1, lead to diesel generator sets appear oil level increase reason:
1.1 fuel oil leakage into the machine
Plunger injection pump for generator wear is too large, the injector needle is not tightly closed or needle stuck in the open position; the clearance between the piston and the piston ring and cylinder is too large, so that the fuel leakage along the cylinder wall to the oil pan.
1.2 water infiltration generator oil basin
Cylinder gasket destroyed; crack and the wall of the cylinder jacket figured; wet liner and the cylinder block between the rubber sealing ring is not installed properly or damaged.
2, diesel generator set oil surface caused by the fault:
2.1 blue smoke exhaust.
2.2 big splash of oil.
2.3 engine running weakness.
3, processing method:
First draw the oil gauge to check whether the oil is too thin. If the oil level is found to increase and very thin, should further find reasons to see if there is water or fuel leakage and dilute the oil, causing too thin. Its inspection methods are as follows:
3.1 out of the oil measurement and a few drops of oil on paper to observe the oil color and smell, such as oil, yellow milk color, and no other smell, that is water entering the crankcase, should check the cylinder pad is washed out, the cylinder is installed correctly if there is water, wet or damaged cracks between the liner and the cylinder block rubber sealing ring.
3.2 if you smell a smell of fuel oil, the engine should be started to observe whether the operation is good. If you start the diesel engine exhaust smoke, should check whether the injector needle valve normally closed, if there is leakage, maintenance should be.
3.3 if the engine at normal operating temperature under insufficient power, should check the fuel pump plunger vice whether leakage (for diesel gasoline engine, it should check the gasoline pump skin is broken), with the gap between the piston and the piston ring and the cylinder is too large, and for replacement or repair.
3.4 check and repair after the completion of the old oil must be released, and clean the lubricating oil system, and then add the appropriate amount of new oil brand.
3.5 when the diesel generator sets in the use of the process, there should be dedicated guards, always concerned about the various changes in generating units, in case of accidents.
