美国伍德沃德(WOODWARD)全系列产品,包括蒸汽轮机控制系统(505/505E/CPC-II等),柴油机调速器(UG系列),发电管理系统(Easygen控制器,SPM同步器等),燃气发电机控制系统(EGS02/EGS-TRIM系统),车用燃气控制系统(OH2.0)等产品的销售和配套,以及技术服务。
Also in the 1930s, Woodward developed a variable-pitch aircraft propeller governor. When the U.S. military's first turbo-powered aircraft flew successfully, its GE engine had a Woodward controller. Beginning in the 1950s, Woodward began designing electronic controls, first analog units, then digital units.
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.
In September 2017, Woodward had revenue of $2.1 billion, operating income of $280.18 million, net income of $200.51 million, total assets of $2.76 billion, total equity of $1.37 billion, and 6,900 employees.
The WOODWARD ELECTRONIC hydraulic Amplifier is a pilot valve controlled linear servo actuator. Available with WOODWARD2301, 500 series or NetCon controllers.
The WOODWARD brand is made in the United States. It can be divided into solenoid valves, governors, regulation control systems, electronic hydraulic amplifiers, actuators, current pressure converters, etc.
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).
