Vertical water ring vacuum pump

Abstract

The invention relates to a vacuum obtaining device, and in particular relates to a vertical water ring vacuum pump. The vertical water ring vacuum pump comprises a stator part, a rotor part, a bracket and a motor, wherein the stator part comprises a base, a pump body, a distributing round disc and a pump cover. The rotor part comprises a pump shaft and an impeller, wherein the rotor part is vertical to the horizontal plane. Eccentric distance e between the rotor part and the distributing round disc on the horizontal panel along the direction vertical to the central line of an air inlet is arranged. The pump shaft sequentially penetrates through the bracket, the pump cover, the distributing round disc and the pump body from top to bottom. The motor is connected with the pump shaft through a coupler for transmitting torque. The impeller is suspended in an inner cavity of the pump body. The vertical water ring vacuum pump provided by the invention is simple in structure, convenient to manufacture and install, low in manufacturing cost, small in occupied area and high in work efficiency.

Description

technical field [0001] The invention relates to vacuum obtaining equipment, in particular to a vertical water ring vacuum pump. Background technique [0002] The water ring vacuum pump is the equipment with the largest pumping capacity and the most widely used rough vacuum. Since the process of compressing gas by the water ring vacuum pump is isothermal, it can remove flammable and explosive gases, and also remove dust and water-containing gases. It is precisely because of its above-mentioned characteristics that it is widely used in chemical industry, In metallurgy, coal, petroleum, electric power and many other industries, the application of water ring pumps is increasing day by day. [0003] But the water ring vacuum pump is a kind of equipment with high energy consumption and low efficiency. Based on its design principle and structural characteristics, the water ring vacuum pump must use water as the working fluid during its operation to form a water ring to do work. ...

AI Technical Summary

Problems solved by technology

Existing water ring vacuum pumps are all horizontal structures, and the rotor parts are parallel to the horizontal plane. The water ring rotation process consumes a lot of power and reduces the efficiency of the pump.

The horizontal water ring vacuum pump is bulky, and the motor installation position must be reserved on the chassis, so it consumes a lot of raw materials, occupies a large area, and is inconvenient for installation and maintenance.
