More and more excavator master focus on maintenance of this piece of excavator, Anhui excavator because the operation process of the excavator will inevitably encounter problems or failure, as a mechanic if you do not have to diagnose their own excavators, then can only say that you are not entirely an excavator technician.

Furthermore, because the world is mostly used in excavator second-hand excavator, so when the overload operation, is broken.

The following is about how the excavator maintenance expert to remove the engine temperature is too high:

One, "see"

The engine temperature is too high or the temperature indicator lights keep shining, want to stop check, Guizhou excavator to see if the water tank cooling water is normal, the tank, the water pipe and the joints have no leakage phenomenon. If the abnormal appearance of the examination are not found, you can make up for 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. This failure, maintenance should be carried out, do not let down.

Two, "red"

If the dirt adhering to the radiator, in the course of time, will affect the cooling effect, caused by excessive temperature. Can first use the compressed air to blow the radiator grille, and then the water pipe flushing.

In general, the temperature is too high to solve the excavator engine has four main steps "at the second and the three party, Si Chong," as long as a good grasp of these four steps, you can be a reasonable solution to the problem of high temperature engine!

Three, "touch"

When the engine temperature is too high, you can use the hand to touch the temperature of the water pipe and the water pipe to determine the fault location. If the temperature difference between the two pipes is very large, it can be judged as a thermostat does not work. In the purchase of less than the temporary, can be removed from the thermostat emergency, to be replaced immediately after a replacement.

Four "

If there is air in the cooling system, it will form the air resistance, so that the cooling water circulation, resulting in engine temperature is too high. Guizhou excavator 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 pipe temperature will be significantly different). After troubleshooting, should be added to the cooling water.
