What is a
universal joint assembly of a progressive cavity pump?
When the pump is running, the rotor makes planetary motion, and its axis is not on the same straight line as the axis of the driving power source. In this way, special components must be designed between the rotor and the drive shaft so that the drive shaft of the power source can drive the rotor to complete such planetary motion. This special component is called a universal joint.
In this way, the pump drives the universal joint by the drive shaft, and then the rotor is driven by the universal joint to complete the planetary rotation around the axis of the stator.
