Field of the Invention The present invention relates to a turbocompressor with a variable diffuser, and more particularly to a turbocompressor with a variable diffuser adapted to change the surge area or improve the efficiency at a particular operating point by changing the angle of the vanes.

일반적으로, 외부 공기를 압축시키기 위해서는 피스톤식 압축기, 로터식 압축기, 터보식 압축기 등이 있는데, 터보식 압축기의 경우 고속으로 회전하는 회전축에 연결된 임펠러에 의해 외부 공기가 압축된다. 상기 터보식 압축기는 일반 산업 현장에서부터 항공기의 엔진 부문에 이르기까지 다양한 산업 분야에서 공기를 포함한 여러 종류의 가스를 압축하기 위해 사용되는 중요한 요소 기계이다. In general, in order to compress the outside air, there are a piston compressor, a rotor compressor, a turbo compressor, and the like. In the case of the turbo compressor, the outside air is compressed by an impeller connected to a rotating shaft rotating at high speed. The turbo compressor is an important element machine used to compress various kinds of gases including air in various industrial fields from general industrial sites to the engine sector of aircraft.

도1은 종래 터보 압축기의 개념도이다. 도1에 도시한 바와 같이, 상기 터보 압축기는 구동축(driving shaft:1)에 결합되며 원주 방향으로 형성된 다수개의 블레이드(11)를 가진 임펠러(impeller:10), 상기 임펠러(10)의 외주에 형성된 가변 디퓨저(variable diffuser:20) 및 상기 가변 디퓨저(20)의 원주 방향으로 다수개가 형성되는 베인(vane:30)을 포함하여 이루어진다. 1 is a conceptual diagram of a conventional turbo compressor. As shown in FIG. 1, the turbo compressor is coupled to a driving shaft 1 and has an impeller 10 having a plurality of blades 11 formed in a circumferential direction, and formed on an outer circumference of the impeller 10.

도2에 도시한 바와 같이, 본 발명에 따른 가변 디퓨저를 구비한 터보 압축기는, 종래의 터보 압축기와 마찬가지로, 임펠러(100)와, 상기 임펠러(100)의 외주에 형성되는 가변 디퓨저(110)와, 상기 가변 디퓨저(110)의 원주 방향으로 다수개가 형성되는 베인(120)을 포함하여 이루어지는데, 특별히 상기 베인(120)은 양측단에 두개의 피봇(121,122)을 구비하고 있다. 즉, 임펠러(100)에서 토출되는 고속 유체로부터 강한 토크를 효과적으로 견딜 수 있도록, 베인(120)의 양측단에는 두개의 피봇(121,122)이 설치되어 있는 것이다. As shown in FIG. 2, the turbo compressor including the variable diffuser according to the present invention includes an impeller 100 and a variable diffuser 110 formed on an outer circumference of the impeller 100, as in the conventional turbo compressor. In addition, the vane 120 includes a plurality of vanes 120 formed in a circumferential direction of the variable diffuser 110. In particular, the vanes 120 are provided with two pivots 121 and 122 at both ends thereof. That is, two pivots 121 and 122 are installed at both ends of the vanes 120 so as to effectively withstand the strong torque from the high velocity fluid discharged from the impeller 100.

이때, 상기 하나의 피봇(121)은 베인(120)의 전측단에 위치하는 고정 피봇(fixed pivot)이고, 상기 다른 하나의 피봇(122)은 베인(120)의 후측단에 위치하는 이동 피봇(moving pivot)이다. In this case, the one pivot 121 is a fixed pivot located at the front end of the vane 120, and the other pivot 122 is a moving pivot located at the rear end of the vane 120. moving pivot).

도3에 도시한 바와 같이, 본 발명에 따른 가변 디퓨저를 구비한 터보 압축기는, 상기 베인(120)의 각도를 변화시킬 수 있도록, 스텝 모터 즉, 구동 모터(미도시), 웜 기어(130) 및 스퍼 기어(140,150)를 포함하여 이루어진 변각 메커니즘을 구비한다. 도면부호 "131"은 포텐셔미터(Potentiometer), "132"는 베어링(Bearing), "133"은 부싱(Bushing)이다.
