*Related Introduction*
Common sense of mechanical seal inspection:
1）The operating principle of the mechanical seal requires that there is no impurities inside the mechanical seal. Before assembling the mechanical seal, clean the moving ring, static ring, shaft sleeve and other parts completely.
2) Check whether there are defects such as scratches and cracks on the surface of the dynamic ring. These shortcomings will cause severe leakage of the mechanical seal. If possible, you can use special tools to check whether the sealing surface is flat or not. Pressure water will enter the dynamic ring sealing surface of the mechanical seal after assembly, separating the dynamic ring and causing the mechanical seal to fail. If necessary, the tooling can be manufactured before assembling the water pressure test.
3) Check whether the dynamic ring seat has shortcomings that affect the seal. If the dynamic ring seat and the dynamic ring seal ring match the appearance, is there any disadvantage?
4) Check whether the mechanical seal compensation spring is damaged or deformed, and whether the tenacity coefficient has changed.
5) Check whether the seal sleeve has shortcomings such as burrs and groove marks.
6) Clean up and check whether there are cracks, pores and other shortcomings in all sealing rubber rings, and measure whether the diameter of the rubber ring is within the scope of official service.
7) For mechanical seals with pumping tissues, check whether the spiral line of the screw pump has defects such as cracks and broken wires.
