본 고안은 모터의 축에 삽지되어 회전되지 않을 때에는 축수공 틈새를 막고 회전할 때에는 마찰 저항이 없는 모터펌프 회전축의 디스크 패킹에 관한 것이다.The present invention relates to a disk packing of a motor pump shaft that does not have frictional resistance when the shaft is inserted into the shaft of the motor and is not rotated to close the shaft hole clearance and rotate.

본 고안은 특히 본원 출원인이 개발한 무패킹 펌프(실용신안 제31649호)에 사용하면 유리한 것으로 무패킹 펌프는 임펠라를 회전시키는 모터축을 패킹이 없이도 액을 누출 없이 이송시킬수 있는 펌프로써 액 탱크 하단부에 설치하여 상단에 위치한 저장 탱크로 액을 이송시킬수 있게한 것이다.The present invention is particularly advantageous when used in an unpacking pump (utility model No. 31649) developed by the applicant of the present application. The unpacking pump is a pump that can transfer the liquid without leaking the motor shaft for rotating the impeller without the packing. It is installed so that the liquid can be transferred to the storage tank located at the top.

그런데 상기 펌프는 어떤 계기로 인해 가동이 중단되었을 때에는 상단에 위치한 저장 탱크내의 액이 펌프내로 역류하여 무패킹의 축수공 사이로 누출되는 결점이 있다.However, when the pump is stopped due to a certain instrument, the liquid in the upper storage tank flows back into the pump and leaks between the unpacking bearing holes.

그래서 종래에는 펌프의 가동이 중단되었을 때에는 즉시 저장탱크에 부착된 밸브를 일일이 잠그는 번거로움을 감수하였다.Thus, conventionally, when the pump is stopped, it takes the hassle of immediately closing the valve attached to the storage tank.

본 고안은 이러한 번거로움을 해결하기 위해 모터축이 회전을 중단하면 패킹이 축수공을 폐쇄하고 모터축이 회전할때에는 종래의 무패킹의 경우와 같이 패킹에 의한 마찰저항을 받지 않게 한 디스크 패킹을 개발한 것으로 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.In order to solve this trouble, the present invention solves the trouble of the disc packing, in which the packing closes the bearing hole when the motor shaft stops rotating, and when the motor shaft rotates, it is not subjected to frictional resistance by the packing as in the case of the conventional non-packing. It is developed according to the accompanying drawings in detail as follows.

펌프회전축(12)과 축수공(6)사이를 막아 주는 탄성재질의 패킹(3)에 있어서 중앙에 위치하는 축수부(1)와 상측에 접합폐쇄부(4)를 갖는 주연부(2) 사이를 상향 만곡되게 구성함을 특징으로 하는 모터 펌프 회전축의 디스크 패킹으로서 미설명 부호 5는 케이싱 저면의 패킹 접면부, 7은 부구, 8은 공실, 9는 호오스, 10은 임펠라, 11은 모터를 나타낸다.In the packing 3 of the elastic material which blocks the pump rotation shaft 12 and the bearing hole 6 between the bearing part 1 located at the center and the peripheral part 2 having the joint closure part 4 thereon. Reference numeral 5 denotes a packing contact portion of the bottom of the casing, 7 is a bulge, 8 is a vacancy, 9 is a hose, 10 is an impeller, and 11 is a motor.

이상과 같이 구성된 본 고안의 펌프를 조립하기 전에 펌프축(12)에 삽지하여 패킹의 주연부 상면의 접합 폐쇄부(4)가 펌프의 케이싱의 접면부(5)에 접치되게 끼워 고정한다.Before assembling the pump of the present invention configured as described above, it is inserted into the pump shaft 12 to fix the joint closure portion 4 of the upper surface of the periphery of the packing so as to be in contact with the contact portion 5 of the casing of the pump.

펌프는 종래와 같이 저장 탱크와 이송 탱크의 사이에 장치하여 펌프를 가동하면 이송액은 임펠라에 의해 흡입구를 통해 배출구로 강제 이송되는바, 이때 이송액은 모터축과 펌프내의 각 중간 케이싱의 축수공 사이로 액이 상승하여 공실(8)에 까지 채워진다.When the pump is operated between the storage tank and the transfer tank as in the related art, the feed liquid is forced to the discharge port through the inlet by the impeller, and the transfer liquid is stored in the shaft of the motor shaft and each intermediate casing in the pump. The liquid rises in between and fills the vacancy (8).

