Optimal Design And Virtual Reality Modeling Of Electrical Submersible-Motor-Driven Progressive Cavity Pumping Reducer

Along with the oil industry development, the mine shaft actuation extraction system obtains wide attention and due to restrictions of the tubing diameter, it has become a problem to increase the torque. The system needs a set of apparatus to increase the torque and to cut down the speed. This article takes 2K-H kind of two-stage planetary transmission through the contrast analysis. The main results are as follows:According to the extraction environment, 2K-H kind of two-stage planetary transmission has been taken as the screw rod pump mine shaft drive, which has smaller diameter and larger range of the transmission ratio.Considering all the factors, such as stator and the rotor initial tight, thermal expansion of the stator rubber, swelling expansion of the stator rubber, ANSYS finite element analysis tool has been used to simulate the contact state between the stator and the rotor. Calculation method of the friction torque has been improved and calculation precision has been improved.Electric submersible screw pump drives and drive system has been simplified to a single degree of freedom rigid rotor dynamics system and established of electric submersible screw pump system dynamic simulation model of the startup process. Analysis results show that the electric submersible screw pump reducer output torque of the dynamic load factor has been around 1.6 optional, and in the electric submersible screw pump drive system components is the structural design of the factors that can not be ignored.Reducer in the criteria for the design of the smallest, from the center gear and the size of the planetary gear reducer drive and minimum as the optimum design parameters of the objective function, considering constraints and strength reducer transmission constraints, transmission reducer mathematical optimization model has been established .Application of MATLAB optimization toolbox casingψ138mm completed, the power of 10kW, the transmission ratio of the reducer 10 to optimize the design of transmission parameters.ANSYS has been used as finite element analysis of components to the key parts of the reducer and to check gear contact stress in meshing process stress. In the finite element method based on the results, and structure parameters has been ultimately determined and three-dimensional modeling has been finished .
