Rubber seals, rubber oil seal end face damage, mechanical rubber oil seal improper maintenance or improper operation caused by mechanical seal damage and other forms of oil seal failure. Such as the failure of the auxiliary rubber oil seal, the spring failure of the rubber buffer oil seal compensation mechanism, the reason for the break of the moving seal ring, etc.
The flushing method has been changed, the original automatic flushing has been changed to the external flushing oil seal method, because the water in the device system contains more suspended particles, so the oil seal fluid is introduced from the outside and injected into the oil seal cavity, thereby changing the oil seal working environment (occasion), after the system is pressurized by the high pressure pump, it enters the oil seal cavity of the mechanical seal to flush the mechanical seal.
Fearing the presence of fine solid particles, they can accumulate over time and then damage the mechanical seal. Therefore, two sets of filters are added to the machine-sealed flush water main, and the filters are replaced and cleaned from time to time to ensure water quality, and the above is an improvement measure on the cleaning method of rubber oil seals.
