The core solution to the malfunction of a
diesel generator sets thermostat is to inspect and replace the faulty thermostat. If the thermostat fails, it will cause the diesel generator to be unable to adjust the water temperature properly, thereby affecting the performance and lifespan of the engine.
Firstly, common manifestations of thermostat malfunctions include high cooling water temperature inside the diesel engine, but low water temperature in the radiator tank. In addition, a malfunction of the thermostat may also cause the diesel engine to overheat, resulting in a chaotic metallic knocking sound during acceleration, which can easily cause parts to get stuck or break.
Next, the specific processing method is as follows:
Check the thermostat: The thermostat can be removed and the diesel engine can be started. If the water temperature is normal at this time, it can be concluded that the thermostat has failed and should be repaired or replaced.
Check the cooling system: Ensure that the coolant is used correctly and the remaining amount is sufficient, check whether the water tank, water pump, and cooling water pipeline are unobstructed, and remove scale and impurities.
Check the fan: Ensure that the fan is running properly, the belt is moderately tight, and replace damaged components if necessary.
Check sensors and control systems: Use external detection equipment to measure water temperature and ensure that the displayed temperature is consistent with the actual temperature. If the sensor or control system malfunctions, the relevant components should be replaced or repaired.
Finally, preventive measures include regular maintenance of the cooling system and thermostat, avoiding long-term overload operation, keeping the cooling system clean and unobstructed, and timely replacement of aging and worn components.
