1, master and identify the basic knowledge of fake and inferior products, and purchase high-quality and standard oil seals.
2. When installing, if the outer surface roughness of the shaft diameter is low or there are rust spots, rust, burrs and other defects, it is necessary to use fine abrasive cloth or oilstone polishing smooth; in the oil seal lip or shaft diameter corresponding position coated with cleaning oil or grease. Coat the outer ring of the oil seal with sealant, wrap the key slot on the shaft with cardboard, avoid scratching the lip of the oil seal, rotate and press the oil seal inward with special tools, and never strike hard to prevent the oil seal from deforming or breaking the spring and failure; if lip flanging, spring shedding and oil seal deflection must be removed and reinstalled. . It should be noted that when the shaft diameter is not worn and the oil seal spring is elastic enough, do not tighten the inner spring without authorization.
3. When the oil seal used in machinery is in bad working conditions, big ambient temperature difference, dusty and frequent vibration of the machine makes the mechanical condition of the machine constantly changing, it should be inspected, maintained and maintained frequently.
4. If shaft diameter and bearing wear seriously; oil seal rubber aging or spring failure, should be timely repair and replacement of the corresponding components.
5. Troubleshooting the abnormal heating parts or assemblies in time; Avoiding mechanical overspeed and overloaded operation to prevent lip temperature rising, rubber aging, lip early wear and tear etc.
6. Always check the oil level. If there are too many impurities in the oil, replace the oil thoroughly when there are alloy powder and metal iron scraps. The brand and quality of the oil should meet the seasonal requirements. It is suggested to add Metre super sealant-lubricant in engine oil. It is an excellent additive for gearbox. It can form a film of inert material on parts. It can slow down the leakage of oil seal, prolong the service life of oil seal gears and reduce the noise of gearbox. This Metre super sealant lubricant can also reduce the noise of gearbox. Use will not cause oil pollution or oil deterioration.
Instructions for use:
(1) when the lubricating oil volume of the reducer is less than 7 liters, the lubricating oil content per liter is 20 to 30ml.
2. When adding 7 to 15 liters, the adding amount is 15 liters of 20ml per liter of lubricating oil.
3. When >15 rises, add 10ml to the litres of lubricating oil.
7, temporarily do not use the oil seal, should be properly kept, to prevent oil stains, dust or sun exposure.
8. When the shaft diameter is worn into a V-shaped groove, so that the new seal lip and shaft contact pressure drop can not seal oil, displacement method can be used to make up.
