What role can lubricating oil play in bearing maintenance? What is the connection with bearing maintenance?
The first is the movement speed: the higher the speed, the easier it is to form an oil wedge. Low viscosity lubricating oil can be selected to ensure the existence of oil film. If the viscosity is too high, the impedance is large, the heat is relatively large, and the temperature will be too high. When the running speed is slow, the load is carried by the viscosity of the oil, and the lubricating oil with higher viscosity should be selected.
"Five determinations" and "three filtration" of equipment lubrication are effective methods to standardize and standardize daily lubrication technology management and ensure good equipment lubrication. Its contents are as follows: five determinations:
Fixed person: the work of the workers shall be determined. The lubrication workers shall be responsible for the division of oil filling, oil adding, cleaning and oil changing of the lubrication parts of the equipment, and jointly complete the lubrication of the equipment.
Bearing load: the greater the general load, the higher the viscosity of the selected lubricating oil. The load of oil products should be considered for low speed and heavy load. c. Working temperature: when the temperature difference is large, the oil with high viscosity index shall be selected. Under high temperature conditions, the oil with high viscosity and flash point, good oiliness and anti-oxidation stability and corresponding additives shall be selected. When the temperature is not high, low temperature resistant oil with low viscosity, less moisture and low freezing point shall be selected for work.
Fixed point: determine the lubrication position and lubrication point of each equipment. Implement fixed-point oil supply.
Quality determination: determine the type, brand and quality requirements of the oil required for the lubricating parts of the equipment, and the quality of the oil must be tested and qualified.
Quantitative: determine the quantity of each refueling and oil change at the oil feeding part, and implement fuel consumption quota management and quantitative oil change.
Regular: determine the oil adding and changing cycle of each lubricating part, add oil, clean and change oil according to the specified cycle, and sample and test the oil tank with large oil storage capacity according to the regulations to determine the time and work content of the next maintenance.
Working environment: for water vapor environment, it should be noted that oil products with strong demulsibility, good oil and rust resistance should be selected, and dust-proof sealing should be paid attention to in dusty environment. Some gases are corrosive. Oil with good corrosion resistance should be selected in this environment. ④ "Five determinations" and "three filtration" shall be done well in lubrication work
