Causes and solutions of excessive coolant temperature of diesel generator set

As a power generation equipment, diesel generator sets are widely used in our lives. However, excessive coolant temperature will cause harm to the generator set, causing damage to parts at the least and causing the entire generator set to fail to operate normally at the worst. There are many small parts in the diesel generator that deserve our attention in our daily use. Among them, the coolant of the generator is a very important part of the generator. The coolant of the generator plays a role in cooling, anti-corrosion and anti-freezing, which can effectively extend the life of the generator. Common causes of excessive coolant temperature include insufficient coolant, heat sink blockage, etc. The following are the factors that cause excessive coolant temperature and solutions.

Problem 1: Insufficient coolant

Solution: Add coolant

Problem 2: Radiator fins are blocked

Solution: Find and solve the Problem of the blockage and clean the radiator

Problem 3: Poor radiator ventilation

Solution: Increase the effective ventilation area according to installation requirements to ensure smooth ventilation

Problem 4: Abnormal operation of cooling fan

Solution: Check the tension of fan belt and replace the belt if necessary

Problem 5: Fan damage

Solution: Repair or replace

Problem 6: Water pump damage

Solution: Repair or replace

Problem 7: Thermostat failure

Solution Method: Replace

Problem 8: Fuel injection pump failure

Solution: Ask authorized personnel to repair or replace

Problem 9: Incorrect fuel supply timing

Solution: Check the fuel injection pump data and ask authorized personnel to repair and adjust

Problem 10: The ambient (intake) temperature is too high

Solution: Keep the machine room ventilated Problemably to reduce the machine room temperature

Problem 11: The unit is seriously overloaded

Solution: Control the load, and the static unit is overloaded for a long time

Problem 12: Coolant alarm switch (sensor) or instrument failure

Solution: Check the control panel, instrument, body sensor, repair or replace, and troubleshoot
