Burning tile is diesel engine spindle tile or connecting rod tin alloy layer because of the deterioration of smooth conditions, and the journal dry conflict attack high temperature surface melting, and the crankshaft journal attack sintering. The performance of the attack is: the engine smoke, oil pressure drop, showing a significant sense of effort, the speed of agile decline, the crankcase vent smoke white, and announced that ‘chirp’ have dry conflict sound. At this time, if the machine is not stopped in time, the situation will rapidly deteriorate to form the bearing and the shaft neck binding, and the repair is more difficult.
Sand particles and metal chips into the oil channel caused by burning tile, oil pump damage caused by oil supply, bearing bush quality is not qualified, the change between the journal and bearing, oil blockage, lubricating oil can not be sent to the friction place, oil principle will cause burning tile, oil leakage is an important reason for oil pressure shortage.
Not using lubricating oil correctly. Different grades of lubricating oil should be used in different seasons. Some diesel generator burning tile, is due to the use of small viscosity lubricating oil in summer, in the bearing contact surface can not form the oil film.
Burning tile caused by prolonged overload. Because of long-term overload operation, the diesel generator set has high temperature and low speed, the bearing capacity of bearing bush increases, the oil supply of oil pump decreases correspondingly, and the oil viscosity decreases at high temperature, which is more likely to cause burning tile.
The oil level is too low, and the suction air surface can not supply oil. If the oil pressure is not found in time and the car continues to drive, it will immediately cause burning tile.
Oil deterioration, oil deterioration is generally due to cooling water. Fuel leakage into the oil pan caused by, in addition, the injector atomization is not good, engine work often bang throttle, will also cause the diesel engine can not fully combustion, cause oil deterioration.
Other reasons such as the wrong use of oil, often overload caused by excessive load or oil pressure limiting valve bolt is too tight, resulting in oil pressure is too large, long-term low load operation may burn tile, therefore, in the use and maintenance of diesel generator set should pay attention to avoid, in order to reduce the occurrence of failure.
Jiangsu Meiao Power Technology Co., Ltd. is an important manufacturer of diesel generators. Us ao-generator set manufacturers mainly manufacture and sell diesel generator sets, the power of generator sets is 3-3000KW, mobile station is 24-600KW, Marine emergency diesel generator set 24-800KW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, silent speaker, mobile lighthouse, container, etc.) diesel generator Group at the same time engaged in generator set maintenance and generator set accessories after-sales service.
