Why the generator set pull the cylinder and the characteristics of the cylinder after the pull

Date:2019-06-06

Piston, piston ring and cylinder liner work appearance is destroyed. The consumption of oil and the amount of channeling gas increased rapidly, gas seal failure. So that the engine can not work properly, even in a very short period of time, due to the piston, piston ring and cylinder liner and stop ... ... ... ...

 

Diesel generator set cylinder failure characteristics:

1. The external characteristics of the diesel generator set after the cylinder is the sound changes, exhaust smoke black smoke.

2. Piston, piston ring and cylinder liner work appearance is destroyed. The consumption of oil and the amount of channeling gas increased rapidly, gas seal failure. So that the engine can not run normally, even in a very short period of time, due to the piston, piston ring and cylinder liner killed and shut down.

 

Diesel generator set cylinder failure reasons:

1. The main reason for the diesel cylinder is actually the piston, piston ring and cylinder liner appearance due to high temperature and "welding" strain. That is, between the piston and the cylinder liner due to oil film interruption occurred dry friction. And the nearby metal particles torn off. The hot frictional heat causes the metal to melt and stick.

2. The most fundamental reason for the diesel cylinder is the oil film interruption. According to the requirements of gas seal. This makes it very favorable for lubrication conditions. The gap between the piston ring and the cylinder liner should be as small as possible due to contact appearance overload. So that the appearance of the cylinder liner and the piston ring surface due to direct contact between the violent friction, a lot of friction heat, so that the surface temperature of a sharp rise, the consequences of two friction welding surface adhesion caused by injury. Thus visible. The channeling is serious and the fuel supply is bad. Parts of the contact stress is too large to damage the oil film, resulting in diesel generator sets the main reason for the cylinder. In addition to lubrication, with the gap, parts manufacturing quality, the use of improper use may also cause diesel generator cylinder failure, specifically the following:

1. Piston and cylinder liner with the gap is too small. Such as small gaps, thin oil or oil in the assembly without oil.

2. Poor lubrication.

3. Diesel engine overheating.

4. When the assembly is not clean or the piston is too dead.

5. Poor piston and piston rings.

From the perspective of use. Before starting the best crank with the crankshaft turn a few laps, but also pay attention to try to prevent sudden increase in load or emergency stop. So that the appearance of friction to adhere to a certain amount of oil.
