Causes of Compression Leakage in 100kW Volvo Generator

When a diesel generator starts or rotates, a "beep" sound indicates that the cylinder is leaking during compression. Many people do not understand the causes of cylinder compression and leakage in diesel engine generators. Below, based on the introduction from Dingbo Power Generator Manufacturer, we will introduce the causes of compression and leakage in 100kW Volvo generators, which mainly include the following points:

1.The cylinder head gasket is broken, leading to air leakage. If there is soot on the damaged port, the cause should be determined after using the gasket. If the cylinder head bolts are loose, the cylinder liner will protrude from the plane regardless of whether it is a normal cylinder liner or not. If the protrusion amount is uneven, it should be arranged to protrude in the vehicle body according to the order of quantity, or it can be optional. At the same time, during maintenance, attention must be paid to the clean planes of the vehicle body and cylinder head. Accumulated carbon, scale and other debris on the accumulated surface should be removed, and then cleaned with fine gauze. The tightening of cylinder head bolts should be carried out according to the tightening principle.

2.The copper washer of the injector hole seal ring is damaged, deformed, and the pressure plate is loose. There are debris such as carbon deposits on the sealing surface of the cylinder head hole, resulting in poor sealing.

3.When there is a "sound" leakage sound in the intake and exhaust pipes, the low-speed phenomenon is more obvious. This may be the leakage of the intake valve and exhaust valve. Check the causes of leakage: such as the sealing cone on the valve and valve seat. Eclipse, too wide belt, foreign objects stuck on the cone, poor sealing, excessive carbonization of the valve guide rod, valve stem biting the guide tube, broken guide tube, severe wear of the guide tube, broken valve spring, too weak valve spring, and if the valve clearance of Weichai generator set is too small, valve leakage may occur.

The above are the three main causes of compression and leakage in 100kW Volvo generators. We believe that if your generator has the above problems, you will find a solution. Of course, if you want to buy a diesel engine, please contact us, and we look forward to your visit.
