Abstract

The invention discloses a high-pressure water pump internally provided with a backflow cavity. The high-pressure water pump comprises a peripheral pump body. The backflow cavity is arranged between a water inlet of the peripheral pump body and a flow pass. A backflow channel is arranged in the backflow cavity. According to the high-pressure water pump internally provided with the backflow cavity, as the backflow channel is arranged in the backflow cavity, in the working process, the water flow speed is increased, rotation is achieved through water flow, the pressure intensity in the pump is kept high all the time, and the phenomenon of water pressure instability is avoided.

Description

technical field [0001] The invention belongs to the technical field of high-pressure water pumps, and in particular relates to a high-pressure water pump with a built-in return cavity. Background technique [0002] The small size and light weight of the vortex pump have great advantages in marine installations; it has self-priming ability or can be self-priming with the help of simple devices; the vortex pump has a simple structure, and the casting and processing processes are easy to realize. Pump parts can also use non-metallic materials, such as plastic, nylon molded impeller, etc. Therefore, as a high-pressure water pump, the vortex pump is widely used in shipbuilding, textile, chemical industry, metallurgy, machinery manufacturing, aquaculture, fixed fire protection, heat exchange unit, agricultural remote sprinkler irrigation and other departments. [0003] The liquid in the vane groove of the vortex pump is thrown to the flow channel by centrifugal force, and pressur...
