A, use

ZGSA -d * S series intelligent integration of swinging cylinder adopts ABB, Siemens intelligent locator, is used in various automatic regulation control system consisting of various way, its control precision is high, and USES the liquid crystal display the man-machine dialogue interface, operation is very convenient. Especially for large power stations, boiler fuel, damper baffle opening adjustment.

Second, the classification of

ZGSA - D * S series intelligent integration of oscillating cylinder can be divided into intelligent integrated and intelligent remote system, integral type by ABB, Siemens intelligent integral type locator, cylinder parts and installation; Intelligent remote system refers to the actuators with ABB, Siemens intelligent positioner for opening adjustment of separate due to adopts the split type intelligent positioner (locator installation and control box), avoid locator is affected by the environment of high temperature, ensure the service life of the locator. And man-machine conversation interface during installation and debugging, debugging convenient, and the working performance is stable, control precision is very high, is currently the most advanced control of the opening of the secondary air door actuator.

Third, principle of work

The oscillating cylinder adopts compressed air as power source, form a complete set of electric/gas valve positioner for cylinder piston displacement and linearly

Input signal into a linear proportion, can adjust damper baffle opening.

Four, characteristics

1, export thrust large, schedule long, can multiplex control at the same time.

2, equipped with self-locking valve and valve position transmitter, air locking and signal feedback functions respectively.
