Operating principle of rod pumps:

Rod pump is equipped with a supporting joint, support joint is connected on the tubing, rod pump plunger is connected on the sucker rod string, and is fixed on the supporting joint through the sucker rod string to the tubing, the plunger along with the sucker rod string's up and down reciprocating movement achieve pumping work. when pump appear quality problem, you needn't put forward tubing, only through the sucker rod pull the whole pump from the wel and operation is simple.
