Measurments in turbine hydraulic

RECORDING AND ADJUSTMENTS OF TURBINE REGULATION IN TEST STATION AND ON SITE

EXAMINATIONS ON SITE

• RECORDING OF STATIC AND DYNAMIC CHARACTERISTICS OF STEAM TURBINE’S HYDRAULIC REGULATION SYSTEMS, IN ORDER TO ANALYSE WORKING ORDER OF REGULATION SYSTEM

• INFORMATION OBTAINED FROM SUCH ANALYSIS IS THEN USED FOR MAKING PROPER ADJUSTMENTS OR POSSIBLE IMPROVEMENTS IN REGULATING

EXAMINATIONS ON TTK TEST STATION RECORDING OD HYDRAULIC REGULATION COMPONENT’S CHARACTERISTICS BEFORE AND AFTER OVERHAUL:

  • Regulators/speed governors
  • Servomotors
  • E-H converters
  • possibility of ajustments and calibrations
  • posibilitty of carring our simulations and training

RECORDING OF LINER MOTION OF SERVOMOTOR IN RELATION TO IMPULSE OIL PRESSURE

TESTING AND ADJUSTMENTS OF SPEED GOVERNORS

IMPULSE OIL AND TACHOMETRIC OIL PRESSURES IN RELATION TO SPEED OF ROTATION

TESTING AND ADJUSTMENTS OF PISTON SERVOMOTOR

SIEMENS PISTON SERVOMOTOR DURING TESTING AND ADJUSTEMENT

RECORDING OF LINEAR MOTION OF SERVOMOTOR WITH RESPECT TO IMPULSE OIL PRESSURE

TESTING AND ADJUSTMENT OF VANE SERVOMOTOR

JUGOTURBINA VANE SERVOMOTOR DURING TESTING OF STATIC CHARACTERISTIC OPENING AND CLOSING OF REGULATING VALVES

RECORDING OF VALVE MOVEMENT(ANGLE OF SERVOMOTOR’S TURNING) WITH RESPECT TO IMPULSE OIL PRESSURE

PURPOSE OF RECORDING AND ADJUSTMENTS OF REGULATING SYSTEMS:

  • ensuring safe and reliable operation of steam trubine
  • recommendations for planned and emergency overhauls
  • evaluation of operation and requirements for replacement of components due to wear
  • possibility of installation of electronic components into the regulating system instead of
  • mechanical and / or hydraulic
  • control of correct functionality of new regulation and protection systems
