TG-17 (4000 CCW)

4035 DROOP, CCW, SS, OSTD, ATEX

A 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 & FUNCTIONALITY

The TG-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.

Replaced by:  8516-187 with Overspeed Test Device (OTSD), or 9904-803 without OSTD

Applications:

Where isochronous (constant-speed) operation is not required, the TG-17 drives steam turbines in:
