Description

온수순환펌프{CIRCULATING HOT WATER PUMP}Hot water circulation pump {CIRCULATING HOT WATER PUMP}

본 발명은 펌프에 관한 것으로, 특히 보일러나 온수매트 등에 사용되는 온수순환펌프의 개량에 관한 것이다. The present invention relates to a pump, and more particularly, to an improvement of a hot water circulation pump used in a boiler or a hot water mat.

온수순환펌프는 온실과 축사 등의 온수난방용의 순환펌프로서, 보일러 등의 가열기에서 가열시킨 온수를 난방호스와 같은 방열기로 보내고 이를 다시 가열기로 되돌려 받도록 하는 중요한 부품이다. The hot water circulation pump is a circulation pump for hot water heating in greenhouses and barns, and is an important part for sending hot water heated by a heater such as a boiler to a radiator such as a heating hose and returning it back to the heater.

온수순환펌프는 일반 가정이나 축사와 같은 곳의 난방기기에 채용되어 널리 사용될 뿐 아니라 온수매트용으로도 사용이 된다. 온수매트용의 온수순환펌프는 일반 가정용에 비해서 대체로 펌프용량이 적게 구현된다. The hot water circulation pump is widely used in heating devices such as homes or barns, and is also widely used for hot water mats. Hot water circulation pumps for hot water mats are generally implemented with less pump capacity than ordinary households.

기존 온수순환펌프는 외부의 구동모터로 임펠러를 회전시켜서 물을 순환시키는 바, 임펠라와 구동모터를 연결하는 구동축을 통해 누수되는 것을 막기 위해 메카니컬 씰을 사용한다. 하지만 구조상 메카니컬 씰로는 완벽한 누수차단이 힘들어 언제나 누수발생 소지를 안고 있다. 또한 기존 온수순환펌프는 임펠러 축이나 그 임펠러의 형상 변형 또는 모터와 임펠러를 연결하는 축베어링의 마모 등으로 소음 이 발생하고 더욱이 모터 자체의 소음이 상당한 문제가 있다. 온수매트용으로 사용하는 펌프의 소음을 다소 줄이기 위해 소용량 순환펌프를 사용하는 경우가 많은데 소용량의 순환펌프는 펌프 양정능력을 떨어뜨려 펌프의 고장을 종종 불러 일으키기도 한다.The existing hot water circulation pump circulates water by rotating the impeller with an external drive motor, and uses a mechanical seal to prevent leakage through the drive shaft connecting the impeller and the drive motor. However, due to the structural mechanical seal, it is difficult to block the perfect leak, so there is always a possibility of leakage. In addition, the existing hot water circulation pump generates noise due to the deformation of the impeller shaft or its impeller, or the wear of the shaft bearing connecting the motor and the impeller, and the noise of the motor itself is considerable. Small-capacity circulation pumps are often used to reduce the noise of pumps used for hot water mats. Small-capacity circulation pumps often cause pump failure due to poor pump lift.

따라서 본 발명의 목적은 소음이 최소화되고 누수 소지가 없는 온수순환펌프를 제공하는데 있다. Accordingly, an object of the present invention is to provide a hot water circulation pump which minimizes noise and is free of leakage.

본 발명의 다른 목적은 소음이 최소화되고 누수 소지가 없음과 동시에 구조가 간단하고 고장율도 적은 온수순환펌프를 제공하는데 있다. Another object of the present invention is to provide a hot water circulation pump which minimizes noise and has no leakage, and has a simple structure and a low failure rate.

상기한 목적을 달성하기 위한 본 발명은, 온수순환펌프에 있어서, 계자코일이 내장된 커버케이스내에 유입구 및 토출구를 가지며 캔 하우징이 포함된 캔본체를 삽입하고, 상기 캔 하우징내에는 샤프트를 갖는 펌핑회전체를 잠입하고 상기 샤프트가 내부 축지지부에 축지지되게 구성하되 상기 펌핑회전체내에는 원통부를 가로질러 양측 단면동심원으로 개통된 다수 유류통로들이 사선방향으로 형성되게 하고 상기 펌핑회전체가 상기 계자코일의 전류흐름에 의한 자계에 반응하여 회전되게 구성함을 특징으로 한다. The present invention for achieving the above object, in the hot water circulation pump, the can body having the inlet and discharge port in the cover case in which the field coil is embedded and the can housing is inserted, pumping having a shaft in the can housing The rotating body is immersed and the shaft is axially supported by the inner shaft support portion, but in the pumping rotating body, a plurality of oil passages are opened in diagonal direction across the cylindrical portion, and the pumping rotating body is formed in the field coil. Rotate in response to the magnetic field caused by the current flow of.

