Screw vacuum pump is a device to improve, produce and maintain vacuum in a closed space by various methods. According to the working principle of vacuum pump, it is widely used in metallurgy, chemical industry, food, electronic coating and other industries. The correct use of vacuum pump oil is very important for the normal operation of screw vacuum pump. The following section will tell you about the use of vacuum pump oil cleanliness problems and Countermeasures:

1. The oil loading window must be clean. It is strictly forbidden to expose it to the sun and open air. It should be stored in dark, dry and ventilated places to prevent moisture and dust from mixing in.

2. Oiling appliances must be special equipment, not containers containing other oil or solvent.

3. When taking oil or filling oil, the impurities around the barrel cover must be removed to prevent the impurities from mixing into the oil and causing pump wear.

4. When changing the oil, the used oil in the pump body should be drained. After the new oil is poured into the pump, slowly rotate the pump shaft, clean the pump cavity, drain the residual oil, repeatedly clean it for several times, and then replace the new oil after cleaning.

5. When mineral oil is exchanged with ester oil or other synthetic oil, the vacuum pump should be disassembled for thorough cleaning. All parts must be dipped in ester oil to prevent contamination.

6. When the screw vacuum pump is overhauled, all parts of the pump must be cleaned with solvent or cleaning agent and dried.
