SEEPEX Coupling Rod screw pump Plug in shaft Progressing Cavity Pump Drive Shaft

The introduction of screw pump coupling rod

1.The connecting Rod Group consists of connecting rod, universal joint,coupling rod, guide bush, rubber rings, and a rubber sheath, connecting rod pin, retaining sleeve,steel wire rings, drive shaft, etc.

 2 The connecting Rod Group is in addition to withstanding not only the force of drive shaft, but also to bear the force of its own swinging longitudinal and transverse, the size and direction of these forces are cyclical, so the connecting rods are subjected to alternating loads such as compression and stretching.The size and direction of these forces are cyclical, so the connecting rods are subjected to force of compression, stretching and so on.

3 The coupling rod must have sufficient fatigue strength and structural stiffness. If the fatigue strength is insufficient, it will lead to break the connecting rod body or connecting rod interface, and then produce the major accident whole machine damage.

4 If the rigidity of the connecting rod is not enough, it will cause the bending deformation of the rod body and the universal joint, resulting in the eccentric grinding of the coupling rod, guide bush, thecoupling rod bush, etc.

Function of connecting rod:

The connecting rod is used to connect the drive shaft and the rotor , and transmit the actuator force to the rotor, thus driving the rotor to rotate the motion. According to the requirements of the media, the joint shaft can be installed with a broken bridge aid flow device

Material of connecting rod:

The main damage form of the connecting rod is fatigue fracture and excessive deformation. Generally, the fatigue fracture area is three high stress areas on the connecting rod. The working condition of the connecting rod requires that the connecting rod has high strength and anti-fatigue performance, and it also requires sufficient rigidity and toughness. Traditionally, the materials used in the process of connecting rod are 304, 316L, 40Cr, 2Cr13, 2205, 904L and so on.

The material of coupling rod we commonly used :

SUS304 ;  SUS316;  2Cr13, 40Cr, 2205 , 904L etc.