상기 축지지부는 캔하우징내 전후에 끼움설치되며 가속유도홈들이 동심배열되게 형성된 가속 유도체임을 특징으로 한다. The shaft support portion is installed in the front and rear of the can housing, characterized in that the acceleration derivatives are formed to be concentrically arranged acceleration induction grooves.

또 상기 펌핑회전체는 마그네틱분말이 포함된 내열합성수지 재질로 구성하거나 루프코일들로 된 전자석이 내열합성수지재질 본체에 매립형성하여 구성함을 특징으로 한다.In addition, the pumping rotating body is composed of a heat-resistant resin material containing a magnetic powder or an electromagnet made of loop coils is formed by embedding in the heat-resistant resin material body.

본 발명은 펌프가 물에 잠입되고 펌프구동이 간접 동력으로 전달받는 구조이므로 펌프구동에 따른 소음이 거의 없고 기존 외부모터와 내부 임펠러를 연결하는 축에 메카니컬 씰로 장착할 필요가 전혀 없으며 누수의 소지도 없게 된다. 또한 본 발명은 내부 임펠라 없이 펌핑회전체가 바로 유입수를 펌핑하므로 구조가 간단하고 고장률도 적은 장점도 있다. In the present invention, since the pump is submerged in water and the pump driving is transmitted by indirect power, there is almost no noise due to the pump driving, and there is no need to install it as a mechanical seal on the shaft connecting the existing external motor and the internal impeller. There will be no. In addition, the present invention has a merit that the pumping rotor immediately pumps the influent without an internal impeller, so the structure is simple and the failure rate is low.

본 발명의 온수순환펌프(2)는 다수의 계자코일(12)들이 내장된 커버케이 스(10)와, 캔하우징(14a)과 체결구(14b)로 된 캔 본체(14)와, 펌프역할과 회전체 역할을 동시에 하는 펌핑회전체(20), 펌핑회전체(20)의 샤프트(22)를 축지지하는 축지지부(24)(26)를 포함하여 구성한다. The hot water circulation pump 2 of the present invention includes a cover case 10 having a plurality of field coils 12 embedded therein, a can body 14 including a can housing 14a and a fastener 14b, and a pump role. And a shaft support part 24 and 26 for supporting the shaft 22 of the pumping rotor 20 and the pumping rotor 20 simultaneously acting as the rotor.

캔하우징(14a)의 일단에는 물과 같은 유체의 유입구(16)가 형성되고 캔하우징(14a)의 타단에는 체결을 위한 플랜지부가 형성된다. 캔하우징(14a)의 타단 플랜지부에는 유체의 토출구(18)를 갖는 체결구(14b)의 플랜지부가 면접한다. One end of the can housing 14a is formed with an inlet 16 of a fluid such as water, and a flange portion for fastening is formed at the other end of the can housing 14a. The flange portion of the fastener 14b having the discharge port 18 of the fluid is interviewed with the flange portion of the other end of the can housing 14a.

캔하우징(14a)의 내실에는 먼저 펌핑회전체(20)와 펌핑회전체(20)의 샤프트(22)를 축지지하는 축지지부(24)(26)가 잠입되게 하고 그 다음에 체결구(14b)의 플랜지부를 캔하우징(14a)의 타단 플랜지부에 면접시켜서 수밀용 패킹(15)이 개재된 상태로 볼트체결한다. Into the inner chamber of the can housing 14a, first, the pump support rotating body 20 and the shaft support parts 24 and 26 for axially supporting the shaft 22 of the pumping rotating body 20 are immersed, and then the fastener 14b. ), The flange portion of the can be interviewed with the other end flange portion of the can housing 14a and bolted with the watertight packing 15 interposed therebetween.

캔하우징(14a)과 체결구(14b)로 된 캔 본체(14)의 양측에 형성된 유입구(16)와 토출구(18)에는 난방호스가 각각 연결된다. Heating hoses are respectively connected to the inlet port 16 and the outlet port 18 formed on both sides of the can body 14 including the can housing 14a and the fastener 14b.

캔하우징(14a)의 원통외면에는 계자코일(12)이 내장된 커버케이스(10)가 설치되는 바 다수의 계자코일(12)은 캔하우징(14a)의 원통외면을 빙둘려 형성된다. 계자코일(12)은 전류의 흐름 방향에 따른 N,S자계를 발생하는 전자석이 된다. A cylindrical outer surface of the can housing 14a is provided with a cover case 10 in which the field coil 12 is embedded, and thus a plurality of field coils 12 are formed by surrounding the cylindrical outer surface of the can housing 14a. The field coil 12 becomes an electromagnet which generates N and S magnetic fields along the current flow direction.

