본 고안은 지하수속에 설치하여 지하수를 펌핑하는 수중 펌프용 수중모우터에 관한 것으로서, 본 출원인이 이미 취득한 실용신안등록 제44943호의 수중모우터를 더욱 개량하여 톱케이스의 회전부에 조립되어 있는 회전씰이 마모되어 지하수속에 함유되어 있는 미세한 모래입자가 수중 모우터내부에 유입됨으로 인하여 누전, 합선등의 고장발생과 베어링의 급속한 마모를 방지하기 위하여 톱케이스의 내부모우터측에 물을 흡수하고, 모래를 걸러내는 필터(FILTER)를 겸한 수분검출기를 고정하여 모래를 필터에 걸려지게 하여 모우터내부로 유입되는 것을 방지함으로서, 베어링등 내부의 부품을 보호하고, 물은 필터에 흡수되게 하여 이를 지상에 설치된 전기콘트롤박스에 전기적 저항으로 측정될 수 있도록 하고, 일정치의 저항값이 되었을 때 수중모우터가 자동으로 정지되고, 경보가 울리게 하여 이의 원인이 된 회전씰을 적기에 교체시킬 수 있도록 하고, 또한 수중모우터의 앤드케이스에는 불활성가스충전용 플러그를 설치하여 내부를 불활성가스로 충진할 수 있도록 하여 모우터내부의 코일의 피막, 회전부의 윤활유등과 내장된 부품의 작동중 발생될 수 있는 산화등 화학작용을 미연에 방지함으로서, 이에 의한 고장원인을 제거하고, 전기적효율을 극대화시켜 성능을 향상시킬 수 있도록 한 수중모우터를 안출하게 된 것인데 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention relates to a submersible motor for a submersible pump installed in an underground water pump to pump groundwater, and the rotary seal which is assembled to the rotating part of the top case by further improving the submersible motor of Utility Model Registration No. 444943 that the applicant has already acquired. As the fine sand particles that are worn and contained in the groundwater flow into the underwater motor, water is absorbed to the inner motor side of the top case to prevent breakdown, short circuit, etc. and rapid wear of the bearing. By fixing the water detector which also filters the filter, it prevents the sand from being caught in the filter and prevents it from entering the inside of the motor.It protects the parts inside the bearings, and the water is absorbed by the filter so that it is installed on the ground. Underwater motor can be measured with electric resistance in electric control box. It stops automatically and makes an alarm sound so that the rotating seal that caused it can be replaced in a timely manner, and an inert gas filling plug is installed in the end case of the underwater motor so that the inside can be filled with inert gas. It prevents chemical reactions such as coil coating of the motor inside, lubricating oil of the rotating part and oxidation that may occur during operation of the built-in parts, thereby eliminating the cause of failure and maximizing electrical efficiency to improve performance. It is to be conceived a submersible motor that can be described in detail by the accompanying drawings as follows.

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 하고, 앤드케이스(6)에는 밀폐용마개(12A), 볼(12B), 스프링(12C) 오링(12D)(12E)으로 이루어진 불활성가스충전용 플러그(12)를 고정하여서 된 것이다.The upper part of the stator housing (2) provided with the coil (3) and the rotor (4) is a rotary seal cover of the permanent magnet (10A), the bearing (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, and the end case 6 has a sealing plug 12A. The ball 12B, the spring 12C, the ring 12 for inert gas filling consisting of the O-rings 12D and 12E is fixed.

미설명 부호 14는 불활성가스주입기의 노즐이다.Reference numeral 14 is a nozzle of the inert gas injector.

