摘要: 气液两相流装置针对电力、煤炭、冶金、石油、化工等行业，研究并推广的一种全新结构的设备。气液两相流的检测能保证气液两相流的正常工作,以及发生故障时对于导致故障原因的查找。本次的设计内容是运用PLC控制，有两个电机分别带动驱动杆的前进和旋转，使得让安装在驱动杆顶部的高清CCD传感器能边旋转边前进，探测气液两相流内部的状态。
由于横向的进给距离为6米，相对于给进设备的尺寸较长，所以我们把驱动杆平均分成751段，每段之间运用具有螺纹的连接器进行连接。驱动杆的螺纹部分使用铜材料。
电机的分布分别是一上一下型，上面的电机1连接着有两个半圆组成的夹紧机构用来夹紧驱动杆，上面的电机1安装一块安装在导轨上的甲板上用来固定电机。下面的电机2通过联轴器连接两端固定的滚珠丝杆，滚珠丝杆上的螺母连接着甲板的下部分，甲板的上半部分连接这上面的电机1。36293
导轨我们安放在比电机2稍高的地方用于甲板上电机1的轴向移动。

Abstract: the gas-liquid two phase flow device for electric power, coal, metallurgy, petroleum, chemical industry, research and promotion of a new structure of the equipment. Gas-liquid two phase flow of gas liquid two phase flow detection can guarantee the normal work, and fails to lead to find the cause of the problem. The design content is to use PLC control, there are two motor drive the actuating arm forward and respectively, make installed in high-definition CCD sensor on the top of the drive rod rotation while forward, detection of gas liquid two phase flow within the state.
Due to the transverse feed distance is 6 meters, relative to the size of the feeding device is longer, so we put the driveshaft is pided into six paragraphs, on average every has a threaded connector for connection between the application. Drive rod threaded portion USES copper materials.
Distribution respectively is a type of motor, the motor 1 connected with two semicircle of fastening device used for clamping actuating arm, the above motor installed 1 piece on the guide rail used for fixed motor on the deck.The motor below 2 through coupling connection at both ends fixed ball screw, ball screw nut connected on the lower part of the deck, the first half of the deck to connect the motor on this one.
Guide the place where we placed a little higher than 2 motor used for the deck motor 1 axial movement.
Keywords: PLC, rotating straight forwar