캔 하우징(14a)의 내실에는 샤프트(22)를 갖는 펌핑회전체(20)가 잠입된다. 펌핑회전체(20)의 샤프트(22)는 가속유도체 역할을 하는 전후 축지지부(24)(26)에 그 양단이 축설치되며, 그 축지지부(24)(26)는 캔 하우징(14a)의 내실 양측 즉 유입구(16)측과 토출구(18)측에 끼워져서 고정된다. The pumping rotating body 20 which has the shaft 22 is enclosed in the inner chamber of the can housing 14a. Both ends of the shaft 22 of the pumping rotating body 20 are axially installed at the front and rear shaft supports 24 and 26 serving as acceleration inductors, and the shaft supports 24 and 26 are formed of the can housing 14a. It is fitted and fixed on both sides of the inner chamber, that is, the inlet 16 and the outlet 18.

샤프트(22)가 첨부 도면들에 도시된 일예와 같이 축지지부(24)(26)가 고정되 게 축설치되면(고정축이 됨), 원통형의 펌핑회전체(20)가 회전하기 위해서 펌핑회전체(20)의 축공에는 부시베어링(21)가 압삽되게 구성한다. 이때에는 샤프트(22)에 끼워진 펌핑회전체(20)의 부시베어링(21)이 미끄럼 회전운동을 하므로 펌핑회전체(20)가 회전을 하게된다. 다른 일예로 펌핑회전체(20)에 샤프트(22)가 바로 압삽 고정된다면(회전축이 됨), 펌핑회전체(20)와 샤프트(22)가 일체로 회전하게 되는데 이때에는 부시베어링(21)은 양측 축지지부(24)(26)의 축공에 각각 압삽되게 구성하여서 샤프트(22)가 고정된 부시베어링(21)내에서 미끄럼회전운동을 하게 한다. 상기 샤프트(22)의 재질은 내열성 윤활고분자소재가 바람직하며, 그 대표적 일예로는 피크(peek) 폴리머가 있다.When the shaft 22 is shaft-mounted 24 (26) is fixedly fixed (as a fixed shaft), as shown in the example shown in the accompanying drawings, the cylindrical pumping rotating body 20 is pumped to rotate The bush bearing 21 is configured to be pressed in the shaft hole of the whole 20. At this time, the bushing 21 of the pumping rotor 20 fitted to the shaft 22 performs a sliding rotational motion, so that the pumping rotor 20 rotates. As another example, if the shaft 22 is directly pushed and fixed to the pumping rotating body 20 (which becomes a rotating shaft), the pumping rotating body 20 and the shaft 22 are integrally rotated. In this case, the bushing bearing 21 is It is configured to be pushed into each of the shaft holes of the shaft support portions 24 and 26 so as to allow the shaft 22 to slide in the fixed bush bearing 21. The material of the shaft 22 is preferably a heat-resistant lubricating polymer material, and a representative example thereof is a peak polymer.

캔 하우징(14a)의 내실에 잠입된 펌핑회전체(20)는 캔하우징(14a)의 외면에 빙둘러 형성된 계자코일(12)들의 전류흐름에 의한 자계에 반응하여서 회전을 한다. The pumping rotary body 20 immersed in the inner chamber of the can housing 14a rotates in response to the magnetic field caused by the current flow of the field coils 12 formed on the outer surface of the can housing 14a.

상기 계자코일(12)들의 전류흐름에 의한 자계에 반응하기 위해서, 펌핑회전체(20)에는 N극과 S극이 교호적으로 배치된 영구자석이나 N극과 S극이 여기되는 전자석이 형성된다. In order to react to the magnetic field caused by the current flow of the field coils 12, the pumping rotor 20 is provided with a permanent magnet in which the N pole and the S pole are alternately arranged, or an electromagnet in which the N pole and the S pole are excited. .

펌핑회전체(20)에 영구자석이 형성되도록 하기 위해서 본 발명에서서는 펌핑회전체(20)를 마그네틱분말이 포함된 내열합성수지 재질을 이용하여 제조한다. 즉 마그네틱분말이 포함된 내열합성수지를 사출성형하여 펌핑회전체(20)의 각 존별로 영구자석들이 형성되게 한다. 다시 설명하면, N극과 S극의 마그네틱분말이 원주면을 따르는 존(zone)들에 교호적으로 분포되게 하여 N극과 S극이 교번하는 영구자석이 각 존에 형성되게 하는 것이다.In order to form a permanent magnet in the pumping rotor 20, in the present invention, the pumping rotor 20 is manufactured using a heat-resistant synthetic resin material containing magnetic powder. In other words, the injection molding of the heat-resistant synthetic resin containing the magnetic powder to form a permanent magnet for each zone of the pumping rotary body (20). In other words, the magnetic powders of the north pole and the south pole are alternately distributed in the zones along the circumferential surface, so that the permanent magnets alternate between the north pole and the south pole are formed in each zone.

