伍德沃德WOODWARD电控液压放大器是一种导阀控制的线性伺服执行器。可与WOODWARD2301,500系列或NetCon控制器配套使用。
伍德沃德WOODWARD这个产自美国,其种类可分为:电磁阀,调速器,调节控制系统,电控液压放大器,执行器,电流压力转换器等。
伍德沃德具有130多年发动机控制器的设计和制造经验,广泛应用于航空、工业发动机、透平、及发电控制等。
液压放大器内的WOODWARDEG-3P执行器能将电控制信号转化为转动输出,再经液力放大,控制伺服位置输出。液压放大器适用于执行机构驱动力相对较大的汽轮机或大型发动机。
伍德沃德WOODWARDTG调速器是自含立油源、机械液压有差式调速器,适用于不需同步(等速)方式运行的小型蒸汽透平。
伍德沃德WOODWARDPG-PL调速器广泛应用于各种类型的柴油机、气体发动机和蒸汽透平的转速控制、驱动泵及压缩机等。
伍德沃德WOODWARDPGPL执行器应用于燃气发动机或蒸汽轮机上,可替换PGPL、PGL、PGD型调速器,而不需要改变原PG型驱动连杆机构。这就为电调改造提供了方便。
伍德沃德WOODWARD电流压力转换器(CPC)为控制蒸汽阀、燃料阀和/或相应的伺服机构而设计,它将4-20mA控制信号线性成比例地转换为油压输出。CPC可与许多电控装置匹配使用,如WOODWARDMicroNet或505系列控制器等。它适用于压力型伺服系统或单作用动力缸。CPC也适用于旧机改造项目。
伍德沃德WoodwardTG-13和TG-17是机械液压有差式调速器,用来控制汽轮机-这种不需同步(等速)方式运行的地方。TG-13和TG-17调速器输出轴的大旋转角度为40°。从空载到满载推荐的转角行程为调速器全行程的2/3。WOODWARDTG-13E和TG-17E电液执行器均自备立油源,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所有的电子控制器及附件兼容。
伍德沃德WOODWARD伺服位置控制器(SPC)是一个伺服阀驱动器,它接受来自系统控制器的DeviceNet或4-20mA位置指令信号,并能定位比例型或积分型伺服阀。SPC能够满足蒸汽透平或燃气透平燃料控制阀所要求的控制精度、响应性和冗余性的要求。
伍德沃德WoodwardProTech?203**速保护系统通过监测三路立的磁阻发讯器(MPU)来的信号,为蒸汽轮机、燃气轮机或其它原动机提供**速保护。特别是对于高转速(>10,000rpm)时机械**速保护装置已变得不可靠的情况下,可使用ProTech203替代。用于检测实际转速的传感器通常就是woodward磁阻式转速传感器(MPU)。
The WOODWARD Current-pressure Converter (CPC) is designed to control steam valves, fuel valves and/or corresponding servomotors by converting 4-20mA control **s linearly and proportionately to oil pressure output. CPC can be used with many electronic controls such as WOODWARDMicroNet or 505 series controllers. It is suitable for pressure servo system or single acting power cylinder. CPC is also applicable to old machine transformation projects.
WoodwardTG-13 and TG-17 are mechanical hydraulic differential governors used to control steam turbines - places that do not require synchronous (constant speed) operation. The maximum rotation Angle of tg-13 and TG-17 governor output shaft is 40°. The recommended turning stroke from no load to full load is 2/3 of the governor's full stroke. The WOODWARDTG-13E and TG-17E electro-hydraulic actuators are self-contained, self-contained oil sources for steam turbines requiring differential speed control, load distribution, or other functions, and are compatible with all WOODWARD electronic controllers and accessories.
WOODWARD Servo Position Controller (SPC) is a servo valve driver that accepts DeviceNet or 4-20mA position command **s from the system controller and can position proportional or integral servo valves. SPC is capable of meeting the control precision, responsiveness and redundancy requirements of steam or gas turbine fuel control valves.
WoodwardProTech? The 203 overspeed protection system provides overspeed protection for steam turbines, gas turbines, or other prime movers by monitoring **s from three independent reluctance transmitters (MPUs). In particular, ProTech203 can be used instead at high speeds (>10,000 RPM) where mechanical overspeed protection has become unreliable. The sensor used to detect the actual speed is usually the Woodward Reluctance speed sensor (MPU).
The Woodward 2301D-ST is microprocessor based with internal software designed specifically for single-valve steam turbine control. In order to facilitate the replacement of the controller, the arrangement of wiring ports of 2301D-ST is basically the same as that of 2301A controller. 2301D-ST controller can complete the core control of small steam turbine system. Its internal application software is field programmable to accommodate different configuration needs. Due to the enhanced function, the 2301D-ST has more input/output ports than the 2301A, and is equipped with a communication serial port, which greatly facilitates the communication between the controller and PLC or DCS control system.
The woodward2301D and 2301d-ec are based on microprocessor control and have the same functions as the 2301ALSSC: load distribution and speed control. The computer is connected to 2301D and 2301D-EC controllers through a 9-pin serial plug (RS232 port).
Woodward505 electronic governor is used to control the speed of turbine compressor. The Woodward 505 control system, designed and manufactured by Woodward, is microprocessor-based and can be used in steam turbines with either one or two actuators. The Woodward 505 control system has two modes of operation: programming mode and running mode. Programming mode is used to select the controller internal configuration and operation mode Settings; The operation mode is controlled according to the program set. Steam turbine electronic governor; Steam turbine electromechanical hydraulic converter; The output control ** of Wood Ward505 is converted into hydraulic ** through I/H converter to control the opening of steam turbine compressor's main steam door, so as to control the turbine compressor speed.
