The maintenance of the pump should pay attention to several main parts.
1. Rolling bearings: when the pump is running for a long time, bearing wear to a certain extent.
2.Before sealing ring, after the sealing ring sealing ring when the sealing ring wear to a certain extent to illustrate the change.
3. Mechanical Seal: mechanical seal in oil spill condition, should not generally open inspection. If the lower bearing body place of leak serious leakage, is to illustrate the dismantling of mechanical seal. Assembly and disassembly of mechanical seal. Must handle with care, attention to the surface of the ditch clean with. The protection of static ring and moving ring engraved surface, it is strictly prohibited to knock. Because of the mechanical seal and leakage is the main reason for galling to mirror friction. The repairing method can be used for grinding the face of the friction pair to restore the surface of the mirror surface. Mechanical seal leakage of another reason is O type rubber sealing biosphere (or cushion) improper installation, or deformation aging to. Then you need to adjust or replace the computer "O" ring and re assembly.
