Description

에어콤프레셔{air compressor}Air compressor

본 발명은 복동실린더를 사용하여 압축공기의 공급을 보다 빠르게 한 에어콤프레셔에 관한 것으로, 더욱 상세하게는 유압실린더의 좌우에 별도의 에어펌프를 설치결합하여 피스톤이 이동할 때마다 공기탱크에 압축공기를 공급할 수 있도록 된 에어콤프레셔에 관한 것이다.The present invention relates to an air compressor that provides a faster supply of compressed air by using a double-acting cylinder, and more specifically, by installing and combining a separate air pump on the left and right sides of the hydraulic cylinder, the compressed air in the air tank every time the piston moves. It relates to an air compressor which can be supplied.

에어콤프레셔는 모터펌프를 이용하여 공기탱크에 압축공기를 저장한 후, 필요시 압축공기를 배출하여 다른 구동장치(예를 들어 자동차정비소의 에어드라이버)를 구동시키거나 다른 곳에 저장(예를 들어 스쿠버다이버용 공기통)하는데 이용되며, 일반적인 산업용 공장에서도 많이 사용되고 있다.The air compressor stores the compressed air in the air tank by using a motor pump, and then discharges the compressed air if necessary to drive another driving device (for example, an air driver in an automobile repair station) or store it elsewhere (for example, scuba It is used for divers reservoirs and is also used in general industrial plants.

또한, 치과의 치정기나 정형외과의 재활치료기 등 의료기계기구 상당부분이 인체에 무해한 압축공기를 이용하여 구동되는 방식을 사용하고 있으므로, 병원등의 실내공간에서도 에어콤프레셔를 사용하고 있다.In addition, since most of the medical machinery such as dental braces and orthopedic rehabilitation therapy devices are driven using compressed air that is harmless to the human body, air compressors are also used in indoor spaces such as hospitals.

위와 같이 다양하게 사용되는 에어콤프레셔는 일반적으로 압축효율이 낮은 공기펌프를 이용하여 탱크에 공기를 압축저장하는 방식사용하고 있었으며, 압축시 발생하는 열을 냉각시키기 위한 별도의 냉각장치가 필요했다.Various air compressors as described above were generally used to compress and store air in a tank by using an air pump having a low compression efficiency, and a separate cooling device was required to cool the heat generated during compression.

따라서, 에어콤프레셔의 효율을 증대시키기 위해 필요이상으로 큰 공기펌프를 사용하여 기기자체의 가격이 올라가고 부피가 커지는 문제점과 공기펌프 및 냉각팬이 고속회전하면서 소음을 발생시키는 문제점이 있었다.Therefore, using the air pump larger than necessary to increase the efficiency of the air compressor there is a problem that the price of the device itself is increased and bulky, and the noise generated while the air pump and the cooling fan rotates at high speed.

본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 에어콤프레셔의 효율을 증진시키면서 이때 발생하는 열을 별도의 장치없이 냉각시킬 수 있는 에어콤프레셔를 제공하는데 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide an air compressor that can cool the heat generated at this time without an additional device while improving the efficiency of the air compressor.

Automatic moisture filter 700 is installed in combination.

한편 상기 에어펌프(400, 500)의 양끝단과 유로(30, 40, 50, 60)연결부분에는 각각 체크밸브(410, 420, 430, 510, 520, 530)가 설치결합되어 있어 에어펌프(400, 500) 외부에서 유입된 공기가 공기탱크(100) 또는 유압탱크(200)로만 이동된다.Meanwhile, check valves 410, 420, 430, 510, 520, and 530 are installed and coupled to both ends of the air pumps 400 and 500 and the flow paths 30, 40, 50, and 60, respectively. , 500) the air introduced from the outside is moved only to the air tank 100 or the hydraulic tank 200.

상기 유압실린더(300)에 설치되는 피스톤(340)은 양쪽에 로드(310)가 형성되어 있으며, 상기 로드(310)의 끝단에는 제1에어펌프(400)와 제2에어펌프(500)에서 각각 왕복운동하는 피스톤(440, 540)이 결합설치되어 있다.The piston 340 installed in the hydraulic cylinder 300 has rods 310 formed on both sides thereof, and ends of the rods 310 are respectively provided in the first air pump 400 and the second air pump 500. Reciprocating pistons 440 and 540 are coupled to each other.

따라서, 상기 유압실린더(300)의 피스톤(340)이 운동일때 상기 제1에어펌프(400)와 제2에어펌프(500)의 피스톤(440, 540)도 동일방향으로 운동한다.Therefore, when the piston 340 of the hydraulic cylinder 300 is in motion, the pistons 440 and 540 of the first air pump 400 and the second air pump 500 also move in the same direction.

