A: Correct operation and use are critical to the life of mechanical seals. Precautions are as follows:
(1) Most mechanical seals are designed to work in a liquid environment, so the sealing surface must be immersed in liquid. Running without lubrication will seriously damage the sealing surface, affecting the use and life of the seal. Especially attention should be paid to the start of the air compressor after overhaul.
(2) The pipeline system connected with the equipment must also be cleaned up. If the debris of the system is not cleaned up in time, after long-term operation, debris may enter the seal and affect the life of the seal. The early failure of the new equipment is mostly caused by this.
(3) For the newly installed equipment, in the first operation, there may be a slight leakage, which is normal, with the running in the seal, the leakage will be reduced until no leakage.
However, if the leakage lasts for a long time, the auxiliary sealing system may be broken or the sealing surface may be damaged.
(4) In the operation of air compressor, the increase of host vibration amplitude should be handled in time to prevent the failure of mechanical seal.
