井下平衡风门气动控制系统.docVIP

B前，随着我国经济的迅猛发展，对于资源的需求量越来越大，而当今的资源大部分 还是来自矿产。因此对采矿业也有了更高要求，不仅有数量和速度上的要求而且对于安全 性也有了更高的要求。井下通风是确保井下安全生产的一个重要环节，通风设施中隔断 风流的设施主要是风门。因此风门的研宂和设计对井下安全生产具有重要的意义。 木文主要是介绍井下平衡风门气动控制系统设计过程，与以往的风门相比该风门的 主耍优点是：因为两扇风门的幵启方向是相反的，风门W侧的风压平衡故开启风门所需的 力小，同时该风门安装了一套自动控制系统，从而实现了风门的自动开启与闭合；设计过 程主要包括风门的结构设计和风门的控制系统设计，在风门的结构设计主要是利用四连杆 机构实现风门的反向开启；控制系统的设计主要利用数字电路、低压电路与气动控制系统 结合实现风门的自动开闭同时保证两道风门的互锁关系。 井卜*平衡风门的设计大大节省了人力和操作时间，必将得到越來越广泛的应用。 关键词：风门；平衡风门；通风；自动控制 Abstract At present，with the rapid development of our economy, the growing demand for resources， and the most from mineral resources or. Therefore for mining a higher requirement，not only quantity and the speed of the requirements for safety and also had higher requirements. Underground mine ventilation is to ensure the safety in production, is an important link in the partition of ventilation facilities is mainly throttle.in airflow. So air door the research and design of mine safety production has the vital significance. This paper is mainly introduced air door in pneumatic control system in balance with the previous design process, compared with the main applications air door in advantage: Because of the two opposite direction is being opened, the wind is being opened on both sides of the balance of the force needed after being small，meanwhile，the installation of a set of automatic control system，so as to realize the automatic open and closed air door，Design process including applications in the structural design and the control system design，after being in the structure design is mainly realized using 4-linkage mechanism of reverse air door in open; The design of control system using digital circuit, low-voltage circuit and pneumatic control system with the open and close automatically after realizing that two applications and interlock relationship. The design of underground balance being saved the manpower and operation time, will get more and more widely. Keywords: air door; balance air door； Ventilated； Automatic control. 目录 TOC
