A miniature two-stage vortex pump hydraulic thruster

Abstract

The invention proposes a miniature two-stage vortex pump hydraulic pusher, which includes a diversion section, a working section and a support section. The diversion section includes a volute, a first-stage guide vane body, a first-stage turbine shield, a Blade body and secondary turbine sealing ring, the working section includes propeller, secondary turbine, turbine hub, first stage turbine and main shaft, the supporting section includes bearing base, shaft cover; first stage guide vane body, first stage turbine, second stage The guide vane body and the second-stage turbine are arranged in sequence, and the volute exit channel of the volute, the first-stage guide vane body, the first-stage turbine, the second-stage guide vane body, and the second-stage turbine are connected in sequence. In the present invention, the pressurized water flow enters the first-stage guide vane body sequentially through the volute and accelerates to drive the first-stage turbine to rotate to do work. 1. The two-stage turbine and the propeller rotate along the main shaft, and the rotating propeller pushes the sewage in the sewage tank, thereby converting the work done by the two-stage turbine into the kinetic energy for pushing the sewage.

Description

technical field [0001] The invention relates to an energy conversion device, in particular to a device for converting pressurized water flow energy into rotational mechanical energy, and then directly converting the rotational mechanical energy into water flow kinetic energy. Two-stage vortex pump hydraulic thruster. Background technique [0002] The pusher used in the sewage treatment plant is a kind of push flow device in the sewage treatment production process, which is numerous and indispensable in the sewage treatment plant. At present, most of the flowmakers widely used in sewage treatment plants are electric flowmakers directly driven by electric power. The device, the electric flow booster has been working in the complicated and diverse sewage for a long time, so the motor directly connected to it is also soaked in the sewage all the year round. Due to the harsh working environment of the electric flow pusher, and some applicable occasions have special requirements...

AI Technical Summary

Problems solved by technology

Due to the harsh working environment of the electric flow pusher, and some applicable occasions have special requirements such as anti-corrosion, explosion-proof, and leakage prevention, the traditional electric flow pusher has a short service life and has disadvantages such as leakage, explosion-proof, and weak anti-corrosion performance. Its operating cost and maintenance cost are high
