Water ring type vacuum pump

Abstract

The invention discloses a water ring type vacuum pump. The water ring type vacuum pump comprises an adjusting device, a mounting frame and a movable plate. Four vertical columns are arranged at the positions of the four corners of the mounting frame separately, a rectangular groove is formed in the side wall of one side of each vertical column, a first motor is arranged on one side of each rectangular groove, and a screw is arranged on one side of each first motor. In the working process, when the height position of a vacuum pump needs to be adjusted, second driving gears are simultaneously driven to rotate by controlling the output ends of four second motors, the second driving gears drive second transmission gears to rotate, two limiting rods synchronously rotate, then third driving gears at the two ends of the two limiting rods rotate, as four gear belts are in engaged connection with the four third driving gears separately, the movable plate is driven to move upwards, the height position of the working vacuum pump is adjusted, the height can be adjusted without stopping operation of the vacuum pump, the working efficiency is improved, and the water ring type vacuum pump is convenient to use.

Description

Technical field [0001] The invention relates to the field of vacuum pump equipment, in particular to a water ring vacuum pump. Background technique [0002] Water ring vacuum pumps are abbreviated as water ring pumps. They are widely used in many processes in the petroleum, chemical, chemical fiber, machinery, mining, power, metallurgy, textile, paper, medicine and food industries. At present, the water ring vacuum pump requires special fixed equipment when in use, the use range is greatly restricted, and it cannot be positioned during work. [0003] The Chinese patent with publication number CN202520579U discloses a water ring vacuum pump, which includes a pump body, a disc, a pump cover, an impeller and a pump shaft. The pump body, pump cover, impeller and pump shaft are coated with metal chromium coating , And a stainless steel protective layer is plated on the surface of the disc. The water ring vacuum pump also includes a mechanically sealed stuffing box, a nut and a baffle....

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a water ring vacuum pump to solve the problem that the current water ring vacuum pump needs to adjust the initial height of the bottom plate before use. Most of the existing adjustment methods first raise the bottom plate, and then assemble It takes a long time; when fixing the water ring vacuum pump, a special vacuum pump base must be used, and the base needs to be fixed, and a special fixing device is required to fix the vacuum pump. Assembly and disassembly are time-consuming and laborious, which is not conducive to maintenance; During the working process, when the height position of the vacuum pump cannot be adjusted, it is necessary to stop the operation of the vacuum pump and then adjust the height during adjustment, which reduces the working efficiency and makes the adjustment difficult; the stability of the vacuum pump when it moves upwards cannot be guaranteed during the adjustment process, which affects the stability of the vacuum pump. work problem
