For this kind of problem, it is usually especially common in summer, but in some cases, in winter, some cases, there are also cases. However, do not ignore this kind of problem. If this kind of problem occurs, then the excavator is out of order. Well, this kind of problem, how Do You Fix It? First of all, let's first analyze the causes of excavator failure 1. When the excavator idles, the engine water temperature meter shows too high, the Electronic Fan high-speed block works too long, and the engine noise increases, the fault is obvious when the temperature is too high to turn on the air conditioner. Excavator maintenance: check the condenser and water tank between the dust is too much, with high-pressure gas thorough cleaning, to ensure that the water tank and condenser have good heat dissipation performance. Usually pay attention to wipe the condenser and water tank between the dust. 2, in the air conditioning temperature is too high, idle speed fluctuations too large, rapid acceleration inability, the engine has abnormal sound. Excavator maintenance, check the temperature difference between the upper and lower pipes of the water tank, if the temperature difference is too large, you need to check the opening of the thermostat and whether the pump speed loss of the fault. The temperature difference between the top and bottom pipes of the tank must not be too great. 3. When the hot car stops running for more than 10 minutes, it is not easy to start the car; when the hot car is running, it will sometimes automatically stop running. Solution: Hot car, check the antifreeze storage tank on the top of the backwater pipe backwater, if backwater is not smooth or blocked will cause high water temperature. Warm Reminder: Do not blindly remove parts and replace parts in excavator maintenance. 4. The cooling temperature of air-conditioning is very cool when the car is cold, The cooling effect is not obvious when the car is hot, and there is a big resonance buzz in the air-conditioning system. Due to the irregular addition and replacement of antifreeze in excavator maintenance, the engine channel and water tank will be blocked ahead of time and the water temperature will be high. Antifreeze is replaced every two years. Original parts must be used when replacing and adding antifreeze. 5, idling hot car, air conditioning compressor clutch suction off frequently, or even off, resulting in hot car air conditioning is not refrigeration. Excavator maintenance air conditioning system in the high pressure side too high; air conditioning refrigerant or air conditioning refrigeration lubricating oil injection too much; internal self-regulating air conditioning compressor self-regulating function failure, resulting in high pressure; there is also air conditioning condenser blockage, the above faults will increase the engine load, consumption of cooling system cooling performance, guidance water temperature too high failure occurs. Warm Reminder: Air Conditioning refrigerant filling too little or too much, will reduce the cooling effect. Above excavator failure, will cause the water temperature is too high, so, in peacetime encounter this situation, you can find professional excavator maintenance technicians check.
