Do you know what is the reason for the failure of the sealing ring? Let's follow the editor of fluorine rubber ring from China manufacturer for a brief understanding.
1. The material selection of the mechanical rubber sealing ring is inappropriate
The material of the mechanical rubber seal does not match the medium being conveyed. During operation, the sealing elements are quickly corroded, dissolved or worn, thus losing their sealing ability. Therefore, selecting the material of the mechanical seal according to the nature of the conveying medium is a prerequisite for ensuring its sealing function and normal life.
2. The flushing condition of the mechanical rubber seal does not meet the design requirements
When transporting media that is easy to crystallize or has fine particles, a certain pressure and a certain flow of flushing liquid are required for flushing, otherwise the crystals or particles will accelerate the wear of the sealing pair, and affect the automatic compensation of the sealing pair after wear and leakage occurs. Therefore, according to the nature of the conveying medium, it is not only necessary to configure the corresponding flushing pipeline, but also to install instruments and devices with monitoring and adjustment functions to ensure that the pressure and flow of the flushing liquid meet the design requirements, so as to maintain the normal operation of the mechanical seal. This is often ignored by users.

3. The working pressure of the mechanical rubber seal exceeds the bearing value
There is a limit to the pressure that each mechanical rubber sealing ring can withstand. Due to the inaccurate measurement of the pressure in the sealing chamber, the pressure in the sealing chamber exceeds the pressure that the mechanical rubber sealing ring can withstand, resulting in leakage. It is also common One of the reasons for seal failure.
The above is what the editor of fluorine rubber ring from China manufacturer tells:A brief introduction to the knowledge about the reasons for the failure of the sealing ring.
