According to the service of single screw pump and the characteristics of double thread screw, several methods for machining double thread screw are analyzed, and it is proposed numerically controlled turning method being adopted. 针对单螺杆泵的使用情况和双线螺杆本身的特点,分析了几种加工方法,在说明双线螺杆铣削加工中存在的问题后,提出了采用数控车削加工方法。
The sealing principle of sealing cavity in single thread twin screw pump is the same as that in double thread twin screw pump. 单头双螺杆泵与双头双螺杆泵密封腔的密封原理相同。
