Why do vacuum pumps leak? Chances are your seal is failure

It is very common for mechanical equipment to leak during operation, but the leakage of vacuum pump should not be underestimated. In severe cases, it may explode and endanger personal safety. What is the reason for the leak of the vacuum pump? The main reason is that the tightness of the pump is not up to standard, resulting in gas leakage. Generally, the sealing performance of vacuum pumps is very high, but the possibility of leakage of vacuum pumps cannot be ruled out.

Most of the leakage of the seal is due to the deformation of the sealing surface, and the leakage probability of the sealing surface is very high. Some enterprises will have corrosive gas in their working conditions, which will cause the sealing surface and sealing ring of the vacuum pump to be corroded by the gas, and leakage will occur after damage, resulting in accidents. In addition to corrosive conditions, many factors such as sealing materials, wear, and process abnormalities may result.

Before an accident happens, we have to find out where the pump is leaking and fix it quickly. How to fix pump leaks?

The air inlet can be installed with a stainless steel air intake filter. The stainless steel air intake filter of the filter has excellent sealing performance and corrosion resistance, and the leakage rate is quite low. We prevent problems before they occur and prevent leakage before it occurs possibility. However, it is not enough to replace the excellent air intake filter. Before the leakage occurs, the vacuum pump operator needs to maintain the pump regularly, find the fault of the pump as soon as possible, and quickly find the source when the leakage occurs. After the leakage occurs, it is necessary to replace the ineffective seal, install a drainage pipe at the leakage, and collect the leaked oil uniformly.

Therefore, whether it is a vacuum pump manufacturer, an application provider or a vacuum pump exhaust filter element manufacturer, it is necessary to increase the awareness of risk prevention, increase preventive measures inside the equipment, and add mitigation measures externally to ensure the safety of the vacuum pump and avoid accidents.
