Our approach bearing knowledge oil seal leak

       Seal is an important part on the various types of agricultural machinery and equipment, widely used. Tractors, farm vehicles, rice combine harvesters and other farm machinery are equipped with a variety of seals, which can effectively prevent leakage of lubricating oil, hydraulic oil, to prevent dust, dirt into the machine. Seal performance and quality is good or bad, a direct impact on the reliability of agricultural machinery and equipment of all kinds. 1 year seal long life, short of only a few months or even three days. Mifengbuyan caused as a result of oil spills and scrap, it will seriously affect the efficiency of various farm equipment, which not only increase fuel consumption and production costs, but also pollute the environment. Used oil seal leakage caused by hand should be aware of the causes and coping methods.

First, the main reason for the oil spill caused by farm machinery seal

1. New or Used overhauled, not strictly in accordance with the technical regulations after running-operation and running maintenance jobs, down from the grinding swarf into the seal inside the machine, the produce abrasive wear, leading to seal early damage.

2. When installing seal not clean, impurities and dust into the seal, causing the seal to produce accidental wear.

3. Install, machine hand knowing machine shaft has visible scratches and glitches, still the seal loaded into the machine, resulting in seal strain; or oil and machine shaft with tight enough, causing oil seal leak.

4. There are obvious defects, aging, crack seal is mounted on the machine, resulting in oil seal leak.

5. operations when improper assembly, resulting in seal distortion, and even lead to self-tight seal spring shedding, causing loss of oil spills.

6. Seal self-tightening spring force is not enough, poor sealing, resulting in oil spills.

7. Used frequently speeding, resulting in the installation of the rotary shaft seals operating speed than the adaptation of seals, which led to oil seal leak.

8. The shaft seal is installed in the machine is not positioned correctly, such as when the skeleton since the tight seal and rubber seal skeleton small tractor mounting position opposite the drive shaft, or skeleton since the tight seal of the opening to the anti-loaded, causing oil spills; Again Seal the machine shaft is installed incorrectly, causing the centerline of the centerline of the shaft seal do not coincide, and produce oil spills.

Second, the solution method to deal with farm machinery oil seal leak

1. Master and basic knowledge to identify counterfeit products, to buy high-quality, standard seals.

2. Before installation, if the outer surface of the machine journal rough or rust, corrosion, since burrs, use a fine emery cloth or Whetstone polished smooth; oil seal lip or journal in corresponding positions Apply clean oil or grease; oil seal outer coat sealant, with cardboard machine shaft portion of the keyway wrap, avoid scratching seal; for lip seals to use special tools to press forward in the rotation, you do not hit hard red hard to prevent Seal off the spring deformation or extrusion and failure; if there is lip flanging, spring off and seal skew, you must remove the reload. It should be noted that when there is no wear and seal machine journal spring force enough, do not arbitrarily tighten the inner spring.

3. Apply in mechanical seals, generally poor working conditions, environmental temperature, dust and more frequent machine vibration, mechanical stress and makes changing status, so to ground inspection, ground maintenance and ground maintenance.

The machine journal and bearing wear serious, seal rubber aging or spring failure, should be timely repair and replacement of the corresponding parts.

5. abnormally hot parts, should be lifted failure, avoid mechanical overspeed, overload, to prevent the oil seal lip temperature, rubber aging, early lip wear.

6. Always check the oil level and oil quality status, if the oil level is too low or too many impurities, when there are alloy powders, metal scrap, to completely replace the old oil, the oil change grades and quality to meet the season Claim.

7. temporarily without seal should be properly safeguarded to prevent seal oil stains, dust, or exposure to sunlight.

8. When the machine journal wear 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 choice of AR-5 two-component adhesive sticky patch, In this way, simple and reliable and wear; seals shift method can also be used to compensate.
