vacuum pump of three filtering forms

The vacuum pump filter is called the vacuum pump oil mist filter element. It is a part designed to maintain the efficient and normal operation of the vacuum pump and prolong the service life of the vacuum pump. It plays a very good role in protecting the vacuum pump. Generally, the vacuum pump needs three filtering forms at the same time.

Air inlet filtration: intercept the solid particles in the inhaled gas. Through the interception of large impurities and dust particles, the pressure of two-level filtration at the rear end is greatly reduced, the mechanical wear during the operation of the vacuum pump is reduced, and the service life of the vacuum pump is extended.

Filtration of vacuum pump oil: oil type vacuum pump uses vacuum pump oil as the medium to vacuum. During the operation of vacuum pump, the oil will gradually carbonize and deteriorate under high temperature, and gradually gelatinize. In addition, the vacuum pump blades and other parts will also have friction during rotation, which will produce some dust particles. These gelled oil and dust particles will run together in the vacuum pump oil, so they must be collected in time through the oil filter. At this time, the vacuum pump filter can play a good role in protection, and the dirt is collected and contained by it.

Exhaust filtration: The exhaust gas from the vacuum pump contains a large number of oil mist particles. If the oil mist particles are not separated, they will be discharged with the gas, forming what is commonly called “smoke”. The vacuum pump “smoke”, which will pollute the working environment of the workshop, and the vacuum pump oil will also drain very quickly. It is necessary to refuel the vacuum pump every day. At this time, the exhaust filter can solve this problem. When the oil and gas mixture is discharged, it needs to pass through the high-precision glass fiber filter paper of the exhaust filter. The oil mist particles cannot pass through the glass fiber filter paper directly in the form of liquid, so they attach to the filter paper. Finally, more and more oil mist particles attach to the filter paper and are integrated into the oil drop reflux vacuum pump. Clean gas is discharged smoothly through the glass fiber filter paper under a certain pressure, so that the vacuum pump filter can achieve the role of oil and gas separation.
