  • The mechanism of power transmission from motor torque to stem thrust and the operation characteristic of each stroke position are analyzed using the diagnostic signal, and effects of differential pressure on the performance of motor operated flexible wedge gate valve are investigated. Test facility consists of 76 mm motor operated valve(flexible wedge type), pump and pipe system. Static and dynamic test are performed separately, and two differential pressure conditions are applied in the dynamic test. To evaluate the performance of valve, test signals for the torque, thrust, current, voltage and stroke length are acquired by using UDS which is diagnosis device for motor operated valve, and each diagnostic signal is analyzed and compared. The characteristic of valve performance factors such as stem factor, rate of loading, valve factor, are evaluated, and these factors are found to be severely influenced by the fluid differential pressure.

  • The new MOV(motor-operated valve) diagnostic system MOVIDS(MOV intelligent diagnostic system) was developed. Its remote diagnostic methods with high accuracy have improved the applicability. This enables the diagnostic tests and the evaluations of many MOVs not only at the valves but also in remote places like MCCs(motor control centers). The remote diagnostic ability of the new system reduces the cost and the man power for diagnosing MOVs and eliminates the danger of the toxic or radioactive environments to which workers might be exposed.

  • 추력기 시스템에 적용되는 밸브 구동장치용 제어기를 개발하였다. 추력기 시스템은 총 4개의 구동장치로 구성되어 있으며, 구동장치는 BLDC 모터를 적용하였다. 제어기는 구동장치 운용 조건과 제어 요건을 고려하여 설계 및 제작 되었다. 제어기 구성은 전원부, 제어부, 증폭부의 3부분으로 구성된다. 제어부의 Micro-controller는 TI사(社)의 TMS320F28335를 사용하여 Digital PID 제어 및 CAN 통신을 구현 하였다. 증폭부는 IGBT를 사용하여 3상 BLDC 모터의 구동을 수행 하였다.
