1.Due to the leakage phenomenon caused by cavitation, we need to install automatic exhaust valve and replace the machine seal.
2.Due to poor water quality, containing small particles and medium hydrochloride content high, formation of abrasive wear of the mechanical seal of the plane or surface strain groove, ring groove phenomenon. We can improve the hydraulic pressure or media, the replacement of mechanical seals.
3.Water shortages caused by the dry mill damage, we need to exhaust pipe and pump cavity air, replace the mechanical seal.
4.To observe the mechanical seal static ring plane, such as severe burning phenomenon, a black plane and deep traces, sealing rubber hardens, loss of elasticity, this phenomenon is due to the installation caused by tight. We can adjust the installation height, after the impeller installation, with a screwdriver to pull the spring, the spring after the 2-4MM can be moved away from the distance.
5.To observe the mechanical seal dynamic and static ring plane, its surface has a thin layer of the scale, be able to wipe the surface, no wear. This is the spring to lose flexibility and poor assembly, or the motor caused by the axial movement, when we just need to install the spring can be.
