API611汽轮机机械-液压调速器，螺杆转速设定范围为2400-4000 rpm，额定转速在2时为4035 rpm，驱动轴逆时针旋转，集成超速测试装置（OTSD）适用于ATEX地区。调速器的23.7N·m（17.5 ft-lb）逆时针旋转输出端轴连接至汽轮机的调速阀，以控制汽轮机入口蒸汽流量。

特性和功能:

TG611-17压铸铝机械-液压降速调速器控制API611蒸汽涡轮机驱动泵、压缩机或发电机，不需要同步（恒速）运行。调速器通过输入驱动轴感应涡轮转子速度来控制涡轮速度，将该速度与内部速度设定值进行比较，然后使用连接至涡轮调速阀的旋转输出端轴控制涡轮入口蒸汽流量。

这种独立的调速器利用一个集成的驱动轴驱动的球头组件来检测涡轮机速度，并利用一个集成的驱动轴驱动的油泵来产生必要的输出力，以移动/控制涡轮机的调速阀。TG611-17调速器包括一个特殊的超速测试装置（OSTD），允许在安全的情况下从任何速度设置启动受控和安全的汽轮机超速跳闸测试。

An API611 steam turbine mechanical-hydraulic governor with screw speed set range of 2400-4000 rpm, rated speed-droop at 4035 rpm at 2°, with a counterclockwise drive shaft rotation, and integrated overspeed test device (OTSD) for ATEX locations. The governor’s 23.7 N m (17.5 ft-lb) counterclockwise rotary output terminal shaft connects to the turbine’s governor valve to control turbine inlet steam flow.

Features & Functions:

The TG611-17 die-cast aluminum mechanical-hydraulic speed droop governor controls API611 steam turbines driving pumps, compressors, or generators where isochronous (constant-speed) operations is not required. The governor controls turbine speed by sensing turbine rotor speed via the input drive shaft, comparing this speed to an internal speed set point, then using a rotary output terminal shaft connected to the turbine’s governor valve control turbine inlet steam flow.

This self-contained governor utilizes an integrated driveshaft-driven ball head assembly to sense turbine speed, and an integrated driveshaft-driven oil pump to create the necessary output force to move/control the turbine’s governor valve. The TG611-17 governor includes a special Overspeed Test Device (OSTD), allowing controlled and safe turbine overspeed trip testing initiated from any speed setting in a safe matter.
