Abstract

In order to understanding thoroughly the operating characteristics of dual horsehead pumping unit, with 8-type machine as the research object, we compared the conventional pumping unit and dual horsehead pumping unit about movement characteristics, loading characteristics and torque characteristics. The theory analysis results show that dual horsehead pumping unit have some good characteristics such as low impact, small dynamic load, small torque fluctuations, small balance weight and matching small motor power.
