摘　　要：根据单螺杆泵定子骨线及其等距曲线的形成原理,利用Matlab软件对单螺杆泵定子骨线打扣现象进行了深入剖析,并利用数值法绘出了单螺杆泵定子头数、变幅系数和不打扣条件下的最大等距半径之间的关系图形。结果表明:当定子头数确定时,变幅系数与不打扣最大等距半径的关系曲线为递减规律;当变幅系数确定时,定子头数越小,允许的不打扣半径越大。According to formation mechanism of stator skeleton lines and its isometric profiles of screw pump,the phenomenon of Dozen buckle of bone line of single screw pump stator has been analyzed by mathematical software Matlab,the relationship between the different number of single screw pump stator,the radius variation ratio and the radius of the maximum isometric under the condition of no dozen buckle has been painted out.The results show that：when the stator head is determined,the radius variation ratio and the radius of the maximum isometric show a decreasing trend;when the radius variation ratio is determined,the fewer the number of stator head,the larger the radius.
