產(chǎn)品詳情

WOODWARD 9907-149是一種數(shù)字調(diào)速器，專為工業(yè)規(guī)模的蒸汽渦輪機(jī)、小型渦輪發(fā)電機(jī)或公用事業(yè)渦輪膨脹機(jī)模塊等設(shè)備而設(shè)計(jì)。它通過使用一對致動(dòng)器來驅(qū)動(dòng)進(jìn)汽閥，從而使汽輪機(jī)運(yùn)行。

這種數(shù)字調(diào)速器是調(diào)節(jié)直流電動(dòng)機(jī)速度的設(shè)備，它上端和交流電源連接，下端和直流電動(dòng)機(jī)連接。它將交流電轉(zhuǎn)化成兩路輸出直流電源，一路輸入給直流電機(jī)礪磁（定子），一路輸入給直流電機(jī)電樞（轉(zhuǎn)子）。通過控制電樞直流電壓來調(diào)節(jié)直流電動(dòng)機(jī)轉(zhuǎn)速。

此外，WOODWARD 9907-149還配備了一個(gè)32位微處理器，以控制渦輪機(jī)。面板顯示兩行文本，每行24個(gè)字符。

使用WOODWARD 9907-149時(shí)，需要根據(jù)具體的工業(yè)應(yīng)用場景和實(shí)際需求進(jìn)行配置和控制程序的編寫。在運(yùn)行時(shí)，調(diào)速器將根據(jù)實(shí)際的控制需求進(jìn)行自動(dòng)調(diào)節(jié)和穩(wěn)定控制，以確保汽輪機(jī)的正常運(yùn)行和輸出功率的精確控制。

WOODWARD 9907-149伍德沃德505數(shù)字調(diào)速器主要應(yīng)用于蒸汽渦輪機(jī)、小型渦輪發(fā)電機(jī)或公用事業(yè)渦輪膨脹機(jī)模塊等工業(yè)場合。它可以控制汽輪機(jī)的轉(zhuǎn)速和輸出功率，具有高精度、高穩(wěn)定性、快速響應(yīng)等特點(diǎn)，能夠適應(yīng)不同的汽輪機(jī)型號(hào)和運(yùn)行環(huán)境。

在應(yīng)用場景中，WOODWARD 9907-149數(shù)字調(diào)速器通過連接傳感器和執(zhí)行器，將汽輪機(jī)的轉(zhuǎn)速信號(hào)轉(zhuǎn)換為油壓信號(hào)，再通過液壓系統(tǒng)調(diào)節(jié)汽輪機(jī)的進(jìn)氣量或排氣量，以實(shí)現(xiàn)汽輪機(jī)的穩(wěn)定運(yùn)行和輸出功率的精確控制。同時(shí)，它還提供了多種控制功能，如熱啟動(dòng)和冷啟動(dòng)的自動(dòng)啟動(dòng)排序、溫度輸入選項(xiàng)、臨界速度避免、外部報(bào)警輸入、DI跳閘輸入等，可以滿足不同工業(yè)應(yīng)用場景的控制需求。

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.
