Damage to the floating seal ring

  • Release on:2020-11-02
The use of any object has certain limiting factors, so damage is inevitable. But there are also differences in the damage situation and nature. Such as wear and damage in the application of floating seal ring:

Each type of sealing element has a certain service life. After long-term wear and tear, the air sealing performance cannot be guaranteed, and leakage will occur. In the operation of machinery and equipment, due to various impurities entering or improper coordination, the sealing element may Corresponding parts were damaged to varying degrees, resulting in leakage at the sealing part. In addition, although the working surface of the mechanical seal device is protected by lubricating oil, the formation and maintenance of the lubricating oil film are conditional. Due to the different working conditions and lubrication conditions of the machinery, the distribution of the oil film on the working surface and the lubrication conditions are also different. Same, so there will still be a worn bite state.

For static seals, insufficient pre-tightening force or uneven pre-tightening force causes leakage of machinery and equipment under working conditions, and improper adjustment during assembly causes leakage during equipment operation; the sealing end face is loose or missing due to positioning screws Tighten, the gland (the static ring component of the static type is the pressure plate) is not compressed; when the sealing end is installed, it is not cleaned, and there are granular impurities; the dynamic and static ring seals are not compressed or the compression is not enough, etc. Damage to the floating seal ring caused by use is defined as damage.
