본 발명은 수중펌프에 관한 것으로서, 더욱 상세하게는 이물질(헝겁, 장갑, 끈, 음식물 쓰레기)등이 함유된 오수 및 하수를 양수하는 경우에 수중펌프의 유입구에서 이물질등을 효과적으로 절단하여 수중펌프의 임펠러 베인에 걸리지 않도록 함으로써, 이물질등이 함유된 오수 및 하수의 양수도 원활히 이루어지는 이물질 절단장치가 구비된 수중펌프에 관한 것이다.The present invention relates to an underwater pump, and more particularly, in the case of pumping sewage and sewage containing foreign substances (clothes, gloves, strings, food waste) and the like, the foreign substances are effectively cut at the inlet of the underwater pump. The present invention relates to a submersible pump equipped with a foreign material cutting device that smoothly pumps sewage and sewage containing foreign matters by preventing the impeller vanes from being caught.

일반적으로 수중펌프는 도 1에서 도시된 바와 같이 전동 모터부(100)와 그 아래의 위터 챔버(200)와, 그 아래의 임펠러 케이스(300)로 이루어진다.In general, the submersible pump is composed of the electric motor unit 100, the wiper chamber 200 below, and the impeller case 300 below.

상기 전동 모터부(100)는 하우징(110)의 내부에 마련된 고정자(120)와, 그 고정자(120)의 중앙에서 모터축(140)에 축착된 채 회전하는 회전자(130)와, 상기 모터축(140)을 지지하기 위한 상,하 베어링(150a,210a)을 포함하며, 이때의 상측 베어링(150a)은 모터캡(150)에 설치되고, 하측 베어링(210a)은 다음의 워터 챔버(200)를 구성하는 챔버 프레임(210)상에 설치된다.The electric motor unit 100 includes a stator 120 provided inside the housing 110, a rotor 130 rotating while being fixed to the motor shaft 140 at the center of the stator 120, and the motor. Up and down bearings (150a, 210a) for supporting the shaft 140, wherein the upper bearing 150a is installed in the motor cap 150, the lower bearing (210a) is the next water chamber 200 It is installed on the chamber frame 210 constituting the).

상기 모터축(140)은 챔버 프레임(20)을 지나서 워터 챔버(200)를 관통한 후, 그 아래의 임펠러 케이스(300) 내로 노출되어 임펠러(400)를 체결할 수 있게 된다.The motor shaft 140 passes through the water chamber 200 after passing through the chamber frame 20, and then is exposed to the impeller case 300 below the fastener 400 to fasten the impeller 400.

그리고 상기 임펠러 케이스(300)는 그 내부에서 모터축(140)의 끝단에 축착된 임펠러(400)와 상기 임펠러 케이스(300)를 받치는 베이스부재(310)로 이루어지고, 상기한 임펠러 케이스(300)의 저면에는 유입구(320), 측면에는 배출구(330)가 각각 구비된다.And the impeller case 300 is composed of an impeller 400 and the base member 310 that supports the impeller case 300 is fixed to the end of the motor shaft 140 therein, the impeller case 300 The bottom of the inlet 320, the side is provided with an outlet 330, respectively.

이때, 상기한 워터 챔버(200)의 속으로 관통하는 모터축(140)에는 모터축(140)이 회전하는 상태에서도 기밀이 유지되도록 메카니칼 씰(500)이 구비되고, 임펠러(400)가 축착되는 쪽으로는 오일 씰(350)이 구비된다.At this time, the motor shaft 140 penetrating into the water chamber 200 is provided with a mechanical seal 500 to maintain airtightness even when the motor shaft 140 rotates, and the impeller 400 is condensed. Towards the side the oil seal 350 is provided.

따라서, 모터캡(150)속으로 연결된 케이블을 따라 전원이 공급되면 고정자(120)와 회전자(130)사이에 발생하는 전자기력으로써 회전자(130)가 기동을 하게 되면, 그 기동력은 동축인 모터축(140)상에 연결된 임펠러(400)를 회전시키므로 임펠러 케이스(300)의 유입구(320)로부터 배출구(330)로 유체를 펌핑을 할 수 있게 된다.Therefore, when power is supplied along a cable connected to the motor cap 150, when the rotor 130 is started by the electromagnetic force generated between the stator 120 and the rotor 130, the starting force is a coaxial motor. Since the impeller 400 is connected to the shaft 140, the fluid can be pumped from the inlet 320 to the outlet 330 of the impeller case 300.

그러나 펌핑되는 유체가 이물질(헝겁, 장갑, 끈, 음식물 쓰레기)이 함유된 오수 및 하수인 경우에는 이물질등에 의해 임펠러의 베인에 걸려 펌핑을 할 수 없게 되고, 펌핑이 되었다 할지라도 이물질이 토출배관에 설치되어 있는 밸브등에 끼 게 됨으로써 펌프의 토출작용을 원활하지 못하게 되는 문제점이 있었다.However, if the fluid to be pumped is sewage and sewage containing foreign matter (clothes, gloves, strings, food waste), it is impossible to pump due to the foreign matter, and the pump cannot be pumped. There was a problem that the discharge action of the pump is not smooth by being caught in the valve.

이러한 임펠러의 걸림현상 및 배관의 막힘 현상이 유체에 함유된 이물질에 의한 것으로 종래의 펌프에서는 임펠러 입구측에 메쉬가 작은 스트레나 및 임펠러의 통과면적을 크게하여 사용하였으나 이물질의 농도에 따른 막힘 현상이 발생되어 사용상에 많은 문제점이 야기되었다.The jamming phenomenon of the impeller and the blockage of the pipe are caused by the foreign matter contained in the fluid. In the conventional pump, the passage area of the strainer and the impeller with the small mesh is increased at the inlet side of the impeller, but the clogging phenomenon occurs according to the concentration of the foreign matter. This has caused many problems in use.

따라서, 본 발명은 상기의 제반 문제점을 해결하기 위해 창안된 것으로, 본 발명의 목적은 수중펌프의 유입구측에 펌핑할 오수 및 하수에 포함되어 있는 이물질등을 절단하여 이물질등이 임펠러의 베인에 걸리지 않도록 함으로써, 원활한 양수가 이루어지게 하는데 있다.Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to cut foreign substances contained in the sewage and sewage to be pumped to the inlet side of the submersible pump, so that foreign substances are caught on the vane of the impeller. By doing so, smooth pumping is achieved.

또, 오수 및 하수에 포함된 이물질의 절단작업이 다수번에 걸져 이루어지게 되므로 이물질등을 보다 작고 정확하게 절단작업이 이루어져 수중펌프의 양수기능을 향상시키고 수중펌프의 수명을 연장시킬 수 있도록 하는데 있다.In addition, since the cutting work of the foreign matter contained in the sewage and sewage is made a plurality of times, the foreign matters are cut smaller and more accurately, so that the pumping function of the underwater pump can be improved and the life of the underwater pump can be extended.
