API611汽輪機機械-液壓調速器，螺桿轉速設定范圍為2400-4000 rpm，額定轉速在2時為4035 rpm，驅動軸逆時針旋轉，集成超速測試裝置（OTSD）適用于ATEX地區。調速器的23.7N·m（17.5 ft-lb）逆時針旋轉輸出端軸連接至汽輪機的調速閥，以控制汽輪機入口蒸汽流量。

特性和功能:

TG611-17壓鑄鋁機械-液壓降速調速器控制API611蒸汽渦輪機驅動泵、壓縮機或發電機，不需要同步（恒速）運行。調速器通過輸入驅動軸感應渦輪轉子速度來控制渦輪速度，將該速度與內部速度設定值進行比較，然后使用連接至渦輪調速閥的旋轉輸出端軸控制渦輪入口蒸汽流量。

這種獨立的調速器利用一個集成的驅動軸驅動的球頭組件來檢測渦輪機速度，并利用一個集成的驅動軸驅動的油泵來產生必要的輸出力，以移動/控制渦輪機的調速閥。TG611-17調速器包括一個特殊的超速測試裝置（OSTD），允許在安全的情況下從任何速度設置啟動受控和安全的汽輪機超速跳閘測試。

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.
