Structure and working principle of water pump in forklift cooling system what is the structure of water pump, and how does it work?
(1) Structural composition of water pump:
The cooling water pump of the engine generally adopts a centrifugal water pump, which is mainly composed of pump body and pump shaft Impeller, water seal, water inlet pipe, etc.
(2) Working conditions:
Driven by the crankshaft, the belt pulley outside the pump drives the impeller to rotate in the pump body through the water pump shaft to generate rotating centrifugal force and forms a partial vacuum at the water inlet pipe. The water enters the center of the impeller, and the water is thrown to the inner wall of the pump body by the impeller blade. Due to the increased flow rate of water, a certain pressure is generated and then flows to the water jacket of the cylinder block through the water outlet of the water pump. Realize the water circulation of the cooling system.
After the water pump has been used for a long time, when the impeller is corroded and rusted and can no longer work, some engine cooling water pumps can separate the water pump base from the water pump head. If the water pump base is not damaged, you can ask the forklift parts Seller whether there is a corresponding water pump head to replace to save the cost of replacing parts as much as possible.
