About Products:

The excavator engine thermostat refers to a cooling intensity adjustment device installed in the excavator engine cooling system. Its main function is to allow the engine to quickly heat up during the cold start phase and quickly pass through the cold start phase to prevent the engine from working at a lower temperature for a long time and aggravating wear.

The working principle of the excavator engine thermostat is as follows:

1. At low temperatures: The thermostat is closed and the engine's cooling system performs a small cycle. The coolant only circulates inside the engine without passing through the radiator, which allows the engine to heat up quickly.

2. Reaching a specific temperature: As the engine temperature rises, the thermostat will gradually open and begin to allow part of the coolant to flow through the radiator for large circulation, thereby maintaining the normal operating temperature of the engine.

3. After the temperature stabilizes: When the engine reaches normal operating temperature, the thermostat is fully opened and all coolant is circulated through the radiator to prevent the engine from overheating.

The main functions of the thermostat include:

1. Rapid heating: Helps the engine warm up quickly in cold weather.

2. Keep the temperature stable: Ensure the engine operates within a suitable temperature range to improve fuel efficiency and performance.

3. Reduce wear and tear: Prevent the engine from running under overheating or overcooling conditions and reduce the wear and tear of parts.

In short, the thermostat achieves effective control of the engine temperature by adjusting the circulation path of the cooling system.
