Introduction of Marine Pump Shaft
The function of the pump shaft is to connect the motor with the coupling and transmit the torque of the motor to the impeller, so it is the main component for transmitting mechanical energy.
Gear Pump Shafts of Different Materials
①Gray iron is a high-strength cast iron, the matrix is pearlite, and the strength, wear resistance, heat resistance are good, and the shock absorption is also good; the casting performance is good. Used in important castings in general machinery manufacturing.
②304 stainless steel has good corrosion resistance, longer durability than ordinary steel, good corrosion resistance and high strength. It is also resistant to high temperature oxidation and high strength, so it can resist fire; Easy to shape; Because there is no need for surface treatment, it is simple and easy to maintain; Clean, high finish; Good welding performance.
③316 stainless steel is greatly improved in corrosion resistance and high temperature strength due to the addition of Mo element. The high temperature resistance can reach 1200-1300 degrees, and it can be used under harsh conditions.
