본 발명은 하우징 고정체의 누수방지 장치에 관한 것으로, 더욱 상세하게는 펌프 하우징내에 형성된 임펠러를 회전 구동시키는 샤프트가 외부의 모우터 구동력을 전달받기 위하여 하우징고정체를 관통하여 회전되는 것에 있어서, 하우징 고정공 후방으로 일체로한 덮게편내에 관통공으로 알리코 자석이 고정된 샤프트를 관통시켜 알리코 자석을 중심으로 공간부가 양측으로 형성되게 하여, 사기 알리코 자석 양측 공간부에 실리콘액과 자석분말을 충진시켜 하우징 고정체에서 누수 방지토록 한 것이다.The present invention relates to a device for preventing leakage of a housing fixture, and more particularly, a shaft for rotationally driving an impeller formed in a pump housing, wherein the shaft rotates through the housing fixture to receive an external motor driving force. Through the shaft, which is fixed to the Alko magnet through the through hole in the cover piece integrally behind the fixing hole, the space is formed on both sides around the Alico magnet, and the silicone liquid and the magnetic powder are filled in the space on both sides of the Alko magnet. This is to prevent leakage from the fixture.

종래의 펌프에 있어서는, 모우터 구도에 따라 임펠러와 연결형성된 샤프트를 회전구동시켜 펌프본체의 유, 출입구로 물리 유동되는 것이나, 유입구로부터 유입된 물리 하우징내에서 포화 상태가 되어 모우터와 연결된 샤프트와 하우징 관통공사이에서 누수되어 펌프의 제기능이 유지되지 않았던 것으로, 이를 개선하고자 일반적으로 모우터와 연결된 샤프트가 관통되는 하우징 관통공에 누수방지용 팩킹등으로 1차 누수방지 보호층과 2차 누수방지 보호층을 형성하여서 모우터의 샤프트와 연결 구동되는 임펠러 샤프트를 관통시켜 사용하였던 것이다.In the conventional pump, the shaft connected to the impeller according to the motor structure is rotated to physically flow to the oil body and the inlet and the outlet of the pump body, or to be saturated in the physical housing introduced from the inlet and the shaft connected to the motor. The pump was not maintained due to leakage of the housing penetrating work.In order to improve this, the primary leakage protection layer and the secondary leakage protection protection are generally provided by a leakage preventing packing in the housing through hole through which the shaft connected to the motor penetrates. Forming a layer was used to penetrate the impeller shaft which is driven in conjunction with the shaft of the motor.

그러나, 상기와 같은 1, 2차 누수방지 보호를 위한 팩킹을 설치하기 위한 하우징 고정체의 구조가 복잡하여서 제품의 조립과정이 까다로워 생산성 저하의 요인이 되었고, 모우터와 연결 회전 구동되는 샤프트의 장기간 사용하다 보면 1, 2차 누수방지 보호층이 샤프트의 회전 접촉 마찰로 파손되어 누수방지 기능을 상실해 버리는 경우가 종종 야기되어 펌프이 신뢰도를 저하시키는 문제점이 초래 되었던 것이다.However, due to the complicated structure of the housing fixture for installing the packing for the first and second leakage prevention protection as described above, the assembly process of the product is difficult, which leads to a decrease in productivity, and the long-term operation of the shaft driven and connected to the motor In use, the primary and secondary leakage protection layers are often broken by rotational contact friction of the shaft, which causes the leakage protection function to be lost, causing the pump to lower reliability.

본 발명은 상기와 같은 문제점을 해결하기 위하여, 하우징 고정체에 샤프트가 관통되어 회전되게 한 것에 있어서, 하우징 고정체와 일체로한 덮개편 내에, 외주측으로 알리코 자석을 형성된 샤프트를 관통하여 회전이 자유롭게 설치하여 알리코 자석을 중심으로 덮개편내에 공간부가 형성되게 한 것이다.In order to solve the above problems, the present invention is to allow the shaft to penetrate the housing fixture to rotate, freely rotating through the shaft formed with an alico magnet on the outer circumference of the cover piece integrated with the housing fixture. By installing it, the space part is formed in the cover piece centering on the alico magnet.

