The key temperature sensor thermostat of diesel generator set is wax thermostat. When the cooling temperature is lower than the standard value, the thermostat will feel the fine paraffin in the body: solid. The thermostat valve closes the channel between the engine and the radiator under the action of the spring, and the refrigerant returns to the engine to conduct a small cycle of the engine according to the water pump. When the temperature of the coolant reaches the limit value, the paraffin begins to melt and slowly turns into liquid, the volume increases and the hose shrinks. When the hose shrinks, push up and down to open the gate valve. At this time, the refrigerant flows back to the engine according to the radiator and thermostat valves to start a large cycle.
