Optimization design of planetary reducer for 2Z-V ESPCPS

The key design for Electric Submersible Progressing Cavity Pump(ESPCPS)is to satisfy the power input of screw pump for higher torsion and lower rotation rate.According to the experiments and research,the designing difficulty of the whole system is the mechanical reducer.Therefore,optimization design for 2Z-V planetary drive with small teeth difference is done based on the design requirement of well conditions in Shengli Oilfield.Based on the mathematical model established,the method of layered network with higher stability and faster speed in the process of optimization design is selected to optimize and better performance parameter is got with obvious optimization result.For the first time,an integrated performance coefficient R is proposed,which solves the problem of reducer’s performance comparison for ESPCPS with kinds of different structures,various units under different working conditions.
