The car engine widely uses the centrifugal pump. The basic structure consists of a pump shell, connecting plate or belt pulley, water pump shaft and bearing or bearings, water pump impeller and the water seal device and other parts, is the main part of the vehicle. Working principle     The engine drives the pump bearing and an impeller to rotate by a belt pulley, the coolant pump is driven impeller to rotate together, under the action of centrifugal force was thrown to the pump shell edge, at the same time produce a certain pressure, and then from a channel or pipe outflow. At the center of the impeller coolant is thrown out and the pressure is reduced, the cooling liquid tank in the inlet of the pump and the impeller center differential pressure under the action of water is sucked into the impeller, realize the reciprocating circulating cooling liquid.     Grease the bearing support the water pump shaft, so to prevent leakage of cooling fluid to grease caused by grease emulsification, but also to prevent leakage of lubricating grease. Water pump seal leakage prevention measures of water seal and gasket. Seal seal ring and the shaft through the interference fit between the impeller and bearings, seal static sealing seat tightly pressed on the pump casing, so as to achieve the purpose of cooling liquid seal.     The pump casing through a sealing gasket is connected with the engine, and supporting bearings and other moving parts. The pump casing and drain, located between the seal and the bearing. Once the coolant leakage water, can be discharged from a drain hole, in order to prevent the cooling fluid into the bearing cavity and destruction of bearing lubrication and cause component corrosion. If the engine is stopped still coolant leaks out, indicates that the water has been damaged. Automotive engine ENGINE COOLANT PUMP FOR FITNISSAN GC22 D21 E24 E23 F22 Z24 Z18 Z22 Z20 21010-P7588 1992-2010
