Product Description

http://tasker.us/source/woodward/tg/governor/04042_manual.pdf

The TG-13 and TG-17 Governors are suitable for use in European Zone 1,Group II environments per compliance with EN13463-5, Non-electrical equipment intended for use in potentially explosive atmospheres – Part 5; Protection by constructional safety ‘c’, with the following Special Conditions for Safe Use:
Special Conditions for Safe Use—Maximum Surface Temperature
The maximum surface temperature of the TG Governor is dependent upon three factors that are specific to the operating conditions of each individual application. These factors are as follows:
• Governor drive shaft speed
• Ambient temperature
• Hydraulic fluid selection (see Table 2-1)
The maximum surface temperature of the TG Governor must stay below the lowest ignition temperature of the surrounding explosive atmosphere and within allowable operating conditions for the hydraulic fluid selection. It is the user’s responsibility to maintain a safe surface and fluid temperature. If normal operating conditions cause the surface temperature of the TG to rise close to ignition temperatures or near the maximum recommended hydraulic fluid temperature, a heat exchanger must be installed. Refer to the sections on “Heat Exchanger Installation” and “When is a Heat Exchanger Necessary?” for location and sizing of the ports for connection of a heat exchanger.

Product parameter

The Woodward TG-13 and TG-17 are mechanical-hydraulic speed droop governors for controlling steam turbines—applications where isochronous (constant-speed) operation is not required.
The TG-13 and TG-17 governors have a full 40 degrees of maximum terminalshaft travel. Recommended travel from the no load to the full load position is 2/3 of full governor travel.
See Figure 1-1 for a graphic representation of maximum work capacity for the governors and related governor terminal shaft travel information.

Governor output is provided through a serrated terminal shaft extending from both sides of the case.
The internal pump for the governors is sized to operate over standard speed ranges:
• 1100 to 2400 rpm
• 2400 to 4000 rpm
• 4000 to 6000 rpm

Application field

The TG-13 governor operates with 1034 kPa (150 psi) internal oil pressure, and the TG-17 operates with 1379 kPa (200 psi) internal oil pressure.
Either governor is set to the speed range specified by the customer at time of order. The high-speed governor (4000 to 6000 rpm) may require a heat
exchanger in some applications (see end of Chapter 2, “When is a Heat Exchanger Necessary?”). Both governors are capable of controlling at lowerthan-specified speed range with some loss of output torque and performance.
The governor should not be run at a speed greater than the range specified because of heat rise and component wear issues.
The governors are available with either a cast-iron case or a die-cast aluminum case.
Speed droop is required for stable governor operation. Droop is factory set, but internally adjustable.
Two means of speed setting are available. Screw speed setting is standard. Lever speed setting is optional and provided by a serrated shaft assembly
extending from both sides of the cover.
