Answer: Correct operation and use are crucial to the life of the mechanical seal. The 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. This is especially important when starting the air compressor after maintenance.
(2) The piping system connected to the equipment must also be cleaned. If the debris in the system is not cleaned in time, after long-term operation, the debris may enter the seal, thereby affecting the life of the seal. Most of the premature failure of the seal of new equipment is caused by this reason.
(3) For newly installed equipment, slight leakage may occur at the beginning of the first operation. This is a normal phenomenon. As the seal is running-in, the leakage will decrease until there is no leakage. However, if the leakage continues for a long time, it means that the auxiliary sealing system may be damaged or the sealing surface is damaged.
(4) During the operation of the air compressor, if the vibration amplitude of the main engine increases, it should be handled in time to prevent the failure of the mechanical seal.
