The high oil temperature of excavator is very harmful, which has a great impact on the performance and life of the machine. Pay attention to this problem during the operation of the machine, and timely find and handle it. In order to solve the problem of high oil temperature of excavators, we should first determine the cause, find the root cause, and prescribe the right remedy. Today, what is the problem of high oil temperature in digging?
Reasons for high oil temperature during excavator repair:
1. The operating environment temperature of the excavator is too high Sometimes, if the operating environment temperature of the excavator is too high or there is a high temperature heat radiation source near the oil tank, it may cause high temperature. Therefore, it is necessary to avoid heat sources as much as possible when operating under high temperature conditions.
2. The hydraulic oil tank of the excavator has insufficient heat dissipation area, and the heat dissipation is not timely, and the excess heat energy cannot be discharged in time, resulting in high temperature. Therefore, generally, the capacity of the excavator oil tank should be selected according to 2-6 times of the pump flow or the oil temperature cooling device should be added.
3. The hydraulic oil with different viscosity should be selected according to the different operating environment. For example, the oil with higher viscosity should be selected in winter to ensure the normal operation of the excavator.
4. Failure of hydraulic system of excavator, such as abnormal overflow of safety valve, will cause abnormal rise of oil temperature If the excavator engine is overloaded for a long time, or the hydraulic pump is overloaded, the excavator oil temperature will also be high.
5. If the hydraulic oil of the excavator deteriorates, use regular hydraulic oil to clean the oil return circuit.
6. There is a lack of coolant or there is a problem with the excavator cooling system.
7. High water temperature of excavator may also cause high temperature of hydraulic oil of excavator.
The main reason why the high temperature fault of hydraulic oil is difficult is that there are many components that can cause the fault. From the most basic oil quality to the general oil return check valve stuck to the complex cooling system fault, it will be very difficult to repair. At the same time, we also remind you that the temperature in summer is relatively high, so during the normal operation of the machine, we must always pay attention to the machine, and strive to find abnormalities at the first time!
