Abstract
제어 가능성 및 절단 발생을 향상시키기 위해, 그리고 제어 속도를 높이기 위해, 본 발명에 따라, 절단 헤드(5) 내 노즐(51) 쪽으로 향하는 유체의 공급 라인(4) 또는 고압 라인의 영역 내에 개폐 가능한 스톱 밸브(stop valve)(54), 소위 절단 밸브가 배치되어 있다.
Description
도 1은 절단 헤드 내에 본 발명에 따른 스톱 밸브를 구비한 유체 젯- 또는 워터 젯 절단 장치를 도시하고,
도 2는 절단 헤드 내에 본 발명에 따른 스톱 밸브를 구비하고, 감소한 압력의 자체 펌프 장치를 구비한 유체 젯- 또는 워터 젯 절단 장치를 도시한다.
Claims (6)
- 유체 젯- 또는 워터 젯 절단 장치(1)로서,
경우에 따라 적어도 서로 다른 2개의 압력에 의해 구동 가능한 유압 유닛(2), 밸브들(31, 32)을 구비한 고압 라인(4) 내부의 적어도 하나의 맥동 감쇠기(pulsation damper)(3) 및 노즐(51) 및 연마 재료(53)용 혼합 장치(52)를 구비한 절단 헤드(5)를 포함하는 상기 유체 젯- 또는 워터 젯 절단 장치에 있어서,
