The method of replacing the mechanical seal of the water ring vacuum pump The mechanical seal of the water ring vacuum pump, the method of replacing the mechanical seal of the vacuum pump The method of replacing the mechanical seal of the vacuum pump and the method of replacing the mechanical seal of the centrifugal pump are basically the same, except that the mechanical seal is used in the kettle When replacing the mechanical seal of the vacuum pump, it is necessary to be equipped with a special tool for dismantling the impeller of the water ring vacuum pump. The mechanical seal can be used to replace the mechanical seal of the vacuum pump. Make special tools before replacing the mechanical seal of the vacuum pump. Buy two M10 high-strength screws with a length of 45mm and one M12 high-strength screw with a length of 80mm. Fix the iron plate on the impeller with M10 screws. Use the M12 screw from the center hole to pass through the shaft head at the center of the impeller, and tighten the screw firmly. Then the impeller can be pulled out. When replacing the mechanical seal of the vacuum pump, be sure to wipe the mechanical seal clean. Clean the area where the mechanical seal is installed. After installing the mechanical seal, heat the impeller hole with fire for 15-20 minutes or so. Just install the impeller of the water ring vacuum pump directly. If you find that you haven't installed it once when installing the impeller, you can quickly strike it with a hammer.
