摘要
基于流体网络解耦方法研究了潜油电机内部循环油路对潜油电机传热的影响。根据潜油电机轴向流场的重复性,以气隙、转轴内腔和扶正轴承甩油孔处的流体流速和压力之间的关系作为边界条件,对潜油电机全域流体场进行分区解耦,对局部典型区域通过三维流场分析,得到不含循环油路、油路垂直和油路重合情况下的潜油电机内部各部件温度的分布情况以及电机内部流体的流动状态,并给出了循环油路对潜油电机温度场和电机内部流体的流动特性的影响。通过与样机的试验数据对比分析,验证了流体网络分区解耦方法的有效性。为研究特殊结构电机的全域流体场及其热效应提供了理论依据。
The influence of the oil circulation system inside submersible motor on heat transfer of submersible motor was studied by fluid network decoupling method. According to the repeatability of the axial flow field of submersible motor,the loss pressure drop and flow rate at the end of a single motor were used as the control conditions,so that the whole motor model can decouple into a single motor. By analyzing the dimensional flow field of the typical region of motor,the temperature of the motor and the fluid characteristic of the fluid inside the motor were obtained under non oil circulation system,vertical oil circulation system and straight oil circulation system,and the influence of the oil circulation system inside submersible motor on heat transfer were explored. Compared with test data from the prototype,it shows that the method of fluid network partition decoupling is proved to be effective. The method provides a theoretical basis for the whole fluid field and thermal effect of special structure motor research.
