Fixing and Applying Directions of Mechanical Seals
1. 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.
2. 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.
3. Appropricate lubrication must be choosen when mechanical seal is installed.The installment size of the mechanical
seal must be guaranteed to the installment instruction.
4. 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.
