Description

로터리 베인형 진공펌프 장치{Rotary vane type vacuum pump device}Rotary vane type vacuum pump device

본 고안은 로터리 베인형 진공펌프 장치에 관한 것으로, 특히 방열(放熱)에 유리한 접속구조를 갖도록 설계된 로터리 베인형 진공펌프 장치에 관한 것이다.The present invention relates to a rotary vane type vacuum pump device, and more particularly, to a rotary vane type vacuum pump device designed to have a connection structure advantageous for heat dissipation.

로터리 베인형 진공펌프 장치는, 일반적으로, 그 표면에 베인이 장착된 로터를 포함하는 펌프와 상기 펌프에 밀접하게 결합되어 로터를 회전시키는 구동 모터로 이루어 지며, 로터의 회전에 따라 공기가 펌프의 흡입포트 측으로 유입되고 펌프 내에서 압축되어 배출포트를 통해 배출되는 원리로 작동한다.The rotary vane type vacuum pump apparatus generally includes a pump including a rotor having vanes mounted on a surface thereof, and a driving motor coupled to the pump to rotate the rotor. It operates on the principle of entering into suction port side, compressed in pump and discharged through discharge port.

상기 진공펌프 장치가 작동하는 동안, 모터는 그 자체에서 발생하는 열과 펌프로부터 전도되는 열로 인하여 과열되기 쉽다. 그리고 과열은 당연하게 상기 장치, 특히 모터의 수명을 단축시키는 결과를 초래하므로, 그 열을 효과적으로 방출시킬 필요가 있다.While the vacuum pump device is in operation, the motor is prone to overheating due to the heat generated by itself and the heat conducted from the pump. And overheating naturally results in shortening the life of the device, in particular the motor, so it is necessary to effectively dissipate the heat.

열의 방출을 위하여 상기 모터의 하우징에 방열핀이 형성된 것이 통상적으로 사용된다. 상기 방열핀은 모터 하우징의 대기 접촉면적을 크게 하여 방열 효율을 높여주는 역할을 한다. 그러나 이러한 방열핀 만으로는, 모터 자체에서 발생하는 열과 펌프로부터 전도되는 열을 동시에 효과적으로 방출시키기 어렵다.It is commonly used that a heat radiation fin is formed in the housing of the motor for dissipation of heat. The heat dissipation fins serve to increase heat dissipation efficiency by increasing the atmospheric contact area of the motor housing. However, such a heat radiation fin alone, it is difficult to effectively release the heat generated from the motor itself and the heat conducted from the pump at the same time.

본 고안은 상기한 종래 기술의 문제점을 해결하기 위하여 고안된 것으로, 펌프와 모터의 결합구조를 특히 방열에 유리하도록 설계한 로터리 베인형 진공펌프 장치를 제공하고자 한다.The present invention has been devised to solve the above problems of the prior art, and to provide a rotary vane type vacuum pump device designed to be particularly advantageous for heat dissipation of the coupling structure of the pump and the motor.

본 고안 진공펌프의 구조에서, 제1플레이트와 제2플레이트는 그 표면이 대기와 접촉하게 된다. 따라서 모터부 내부에서 발생하는 열은 제1플레이트 표면으로부터 방열될 수 있으며, 펌프부 내부에서 발생하는 열은 모터부로 전도되지 않고 제1플레이트 표면으로부터 방열된다.In the structure of the vacuum pump of the present invention, the surfaces of the first plate and the second plate come into contact with the atmosphere. Therefore, heat generated inside the motor portion may be radiated from the surface of the first plate, and heat generated inside the pump portion is radiated from the surface of the first plate without being conducted to the motor portion.

이상의 본 고안의 구조적 특징과 작용효과는, 첨부도면에 의해 참조되는 실시예를 들어 설명하는 이하의 기재를 통하여 보다 명백해 질 것이다. 참고로, 도 1은 본 고안에 따른 실시예의 사시도이고, 도 2는 도 1의 분해 사시도, 도 3은 도 1의 정면도이다.The structural features and effects of the present invention will become more apparent through the following description given by way of example with reference to the accompanying drawings.

