What role can lubricating oil play in bearing maintenance? What is the connection with bearing maintenance? First of all, the speed of movement: the higher the speed, the easier it is to form an oil wedge. You can choose low viscosity lubricating oil to ensure the existence of oil film. If the viscosity is too high, the resulting impedance will be large, the heat will be 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 fixations" and "three filters" of equipment lubrication work are effective methods to standardize and standardize the daily lubrication technology management work and ensure good equipment lubrication work.
Its contents are: five sets:
Appoint personnel: the work of the workers shall be determined. The lubrication workers shall divide the work of oiling, oiling, cleaning and changing the lubricating parts of the equipment, and take their respective responsibilities to complete the lubrication of the equipment together.
Bearing load: the higher the general load, the higher the viscosity of the selected lubricating oil. Low speed and heavy load should consider how large the oil load is.
Operating temperature: when the temperature difference is large, the oil with high viscosity index should be selected. When working at high temperature, the oil with high viscosity and flash point, good oiliness and anti-oxidation stability and corresponding additives should be selected. When the temperature is not high, low-temperature resistant oil with low viscosity, low water content and low freezing point shall be selected for operation.
Fixed point: determine the lubrication position and lubrication point of each equipment. Implement fixed-point oil supply.
Qualitative 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 pass the test.
Quantitative: determine the quantity of each refueling and oil change for the oil supply part, and implement the quota management of oil consumption and quantitative oil change.
Regular: determine the oil adding and changing period of each lubricating part, add oil, clean and change oil according to the specified period, and sample and test the oil tank with large oil storage capacity at regular intervals according to the regulations to determine the time and work content of the next maintenance.
Working environment: In the water and steam environment, it is necessary to pay attention to the selection of oil products with strong anti-emulsification, oil and rust resistance. In the dusty environment, it is necessary to pay attention to the dust seal. Some gases are corrosive, so oil with good corrosion resistance should be selected in this environment.
