Abstract

본 발명 원심펌프의 축추력 평형장치에 관한 것으로 특히 임펠러 후면 시라우드에 형성된 챔버내의 압력을 자동 조절하게 하므로써 축추력을 상쇄하여 궁극적으로 베어링의 신뢰성을 향상시켜 베어링의 수명연장 및 장치의 정비 요구를 최소화하는 것으로서 임펠러 후면링의 외경을 입구외경보다 크게 형성하고, 상기 임펠러 보스부의 후측면부와 대응하는 케이싱 커버의 사이에 축추력이 평형되도록 자동 조절되는 자동조절 수단을 구비한 것이다.The present invention relates to the axial thrust balancer of the centrifugal pump, in particular, by automatically adjusting the pressure in the chamber formed on the rear shroud of the impeller, thereby offsetting the axial thrust and ultimately improving the reliability of the bearing, thereby extending the service life of the bearing and maintaining the device. In order to minimize the outer diameter of the impeller rear ring larger than the outer diameter of the inlet, it is provided with an automatic adjustment means that is automatically adjusted so that the axial thrust is balanced between the rear surface portion of the impeller boss portion and the corresponding casing cover.
