In the disassembly of mechanical seal, prohibited the use of hammer and chisel, so as not to damage the sealing element. If the sealing element is bonded to the dirt or agglomerate, the seal must be removed to remove the mechanical seal. If there are mechanical seals at both ends of a centrifugal pump, it must be careful in the demolition process, prevent the care for this and lose that.
On the mechanical seal, if loose gland sealing surface move, you should replace the static ring parts should not be re tightened continue to use. Because after loosening, the friction pair of the original running track will change, the contact surface of the sealing is easy to be destroyed