또 펌핑회전체(20)에 전자석이 형성되도록 하기 위해서는 내열합성수지재질을 이용하여 사출성형하되 각 존마다 철심에 코일이 감고 그 코일을 폐루프로 연결하여서 된 루프코일을 각각 매립 형성하면 된다. In addition, in order to form an electromagnet on the pumping rotating body 20, injection molding is performed using a heat-resistant synthetic resin material, but a coil is wound around an iron core in each zone, and a loop coil formed by connecting the coils with a closed loop may be formed in each of the landfills.

본 발명에서는 펌핑회전체(20)가 계자코일(12)과 자계반응하여 상기와 같은 회전하는 동력전달 회전체가 될 뿐 아니라 펌프역할 즉 기존의 임펠라 역할도 동시에 한다. In the present invention, the pumping rotor 20 magnetically reacts with the field coil 12 to become a rotating power transmission rotor as described above, and also plays a role of a pump, that is, a conventional impeller.

펌프역할을 위해서 펌프회전체(20)에는 원통부를 가로질러 양측 단면동심원에까지 개통된 다수의 유류통로(30)들을 형성하되 각 유류통로(30)는 도 5에서와 같은 평단면 관점에서 사선방향으로 형성된다. 상기 유류통로(30)은 동일크기의 양측 단면동심원상에서 나선방향으로 형성되는 것이 가장 바람직하지만 성형하기가 어렵다.For the pump role, the pump rotating body 20 forms a plurality of oil passages 30 which are opened to both side cross-section concentric circles across the cylindrical portion, and each oil passage 30 is in a diagonal direction in terms of a flat cross section as shown in FIG. 5. Is formed. The oil passage 30 is most preferably formed in a spiral direction on both side concentric circles of the same size, but difficult to form.

그러므로 상기 유류통로(30)는 평단면 관점에서 사선방향으로 형성하는 것이 바람직하며, 토출구(18)에서 바라볼 때 시계방향(CW)으로 펌핑회전체(20)가 회전하는 것을 가정할 경우 유류통로(30)는 예컨대 도 6에서와 같이 시침 12시 30분 방향 유입지점에서 시침 12시방향 유출지점으로 된 사선방향으로 형성된다. Therefore, the oil passage 30 is preferably formed in an oblique direction in terms of a planar cross section, and when the pumping rotary body 20 rotates clockwise (CW) when viewed from the discharge port 18, the oil passage For example, 30 is formed in an oblique direction from an inflow point in the hour hand 12:30 direction as shown in FIG.

상기 유류통로(30)는 본 발명의 첨부 도면들에 도시된 일예와 같이 관통공 형태로 형성하는 것이 바람직하지만, 원주면에 홈이 드러나는 관통홈 형태로도 형성할 수 있음이 이 기술분야의 통상의 지식을 가진 자에게 자명하여진다. The oil passage 30 is preferably formed in the form of through-holes as shown in the accompanying drawings of the present invention, but can be formed in the form of through-holes in which grooves are exposed on the circumferential surface. Self-evident to those who have knowledge of

한편 펌핑회전체(20)를 축지지하는 양측단 축지지부(24)(26)에는 도 5의 평단면도에서 쉽게 볼 수 있듯이 펌핑회전체(20)의 유류통로(30)의 사선방향과는 반 대되는 사선방향으로 된 가속유도홈(28)들이 동심배열되게 형성된다. 상기 가속유도홈(28)은 작용과 반작용의 원리로 물과 같은 유체를 가속시켜주며, 도 7에서와 같이 유류통로(30)의 형성개수만큼이 축지지부(24)(26)에 형성된다. On the other hand, on both side shaft support parts 24 and 26 for axially supporting the pumping rotor 20, as shown in the plan view of FIG. 5, the oil passage 30 of the pumping rotor 20 is opposite to the diagonal direction of the oil passage 30. Accelerated induction grooves 28 in diagonal directions are formed to be concentrically arranged. The acceleration guide groove 28 accelerates a fluid such as water on the principle of action and reaction, and is formed in the shaft support portions 24 and 26 as much as the number of the oil passages 30 as shown in FIG.

