The causes for the leakage of

1, the seal ring connection screw, screw, pressure ring is loose. 2, sealing ring rolling is lax. 3, sealing ring connected by corrosion. 4, sealing and welding of ontology, welding quality is poor. Maintenance methods

1, screw, compression ring cleaning, replacement of damaged parts, grinding seal and connection closed surface, repackaging. For corrosion damage big larger parts, can repair welding, adhesive and so on way.

2, sealed rolling leaked should note adhesive rolling fixed again. 3, sealing ring junction surface corrosion, grinding are available, and bonding methods such as repair, should replace the sealing ring are used when beyond repair. 4, sealing ring should be according to the applied welding specification to don't understand the repair welding. Surfacing welding place cannot repair welding should be cleared when the original surfacing welding and machining.
