Why The Water Temperature Of 150kw Shangchai Generator Is Too High

Nov. 12, 2021

Generally speaking, the outlet water temperature of the 150kw Shangchai diesel generator set is around 80°, and the maximum should not 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 150kw Shangchai generator is too high?


Reasons and solutions for the high temperature of the outlet water 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 flow out 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 tighten the connector of the water pipe.


2. The 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 fresh water pump impeller is damaged.


Solution: Replace the fresh water pump impeller.


(3) The interference clearance between the fresh water pump impeller (referring to the disk with moving blades) and the shell.


Solution: 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) Eliminate the lack of water in the radiator in a closed cycle.


Solution: increase cooling water.


(6) The water pipe is blocked.


Solution: Clean the pipes and remove the scales in the cooling channels.


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


Solution: Remove dirt and clean the surface.


4. The thermostat malfunctions.


Solution: repair or replace the thermostat.


5. There is a crack in the shoulder blade of the cylinder liner. At this time, the cooling water in the radiator has bubbles and needs to be eliminated: replace the cylinder liner.
