본 고안은 지하수속에 설치하여 지하수를 펌핑하는 수중펌프용 수분검출기를 내장한 수중모우터에 관한 것으로서, 본 출원인이 이미 취득한 실용신안등록 제44943호의 수중모우터를 더욱 개량하여 톱케이스의 회전부에 조립되어있는 회전씰이 마모되어 지하수속에 함유되어있는 미세한 모래입자가 수중 모우터내부에 유입됨으로 인하여 누전, 합선등의 고장발생과 베어링의 급속한 마모를 방지하기 위하여 톱케이스의 내부모우터축에 물을 흡수하고, 모래를 걸러내는 필터(FILTER)를 겸한 수분검출기를 고정하여 모래를 필터에 걸려지게하여 모우터내부로 유입되는 것을 방지함으로서 베어링 등 내부의 부품을 보호하고, 물은 필터에 흡수되게 하여 이를 지상에 설치된 전기콘트롤박스에 전기적 저항으로 측정될 수 있도록 하고, 일정치의 저항값이 되었을 때 수종모우터가 자동으로 정지되고 경보가 울리게하여 이의 원인이 된 회전씰을 적기에 교체시킬 수 있도록 한 것인데, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention relates to an underwater motor incorporating a water detector for a submersible pump installed in an underground water pump to pump underground water. As the rotary seal is worn and fine sand particles contained in the groundwater flow into the underwater motor, water is applied to the internal motor shaft of the top case to prevent the occurrence of short circuit, short circuit, etc. and the rapid wear of the bearing. It absorbs and fixes the water detector, which also functions as a filter that filters sand, thereby preventing sand from getting caught in the filter to protect the internal parts such as bearings, and water is absorbed by the filter. This can be measured by electrical resistance in the electric control box installed on the ground, and the resistance value is Geotinde be a so Sires emitter can be automatically stopped and an alarm is sounded to replace the small rotation seal the cause thereof, the will be described in detail by the accompanying drawings it follows when the.
코일(3)및 로우터(4)가 설치된 스테이터하우징(2)의 윗쪽에는 모우터축(1) 주위에 영구자석(10A), 베어링(7A)(7B)및 회전씰(9A)의 회전씰카버(9)를 개재시켜 일정한 간격으로 방열핀(5A)을 형성한 톱케이스(5)를 고정하고, 아랫쪽에는 영구자석(10B)및 베어링(8A)(8B)을 개재시켜 여러개의 방열핀(6A)을 형성한 앤드케이스(6)를 고정하여서 된 공지의 수중모우터에 있어서, 톱케이스(5)의 내부에는 절연몸체(11A), 전극판(11B), 필터(11C)및 임펠러(11D)로 된 수분검출기(11)를 고정하여 전극판(11B)은 전기콘트롤박스(13)에 연결하여 설정된 저항치에 도달하면 자동적으로 정지됨과 동시에 경보가 울리도록 한 것이다.On the upper side of the stator housing 2, in which the coil 3 and the rotor 4 are installed, the rotary seal cover of the permanent magnet 10A, the bearings 7A, 7B and the rotating seal 9A around the motor shaft 1 9) The top case 5 having the heat dissipation fins 5A formed thereon is fixed at regular intervals, and a plurality of heat dissipation fins 6A is formed at the bottom through the permanent magnet 10B and the bearings 8A and 8B. In a known submersible motor in which an end case 6 is fixed, the inside of the top case 5 includes an insulating body 11A, an electrode plate 11B, a filter 11C, and an impeller 11D. By fixing the detector 11, the electrode plate 11B is connected to the electric control box 13 to automatically stop when the set resistance value is reached and at the same time an alarm sounds.
미설명 부호 12는 불활성가스충전용플러그이다.Reference numeral 12 is an inert gas filling plug.
이와 같이 된 본 고안은 톱케이스(5)의 상부에다 스트레이너와 수중펌프 및 이송관을 차례로 연결하여 지하수의 물을 육상으로 펌핑시키는데 사용하게 되는 바, 장기 사용으로 회전씰(9A)이 마모되었을 때 모우터축(1)의 틈새로 유입되는 물은 모우터축(1)에 설치되어 있는 임펠러(11D)에 닿게되는데, 이때 임펠러(11D)의 정지시는 임펠러(11D)사이에 물이 일정량이 머물게되며 회전시는 축중심에서 바깥축으로 임펠러(11D)에서 원심력이 발생하여 들어온 물과 물에 함유되어있는 모래등의 고체입자는 필터(11C)에 부딪히게 되며, 물은 필터(11C)에 흡수되고 모래는 필터(11C)에 걸려지게 되고, 전극판(11B)과 전극판(11B)사이의 전기적저항이 무한대의 전기 저항에서 제로(영)의 방향으로 저항치가 떨어지기 시작하여 지상에 설치된 전기콘트롤박스(13)의 임으로 설정한 저항값에 도달하면 자동적으로 모우터는 정지되고 동시에 경보장치가 울리게 된다.The present invention is connected to the upper part of the top case (5), the strainer and the submersible pump and the transfer pipe in order to be used to pump groundwater water to the land, when the rotary seal (9A) is worn for a long time The water flowing into the gap of the motor shaft 1 touches the impeller 11D installed on the motor shaft 1, and when the impeller 11D is stopped, a certain amount of water stays between the impellers 11D. During rotation, centrifugal force is generated from the impeller 11D from the shaft center to the outer shaft, and solid particles such as sand and sand contained in the water collide with the filter 11C, and water is absorbed by the filter 11C. The sand is caught by the filter 11C, and the electric resistance between the electrode plate 11B and the electrode plate 11B starts to drop in the direction of zero (zero) from the infinite electric resistance, and the electric control installed on the ground. Set to box 13 When it reaches the resistance automatically Motor emitter is stopped at the same time alert an alarm.
이에 따라 회전씰(9A)이 마모되었음을 알 수 있게 되어 적기에 회전씰(9A)을 교체할 수 있는 것이다.Accordingly, it can be seen that the rotary seal (9A) is worn, it is possible to replace the rotary seal (9A) in a timely manner.
이와 같은 본 고안은 필터기능을 겸한 수분검출기를 설치하여 회전씰(9A)이 장기사용으로 마모되어 수중모우터내부와 지하수를 차단하는 능력이 저하되었을때 지하수와 지하수가 함유된 미세한 모래가 내부로 유입되는 것을 방지하므로서 베어링과 코일등 내장된 부품의 손상을 방지함과 동시에 필터의 수분의 함량을 전기적저항으로 검출함으로서 자동으로 작동을 정지시키고, 경보를 울리게 하여 회전씰을 적기에 새것으로 교체시킬 수 있도록하여 모우터의 사용수명을 연장시킬 수 있는 효과가 있다.The present invention is such that the installation of a water detector that also has a filter function, when the rotary seal (9A) is worn by long-term use and the ability to block the inside of the underwater motor and groundwater is reduced, the fine sand containing the groundwater and groundwater into the interior It prevents inflow and prevents damage to the parts inside the bearings and coils, and simultaneously detects the water content of the filter with an electrical resistance to automatically stop the operation and raises an alarm to replace the rotating seal with a new one in a timely manner. It has the effect of extending the service life of the motor.
