Description

회전통체를 갖는 베인형 펌프Vane type pump with rotating cylinder
본 발명은 유체기계에 관한 것으로서, 보다 구체적으로는 로터리식 중 베인형 펌프의 원리를 이용하되 베인의 마모를 최소화함으로써 내구성 향상에 크게 기여한 것을 특징으로 하는 회전통체를 갖는 펌프에 관한 것이다.The present invention relates to a fluid machine, and more particularly, to a pump having a rotating cylinder, which uses the principle of a rotary vane type pump but contributes to the improvement of durability by minimizing the wear of the vane.
펌프는 유체를 이송시키기 위한 유체기계의 일종이며, 대표적인 것이 진공펌프, 압축기가 있다. 본 발명은 진공펌프를 예시하고 있으며, 이하 진공펌프를 대표하여 설명한다. A pump is a kind of fluid machine for conveying fluids, and a typical pump is a vacuum pump and a compressor. The present invention exemplifies a vacuum pump, and will be described below on behalf of a vacuum pump.
종래의 진공펌프는 회전자, 즉 로터의 모양에 따라 베인(vane)형, 루츠(roots)형, 스크류형 등으로 구분될 수 있다. 루츠형과 스크류형 진공펌프는 외통과 로터가 일정한 간격으로 이격되어 있는 상태로 고속으로 회전하면서 진공을 형성시키는데 가공비가 비싸고 소음이 심하며 배출공기의 온도가 상승하여 진공펌프의 크기를 크게 제작하여야 하는 단점을 갖고 있다. Conventional vacuum pumps may be divided into vane type, root type, screw type, and the like according to the shape of the rotor, that is, the rotor. Roots type and screw type vacuum pump rotates at high speed while the outer cylinder and the rotor are spaced at regular intervals to form a vacuum. The processing cost is high, the noise is high, and the temperature of the exhaust air rises, which makes the size of the vacuum pump large. It has a disadvantage.
반면 베인형 진공펌프는 베인의 마모가 심하게 발생하여 자주 교체해주어야 하고 이물질이 끼일 경우 카본소재의 베인이 파손되는 문제가 있다. 이하 도 1을 참조하여 베인형 진공펌프의 구성을 간략히 설명하고 그 문제를 살펴본다. On the other hand, the vane type vacuum pump has a problem that the vanes of the carbon material are damaged when the vanes are badly worn and need to be replaced frequently. Hereinafter, the configuration of the vane type vacuum pump will be briefly described with reference to FIG. 1, and the problem thereof will be described.
베인형 진공펌프(100)는 하우징(101)의 내부에 로터(103)를 편심되게 설치하고, 이 로터(103)에 한 개 이상의 베인(105)을 설치하고 로터(103)의 회전에 따라 베인(105)을 회전시켜 내부공간(107)의 체적을 변화시킴으로써 가스와 같은 유체를 펌핑하는 장치이다.The vane-type vacuum pump 100 eccentrically installs the rotor 103 inside the housing 101, installs one or more vanes 105 in the rotor 103, and vanes according to the rotation of the rotor 103. A device for pumping a fluid such as a gas by rotating the 105 to change the volume of the internal space 107.
공기 등 유체의 흡입구(109)와 토출구(111)는 서로 대향된 위치에 마련된다. 복수 개의 베인(105)은 로터(103)의 반경 방향으로 돌출되거나 삽입될 수 있게끔 로터(103)에 마련된 슬롯에 끼워져 설치된다. 베인(105)은 판형상을 가지며 보통 고체윤활을 위하여 탄소를 소재로 하여 제작된다. The inlet port 109 and the outlet port 111 of the fluid such as air are provided at positions facing each other. The plurality of vanes 105 are installed in a slot provided in the rotor 103 so that the vanes 105 may protrude or be inserted in the radial direction of the rotor 103. The vanes 105 have a plate shape and are usually made of carbon for solid lubrication.
도시된 진공펌프(100)는 로터가 회전하면서 흡입구에서 유체를 빨아들여 토출구로 내보내는 구조로 되어 있다. 종래의 로터리식 진공펌프에 의하면 베인이 하우징 내면(101a)과 극심한 마찰을 겪게 된다. 고체윤활이나 기타 윤활수단이 사용되기는 하지만 마찰에 의한 베인(105)의 마모는 피할 수가 없다. 베인(105)의 마모는 진공펌프의 내구성과 직결되며 따라서 종래의 로터리식 베인형 진공펌프는 내구성이 낮은 문제를 가지고 있다. The illustrated vacuum pump 100 has a structure in which the rotor sucks fluid from the suction port and discharges the fluid to the discharge port while the rotor rotates. According to the conventional rotary vacuum pump, the vane is subjected to extreme friction with the housing inner surface (101a). Although solid lubrication or other lubrication means are used, wear of the vanes 105 by friction is inevitable. The wear of the vane 105 is directly related to the durability of the vacuum pump, and therefore, the conventional rotary vane type vacuum pump has a problem of low durability.

