双热源作用下螺杆泵定子非稳态温度场数值模拟
Numerical simulation on unsteady temperature field of progressive cavity pump stator with double heat source
摘要
Abstract
In order to investigate the problem of high-temperature destruction in oil and gas field production, based on the auto-mobile sliding theory, a single direction decoupling solution strategy was proposed for determining temperature distribution and heat dispersion performance in the stator of the GLB500 and DGLB500 pumps. The stator temperature increase was analyzed over different interference, rotational speed and friction coefficient. The results show that the stator temperature field of progressive cavity pumps distributes symmetrically along the long axis, and the highest temperature point locates at the center of the thick wall of stator rubber bushing. When the friction heat is considered, the highest temperature point shifts to the stator center along the direction of the short axis. The heat dispersion performance of the iso-wall thickness progressive cavity pump is good and more uniform. And the dispersion performance of the conventional progressive cavity pump in long axis is better than the short one. When the friction heat is neglected, the temperature increase of stator correlates with rotational speed positively, it increases in parabolic trend along with interference. Under the effect of double heat sources, the temperature increase of stator rises sharply with interference and rotational speed, moreover, the iso-wall thickness progressive cavity pump is more sensitive to them.关键词
