Application of Lubricating oil in Bearing Maintenance
What is the main role of lubricating oil in the maintenance of bearings? What is the relationship to the maintenance of bearings?
The first is the speed of motion: the higher the speed, the easier the shape of the oil wedge, you can choose low viscosity lubricating oil to ensure the existence of the oil film. Choose viscosity is too high, it will produce a large impedance, heat is relatively large, will lead to high temperature. Running speed is slow, depending on the viscosity of the oil to carry the load, should choose a higher viscosity of the oil.
The "five fixed" and "three filtration" of equipment lubrication work are the effective methods to standardize and standardize the daily management of lubrication technology and ensure good equipment lubrication work. Its content is "Wuding" :
1. Appointment: the work of the workers shall be determined, and the lubricators shall divide the work of refueling, oil filling, cleaning and oil changing at the lubricating parts of the equipment, and take their respective responsibilities to jointly complete the lubrication of the equipment.
Load: the larger the load, the higher the viscosity of the lubricating oil. Low speed heavy load should consider the load of oil products. C. Operating temperature: Oils with high viscosity index should be selected when the temperature difference is large; oils with high viscosity and flash point, oil and good antioxidant stability, and corresponding additives should be selected when operating under high temperature conditions. When the temperature is not high, the work should choose viscosity low water less, low freezing point of low-temperature resistant oil.
2. Fixed point: determine the lubrication position and lubrication point of each equipment. Implement designated oil feeding.
3. Quality determination: determine the type, brand and quality requirements of the oil required for the lubricating part of the equipment. The added quality must pass the test.
4. Quantification: determine the amount of oil changing for each refueling of the oil position, implement fuel consumption quota management and quantitative oil changing.
5. Periodic: determine the cycle of oil adding and changing for each lubricating part, refueling, filling, cleaning and changing oil according to the prescribed cycle. For oil tanks with large oil storage capacity, sample and test in the prescribed cycle, and determine the time and work content of the next maintenance.
Working environment: Water vapor environment should pay attention to the selection of strong anti-emulsification, oil and rust resistance oil products, dust environment should pay attention to dust seal. Some gases are corrosive. In this environment, oils with good corrosion resistance should be selected. Lubrication should be done "five fixed" "three filtration".