이하, 첨부된 도 2 내지 도 5를 동시에 참조하여 본 발명의 구체적인 내용을 상세하게 설명한다. Hereinafter, with reference to the accompanying Figures 2 to 5 will be described in detail the specific content of the present invention.
원통 형상의 하우징(1)이 베이스(3)에 직접 또는 간접적으로 고정 설치된다. 하우징(1) 양측에는 측판(5)이 볼트로써 결합된다. 도시된 바에 의하면 하우징(1)은 측판을 매개로 하여 베이스(3)에 고정 설치되고 있다. The cylindrical housing 1 is fixed to the base 3 directly or indirectly. Side plates 5 are coupled to both sides of the housing 1 by bolts. As shown, the housing 1 is fixed to the base 3 via a side plate.
흡입구(7)와 토출구(9)는 측판(5) 중 어느 하나에 마련되며 도시된 바에 의하면 원형으로 되어 있다. 구동모터(11)가 하우징 옆에 있도록 베이스(3) 위에 고정 설치된다. 구동축(13)과 구동모터(11)는 벨트(17)와 같은 전동수단에 의해 연결되거나 구동모터(11)와 직접 연결 될 수 있다. 이러한 도 2에 도시된 형태는 예시일 뿐이며 다양한 디자인으로 제공될 수 있음은 당연하다. 중요한 것은 내부 구성 및 동작원리일 것이므로 이하에서는 내부구성에 대하여 도 3 내지 도 5를 참조하여 설명한다.The suction port 7 and the discharge port 9 are provided in any one of the side plates 5 and are circular as shown.

For example, it should be as short as 0.1 ~ 0.2mm because only minimal difference can be prevented. Of course, the diameter of the rotating cylinder 19 is smaller than the housing 1 is to be installed in the housing. The bearing has a ring shape and may be installed at both ends of the rotating cylinder 19, respectively. Bearing 21 may be of any type and may be replaced by lubrication means.
원기둥 형태의 로터(23)가 회전통체(19) 내부에 회전 가능하게 설치된다. 로터는 회전통체의 중심축으로부터 편심된 상태에서 회전한다. 로터를 회전시키기 위한 구동부는 전술한 바와 같이 구동모터, 벨트 등을 포함한다. The cylindrical rotor 23 is rotatably installed inside the rotating cylinder 19. The rotor rotates while being eccentric from the central axis of the rotating cylinder. The drive unit for rotating the rotor includes a drive motor, a belt and the like as described above.
본 발명의 실시예에 의하면 구동축의 회전중심축(X')이 하우징 및 회전통체(19)의 중심축(X)에 대하여 이심된 위치에 설치된다. 도시된 바에 의하면 구동축(13)의 회전중심축(X')이 하우징(1) 및 회전통체(19)의 중심축(X)에 대하여 상방향으로 이심되어 있으며, 이심거리(M)는 상황에 따라 다르게 결정될 수 있겠다. 예를 들어 이심거리는 10 ~ 100mm가 될 수 있다. According to the embodiment of the present invention, the center of rotation X 'of the drive shaft is installed at a position eccentric with respect to the center axis X of the housing and the rotating cylinder 19. It is shown that the central axis of rotation X 'of the drive shaft 13 is eccentric with respect to the central axis X of the housing 1 and the rotating cylinder 19, and the eccentric distance M is It can be decided differently. For example, the eccentricity can be 10 to 100 mm.
베인슬롯(25)이 로터(23)의 원주방향을 따라 2곳 이상에 반경방향으로 마련된다. 판형상의 베인(27)이 베인슬롯(25)으로부터 슬라이딩되면서 돌출 또는 그 내부로 삽입 가능하게끔 베인슬롯(25)에 끼워진다. 스프링(미도시됨)이 베인슬롯(25)의 바닥(25a)과 베인(27) 사이에 개입되어 베인(27)으로 하여금 탄성적으로 돌출되는 힘을 받도록 할 수 있다. 스프링은 코일스프링일 수도 있고 판스프링일 수도 있다. 스프링은 선택적 사항이면 단순히 원심력에 의해서만 베인(27)이 돌출되도록 할 수도 있다. Vane slots 25 are provided in two or more places along the circumferential direction of the rotor 23 in the radial direction. The plate-shaped vanes 27 are fitted into the vane slots 25 so as to be protruded or inserted into the vanes while sliding from the vane slots 25. A spring (not shown) may be interposed between the bottom 25a of the vaneslot 25 and the vanes 27 to cause the vanes 27 to receive the elastically projecting force. The spring may be a coil spring or a leaf spring. The spring may optionally cause the vanes 27 to protrude only by centrifugal force.
회전통체구동부는 베인(27)과 회전통체(19)가 함께 회전하도록 한다. The rotary cylinder driving unit allows the vane 27 and the rotary cylinder 19 to rotate together.
