WOODWARD TGE Turbine Actuators

WOODWARD TGE Turbine Actuators

Product Overview and Features

Core function: Receive control signals from speed controllers (such as TG Turbine Governors), drive valves, throttle valves and other mechanisms through hydraulic or electric means, regulate the steam or fuel input of the turbine, and achieve speed control.

Working principle: The electrical signal is converted into mechanical displacement through an electro-hydraulic servo system, which drives the actuator to act with fast response speed and high control accuracy.

Model and specifications

1. Basic model classification

Divided by rotational speed:

TGE13 series: suitable for 2400 rpm, 4000 rpm, 6000 rpm turbine systems.

Example of Part Number:

TGE13, 2400 rpm (part number: 9904-110).

TGE13, 4000 rpm (part number: 9904-111).

TGE13, 6000 rpm (part number: 9904-112).

TGE17 series: higher torque design, compatible with the same speed range, part number such as:

TGE17, 2400 rpm (part number: 9904-113).

TGE17, 4000 rpm (part number: 9904-114).

TGE17, 6000 rpm (part number: 9904-115).

Core parameters:

Output torque: Depending on the model, adapt to the turbine power requirements to ensure the driving force for valve adjustment.

Response time: Quickly respond to governor signals and reduce speed fluctuations.

Structure and working characteristics

Electro hydraulic design:

Built in hydraulic cylinder and servo valve, control the flow of hydraulic oil through electrical signals, drive the piston rod to move linearly, and drive mechanical loads.

compatibility:

Seamless integration with turbine governors such as TG13 and TG17, forming a closed-loop control chain of "governor actuator".

Protection and Certification:

Some models support ATEX certification and are suitable for Zone 2 hazardous areas. The structural design is vibration resistant and oil resistant.

Application scenarios

Industrial turbine control:

Adjust the steam valve and fuel valve of steam turbine and gas turbine to maintain stable speed.

Power drive system:

When driving equipment such as compressors, pumps, generators, etc., adjust the turbine output according to load changes.

In the field of energy and chemical engineering:

Ensure reliable operation of turbine equipment in power plants, oil pipelines, and refining facilities under different operating conditions.

Accessories and Maintenance

Sealing kit: used for replacing cylinder seals during maintenance to ensure that the hydraulic system is leak free (refer to Woodward spare parts catalog).

Hydraulic oil: It is recommended to use hydraulic oil that meets the specifications to maintain the performance of the actuator.

Monitoring and debugging:

Real time monitoring of actuator position and hydraulic status through Woodward MicroNet system or Flex500 platform, supporting remote debugging.

Advantages and Characteristics

High precision control: The electro-hydraulic servo system achieves millimeter level displacement control, adapting to precision adjustment requirements.

High reliability: Durable mechanical structure, redundant hydraulic system design, reducing the risk of downtime due to malfunctions.

Flexible adaptation: Multiple speed specifications cover different turbine models and support customized configuration.
