ABB IMHSS03 液压伺服模块

IMHSS03 液压伺服模块是 INFI 90® 系统中用于控制涡轮机转速的阀门位置控制模块。它将伺服阀或 I/H 转换器连接到 IMMFP01、IMMFP02 或 IMMFP03 多功能处理器模块。多功能处理器（MFP）模块通过向液压伺服（HSS）模块发送位置要求来控制蒸汽或燃气轮机节流阀的位置。HSS 模块驱动其输出以打开或关闭节流阀，以满足位置需求。多功能数码复合机模块使用IMFCS01频率计数器模块来测量涡轮机转速。频率计数器模块通过计算和定时来自涡轮轴上磁性拾音器的脉冲来测量涡轮速度。多功能数码复合机模块使用此计数来计算涡轮机转速，并根据设定点计算新需求。

The IMHSS03 hydraulic servo module is INFI 90 ® The valve position control module used to control the turbine speed in the system. It connects the servo valve or I/H converter to the IMMFP01, IMMFP02, or IMMFP03 multifunctional processor module. The Multifunctional Processor (MFP) module controls the position of steam or gas turbine throttle valves by sending position requirements to the Hydraulic Servo (HSS) module. The HSS module drives its output to open or close the throttle valve to meet position requirements. The multifunctional digital composite machine module uses the IMFCS01 frequency counter module to measure turbine speed. The frequency counter module measures turbine speed by calculating and timing pulses from the magnetic pickup on the turbine shaft. The multi-functional digital composite machine module uses this count to calculate the turbine speed and calculates new requirements based on the set point.
