터보압축기 누설 방지 구조.{Structure for leak prevention Turbo Compressor}Structure for leak prevention Turbo Compressor}

본 발명은 고속 회전 임펠러를 이용하여 유체를 가압하는 터보압축기 누설 방지 구조에 관한 것으로 써, 특히 압축기의 회전축을 오일부와 압축 유체부로 나누어 분리시키고, 시일하는 과정에서 압축 유체의 대기 누설 및 외부 유체의 혼입 오염을 최소화 하도록 시일 하는 부분의 주변 구조에 관한 것이다.The present invention relates to a turbocompressor leakage preventing structure for pressurizing a fluid by using a high-speed rotating impeller. In particular, the rotary shaft of the compressor is divided into an oil portion and a compressed fluid portion, and the air leakage and external fluid of the compressed fluid are separated during the sealing process. The involvement of the surrounding structure of the sealing part to minimize contamination.

압축기는 기계적 에너지를 이용하여 유체를 가압하여 유체의 압축에너지로 변환 시키는 것으로, 그 종류는 일반적으로 왕복동식, 베인식, 원심회전식, 스크롤식으로 구분되며; 원심력압축기는 임펠러의 회전력을 이용하여 유체를 축 방향으로 흡입하여 원심방향으로 고속 토출 시키면서 유체를 압축하는 압축기로써, 통상적으로 터보압축기로 호칭 되며, 복수의 임펠러를 각각의 단으로 구성하여 대용량의 기체를 압송하는 다단터보압축기가 사용된다.Compressors use mechanical energy to pressurize a fluid and convert it into compressed energy of the fluid, which is generally classified into a reciprocating type, a vane type, a centrifugal type, and a scroll type; Centrifugal force compressor is a compressor that compresses the fluid by sucking the fluid in the axial direction and discharging the fluid at high speed in the centrifugal direction by using the rotational force of the impeller. The centrifugal compressor is generally referred to as a turbo compressor. Multi-stage turbocompressors are used to pump them.

다단터보압축기의 일반적인 구성 및 동작을 살펴보면 구동력을 전달하는 구동축에 연결된 불기어와 불기어의 기어 치형에 맞물려 동작하는 다수개의 피니언축으로 동력이 전달되고, 상기 피니언축에 연결되는 임펠러의 회전운동으로 유체를 강제 압송하여 고압의 유체를 생성하게 되지만 1개의 임펠러에서 생성가능한 압력은 한계가 있기에 상기 다수개의 피니언축에 각각의 임펠러를 조립하여 (통상 1단에서 3단의 구성을 갖게 된다) 운전하게 되는데, 이를 동작순서로 살펴보면 1단임펠러에서 일반유체를 압축하여 1차 쿨러로 압송하고 1차 쿨러에 압송된 압축 유체는 2단 임펠러에서 상기 1단 임펠러의 압력보다 고압으로 압축되어 2차 쿨러에 압송되며 2차 쿨러에 압송된 고압의 유체는 다시 3단 임펠러에서 상기 2단 임펠러의 압력보다 고압으로 압축되어 사용처로 토출되는 사이클을 가지고 동작하게 된다.Looking at the general configuration and operation of the multi-stage turbo compressor, the power is transmitted to a plurality of pinion shafts that are engaged with the gear gears of the gears and the gears connected to the drive shaft that transmits the driving force, and the rotary motion of the impeller connected to the pinion shaft The forced pressure of the fluid produces a high-pressure fluid, but the pressure that can be generated by one impeller is limited, so each impeller is assembled to the plurality of pinion shafts (usually having one to three stages) to operate. In the operation sequence, the first fluid is compressed into a primary cooler by compressing the general fluid in the first stage impeller, and the compressed fluid delivered to the primary cooler is compressed to a higher pressure than the pressure of the first stage impeller in the second stage impeller. The high pressure fluid, which is pumped to the secondary cooler, is pressurized again at higher pressure than the pressure of the second stage impeller in the third stage impeller. It is are operated with a cycle in which the ejection to the point of use.