이와 같이 된 본 고안은 톱케이스(5)의 상부에다 스트레이너와 수중펌프 및 이송관을 차례로 연결하여 지하수의 물을 육상으로 펌핑시키는데 사용하게 되는바, 장기 사용으로 회전씰(9A)이 마모되었을 때 모우터축(1)의 틈새로 유입되는 물은 모우터축(1)에 설치되어 있는 임펠러(11D)에 닿게 되는데, 이때 임펠러(11D)의 정지시는 임펠러(11D)사이에 물이 일정량이 머물게 되며 회전시는 축중심에서 바깥축으로 임펠러(11D)에서 원심력이 발생하여 들어온 물과 훔에 함유되어 있는 모래등의 고체입자는 필터(11C)에 부딪히게 되며, 물은 필터(11C)에 흡수되고 모래는 필터(11C)에 걸려지게 되고, 전극판(11B)과 전극판(11B)사이의 전기적 저항이 무한대의 전기 저항에서 제로(0)의 방향으로 저항치가 떨어지기 시작하여 지상에 설치된 전기콘트롤박스(13)의 임으로 설정한 저항값에 도달하면 자동적으로 모우터는 정지되고, 동시에 경보장치가 울리게 된다. 이에 따라 회전씰(9A)이 마모되었음을 알 수 있게 되어 적기에 회전씰(9A)을 교체할 수 있는 것이다.In this way, the present invention is connected to the upper part of the top case (5) by the strainer and the submersible pump and the transfer pipe to be used to pump the groundwater water to the ground bar, when the rotary seal (9A) is worn for a long time The water flowing into the gap of the motor shaft 1 comes into contact with the impeller 11D installed on the motor shaft 1, at which time a certain amount of water stays between the impellers 11D when the impeller 11D is stopped. At the time of 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 hum hit 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 from zero electrical resistance to an electric control installed on the ground. Set to box 13 When it reaches the resistance value and the emitter Motor stop automatically, at the same time it alert an alarm. 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.

불활성가스를 주입코저 할때는 앤드케이스(6)에 설치되어 있는 불활성가스충전용 플러그(12)는 제8도와 같이 밀폐용마개(12A)를 분리하고, 끝이 V홈으로 된 진공펌프의 흡입노즐이나 불활성가스주입기의 노즐(14)을 플러그(12)의 구멍을 통하여 밀어 넣으면 오링(12D)(12E)은 불활성가스주입기의 노즐(14)가 밀착됨과 동시에 볼(12B)은 밀려 기체가 흐를 수 있는 통로가 형성되며 이 통로를 통하여 모우터내부를 진공으로 만들거나 불활성가스를 충전하게 되며, 불활성가스충전이 완료되면 밀폐용마개(12A)로 밀폐시키면 된다.When inert gas is injected, the inert gas filling plug 12 installed in the end case 6 removes the sealing plug 12A as shown in FIG. 8, and the suction nozzle of the vacuum pump having the V groove at the end thereof. When the nozzle 14 of the inert gas injector is pushed through the hole of the plug 12, the O-rings 12D and 12E are brought into close contact with the nozzle 14 of the inert gas injector and the ball 12B is pushed to allow gas to flow. A passage is formed and through this passage, the inside of the motor is vacuumed or filled with inert gas, and when the inert gas filling is completed, the sealing plug 12A may be sealed.

이와 같은 본 고안은 필터기능을 겸한 수분검출기를 설치하여 회전씰(9A)이 장기사용으로 마모되어 수중모우터내부와 지하수를 차단하는 능력이 저하되었을 대 지하수와 지하수가 함유된 미세한 모래가 내부로 유입되는 것을 방지하므로서, 베어링과 코일등 내장된 부품의 손상을 방지함과 동시에 필터의 수분함량을 전기적 저항으로 검출함으로서 자동으로 작동을 정지시키고, 경보를 울리게 하여 회전씰을 적기에 새것으로 교체시킬 수 있도록 하여 모우터의 사용수명을 연장시킬 수 있도록 하고, 앤드케이스(6)에는 불활성가스를 주입시킬 수 있는 불활성가스충전용 플러그(12)를 설치하여 수중모우터의 내부를 불활성가스로 충진함으로서, 모우터 내부의 예상되는 화학작용을 미연에 방지함으로서 이에 의한 고장원인을 제거하고, 전기적 효율을 높여 성능의 향상은 물론 전력을 절감시킬 수 있는 효과가 있다.The present invention is designed to install a water detector that also functions as a filter, and the rotary seal (9A) is worn out for long periods of time, which reduces the ability to block the inside of the underwater motor and groundwater. By preventing the inflow, it prevents damage to the parts inside the bearings and coils, and also detects the water content of the filter with an electrical resistance to automatically stop the operation and makes an alarm sound to replace the rotating seal with a new one in a timely manner. It is possible to extend the service life of the motor, and by installing an inert gas plug 12 for inert gas into the end case 6 to fill the inside of the underwater motor with inert gas. In order to prevent the expected chemical reaction inside the motor, it is possible to eliminate the cause of failure and increase the electrical efficiency. This will not only improve performance but also save power.
