1. All kinds of sewage pump mechanical seal device should be checked carefully before running mechanical seal parts number is consistent with the need, each component is damaged, especially the dynamic and static ring any dent, crack, deformation defects such as.If you have questions, need corrections or replace new parts.

2. Check the collar or gland chamfering is appropriate, it necessary to repair does not meet the need.

3. Before diving sewage pump mechanical seal equipment operation, it is necessary to clean clean contact mechanical sealof each components and related equipment.Should adhere to in the process of cleaning equipment, especially the surface of the dynamic and static ring and assisted packing element should without impurities and dust.Dynamic and static ring surface coated with a layer of clean machine oil or turbine oil.

4. To prevent gland end deflection, after coupling correction, pumps with mechanical seal to tighten the gland bolts should be uniform and with a feeler to check each point, the error is not more than 0.05 mm.

5. Check with feeler gland and shaft or sleeve diameter collaboration space (namely concentricity), adjacent to uniform, each with allowable error is not greater than 0. L0mm.

6. Spring deflation quantity should comply with the rules, admit of no too big or too small, allowable error, 00 plus or minus 2 mm.When the crunch of the end face specific pressure increases, accelerate the end wear;Hours, lack of specific pressure, not seal.Spring loaded inside the spring seat move should be adjustable.Equipment single spring, should pay attention to the helical spring, its XuanXiangYing and axial shift in the opposite direction.

7. Equipment ring, should guarantee can loose move, after the spring ring pressure should be automatically bounce back.

8. Equipment, static ring, first will seal trap in static ring back again into the seal inside the end cover of mechanical seals, the vertical degree of static ring end face and the center line of the end cover should conform to the technical needs, static ring back anti-rotating slot should be on the stop pin, but can't contact.In the process of equipment, do not damage the static ring end face.

9. Equipment process, never allow struck packing element with things, to prevent the damage of packing element.
