Abstract

The invention provides a high-efficiency injection pump and belongs to the technical field of water pumps. The high-efficiency injection pump solves the problem that the working efficiency of an existing injection pump is low. The high-efficiency injection pump comprises a pump body, a motor, a rotating shaft and an impeller, wherein a circulating body is arranged in the pump body. The circulatingbody comprises a water inlet and a water outlet, and the pump body comprises a water outlet cavity and a pressurization cavity, wherein the pump body is provided with a water outlet end. The circulating body comprises a body with a cavity, and a cylindrical injection channel is arranged in the cavity of the body, the injection channel divides the cavity of the body into a water inlet channel anda water outlet channel, the two ends of the injection channel are respectively communicated with the water inlet channel and the water outlet channel, the outer end of the water inlet channel is a water inlet, the outer end of the water outlet channel is the water outlet, a backflow hole communicated with the water outlet cavity is formed in the body, and the backflow hole is disposed at the end,close to the water inlet channel, of the injection channel. The high-efficiency injection pump has the advantage of being high in working efficiency.

Description

technical field [0001] The invention belongs to the technical field of water pumps, and relates to a jet pump, in particular to a high-efficiency jet pump. Background technique [0002] The jet pump is a pump that uses the jet action of high-pressure and high-speed working fluid to transport fluid. The liquid flowing back in the pump body forms a high-speed flow through the nozzle of the flow channel body, and a low-pressure area is formed around the high-speed flow, so that the liquid or gas-liquid at the water inlet The mixture can be inhaled continuously. The high-speed flow and the low-speed flow of the water inlet are mixed in the throat part, which increases the speed of the water flow entering the impeller, so that the jet pump has a higher lift. The white suction function and high head of the jet pump are the main reasons why it is favored by the market. A garden pump is a type of jet pump. [0003] For example, the flow passage body structure of a garden pump dis...
