China 2BV water ring vacuum pump

As a universal machinery,pumps have been widely used in various fields of the national economy.The China 2BV water ring vacuum pump is a coarse vacuum pump equipped with an eccentric rotor with fixed blades.It throws water(liquid)towards the stator wall,forming a liquid ring concentric with the stator.The liquid ring and rotor blades together form a variable volume rotating variable volume vacuum pump.

During the use of China 2BV water ring vacuum pump,if the conveying medium contains solid particles or due to cavitation,the shell and impeller will be damaged,mostly in the form of thinning or even perforation of the substrate.Once the above situation occurs,it will have a significant impact on the safe operation and pump efficiency of the pump,and in severe cases,it may even cause equipment shutdown.Although many manufacturers have used a large amount of high hardness metals in material selection according to user requirements,which has played a certain role,the cost is too high and the effect is not very ideal.
In order to reduce the repair cost of China 2BV water ring vacuum pump and considering the cost-effectiveness of the repair,it has been decided to use this technology to repair the pump body.By using polymer composite materials,the working temperature during repair and protection is low,overcoming the thermal stress deformation caused by welding and spray melting processes,and the construction process is simple;Due to its unique molecular structure,it endows high elasticity and adapts to alternating deformation and temperature changes,ensuring improved shock absorption and wear resistance of the material.It can resist wear,erosion,and other working conditions in most environments.Polymer materials have excellent anti-corrosion properties,resisting corrosion from most low-temperature organic and inorganic acids,which can greatly extend the service life of components.