한편, 상기 유압실린더(300)는 좌우에 설치결합된 제1유로(10) 및 제2유로(20)에 의해 작동유가 저장된 유압탱크(200)와 연결되며, 제1유로(10)에 설치된 펌프모터(210)에 의해 작동유를 공급받는다. 이때, 상기 유로(10, 20) 사이에는 솔레노이드밸브(230)가 설치되어 있어 필요에 따라 유압탱크(200)에서 공급된 작동유의 흐름방향을 바꿀 수 있다.On the other hand, the hydraulic cylinder 300 is connected to the hydraulic tank 200 in which the hydraulic fluid is stored by the first passage 10 and the second passage 20 installed on the left and right, the pump installed in the first passage 10 The hydraulic oil is supplied by the motor 210. At this time, the solenoid valve 230 is installed between the flow path (10, 20) can change the flow direction of the hydraulic oil supplied from the hydraulic tank 200 as necessary.

상기 유압탱크(200)에 연결된 제2유로(20) 끝단에는 필터(800)가 설치되어 있어 작동유를 분사하여 배출하며, 유압탱크(200) 내부에 유압탱크(200) 단면크기와 같은 부구(600)를 설치하여 저장된 작동유가 크게 요동치지 않도록 하였다.The filter 800 is installed at the end of the second flow passage 20 connected to the hydraulic tank 200 to inject and discharge the hydraulic oil, and the inside of the hydraulic tank 200 is the same size as the cross section size of the hydraulic tank 200. ) So that the stored hydraulic fluid does not fluctuate greatly.

따라서, 상기 유압탱크(200)와 유압실린더(300)를 순환하는 작동유에 기포발생이 최소화하여 기포로 인한 유압실린더의 효율저하를 막을 수 있다.Therefore, the occurrence of bubbles in the hydraulic oil circulating the hydraulic tank 200 and the hydraulic cylinder 300 is minimized, thereby preventing the efficiency of the hydraulic cylinder due to bubbles.

한편, 제1에어펌프(400)와 제2에어펌프(500)의 일측에는 제3유로(30)와 제4유로(40)가 설치결합되어 있어 상기 유압탱크(200)와 연결된다.On the other hand, one side of the first air pump 400 and the second air pump 500, the third flow path 30 and the fourth flow path 40 is installed and coupled is connected to the hydraulic tank 200.

도 2 및 도 3는 도 1의 작동상태에 따른 유압회로도를 도시한 것으로서, 유압탱크(200)에 저장된 작동유는 펌프모터(210)에 의해 유압실린더(300)에 보내지고 상기 유압실린더(300)에 설치된 피스톤(340)을 일측방향으로 이동시킨다.2 and 3 show a hydraulic circuit diagram according to the operating state of Figure 1, the hydraulic oil stored in the hydraulic tank 200 is sent to the hydraulic cylinder 300 by the pump motor 210 and the hydraulic cylinder 300 The piston 340 installed in the to move in one direction.

이때, 상기 피스톤(340)과 로드(310)를 매개로 연결된 제1에어펌프(400)와 제2에어펌프(500)의 피스톤(440, 540)은 상기 피스톤(340)과 동방향으로 이동하여, 에어펌프(400, 500)내부의 공기를 압축한다.At this time, the pistons 440 and 540 of the first air pump 400 and the second air pump 500 connected through the piston 340 and the rod 310 are moved in the same direction as the piston 340. Compresses the air inside the air pumps 400 and 500.

도 2에서와 같이 펌프모터(210)에 의해 제1유로(10)로 작동유가 공급되어 유압실린더(300)의 피스톤(340)이 제2에어펌프(500)방향으로 이동할 경우에는 제2에어펌프(500)의 피스톤(540)에 의해 압축된 공기가 제6유로(60)를 통해 공기탱크(100)에 저장되며, 제1에어펌프(400)의 피스톤(440)에 의해 압축된 공기는 제3유로(30)를 통해 유압탱크(200)로 보내져 뜨거운 작동유를 냉각시킨다.As shown in FIG. 2, when the hydraulic oil is supplied to the first flow path 10 by the pump motor 210, the piston 340 of the hydraulic cylinder 300 moves in the direction of the second air pump 500. Air compressed by the piston 540 of the 500 is stored in the air tank 100 through the sixth flow path 60, and the air compressed by the piston 440 of the first air pump 400 is It is sent to the hydraulic tank 200 through the three passages 30 to cool the hot working oil.

