Because most of the excavators are second-hand long arm excavators, the waist will inevitably break when the long arm excavators are overloaded. The following is about how the maintenance technology of the long arm excavator can eliminate the high temperature fault of the engine of the long arm excavator.
If it is found that the engine temperature is too high or the temperature indicator flashes continuously, it is necessary to stop checking to see whether the water tank is normal and whether there is water leakage in the water tank, water pipe and joint. If no abnormality is found by external inspection, the cooling water can be supplemented according to the regulations, and then continue to work. If the temperature is still too high after working for a period of time, cooling water is found to be much reduced during shutdown inspection, which is mainly due to the loss of sand holes or perforations on the cylinder block water jacket. When this fault is found, it should be repaired, and must not be taken lightly.
When the engine temperature is too high, the fault can be judged by touching the temperature of the water pipe and the underwater pipe. If the temperature difference between the two pipes is large, it can be judged that the thermostat does not work. When temporarily purchasing fittings, the thermostat can be disassembled urgently, and the fittings can be replaced immediately.
If there is air in the cooling system, it will form air resistance, make the cooling water circulate badly, and cause the engine temperature to be too high. The following methods can be used to release air: let the engine run at high speed, gently unscrew the water tank cover until some gas is released, then some cooling water will flow with the gas, many times, until you feel the gas (at this point, the temperature of contacting the upper and lower pipes will be significantly different). After troubleshooting, the cooling water should be replenished in time.
If the dirt is attached to the radiator when the long arm excavator is leased, over time, it will affect the heat dissipation effect and cause the water temperature to be too high. The radiator grille can be blown with compressed air before being flushed with water pipes.
To solve the problem of high temperature of long arm excavator engine, there are generally four steps: "one look, two modes, third sides, four impulse". As long as we master these four steps, we can reasonably solve the problem of high engine temperature of long arm excavator.
