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 screw off the drain plug at the lower part of the box to drain the oil.
2. When the liquid ring vacuum pump discharges oil outside, the liquid level shall not be more than 30mm from the top plate of the oil tank to ensure the lubrication and cooling of each bearing in the pump. When the volume of the jack working chamber is too large, additional oil tank shall be set to ensure that the minimum height of the liquid level after the oil discharge is not less than 100mm to avoid suction.
3. After the speed regulating hydraulic Siemens liquid ring vacuum pump runs for 500h for the first time, change the oil and clean the oil tank and oil filter. 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 period of 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. The oil temperature of the oil tank should not exceed 60 ℃ when in use. If necessary, appropriate measures should be taken for cooling.
