| description | According to one embodiment of the present invention, a system for testing durability of a pedal valve comprises a pedal valve, a cylinder pressurizing the pedal valve, a pedal valve hydraulic part for supplying a valve operation oil to the pedal valve as the cylinder pressurizes the pedal valve forward or backward, a valve sensor part for sensing at least one of the pressure, speed, or flow rate of the valve operation oil discharged from the pedal valve, and a control part for determining or analyzing whether or not the pedal valve is in a normal operating state by using a sensing value of the valve sensor part. Reliability and durability of the pedal valve can accurately be tested as an actual operating condition or situation of a construction machine can be reproduced.
본 발명의 일 실시예에 따른 페달 밸브 내구성 시험 시스템은, 페달 밸브; 상기 페달 밸브를 가압하는 실린더; 상기 실린더가 상기 페달 밸브를 전진 가압 또는 후진 가압함에 따라 상기 페달 밸브에 밸브 작동유를 공급하는 페달 밸브 유압부; 상기 페달 밸브에서 배출되는 상기 밸브 작동유의 압력, 속도 또는 유량 중 적어도 하나를 센싱하는 밸브 센서부; 및 상기 밸브 센서부의 센싱값을 이용하여 상기 페달 밸브의 정상 작동 상태 여부를 판별하거나 분석하는 제어부;를 포함하여, 건설기계의 실제 운전 조건 또는 상황을 재현할 수 있기 때문에 페달 밸브의 신뢰성 내지 내구성을 정확하게 시험할 수 있다. |
