OPERATING PERFORMANCE''''S SIMULATION OF A NEW ENERGY-SAVING CONTROLLABLE DIAMETER AND VARIABLE TORQUE PUMPING UNIT

In this paper,one new energy-saving controllable diameter and variable torque pumping unit (CDVTPU) and its structural characteristic and operating principle are introduced.The geometrical,kinematic models and the operating performance's realistic models of CDVTPU are also established.On this basis,the operating performance's simulated software of the pumping unit is developed,and the simulating analysis of the pumping unit's kinematic principle,crank axle's output torque and the counterbalance effect as well is realized.After understanding fully the CDVTPU's working and energy-saving theory,the theoretical foundation and scientific method are provided for farther optimizing the CDVTPU's structure,configuring the pumping unit reasonably,improving working efficiency of pumping system and exploring advanced pumping unit.
