Precautions For Mechanical Seal Installation And Use

(1) Limaton tolerance when installing mechanical sealing: 0.04 ～ 0.06mm, 0.3mm axial movement of rotor, and the jump to the surface of 0.04 ～ 0.06mm.
Radial jump tolerance: Mechanical sealing shaft or a shaft sleeve is a round degree and a shaft. The deviation of the benchmark line is compared to the benchmark line.
Rotor axis movement: The shaft is inevitable slightly moved along the axis in the work.
Surface beating tolerance: The binding tolerance to the axis surface of the cavity and sealing end cover.
(2) Confirm whether the component model is the same, whether the parts are complete, and pay attention to the rotation of the shaft.
(3) Installation steps: Confirm that the installation size, the installation mechanical seal site is lubricated, and the transmission component is installed.
(4) Pay attention to the impurities particles, pay attention to whether the torque is too large, pay attention to the direction of the mechanical sealing, and first open the medium, cooling water valve to open, abnormal sound and overheating phenomenon. If you encounter problems, you should stop checking in time to avoid failure.
The service life of mechanical sealing should be checked regularly, and abnormalities should be replaced in time to ensure safe operation. When cleaning and repairing machinery seals, it is necessary to operate strictly in accordance with the operating regulations to avoid damage to mechanical seals. At the same time, pay attention to personal protection measures such as protective gloves and safety glasses to avoid damage.
