When the hydraulic oil temperature of the excavator exceeds 70°C during operation, the excavator oil temperature is regarded as high.
1. The key reasons leading to this situation are roughly divided into two points:
1. The working temperature of the excavator is high;
2. The oil temperature of the excavator itself is high;
2. Because external factors are unavoidable, people will analyze it one by one due to the increase in the oil temperature of the excavator itself:
1. The total heat dissipation area of the heat pipe of the hydraulic oil tank of the excavator is not enough, which causes the heat pipe to dissipate heat not immediately, and unnecessary energy cannot be discharged immediately during the operation, resulting in high temperature conditions in the equipment;
2. When the excavator works for a long time, the hydraulic oil pump or valve is abnormal, it will also cause the oil temperature to rise;
3. Water cooling failure or unqualified refrigerant water rate;
4. The remaining oil of the excavator is not enough;
5. The temperature of the excavator is too high, which causes the temperature of the hydraulic oil of the excavator to rise;
6. Different hydraulic oils should be used in different natural environments. For example, hydraulic oils with low viscosity should be selected in high temperature and summer; on the contrary, hydraulic oils with high relative viscosity should be selected in ultra-low temperature winter, and hydraulic oils should be selected for purpose. Oil to ensure normal operation in all natural environments;
7. Finally, if environmental factors cannot be selected, try to prevent operation in a natural environment with high temperature and high radiation.
Regarding the eight elements clearly put forward by Merit Web Editor, do you already understand how to deal with the problem of excessive excavator oil temperature? Perseverance, more observation, more maintenance, more maintenance. Adhering to the "three-to-many" standard can avoid the increase in the temperature of the excavator oil in many ways.
