Woodward 工业控制产品线目录

The GECO™ Stoichiometric Model 100 (GECO S100) was designed as an inexpensive, state-of-the-art air/fuel ratio control for natural gas engines in the aftermarket. The GECO S100 is an easy-to-install, low maintenance, and expandable solution for natural gas engines. Woodward is the only manufacturer offering a system for the stationary engine market combining air/fuel ratio with adaptive catalyst control and oxygen sensor health monitoring. The GECO S100’s wide range of control authority quickly manages engine speed and load variations. (product spec 03553) 

The GECO™ S100 Lean Burn configuration is also available to further enhance emissions control. (product spec 03251)

The TecJet™ 50 Plus and TecJet 110 are electronic gas metering valves for single-point injection. They have integrated sensors and electronics, which provide the correct gas flow under all specified conditions. The microcomputer inside the TecJet valve converts the desired gas flow signal and gas parameter information into a valve position (which corresponds to the desired gas flow), depending on gas inlet pressure, gas temperature, and the pressure difference across the valve. (product spec 03317)

The 2301A Full Authority Speed Control sets the speed or load of a diesel engine, gas engine, steam turbine, or gas turbine according to the demand of a process or a computer control signal of 4–20 mA or 1–5 Vdc. The unit provides isochronous operation, with droop control available through an externally-wired potentiometer. The isochronous mode is used for constant speed of the controlled prime mover as long as it is able to provide power to satisfy the load. Droop control is provided when parallel-bus operation is required. (product spec 03201)

The 2301A Load Sharing and Speed Controls are designed for use in electric generator systems where multi-unit load sharing is desired. 2301A controls may be used with diesel, gas or gasoline engines, or steam or gas turbines. Controls are available for applications requiring droop and/or isochronous speed control; in forward- or reverse-acting models; for single or tandem actuator installations; with accelerating or decelerating ramps; and in several speed ranges. Automatic, adjustable start fuel limiting regulates the maximum fuel setting while the engine is starting. This helps decrease pollution and engine wear. Each 2301A control has a self-contained load sensor. Most models provide a 0–200 mA output signal; 0–20 mA output is available for special applications. The output signal is proportional to the fuel setting needed to attain the desired speed/load. Position feedback from the actuator is not required. (product spec 82390)
