Notes For Installation And Use Of Mechanical Seal
- Aug 15, 2018 -

(1) radial run-out  to lerance during installation: 0.04 ~ 0.06MM, 0.03 MM axial run-out of rotor, 0.04 ~ 0.06MM surface run-out tolerance.

Radial run-out tolerance: mechanical seal shaft or sleeve at a point of roundness and shaft relative to the baseline deviation.

Rotor axial channeling: the inevitable small movement of the shaft along the axis during operation

Surface run-out tolerance: the run-out tolerance between the cavity and the sealing end cover on the shaft surface

(2) confirm whether the component models are consistent, whether the parts are complete, and pay attention to the rotation of the rotating shaft.

(3) installation steps: confirm the installation size and install mechanical seal parts for lubrication and loading the transmission components.

(4) when using, pay attention to impurity particles, whether the torque is too large, pay attention to the rotation, and at first open the medium and cooling water valve, abnormal sound and overheating before operation.
