vacuum pump oil use precautions
How to choose vacuum pump oil was introduced before. But choosing the right oil also needs the correct use method, in order to maximize the performance of vacuum pump oil. So the vacuum pump manufacturer and you talk about the use of vacuum pump oil precautions.
1、 Storage of vacuum pump oil.
The container for vacuum pump oil must be clean, and it is strictly forbidden to store it in the sun or open air. The storage site should be kept dark, dry and low temperature, and moisture and mechanical impurities and dust should be strictly prevented.
2、 Loading and taking of vacuum pump oil.
When taking oil or filling oil, the dust around the cover of the container must be removed to prevent the impurities from mixing into the oil and causing friction with the internal parts of the pump.
3、 Vacuum pump oil mixed.
Different brands, varieties and new and old vacuum pump oil should not be mixed; at the same time, vacuum pump oil should not be mixed with other petroleum products, especially light oil, which will affect the vacuum performance of vacuum pump.
4、 Remove the special medium.
Vacuum pump to avoid pumping solvent, steam and corrosive gas. When this kind of medium gas must be removed, necessary remedial measures should be taken, and frequent inspection and oil change should be carried out frequently. Special attention should be paid to the timely exchange of new oil when the oil emulsion or dilution may affect the sealing performance of the pump.
5、 Replace the vacuum pump oil.
When changing the vacuum pump oil, the old oil must be drained completely, the new oil should be poured into the suction port of the pump, and the pump shaft should be turned slowly by hand to clean the pump cavity and drain the residual oil. Then the pump cavity should be cleaned several times, and then the residual oil in the pump shell should be cleaned and filled with new oil.
6、 Overhaul of vacuum pump.
When the vacuum pump is overhauled, all parts of the pump must be cleaned with solvent or cleaning agent and dried. During assembly, all parts must be impregnated with new vacuum pump oil before combination. After assembly, wash them again with new oil, and then add new oil.
In addition, vacuum pump oil filling appliances must be special equipment, not containers containing other oil or solvent. For the vacuum pump in strong corrosive environment or high cleanliness requirements, fluoropolyether oil can be selected according to the equipment requirements.
