Preparatory work and precautions before the placement of mechanical seals

Preparatory work and matters needing attention before installing the mechanical seal:

Be sure to make preparations before installing the mechanical seal:

1. If the mechanical seal is replaced with a new one, it is necessary to check whether the model and specification of the mechanical seal are correct, and whether the quality meets the specifications;

2. The end of the anti-rotation groove at the end of the static ring and the top of the anti-rotation pin should be connected with an axial gap of 1mm-2mm to avoid buffer failure;

3. Clean the end faces of the dynamic and static rings with alcohol, and clean the rest of the metal parts with gasoline and dry them with clean compressed air. Check carefully to ensure that there is no damage to the sealing surfaces of the dynamic and static rings. Before assembly, two pieces“0”The round rubber sealing ring should be coated with a layer of lubricating oil, and the end faces of the dynamic and static rings should not be oiled. The components of the mechanical seal and their related assembly contact surfaces must be cleaned with acetone or absolute alcohol before installation. The installation process should be kept clean, especially the dynamic and static rings and auxiliary sealing components should be free of impurities and dust. The surfaces of the dynamic and static rings are coated with a layer of clean engine oil or turbine oil.
