Fixing and Applying Directions of Mechanical Seals

 

 

1. Select Appropriate mechanical seal to match the materials according to work conditions and host machine equipment.

2. The radial acting deviation for the shaft(shaft sleeve) of the installed mechanical seal shall be 0.04mm by maximum while the axial movement value of the rotor shall be no more than 0.1mm.

3. When installing the mechanical seals,the shaft(shaft sleeve),seal chamber,seal face as well as the mechanical seal face
should be 0.04mm by maximum.

4. When conveying medium of over high or low temperature,with medium which are easy catch fire,easy for explosion.Related mechanical seal standards must be referred to take appropriate measures such as quench,rinsing,coolong and filtrating.

5. Appropricate lubrication must be choosen when mechanical seal is installed.The installment size of the mechanical seal must be guaranteed to the installment instruction.

6. Before the machine starts running,the hermetic compartment shall be full of medium and well lubricated.Dry friction which may lead to the damage of the air-tightness is strict forbidden.
