Description

철 함유 유체를 가진 다단계 밀봉장치.Multistage sealer with iron-containing fluid.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 "종래 기술"이라는 제하의 절에서 기술된 종래의 구조를 도시한다.Figure 1 shows the conventional structure described in the section under "Prior Art".

제2도는 특허청구 범위 제1항에 따라서, 하우징(6)내에 압입되는, 자기 입자로 충진된 플라스틱의 폐쇄블록으로 구성된 밀봉 소자를 도시한다. 이 실시예에서, 밀봉 소자는 밀봉 계단을 갖지 않는다. 이것들은 자화성 재료로 구성된 축의 표면상에 공급된다. 방향 표시 화살표가 주어지 플럭스(1)의 선은, 밀봉소자(2), 밀봉 계단 틈새(3)내의 철함유 유체, 한쪽의 밀봉계단(4), 축(5), 밀봉계단(4), 밀봉 계단틈새(3)내의 철함유 유체, 다른쪽의 밀봉 소자(2)를 통하여 완성되는 자기 플럭스를 도시한다.2 shows a sealing element consisting of a closed block of plastic filled with magnetic particles, which is pressed into the housing 6 according to claim 1. In this embodiment, the sealing element does not have a sealing step. These are supplied on the surface of the shaft made of magnetizable material. Given a direction arrow, the lines of the flux 1 include the sealing element 2, the iron-containing fluid in the sealing step clearance 3, one sealing step 4, the shaft 5, the sealing step 4, The iron-containing fluid in the sealing step clearance 3 and the magnetic flux completed through the other sealing element 2 are shown.

제3도는 특허청구 범위 제1항에 따라서, 자기 입자로 충진된 플라스틱의 폐쇄블록으로 구성된 밀봉 소자를 도시한다. 이 실시예에서는, 밀봉 계단은 밀봉 소자의 내부직경상에 설비된다.3 shows a sealing element consisting of a closed block of plastic filled with magnetic particles, according to claim 1. In this embodiment, the sealing step is provided on the inner diameter of the sealing element.
