High Water Temperature in Excavator Engine， Which Part Should Be Responsible for This

Excavator engine is a sophisticated and complex apparatus, can be divided into two major structures and five systems, two major institutions refer to the crank linkage structure, gas distribution structure, five systems refer to the ignition system, fuel supply system, cooling system, lubrication system and starting system. When the excavator engine water temperature remains high, which excavator engine parts should be responsible for this? This article will provide you with a detailed introduction.

Excavator engine water temperature is a more complex fault, the factors affecting more, in the troubleshooting problems need to be carefully analyzed, excavator engine water temperature failure mode has a few of the following several, the following don't explain it.

1. False high water temperature.

False high water temperature refers to the water temperature indicated on the water temperature gauge is high to the red line or even more than the red line, but with the hand touch mold water tank, feel not very hot. This failure should be checked the following parts:

(1) whether the water temperature sensor plug failure, such as water temperature sensor plug damage failure, replace the water temperature sensor plug.

(2) Whether the water temperature meter is faulty, such as water temperature meter damage failure, replace the water temperature meter.

(3) Whether the wiring connecting the water temperature sensing plug and the water temperature gauge is broken, shorted, soldered, or has a defective lap. According to the check out the problem corresponding processing.

2. Real high water temperature

Engine water temperature is high, touch the water tank feels hot, this is a relatively common failure, generally caused by the following reasons.

(1) cooling water tank blockage: this is the excavator engine high temperature is the most common reason, excavator long-term outdoor operations, dust, willow and other debris can easily be clogged radiator, resulting in poor heat dissipation. If the radiator is too dirty, you can use compressed air to blow away the dirt. However, please do not use compressed air or use high-pressure water gun to clean the radiator, easy to damage the radiator scales and other radiator damage.

(2) The water pump does not work or work poorly: in the equipment off state, check whether there is water leakage around the pump, check whether the pump shaft is shaking, slack. If the above state exists, please replace the water pump. When the water pump is not working well, the engine antifreeze circulates at a small speed, and the engine heat cannot be exchanged through the water tank in time, resulting in high temperature.

(3) Poor thermostat operation: the engine thermostat can be adjusted according to the antifreeze temperature of the antifreeze cycle and small cycle, thermostat failure may not be able to convert the antifreeze to large cycle, resulting in high water temperature. Infrared thermometer can be used to measure the temperature of the water tank inlet pipe and outlet pipe, if the temperature difference between the two is large, indicating that the thermostat is damaged, please replace the thermostat.

(4) air duct abnormal circulation: air duct is a problem that many of our users tend to ignore, the engine fan will be cold air from the water tank inhalation, blowing to the engine, and then by the engine above the air outlets, take away part of the engine heat, when the hood is not sealed, the hot air is prone to stay in the engine compartment to form a vortex, which affects the engine heat dissipation and thus generate high temperatures.

When the excavator engine parts are damaged, they need to be replaced in time.
