美国伍德沃德(WOODWARD)CPC,8901-457电液转换器
美国伍德沃德汽轮机电液转换器Woodward CPC (8901-457),它将4-20mA控制信号线性成比例地转换为油压输出。Woodward CPC可与许多电控装置匹配使用,如Woodward505e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。
WOODWARD CPC, 8901-457 electro-hydraulic converter
Woodward CPC (8901-457), a 4-20mA control ** is linearly proportional to the oil pressure output. The Woodward CPC is compatible with many electronic controls, such as the Woodward 505E controller. It is suitable for pressure servo system or single acting power cylinder. CPC is also applicable to old machine transformation projects.
Woodward & Company was founded in 1870 by Amos Woodward & Company as Woodward Governor & Company. At first, Governor Woodward controlled the water wheel (first patent no. 103813) and then switched to a hydraulic turbine. In the 1920s and 1930s, Woodward began designing diesel and other reciprocating engines, as well as controls for industrial turbines.
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).
Woodward 505/505E(9907-162,9907-164,9907-165,9907-167) digital controllers can be used to control industrial steam turbines, small grid turbine generators, or turbine expanders.
The 9905 series of woodward2301A controllers are designed for speed and load distribution control in generator sets driven by diesel engines, gasoline engines, steam turbines or gas engines. The 2310ALSSC controller can operate in harsh environments.
