摘要
随着油气资源开采深度的增加,常规螺杆马达无法解决其组成部件的橡胶衬套高温失效问题,设计全金属螺杆马达具有重要的意义。本文选用7LZ178全金属螺杆马达,从其定子、转子端面线型设计与定子、转子间隙配比2个方面分析其对于马达的性能输出的影响。从螺杆马达端面线型入手,对比分析了4种线型形成原理以及优缺点。选用普通内摆型定、转子线型建立了三维模型,进行流体仿真,简要分析了螺杆马达随定子、转子间隙改变压力、扭矩等输出参数变化情况。探究全金属螺杆马达在不同间隙值下的压降变化趋势,为确定对应设计参数下螺杆马达间隙配合的最佳范围提供了参考意义。
With the increase of mining output of shallow and middle oil and gas resources,oil and gas resources exploitation gradually extends to deep and ultra deep layers.With the increase of depth,for conventional screw motors,it is impossible to solve the problem of high temperature failure of rubber bushings of its components.Therefore,designing an all metal screw motor is of great significance.This article selects the 7LZ178 all metal screw motor and analyzes its impact on the performance output of the motor from two aspects:the linear design of the stator and rotor end faces of the screw motor and the clearance ratio of the stator and rotor of the all metal screw motor.This article starts with the end face shape of the screw motor and compares and analyzes the formation principles of four types of shape,as well as the advantages and disadvantages of the four types of shape.A three‑dimensional model was established using a common internal swing type stator and rotor line shape for fluid simulation.The changes in output parameters such as pressure and torque of the screw motor with changes in stator and rotor clearances were briefly analyzed.Exploring the pressure drop variation trend of metal screw motors under different clearance values provides reference significance for determining the optimal range of clearance fit of screw motors under corresponding design parameters.
