Some vacuum pump users have found that the vacuum pump is leaking oil and even spraying oil, but they do not know the specific reason, which makes it difficult to solve. Here, LVGE will tell you reasons for vacuum pump oil leakage.
The direct cause of oil leakage is sealing problems. It is recommended to use professional leak detection equipment for testing. As seal failure may occur on the oil mist filter or on the vacuum pump, we need to check the sealing of the entire vacuum system. Firstly, check whether the connections of the entire vacuum system are tightly connected and whether there is any wear. Then, investigate each component one by one.
However, the reasons for sealing failure are numerous and complex. For example, the oil seal may be scratched during the assembly process, or deform due to the pressure, which both lead to oil leakage.
What’s more, many people often overlook an accessory - the oil seal spring. The elasticity of the oil seal spring may also vary depending on the material and quality. If the elasticity is insufficient, it will cause wear on the oil seal.
Different vacuum pump oils have different compositions and may react chemically with certain impurities. Moreover, some vacuum pump oils originally have quality issues, which can easily soften or harden the oil seal material. This will also cause the oil seal to fail.
The above are common causes of oil leakage in vacuum pumps. To be honest, there are other reasons that can cause the oil leakage of vacuum pumps. The best way is to find professionals to investigate on-site. In China, we usually analyze the reasons through video or living, and even assign specialists to investigate on-site. We have been engaged in the field of vacuum filtration for over ten years. Click the picture, follow us to learn more. Welcome to contact us.