이때, 피스톤(340)에 의해 유압실린더(300)의 내부압력이 높아지면 솔레노이드밸브(230)의 방향이 바뀌고, 제1유로(10)를 통해 유입되었던 작동유는 다시 제1유로(10)를 통해 배출되어 유압탱크(200)에 저장된다.At this time, when the internal pressure of the hydraulic cylinder 300 is increased by the piston 340, the direction of the solenoid valve 230 is changed, and the hydraulic fluid introduced through the first passage 10 is again returned through the first passage 10. Is discharged and stored in the hydraulic tank (200).

한편, 상기 제1에어펌프(400)와 제2에어펌프(500)의 공기는 에어펌프(400, 500)외측에 설치된 체크밸브(410, 510)에 의해 유입된다. 이때, 상기 체크밸브(410, 510)의 입구쪽에는 소결필터(810)가 설치결합되어 있어, 외부에서 먼지 등 이물질이 상기 에어펌프(400, 500)로 유입되지 않고 걸러진다.Meanwhile, the air of the first air pump 400 and the second air pump 500 is introduced by check valves 410 and 510 installed outside the air pumps 400 and 500. At this time, the sintered filter 810 is installed and coupled to the inlet side of the check valves 410 and 510, and foreign substances such as dust are filtered out without being introduced into the air pumps 400 and 500 from the outside.

이와 반대로 도 3에서와 같이 작동유가 제2유로(20)를 통해 상기 유압실린더(300)에 공급되면, 피스톤(340)은 제1에어펌프(400)방향으로 이동하고 제1에어펌프(400)내의 공기가 제5유로(50)를 통해 공기탱크(100)에 압축저장되고, 제2에어펌프(500)의 공기는 제4유로(40)를 통해 유압탱크(200)로 보내져 작동유를 냉각시킨다.On the contrary, when the working oil is supplied to the hydraulic cylinder 300 through the second passage 20 as shown in FIG. 3, the piston 340 moves in the direction of the first air pump 400 and the first air pump 400. The air inside is compressed and stored in the air tank 100 through the fifth flow path 50, and the air of the second air pump 500 is sent to the hydraulic tank 200 through the fourth flow path 40 to cool the working oil. .

따라서, 상기 유압실린더(300)의 피스톤(340)이 좌우로 이동할때마다 유압실린더(300) 양쪽에 설치된 제1에어펌프(400)와 제2에어펌프(500)가 펌프내의 공기를 압축하여 공기탱크(100)에 유입시키므로 보다 빠르게 압축공기를 저장할 수 있으며, 이때 발생하는 공기를 이용하여 유압탱크(200)에 저장된 작동유를 냉각시키는 장점이 있다.Therefore, whenever the piston 340 of the hydraulic cylinder 300 moves from side to side, the first air pump 400 and the second air pump 500 installed on both sides of the hydraulic cylinder 300 compress the air in the pump and Since the compressed air flows into the tank 100 more quickly, the compressed air can be stored, and there is an advantage of cooling the hydraulic oil stored in the hydraulic tank 200 using the air generated at this time.

이상에서 설명한 바와 같이 본 발명 에어콤프레셔에 따르면, 비교적 소음이적고 크기가 작은 에어실린더를 사용하여 압축공기를 공급하므로 산업용 공장뿐만 아니라 정숙을 요하는 병원과 같이 좁은 실내에도 설치할 수 있으며, 유압실린더 양측에 설치된 두개의 에어펌프에 의해 보다 빠르게 압축공기를 공급할 수 있어 작업능률을 향상시킬 수 있는 효과가 있다.As described above, according to the air compressor of the present invention, since the compressed air is supplied using an air cylinder having a relatively low noise and a small size, it can be installed not only in an industrial factory but also in a narrow room such as a hospital requiring quietness, and both sides of the hydraulic cylinder The two air pumps installed in the air supply air can be supplied more quickly, thereby improving work efficiency.

또한, 종래와 달리 펌프모터를 이용하여 바로 압축공기를 생성시키는 것이 아니라 작동유를 순환시켜 유압실린더동작시키고 이 유압실린더에 의해 왕복운동하는 에어펌프에 의해 압축공기가 생성되므로 작은 용량의 펌프모터를 사용할 수 있어 전류소모를 줄일 수 있는 효과가 있다.In addition, unlike the conventional method, a pump motor having a small capacity can be used because the compressed air is generated by an air pump reciprocating by operating the hydraulic cylinder and reciprocating the hydraulic fluid instead of generating compressed air directly using the pump motor. This can reduce the current consumption.
