Many excavator masters pay attention to the maintenance of excavators, because it is inevitable that they will not encounter problems during the entire operation of excavators, that is to say, failures. Although small excavators are easy to use, they will be actually operated and do not mean maintenance Maintain your own "love machine", so if you know how to excavator, you also need to know a little about excavator repair. Today's web editor will accompany you to analyze the excavator repair method, don't thank you too much.
Here is how the excavator maintenance god clears the excavator engine temperature failure:
one look"
It is found that the temperature of the diesel engine is too high or the temperature indicator light is constantly flashing. Check whether the cooling water in the water storage tank is normal, and whether there is any leakage in the water storage tank, tap water pipes and various connections. If there is no abnormality according to the surface inspection, the cooling water can be added in accordance with the regulations before working again.
If the temperature is still too high after working for a period of time, and the parking inspection finds that the cooling water has dropped too much, this is mostly due to sand holes or broken holes in the water jacket of the cylinder block. After discovering this fault, maintenance should be carried out, and no luck should be allowed.
2. "Chong"
If the dirt sticks to the heat pipe radiator for a long time, it will endanger the actual heat dissipation effect of the heat pipe and cause the temperature to be too high. The heat pipe radiator grid should be blown with air compression first, and then cleaned with a tap water pipe.
To sum up, there are four key processes to deal with the excessive temperature of the excavator engine. "One look, two modes, three directions, four strokes." If you grasp these four processes, you can effectively deal with the excessive temperature of the excavator engine problem!
Three, "touch"
When the temperature of the diesel engine is too high, you can touch the temperature of the water inlet pipe and the water bottom pipe to distinguish the fault. If the temperature difference between the two water pipes is too large, it can be judged that the thermometer is not working. If you can’t buy spare parts temporarily, the detachable thermometer is urgent, and it will be replaced immediately after a spare part.
Four, "release"
If there is gas in the refrigeration system, air resistance will occur, which will make the cooling water circulation system poor and cause the diesel engine to overheat. The following methods can be used to release the air: Let the diesel engine run at high speed, and gently twist the water tank cover until the vapor is released. At this time, a part of the cooling water will be discharged with the vapor. This is repeated several times until you feel that The steam has been exhausted (the temperature of the upper and lower water pipes will be significantly different at this time). After the fault is cleared, the cooling water should be filled immediately.
