油管套丝自动线执行元件行程程序的设计

Design of the Running Program for the Actuators on an Automated Tubing Thread Dieing Line

油管套丝自动线执行元件的所谓三种工作状态有两个含义:1.作旋转运动的气马达或电动机有正转、反转和停止三种工作状态;2.作直线运动的气缸有活塞伸出、缩回和中途停止三种工作状态。文中着重对油管套丝自动线含三种工作状态执行元件行程程序的设计方法进行了探讨。

The actuators on an automated tubing thread dieing lineshould accomplish three working operation in two respects, i.e. clockwise and counter--clockwise rotation and standstill forthe air motor or electromotor; Stretching out, drawing backand standing still halfway for the piston in the cylinder.This article lays emphasis on discussing the method of design-ing a running program for the actuators to meet the above-mentioned requirements.