그리고, 상기 공간부내에는 실리콘액과 자석분말을 주사기 등의 일정 수단으로 충진하여, 샤프트와 하우징 고정체의 덮개편 사이에서 실리콘액과 자석분말이 응집되어 알리코 자석에 자성 접착되게한 것으로서, 자성과 응집력을 이용하여 하우징 고정체와 샤프트로 형성된 공간부에서 누수되는 것을 방지토록 한 것이다.In the space part, the silicone liquid and the magnetic powder are filled by a predetermined means such as a syringe, and the silicone liquid and the magnetic powder are agglomerated between the shaft and the cover piece of the housing fixing body so as to be magnetically bonded to the alico magnet. Cohesion is used to prevent leakage in the space formed by the housing fixture and the shaft.

따라서, 본 발명으 목적은, A1, Ni, Co 로써 주를 이루는 알리코 자석과, 자석분말과, 실리콘액으로 종래와 같은 누수방지층이 필요없이 간단히 하여 높은 누수방지 효과로 반영구적으로 사용할수 있도록 한 것이고, 이에 따르는 펌프의 조립부품수가 일층더 감소되어 조립시간을 단축 시킬수 있어 생산성 향상을 꾀할수 있도록 한 것이다.Accordingly, an object of the present invention is to provide semi-permanent use with a high leakage preventing effect simply by eliminating the conventional leakage preventing layer with an alico magnet composed mainly of A1, Ni, Co, magnetic powder, and silicone liquid. As a result, the number of assembly parts of the pump can be further reduced, thereby shortening the assembly time, thereby improving productivity.

본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다. 도면에서와 같이, 하우징고정체(1)에 모우터(도시생략)의 구동력이 전달되는 샤프트(2)가 관통되어 회전되게 한것에 있어서, 하우징고정체(1)의 후방으로 덮개편(3)을 일체로 연장하여, 샤프트(2)가 관통공(4)과, 하우징고정체(1)와, 덮개편(3)으로 관통되도록 형성한 것으로, 샤프트(2)의 외주에는 고성능 자석인 알리코 자석(5)을 형성하여, 상기 관통공(4)과 덮게편(3)에 의하여 형성되는 공간부(6)에 알리코 자석(5)을 형성한 샤프트(2)를 관통시키어 하우징고정체(1)의 덮개편(3)내에서 알리코자석(5)을 중심으로 공간부(6')(6")가 형성되게 한다.The present invention will be described with reference to the accompanying drawings. As shown in the figure, the shaft 2 through which the driving force of a motor (not shown) is transmitted to the housing fixing body 1 is rotated so that the lid piece 3 is rearward of the housing fixing body 1. , The shaft 2 is formed so as to penetrate through the through hole 4, the housing fixing body 1, and the lid piece 3, and the outer periphery of the shaft 2 is an alico magnet which is a high performance magnet. (5) to form a housing (1) by passing through the shaft (2) formed with the alico magnet (5) in the space (6) formed by the through hole (4) and the cover piece (3). In the cover piece 3, the space 6 'and 6 " are formed around the alico magnet 5.

다음 샤프트(2)에 고정시킨 알리코자석(5)을 중심으로 형성된 공간부(6')(6")에는 실리콘액과 자석분말을 충진시켜서, 실리콘액과 자석분말이 응집되어 자력으로 알리코 자석(5)주변부에서 밀착 응집되는 밀폐효과로 누수를 방지할 수 있도록 형성한 것이다. 그리고, 하우징고정체(1)에서 연장시킨 덮게편(3)의 끝단(7)을 덮개편(3)으로부터 분리 및 고정할 수 있는 수단에 의하여 알리코자석(5)이 형성된 샤프트(2)를 하우징고정체(1)의 덮개편(3)내로 관통 시킬수 있는 것이다.Next, the spaces 6 'and 6 "formed around the alico magnets 5 fixed to the shaft 2 are filled with the silicon liquid and the magnet powder, and the silicon liquid and the magnet powder are agglomerated to form an alico magnet by magnetic force. 5) It is formed to prevent leakage due to the sealing effect that is tightly agglomerated in the peripheral portion, and the end 7 of the cover piece 3 extending from the housing fixing body 1 is separated from the cover piece 3 and It is possible to penetrate the shaft (2) formed with the alico magnet (5) into the cover piece (3) of the housing fixing body (1) by means of fixing.

