Cooling water pump

Of the cooling water pressure to speed up the circulation of cooling water, cooling to ensure reliability. Vehicle Engine multi-centrifugal pumps, centrifugal pumps has a simple structure, small size, large displacement, and convenient maintenance. Mainly by the pump centrifugal pump, impeller and pump shaft component, the impeller is generally radial or backward bending, the number usually 6-9 pieces. When the impeller spins, water pump impeller in the water is driven with the rotation, the centrifugal force, the water left behind the edge of the impeller, and then by the casing and impeller tangential direction of the outlet pipe into the pressure delivered to the engine water kit. At the same time, reduce the pressure on the center of impeller, the water in the radiator pipes have been sucked into the impeller into the central part. The role of this continuous, so that the water in the cooling water circulating constantly. If the pump stops working for some reason, the cooling water is still flowing from between the impeller blades, to heat cycle and he will not overheat very quickly.
