Improper selection of floating oil seal materials, improper installation methods, failure to use installation tools, poor product quality, mismatch between product design and working conditions, installation gap issues, product use time too long, harsh working conditions, and improper operation methods of machinery and equipment , impurities and dirt entering when replacing parts are all causes of floating oil seal failure. In this article, we mainly talk about the following points that should be paid attention to in order to reduce oil leakage when using floating oil seals.
When installing the floating oil seal, focus on the selection of the gap value, which is also an important factor affecting sealing performance. Improper selection of the gap (please refer to other articles) may also cause the floating oil seal to fail. If the pressure during equipment operation exceeds the range that the floating oil seal can withstand, the floating oil seal will be over-compressed or deformed and damaged in advance, making it impossible to achieve effective sealing.
It should be noted that the floating oil seal is for one-time use. When replacing the parts around the floating oil seal, as long as the cavity is opened. External factors may also cause floating oil seal failure. For example, impurities such as dust, sewage, and sand will enter the seal cavity and damage the oil seal surface, causing the floating oil seal to leak. Therefore, try not to install and use the floating oil seal repeatedly, which will easily increase the risk of damage. Causing seal failure.
The floating oil seal is a precision part. If there is oil leakage and failure, it is recommended to make a comprehensive judgment based on the manufacturer’s opinions. Generally speaking, oil leakage failure requires multiple investigation and comprehensive analysis.
