| 摘 要： | 利用三维有限元模型计算螺杆泵在过盈条件下的转子运动轨迹,分析在液压条件下液压力对定、转子相互作用的影响,得到液压条件下转子的运动规律,解释螺杆泵在运行过程中转子运动轨迹发生变化的机制。以改善螺杆泵的运行特性、降低扭矩为目的,提出同时改变螺杆泵转子节圆直径与偏心距的型线优化设计方法。结果表明,新方法能够较好地修正螺杆泵转子在定子内部的运动轨迹,提高螺杆泵的举升特性,延长螺杆泵的使用寿命。 |

| Abstract: | The three dimensional finite element analysis model was conducted to study the rotor’s movement locus in the interference fit condition.It was conducted to simulate the contact and interaction between the stator and rotor under the hydraulic condition.The rotor’s movement locus under pressure was gotten.The mechanism of the changed rotor’s movement locus was explained.For improving the movement characteristic of progressive cavity pump and declining the torque,a locus optimization method was given by which pitch circle diameter and eccentricity of rotor can be changed.The results show that this method can fix the trajectory of rotor inside the stator,optimize the working characteristic and extend the life of progressive cavity pump. |
| Keywords: | progressive cavity pump rotor stator three dimensional simulation finite element analysis locus optimization |
