively deep, and it is difficult to achieve by improving the sealing performance of the impeller and the pump body and compressing the internal air pressure of the water inlet pipe; The way of pumping water, there are limitations in pumping water

Abstract

The invention discloses a novel water pump, and relates to the technical field of water pumps. The novel water pump comprises a water presser assembly and a water pump assembly; the water presser assembly comprises a water pressing cylinder main body, a water inlet pipe, a water inlet one-way valve, a water pressing one-way valve and a water pressing handle, wherein the water inlet one-way valve is used for limiting one-way flowing of gas or liquid in a direction of a water pump, and the water pressing one-way valve is used for limiting flowing of the gas or liquid towards the end, away from the water inlet pipe, of the water pressing cylinder main body; and the water pump assembly comprises the water pump and a one-way water outlet valve, and the one-way water outlet valve is used for limiting flowing of the liquid or gas from a water inlet to a water outlet. Through the water presser assembly, water is pumped out of the water inlet pipe into the water pump; after the water enters the water pump of the water pump assembly, the water pump is turned on so that the water can be continuously transported outwards through an impeller; and pump priming operation is omitted, thus the applicability of the water pump assembly is improved, and the air tightness between a water pump body and the impeller does not need to be forced during production, so that the production cost of the water pump assembly is reduced.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a novel water pump. Background technique [0002] A water pump is a device that transports or pressurizes a liquid, that is, a machine that does work on the fluid. Water pumps have different uses, and the structural forms of water pumps corresponding to different uses are also different. For example, a centrifugal water pump transports liquid through the centrifugal force generated by the high-speed rotation of the impeller; however, conventional centrifugal water pumps need to be primed before use. When there is no liquid in the pump body of the centrifugal water pump, the impeller is idling and cannot transport the liquid. [0003] At present, in order to reduce the pump filling steps, the sealing performance of the water pump can be improved; when the impeller rotates at high speed in the pump body with high sealing performance, the liquid can be sucked into the pump bod...
