【Abstract】 Front mounted pumping units have adopted the geometric structure of balanced torque and the upstroke time longer than the downstroke time. Therefore, it can reduce acceleration and maximum load on polished rod at same time. Methods for calculating geometric parameters and kinematic and dynamic analysis for the units are discussed. The job of calculation is programmed on the computer through the BASIC. Block-diagram and illustration of use is given in this paper. And by taking CYJ14-6-105HB pumping unit as an example, the calculation has been made via the program and results obtained which are up to what is actually happening.更多还原
