Method for preventing burning of diesel generator set

Diesel generators have a very important role in our lives, so do you know what methods can prevent diesel generator sets from burning out? Let me introduce them in detail below:

The first is to keep the diesel generator set clean. If dust, water and other debris enter the generator, it will form a short-circuit medium, which may damage the insulation of the conductor, cause shorts between turns, increase the current, increase the temperature, and burn the diesel generator set. Therefore, dust, water and other debris should be prevented from entering the diesel generator set, and the exterior of the diesel generator set should be regularly cleaned, so that the dust and other impurities in the diesel generator set's heat dissipation ribs are not allowed to ensure the heat dissipation of the diesel generator set. In good condition.

Watch and listen carefully. When you smell an odor, stop the machine immediately. Observe the vibration, noise and odor of the diesel generator set. During the operation of diesel generator sets, especially high-power diesel generator sets, check whether the anchor bolts, end covers and bearing glands of diesel generator sets are loose and whether the grounding device is reliable. If it is found that the vibration of the diesel generator set is exacerbated, the noise is increased, and an odor is generated, it must be stopped as soon as possible to find out the cause of the failure.

Keep the working current of the diesel generator set small. Diesel generator sets may be overloaded due to excessive load, low voltage, or mechanical blocking caused by driving. Therefore, during the operation of the diesel generator set, it is necessary to check whether the transmission device is flexible and reliable, whether the concentricity of the coupling is standard, and whether the flexibility of the gear transmission is flexible. If stagnation is found, stop it immediately and put it into operation after removing the fault.

Control equipment of diesel generator sets shall be regularly inspected and maintained to ensure their normal operation. The technical condition of the diesel generator set control equipment plays a decisive role in the normal start of the diesel generator set. Therefore, the control equipment of the diesel generator set should be located in a dry, ventilated and operating place, and regularly removed. Frequently check whether the contactor contacts, coil cores, wiring screws, etc. are reliable, and whether mechanical parts are flexibly moved to maintain their good technical condition, thereby ensuring the smooth operation of the diesel generator set without burning.

Check whether the operating temperature and temperature rise of the diesel generator set are too high. Check the diesel generator set bearings frequently for overheating or lack of oil. If the temperature rise near the bearing is too high, immediately shut down the generator for inspection. There is no crack, scratch or loss on the rolling element and raceway surface of the bearing, the bearing clearance is too large, and the inner ring does not rotate with the shaft. If this occurs, the bearing must be replaced.

It must be checked whether the three-phase current of the diesel generator set is balanced. For three-phase asynchronous diesel generator sets, the difference between the average value of any three-phase current and the other two-phase currents should not exceed 10% to ensure the safe operation of the diesel generator set. If the failure of the diesel generator set is exceeded, the cause should be found out before running.