공실(8)까지 채워진 누액은 일정 수위를 유지하게 되면 부구가 부상하여 호오스(9)를 개통시켜 누액을 호오스를 통해 흡입구로 재 이송시켜 흡입구의 흡입력에 의해 다시 배출구로 이송되는바, 어떤 이유에 의해 모터가 가동을 정지하면 이송되던 액이 자연압에 의해 펌프내로 역류하여 축수공과 호오스를 통해 상부 공실(8)에 충만되는데 이때에는 임펠라가 회전하지 않으므로 호오스를 통한 반송이 없게 되므로 액은 결국 펌프 상부의 케이싱의 축수공(6)으로 누출되게 된다.When the fluid is filled up to the vacancy (8) maintains a certain level, the float floats to open the hose (9) to transfer the fluid back to the inlet through the hose to the outlet by the suction force of the inlet, for some reason When the motor stops running, the conveyed liquid flows back into the pump by natural pressure and fills the upper chamber 8 through the bearing hole and the hose. At this time, since the impeller does not rotate, there is no return through the hose, so the liquid eventually pumps. Leakage into the bearing 6 of the upper casing.

본 고안은 이러한 케이싱의 축수공(6) 주연의 접면부(5)에 모터축(12)에 긴밀히 삽지된 디스크형 패킹의 주연부(2) 상면의 접면부, 즉 접합 폐쇄부(4)가 접합되어 있으므로 축수공(6)으로 통한 액의 누출현상을 예방할 수가 있다.According to the present invention, the contacting part of the upper surface of the peripheral part 2 of the disc-shaped packing closely inserted into the motor shaft 12 is connected to the contacting part 5 around the bearing hole 6 of the casing, that is, the joint closure part 4 is joined. Therefore, it is possible to prevent the leakage of the liquid through the water storage hole (6).

더구나 공실(8)내에 가득 채워진 누액의 압력에 의해 디스크형 패킹 주연부(2)를 더욱 가압하므로 그 밀접도가 더욱 높아 누수현상을 더욱 어려워진다.In addition, since the disk-shaped packing periphery 2 is further pressurized by the pressure of the leaked liquid filled in the vacancy 8, the tightness becomes higher and the leakage phenomenon becomes more difficult.

이렇게 모터의 정지상태에서는 디스크형 패킹의 주연부 상면이 케이싱 저면에 접면되어 있어 액의 누출을 방지하고 있다가 다시 모터가 가동되어 펌프축(12)이 회전하면 디스크형 패킹은 회전 원심력에 의해 주연의 절곡부, 즉 상향 만곡 구성된 축수부(1)와 주연부(2)사이가 퍼지면서 수평을 유지하므로 패킹의 접면부, 즉 접합 폐쇄부(4)가 케이싱의 저면 접면부(5)에서 빨리되어 디시크형 패킹이 회전하는데 대한 마찰 저항을 배제할수가 있는 것이다.In the standstill state of the motor, the upper surface of the peripheral part of the disk-type packing is in contact with the bottom of the casing to prevent leakage of liquid. Then, when the motor is started and the pump shaft 12 rotates, the disk-type packing is subjected to rotational centrifugal force. Since the bent portion, that is, the horizontally spreading portion between the bearing portion 1 and the periphery portion 2, which is upwardly curved, is maintained horizontally, the contact portion of the packing, that is, the junction closure portion 4, is accelerated at the bottom contact portion 5 of the casing. It is possible to exclude the frictional resistance against rotation of the cradle packing.

그리고 공실에 가득 채워진 액은 임펠라의 흡입력에 의해 호오스를 통해 환원되고 이는 다시 흡입구로 이송되어 배출되므로 모터가 가동되는 상태로 복귀된다.And the liquid filled in the vacancy is reduced through the hose by the suction force of the impeller, which is transported to the suction port and discharged again, so that the motor is returned to the operating state.

이렇게 되므로 공실에 채워진 액은 다시 일정 수준을 유지하므로 디스크 패킹이 회전하여 축수공(6)을 개방하더라도 축수공(6)을 통한 누수현상은 배제되는 것이다.Since the liquid filled in the vacancy thus maintains a constant level, even if the disc packing is rotated to open the bearing hole 6, the leakage phenomenon through the bearing hole 6 is excluded.

이와같이 본 고안은 펌프의 가동중 어떤 이유에 의해 모터의 회전이 중단되었을 때 액의 누출현상이 없으므로 제때에 일일이 저장 탱크나 이송탱크의 밸브를 잠그지 않아도 되며 모터의 축이 회전하지 않을 때에는 축수공을 막아주고 있다가 모터의 축이 회전하게 되면 접면부가 떨어지므로 무부하인 무패킹 펌프와 같은 효과를 그대로 유지할 수가 있다.In this way, there is no leakage of liquid when the rotation of the motor is stopped for some reason during the operation of the pump. Therefore, it is not necessary to lock the valve of the storage tank or the transfer tank in time, and when the shaft of the motor does not rotate, When the shaft of the motor rotates to prevent the contact area from falling off, the same effect as the no-load pumpless pump can be maintained.
