1. Check the mechanical seal with the
design drawings, specifications, all components (especially the sealing
surface, auxiliary seal ring) requirements, damage, deformation, cracks
and other phenomena, such as a defect, to replace or repair.
2. Check the size, roughness and parallelism of the mechanical seals, and comply with the design requirements.
3. Use small spring mechanical seal, should check the length of the small spring, the same rigidity.
4.
Check the momentum, momentum and deviation meet the technical
requirements, the seal chamber in accordance with the installation size,
the sealing cover and the vertical axis, general requirements: axial
channel momentum is not greater than + / - 0.5 mm; axial throwing
(rotating seal) is not greater than 0.06 mm; the largest axial deviation
is not greater than 0.05 mm; the sealing cover and gasket contact
surface is not perpendicular to the center line, allowing 0.03 ~ 0.05
mm.
5. Should be kept
clean, especially the rotary ring and static ring, sealing surface and
auxiliary sealing surface should be free of impurities, dirt. Clean
sheets are not allowed to be cleaned with clean cloth.
6. Use tools to remove packaging elements to prevent mechanical seal damage.
