What are the structural characteristics of diesel water pump

The main parts of the diesel engine cooling system include water pumps, fans, radiator and thermostats. The pump is one of the main components in the cooling engine cooling system for compulsory circulating water. The role of the pump is to pressurize the cooling solution to ensure that it circulates in the cooling system, and its working conditions directly affect the reliability of the engine cooling. Therefore, the maintenance of the pump must be attached enough. The failure of the pump is usually leakage caused by the damage of the water seal, and the bearing failure causes the rotation to be abnormal or an abnormal noise. When the engine is overheating, the first thing to pay attention to is the pump belt to check whether the belt is broken or loose.
The diesel engine cooling pump is a centrifugal pump, which is driven by a crankshaft belt wheel drive in the gear chamber of the front end of the diesel engine. Among them, the snail shell of the pump is above the gear room, which is integrated with the gear chamber. The impeller of the pump is cast iron.
