ACTUATOR APPARATUS AND A METHOD FOR INTEGRATING THIS ACTUATOR INTO TURBOMACHINERY

摘要

Apparatus and method for integrating an actuator into turbo-machinery and operating the actuator based on process fluid associated with the turbo-machinery. The integrated actuator mechanism includes an actuator casing; a balance drum, with labyrinth seals, and recovery spring, configured to apply force to the balance drum, in the actuator casing; an actuation bar connected to the balance drum and configured to move linearly in the direction of the balance drum; and a connection mechanism connecting a diverted portion of turbo-machinery process fluid to the actuator casing for applying force, in an opposite direction of the spring force, to the balance drum. The labyrinth seals allow the diverted turbo-machinery process fluid to bleed through and return to the turbo-machinery.

1. An actuator apparatus, comprising:
an actuator casing comprising:
a balance drum fitted to an inside surface of the actuator casing;a first connection on the actuator casing configured to allow a fluid to enter the actuator casing and exert a first force on the balance drum;a recovery spring configured to exert a second force on a first side of the balance drum; anda second connection on the actuator casing configured to allow the fluid to exit the actuator casing; an actuation bar connected to the balance drum; and a regulation valve in a line associated with the first connection and controlling the fluid flow to the first connection.