본 발명의 실시예에 의하면, 회전통체구동부는 회전통체(19)와 베인(27)이 서로 구속되어 함께 회전하도록 하는 결속수단이 될 수 있다. 이에 의하면 회전통체(19)는 베인(27)에 전달되는 회전력에 의해 회전되는 것일 수 있다. 그리고 회전통체구동부는 상기 베인(27)과 회전통체(9) 사이에서 회전방향으로의 상대적 유동(즉 어느 정도의 슬립 현상)을 허용하여야 한다. According to an embodiment of the present invention, the rotary cylinder driving unit may be a binding means for the rotary cylinder 19 and the vane 27 to be constrained and rotate together. According to this, the rotating cylinder 19 may be rotated by the rotational force transmitted to the vane 27. And the rotating cylinder drive should allow relative flow in the direction of rotation between the vane 27 and the rotating cylinder (ie, some degree of slip phenomenon).
그리고 본 실시예에 의하면 결속수단은 회전통체(19) 내부에 돌출되어 베인(27)의 측면에 지지되도록 설치되는 하나 이상의 걸쇠(29)일 수 있다. 도시된 바와 같이 걸쇠(29)는 대칭을 이루도록 2개가 설치될 수 있다. 걸쇠(29)는 돌기 형태도 될 수 있지만 바(bar) 형태가 적합할 것이다. 경우에 따라 걸쇠(29)를 대체하여 베인(27)의 끝이 끼워질 수 있는 걸홈이 설치될 수도 있다. 기타 다양한 방식으로 베인(27)과 회전통체(19)를 결속시킬 수 있을 것이다. And according to this embodiment, the binding means may be one or more clasps 29 protruding inside the rotating cylinder 19 to be supported on the side of the vane 27. As shown in the figure, two clasps 29 may be installed to achieve symmetry. Clasp 29 may also be a protrusion, but a bar shape would be suitable. In some cases, the latch groove 29 may be installed to replace the end of the vane 27. The vanes 27 and the rotating cylinder 19 may be coupled in various other ways.
결속수단은 베인(27)으로 하여금 베인슬롯(25) 내에서의 반경방향(W)을 따른 슬라이딩 운동을 가능케 하는 것을 조건으로 제공된다. 이에 의하면 베인(27)과 회전통체(19)의 축중심으로 한 상대적 위치는 고정되게 된다. 다만 반경방향(W)으로의 상대적 위치만이 고속으로 변환되게 되는 것이다. The binding means are provided provided that the vanes 27 enable sliding movement along the radial direction W in the vaneslot 25. According to this, the relative position of the vane 27 and the rotating cylinder 19 at the center of the shaft is fixed. Only the relative position in the radial direction (W) is to be converted at high speed.
이에 의하여 회전통체(19), 로터(23) 및 베인(27)에 의해 이루어지는 밀폐된 단위공간(S1~S4)의 체적이 연속하여 변화되는 것이며, 이에 의해 진공 및 압축작용이 반복적으로 이루어지며 여느 진공펌프와 같이 흡입과 토출이 반복적으로 이루어지게 되는 것이다. As a result, the volume of the closed unit spaces S1 to S4 formed by the rotating cylinder 19, the rotor 23, and the vanes 27 is continuously changed, whereby vacuum and compression are repeatedly performed. Like a vacuum pump, suction and discharge are repeated.
위와 같은 구성에 의하면 베인(27)이 회전통체(19)를 회전시키는 힘을 전달하므로 베인(27)에 편심하중이 가해지게 된다. 지속적이며 강한 편심하중은 베인(27)에 대하여 좋지 않은 영향을 줄 수 있다. According to the configuration as described above, because the vane 27 transmits the force to rotate the rotary cylinder 19, the eccentric load is applied to the vane 27. Continuous and strong eccentric loads can adversely affect the vanes 27.
이러한 문제에 대하여 회전통체구동부는 기어 또는 벨트와 같은 전동기구를 통해 구동부에 연결됨으로써 로터(23)와 함께 회전 구동되도록 할 수도 있다. 하나의 구동모터(11)로써 회전통체(19)와 로터(23)를 동시에 구동시키도록 하는 것이다. 같은 방향으로 회전하기만 하면 완전히 동일한 회전속도로 회전시킬 필요도 없다. 상대적 회전속도를 줄임으로써 마찰을 감소시킬 수만 있다면 본 발명의 목적이 어느 정도 달성되는 것이기 때문이다. With respect to this problem, the rotary cylinder driving unit may be driven to rotate together with the rotor 23 by being connected to the driving unit through an electric mechanism such as a gear or a belt. One drive motor 11 to drive the rotary cylinder 19 and the rotor 23 at the same time. You do not have to rotate at exactly the same speed as long as you rotate in the same direction. This is because the object of the present invention is achieved to some extent as long as the friction can be reduced by reducing the relative rotation speed.
