Harm of Slamming The Throttle After Cold Start The Generator Set

Nov. 20, 2023

After the generator set is cold started, it is not allowed to slam the throttle. As the generator set is shut down without waiting for speed and temperature reduction, the oil content on the friction surface will be insufficient. When the diesel engine runs again, it will be further damaged due to poor lubrication.

After the generator set shuts down, the circulation of the cooling system water is terminated, and the heat removal capacity is greatly reduced. When encountering hot parts, the cooling is lost, which can easily cause overheating of parts such as the cylinder head, cylinder liner, and cylinder liner, causing cracks, or causing the piston rod to swell too much and get stuck in the cylinder liner. On the other hand, if the generator set is shut down without waiting for speed and temperature reduction, it will result in insufficient oil content on the friction surface. When the diesel engine runs again, it will be further damaged due to poor lubrication. Therefore, before the generator unit shuts down, it is necessary to unload the load and slowly reduce the speed ratio, and run at full load for a few minutes.


If the accelerator is slammed, the speed ratio of the generator set will increase significantly, which will cause some friction surfaces inside the machine to be severely damaged due to dry friction. In addition, when the throttle is hit, the piston rod, crankshaft, and engine crankshaft undergo a significant change in force, causing strong collisions and easily damaging parts.


When the refrigeration machine of the generator set is started, due to the high viscosity and poor flowability of the diesel generator oil, the oil provided by the fuel injection pump is insufficient, and the friction surface of the equipment is not well lubricated due to insufficient oil, resulting in significant damage, and even common faults such as engine cylinder pulling and shoe bursting. Therefore, after the diesel engine is refrigerated and running, it should wait for the engine to run at high speed and raise the temperature, and then run with load when the oil temperature reaches above 40 ℃; Equipment development should shift to low gear and drive for a certain mileage in each gear in sequence until the water temperature is normal and the provided oil is sufficient, and then all normal driving can be achieved.


When the generator set runs low on oil, it may cause abnormal damage or burns due to insufficient oil supply on the surface of each friction pair. Therefore, before the development of generator sets and during the entire process of diesel engine operation, it is necessary to ensure that there is sufficient engine oil in the car to avoid common faults such as engine cylinder pulling and bearing failure caused by insufficient oil.
