Excavators will have certain problems during use in winter, so how should we deal with these high-temperature faults? What is the cause analysis of the fault phenomenon?
Reasons for high oil temperature of excavator:
1. Problems of excavator hydraulic pump
2. Does the hydraulic pressure used deteriorate? Haven't changed in a long time?
3. Internal leakage of excavator hydraulic system
4. And the computer board
5. Excavator one-way valve failure
The cooler outside the filter is blocked
Reasons for high water temperature of excavator:
1. Tightness of control belt of excavator fan
2. Cleanliness of water tank
3. The radiator of the excavator is blocked, causing the high temperature fault of Carter 320d excavator
4. Is the radiator dirty
5. Excavator thermostat
Use antifreeze or tap water. If the water is too long, scale will be generated
7. There is a relationship between excavator, water tank cover, etc
Common treatment methods for excavator high temperature:
When the water temperature is high, the excavator owner can first check whether the water tank is dirty? Radiator is unusual work? These filters are not blocked? Is the fan belt loose? It is suggested that if the thermostat needs to be disconnected, and if the above method cannot eliminate the failure of high temperature treatment, the engine needs to be overhauled. How many hours have not changed? In addition to hydraulic oil, check radiator excavator, filter, check valve, etc.
