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
must be cleaned in order to keep from any medium to sealing part.
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.
