Thermostat

How does a thermostat work?

1. The function of the excavator thermostat
The excavator thermostat is an important component of the excavator engine, and its function is to ensure the normal operation of the engine. Specifically, the excavator thermostat has the following three main functions:
1. Monitor engine cooling water temperature
The excavator thermostat ensures the stability of the engine temperature by monitoring the temperature of the engine cooling water. When the engine is working, the temperature of the cooling water will change with changes in speed and load. The excavator thermostat will feedback these changes and control it to maintain it within an appropriate working range.
2. Control air supply and exhaust
The excavator thermostat controls the increase and decrease in engine temperature by controlling the air supply and exhaust. When the engine temperature rises, the excavator thermostat will control the cooling method to ensure the stability and safety of the engine.
3. Increase engine life
The excavator thermostat can effectively protect the engine and extend its life. By controlling the temperature of the engine, the excavator thermostat can reduce the use of engine cooling water, thereby reducing engine wear and damage.
2. Working principle of excavator thermostat
The working principle of the excavator thermostat is relatively simple and is mainly divided into two steps:
1. Check the temperature
The excavator thermostat detects the temperature of the engine cooling water in real time through an internal sensor. When the temperature exceeds the set range, the excavator thermostat will automatically trigger the heating and cooling mechanism.
2. Control air supply and exhaust
The excavator thermostat controls the air supply and exhaust through a heating and cooling mechanism to adjust the engine temperature. When the temperature is too high, the excavator thermostat will control the air supply to increase the heat dissipation of the cooling water and reduce the engine temperature. On the contrary, when the temperature is too low, the excavator thermostat will reduce the air supply and increase the engine temperature.
In short, the excavator thermostat is an essential component of the excavator engine. Its function is to monitor and control the engine temperature to ensure the normal operation of the engine and extend its service life.
