Description

집단식(集團式)자동펌프용 안전장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
첨부도면은 유체동력학적 축받이가 달린 펌프를 도시한 것이다.

Claims (1)

  1. 회전하는 수직축과 연동하고, 펌프의 물통안에 배치되었으며, 그 바퀴테가 통상적으로 유체정력학적 축받이 위에 지지되어 있는 물갈퀴바퀴가포함된 가압수용집단식자동펌프를 위한 안전장치로서, 축(1)과 펌프몸통(8)의 안쪽벽(9)사이에 이러한 목적으로 마련된 공간안에서 축(1)과 축방향으로 놓인 통(10)에 의하여 구성되고, 통(10)의 내경이 축(1)의 직경보다 약간 더 크기 때문에, 유체정력학적 축받이(4)가 제대로 기능을 발휘하지 못할 경우에는 통이 내벽(9)과 더불어 일종ㅇ의 유체동력학적 축받이를 구성하며, 통의 내측표면중 일부(11)에 여러개의 실이 마련되어 있고, 이것들이 일종의 미궁을 구성하고;
    통(10)이 펌프몸통(8)의 안쪽벽(9)에 덮인 탄소피복에 의하여 구성되고;
    통(10)의 내경과 축(1)의 직경과의 차이가 축(1)의 정상적인 회전에 의하여 생기고 통(10)과 직경을 이루는 축의 진동폭보다 거의 3배정도 크게 구성함을 특징으로 하는 집단식(集團式)자동펌프용 안전장치.
