Kobelco Excavator Repair
Kobe Steel Excavator Abnormal Water Temperature
The abnormal water temperature of the Kobelco excavator during the work is a problem that many users have encountered. How do you determine what is wrong with the excavator when this kind of problem occurs? Everyone picks firewood and the flame is high, look at the owners How to repair the abnormal water temperature of the excavator? How can the maintenance master answer this question?
Problem model: My Kobelco SK was purchased on April 27th. The current working time is more than 9,000 hours, engaged in earthmoving work. It was maintained by the agent 2500 hours ago, and the original assembly (assemble) I purchased after 2500 hours. In August, the working time of the excavate machine was about 8,400 hours, and water leakage occurred in the engine water pipe. Since there was no after-sales service in the road construction in Jiangxi at the time, this situation was not dealt with in time, but two bottles of pure water were added daily. Water (ordinary vial of pure water). This situation lasted for more than a month. After the road repair was completed, the excavator was repaired. There was no water seepage, but in winter, the excavator was replaced. Antifreeze coolant (not Kobelco's pure antifreeze) will have a high water temperature, so let go of the antifreeze and replace it with pure water, and the water temperature will drop back to normal. What is the reason for this problem?
Answer: Hello, Mr. Wanzhou Li Wandong, the problem you mentioned should be that there is a problem with the antifreeze coolant you selected. It is recommended that you use Kobelco's pure antifreeze coolant.

Answer from the maintenance master: According to the customer description, the effect of the non-Kobelco pure antifreeze coolant used by the customer is not as good as pure water. In this case, it indicates that the quality of this antifreeze product is extremely low. It is recommended not to use it. The corrosion of the engine's waterway (interpretation: refers to decay, disappearance, erosion, etc.) is much stronger than the pure antifreeze, and it is recommended to use it as little as possible. The high temperature of this antifreeze is due to the specific heat of this liquid Lower, in other words, the ability to absorb heat generated by the engine at a unit temperature is weak.

Problem model: My Kobelco SK60C was purchased on April 23, and currently works for about 400 hours. It is engaged in earthmoving work in the suburbs and is regularly maintained by agents. The excavate machine does not lift its boom in 100 hours. The bucket did not move around 200 hours. The after-sales staff was contacted. The problem has not been resolved so far. At 300 hours, it is impossible to work at noon. As soon as noon, the temperature is high and cannot work, which has affected the excavation. Machine is working normally, what is the reason?
Answer: Personal opinion, I think the symptoms at 100 hours and 200 hours should be the issue of the solenoid valve (magnet valve) or the problem of the computer board. Do an electromechanical adjustment. The temperature is high, it should be the water tank (components: high water tank, storage tank, low water tank). The heat dissipation effect is not good. Check the tension of the fan belt, check whether there is dirt inside and outside the water tank, and thermostat. And whether the circulation pump is in good condition.
