What are the requirements for making pump shaft materials?
The main role of the axis of the centrifugal pump is to transfer power, support impeller in the work position, the amount of normal operation. One end of the shaft is connected with the motor shaft through a coupling, and the other end supports the impeller to rotate. The shaft is provided with bearings, axial sealing parts and the like.
. In corrosion resistant pumps, that is used to transport acid, alkali and other corrosive medium pump, the pump shaft material is generally lCr18N19, lCr18Ni9Ti and other stainless steel.
The pump shaft is usually made of 45 steel and quenched and tempered. The pump shaft material is 40Cr and quenched and tempered in the pump conveying weak corrosive medium such as salt solution.
