9907-164 技術規(guī)格

9907-164 裝置設計用于通過操作單個抽氣和/或進入渦輪機來控制蒸汽輪機。它利用渦輪機的分式執(zhí)行器（其中一個或兩個）來驅(qū)動蒸汽入口閥。

與任何 505 調(diào)速器模塊一樣，該裝置可由現(xiàn)場操作員在現(xiàn)場進行配置。菜單驅(qū)動的軟件由集成在設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 個字符。

9907-164 配備一系列離散和模擬輸入：16 個觸點輸入（其中 4 個專用，12 個可編程），然后是 6 個可編程電流輸入，電流為 4 至 20 mA。9907-164 功能中包含的標準功能包括臨界速度回避、氣門限制器、自動啟動順序和停機先出指示器。

9907-164

The 9907-164 unit is designed to control a steam turbine by operating a single extraction and/or entry turbine. It uses one or both of the turbine’s split actuators to drive the steam inlet valve.

As with any 505 governor module, the unit can be configured in the field by a field operator. Menu-driven software is controlled and changed by an operator control panel integrated on the front of the device. The panel displays two lines of text, each of 24 characters.

The 9907-164 is equipped with a range of discrete and analog inputs: 16 contact inputs (of which 4 are dedicated and 12 are programmable), followed by 6 programmable current inputs with currents from 4 to 20 mA. Standard features included in the 9907-164 feature include critical speed avoidance, valve limiter, automatic start sequence, and stop-first out indicators.