상기와 같은 사이클에서 각단의 임펠러 내부의 압력증가에 따라 유체의 누설을 방지하기 위하여 비접촉으로도 우수한 시일 효과를 가지는 레비린스시일을 사용하지만 레비린스시일이 실링 가능한 압력이상의 압력이 발생 되는 협소한 공간에서 누설이 발생하지 않을 수 없다.In the cycle as described above, in order to prevent the leakage of fluid due to the increase in the pressure inside the impeller at each stage, the levyrinse seal which has excellent sealing effect is used even in non-contact, but the narrow space where the pressure above the pressure at which the levyrinse seal can be sealed is generated. Leakage must occur at the

특허문헌 3 대한민국 특허청 특허공보 특 2001-0010873에 공개된 바와 같이, 축방향 실링 구조는 포일 베어링을 사용하여 구동축의 반경 방향을 지지하는 구조에서 상기 구동축의 외주면에 모터실을 기준으로 축의 회전방향에 대해 순 반향으로 가스 흡입용 그루브를 형성함으로써, 상기 구동축이 실링부재에 부딪히는 것을 최대한 방지하면서도 상기한 가스흡입용 그루브가 모터실에 냉매가스를 임펠러의 배면쪽으로 몰아내게 되어 압축가스가 임펠러의 배면을 타고 모터실로 누설되려는 것을 방지하는 터보 압축기의 축 방향 실링 구조 등이 공개되어 있음을 알 수 있다.Patent Document 3 As disclosed in Korean Patent Application Laid-Open No. 2001-0010873, the axial sealing structure uses a foil bearing to support the radial direction of the drive shaft in the direction of rotation of the shaft relative to the motor chamber on the outer circumferential surface of the drive shaft. By forming a gas suction groove in the forward direction, the gas suction groove drives the refrigerant gas to the rear of the impeller in the motor chamber while preventing the driving shaft from hitting the sealing member as much as possible. It can be seen that the axial sealing structure of the turbocompressor, which prevents leakage into the motor compartment of the vehicle, is disclosed.

종래에는 상기와 같은 수단들을 이용하여 터보압축기의 유체 누설을 감소시키려는 노력이 있어 왔지만, 레비린스시일을 가압하기 위하여 질소(N2),스팀(H2O)및 냉매가스등 외부의 기체를 이용, 가압하는 경우는 사용되는 압축 유체에 다른 성질의 유체가 혼입되어 압축기의 적용범위에 상당한 제약을 받을 수 있고;Conventionally, efforts have been made to reduce the fluid leakage of the turbocompressor using the above means, but in order to pressurize the levy rinse seal, an external gas such as nitrogen (N2), steam (H2O), and refrigerant gas is used to pressurize. In some cases, fluids of different properties may be incorporated into the compressed fluid used, which may result in significant limitations in the application of the compressor;

밸런스실과 유체유동도관 및 압력원을 이용; 임펠러와 슈라우드간의 간극을 조절한 경우는 누설을 막기 위한 것보다는 압축효율이 떨어지는 것을 방지하기 위한 것으로, 축방향 추력 발생시 로터의 중앙에 구성된 휠에 부하가 발생하여 동력손실을 야기 함을 알 수 있으며;Using balance chambers, fluid flow conduits and pressure sources; If the gap between the impeller and the shroud is adjusted, it is to prevent the compression efficiency from dropping rather than to prevent leakage, and it can be seen that when the axial thrust occurs, a load is generated on the wheel configured in the center of the rotor, causing power loss. ;

축의 회전방향에 대하여 순 방향으로 가스 그루브를 형성하는 것은, 그루브에서 발생하는 유체저항에 대한 동력원 손실 및 임펠러 구동축에 진동을 야기시켜 고속회전시 불안정한 상태를 제공하여 오히려 안전에 위협이 되는 요인이라는 것을 알 수 있다.Forming a gas groove in the forward direction with respect to the rotational direction of the shaft causes a loss of power source for the fluid resistance generated in the groove and vibration in the impeller drive shaft, thus providing an unstable state at high speed, which is a threat to safety. Able to know.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로 써, 터보압축기에 있어서, 임펠러의 흡입 압축 토출의 과정에서 압축실의 압력이 증가함에 따라 레비린스시일의 가압용량을 초과하여 압축 유체가 임펠러의 배면을 따라 축 방향으로 대기중에 누설되는 것을 방지하고; 시일하는 과정에서 외부유체가 혼입되어 압축유체가 오염되지 않도록 방지함과 동시에 로터측에 진동 및 저항에 따른 부하가 발생하지 않는 터보압축기의 누설방지구조를 제공하는 것을 발명의 목적으로 한다.The present invention has been made to solve the above problems, in the turbocompressor, as the pressure of the compression chamber increases in the process of suction compression discharge of the impeller, the compressed fluid exceeds the pressure capacity of the levirin seal seal impeller Prevent leakage in the air in the axial direction along the back surface of the surface; It is an object of the present invention to provide a leakage preventing structure of a turbocompressor, in which external fluid is mixed in a sealing process to prevent contamination of the compressed fluid and at the same time a load due to vibration and resistance is not generated on the rotor side.
