Description
제 1 도는 본 고안의 종단면도.1 is a longitudinal sectional view of the present invention.
제 2 도는 본 고안 임펠러의 사시도.2 is a perspective view of the present invention impeller.
제 3 도는 본 고안의 횡단면도.3 is a cross-sectional view of the present invention.
본 고안은 양수기를 형성함에 있어서 양수기 본체의 내측벽과 임펠러의 외측면이 서로 밀착 회전되도록 임펠러를 삽설하되 임펠러의 회전익체 끝단을 끝단의 단면적이 넓게 회전 진행방향으로 만곡요홈부를 형성시키므로서 통상의 양수기에 비하여 배출압력을 높일 수 있게 한 양수기에 관한 것이다.The present invention is to insert the impeller so that the inner wall of the pump body and the outer surface of the impeller in close contact with each other in forming the pump, the end of the rotor blades of the impeller to form a curved groove in the direction of rotation progress to a wider cross-sectional direction of the end The present invention relates to a water pump that enables to increase the discharge pressure compared to the water pump.
종래의 양수기로서는 많은 종류가 개발되고 사용되고 있으나 이들의 배출압력은 거의 일정하게 한정되어 있으므로 고지대의 양수에는 적합치를 못하였다. 또한 조금 발전된 양수장치로서는 양수기 본체 내에 터어빈 펌프와 벌유우트 펌프를 일체로 장치하여 양정이 높을 때에는 터어빈 펌프를 사용하고 양정이 낮을 때에는 벌유우트 펌프를 사용할 수 있도록 한 양수장치가 있으나 이것 역시 한정된 배출압력 뿐이고 양정의 높고 낮음에 대하여 사용시마다 터어빈 펌프와 벌유우트 펌프를 선택장치하여야 하는 번거로움이 있었다.Many kinds of conventional water pumps have been developed and used, but their discharge pressures are almost constant, which is not suitable for pumping highlands. In addition, a slightly advanced pumping device includes a turbine pump and a bee milk pump in the body of the pump to use a turbine pump when the head is high and to use a bee milk pump when the head is low, but this is also limited. With only the discharge pressure and high and low head, there was a need to select a turbine pump and a beemilk pump each time it was used.
이외에, 일본국 특허공보에 게재된 공번 소 51-제39683호 "펌프용 우근차"가 알려진 바 있으나 이는 물 통로부에 단면적의 변화가 없이 요철부를 갖는 우근부를 형성하여서 된 것이므로 비교적 양수효율은 양호하지만 물 통로부내의 압력에 변동이 거의 없어 전술한 바와 같은 고지대의 양정을 도모하기에는 매우 어렵고 또, 양수시마다 물을 채워줘야 하는 등의 번거로움이 있었다.In addition, Japanese Patent Application Publication No. 51-399683 "Right Rope for Pumps" is known, but this is because it forms a right root portion having an uneven portion without changing the cross-sectional area of the water passage, so the pumping efficiency is relatively good. However, there is little change in the pressure in the water passage, so it is very difficult to plan the elevation of the highlands as described above, and there is the trouble of having to fill the water every time the pump is taken.
본 고안은 이와같은 점을 감안한 것으로 통상 사용되고 있는 터어빈 펌프를 개량하여 종래의 양수기에 비해 배출압력이 배가 하도록 하여 고지대의 양수에 적합토록 고안한 것으로서 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention was made in view of such a point, and is designed to be suitable for pumping highlands by doubling the discharge pressure compared to conventional water pumps by improving a turbine pump that is commonly used.
펌프 본체(1) 내에 공지의 임펠러(3)를 장설하되 끝단을 회전방향으로 만곡요홈부(R)를 형성하여 끝단의 면적(a)을 넓게 한 회전익체(2)를 수개 연설하여 임펠러(3)를 형성하고 이를 회전축(6)과 너트(10)로서 연설하되 본체의 내벽(1')과 임펠러(3)의 외측면(3')이 서로 밀착 회전되게 장설하는 한편 수실(4)에는 역지변(5)을 부착하여서 된 것이다.A well-known impeller (3) is installed in the pump main body (1), but the end of the curved groove portion (R) is formed in the rotational direction so that several rotor blades (2) having a large area (a) of the tip are extended to impeller (3). ) And speak as a rotating shaft (6) and nut (10), while the inner wall (1 ') of the main body and the outer surface (3') of the impeller (3) is installed in close contact with each other while the counter (4) It was made by attaching the ground (5).
이상과 같은 본 고안은 임펠러(3)를 회전시켜 양수를 꾀할 경우 임펠러의 회전익체(2)와 회전익체 사이에 충만된 물은 원심력에 의하여 양수기 본체(1)의 내벽(1')으로 확산되는데 이때 임펠러(3)는 본체(1) 내벽(1')에 밀착되어 회전하므로 물은 내벽(1')에 부딪히면서 밖으로 나가려는 힘은 더욱 가중됨과 동시 배출통로 입구(8)에 회전 도달하면 힘차게 임펠러(3) 내부를 이탈하여 배출관(7)으로 분출되는 것이다. 이때 회전익체(2)의 끝단 만곡요홈부(R)는 임펠러(3)의 내부를 이탈하는 물을 다시 한번 채워주어 가일층 배출압력을 높일 수 있고 끝단의 단면적이 넓으므로서 후진하려는 물의 압력을 받혀주므로서 배출압력을 더욱 높일 수 있는 것이다.In the present invention as described above, when the impeller 3 rotates to pump water, the water filled between the rotor blade 2 and the rotor blade of the impeller is diffused into the inner wall 1 'of the pump body 1 by centrifugal force. At this time, since the impeller 3 rotates in close contact with the inner wall 1 'of the main body 1, the water impinges on the inner wall 1' and further increases the force to go out. (3) It is ejected to the discharge pipe (7) by leaving the inside. At this time, the end curved groove portion (R) of the rotor blade (2) can fill the water leaving the interior of the impeller (3) once again to increase the discharge pressure even further, and the end surface area of the end to receive the pressure of the water to reverse It is possible to increase the discharge pressure further by giving.
또한 역지변(5)은 송수가 중단되면 즉시 흡입구(9)를 차단하므로서 수실(4)에는 항시 물이 충만되어 있기 때문에 다시 양수작업을 시작할시는 수실(4)에 물을 주입하지 않고 즉시 양수작업을 할 수 있는 것이다.In addition, since the reverse valve 5 shuts off the water inlet 9 immediately when the water supply is stopped, the water chamber 4 is always filled with water, and thus immediately pumps water without injecting water into the water chamber 4 when starting the pumping work again. You can work.
이상과 같이 본 고안은 배출압력을 높여주어 농촌 등지에서 고지대에 양수하고자 할 때 2~3대로서 계단식 양수를 하므로서 발생하는 인력의 낭비 그리고 경제적인 낭비는 물론 작업시간도 단축할 수 있게 한 실용적인 고안인 것이다.As described above, the present invention is a practical design that can reduce work time and economical waste as well as economical waste caused by cascading two to three units when raising the discharge pressure to pump up to highlands in rural areas. It is
