How to cause the cooling fan to leak oil

Release time:

2019-11-06

1. The oil supply to the bearing box is too high. The smoothing oil is supplied from both sides of the bearing housing. The bearing box is equipped with an oil ring, and its flow is controlled by the oil supply throttle valve. If the supply flow of the cooling fan is too high, the heat of the fan will be affected by the high-speed operation of the rotor and the smooth increase of the oil temperature, which will inevitably cause the maximum oil level limit to be lower than the actual oil level. bearing housing, resulting in oil seal leakage. In addition, too high a smooth oil pressure will also lead to shaft seal leakage. 2. The sealing of the pipeline interface is not strict, and the most likely part of the bearing box is the shaft seal. If the O-ring and the skeleton oil seal of the cooling fan shaft seal are worn, aged, and during maintenance

Cooling fanEnglish name: Cooling fans. Cooling fan, English name: cooling fan. The technical and performance aspects of cooling fans have reached a mature stage, and new technologies continue to appear. However, many people find that oil leaks are usually caused by cooling fans. Although this does not happen often, the cooling fan itself is not a big problem, but it also wastes resources. After all, engine oil is also expensive, so in order to prevent this, we must always maintain the cooling fan. The little braid takes you to understandCooling fanThe cause of the oil spill.
1. The oil supply to the bearing box is too high. The smoothing oil is supplied from both sides of the bearing housing. The bearing box is equipped with an oil ring, and its flow is controlled by the oil supply throttle valve.

In addition, too high a smooth oil pressure will also lead to shaft seal leakage.
2. The sealing of the pipeline interface is not strict, and the most likely part of the bearing box is the shaft seal. This can happen if the O-ring and skeleton oil seal of the cooling fan shaft seal are worn, aged, and the assembly process is incorrect during maintenance.
3. The hydraulic cylinder leaks oil. The cooling fan hydraulic cylinder is not tightly sealed or the gap is too large. If it is not tightly combined, the hydraulic cylinder may leak oil.
4. The quality of lubricating oil is unqualified. Certain oil quality timing tests were not conducted in accordance with the rules. Excessive particle size will cause the rubber gasket to wear, or the moisture in the smooth oil will cause the servo valve to rust and damage, resulting in oil leakage.
The above is the common ground of the cooling fan oil leakage.
