During the operation of Cummins diesel generator set, if dust, water stains and other sundries enter its interior, a short circuit medium will be formed, which can damage the insulation layer of the conductor, resulting in inter turn short circuit, current increase, temperature rise and burning of Cummins diesel generator set.
Therefore, it is necessary to prevent dust, water stains and other sundries from entering into the Cummins diesel generator set. At the same time, it is necessary to regularly clean the outside of the Cummins diesel generator set. Do not allow dust and other sundries in the heat dissipation ribs of the diesel generator set to ensure that the heat dissipation of the diesel generator set is in good condition.
Observe whether Cummins diesel generator set has vibration, noise and abnormal smell. During the operation of the diesel generator set, especially the high-power diesel generator set, it is necessary to frequently check whether the anchor bolts, diesel generator set end caps, bearing glands, etc. are loose, and whether the grounding device is reliable. If the diesel generator set is found to have increased vibration, noise and odor, it must be shut down as soon as possible to find out the cause and eliminate the fault.
Cummins generator sets can overload due to excessive load, low voltage, or mechanical jamming caused by the drive. Therefore, during the operation of the generator set, it is necessary to regularly check whether the transmission device operates flexibly and reliably; Is the concentricity of the coupling standard; Flexibility of gear transmission, etc. If any jamming is found, the machine should be immediately shut down to troubleshoot before running.
The technical condition of Cummins generating set control equipment plays a decisive role in the normal start-up of the generator set. Therefore, the control equipment of the generator set should be located in a dry, ventilated, and easy to operate position, and regularly remove dust. Regularly check the reliability of contactor contacts, coil cores, and various wiring screws, as well as the flexibility of mechanical parts to maintain good technical condition, in order to ensure the normal operation of the generator set without being burned.
It can be seen that starting from the details is the key to preventing the burning failure of the generator set. At the same time, we also need to pay close attention to the symptoms of the burning failure, correspond the burning failure of the generator set to its cause one by one, and improve the standardization of the use and maintenance of the generator set. Only in this way can we minimize the occurrence of the burning failure of the generator set.
