How to Prevent Diesel Genset from Burning Out at High Temperature in Summer

The diesel generator set itself is a sharp tool for generating heat. In hot summer, heat dissipation must be considered when using the diesel generator set. How to prevent excessive engine temperature when using a generator set is easily overlooked. So how should we prevent the diesel generator set from burning out at high temperature in summer?

How to effectively prevent diesel generator set from burning out？

1. Make the diesel generator set clean. During the operation of the 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, increased current, and temperature rise, which will burn the diesel generator set. Therefore, it is necessary to prevent dust, water stains and other sundries from entering the diesel generator set. At the same time, it is necessary to regularly clean the outside of the diesel generator set. Do not allow dust and other sundries in the heat dissipation rib of the diesel generator set, so as to ensure that the heat dissipation of the diesel generator set is good.

2. Observe and listen carefully, and stop the machine immediately when you smell a strange smell. Observe the generator set for vibration, noise, and abnormal odors. During the operation of the generator set, especially the high-power diesel generator set, it is necessary to frequently check whether the anchor bolts, 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.

3. Keep the working current of the generator set at a minimum. The overload operation of a generator set can be caused by 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.

4. Regularly inspect and repair the control equipment of the generator set to ensure its normal operation. The technical condition of the control equipment of the generator set 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 and ensure the smooth operation of the generator set without being burned.

What is the reason for the high temperature in diesel power generation?

1. Long term overload operation. Prolonged overload operation of diesel engines can increase their fuel consumption, resulting in excessive water temperature. So it is necessary to avoid prolonged overload operations.

2. Insufficient coolant. If there is a lack of coolant in the diesel engine cooling system, it will affect the heat dissipation effect of the diesel engine and cause high temperatures. Check the coolant stock in the radiator and expansion tank frequently, and replenish in time when the liquid level is low.

3. Poor circulation of coolant. Insufficient opening of the thermostat will reduce the heat dissipation capacity of the diesel engine cooling system systemic circulation. If the diesel engine is hot, the thermostat can be placed in water for heating inspection.

4. There are debris attached to the surface of the radiator. The attachment of debris on the surface of the radiator will reduce the heat dissipation area of the radiator, and the windward area of the radiator will decrease, leading to a decrease in the heat dissipation capacity of the radiator and causing high temperatures in the diesel engine.
