일반적으로 횡형 로터리 압축기는 압축기 내부의 주요 마찰부위를 윤활하기 위하여 입형 로터리 압축기와는 달리 주요 마찰부위가 냉동기유의 윤활유레벨 보다 높게 위치하고 있어서 원할한 압축기의 운전을 위해 별도의 급유구조가 필요 하였다.In general, in the horizontal rotary compressor, unlike the vertical rotary compressor, the main frictional portion is located higher than the lubricating oil level of the refrigeration oil to lubricate the main frictional portion of the compressor. Therefore, a separate lubrication structure was required for smooth operation of the compressor.

Lubricating oil supply pipe (11) for introducing the lubricating oil (9) using the dynamic pressure and the lubricating oil (9) introduced into the lubricating oil supply pipe (11) is stored to supply the lubricating oil (9) to each sliding part requiring lubrication It consists of a lubricating oil supply passage 12 and an internal supply pipe 13.
상기한 종래의 윤활유 분사방식 압축기는, 압축기의 가동시 모터(4)의 회전에 의해 모터(4) 내측의 회전자(3)가 회전하고 이에 연결된 편심회전축(5)은 실린더(7)내의 로울러(6)를 회전시켜 흡입된 냉매 가스를 압축한다. 상기 압축된 냉매가스는 메인베어링(MB)측에 설치된 머플러(8)를 통과 한 후 서브베어링(SB)의 토출 포트(port)를 통하여 토출되고, 세관으로 된 냉매토출파이프(10)로 유출되고 상기 유출된 고 속의 냉매가스는 압축기 저부의 윤활유(9)와 혼합되는데 이때 토출되는 가스의 분사력 내지 토출 압력에 의하여 일정 유면을 갖는 윤활유(9)중에 잠기는 윤활유급유파이프(11)의 내부에 저압이 형성됨으로써 윤활유(9)는 윤활유급유파이프(11)를 통해 편심회전축(5) 끝단의 윤활유급유로(12)로 들어가 압축기의 각 습동부로 공급되어 윤활작용을 하게 된다.In the conventional lubricating oil jet compressor, the rotor 3 inside the motor 4 rotates by the rotation of the motor 4 when the compressor is operated, and the eccentric rotation shaft 5 connected thereto is a roller in the cylinder 7. (6) is rotated to compress the sucked refrigerant gas. The compressed refrigerant gas is discharged through the discharge port of the sub-bearing (SB) after passing through the muffler (8) installed on the main bearing (MB) side, and is discharged to the refrigerant discharge pipe 10 made of tubules The leaked high-speed refrigerant gas is mixed with the lubricating oil 9 at the bottom of the compressor.

그러나, 상기한 바와 같은 급유구조는 냉매토출파이프에서 유출되는 압축냉매가스에 윤활유가 빨려들어갈 때 소음이 많이 발생하는 단점이 있었으며, 또한 냉매토출파이프에서 유출된 냉매가스의 압력맥동 성분에 의해 윤활유가 거품화되어 급유상승을 저하시킴에 따라 압축기의 성능과 신뢰성이 저하되는 문제점이 있었다.However, the lubricating oil structure as described above has a disadvantage in that a lot of noise occurs when the lubricant is sucked into the compressed refrigerant gas flowing out of the refrigerant discharge pipe, and the lubricant oil is caused by the pressure pulsation component of the refrigerant gas flowing out of the refrigerant discharge pipe. There is a problem in that the performance and reliability of the compressor is lowered as the foaming lowers the oil supply rise.

이러한 본 고안의 다른 목적은 상기 냉매토출파이프상에 형성되는 윤활유흡입관은 냉매토출파이프와 약 45도의 각도로 형성되어지는 것에 의해 달성된다.Another object of this invention is achieved by the lubricating oil suction pipe formed on the refrigerant discharge pipe being formed at an angle of about 45 degrees with the refrigerant discharge pipe.