상기한 구성에 의거하여 본 발명의 온수순환펌프(2)의 작동원리를 더욱 상세히 설명한다. Based on the above configuration, the operation principle of the hot water circulation pump 2 of the present invention will be described in more detail.

제어회로부(미도시됨)의 제어 하에 캔하우징(14a)의 원통외면에 빙둘러져 있는 다수의 계자코일(12)들에 전류가 흐르게 되면 N,S자계가 교번적으로 발생하면서 캔하우징(14a)에 잠입되어 축지지된 펌핑회전체(20)내의 각 존별 영구자석이나 전자석에 인력 또는 척력을 작용시켜 펌핑회전체(20)를 회전시키게 된다. 펌핑회전체(20)내 전자석은 교류모터와 유사한 구동 원리로 회전을 한다. Under the control of a control circuit unit (not shown), when current flows in a plurality of field coils 12 circumscribed on the cylindrical outer surface of the can housing 14a, the N and S magnetic fields alternately occur and the can housing 14a. The pumping rotary body 20 is rotated by applying attraction force or repulsive force to the permanent magnet or electromagnet for each zone in the pumping rotary body 20 immersed in and supported by the shaft. The electromagnet in the pumping rotor 20 rotates on a driving principle similar to that of an AC motor.

펌핑회전체(20)가 도 5 내지 도 7에 표기된 화살표의 시계방향(CW)으로 회전하게 되면 물과 같은 유체를 유입지점에서 유출지점으로 밀어내게 되므로 유입구측 축지지부(24)내 가속유도홈(28)들을 통해서 유체가 흡입되고 펌펑회전체(20)의 유류통로(30)의 초입부 시계방향의 내벽측을 비스듬하게 부딪히면서 자연스럽게 유입되고 펌핑회전체(20)에 작용하여 가속되게 하고 또 펌핑회전체(20)의 회전력에 의해서 사선방향으로 형성된 유류통로(30)의 유입지점에서 유출지점으로 밀려가게 된다. 펌핑회전체(20)의 유류통로(30)에서 빠져 나온 물과 같은 유체는 토출구측 축지지부(24)의 가속유도홈(28)에 반시계방향의 내벽측에 비스듬하게 부딪히면서 유류통로(30)와는 역사선방향으로 형성된 가속유도홈(28)의 통로를 부딪힘의 반작용으로 더욱 빨라져서 캔 본체(14)의 토출구(18)로 나가게 된다. When the pumping rotary body 20 rotates clockwise (CW) of the arrows shown in FIGS. The fluid is sucked through the 28 and hits the inner wall side clockwise of the entry portion of the oil passage 30 of the pumping rotor 20 at an angle so that the fluid is naturally introduced and acts on the pumping rotor 20 to be accelerated and pumped. By the rotational force of the rotating body 20 is pushed from the inflow point of the oil passage 30 formed in an oblique direction to the outflow point. Fluid such as water that has escaped from the oil passage 30 of the pumping rotor 20 hits the acceleration guide groove 28 of the discharge port side shaft support 24 at an angle to the inner wall side in the counterclockwise direction, and flows through the oil passage 30. The vortices are accelerated by the impact of the impact on the passage of the acceleration induction groove 28 formed in the inlet direction and exit to the discharge port 18 of the can body 14.

상기와 같은 본 발명의 온수순환펌프(2)는 펌프 즉 임펠라 역할을 하는 펌핑회전체(20)가 물에 잠입된 구조이므로 펌프구동에 따른 소음이 거의 없다. 또 펌핑하는 펌핑회전체(20)의 샤프트(22)가 캔 본체(14) 내부에 존재하므로 누수를 위한 별도의 메카니컬 씰을 장착할 필요도 없고 누수의 소지도 전혀 없다. Since the hot water circulation pump 2 of the present invention as described above has a structure in which the pump rotating body 20 serving as a pump, that is, an impeller, is immersed in water, there is almost no noise due to the pump driving. In addition, since the shaft 22 of the pumping rotating body 20 to be pumped exists in the can body 14, there is no need to install a separate mechanical seal for water leakage, and there is no leakage of water.

또 본 발명의 온수순환펌프(2)는 펌핑회전체(20)가 펌프(임펠라) 역할도 동시에 회전체 역할을 동시에 하므로 구조가 간단하고 고장도 별로 없게 된다. In addition, the hot water circulation pump (2) of the present invention, because the pumping rotating body 20 also serves as a pump (impeller) at the same time, the structure is simple and there is not much trouble.
