본 고안은 일반가정에서 사용되고 있는 연탄 온수 보일러의 순환펌프 개량에 관한 것이다.The present invention relates to the improvement of the circulation pump of briquette hot water boilers used in general homes.
종래 사용되고 있는 순환펌프는 강제순환만을 목적으로 하는 소형 원심펌프로서 강제순환에 의한 수압의 상승으로 소음과 진동이 심하였고, 정전시 온수순환에 갑작스러운 중단으로 계속적인 연탄 화력의 가열로 인한 온수관내의 기압상승과 온수의 비등 팽창등으로 온수가 급수가 급수탱크내로 과다 유입되어 넘쳐 흐르는 결점이 있었다.Conventionally used circulating pump is a small centrifugal pump for the purpose of forced circulation only, and the noise and vibration are severe due to the increase of water pressure caused by forced circulation. As a result of the increase in the atmospheric pressure and the boiling expansion of the hot water, there was a defect that the hot water was excessively introduced into the water supply tank.
본 고안은 이러한 결점을 보완개량하여 소음과 진동이 없고, 정전시에는 온수가 외부로 넘처 흐르는 것을 미연에 방지할 수 있는 순환펌프를 안출한 것으로, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to improve the above-mentioned defects, there is no noise and vibration, and in the event of power failure, a circulating pump can be prevented in advance to prevent the hot water from overflowing to the outside.
반구형인 몸체(1)의 상부에 흡입구(2)를 형성하고, 중간양측에는 토출구(3)(3')를 직선상에 위치하도록 형성하며, 저면에는 하판(4)으로 밀폐하여 몸체(1)의 내부가 반구형의 와류실이 형성되게 하였다. 와류실내에는 날개(6)와 유통구(7)가 형성된 반구형 임펠러(5)를 수직으로 설치하여서된 것으로, 날개(6)는 임펠러(5)의 상단에서 하단으로 반구형선상을 따라 돌설케하고 유통구(7)는 임펠러(5)하단에 돌설된 날개(6)의 중간부에 요설하였다.The inlet port 2 is formed in the upper part of the hemispherical body 1, and the outlet port 3 and 3 'are formed in a straight line on both sides of the hemispherical body, and the body 1 is sealed by the lower plate 4 in the bottom surface. Hemispherical vortex chamber was formed inside of. In the vortex chamber, the hemispherical impeller (5) having the wing (6) and the distribution port (7) is installed vertically, and the wing (6) is inclined along the hemispherical line from the upper end to the lower end of the impeller (5). The sphere 7 is provided in the middle of the wing 6 protruding from the lower end of the impeller 5.
미설명부호 8은 모우터, 9는 모우터축, 10은 보일러, 11은 온수회수관, 12는 방열배관부, 13은 급수탱크이다.Reference numeral 8 is a motor, 9 is a motor shaft, 10 is a boiler, 11 is a hot water recovery pipe, 12 is a heat dissipation pipe, 13 is a water supply tank.
이와 같이 된 본 고안은 도면 제3도에 도시된 바와 같이 보일러와 온수배관회수측 사이에 설치되어 있다.The present invention as described above is installed between the boiler and the hot water pipe recovery side as shown in FIG.
