Abstract

본 발명은 원심력을 제거한 배임펌프에 관한 것이다.The present invention relates to a pump that removes the centrifugal force.

종래의 배인펌프는 회전언심력에 의하여 배인이 케이싱의 내주면에 과도하게 밀착화전되어 심한 마찰저항으로 펌프의 부하가 크게되는 문제점이 있고 포터에 형성된 배인 삽입홈의 유극으로 유체가 압력을 받아 역유입되어 펌프의 성능저하와 압력손실이큰 문제점이 있었다.Conventional vane pump has a problem that the vane is excessively adhered to the inner circumferential surface of the casing due to the rotation core force, so that the load of the pump is increased due to severe frictional resistance. As a result, the performance degradation and pressure loss of the pump were large.

본 발명은 종래의 이러한 문제점을 시정할 목적으로 배인펌프의 케이싱(1)내부공간에 펌프실의 공간용적을 변화시키는 로터(2)를 편심회전축(3)으로 측판(1′)에 형성된 지축(3′)을 중심으로 회전할 수있게 설치된 것에 있어서, 로터의 회전축와 함께 회전되는 배인축(4)을 이중으로 설치하여 로터(2)에 형성된 배인삽입홈(5)으로 관통된 배인(6)의 내부부를 배인축(4)에 유착하여 설정된 원호궤도로 회전되게 하여 배인의 회전마찰 저항을 감소시키고 배인삽입홈(5)의 내단부에 3각형단면으로된 실링홈(5′)을 형성하여 원심력에 의하여 배인홈의 유글을 밀폐하는 실링 라운드 바아(7)를 실링홈(5′)에 삽입구동하여 배입삽입홈의 유극으로 압축공기나 유체의 역유입을 방지하여 밴펌프의 압력손실을 방지하고 펌프의 성능을 향상시키어 각종 산업용도에 사용할수 있게 한 것이다.The present invention provides a rotor shaft (3) formed on the side plate (1 ') with an eccentric rotation shaft (3) of a rotor (2) for changing the volume of the pump chamber in the inner space of the casing (1) of the vane pump. ′), The inside of the vane 6 penetrated by the vane inserting groove 5 formed in the rotor 2 by providing a double vane shaft 4 which is rotated together with the rotational axis of the rotor. The part is attached to the vane shaft 4 to be rotated in a set arc orbit to reduce the rotational frictional resistance of the vane and to form a sealing groove 5 'having a triangular cross-section at the inner end of the vane inserting groove 5 to provide centrifugal force. By inserting and driving the sealing round bar (7) sealing the ugle of the vane groove into the sealing groove (5 ') to prevent the back flow of compressed air or fluid into the gap of the insertion insertion groove to prevent the pressure loss of the van pump and pump Performance of various industrial applications It will be able.

Claims

The rotor (2) for changing the space volume of the pump chamber in the space of the casing (1) of the pump pump is known to be installed to rotate about the support shaft (3 ') of the shaft (1') to the eccentric rotation shaft (3). Thus, radially or slightly tilted radially penetrates the vane shaft (4) installed at the concentric position of the casing rotated together with the rotational axis of the rotor and the vane insertion groove (5) of the rotor circumference so as to rotate with a predetermined arc orbit A plurality of vanes 6 adhered to the vane shaft 4, a sealing groove 5 'formed in a triangular cross section at an inner end of each vane insertion groove 5, and a centrifugal force inserted into the sealing groove 5'. The vane pump is removed centrifugal force, characterized in that consisting of a sealing round bar (7) for maintaining the clearance of the vane insertion groove.
