Answer: In addition to improper selection or use of lubricating oil, lubrication accidents are mainly caused by pollution. Substances that pollute lubricating oil include dust, impurities and moisture. The pollution of lubricating oil can be controlled from the following aspects:
(1) The containers for storing and transporting lubricating oil must be clean and sealed, and must not come into contact with metals such as copper and tin that are easy to promote the oxidation and deterioration of lubricating oil.
(2) The refueling container must not be exposed to the atmosphere, especially the oil container must not be uncovered.
(3) A filter with a mesh size of more than 100 and a dust cap should be installed at the refueling port.
(4) The oil and gas barrels storing lubricating oil should be cleaned regularly and the sewage should be discharged in time.
(5) An air filter is installed at the inlet of the air compressor. The air filter must be installed tightly and the cleaning must be carried out in accordance with the requirements.
(6) Filters and drain valves are installed at appropriate parts of the lubrication system.
