Answer: The maintenance of mechanical seals does not require special tools and materials. Generally speaking, the following tools and materials are required for the maintenance of mechanical seals:
(1) White cloth and soft paper. Cleanliness is the most basic and most critical condition in the maintenance and installation of mechanical seals. When repairing mechanical seals, it is generally not allowed to work with gloves.
(2) Clean lubricating oil. All auxiliary seals of mechanical seals have a thin layer of oil film on the contact parts. Therefore, when installing auxiliary seals, a thin layer of clean lubricating oil should be applied to the auxiliary seals. The selected lubricating oil should be soluble in the medium or sealing liquid, but cannot dissolve the auxiliary seal material. All parts that come into contact with the shaft or sleeve should also be coated with a small amount of lubricating oil during installation.
(3) Grinder or grinding plate and diamond abrasive for grinding.
(4) Hexagonal wrench for tightening the positioning screws. The positioning screws used for general mechanical seals are made of stainless steel. Inappropriate tools may damage the screws, thereby failing to tighten the dynamic ring seat well.
