Embodiment Construction

[0022] Such as figure 1 , a jet pump provided with an internal diversion structure, the pump body 1 is cylindrical with an open rear end. In the pump body 1, an injector 2, an inner deflector 3, a forward swirl cover 4, an annular liquid guide 6, an impeller chamber 5 and a rear swirl cover 7 are provided in sequence from front to back. A pump body water inlet 1.1 is provided near the top of the front end of the pump body 1, and a pump body water outlet 1.2 is provided above the rear end of the pump body 1.

[0023] The injector 2 is composed of an injector water inlet 2.1, a nozzle 2.2, and a nozzle pipe 2.3. The injector 2 is fixed by connecting the pump body water inlet 1.1 inside the injector water inlet 2.1 of the head, and the lower end of the injector water inlet 2.1 is provided with Conical nozzle 2.2, the rear end of the nozzle 2.2 is provided with a cylindrical spray pipe 2.3 concentric with it. The end of the nozzle pipe 2.3 is connected to the connecting channel ...

Abstract

The invention relates to an injection pump with an inner flow guide structure. An injector, a front vortex cover, an annular liquid guide part, an impeller chamber and a rear vortex cover are sequentially arranged in a pump body from front to back. According to the design, an inner flow guide piece is arranged between the injector and the front vortex cover; a connecting channel is formed in the center of the inner flow guide piece, a partition plate is arranged in the connecting channel, and a plurality of spiral flow guide blades are arranged between the connecting channel and the outer wall of the inner flow guide piece; a spray pipe at the rear end of the injector is internally connected to the connecting channel of the inner flow guide piece; and the impeller chamber communicates with the spray pipe and the connecting channel. The injection pump has the advantages that fluid flows orderly, fluid pressure fluctuation tends to be stable, disordered impact on the interior of the pump body is smaller, loss is reduced, efficiency is higher, noise is lower, and the service life of machine parts is longer.

Description

technical field [0001] The invention relates to a mechanical structure of a pump, in particular to a jet pump with a flow guiding structure inside. Background technique [0002] Jet pumps are used in various fields due to their high-lift characteristics. The principle is to add an injector on the basis of ordinary centrifugal pumps to double-pressurize part of the fluid, thereby achieving the purpose of increasing the lift. At the same time, due to the internal The complexity of the cavity also makes the fluid flow relatively turbulent, resulting in reduced efficiency and more noise. Traditional jet pumps are not equipped with internal diversion facilities, part of the fluid flows directly to the outlet of the pump body, and the other part rushes to various places inside the pump body in a disorderly manner, and part of the fluid rushing to various places in an orderly manner passes through the nozzle and enters the injector The fluid entering from the water inlet of the in...
