Development and application of polish rod vibration absorber

Existing polish rods of pump units can not effectively absorb vibration, thus they often break and damage packing sets. A polish rod vibration absorber is developed in order to sole these problems. It has simple structure and can effectively absorb vibration of polish rods, thus can improve their stability. Field experiment shows that this kind of vibration absorber can prolong service life of polish rod of pump units and packing set
