What are the requirements for mechanical seal installation

Mechanical seal is a high-precision mechanical component, which plays an important role in the stable operation of mechanical equipment and good use effect. When installing seals, in order to ensure the later use effect, what requirements need to be met?

1. Shaft curvature: no more than 0.05mm.

2. Rotor vibration: the vicinity of the shaft sleeve at the sealing ring of the mechanical seal is not more than 0.06 mm.

3. The axial movement of the shaft is not allowed to exceed ±0.5 mm. If the shaft sleeve is provided, the shaft sleeve is not allowed to be loose.

4. Coupling alignment error: not more than 0.08-0.10 mm (P2008C) for gear couplings, and not more than 0.05-0.06 mm for elastic couplings. (It is customary to jump on the side
