Why Did the Diesel Generator Appeared Burning Watts

Oct. 15, 2021

Diesel power generation units occasionally cause bush burning, that is, the rolling bearing of the diesel engine is damaged. In the case of diesel generator burning problems, black smoke may be generated, the oil pressure is greatly reduced, movement is weak, and the crankcase White oily smoke from the air vents, and there are problems such as "chicking" and clashing sounds. In this case, what is the actual cause of the burning problem of the diesel generator set? This article is summarized by Dingbo Power for everyone.

 

1. Lubricating oil is not used according to the time period. Different grades of lubricating oil should be used for different time periods. Some diesel engines burn bushes, which is caused by the use of low-viscosity lubricating oil in summer, which causes no oil film on the bearing bush contact surface.

 

2. The lubricating oil is not clean. If dirty lubricating oil is added to the body, it will block the oil circuit and cause tile burning.

 

3. The addition of engine oil is inappropriate. If the engine oil is too much, the diesel engine will burn the engine oil very easily and produce carbon deposits. Generally speaking, it is more suitable for the oil level to be in the middle of the upper and lower scales of the oil dipstick.

4. Do not pay attention to check the meter. When the diesel engine is running under normal conditions, the oil pressure should be in the middle of (0.15~0.25) MPa, and the oil pressure at idle speed should not be less than 0.5 MPa. Some customers don't pay much attention to the oil pressure gauge, so that they can't find and deal with the hidden safety hazards in time.

 

5. The coordinated distance between the shaft and the tile does not meet the requirements. If the distance is too small, the oil is not so easy to enter, and the oil film layer cannot be produced. If the distance is too large, the oil is very easy to flow out, and the oil film layer is also difficult to produce. Therefore, when repairing and assembling, it is necessary to ensure that the spacing between the bearing bushes is within the scope of the standard.

 

6. Burning tiles caused by long-term high-load operation. Due to long-time high-load operation, the diesel engine has high temperature and low rotation speed, the bearing capacity of the bearing is improved, and the oil supply of the oil pump is correspondingly greatly reduced. In addition, the viscosity of the oil is greatly reduced at high temperatures, which is more likely to cause burns watt.

 

The above is the reason why the bush burning problem of the diesel generator set is very likely to occur. When the generator set has a problem, the customer should stop it for maintenance immediately, otherwise it may aggravate the problem drastically and cause the bearing bush and the journal to stick and lock. , Resulting in an increase in the difficulty of maintenance management.