도시된 바와 같이 압축기 본체(20)의 밀폐용기(30) 내측에 구비된 윤활유급유로(50)에 C형의 윤활유급유파이프(70)가 연결되고, 상기 윤활유급유파이프(70) 하단은 밀폐용기(30) 저면에 일정 유면으로 고여있는 윤활유(80)에 잠겨 있다. 상기 윤활유(80)에 잠겨있는 윤활유급유파이프(70)의 끝단은 압축실에서 압축된 고온 고압의 냉매가스가 토출되는 냉매토출파이프(60)의 일단이 삽입된 상태로 밀폐되어 있다. 상기 냉매토출파이프(60)의 파이프 중간에는 상기 냉매토출파이프(60)와 약 45도 각도로 냉매토출파이프(60) 단면적의 30% 이내의 단면적을 갖는 윤활유흡입관(62)이 밀폐용기(30) 저면의 윤활유(80)에 잠겨있는 상태로 되어 있다. 도면중 미설명 부호 40은 서브베어링이다.As shown, the C type lubrication oil supply pipe 70 is connected to the lubrication oil supply path 50 provided inside the sealed container 30 of the compressor main body 20, and the lower end of the lubrication oil supply pipe 70 is closed. (30) It is immersed in the lubricating oil (80) held on a certain surface on the bottom. The end of the lubricating oil supply pipe 70 immersed in the lubricating oil 80 is sealed with one end of the refrigerant discharging pipe 60 through which the high temperature and high pressure refrigerant gas compressed in the compression chamber is discharged. In the middle of the pipe of the refrigerant discharge pipe 60, the lubricating oil suction pipe 62 having a cross-sectional area within 30% of the cross-sectional area of the refrigerant discharge pipe 60 at an angle of about 45 degrees with the refrigerant discharge pipe 60 is sealed container 30. It is in the state immersed in the lubricating oil 80 of the bottom face. In the figure, reference numeral 40 is a sub-bearing.
상기와 같이 구성된 횡형 로터리 압축기 븍유구조의 작용과정을 설명하면 다음과 같다.Referring to the operation process of the horizontal rotary compressor oil structure configured as described above are as follows.
압축기의 가동과 동시에 압축기의 압축실에서 압축된 고온, 고압의 압축냉매가스는 냉매토출파이프(60)를 통해 토출된다. 이때 상기 냉매토출파이프(60)의 중간에 형성된 윤활유흡입관(62)은 압축기의 밀폐용기(30) 저면에 고인 윤활유(80)에 잠겨있는 상태로 냉매토출파이프(60) 내부의 압축냉매가스의 흐름과 함께 상기 윤활유흡입관(62)을 통해 윤활유(80)가 흡입되어 압축냉매가스와 혼합된 상태로 냉매토출파이프(60) 끝단으로 토출된다. 상기 냉매토출파이프(60)이 끝단은 윤활유급유파이프(70)에 삽입되어 연결되므로 상기 혼합된 윤활유(80)와 냉매가스는 윤활유급유파이프(70)를 통해 윤활유급유로(50)에 전달되고 이어서 압축기 내부로 투입되어 마찰부 윤활작용을 하게 된다.Simultaneously with the operation of the compressor, the compressed high-temperature, high-pressure compressed refrigerant gas compressed in the compression chamber of the compressor is discharged through the refrigerant discharge pipe (60). At this time, the lubricating oil suction pipe (62) formed in the middle of the refrigerant discharge pipe (60) is a flow of compressed refrigerant gas inside the refrigerant discharge pipe (60) in a state of being immersed in the lubricating oil (80) accumulated on the bottom surface of the sealed container (30) of the compressor. In addition, the lubricating oil 80 is sucked through the lubricating oil suction pipe 62 and discharged to the end of the refrigerant discharging pipe 60 while being mixed with the compressed refrigerant gas. Since the end of the refrigerant discharge pipe 60 is inserted into and connected to the lubrication oil supply pipe 70, the mixed lubricant oil 80 and the refrigerant gas are transferred to the lubrication oil supply path 50 through the lubrication oil supply pipe 70. It is injected into the compressor to lubricate the friction part.
상술한 바와 같이 본 고안은 압축기의 밀폐용기 저면에 고인 윤활유에 잠기는 윤활유급유파이프의 끝단을 밀폐시키고 윤활유흡입관을 형성한 냉매토출파이프를 상기 윤활유급유파이프의 밀폐된 끝단에 삽입시켜 종래의 구성에 비하여 애매토출파이프에서 유출되는 압축냉매가스에 윤활유가 빨려들어갈 때 소음이 많이 발9생하게 되거나, 또한 냉매토출파이프에서 유출된 냉매가스의 압력맥동성분에 의해 윤활유가 거품화되어 급유상승을 저하시킴에 따라 압축기의 성능과 신뢰성이 저하되는 문제점들을 해결할 수 있는 효과의 고안이다.As described above, the present invention seals the end of the lubricating oil supply pipe immersed in the lubricating oil accumulated on the bottom surface of the airtight container of the compressor and inserts the refrigerant discharge pipe formed with the lubricating oil suction pipe to the closed end of the lubricating oil supply pipe, as compared with the conventional configuration. When the lubricating oil is sucked into the compressed refrigerant gas flowing out of the elusive discharge pipe, noise is generated a lot, or the lubricating oil is bubbled by the pressure pulsation component of the refrigerant gas flowing out of the refrigerant discharge pipe, thereby reducing the oil supply rise. Accordingly, the invention is devised to solve the problems of degrading the performance and reliability of the compressor.
