How to replace the mechanical seal of water ring vacuum pump

Water ring vacuum pump mechanical seal, the method of replacing the vacuum pump mechanical seal The method of replacing the vacuum pump mechanical seal and the method of replacing the centrifugal pump mechanical seal are basically the same, except that the equipment needs to be disassembled when replacing the vacuum pump mechanical seal with a mechanical seal. The special tool for the impeller of the water ring vacuum pump can replace the mechanical seal of the vacuum pump with a mechanical seal. Before replacing the mechanical seal of the vacuum pump, it is necessary to manufacture special tools. 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 to pass through the shaft head on the center of the impeller from the center hole, and tighten the screw firmly. The impeller can be pulled out. When replacing the mechanical seal of the vacuum pump, be sure to wipe the mechanical seal clean. The place where the mechanical seal is installed should also be wiped clean. After installing the mechanical seal, heat the impeller hole with fire for about 15-20 minutes. Just install the impeller of the water ring vacuum pump directly. If you find that there is no complete installation when installing the impeller, you can quickly hit it with a hammer. When hitting with a hammer, place an iron sheet on the impeller that is larger than the impeller hole, preferably slightly thicker to avoid damaging the impeller.
