Loaders will inevitably encounter failures in use. A common fault is that the engine in the loader accessory burns out the bearing bush. Quite a few people think that the main reason for the burned bearing bush is the oil pump. Let’s introduce four reasons:
1. The quality and brand of the engine oil do not meet the requirements of engine lubricating oil, or it is improperly stored. The engine oil has deteriorated due to water ingress and loses its lubrication function.
2. The lubricating oil circuit of the engine is blocked. Especially, the oil path leading to the bearing bush is blocked by impurities and sludge, which causes the oil path to be blocked, lose lubrication and burn the shaft
3. The oil temperature is too high, the oil becomes thin, the oil pressure drops, the lubrication is poor, and the bearing bush is burned out.
4. Insufficient supply of lubricating oil. The engine lubrication system is short of oil, and it is difficult to form a lubricating oil film between the bearing bushes. The lubrication is not good. The shaft and the bushes are in direct contact and friction, and the temperature rises sharply. At the same time, lack of oil in the engine lubrication system will also cause damage to the oil pump.
Therefore, after encountering engine failures, specific problems must be analyzed in detail to find feasible solutions.
