Fault analysis of high water temperature and high oil temperature of excavator
First, high water temperature phenomenon
The thermostat is stuck, not open, then the water can only take small circulation, not through the radiator.
The dirty water inside the tank, is not smooth.
The fan speed is not enough, clutch failure. (or checking the tightness of the belt)
The damaged tape around the radiator, then the eddy current generated by hot air circulation, can not achieve the cooling effect.
The check work.
. for this, we will not be easy to ignore, is a false alarm, sensor, computer is not only the data after all to see the truth.
Two 、 high temperature phenomenon of hydraulic oil
The main reason for the high temperature of hydraulic oil is too fast heating or too slow heat dissipation. The hydraulic pump inlet pipe and hydraulic oil seal, oil filter blockage, hydraulic piping system is not smooth, the internal pump leakage will cause the hydraulic oil to generate a lot of heat, so that the hydraulic oil temperature for heat production and rapid rise too fast. Hydraulic oil cooler internal blockage, radiator external dust is too large, the hydraulic oil hydraulic oil radiator and other causes of the hydraulic oil cooling temperature is too slow and ruptured.
