본 발명은 선박의 스크류축의 밀폐부나 자동차 및 모우터 등의 밀폐부 내부로 이물질 및 수분이 유입되므로 인한 고장발생을 방지할 수 있도록 한 밀폐용 회전기계의 수분검출장치에 관한 것이다.The present invention relates to a water detection device of a sealed rotary machine to prevent the occurrence of failure due to the inflow of foreign matter and water into the sealed portion of the screw shaft of the ship or the sealed portion of the motor and motor.

종래의 밀폐용 회전기계는 장기사용으로 회전씰이 마모될 경우에 이물질, 수분이 밀폐용 회전기계의 내부로 유입되므로 인하여 내부의 부품이 조기에 손상케 되어 사용수명을 단축시키게 되었다.Conventional sealing rotary machine is due to the long-term use of the rotary seal wears foreign matter, moisture is introduced into the interior of the sealing rotary machine due to the internal parts are damaged early to shorten the service life.

본 발명은 상기와 같은 문제점을 해결하기 위하여 회전축의 주위의 기체의 내벽면에는 절연 케이스를 고정하여 이의 내에는 일정한 간격으로 수개의 전극판이 매입되고, 각 전극판의 사이에는 요입홈을 형성한 필터 (FILTER)를 고정하고, 필터의 요입홈에는 회전축에 고정한 임펠러를 끼우고 각 전극판은 전기콘트롤박스와 도선으로 연결하여 임펠러의 회전원심력에 의하여 유입수에 함유된 이물질은 필터에 걸려지게 하고, 물은 필터에 흡수되게 하여 이를 전기 콘트롤박스에 전기적 저항으로 측정할 수 있도록 하여 저항값이 제로(영)에 가깝게 떨어지게 됨과 동시에 전기 콘트롤박스의 전기회로에 의하여 회전축은 정지되고, 버저가 울리도록하여 이의 원인이 된 회전씰을 적기에 교체할 수 있도록 한 밀폐용 회전기계의 수분검출장치를 발명하게 된것인데, 본 발명을 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention is fixed to the inner case of the inner wall of the gas around the rotary shaft in order to solve the above problems, several electrode plates are embedded therein at regular intervals, and the filter formed a recess groove between each electrode plate (FILTER) is fixed, and the impeller fixed to the rotating shaft is inserted in the inlet groove of the filter, and each electrode plate is connected with the electric control box and the conductor so that foreign substances contained in the inflow water are caught on the filter by the impeller's rotation centrifugal force Is absorbed by the filter so that it can be measured as an electrical resistance in the electrical control box so that the resistance value is close to zero (zero), and at the same time, the rotating shaft is stopped by the electric circuit of the electrical control box, and the buzzer sounds Invented the water detection device of the sealed rotary machine to replace the cause of the rotating seal in a timely manner Although, the present invention will be described in detail with reference to the accompanying drawings.

기체(1)에 베어링(3)(4)으로 유착한 회전축(2)주위에 회전씰카버(5)로 회전씰(6)을 고정하여서 된 공지의 것에 있어서, 기체(1)의 내벽면에는 절연케이스(7)를 고정하여 상기의 절연케이스(7)내에는 일정한 간격으로 수개의 전극판(8)이 매입되고 각 전극판(8)의 사이에는 요입홈(9A)을 형성한 필터(9)를 고정하고, 상기의 필터(9)의 요입홈(9A)에는 회전축(2)에서 고정한 임펠러(10)를 끼우고, 각 전극판(8)은 전기 콘트롤박스(12)에 연결하여 저항값이 제로에 근접하게 되면 전기콘트롤박스(12)의 전기회로에 의하여 회전축(2)은 정지되고 버저(13)가 울리도록 하여서 된 것이다.In the well-known thing which fixed the rotary seal 6 with the rotary seal cover 5 around the rotating shaft 2 which adhered to the base 1 with the bearing 3 and 4, the inner wall surface of the base 1 A filter 9 in which several electrode plates 8 are embedded at regular intervals in the insulating case 7 by fixing the insulating case 7, and recesses 9A are formed between the electrode plates 8. ), And the impeller 10 fixed on the rotation shaft 2 is inserted into the recess 9A of the filter 9, and each electrode plate 8 is connected to the electrical control box 12 to provide a resistance value. When it approaches this zero, the rotary shaft 2 is stopped by the electric circuit of the electric control box 12 and the buzzer 13 is to ring.

이와 같이 된 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention as described above are as follows.

장기사용으로 회전씰(6)이 마모되었을 때 회전축(2)의 틈새로 유입되는 물음 회전축(2)에 설치되어있는 임펠러(10)에 닿게 되는데, 이때 회전축(2) 및 임펠러(10)의 정지시에는 임펠러(10) 및 필터(9) 사이에 물이 일정량 머물게되어 회전시에는 축중심에서 바깥축으로 발새오디는 임펠러(10)의 원심력에 의하여 유입된 물에 함유되어 있는 이물질의 고체입자는 필터(9)에 부딪혀 필터(9)에 걸려지게되고 물은 필터(9)에 흡수된다.When the rotary seal 6 is worn out for a long time, the impeller 10 installed in the rotary shaft 2 is introduced into the gap of the rotary shaft 2, and at this time, the rotary shaft 2 and the impeller 10 are stopped. During the rotation, a certain amount of water stays between the impeller 10 and the filter 9. During rotation, the solid particles of the foreign matter contained in the water introduced by the centrifugal force of the impeller 10 move from the shaft center to the outer axis. The filter 9 is hit by the filter 9 and water is absorbed by the filter 9.

필터(9)에 흡수된 물기에 의하여 수개의 전극판(8)과 전극판(8)사이의 전기적 저항이 무한대의 전기저항에서 제로(0)의 방향으로 저항치가 떨어지기 시작하여 저항값이 제로에 근접하게 되면 전기콘트롤박스(12)의 전기회로에 의하여 자동적으로 회전축(2)의 구동장치는 정지되고 동시에 버저(13)가 울리게 된다.Due to the water absorbed by the filter 9, the electrical resistance between the several electrode plates 8 and the electrode plates 8 begins to drop in the direction of zero from zero electrical resistance, resulting in zero resistance. When close to, the drive of the rotary shaft 2 is automatically stopped by the electric circuit of the electric control box 12 and at the same time the buzzer 13 rings.

이에 따라 회전씰(6)이 마모되었음을 알수있게 되어 회전씰(6)을 적기에 교체할 수 있는 것이다.Accordingly, it can be seen that the rotary seal 6 is worn, it is possible to replace the rotary seal 6 in a timely manner.

이와 같은 본발명은 회전씰(6)이 장기사용으로 마모되어 내부로 유입되는 이물질과 부분을 자동검출하여 회전축(2)이 정지됨과 동시에 버저(13)가 울리게 되므로 회전씰(6)을 적기에 새것으로 교체하여 손상을 상지할 수 있게 되어 회전기계의 사용수명을 보다 연장시킬 수 있는 효과가 있다.This invention according to the present invention, the rotary seal (6) is worn out by long-term use, and automatically detects foreign substances and parts introduced into the inside, the rotating shaft (2) is stopped and at the same time the buzzer (13) will ring so that the rotary seal (6) It is possible to replace the new one to replace the damage, which has the effect of extending the service life of the rotating machine.
