调节阀电液执行机构在煤化工中的应用

Application of Control Valve Electrohydraulic Actuator in Coal Chemical Industry

针对调节阀执行机构的主要类型、组成、工作原理和特点,讨论了不同类型执行机构的适用范围,重点介绍了神华宁夏煤业集团有限责任公司自主研发的环球电液控制机构的性能特点和使用情况,举例说明了电液执行机构在煤化工领域的应用,其具有输出力矩大、响应速度快、抗偏离能力强、投资较低的特点,在对现有装置手阀改造方面取得了显著的经济效益。

This paper discusses the application scope of different electrohydraulic actuators based on major types,components, working principles and characteristics of control valve actuators. Performance,features and applications of the electrohydraulic actuator developed independently by Ningxia Shenhua Coal Group. Co, Ltd. are specially introduced. The paper also explains the application of electrohydraulic actuator in coal chemical industry by discussing several real examples. The electrohydraulic actuator is characterized by large output torque, quick response, strong deviation resistance, low cost and so on, which help to gain significant economic benefits in the aspect of hand valve reforming.
