Oil seal leakage solution summary

Seal is the abbreviation of "Seal of Lubricating Oil". Its function is to isolate the parts that need to be lubricated in the transmission parts from the output parts so as not to let the lubricant leak. That when the seal lost its effect, failure and leakage of time to how to do it?

1. Grasp and identify the basic knowledge of counterfeit products, buy high-quality, standard oil seal.

2. Installation, if the shaft diameter of the outer surface of the low roughness or rust, rust, burrs and other defects, with a fine sand cloth or whetstone polished smooth; oil seal lip or shaft corresponding position coated with a clean oil or grease. Oil seal outer ring coated with sealant, cardboard with keyway parts of the shaft wrap up to avoid scratching the seal lips, with special tools will be pressed into the oil spin inside, do not hard hit hard punch to prevent deformation of the seal Or squeeze the spring failure; if there is lip flanging, spring off and oil seal skew must be removed and re-loaded. It should be noted that: When the shaft diameter is not worn and the oil seal spring elastic enough, do not tighten the inner spring without permission.

3.Applied to the mechanical seal on the general poor working conditions, environmental temperature, dust, frequent vibration of machinery parts force constantly changing conditions, to ground inspection, maintenance and repair.

4. If the shaft diameter and bearing wear serious; seal rubber aging or spring failure, etc., should promptly repair and replace the corresponding parts.

5. For parts or assembly of abnormal fever should be promptly troubleshooting; Avoid mechanical speeding, overload operation, in order to prevent the oil seal lip temperature, rubber aging, lip wear early and so on.

6. To always check the oil level, if the oil impurities too much, there are alloy powder, metal scrap iron to completely replace the new oil. Change the oil brand and quality to meet the requirements of the season. It is recommended to add Mettler Super Sealant & Lubricant to the engine oil, an excellent gearbox additive that forms an inert material film on the part that slows the leakage of the oil seal and extends the use of the oil seal gear Life expectancy also reduces gearbox noise and the use of this Metteler super seal lubricant will not contaminate or degrade the oil.

User guides:

① reducer lubricant volume ≤ 7 liters, the amount of lubricant per liter for the 20-30ml;

② 7-15 liters, the amount added per liter of lubricant add 15-20ml;

③> 15 liters, the amount added per liter of lubricant add 10ml.

7. Temporarily unused oil seal, should be properly stored to prevent contamination with oil, dust or sun exposure.

8. When the shaft diameter worn into a "V" shaped groove, so that the new oil seal lip and shaft contact pressure drop can not play the role of seal oil, the displacement method can be used to make up.
