一种细长螺杆转子的旋切加工工艺

A New Workmanship for Swirl Peeling of Long and Thin Rotors

通过分析、研究 1.2 RPEO2 9PO核电站用单螺杆泵转子的结构特点 ,提出了旋风切削加工单螺杆泵细长转子的工艺方法。经过实践证明 ,该工艺方法能较好地解决旋风切削加工单螺杆泵细长转子发痉的难题 ,能够可靠地保证核电站用单螺杆泵转子旋风切削加工要求 ,可以在多级细长转子旋风切削加工中推广应用。

After making analysis of the structure of the rotors of screw pumps 1.2RPEO29PO for unclear power station, a new workmanship of swirl peeling method was propose d for machining the long rotor. And proved by practice, this workmanship has sol ved the problems in swirling peeling long and thin rotors. It can fully meet the requirement of swirl peeling for rotors of screw pumps for unclear power statio n and can be extensively promoted in swirl peeling multistage long and thin roto rs.
