How to prevent MTU diesel generator from burning down

1. Regularly check and maintain the control equipment of diesel generator set to ensure its normal operation

The technical condition of diesel generator set control equipment plays a decisive role in the normal start of diesel generator set. Therefore, the control equipment of diesel generator set should be located in a dry, ventilated and easy to operate position, and regular dust removal. Often check whether the contactor contact, coil core, wiring screws, etc., is reliable, mechanical parts are flexible, so as to maintain a good technical state, so as to ensure that the diesel generator set work smoothly without being burned.

2. Often check whether the three-phase current of diesel generator sets is balanced

Three phase diesel generator set, its three phase current any phase current and other two phase current average difference is not allowed to exceed 10%, so as to ensure the safe operation of diesel generator set. If it is over, it indicates that the diesel generator set is faulty. It should be operated after finding out the reason and eliminating the fault.

3. Always check whether the temperature and temperature rise of diesel generator set are too high in operation

It is necessary to often check whether the bearings of diesel generator sets are overheating and lack of oil. If the temperature rise near the bearings is too high, it should be stopped immediately for inspection. Whether there is crack, scratch or damage on the surface of the rolling body and raceway of the bearing, whether the bearing clearance is too shaky, whether the inner ring rotates on the shaft, etc. When the above phenomenon occurs, the bearing must be updated.

4. Whether the use environment of diesel generator set is clean

Diesel generator set in operation, if there are dust, water stains and other debris into its interior, will form a short circuit medium, can damage the wire insulation layer, cause inter-turn short circuit, current increases, temperature rises and burn diesel generator set. Dust, water stains and other sundries should be prevented from entering the diesel generator set. At the same time, the exterior of the diesel generator set should be cleaned regularly. Do not let the heat dissipation bar of the diesel generator set contain dust and other sundries to ensure that the heat dissipation of the diesel generator set is good.

5. In the process of using diesel generator set to do "frequent observation", "listen carefully", smell odor immediately stop.

The analysis should observe whether the diesel generator set has vibration, noise and abnormal odor. Diesel generator set in operation, especially high-power diesel generator set should often check whether the anchor bolt, diesel generator set end cover, bearing gland is loose, grounding device is reliable, etc. If it is found that the diesel generator set vibration intensifies, noise increases and peculiar smell occurs, it must be shut down as soon as possible to find out the cause and eliminate the fault.

6. Keep the diesel generator set from overload

Diesel generator set due to excessive load, low voltage or driven mechanical stagnation will cause diesel generator set overload operation. Therefore, in the operation of diesel generator sets, we should pay attention to check whether the transmission device is flexible and reliable; Whether the concentricity of the coupling is standard; Gear transmission flexibility, if found stuck phenomenon, should immediately stop troubleshooting before running.
