摘要
通过理论分析,得出了单螺杆泵压力的产生和传递规律。采用有限元方法,建立了单螺杆泵的二维模型,分析了螺杆泵定子橡胶与转子间腔体压差、腔体压力以及过盈量对接触压力的影响,得出了压差与接触压力、腔体内压力与接触压力和最大密封压力及过盈量与最大压力的关系。结果表明:压差的增大使接触压力增大;腔体内压力的增大使接触压力减小,最大密封压力降低;过盈量的增加使螺杆泵的最大压力增大。
The rules of the single progressive cavity pump pressure modeling and transfering were studied based on the theory analysis.With the finite element analysis,the two-dimension modeling of the single progressive cavity pump was constituted,the influences of pressure difference between the progressive cavity pump stator rubber and the rotor cavity,cavity pressure and the interference fit degree on the contacting pressure were analyzed.The relations of pressure difference and contacting pressure,cavity inner pr...
