Abstract

The invention discloses an anti-vibration noise-reduction anti-cavitation vortex pump. The anti-vibration noise-reduction anti-cavitation vortex pump comprises a pump body, a valve, a backflow branch,a pressing-in opening and a pressing-out opening, wherein the backflow branch is connected between the pressing-in opening and the pressing-out opening on the pump body, the backflow branch is controlled by opening and closing the valve, and the backflow branch is used for backflow of part of liquid at the pressing-out opening into the pressing-in opening, so that the pressure of working medium liquid at the pressing-in opening is increased. Due to the fact that the cavitation performance is improved, bubbles generated by the cavitation phenomenon are reduced, the impact of bubble breakage onan impeller and the pump body is weakened, the vibration and the noise of the vortex pump during operation are reduced, and the service life of the vortex pump is prolonged.

Description

technical field [0001] The invention relates to a vortex pump, in particular to an anti-vibration, noise reduction and anti-cavitation vortex pump, which belongs to the field of fluid machinery. Background technique [0002] The pump is a general-purpose machine with a large volume and wide area and huge energy consumption. There are pumps working almost wherever there is liquid flow. Among the many pump products, the vortex pump has the advantages of high head, self-priming, gas-liquid mixed transportation, etc. It is widely used in agricultural irrigation, urban water supply and drainage, electric power and other industries. When the vortex pump is working, the liquid flows into the impeller from the pressure inlet, flows back to the flow channel after being accelerated by the impeller, and transfers energy to the liquid in the flow channel, and flows out from the pressure outlet after repeated repetitions, so that the pump has a high lift. The cavitation of the vortex pu...
