Torque Loads And Plunger Displacement From The Dynagraph

In order to clarify the present discussion, it is thought wise to review briefly the discussion and demonstration of The dynagraph animator, to help you visualize the properties of sucker rods, and the significance of the dynagraph. The dynagraph of an oil well is no more than a graphical record of force recorded against a distance from some starting point. We usually consider the lowest point in the polished rod travel, which is the beginning of the point. The dynamometer is usually supplied with a vibrating device whereby the time element be separately recorded with respect to the starting point.
