터어보차져의 보호장치Turbocharger protection

제1도는 종래의 터어보차져 장치를 도시하는 개략도.1 is a schematic diagram showing a conventional turbocharger device.

제2도는 본 고안의 실시예에 의한 터어보차져의 보호장치를 도시하는 개략도.2 is a schematic diagram showing a protection device of a turbocharger according to an embodiment of the present invention.

제3도는 본 고안의 작동상태를 설명한 구성도.3 is a configuration diagram illustrating the operating state of the present invention.

본 고안은 터어보차져를 보호하기 위한 장치에 관한 것으로, 특히 오일공급파이프내의 오일을 기관 시동과 동시에 터어보차져내에 주사시킴으로써 터어보차져의 베어링부 윤활을 도모하고 터어보차져의 윤활부족에 의한 베어링의 소손을 방지하도록 한 터어보차져의 보호장치에 관한 것이다.The present invention relates to a device for protecting a turbocharger. In particular, the oil in the oil supply pipe is injected into the turbocharger at the same time as the engine is started to promote lubrication of the bearing part of the turbocharger and due to the lack of lubrication of the turbocharger. A turbocharger protection device is provided to prevent burnout of a bearing.

제1도는 종래 터어보차져장치를 도시한 개략도로서, 흡기관(3)을 갖고 흡기구(1a)로 부터 공기를 흡입하는 터어보차져 압축기(1)와, 배기관(4)을 갖고 배기구(5a)로 배기가스를 배출하는 터어보차져 터어빈(5)과, 이 터어보차져 터어빈(5)과 상기 터어보차져 압축기(1)내에서 회전하는 각각의 터어빈휠(2A)과 압축기휠(2B)은 휠축(S)의 양단에 장착되어 있고, 이 휠축(S)은 터어보차져내에 장착된 베어링(6)에 회전지지되어 있고, 이 베어링(6)에 오일을 주입하여 배출토록하는 오일공급파이프(7)와 오일리턴파이프(8)로 구성되어 있다.FIG. 1 is a schematic view showing a conventional turbocharger device, which has a turbocharger compressor 1 having an intake pipe 3 and inhaling air from the intake port 1a, and an exhaust port 5a having an exhaust pipe 4; The turbocharger turbine 5 which discharges the exhaust gas into the furnace, and the turbocharger turbine 5 and the respective turbine wheels 2A and the compressor wheel 2B which rotate in the turbocharger compressor 1 are It is mounted on both ends of the wheel shaft S, and the wheel shaft S is rotatably supported by the bearing 6 mounted in the turbocharger, and the oil supply pipe which injects oil into the bearing 6 and discharges it ( 7) and the oil return pipe (8).

상기와 같이 구성된 종래의 터어보차져는 기관의 배기가스의 배기열에 의해 구동되는 유체기계식 기계장치로, 배기관(4)을 통해 배출된 배기가스의 열에너지에 의해 터어보차져 터어빈(5)내의 터어빈휠(2A)에 위해 휠축(S)이 회전하고 대기상태의 공기가 터어빈휠(2B)의 회전에 의해 터어보차져 압축기(1)의 흡기구(1a)를 통해 강제 압축흡입되어 기관의 흡기관(3)내에 강제 흡입되게 된다. 이때 회전되는 터어보차져 휠(2A,2B)은 보통 9만 rpm 이상을 상회하고 있어, 터어보차져의 휠축(S)을 회전지지하는 베어링(6) 부위에 윤활이 원활하지 않을 때는 순간적인 베어링(6) 손상이 발생하여 결국 고가의 터어보차져에 치명적인 결함을 가져오게 된다.The conventional turbocharger configured as described above is a fluid mechanical device driven by the exhaust heat of the exhaust gas of the engine, and is turbocharged by the thermal energy of the exhaust gas discharged through the exhaust pipe 4 and the turbine wheel in the turbine 5. The wheel shaft S is rotated for 2A, and atmospheric air is blown by the rotation of the turbine wheel 2B, forcibly compressed and sucked through the inlet 1a of the compressor 1, and the intake pipe 3 of the engine Forced inhalation). At this time, the turbocharger wheels 2A and 2B rotated are usually higher than 90,000 rpm, and when the lubrication is not smooth to the bearing 6 portion that supports the wheel shaft S of the turbocharger, the instantaneous bearing (6) Damage will occur, resulting in a fatal defect in the expensive turbocharger.

이러한 결함을 방지하기 위해 기관의 주통로에서 공급되는 오일은 오일공급파이프(7)를 통해 터오보 차져에 공급되어 터어보 차져의 베어링에 공급토록하여 터어보차져를 윤활시킨후 리턴파이프(8)를 통해 흘러내려가 기관의 오일팬에 자유낙하하여 계속되는 기관의 운전에 의해 계속 순환하게 된다.In order to prevent this defect, the oil supplied from the main passage of the engine is supplied to the turbocharger through the oil supply pipe (7) to supply the bearing of the turbocharger to lubricate the turbocharger, and then return the pipe (8). It flows down through and free-falls into the engine's oil pan, which continues to circulate by the engine's continued operation.

그러나 기관의 운전이 잦을시는 오일의 순환이 원활하여 터어보차져내의 윤활이 정상적이지만, 기관이 장기간 가동되지 않아 베어링부의 오일 부족현상이 발생될 경우나 동절기시의 오일점도에 의해 오일공급이 원활하지 않을 경우에 시동과 동시에 기관의 회전이 급상승함에 따라 발생된 마찰열로 인하여 베어링부의 손상을 초래하는 문제점을 갖고 있다.However, when the engine is frequently operated, the oil is smoothly circulated and the lubrication in the turbocharger is normal.However, when the engine is not operated for a long time, oil shortage occurs in the bearing part or oil viscosity during the winter is smooth. If not, there is a problem in that the bearing portion is damaged due to the frictional heat generated as the rotation of the engine rapidly increases at the same time as starting.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 그 목적은 기관회전이 상승에 따라 터어보차져의 베어링부위에 윤활을 도모하여 내구신뢰성을 향상시키고 또한 고가의 터어보차져의 손상을 방지하는 터어보차져의 보호장치를 제공함에 있다.The present invention is to solve the above problems, the purpose of the engine rotation is to increase the lubrication of the bearing portion of the turbocharger as the engine rotation increases the durability of the turbocharger to prevent damage to the expensive turbocharger To provide the protection of the avocharger.

상기의 목적을 달성하기 위한 본 고안의 구체적인 수단은, 기관의 시동과 정지를 전기식으로 작동시키는 키스위치와 함께 병렬로 접속되어 작동되는 온/오프식 솔레노이드밸브에 의해서 기관의 운전기관으로 부터 공급되는 오일을 오일공급파이프를 통하여 터어보차져의 베어링 부위에 주입토록 하여서 달성된다.Specific means of the present invention for achieving the above object is supplied from the engine of the engine by an on / off solenoid valve which is connected and operated in parallel with a key switch for electrically starting and stopping the engine. This is accomplished by injecting oil through the oil supply pipe into the bearing area of the turbocharger.

이하 첨부된 도면을 참조하여 본 고안의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제2도 및 제3도는 제1도와 동일 부분을 같은 부호로 사용한다.2 and 3 use the same parts as those in FIG. 1.
