Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] figure 1 Shown is an exploded view of the structure of the water ring vacuum pump, which is mainly composed of a pump cover 1, a disc 2, an impeller 3, a pump body 4 and a motor 5. In the present invention, both the pump body 4 and the pump cover 1 are made of composite materials with nylon as the base material. Glass fibers are added to the composite material for reinforcement, and the content of glass fibers in parts by mass can be 15%, 20%, 35%, etc. Carbon fiber is added to the composite material, and the content of carbon fiber in parts by mass can be 5%, 8%, 10%, etc.

[0021] In the present invention, nylon is used as the base material for manufacturing the pump body and the pump cover. Compared with metals, nylon has a higher elastic modulus, wear resistance, shock absorption and sound attenuation. Nylon is resistan...

Abstract

The invention discloses a wear-resistant corrosion-resistant water-ring vacuum pump, belonging to the field of pumps. The wear-resistant corrosion-resistant water-ring vacuum pump comprises a pump body and a pump cover. The wear-resistant corrosion-resistant water-ring vacuum pump is characterized in that both the pump body and pump cover are made from a nylon-based composite material. The corrosion resistance and wear resistance of the pump are greatly enhanced; the pump is convenient to install; the combination tightness between the pump body and pump cover is enhanced; the weight and operation noise of the pump are greatly lowered; and the service life of the pump is prolonged.

Description

technical field [0001] The invention belongs to the field of pumps, in particular to a water ring vacuum pump. Background technique [0002] Most of the water ring vacuum pumps currently in operation in the world are made of metal materials. During the operation of the water ring vacuum pump, the situation of being cut and corroded is very serious and prominent. Since the water ring vacuum pump adopts a water-sealed form, during the operation of the equipment, the high rotation of the water in the pump body will produce the effect of cutting the water jet, which will produce linear cutting on the pump body, causing the pump body to be scrapped due to the damage caused by cutting. Due to the environment in which the water ring vacuum pump is located, its workpieces are also severely corroded, including water corrosion, medium corrosion, electrochemical corrosion and the most fatal cavitation. These corrosions reduce the efficiency and performance of the water ring vacuum pu...
