| Crankshaft oil seal sealing principle: | 1. Because there is an oil film controlled by the edge of the oil seal between the oil seal and the shaft, the oil film has fluid lubrication characteristics. Under the action of the liquid surface tension, the stiffness of the oil film just makes the oil film and the air contact end form a crescent surface to prevent oil leakage |
| Cause of oil spill | Generally, it is caused by the aging of the oil seal, but the aging of the oil seal may be more than 90% of the oil leakage is caused by the corrosion of the oil seal. Especially cars over three years old. Because the rubber seal will lose plasticizer under the influence of alternating temperature changes of cold and warm for a long time, the result is that the seal shrinks and stiffens and loses elasticity, and even breaks seriously (this degree is far from being reached, and the maintenance of oil leakage will be found), the oil leakage problem cannot be ignored. |
Crankshaft oil seal leakage has the following hazards:
1, the main harm of oil leakage is the loss of oil, resulting in
waste, serious may lead to insufficient oil, and then damage the
engine, not caused by oil leakage, but because the pressure after
oil leakage is not enough, so as long as you pay close attention to
the crankshaft oil seal, you can avoid the occurrence of this
situation.
