Details
The SPHSS13 hydraulic servo module is a valve position control module.
It provides aninterface through which a HR Series controller can drive a servo valve or I/H converter toprovide manual or automatic control of a hydraulic actuator.
Typical areas of use for the SPHSS13 module are positioning the steam turbine throttle andcontrol valves, gas turbine fuel valves, inlet guide vanes and nozzle angle.
By regulating thecurrent to the servo valve, it can initiate a change in actuator position. The hydraulic actuatorcan then position, for example, a gas turbine fuel valve or a steam governor valve.
As thevalve opens or closes, it regulates fuel or steam flow to the turbine, thus controlling theturbine speed. A linear variable differential transformer (LVDT) provides actuator positionfeedback to the hydraulic servo module.
The SPHSS13 module interfaces to AC or DC LVDTsand can operate in Proportional-Only mode.The SPHSS13 is an intelligent I/O device with an onboard microprocessor, memoryand communication circuitry.
In most applications, the SPHSS13 will work in coordinationwith a speed detection module (SPTPS13) to form the turbine governor system.
The SPHSS13 module can also be used with non-modulating valves (open-close) to report thevalve position, without performing any actual valve control.
