*Related Introduction*

Installation of mechanical seals: Seals refer to the parts that play a blocking and sealing effect in order to prevent external dust and impurities from entering the machine body and prevent the medium in the machine body from leaking to the outside during the normal operation of mechanical equipment. There are many types of seals, and most of the seals used as static seals are non-metal, semi-metal or metal gaskets or gaskets, such as rubber gaskets, asbestos flat gaskets with metal mesh, and copper flat gaskets; As seals for touch-type dynamic seals, commonly used are felt ring, gland packing, O-shaped sealing ring and V-shaped (Y-shaped, u-shaped) sealing ring, etc. Non-touch dynamic seals often use annular gap seals, bend (labyrinth) seals, etc.

Before installing the seal, you should first know the orientation of the seal in the installation diagram, the mechanical seal type, and the installation sequence, and then check the appearance and processing quality and mutual cooperation accuracy of the seals to be installed, and check for cracks and scratches , Deformation, damage, etc., creating conditions for smooth installation.

We often encounter deformation of the friction pair of the seal during equipment seal maintenance. In order to ensure the flatness of the friction pair, grinding and polishing are required. Grinding and polishing processes generally use abrasives, liquids and abrasive tools to grind and polish the surface of the static and dynamic rings that are time-sealed to obtain a predetermined shape and surface roughness. It is a high-precision processing method as well as a processing method for high-hardness materials. The surface of the mechanical seal friction pair requires high flatness and small roughness, which is difficult to achieve by general processing methods, so it needs to be solved by grinding and polishing.
