Today, I would like to share with you the causes of cylinder liner strain of diesel generator sets, which are as follows:
Diesel engine cylinder liner strain and abrasion phenomenon refers to the appearance of some uneven, irregular groove and wrinkles on the inner wall of the cylinder liner, which is abnormal wear.
First, the main reasons for cylinder liner strain and cylinder liner abrasion are as follows:
1. The early run-in of diesel engine is not good, and the oil is not changed according to the technical requirements;
2. The clearance between piston and cylinder liner is too small in the assembly process;
3. The assembled piston ring incision clearance is too small;
4. Did not replace the seasonal oil as required, resulting in poor lubrication of the inner wall of the cylinder liner;
5. If the air entering the combustion chamber is too dirty, the use of diesel can not be purified, and the internal impurities of the oil are too much, the inner wall of the cylinder liner will appear abnormal wear.
Two, cylinder liner strain or abrasion inspection method:
When the inner wall of the cylinder liner of the diesel engine is seriously pulled or bruised in the process of operation, the speed of the diesel engine will decrease significantly, that is, the specified oil supply can not reach the rated speed of the diesel engine, the smoke is blue, black, stop the diesel engine operation, if the fly ring of the diesel engine, you will hear the sound of leakage inside the crankcase.
Jiangsu Meao Power Technology Co., Ltd. is an important manufacturer of diesel generators. The company mainly manufactures and sells diesel generator sets with power of 3-3000kW, mobile power station of 24-600kW, Marine emergency diesel generator set of 24-800kW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, static speaker, mobile lighthouse, container, etc.) diesel generator At the same time, we are engaged in generator set maintenance and after-sale service of generator set accessories.
