How to troubleshoot the Lingong excavators

Engineering machinery home today Xiaobian to share with you everyday how to troubleshoot the Lingong excavators.

Excavator maintenance, the most common, high water temperature, then how to exclude it? Here are 4 aspects:

First, "see": found that the engine temperature is too high, or the temperature indicator constantly flashing, to stop inspection, see the water tank cooling water is normal, the water tank, water pipes and joints at any leakage. How water is not enough, in time to add water to burn the machine, if not checked by the appearance of anomalies, you can make up the required cooling water, and then continue to work. If after a period of time, is that temperature is too high, stop checking found that cooling water decrease very much, this is mostly because of the water jacket gas cylinder has hole or perforation and loss. After finding this fault, it should be repaired and never be taken lightly.

Two, "touch": when the engine temperature is too high, you can use hand to touch the water pipe and the temperature of the underwater pipe to determine the fault. If the temperature difference between the two pipes is very large, they can be judged as thermostat and do not work. New thermostat needs to be replaced, and parts can not be purchased at the moment. Emergency thermostat can be removed and replaced immediately after fitting.

Three, "put": if there is air in the cooling system, will form gas resistance, make the cooling water cycle bad, cause the engine temperature is too high. May adopt the following approach: let the gas engine running in high speed, the tank cover to just gently unscrew the gas is released, at this time there will be a part of the cooling water flow together with the gas, so repeatedly, until you feel the gas discharge end (at the same time, touch the upper and lower water temperature will be significantly different). After the troubleshooting, the cooling water should be added in time.

Four, "Chong": if dirt adhered to the radiator, over time, will affect the heat dissipation effect, causing the water temperature is too high. You can use the compressed air to blow the radiator grille and flush with the pipe.

"Look, three, four, the second mock exam red" is the investigation summary of the 8 character principle of excavator.
