Methods to Prevent Emergency Generator Set Burnout

Today Starlight Power introduces how to prevent emergency diesel generator set from burning out. Hope it is helpful for everybody.

1.Keep diesel generator set clean.

In the operation of diesel generator set, if dust, water stains and other debris enter into the diesel generator set, it will form short-circuit medium, which can damage the insulation layer of conductor and form turn to turn short circuit. With the increase of current and temperature, the diesel generator set will be burned. Therefore, we should prevent dust, water stains and other debris from entering into diesel generator set. At the same time, we should also often clean the exterior of diesel generator set. Do not let dust and other sundries exist in the cooling rib of diesel generator set, so as to ensure the heat dissipation of diesel generator set.

2.Frequent inspection, listen carefully, when smell something, immediately shut down.

Check the diesel generator set for vibration, noise and abnormal smell. In the operation of diesel generator set, especially high-power diesel generator set, it is necessary to check whether the anchor bolt, end cover and bearing cover of diesel generator set are loose, and whether the grounding device is reliable. If it is found that the vibration of the diesel generator set increases, the noise increases and the odor appears, it is necessary to stop the diesel generator set as soon as possible, find out the causes and eliminate the shortcomings.

3.The working current of diesel generator set can not over high.

The overload operation of diesel generator set will be caused by excessive load, too low voltage or mechanical blockage caused by action. Therefore, in the operation of diesel generator set, attention should be paid to check whether the operation of transmission device is flexible and reliable; whether the concentricity of coupling can be standardized; the flexibility of gear transmission, etc. if there is any jamming phenomenon, it is necessary to stop the machine and eliminate the defects before operation.

4.Timely check and repair the control equipment of diesel generator set to ensure its normal operation.

The technical condition of control equipment of diesel generator set plays a decisive role in the normal starting of diesel generator set. Therefore, the control equipment of diesel generator set should be set in the direction of monotonous, ventilation and easy operation, and be punctual to remove dust. Often check whether the contactor contact, coil iron core, wiring screws, etc. are reliable, whether the mechanical parts can move flexibly, so that they can adhere to the excellent technical conditions, and then ensure the smooth operation of the diesel generator set without being burned.

5.Often check whether the temperature and temperature rise of diesel generator set are too high.

It is necessary to check whether the bearing of diesel generator set can overheat and lack of oil. If the temperature rise near the bearing is too high, it should be stopped immediately for inspection. Whether there are cracks, scratches or defects on the surface of the rolling body and raceway of the bearing, whether the bearing can shake too much in the open space, whether the inner ring changes on the shaft, etc. It is necessary to renew the bearing.

6.Often check whether the three-phase current of diesel generator set can be balanced.

For three-phase asynchronous diesel generator set, the difference between any one phase current of three-phase current and the average value of other two-phase current is not allowed to exceed 10%, so as to ensure the safe operation of diesel generator set. If it is exceeded, it is indicated that the diesel generator set has defects, which should be checked and removed before operation.
