Abstract

레이디얼 플런저 펌프는 하우징과, 펌프 하우징 내에 회전 가능하게 지지된 구동 샤프트와, 편심 캠의 축이 기하학적 중심으로부터 벗어나도록 구동 샤프트에 고정 연결된 원통형 편심 캠과, 하우징 내에 형성된 복수개의 반경 방향 원통형 보어와, 왕복 운동하도록 각각이 관련 원통형 보어 내에 수납되고 편심 캠의 외측 외주를 향해 스프링 편의된 복수개의 반경 방향 플런저를 포함한다. 또한, 편심 캠에 대하여 상대적으로 회전할 수 있도록 편심 캠의 외측 외주에 끼워진 보조 링이 마련된다. 구동 샤프트를 둘러싸면서 하우징 내의 공간을 작동 유체 챔버와 윤활제 챔버로 분할하도록 보조 링과 하우징 사이에 가요성 격벽 부재가 마련된다. 윤활제 챔버는 구동 샤프트 저널의 적당한 윤활과, 구동 샤프트 둘레에 배치된 오일 시일의 양호한 밀봉을 위한 윤활제로 충전된다.The radial plunger pump includes a housing, a drive shaft rotatably supported in the pump housing, a cylindrical eccentric cam fixedly connected to the drive shaft so that the axis of the eccentric cam is out of the geometric center, and a plurality of radial cylindrical bores formed in the housing; And a plurality of radial plungers, each of which is housed in an associated cylindrical bore for reciprocating movement and spring biased toward the outer circumference of the eccentric cam. Further, an auxiliary ring fitted to the outer circumference of the eccentric cam is provided so as to be able to rotate relative to the eccentric cam. A flexible partition member is provided between the auxiliary ring and the housing to divide the space within the housing into a working fluid chamber and a lubricant chamber while surrounding the drive shaft. The lubricant chamber is filled with lubricant for proper lubrication of the drive shaft journal and good sealing of the oil seal disposed around the drive shaft.
