摘要
根据采油螺杆泵定子几何物理特性,对螺杆泵工况进行了合理的假设,建立了螺杆泵定子工作状态下的力学、传热数学模型。以常规GLB500—14型螺杆泵定子为例,利用有限元分析方法进行了定子力学场、温度场的耦合数值模拟计算,获得了特定条件下的定子内部稳态温度场分布情况,给出了温度场分布云图。通过计算结果验证,认为数值计算模拟结果较真实地反映了定子的传热状况,可为螺杆泵定子的研制开发提供可靠的理论依据。
According to the geometric and physical properties of a PCP stator, operation situation of the stator is assumed reasonably, a mechanical and mathematical model of heat transfer is established under the operation condition of PCP stator and by taking conventional GLB500-14 PCP stator for example, the coupling numerical simulation of mechanical field, temperature field are calculated by finite element analysis, steady distribution of the temperature field inside the stator is achieved under a special condition and distributional nephogram of temperature field is presented. The result is demonstrated that the heat transfer situation of the stator can be properly reflected by using the simulation result, by which theoretical bases can be provided for the development of PCP stators.