상기 펌프부(20)는 펌프 하우징(21)과, 상기 펌프 하우징(21)의 전면에 결합되는 전면커버(27)로 이루어 진다. 상기 펌프 하우징(21)은 내부 수납실(22)과 흡입포트(23) 및 배출포트(24)를 가지며, 상기 수납실(22)에는 상기 모터 축(13)에 회전 가능하게 연결되는 로터(25)가 장착되고, 로터(25)의 표면 홈에 베인(26)이 설치된다. 상기 베인(26)은 통상의 카본(carbon)이다.The pump unit 20 is composed of a pump housing 21, the front cover 27 is coupled to the front of the pump housing 21. The pump housing 21 has an inner storage chamber 22, a suction port 23, and a discharge port 24, and a rotor 25 rotatably connected to the motor shaft 13 in the storage chamber 22. ) Is mounted, and a vane 26 is installed in the surface groove of the rotor 25. The vanes 26 are ordinary carbon.

상기 접속부(30)는 상기 모터 하우징(11)의 개방측과 상기 펌프 하우징(21)의 개방측 사이에 배치되며, 상기 모터 하우징(11)의 개방측을 덮는 형태의 제1플레이트(31)와 상기 펌프 하우징(21)의 개방측을 덮는 형태의 제2플레이트(32) 및 상기 대향된 제1, 2플레이트(31,32) 간을 연결하는 리브(33)로 이루어 진다. 중앙에는 상기 모터 축(13)이 관통하는 홀(34)이 형성되어 있다. 상기 리브(33)에 의해, 상호 연결된 제1, 2플레이트(31,32)는 각각의 표면이 대기와 접촉해 있게 된다.The connection part 30 is disposed between the open side of the motor housing 11 and the open side of the pump housing 21, and covers the open side of the motor housing 11. It consists of a second plate 32 of the form covering the open side of the pump housing 21 and the rib 33 for connecting between the opposing first and second plates (31,32). In the center is formed a hole 34 through which the motor shaft 13 passes. By means of the ribs 33, the surfaces of the interconnected first and second plates 31 and 32 are in contact with the atmosphere.

이와 같이 구성되는 진공펌프 장치(1)는, 모터(12)의 회전과 그에 따른 로터(25)의 회전에 의해 공기가 펌프 하우징(21)의 흡입포트(23) 측으로 유입되고 펌프부(20) 내에서 압축되어 배출포트(24)를 통해 배출되는 원리로 작동한다. 다만, 이 작동 원리는 본 고안에서 특이한 것은 아니므로 더 이상의 구체적인 설명은 생략한다.In the vacuum pump device 1 configured as described above, air is introduced into the suction port 23 side of the pump housing 21 by the rotation of the motor 12 and the rotation of the rotor 25. Compressed in the inside operates on the principle that is discharged through the discharge port (24). However, this principle of operation is not peculiar to the present invention, so a detailed description thereof will be omitted.

위와 같이 상기 진공펌프 장치(1)가 작동하는 동안, 모터부(10)와 펌프부(20)는 모터(12)와 로터(25)의 회전으로 인하여 그 내부에서 열이 발생된다. 한편, 접속부(30)의 제1, 2플레이트(31,32)는 리브(33)에 의해 각각의 표면이 대기와 접촉해 있다. 따라서 작동 중 상기 모터부(10)에서 발생된 열은 모터 하우징(11)과 제1플레이트(31)의 표면으로부터 외부로 방열되며, 또한 펌프부(20)에서 발생된 열은 상기 모터부(10)로 전도되지 않고 제2플레이트(32)의 표면으로부터 외부로 방열된다.While the vacuum pump apparatus 1 operates as described above, heat is generated in the motor unit 10 and the pump unit 20 due to the rotation of the motor 12 and the rotor 25. On the other hand, the surfaces of the first and second plates 31 and 32 of the connecting portion 30 are in contact with the atmosphere by the ribs 33. Therefore, the heat generated in the motor unit 10 during operation is radiated to the outside from the surface of the motor housing 11 and the first plate 31, and the heat generated in the pump unit 20 is the motor unit 10 Heat is radiated to the outside from the surface of the second plate 32 without being conducted.

본 고안에 따르면, 모터부(10)와 펌프부(20)의 각 내부에서 발생되는 열은그들(10,20) 사이에 배치되는 접속부(30)의 제1, 2플레이트(31,32)의 표면으로부터 외부로 방열된다. 따라서 진공펌프 장치(1), 특히 모터부(10)가 과열되지 않는 효과가 있다.According to the present invention, the heat generated in each of the motor unit 10 and the pump unit 20 is generated by the first and second plates 31 and 32 of the connection unit 30 disposed between them. It radiates heat from the surface to the outside. Therefore, there is an effect that the vacuum pump device 1, in particular the motor unit 10 is not overheated.
