How is the new diesel generator set commissioned?
Newly purchased diesel generator sets need to be debugged, so do you know how the diesel generator sets should be debugged? The following will introduce you in detail:
The diesel generator set debugging content can be divided into two parts: no-load debugging and load debugging
Unit no-load commissioning
After the newly purchased diesel generator set is positioned, the exhaust pipe is installed, and the coolant is connected to the lubricating oil, the power line is first connected to the unit for no-load commissioning. After the unit is started successfully, the engine oil pressure is 1-2 minutes after idling. Normal, there is no abnormal sound of the unit. When the frequency of the unit fluctuates, it rises to a high speed to 1500 rpm rated speed. Observe the various measuring instruments of the unit, the frequency is 50HZ, the voltage is 400V and the three-phase balance, the power generation indicator lights up, and the engine oil pressure is not lower than 2MPa. The unit has no abnormal sound, no oil leakage, air leakage, or leakage of cooling liquid, and the unit control switch is closed freely. The unit's ground wire is securely connected, the power line is correctly connected, and the color marking is clear and correct.
Unit load debugging
On the basis of no-load commissioning, close the control switch and slowly increase the unit from a small power load to the unit's rated power. During the load test, observe whether the unit has abnormal vibrations and abnormal sounds. If there is an abnormal situation, press the emergency stop button to take an emergency stop. Observe how the voltage fluctuates when the load increases, the voltage fluctuation rate is 5% in the normal range, whether the frequency is guaranteed to run above 50HZ at the rated power, whether the color of the engine exhaust smoke is abnormal, and whether the oil pressure and water temperature are within the specified values. The three-phase voltage of the unit not only needs to be balanced, but also needs to be balanced when three-phase current is running.
After the above steps, there is no abnormality before the diesel generator set can be put into use. Please read the instructions before use to operate the new unit correctly and safely.
