    摘要:

    为研究稠油开采中常规螺杆泵定子衬套的接触磨损,通过摩擦试验研究在不同转速和载荷下,定子衬套所用丁腈橡胶在高温含砂稠油中摩擦因数的变化规律。实验结果表明:定子橡胶的摩擦因数随着转数的增加先增大后减小,之后几乎保持不变;随着法向载荷的增大,定子橡胶的摩擦因数先减小后增大。以试验测得的摩擦因数为依据,利用有限元分析方法,对高温含砂稠油中螺杆泵定转子之间的接触进行分析,研究摩擦因数、过盈量、工作压差等因素对定子衬套接触磨损的影响。分析结果表明:衬套的剪应变随着衬套摩擦因数、过盈量、工作压差的增大而增大;位移量随着摩擦因数的增大而减小,随着过盈量的增大而增大;工作压差不但影响定子衬套内轮廓接触位置的磨损,还加剧衬套外壁面的黏着磨损。

    Abstract:

    In order to study the contact wear of stator bushing of conventional progressive cavity pump (PCP) in heavy oil extraction,the variation of friction coefficient of nitrile butadiene rubber(NBR) for stator in the high temperature and sandcontaining crude oil under different speed and load was studied by friction and wear test.The experimental results show that the friction coefficient of NBR for stator is increased firstly and then decreased as the number of revolutions increases,and then remains almost unchanged.However,the friction coefficient is decreased firstly and then increased with the increasing of the normal load.Based on the friction coefficient measured by experiment,the contact analysis of progressive cavity pump’s stator and rotor was carried out by finite element method to study the influence of friction coefficient,interference and working pressure difference on the wear of stator bushing.The results show that the shear strain of the stator bushing is increased with the increasing of friction coefficient,interference and working pressure difference.The displacement is decreased with the increasing of friction coefficient while increases with the increasing of interference.The working differential pressure not only affects the wear of stator bushing inner wall contact position,but also aggravates the adhesive wear of stator bushing outer wall.
