8237-1246 超速安全装置

8237-1246 WOODWARD 伺服操控器
8237-1246型是Woodward ProTech-Gll系列的一部分。它是一种超速检测体系,可装备为与多种类型的涡轮机-起使用。假如它感应到水轮机、蒸汽轮机和燃气轮机加速过度，它可以安全地封闭它们。除了加速度检测,它还有MPU检测。8237-1246型还耐硫、H2S和S02气体。它采用三重模块化设计便于在产品运转中替换-一个部件
ProTech-Gll是-种超速安全设备,设计用于在感应到超速或超加速事件时安全封闭各种尺寸的蒸汽、燃气和水轮机。
伍德沃德WOODWARD电流压力转换器(CPC)为操控蒸汽阀、燃料润和(咸相应的伺服机构而设计，它将4-20mA操控信号线性成份额地转换为油压输出。CPC可与许多电控设备匹配使用，如WOODWARD MicroNet或505系列操控器等。它适用于压力型伺服体系或单效果动力缸。CPC也适用于旧机改造项目。
币德沃德Woodward TG-13和TG-17是机械液压有差式调速器，用来操控汽轮机,这种不需同步(等速)方式运转的地方。TG-13和TG-17调速器输出轴的最大旋转视点为40”，从空载到满载推荐的转角行程为调速器全行程的213，WOODWARDTG-13E和TG-17E电液执行器均自备独立油源，适用于需要无差调速、负荷分配或其他功能的蒸汽透平，并与WOODWARD一切的电子操控器及附件兼容。
伍德沃德WOODWARD伺服方位操控器(SPC)是一个同服阀驱动器，它接受来自体系操控器的DeviceNet或4-20mA方位指令信号，并能精确定位份额型或积分型伺服阀。SPC可以满足基汽透平或燃气透平燃料操控阀所要求的操控精度、响应性和冗余性的要求

8237-1246 WOODWARD servo controller

The Model 8237-1246 is part of the Woodward ProTech-Gll series. It is an overspeed detection system that can be equipped for use with many types of turbines. If it senses excessive acceleration of water, steam and gas turbines, it can safely shut them off. In addition to acceleration detection, it also has MPU detection. Type 8237-1246 is also resistant to sulfur, H2S and S02 gases. It features a triple modular design for easy replacement during product operation - one part

The ProTech-Gll is an overspeed safety device designed to safely seal steam, gas and water turbines of all sizes when an overspeed or superacceleration event is sensed.

The WOODWARD Current Pressure Converter (CPC) is designed to operate steam valves, fuel and salt corresponding servomechanisms, and converts the 4-20mA control signal linearly and proportionally to the oil pressure output. The CPC can be used with many electronic control devices, such as WOODWARD MicroNet or 505 series controllers. It is suitable for pressure servo system or single effect power cylinder. CPC is also suitable for old machine renovation projects.

Woodward TG-13 and TG-17 are mechanical hydraulic differential governors used to control steam turbines, which do not need to operate in a synchronous (constant speed) manner. The TG-13 and TG-17 governor output shaft has a maximum rotating viewpoint of 40 ", and the recommended Angle travel from no load to full load is 213 of the full travel of the governor. WOODWARDTG-13E and TG-17E electro-hydraulic actuators are equipped with independent fuel sources, suitable for steam turbines requiring differential speed regulation, load distribution or other functions. Compatible with all WOODWARD electronic controls and accessories.

The WOODWARD Servo Bearing Controller (SPC) is a co-serving valve driver that accepts the DeviceNet or 4-20mA bearing command signal from the system controller and can precisely position the share or integral servo valve. SPC can meet the requirements of control accuracy, responsiveness and redundancy required by fuel control valves for base steam or gas turbines
