Abstract

The invention belongs to the technical field of vacuum equipment, in particular to an anti-corrosive anti-wear water-ring vacuum pump which comprises a pump body and a pump cover fixedly connected together, and a motor. A rotary shaft of the motor penetrates through the pump body so as to be inserted into a pump cavity enclosed by the pump body and the pump cover; an impeller arranged on the rotary shaft, a circular disc fixed between the pump body and the pump cover, and a seal suite arranged between the rotary shaft and the pump body are arranged in the pump cavity; the impeller comprises ahub, and multiple blades arranged along a circumferential direction of the hub in a spaced manner; each blade is arranged along an axial direction of the hub; an included angle is arranged between each blade and a radial direction of the hub; a reinforcement hoop is connected between the end parts, close to one side of the circular disk, of each two adjacent blades; the pump body, the pump cover,the impeller and the circular disk are integrally injection-molded by nylon or PPS (Polyphenylene Sulfite) plastics. According to the anti-corrosive anti-wear water-ring vacuum pump, the problems of poor corrosion resistance and wear resistance and poor impeller stability of an existing water-ring vacuum pump are solved, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of vacuum equipment, in particular to a corrosion-resistant and wear-resistant water ring vacuum pump. Background technique [0002] In chemical and pharmaceutical fields, water ring vacuum pumps are often used to pump some corrosive gases, which seriously shortens the life of water ring vacuum pumps, and requires relatively high corrosion resistance for water ring vacuum pumps. At present, since the pump body, pump cover, impeller, and disc of the water ring vacuum pump are all made of metal materials, and the pump body, pump cover, impeller, and disc will be in direct contact with corrosive gases or working media during operation Contact, easy to cause corrosion and wear, resulting in water ring vacuum pump leakage or even can not pump gas, in order to enhance anti-corrosion and wear resistance Spray a layer of protective layer on the top, but the protective layer often cracks and falls off, which not onl...
