Why is the Thermostat Prone to Failure?
1 Answers
Due to prolonged warm-up time, electric flatbed trucks operate at lower water temperatures, causing combustion gases to react with condensed water on the cylinder walls, forming acidic substances that corrode the cylinders and lead to thermostat failure. Below is an introduction to the thermostat: 1. Device Introduction: The thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature, altering the water circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within an appropriate temperature range. 2. Working Principle: The most commonly used thermostat is the wax-type thermostat. When the coolant temperature is below the specified value, the refined paraffin inside the thermostat's temperature-sensing body remains solid, and the thermostat valve, under the action of a spring, closes the passage between the engine and the radiator. The coolant then returns to the engine via the water pump, initiating a small internal circulation within the engine.
