Do you know how to drain oil from liquid ring vacuum pump? Let's learn more today!
1. If you want to drain all the oil in the liquid ring vacuum pump box, you can unscrew the drain plug at the lower part of the box to drain the oil.
2. When the liquid ring vacuum pump discharges oil, the height of liquid level from the top plate of the oil tank shall not exceed 30mm to ensure the lubrication and cooling of each bearing in the pump. When the volume of Jack working chamber is too large, additional oil tank shall be set to ensure that the minimum height of liquid level after oil discharge is not less than 100mm to avoid suction.
3. After the first 500h operation of the speed regulating hydraulic Siemens liquid ring vacuum pump, the oil tank and oil filter shall be changed and cleaned. Test the oil quality by visual inspection and laboratory test, and change the oil in time when the oil quality deteriorates. The oil tank and oil filter must be cleaned at the same time when changing oil. If there are metal chips or water in the oil, find out the cause and remove the fault.
4. In a short time when the liquid level drops, the bearing is lubricated by the oil attached and the oil splashed by the plunger spring. The oil filter of the oil tank and the oil filter under the pump are made of 230 mesh / inch copper wire mesh. The oil filter mesh should be cleaned frequently to prevent blocking. When in use, the oil temperature of the oil tank should not exceed 60 ℃, and appropriate measures should be taken to cool it if necessary.
