AI Technical Summary

Technical Problem

Existing water ring vacuum pump cleaning methods involve cumbersome disassembly and assembly procedures, high risk of impeller damage, and low cleaning efficiency.

Method used

A water ring vacuum pump cleaning device was designed, including a positioning seat, a turntable, a cleaning component and a motor. The servo motor drives the screw sleeve to cooperate with the screw, so that the spray cleaning module enters the blade spacing space and uses spray cleaning fluid to clean the blade surface and the inner wall of the shell. The stepper motor drives the turntable to rotate intermittently to achieve automated cleaning.

Benefits of technology

Cleaning can be completed without disassembling the impeller, avoiding impeller damage, significantly improving cleaning efficiency and effectiveness, and simplifying the cleaning process.

Abstract

The invention discloses a water ring vacuum pump cleaning device, and relates to the technical field of pump machine maintenance, the water ring vacuum pump cleaning device is characterized in that a positioning seat is rotatably connected with a rotating disc, the rotating disc and an impeller of a water ring vacuum pump are coaxially arranged, and the positioning seat is provided with a resistance pressing plate elastically abutted against and matched with the impeller; the cleaning assembly is arranged on the rotary disc through a support and comprises a guide rod, a screw, a threaded sleeve, a spraying module and a servo motor, the guide rod is slidably arranged on the support in the axial direction of the impeller, the spraying module is arranged at one end of the guide rod, the screw is parallel to and fixedly connected with the guide rod, the threaded sleeve is rotationally connected to the support and is in threaded connection with the screw, and the servo motor drives the threaded sleeve to rotate. The screw rod, the guide rod and the spray-washing module move in the axial direction of the impeller, and the spray-washing module enters an interval space between two adjacent blades of the impeller and sprays cleaning liquid to the surfaces of the blades and the inner wall of a shell of the water ring vacuum pump; and the stepping motor drives the turntable to intermittently rotate on the positioning seat, so that the spray-washing module sequentially enters each interval space of the impeller for cleaning operation.
