If the impeller of the sealing oil vacuum pump 30-WS is damaged, it will cause insufficient vacuum. During the non operation of the vacuum pump rotor in the pump body, friction may occur, which can easily lead to wear, fracture, expansion, and other phenomena of the vacuum pump blades without vacuum pump oil lubrication. This can cause damage to the sealing oil vacuum pump impeller, resulting in insufficient vacuum and inability to lift the vacuum.

 

A pump is a mechanical device that transports or pressurizes fluids. It transfers the mechanical energy or other external energy of the prime mover to the liquid, increasing the energy of the liquid.
