全断面通道式自动风窗研究与应用

Research of automatic passageway type air regulator with full section and its application

针对传统风窗调节周期长、精度低等问题,研发了由支撑框架、气动马达、推杆、门体、导流板和旋转编码器为主要组成部分的全断面通道式自动风窗,介绍了风窗过风面积精确测控原理。该自动风窗在压缩空气的压能作用下,气动马达高速旋转,通过推杆传动带动门体和导流板运动,实现了风窗面积的快速调节;利用旋转编码器记录气动马达转数。现场应用表明,该自动风窗过风面积调节最大误差为0.385%,完成1次面积调节耗时小于60s。

For problems of long adjustment time and low adjustment precision of traditional air regulator,an automatic passageway air regulator with full section was developed,and accurate measurement and control principle of air section of the air regulator was introduced.The air regulator is composed of a supporting frame,apneumatic motor,apush rod,a door body,aguide plate and a rotary encoder.Under the pressure of compressed air,the pneumatic motor rotates at high speed and drives the push rod to push the door body and the guide plate to move,so as to realize rapid adjustment of air regulator area.The rotary encoder records revolutions of the pneumatic motor.The field application shows that the maximum error of air area adjustment is 0.385%,and area adjustment time is less than 60 s.