본 고안의 작용 및 효과는 방열배관부(12)에서 회수되는 온수는 흡입구(2)로 유입되어 토출구(3)(3')를 통하여 보일러(10)내 가열배관으로 보내어져 재가열된 후 다시 방열배관부(12)로 유동한다. 임펠러(5)의 회전은 원심력에 의해 임펠러(5)의 상면에 국부공동(局部空洞)을 생성시키고 이 국부공동은 흡입구(2)측의 물을 와류실내로 계속 흡입되도록 유도한다. 날개(6)는 흡입된 와류실내의 물을 토출구(3)(3')로 송수되는 데 이때의 작용은 물이 고속으로 회전하는 날개(6)에 의해 원심력이 작용하며 압력과 속도에너지를 얻게된다. 임펠러(5) 하단의 유통구(7)는 임펠러(5)의 내부공간에서 발생하는 공동현상을 제거하는데 목적이 있다. 임펠러(5)내의 공동은 고속회전시, 모우터축(9)과 임펠러(5) 내면간의 공간에 위치한 물은 유동현상을 잃게 되어 정압(靜壓)이 저하하면서 공동을 발생시키는데 주위에 수개의 유통구(7)를 설정해주므로서 공동이 발생을 효과적으로 방지한다.The action and effect of the present invention is that the hot water recovered from the heat dissipation pipe portion 12 is introduced into the inlet (2) and sent to the heating pipe in the boiler 10 through the discharge port (3) (3 ') and reheated and then radiated again. It flows into the piping part 12. The rotation of the impeller 5 generates a local cavity on the upper surface of the impeller 5 by centrifugal force, and the local cavity induces the water on the suction port 2 side to be continuously sucked into the vortex chamber. The wing 6 receives water in the vortex chamber, which is sucked into the discharge port 3, 3 '. At this time, centrifugal force is acted on by the wing 6 in which the water rotates at high speed to obtain pressure and velocity energy. do. The distribution port 7 at the lower end of the impeller 5 is intended to remove cavitation occurring in the internal space of the impeller 5. When the cavity in the impeller 5 rotates at high speed, the water located in the space between the motor shaft 9 and the inner surface of the impeller 5 loses the flow phenomenon, and the static pressure decreases to generate the cavity. By setting the sphere (7), the cavity effectively prevents the occurrence.
정전시에 쉽게 일어나는 물의 넘침현상은 본 고안에서는 2개의 토출구(3)(3')를 통하여 미연에 방지할 수 있다.The overflow phenomenon of water easily occurring during power failure can be prevented through the two discharge ports 3 and 3 'in the present invention.
물의 온도가 상승할수록 대류현상도 활발해지는데 본 고안은 대류현상에 장애를 일으키는 요소를 갖지 않고 있다. 즉 토출구(3)(3')는 바이패스역활을 함으로써 대류가 원만하게 성립되게 한다.As the temperature of the water rises, convection is also active, but the present invention does not have an obstacle that causes the convection. In other words, the discharge ports 3 and 3 'play a bypass role to smoothly establish convection.
종래 원심펌프는 물이 임펠러내를 통과하여야 하고 흐름각도가 90로 꺽기게 되어 있어 대류를 억제하는 역할을 하고 있다.Conventional centrifugal pumps require water to pass through the impeller and have a flow angle of 90 It is supposed to break the convection to play a role.
따라서 본 고안은 정전시 과열에 의한 수압, 온도의 상승이 일어나드래도 넘침현상이 일어나지 않는다. 또 바이패스에 대한 커다란 장점은 장기간 사용하므로써 관내 축적된 스케일이 분리되어 배관내를 순환하드래도 임펠러를 파손시키지 않는다.Therefore, the present invention does not occur overflow even if the water pressure and temperature rise due to overheating during power failure. The big advantage of bypass is that long-term use separates the scale accumulated in the pipe and does not damage the impeller even if it circulates in the pipe.
종래의 원심펌프는 스케일이 임펠러내의 협로를 통과하면서 임펠러를 손상시키는 예가 허다하였다.Conventional centrifugal pumps are often examples of damaging the impeller as the scale passes through narrow passages in the impeller.
이상과 같이 본 고안은 강제순환을 목적으로 하는 종래의 순환펌프와는 달리 온수보일러 자체에서 생기는 대류현상을 보완하는 보조적 역할을 부가되어 운전시 소음과 진동이 없고 장기간 사용하드래도 쉽게 마모파손되는 등의 결점이 없는 유용한 고안인 것이다.As described above, the present invention, unlike the conventional circulation pump for the purpose of forced circulation, adds a supplementary role to complement the convection phenomenon generated by the hot water boiler itself, so that there is no noise and vibration during operation and wear is easily damaged even after long-term use. It is a useful design without the drawbacks.
