Las principales razones de la alta temperatura del agua de la excavadora.

The main reasons for the high water temperature of the excavator include the following aspects:

1. Insufficient coolant: The engine will generate a lot of unused heat when working. If the coolant is insufficient, the heat removal effect will be greatly reduced, resulting in an increase in water temperature. ‌

2. Thermostat failure: The thermostat valve gradually opens at 78-88℃ as the temperature of the diesel engine gradually rises, participating in the engine's large cycle refrigeration. Thermostat failure will cause the cooling cycle to be blocked and cause the engine to overheat.

3. Too much or too little engine oil: Too much oil will cause the engine to encounter greater friction when working, while too little oil will affect the lubrication and heat dissipation effect. ‌

4. Fan failure: Fan rupture or fatigue failure will cause the cooling fan to stop or run slowly, affecting heat dissipation.

5. Oil filter problem: Poor quality oil filter is easy to clog, lose its filtering effect, and increase the burden on the engine. 6. Water pump failure: Water pump problems cause poor water flow and affect the circulation of coolant.  ‌

7. Radiator blockage: The radiator surface is covered with dust and sand, blocking the heat dissipation channel, resulting in insufficient heat dissipation capacity. ‌

8. Air conditioning system failure: The high pressure end of the air conditioning system is too high or the refrigerant and lubricating oil are too much, affecting the engine's heat dissipation performance. ‌

9. Improper fan belt tension: Improper fan belt tension will cause insufficient fan speed and ineffective heat dissipation. ‌
