Zibo water ring vacuum pump

Using polymer composite materials to repair and protect common corrosion,abrasion and other problems of Zibo water ring vacuum pump;An analysis was conducted on the common corrosion and abrasion issues of Zibo water ring vacuum pump;An analysis and explanation were conducted on the advantages of using polymer composite repair agents for protective applications.

Zibo water ring vacuum pump is a coarse vacuum pump that can achieve a vacuum of 2000-4000Pa,and can be connected in series with an atmospheric injector to reach 270-670Pa.The vacuum pump is equipped with an eccentric rotor with fixed blades,which throws water(liquid)towards the stator wall,forming a liquid ring concentric with the stator.The liquid ring,together with the rotor blades,constitutes a variable volume rotary vacuum pump.Zibo water ring vacuum pump has the advantages of simple structure,easy processing,uniform suction,stable and reliable operation,simple operation,and convenient maintenance.

Due to the isothermal compression of gases in vacuum pumps,flammable and explosive gases can be extracted.Due to the absence of exhaust valves and friction surfaces,dust laden gases,condensable gases,and gas water mixtures can be extracted.With these outstanding characteristics,despite its low efficiency,it has been widely used in industrial enterprises such as petroleum,chemical,machinery,papermaking,mining,light industry,medicine,and food.
With the increasing application of Zibo water ring vacuum pump,the equipment is often affected by harsh environments such as high temperature,high pressure,strong corrosion,and cavitation erosion during operation,which often leads to wear,corrosion,leakage,and other phenomena,restricting the normal production of enterprises and even causing serious safety accidents such as fires,explosions,and pollution.The main causes of corrosion can be summarized as follows:
After multiple cycles of water in the Zibo water ring vacuum pump,not only does the acidity increase,but the water ring turbulence can also come into full contact with carbon monoxide,making the water acidic and causing electrochemical corrosion conditions at the flow passage of the vacuum pump,resulting in corrosion of flow passage components such as impellers.
Due to changes in boundary conditions,the Zibo water ring vacuum pump may experience an increase in local flow velocity,resulting in negative pressure on the back of the impeller.This can easily lead to cavitation and the formation of a large number of bubbles during use.In the discharge stage,the bubbles are rapidly ruptured under pressure,and the resulting shock wave acts like a"water hammer",which is enough to damage the metal surface.The material of the pump body is mostly cast iron,but due to its poor wear resistance and corrosion resistance,it causes corrosion and wear of the pump body.
