본 발명은 축류펌프형태의 수중프로펠러펌프를 토출관 내부에 시공함에 있어서, 펌프의 초기 작동시 내부 프로펠러의 가동에 의한 펌프케이싱의 역회전현상을 방지하고 토출관 펌프정 사이의 기밀이 유지될 수 있도록 한 설치구조에 관한 것이다.According to the present invention, when the submersible propeller pump in the form of an axial flow pump is installed inside the discharge pipe, it is possible to prevent the reverse rotation of the pump casing caused by the operation of the internal propeller during the initial operation of the pump and to maintain airtightness between the discharge pipe pump wells. It is about the installation structure so that.

일반적으로 종래의 축류펌프는 구동부의 밀봉이 어려운 관계로 그 구조가 회전프로펠러와 중심의 구동축 일부가 펌프실 내부에 위치하고 구동부로서 구동수단인 구동모터와 구동축의 나머지 일부는 별도로 위치하도록 설계되어 상기 펌프실은 수중에 설치하고 구동부는 수면상부의 타측에 설치하게 되어있다. 또한 펌프 케이싱의 경우 외측에 통수관을 관통설치하여 회전프로펠러의 가동에 의하여 펌핑이 이루어지면 통수관을 통하여 물을 급송할 수 있게 되어있다.In general, the conventional axial pump is difficult to seal the drive unit, the structure is designed so that the rotating propeller and the center drive shaft portion is located inside the pump chamber and the drive motor which is a driving means as the drive unit and the other part of the drive shaft are located separately. It is installed underwater and the driving part is installed on the other side of the upper surface. In addition, in the case of the pump casing is installed through the water supply pipe on the outside when the pumping is made by the operation of the rotary propeller it is possible to feed water through the water supply pipe.

이러한 종래의 경우에는 회전프로펠러의 작동시 펌프케이싱의 역회전현상이 발생될 염려가 거의 없으나 구동부가 일체로 형성되어 있는 수중프로펠러펌프를 토출관 내부로서 수중에 펌프전체를 설치하는 경우엔 펌프케이싱과 토출관을 상호 고정하지 아니하면, 프로펠러의 초기회전시 프로펠러의 회전방향과 반대방향으로 펌프케이싱이 역회전하게 되는 문제가 발생된다.In this conventional case, there is little concern that the reverse rotation of the pump casing may occur during the operation of the rotating propeller, but the pump casing and the pump casing may be used in the case of installing the underwater propeller pump having the driving unit integrally inside the discharge pipe. If the discharge pipes are not fixed to each other, a problem arises in that the pump casing is reversely rotated in the direction opposite to the rotation direction of the propeller during the initial rotation of the propeller.

물론 이 경우에 펌프케이싱과 토출관을 고정스크류와 같은 취부수단에 의하여 상호고정할수도 있겠으나 이와같이 고정하는 경우엔 이를 일일이 분해 결합해야하므로 펌프의 고정설치 및 분해가 어렵고 따라서 검사나 수리가 어려운 문제가 뒤따르게 된다.Of course, in this case, the pump casing and the discharge pipe may be fixed to each other by means of mounting means such as fixing screws, but in this case, fixing and disassembling the pump is difficult, and thus inspection or repair is difficult. Will follow.

또한 토출관과 펌프케이싱 사이엔 밀봉구조나 채택되어야만 하는데 실제로 펌프케이싱과 토출관을 단순한 면접촉이 이루어지도록 하는 경우 펌프의 가동시에 프로펠러의 양수가 이루어지면서 펌프정과 펌프케이싱 사이에서 기밀이 유지되지 않아 토출관 내부로 양수된 물중 그 일부가 다시 펌프정으로 유출되게 되고 결국 펌프효율의 저하를 가져오는 요인이 되고 있다.In addition, a sealing structure must be adopted between the discharge tube and the pump casing. In fact, when the pump casing and the discharge tube are simply in contact with each other, the propeller is pumped up during the operation of the pump and airtightness is maintained between the pump well and the pump casing. As a result, some of the water pumped into the discharge pipe is discharged back to the pump well, which is a factor that leads to a decrease in the pump efficiency.

본 발명은 이와같은 종래의 문제점을 해소하고자 연구 개발된 것으로서, 펌프케이싱의 외부대향측엔 회전 방지구를 설치하고 저면의 패킹홈에 패킹을 설칠하여 토출관의 저면에 플랜지형태의 시이트부를 마련하고 토출관의 내주면에 정지보강편을 용착고정하여 회전방지구는 보강편에 걸려 회전이 방지되고 패킹은 시이트부에 기밀 밀착되는 설치구조를 제공하여 펌프를 토출관의 상부로부터 끼워 넣어 사이트부에 안착시키면 그대로 설치가 완료될 수 있으므로 설치 및 분해가 용이하고 검사 및 수리가 용이하며, 펌프케이싱과 펌프정 사이에 기밀유지가 이루어져 펌프의 가동시에 양수된 물이 누출될 염려가 없으며, 이에 따라 펌프효율을 향상시킬 수 있도록 하는데 그 목적이 있다.The present invention has been researched and developed in order to solve such a conventional problem, by installing a rotation prevention port on the outer side of the pump casing and installing the packing in the bottom packing groove to provide a flange-like sheet on the bottom of the discharge pipe The stop reinforcing piece is welded and fixed on the inner circumferential surface of the discharge pipe so that the rotation preventing device is caught by the reinforcing piece to prevent rotation and the packing is airtightly adhered to the sheet part. As the installation can be completed as it is, installation and disassembly is easy, inspection and repair is easy, and there is no fear of leaking pumped water when the pump is running due to the airtightness between the pump casing and the pump well. The aim is to improve the

이때, 펌프(1)를 작동시키는 경우 펌프내부의 프로펠러가 회전하여 펌프정(7)으로부터 인접수로(8)로 물을 양수시키게되면 이에 따라 펌프케이싱(1a)이 역회전하려고 하나 펌프케이싱(1a)의 양측에 설치된 회전방지구(2)의 스토퍼(30)가 토출구본체(4)에 설치된 정지보강편(6)에 걸려 역회전이 방지되게 된다.At this time, when the pump 1 is operated, the propeller inside the pump rotates to pump water from the pump well 7 to the adjacent waterway 8.
