WOODWARD 9907-164是一種基于505和505E微處理器的調(diào)速器控制單元的一部分。這種控制模塊專門(mén)設(shè)計(jì)用于操作汽輪機(jī)、渦輪發(fā)電機(jī)和渦輪膨脹機(jī)模塊。它能夠通過(guò)操作汽輪機(jī)的單一抽汽和/或進(jìn)汽來(lái)控制汽輪機(jī)。它利用汽輪機(jī)的分段執(zhí)行機(jī)構(gòu)，其中一個(gè)或兩個(gè)，來(lái)驅(qū)動(dòng)蒸汽入口閥。
9907-164裝置旨在通過(guò)操作汽輪機(jī)的單一抽汽和/或進(jìn)汽來(lái)控制汽輪機(jī)。它利用汽輪機(jī)的分段執(zhí)行機(jī)構(gòu)，其中一個(gè)或兩個(gè)，來(lái)驅(qū)動(dòng)蒸汽入口閥。與任何505調(diào)速器模塊一樣，該裝置能夠由現(xiàn)場(chǎng)操作員在現(xiàn)場(chǎng)進(jìn)行配置。菜單驅(qū)動(dòng)軟件由集成在設(shè)備正面的操作員控制面板控制和更改。該面板顯示兩行文本，每行24個(gè)字符。
9907-164配備了一系列離散和模擬輸入：16個(gè)觸點(diǎn)輸入（其中4個(gè)是專用的，12個(gè)是可編程的），然后是6個(gè)可編程的電流輸入，在4至20毫安。標(biāo)準(zhǔn)功能包括臨界速度避免、閥門(mén)限制器、自動(dòng)啟動(dòng)順序和停機(jī)先出指示器。

WOODWARD 9907-164 is a part of a governor control unit based on 505 and 505E microprocessors. This control module is specifically designed for operating steam turbines, turbo generators, and turbo expander modules. It can control the turbine by operating a single extraction and/or inlet of the turbine. It utilizes the segmented actuator of the steam turbine, one or two of which, to drive the steam inlet valve.
The 9907-164 device aims to control the turbine by operating a single extraction and/or inlet of the turbine. It utilizes the segmented actuator of the steam turbine, one or two of which, to drive the steam inlet valve. Like any 505 governor module, this device can be configured by on-site operators on site. The menu driven software is controlled and modified by an operator control panel integrated on the front of the device. This panel displays two lines of text, each containing 24 characters.
The 9907-164 is equipped with a series of discrete and analog inputs: 16 contact inputs (4 of which are dedicated and 12 are programmable), followed by 6 programmable current inputs ranging from 4 to 20 mA. Standard features include critical speed avoidance, valve limiter, automatic start sequence, and stop first out indicator.
