[산업상 이용 분야][Industrial use]
본 고안은 냉각장치를 한 루쯔 송풍기(또는 진공펌프)에 관한 것이다.The present invention relates to a Lutz blower (or vacuum pump) with a cooling device.
[종래의 기술][Prior art]
종래의 루쯔 송풍기는 공기가 압축될때 발생하는 압축열과 베어링, 기어등에서 발생하는 마찰열로 인해 고진공 또는 고압을 얻기가 어려우며, 또한 이열로 인하여 송풍기의 수명이 단축될뿐만 아니라 미세한 간극(약 0,02-0,06mm)를 가진 고정부와 회전부가 열로인한 팽창으로 접촉하거나 마찰되어 고장의 원인이 되며, 이러한 문제점을 없애기 위하여서는 이의 접설 간극을 비교적 넓게 해야 하므로 이렇게 하면 기체의 압축 효율이 저하되는 폐단이 있었던 것이다.Conventional Roots blowers are difficult to obtain high vacuum or high pressure due to the heat of compression when air is compressed and frictional heat generated from bearings, gears, etc. In addition, due to this heat, the life of the blower is not only shortened but also a minute gap (about 0,02-) 0,06mm) and the rotating part are contacted or rubbing due to thermal expansion, which causes the failure, and in order to eliminate this problem, it is necessary to widen the seizure gap relatively. It was.
[본 고안이 해결하고자 하는 요지][Points to be solved by the present invention]
본 고안은 이상의 결점을 해결하고자 안출한 것으로 이의 고안 요지는 압축열과 마찰열을 냉각 시킬수 있게 임펠라와 하우징 사이에 물냉각 장치를 부여한데 특징이 있다.The present invention is devised to solve the above-mentioned drawbacks, and the subject matter of the present invention is characterized by providing a water cooling device between the impeller and the housing to cool the heat of compression and friction.
[본 고안의 해결 수단][Measures of the present invention]
이를 도면에 의거 상세히 설명하면 다음과 같다.This will be described in detail based on the drawings.
몸체(11)의 상하로 베이링(3)(3′)을 개재시켜 축설된 축(1)(1′)에 한쌍의 임펠라(2)(2′)가 연설되고 그일측에는 한쌍의 기어(4)(4′)를 착설하여 이상의 임펠라(2)(2′)가 서로 반대방향으로 맞물려 회전되게 하며 임펠라(2)(2′)를 감싸고 있는 케이싱(5)의 일측에는 공기 흡입구(6)가 형성되고 그반대편에는 흡입 압축된 공기를 배출하는 배출구(7)가 형성된 것에 있어서, 케이싱(5)의 양측벽에 비교적 넓은 전열 면적을 가진 수냉판(8)이 패킹(9)을 개재시킨 상태에서 하우징(10)에 착설하며 이 수냉판(8)의 하부에는 냉각수 인입구(8′)가 형성되고 내면에는 곡선상의 냉각수통로(8′)가 형성되며, 상부에는 냉각수 배출구(8″)가 형성된 구조이다.A pair of impellers (2) (2 ') are spoken to the shaft (1) (1') arranged through the bearing (3) (3 ') up and down of the body (11), and on one side there is a pair of gears ( 4) (4 ') is installed so that the above impellers (2) and (2') rotate in opposite directions to each other and the air inlets (6) on one side of the casing (5) surrounding the impellers (2) and (2 '). Is formed and the opposite side is provided with a discharge port 7 for discharging the compressed air, the water cooling plate 8 having a relatively large heat transfer area on both side walls of the casing 5 with the packing 9 interposed therebetween. In the housing 10, the cooling water inlet 8 'is formed at the lower portion of the water cooling plate 8, and a curved cooling water passage 8' is formed at the inner side, and the cooling water outlet 8 " is formed at the upper portion thereof. Structure.
이상과같이 구성된 본 고안을 실시함에 있어서, 흡인구(6)를 통해 흡입된 공기를 임펠라(2)에서 압축하며 배출구(7)로 배출되는 과정 발생하는 열을 냉각시킴에 있어, 제2도에 표시된 바와같이 케이싱(5) 하부의 인입구(8′)에서 들어온 냉각수가 곡선상으로 배치된 냉각판(8)의 냉각수통로(8″)를 따라 통과하는 과정 임펠라(2)와 기어(4)(4′)에서 생긴 열을 흡수한 상태에서 배출구(8″)로 배출하게 되므로, 유입된 공기의 압축을 함에 있어서 보다 많은 고진공이나 고압을 얻을수 있고 또한 고열로 인한 팽창으로 생기는 기계적 마찰을 최대한 방지할 수가 있음은 물론 고정체와 가동체의 설치 간극을 최소로할 수 있어서, 기체의 압축 효율을 최대한 높힐수 있다.In carrying out the present invention configured as described above, in the process of compressing the air sucked through the suction port (6) in the impeller (2) and the heat generated in the process discharged to the discharge port (7), Cooling water coming from the inlet 8 'under the casing 5 passes along the cooling water passage 8 ″ of the cooling plate 8, which is arranged in a curved manner, as shown. 4 ') is discharged to the outlet (8 ″) in the state of absorbing the heat generated in the 4'), it is possible to obtain more high vacuum or high pressure in the compression of the inlet air, and to prevent the mechanical friction caused by the expansion due to high heat In addition, the gap between the fixture and the movable body can be minimized, and the compression efficiency of the gas can be maximized.
그리고 냉각수 통로(8″)를 하우징(10)에 설치해도 동일한 기능을 달성할 수 있다.The same function can be achieved by providing the cooling water passage 8 ″ in the housing 10.
[본 고안의 효과][Effect of this invention]
이상과같이 본 고안은 케이싱(5)과 하우징(10) 사이에 냉각판(8)을 설치하여 압축시 생기는 열과 기어(4)(4′)의 회동 과정 생기는 마찰열 또는 열팽창으로 인하여 생기는 기계적 습찰등을 방지할수 있게 하였기 때문에 산업적으로 크게 기여할 수 있다.As described above, the present invention provides a mechanical learning method caused by frictional heat or thermal expansion caused by heat generated during compression and rotation of the gears 4 and 4 ′ by installing the cooling plate 8 between the casing 5 and the housing 10. This makes it possible to make a significant industrial contribution.
