Vacuum pump used for a long time, will produce a lot of oil, we have to do is to drain these oil, prevent the oil from blocking the pipeline, affecting the use of equipment, so what should we do?

If you want to drain all the oil in the vacuum pump box, you can screw off the drain plug at the bottom of the box to drain the oil.

When the vacuum pump is discharging oil, the height of the liquid level from the top plate of the oil tank should not exceed 30mm to ensure the lubrication and cooling of the bearings 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 100 mm, so as to avoid air suction.

The oil should be changed and the oil tank and oil filter should be cleaned after the speed regulating hydraulic water ring vacuum pump runs for 500 hours for the first time. The oil quality shall be tested by visual inspection and laboratory test. When the oil quality deteriorates, the oil shall be replaced in time. 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.

In a short period of time when the liquid level drops, the bearing is lubricated by attached oil and splashing oil from plunger spring. The oil filter of oil tank and oil filter under pump are made of 230 mesh / inch copper wire mesh. The oil filter screen should be cleaned regularly to prevent blockage. When in use, the oil temperature of oil tank should not exceed 60 ℃, and appropriate measures can be taken to cool it if necessary.

After reading the above introduction, we can know that when using the vacuum pump, we should regularly drain the oil to prevent the oil from blocking the pipeline and affecting the use of the equipment.
