Today we will briefly introduce to you how to effectively prevent the breakdown of diesel generator sets.
Keep the diesel generator set clean: During the operation of the diesel generator set, if dust, water stains and other sundries enter into it, a short-circuit medium will be formed, which can damage the insulation layer of the wire, cause a short circuit between turns, increase the current, and increase the temperature. High and burn out the diesel generator set. Therefore, dust, water stains and other debris should be prevented from entering the interior of the diesel generator set. At the same time, the exterior of the diesel generator set should be cleaned frequently. Do not let dust and other debris in the heat dissipation ribs of the diesel generator set to ensure diesel power generation. The cooling of the unit is in good condition.
Observe and listen carefully, stop immediately if you smell peculiar smell: observe whether the diesel generator set has vibration, noise and abnormal smell. During the operation of diesel generator sets, especially high-power diesel generator sets, it is necessary to frequently check whether the anchor bolts, diesel generator set end covers, bearing glands, etc. are loose, and whether the grounding device is reliable. If it is found that the vibration of the diesel generator set is intensified, the noise increases and there is an odor, it must be stopped as soon as possible to find out the cause and eliminate the fault.
Keep the working load of the diesel generator set not too large: the diesel generator set will be overloaded due to excessive load, low voltage or driven mechanical stagnation. Therefore, during the operation of the diesel generator set, it is necessary to always check whether the transmission is flexible and reliable; whether the concentricity of the coupling is standard; the flexibility of the gear transmission, etc. If it is found that there is a stuck phenomenon, it should be stopped immediately to remove the fault and then run.
Regularly check and maintain the control equipment of the diesel generator set to ensure its normal operation: the technical condition of the control equipment of the diesel generator set 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 easy-to-operate location, and dust should be removed regularly. Always check whether the contactor contacts, coil cores, and various wiring screws are reliable, and whether the mechanical parts are flexible, so that they can maintain a good technical state, so as to ensure the smooth operation of the diesel generator set without being burned.
Frequently check whether the temperature and temperature rise of the diesel generator set during operation are too high: Always check whether the bearing of the diesel generator set is overheated and lack of oil. If the temperature rise near the bearing is found to be too high, it should be stopped immediately for inspection. Whether the rolling elements and raceway surfaces of the bearing are cracked, scratched or damaged, whether the bearing clearance is too large and shaken, whether the inner ring rotates on the shaft, etc. When the above phenomenon occurs, the bearing must be updated.
Always check whether the three-phase current of the diesel generator set is balanced: the three-phase asynchronous diesel generator set, the difference between any one-phase current of the three-phase current and the average value of the other two-phase currents is not allowed to exceed 10%, so as to ensure the safe operation of the diesel generator set. If it exceeds, it indicates that the diesel generator set is faulty, and the reason should be found out and the fault is removed before running.
