Description
본 발명은 롤러 펌프에 관한 것으로서, 더욱 상세하게는, 180도 방향으로 홈이 형성된 롤러와 역시 180도 방향으로 두 개의 임펠러가 장착된 롤러가 서로 맞물려 실린더내에서 회전펌핑함으로써, 펌핑과정중의 소음이 현저히 저감됨은 물론 운전정지시의 유체역류가 발생하지 않는 롤러 펌프에 관한 것이다.The present invention relates to a roller pump, and more particularly, a roller formed with a groove in a 180 degree direction and a roller equipped with two impellers in a 180 degree direction are engaged with each other and rotationally pumped in a cylinder, thereby making noise during the pumping process. Not only is this significantly reduced but also relates to a roller pump in which no fluid backflow occurs during shutdown.
일상생활중 사람들에게 특히 많은 스트레스를 주는 공해요소 가운데 소음공해가 차지하는 비중은 상당하다.Noise pollution occupies a significant portion of the pollutants that give people a lot of stress in their daily lives.
그 소음 발생원인으로서는 가정용 또는 산업용 펌프 등을 비롯하여 무수히 많다. 쾌적한 생활환경을 유지한다는 측면에서, 이들 소음발생원인으로부터의 소음을 저감시키기위한 연구가 실로 오랫동안 이어져온게 사실이다.There are numerous reasons for the noise, including household or industrial pumps. In terms of maintaining a comfortable living environment, it is true that research to reduce noise from these noise sources has been conducted for a long time.
베인 펌프, 피스톤 펌프, 기어 펌프, 스크류 펌프 또는 롤러 펌프 등으로 분류되는 상기 펌프들 역시 그 소음방지 대책이 다각적으로 강구되고 있다.These pumps, which are classified as vane pumps, piston pumps, gear pumps, screw pumps or roller pumps, have also been variously devised for preventing noise.
상기 롤러 펌프는 가동형 슬리브가 장착된 하나의 롤러가 실린더내에서 편심된 상태로 회전하게 된 구조다. 한편, 이들 롤러 펌프에는 역류방지 밸브가 별도로 구비되어 있어서 가동정지의 유체역류를 방지한다.The roller pump has a structure in which one roller equipped with a movable sleeve rotates in an eccentric state in a cylinder. On the other hand, these roller pumps are provided with a non-return valve separately to prevent fluid backflow of the stop operation.
그러나, 이러한 종래의 롤러 펌프에 따르면, 고속회전하는 롤러 자체의 편심으로 인해 진동 및 소음이 불가피한 근본적 문제점이 있었다.However, according to the conventional roller pump, there is a fundamental problem that vibration and noise are inevitable due to the eccentricity of the roller itself rotating at a high speed.
또한, 장기 사용할 때 상기 역류방지 밸브에 다량의 이물질이 끼어 밸브의 기능 저하 또는 고장을 초래하는 관계로, 잦은 점검 및 수리가 불가피 했다.In addition, since a large amount of foreign matter is caught in the non-return valve in the long-term use, resulting in a deterioration or failure of the valve, frequent inspection and repair was inevitable.
본 발명은 이러한 종래의 문제점을 감안하여 안출한 것으로서, 본 발명의 목적은, 180도 방향으로 두 개의 홈이 형성된 롤러와 역시 180도 방향으로 두 개의 임펠러가 장착된 롤러가 서로 맞물려 원활히 회전함으로써, 소음이 현저히 감소됨과 아울러 따로 역류방지 밸브가 필요없는 롤러 펌프를 제공하는 데 있다.The present invention has been made in view of such a conventional problem, the object of the present invention is that the roller formed with two grooves in the 180 degree direction and the roller equipped with two impellers in the 180 degree direction also mesh with each other to rotate smoothly, The present invention provides a roller pump that significantly reduces noise and eliminates the need for a non-return valve.

상기 목적을 달성하기 위한 본 발명의 롤러 펌프는, 180도 방향으로 두 개의 홈이 형성된 롤러와, 역시 180도 방향으로 두 개의 임펠러가 장착된 롤러와, 이들 두 개의 롤러가 내장된 실린더와, 롤러축에 각각 장착되어 1:1의 회전비율로 서로 맞물려 회전하는 중간기어와, 임펠러 장착 롤러축 하단부에 장착되어 구동부의 회전을 감속 전달하는 감속기어를 포함하여 구성된다. 즉, 상기 두 개 롤러의 홈 또는 임펠러가 서로 맞물려 회전하면서 흡입구측으로 부터의 유체를 토출구측으로 압송하는 특징이 있다.The roller pump of the present invention for achieving the above object is a roller having two grooves formed in the 180 degree direction, a roller equipped with two impellers also in the 180 degree direction, a cylinder with these two rollers, Intermediate gears mounted on the shafts and engaged with each other at a rotational ratio of 1: 1 and rotated, and reduction gears mounted on the lower end of the impeller-mounted roller shaft to reduce and transmit the rotation of the drive unit. That is, the grooves or impellers of the two rollers are engaged with each other to rotate and pressurize the fluid from the suction port side to the discharge port side.
