WOODWARD 9907-149是一种数字调速器，专为工业规模的蒸汽涡轮机、小型涡轮发电机或公用事业涡轮膨胀机模块等设备而设计。它通过使用一对致动器来驱动进汽阀，从而使汽轮机运行。

这种数字调速器是调节直流电动机速度的设备，它上端和交流电源连接，下端和直流电动机连接。它将交流电转化成两路输出直流电源，一路输入给直流电机砺磁（定子），一路输入给直流电机电枢（转子）。通过控制电枢直流电压来调节直流电动机转速。

此外，WOODWARD 9907-149还配备了一个32位微处理器，以控制涡轮机。面板显示两行文本，每行24个字符。

使用WOODWARD 9907-149时，需要根据具体的工业应用场景和实际需求进行配置和控制程序的编写。在运行时，调速器将根据实际的控制需求进行自动调节和稳定控制，以确保汽轮机的正常运行和输出功率的精确控制。

WOODWARD 9907-149伍德沃德505数字调速器主要应用于蒸汽涡轮机、小型涡轮发电机或公用事业涡轮膨胀机模块等工业场合。它可以控制汽轮机的转速和输出功率，具有高精度、高稳定性、快速响应等特点，能够适应不同的汽轮机型号和运行环境。

在应用场景中，WOODWARD 9907-149数字调速器通过连接传感器和执行器，将汽轮机的转速信号转换为油压信号，再通过液压系统调节汽轮机的进气量或排气量，以实现汽轮机的稳定运行和输出功率的精确控制。同时，它还提供了多种控制功能，如热启动和冷启动的自动启动排序、温度输入选项、临界速度避免、外部报警输入、DI跳闸输入等，可以满足不同工业应用场景的控制需求。

WOODWARD 9907-149 is a digital governor designed for use in equipment such as industrial-scale steam turbines, small turbine generators, or utility turbine expander modules. It operates the steam turbine by using a pair of actuators to drive the intake valve.

The digital governor is a device that regulates the speed of the DC motor, its upper end is connected with the AC power supply, and the lower end is connected with the DC motor. It converts alternating current into two output DC power supplies, one input to the DC motor to sharpen the magnet (stator), one input to the DC motor armature (rotor). The speed of DC motor is adjusted by controlling the armature DC voltage.

In addition, the WOODWARD 9907-149 is equipped with a 32-bit microprocessor to control the turbine. The panel displays two lines of text, each of 24 characters.

When using WOODWARD 9907-149, it is necessary to write configuration and control programs according to specific industrial application scenarios and actual needs. During operation, the governor will automatically adjust and stabilize according to the actual control requirements to ensure the normal operation of the turbine and the accurate control of the output power.

The WOODWARD 505 digital governor is mainly used in industrial applications such as steam turbines, small turbine generators or utility turbine expansion modules. It can control the speed and output power of the steam turbine, has the characteristics of high precision, high stability, fast response, etc., and can adapt to different types of steam turbines and operating environments.

In the application scenario, the WOODWARD 9907-149 digital governor converts the speed signal of the turbine into the oil pressure signal by connecting the sensor and the actuator, and then adjusts the intake or exhaust volume of the turbine through the hydraulic system to achieve stable operation of the turbine and accurate control of the output power. At the same time, it also provides a variety of control functions, such as automatic start sequencing of hot start and cold start, temperature input options, critical speed avoidance, external alarm input, DI trip input, etc., can meet the control needs of different industrial application scenarios.
