본 고안은 지하수속에 설치하여 지하수를 펌핑하는 수중펌프용 불활성가스충전플러그를 설치한 수중모우터에 관한 것으로서, 본 출원인이 이미 취득한 실용신안등록 제44943호를 더욱 개량한 것으로 수중모우터의 앤드케이스에는 불활성가스충전용 플러그를 설치하여 내부를 불활성가스로 충진할 수 있도록 하여 모우터내부의 코일의 피막, 회전부의 윤활유 등과 내장된 부품의 작동중 발생될 수 있는 산화, 화학작용을 미연에 방지함으로서 이에 의한 고장원인을 제거하고 전기적효율을 극대화시켜 성능을 향상시킬 수 있도록 한 불활성가스충전플러그를 설치한 수중모우터를 안출한 것이다.The present invention relates to an underwater motor installed with an inert gas charging plug for an underwater pump installed in an underground water pump to pump underground water. An inert gas filling plug is installed in the inside to fill the inside with inert gas, thereby preventing oxidation and chemical action that may occur during operation of the coil coating on the inside of the motor, the lubricant in the rotating part, and the built-in parts. By removing the cause of the failure and maximizing the electrical efficiency to improve the performance of the submersible motor installed an inert gas charging plug was devised.

이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.When 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, 앤드케이스(6)에는 밀폐용마개(12A), 볼(12B), 스프링(12C), 오링(12D)(12E)으로 이루어진 불활성가스충전용플러그(12)를 고정하여서 된 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 end case 6 includes a sealing stopper 12A, a ball 12B, a spring 12C, and an O-ring 12D and 12E. The inert gas filling plug 12 is fixed.

미설명 부호 11은 수분검출기이고, 14는 불활성가스주입기의 노즐이다.Reference numeral 11 is a moisture detector, and 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 되는 바, 불활성가스를 주입코저 할 때는 앤드케이스(6)에 설치되어 있는 불활성가스충전용플러그(12)는 제6도와 같이 밀폐용마개(12A)를 분리하고 끝이 V홈으로 된 진고펌프의 흡입노즐이나 불활성가스주입기의 노즐(14)을 플러그(12)의 구멍을 통하여 밀어넣으면 오링(12D)(12E)은 불활성가스주입기의노즐(14)에 밀착됨과 동시에 불(12B)은 밀려 기체가 흐를수 있는 통로가 형성되며, 이 통로를 통하여 모우터 내부를 진공으로 만들거나 불활성가스를 충전하면 되며, 불활성가스충전이 완료되면 밀폐용마개(12A)로 밀폐시키면 된다.In this way, the present invention connects the strainer, the water pump, and the transfer pipe to the upper part of the top case 5, and is used to pump the water of the groundwater to the land. When the inert gas is injected, the end case (6) The inert gas filling plug 12 installed in the plug removes the sealing plug 12A as shown in FIG. 6 and plugs the nozzle 14 of the intake nozzle of the pump or the inert gas injector with the V-groove at the end thereof. O-ring (12D) (12E) is in close contact with the nozzle (14) of the inert gas injector and the fire (12B) is pushed through the hole of the inlet to form a passage through which the gas can flow, through the inside of the motor It is to make a vacuum or to fill the inert gas, and when the filling of the inert gas is completed by sealing with a sealing plug 12A.

이와 같은 본 고안은 앤드케이스(6)에는 불활성가스를 주입시킬 수 있는 불활성가스충전용플러그(12)를 설치하여 수중모우터의 내부를 불활성가스로 충진함으로서 모우터 내부의 예상되는 화학작용을 미연에 방지함으로서, 이에 의한 고장원인을 제거하고 전기적효율을 높여 성능의 향상은 물론 전력을 절감시킬 수 있는 효과가 있다.This invention devises an inert gas filling plug 12 capable of injecting inert gas into the end case 6 to fill the inside of the underwater motor with inert gas, thus preventing the expected chemical action inside the motor. By preventing it, it is possible to eliminate the cause of failure and increase the electrical efficiency, thereby improving the performance as well as saving the power.
