In order to operate the liquid ring vacuum pump normally, daily maintenance is very important. Cleaning is a maintenance work. How to do this work? Let’s introduce the cleaning measures of liquid ring vacuum pump:
1. In the initial cleaning, in order to save money, recycle gasoline can be used first, then wash gasoline, and finally clean it with aviation gasoline. Then check the damage and scratches carefully.

3. If rusty or burred parts are found, they can be lightly polished with oilstone or metallographic sandpaper to remove rust spots and burr. Pay attention to the smoothness of the parts.
4. For the through-hole, oil tank and gas channel of the oil way, the accumulated particle impurities, dust, dirt and oil dregs shall be cleaned, and the place with shell shall be removed gently. Finally, use compressed air to blow the oil way through and dry it. Make sure that there is no gasoline or solvent for cleaning in the oil way slot.