또한, 상기 홈 및 그에 삽입된 임펠러가 칸막이 역할을 충실이 수행하기 때문에 별도의 역류방지 밸브는 포함되지 않는다.In addition, since the groove and the impeller inserted therein faithfully serve as a partition, a separate non-return valve is not included.
우선, 제1도는 본 발명 실시예의 롤러 펌프에 있어서, 휠드코일(10)과 아마추어(9)가 구성된 하부와, 아마추어(9)의 축기어(27)에 맞물리는 감속기어(8)와, 임펠러 장착 롤러축(4)에 장착된 중간기어(6)와 1:1의 회전비율로 맞물려 회전하는 홈이 형성된 롤러축(5)의 중간기어(7)로 구성된 중간부와, 각각의 중간기어(6,7)에 의해 회전되며 180도 방향에 두 개의 홈이 형성된 롤러(2)와 역시 180도 방향으로 두 개의 임펠러(13)가 장착된 롤러(3)가 서로 맞물려 회전 펌핑하는 실린더(11)실과, 실린더(11)상부에 결합된 상부 실린더 덮개(12)로 구성된다.First, in the roller pump of the embodiment of the present invention, the lower portion of the wheeled coil 10 and the armature 9, the reduction gear 8 meshing with the shaft gear 27 of the armature 9, and the impeller Intermediate portion consisting of the intermediate gear (7) of the roller shaft (5) in which the groove is rotated in engagement with the intermediate gear (6) mounted on the mounting roller shaft (4) at a rotational ratio of 1: 1, and each intermediate gear ( The cylinder 11 rotated by 6 and 7 and the roller 11 having two grooves formed in the 180 degree direction and the roller 3 equipped with the two impellers 13 in the 180 degree direction are engaged with each other and rotationally pumped. It consists of a seal and an upper cylinder cover 12 coupled to the cylinder 11 upper part.
제2도는 상기 제1도의 A-A선 단면도 나타낸 두 개의 홈이 형성된 롤러(2)와 두 개의 임펠러(13)를 장착한 롤러(3)는 홈(14)에 임펠러(13)가 맞물려 칸막이 작용에 의해 흡입구(15) 측면과 토출구(16) 측면을 차단시키므로 유체의 유동을 막으며, 롤러의 회전에 따라 흡입구축(15)에서 흡입되어 임펠러(13)를 따라 펌프실(20)에서 토출구(16)로 강압 토출된다. 또한, 홈(14)안에 임펠러(13)가 맞물림에 따라 흡입구쪽(15)과 토출구(16)쪽이 칸막이 작용과, 역시 두 개의 롤러(2,3)면도 맞대응됨에 따라 칸막이 작용으로 회전 펌핑된다.FIG. 2 shows the roller 2 having two grooves and the two impellers 13 mounted thereon as shown in the cross-sectional view taken along the line AA of FIG. 1. The impeller 13 is engaged with the grooves 14 by the partitioning action. It blocks the side of the suction port 15 and the side of the discharge port 16 to prevent the flow of the fluid, and is sucked by the suction inlet shaft 15 in accordance with the rotation of the roller to the discharge port 16 from the pump chamber 20 along the impeller 13 The pressure is discharged. In addition, as the impeller 13 is engaged in the groove 14, the suction port side 15 and the discharge port 16 side are partitioned and the two rollers 2 and 3 are also faced with rotational pumps. .
제3도는 기체나 점성이 작은 유체의 펌핑시, 기밀이 요구되므로 실린더(16)벽면과 상, 하부 3면에 대응하는 합성고무재질이나 금속재질의 슬리브(21)가 임펠러 케이스(23)안에 판 스프링(22)에 고정되어 밀착되어 회전한다.FIG. 3 shows that airtightness is required when pumping gas or small viscous fluid, so that a sleeve 21 made of synthetic rubber or metal corresponding to the wall, upper and lower surfaces of the cylinder 16 is plated in the impeller case 23. It is fixed to the spring 22, it is in close contact and rotates.
상기와 같이 구성된 롤러 펌프는, 기체 또는 비점성 유체의 펌핑시에도, 두 개 임펠러(13)가 상기 판 스프링(22)의 탄발력을 받아 실린더 벽면 등의 관련 접촉면에 강하게 밀착됨으로써 작동중 기밀이 확실히 유지된다.In the roller pump configured as described above, even when the gas or non-viscous fluid is pumped, the two impellers 13 are firmly adhered to the related contact surfaces such as the cylinder walls by receiving the elastic force of the leaf spring 22 so that the airtight during operation It is certainly maintained.
이상 설명한 바와같이, 본 발명의 롤러 펌프는 홈 또는 임펠러가 형성 또는 장착된 두 개의 롤러가 서로 맞물려 균형 있게 회전함에 따라 가동중 소음이 현저히 감소함과 아울러 별도의 역류방지밸브를 필요로 하지 않는 효과가 있으므로 펌프 산업상 매우 유용한 발명인 것이다.As described above, the roller pump of the present invention has the effect of significantly reducing noise during operation and requiring a separate non-return valve as the two rollers having grooves or impellers formed or mounted are engaged with each other in a balanced manner. This is a very useful invention in the pump industry.
