Small-sized stamping and injection molding self-priming pump

Abstract

The invention relates to a small-sized stamping and injection molding self-priming pump which comprises a motor, a water inlet / outlet section and a base. The water inlet / outlet section is provided with a water inlet and a water outlet. An impeller is connected to an output shaft of the motor. A sealing base plate and a mechanism seal are mounted between the impeller and the motor. The sealing baseplate is assembled on the motor. The mechanism seal sleeves the output shaft of the motor, and is arranged between the sealing base plate and the impeller. A guide vane and a guide vane seat are arranged inside the water inlet / outlet section. The guide vane and the impeller are coaxially arranged and mounted on the impeller. The other end of the guide vane is connected onto the guide vane seat. Ajet device is mounted between the guide vane and the water inlet in the water inlet / outlet section. The water inlet / outlet section, the sealing base plate and the motor are all mounted on the base. Compared with the prior art, the small-sized stamping and injection molding self-priming pump is novel and simple in structure, and reasonable in design, the suction of a water pump is increased, the lift is increased, the efficiency is improved, the problem that the water is polluted since a casting water pump is rusted is solved, the weight of the water pump is reduced, so that the whole water pump is lightened, environmental-friendly and worthy of popularization and application.

Description

[technical field] [0001] The invention relates to the technical field of water pumps, in particular to a small stamping injection molding self-priming pump. [Background technique] [0002] At present, the existing small self-priming pumps are usually open centrifugal impellers or vortex impellers, resulting in low suction, low head, long self-priming time, and low efficiency. The traditional manufacturing method of water pumps is usually casting, and casting is A process with high power consumption, many consumables, high labor intensity, and pollution to the environment; for some parts of the small flow pump, such as the impeller, its outlet width is very narrow, and it cannot be cast due to the limitation of the process. Heavy, the water pump is easy to rust, and has certain pollution to water quality. [Content of the invention] [0003] The purpose of the present invention is to solve the above-mentioned deficiencies and provide a small stamping injection molding self-...
