It is responsible for increasing the working pressure of the coolant in the circulation system and maintaining the coolant circulation between the relevant parts of the engine to prevent the engine from running at too high an temperature. The working principle of the cooling water pump is based on the action of centrifugal force. When the water pump impeller rotates, the coolant is sucked into the water chamber and rotates with the impeller. Under the action of centrifugal force, the coolant is thrown into the water outlet chamber and transported to the engine's cooling system through the water outlet pipe. The existing automobile cooling water pump basically meets the needs, but there are still certain defects.
