Liquid ring vacuum pump of sand particles entering treatment

The key of liquid ring vacuum pump in use is to prevent some sand particles from entering the mechanical equipment, but it is inevitable to enter some mechanical equipment in use. What should be done after sand particles enter the mechanical equipment?

It is considered that impurities are not allowed to enter the inner cavity of mechanical equipment in use, and the impeller may be blocked and unable to rotate in the process of running with liquid in the inner cavity, which will lead to the damage of mechanical equipment in operation. Even some high hardness sand will damage the impeller of mechanical equipment, so the mechanical equipment does not have good vacuum performance in operation, thus affecting the production efficiency.

In this case, it is necessary to use a two-stage grit chamber. In many mold industries, due to the use of mechanical equipment will enter more sand, the service life of general liquid ring vacuum pump is relatively short, but the use of grit chamber equipment will be greatly extended. In addition, the vacuum performance of mechanical equipment is not affected after use, and the energy used is much less than before. This is because if the vacuum performance is improved, the production efficiency will certainly be improved.

The above explanation is the solution after the liquid ring vacuum pump enters the sand particles. Some sand particles enter the equipment frequently, so the service life of mechanical equipment is greatly shortened. Because when sand particles enter the cavity of mechanical equipment, it will affect many parts.
