The quality inspection of mechanical seals does not mean that a simple test is enough, it should be summarized from the production process, technology and application. First of all, we need to figure out what a mechanical seal is. In fact, it is an oil seal device for a rotating machine. With the cooperation, the retaining sticker is combined with a relatively slippery composition to avoid fluid leakage. Therefore, the equipment quality requirements of mechanical seals are very high.

There are many inspection methods for mechanical seals. Our general inspection methods and steps are mainly determined according to the material itself. Firstly, the radial runout of the equipment shaft should be≤0.04 mm, and the axial movement is not allowed to be greater than 0.1 mm; it is strictly forbidden to bump and hit during the installation process, so as to avoid damage to the mechanical seal and the seal failure; the surface in contact with the seal should be coated with a layer of cleaning agent during installation. Mechanical oil for smooth installation; when installing the static ring gland, the tightening screws must be evenly stressed to ensure the straightness of the end face of the static ring and the axis line; after installation, there should be no feeling of weight when turning the shaft by hand; It must be filled with medium before work to avoid drying and causing the seal to fail.


Mechanical seals need not be affected by external changes in the application environment, and their own dissection and softening requirements are relatively high, otherwise, problems in application quality will easily occur. In order to ensure the safety and longevity of its application; the corrosion resistance and aging resistance requirements of mechanical seals are also very high, and the degree of wear resistance will directly affect the life of its application. When processing mechanical seals, many other factors also need to be considered.
