Reasons for Damage Relevant Parts of The Cummins Diesel Generator Set

Before start the Cummins diesel generator set, it must be check the cooling water or antifreeze in the water tank whether it meets the requirement. Pull out the oil dipstick to check whether the lubricating oil is lacking, if yes, you need to add it to the specified "static full" scale line. Then carefully check the relevant parts of the Cummins diesel generator set if any hidden troubles. If the trouble was found, it must be removed in time before it start the diesel genset. Before starting the Cummins diesel generator set, pay attention to the output air switch of the Cummins diesel generator set must be in the closed state. Before start the Cummins diesel generator set, pay attention to the output air switch of the unit must be closed. After started the Cummins diesel generator set, the first you need to observe is whether the oil pressure is normal and whether there is any abnormal phenomenon such as oil leakage or water leakage. Not allow long time no-load operation.

Because the long time no-load operation will make the diesel fuel sprayed by the Cummins diesel generator set fuel injectors can not be completely burned, resulting in carbon deposits, causing valve and piston ring leaks. If it is an automated Cummins diesel generator set, it does not need to run at idle speed, because the automated Cummins diesel generator set is generally equipped with a water heater, so that the cylinder block of the Cummins diesel generator set is always maintained at about 45°C. The Cummins diesel generator set can be operated at 8 Normally power on within -15 seconds. Cummins diesel generator sets must have a dedicated person on duty during work, and always pay attention to a series of possible failures. If the fuel is interrupted during the operation of the Cummins diesel generator set, it will objectively cause a load stop, which may cause damage to the excitation control system and related components of the Cummins diesel generator set.

Before starting the Cummins diesel generator set, you must carefully check whether the wiring of each part is correct, whether the brushes are normal, whether the pressure meets the requirements, and whether the grounding wire is good. Before starting, put the resistance of the excitation rheostat at the maximum position, disconnect the output switch, and the Cummins diesel generator set with a clutch should disconnect the clutch. Start the Cummins diesel generator set with no load first, and then start the Cummins diesel generator set after it runs smoothly. After the Cummins diesel generator set starts to run, you should always pay attention to whether there is mechanical noise, abnormal vibration, etc. After confirming that the situation is normal, adjust the Cummins diesel generator set to the rated speed and the voltage to the rated value, and then close the output switch to supply power to the outside. The load should be gradually increased, striving for a three-phase balance.

The parallel operation of Cummins diesel generator sets must meet the conditions of the same frequency, the same voltage, the same phase, and the same phase sequence. Cummins diesel generator sets that are going to be operated in parallel must all have entered normal and stable operation. Adjust the speed of the Cummins diesel generator set, and close at the synchronization instant. Cummins diesel generator sets running in parallel should adjust the load reasonably, and evenly distribute the active and reactive power of each Cummins diesel generator set. The active power is adjusted through the throttle of the Cummins diesel generator set, and the reactive power is adjusted through excitation. The Cummins diesel generator set in operation should pay close attention to the sound of the engine and observe whether the indications of various instruments are within the normal range. Check whether the Cummins diesel genset is operating normally and whether the temperature rise of the Cummins diesel generator set is too high, and make a record of the operation.
