Speaking of standby diesel generators, it is to "Maintain an army for a thousand days to use it for an hour." Therefore, most of the spare diesel generator sets are spared after being purchased. If the mains supply is normal, the diesel-diesel generator set is basically unused and is in a long-term idle state.
The piston generator top clearance is too large. If the diesel engine is overhauled, the diesel engine piston top clearance is not checked and adjusted in strict accordance with the requirements, or the excessively thick diesel generator cylinder head gasket is selected to make the piston top clearance larger, which will increase the space of the diesel engine combustion chamber. This directly affects the compression ratio of the diesel generator and thus the cylinder pressure.
Excessive water temperature is one of the most common failures of diesel water-cooled type. Due to the different thermal expansion coefficients of the cylinder sleeve and piston friction pair material, the high temperature will make the gap smaller, the lubrication condition will deteriorate, and the cylinder and piston ring will be stuck for a long time.
When we purchase and select diesel generator sets, they often confuse the relationship and definition between apparent power, active power, rated power, maximum power and economic power. For this reason, we have sorted out the relationship between them so that everyone can understanding.
