采油螺杆泵橡胶定子加速疲劳模拟试验装置的研制
|
摘要
为了等效、加速模拟螺杆泵橡胶定子的疲劳情况,探究其疲劳寿命,研制了一台采油螺杆泵橡胶定子加速疲劳模拟试验装置。通过螺杆泵实际工况和力学特性分析,对该装置关键零部件进行结构设计,确定了十六齿梅花状金属转子与橡胶块定子的模拟结构和过盈量调整装置结构。该装置能够实现不同温度、过盈量、转速和介质条件下的螺杆泵橡胶定子疲劳模拟试验,试验加速160倍。
In order to equivalently simulate the accelerated fatigue of the rubber stator of PCP( progressive cavity pump) and explore its fatigue life,an accelerated fatigue simulation test device for the rubber stator of an oil extraction screw pump was developed. Through analyzing the actual working conditions and mechanical characteristics of PCP and the structural design of the key parts of the device,the simulation structure of 16-tooth plum-shaped metal rotor and rubber block stator was confirmed. This device can realize fatigue simulation test of the rubber stator of PCP under different temperatures,interferences,rotation speeds and medium conditions and can accelerate the test by 160 times.
