Discussion on the main reasons of burning tile in diesel generator

Burning tile is the tin alloy layer of the diesel engine spindle tile or connecting rod because of the deterioration of smooth conditions, and the journal dry conflict with high temperature surface melting, and the crankshaft journal attack sintering. The performance of the fault attack is: the engine takes black smoke, the oil pressure drops, presents a significant sense of exertion, the speed drops quickly, the crankcase vent takes white smoke, and announces that 'haw' has dry conflict sound. At this time, if you do not stop in time, the situation will rapidly deteriorate to form bearing and journal bonding, repair more difficult.

Sand and metal chips into the oil channel caused by burning tile, oil pump damage caused by oil supply stop, bearing bush quality is unqualified, journal and bearing bush with changes, oil channel blockage, lubricating oil sent to the friction place, insufficient oil principle will cause burning tile, oil leakage is an important cause of insufficient oil pressure.

Not using the right oil. Different grades of lubricating oil should be used in different seasons. Some diesel generator burning tile, is because of the summer use of small viscosity lubricating oil, the formation of oil film on the bearing surface.

Chronic overload leads to tile burning. Because of long-term overload operation, the diesel generator set temperature is high, the speed is low, the bearing capacity of the bearing bush is increased, the oil supply of the oil pump is reduced correspondingly, and the oil viscosity is reduced at high temperature, it is easier to cause burning tile.

The oil level is too low, the suction air surface can not supply oil, if the oil pressure is not found in time, continue to drive, will immediately cause burning tile.

Oil deterioration, oil deterioration is usually due to cooling water. Fuel leakage into the oil pan caused by, in addition, the fuel injector atomization is poor, the engine often boom throttle, will also cause the diesel engine can not be completely burned, cause oil deterioration.

Other reasons such as the wrong use of oil, often overload caused by excessive load or oil pressure limiting valve bolt tightening, resulting in excessive oil pressure, long-term low load operation may also burn watts, so, in the use and maintenance of diesel generator set should be avoided, in order to reduce the occurrence of failure.
