You said that turning the water over could cause it to heat up and overflow. The main reason is that the water temperature is too high.
Normal cooling water temperature should be between 70 and 80 degrees. If the temperature exceeds 100 degrees, it will be abnormal. Possible reasons:
1. The cooling fan is inefficient and cannot remove heat from the water.
2. The thermostatic valve in the cooling water tank has failed. There was only a little circulation but no major circulation, which caused the temperature to rise.
The main reasons that cause the diesel generator set temperature to be too high are:
1. The diesel engine uses hard water for a long time and a large amount of scale is formed. into the water tank and waterways, resulting in poor heat dissipation.
2. There are too many impurities deposited in the water channels between the body and the cylinder head, which blocks the circulation of water and leads to poor heat dissipation.
3. Seriously burns engine oil, causing excessive carbon deposits and poor heat dissipation.
4. Improper operation and use. When starting the diesel engine, you must first use a small or medium throttle to preheat for a while. Do not suddenly increase the throttle or suddenly increase the load, otherwise the diesel engine will run abruptly and the temperature will rise sharply. Or, long-term overload operation of the diesel engine will also cause the diesel engine to become too hot.
5. Delaying fuel delivery too late will cause the diesel engine to overheat.
6. Put it into operation at full load immediately after repair, causing overheatinge or blocking of moving parts due to too little mounting clearance.
7. Insufficient cooling water causes the diesel engine to overheat.
If the temperature of the diesel engine of the diesel generator set is too high, it will cause reduced matching clearance, resistance and poor lubrication of moving parts in severe cases. cause cylinder pulling and shaft holding accidents. Therefore, when the temperature of the diesel generator set is too high, it should be repaired in time.
