Why The WaterTemperature Of The 150kw Shangchai Generator Is Too High

Mar. 08, 2022

Generally speaking, the outlet water temperature of the 150kw Shangchai diesel generator set is preferably around 80°, and the maximum temperature cannot exceed 95°. If the outlet water temperature is too high or too low, it will cause damage to the generator. So do you know why the water temperature of the 150kw Shangchai generator is too high?

 

Reasons and solutions for the high outlet water temperature of 150kw Shangchai diesel generator set:

 

1. There is air in the water pipe: after the 150kw Shangchai diesel generator set is started, the water outlet pipe does not produce water or the water volume is very small, and the water temperature continues to rise.

 

Solution: Loosen the thermometer connector on the drain pipe, deflate until the water is clear, and fasten the connector of the water line.

 

2. The amount of circulating water is insufficient, the load is too large, the outlet water temperature is too high, and the oil temperature rises.

 

(1) The speed of the fresh water pump or fan cannot be reached.

Solution: Adjust the tension of the triangle tape to the specified value.

 

(2) The impeller of the fresh water pump is damaged.

Solution: replace the fresh water pump impeller.

 

(3) The interference gap between the impeller of the fresh water pump (referring to the wheel disc with moving blades) and the casing.

Workaround: Adjust the gap to the specified value.

 

(4) In the open cycle, the water level of the water source is too low, and the fresh water pump cannot absorb the water coming and going.

Solution: Increase the water level of the water source.

 

(5) In the closed cycle, eliminate the lack of water in the radiator.

Solution: increase cooling water.

 

(6) The water pipe is blocked.

Solution: Clean the pipes and remove the scale in the cooling passages.

3. In the closed cycle, the surface area of the radiator is too large, which affects the heat dissipation.

Solution: Remove dirt and clean surfaces.

 

4. Thermostat failure.

Solution: Repair or replace the thermostat.

 

5. Cracks appear in the shoulder blade of the cylinder liner. At this time, the cooling water in the radiator has bubbles that need to be eliminated: replace the cylinder liner
