Newly bought diesel generators with cylinder pulling failure? It may be caused by your improper use!

July 08, 2022
Diesel generator cylinder pulling fault refers to the piston and cylinder liner reciprocating movement between the location of the scratch, and the essence of the scratch is the loss of lubrication, metal and metal between the formation of dry friction. Generally speaking, the problem of cylinder pulling mostly occurs in some old units, such as long time not to clean up the carbon accumulation led to the reduction of the combustion chamber volume, the formation of a more serious heat load, there are some after the overhaul of the diesel generator set in the use of the process of poor handling, will also lead to cylinder pulling!

But when the newly bought diesel generator sets also appear to pull the cylinder failure, generally due to improper use of the user behavior and lead to.
 
1, the use of poor quality lubricants
 
For example, some users want to cheap with fake oil or refurbished oil, these poor quality oil is easy to intensify the wear and tear of the machine parts, resulting in high unit temperature and increase the sludge carbon, etc., is very likely to lead to the unit cylinder pulling phenomenon.
 
2, choose the wrong brand of lubricant
 
Wrong brand of lubricating oil and diesel generator models, the environment does not match, different environments, different models, the use of lubricant specifications are different, users should choose the right brand of oil according to the local season and temperature, and must pay attention to the oil quality level and viscosity level of these two indicators.
 
3, in the oil temperature does not meet the standard when pulling high speed (no problem when the low load, but the oil temperature does not meet the standard when pulling high speed risk).
 
4, diesel generator over-speed (or overload) operation.
 
5, diesel generator lubricating oil into the cooling water, resulting in poor lubrication.
 
6, diesel generator temperature is too high, resulting in poor cooling, resulting in cylinder liner and piston temperature is too high, resulting in overheating expansion, while the lubricant will fail due to high temperature, and then the phenomenon of cylinder pulling.
 
Diesel generator set cylinder pulling phenomenon will greatly affect the performance of diesel generator set, causing difficulties in starting the unit, power down, etc., affecting the normal power needs of users, so users must pay attention to avoid the unit pulling phenomenon.