상기와 같이된 본 발명의 작용효과를 상술하면, 도면에서와 같이, 하우징고정체(1)의 관통공(4)과 덮개편(3)의 관통공(4)으로 알리코자석(5)이 형성된 샤프트(2)를 관통시킨후 덮개편(3)의 공간부(6')(6")에 실리콘액과 자석분말 분말을 혼합하여, 주사위 따위로 주입하면, 덮개편(3)내에 알리코 자석(5)중심으로 형성된 공간부(6')(6

Figure kpo00001
)에 실리콘액과 자석분말이 충진되어 알리코자석(5)을 중심으로 충진된 실리콘액과 자석분말이 자성 접착되어 공간부(6)로 누수가 방지되는 것이다.Referring to the operation and effect of the present invention as described above, as shown in the drawings, the through-hole 4 of the housing fixing body 1 and the through-hole 4 of the cover piece 3 is formed with an alico magnet 5 After penetrating the shaft 2, the silicone liquid and the magnetic powder are mixed in the space portions 6 'and 6 "of the lid 3, and injected into a die. 5) Space portion 6 'formed at the center (6
Figure kpo00001
) Is filled with the silicone liquid and the magnetic powder, and the silicone liquid and the magnetic powder filled around the alico magnet 5 are magnetically bonded to prevent leakage into the space part 6.

이때 샤프트(2)에 고정 형성된 알리콘자석(5)과 실리콘약가 1차 응집된 자석분말을 서로의 자력에 의하여 당기어져 2차 응집됨으로써 밀착유지 되기 때문에 샤프트(2) 및 이 샤프트(2)에 고정 형성된 알리코 자석(5)과 실리콘액과 1차 응집된 자석분말은 샤프트(2)가 회전되게 됨에 따라 함께 회전하게 되는 것이고, 하우징고정체(1)의 덮개편(3)과 실리콘액과 1차 응집된 자석분말과는 2차 응집에 의하여 맞닿고 있을뿐 서로 아무런 당김력이 발생하기 않기 때문에 샤프트(2)가 회전하는 회전력에 아무런 저항을 주기 않게 됨으로 샤프트(2)및 이 샤프트(2)에 고정 형성된 알리코 자석(5)는 실리콘약과 1차 응집된 자석분말과 함께 회전 가능하게 되는 것이다.At this time, the alicon magnet 5 fixed to the shaft 2 and the silicon medicine are firstly agglomerated by the magnetic force of the magnetic powder, and the second agglomeration is maintained by close contact with the shaft 2 and the shaft 2. The fixedly formed alico magnet 5 and the silicon liquid and the first agglomerated magnet powder are rotated together as the shaft 2 is rotated, and the cover piece 3 and the silicone liquid and 1 of the housing fixture 1 are rotated together. The shaft 2 and the shaft 2 are not in contact with the secondary agglomerated magnet powder by the second agglomeration but do not generate any pulling force. The alico magnet 5 fixed to it is made to be rotatable with the silicon medicine and the first agglomerated magnet powder.

즉, 자석분말은 산화철 분자로 이루원진것으로 어떠한 액성에서도 녹슬거나 파괴될 우려가 없는 것이고, 상온에서 매우 안정되고 응집력이 큰 실리콘액과 자석분말을 혼합하게 되면 응집된 실리콘과 자석분말을 어떠한 액체가 관통하기 못하기 대문에 A1, Ni, Co로 주를 이루고 있는 고성능 영구 자석인 알리코자석(5)에 응집된 실리콘액과 자석분말이 알리코자석(5)을 중심으로 덮개편(3)내의 공간부(6)로 누수되는 물을 차단하게 되는 것이다.In other words, the magnetic powder is composed of iron oxide molecules, and there is no risk of rust or destruction in any liquid. When the liquid and the highly stable and cohesive silicon liquid are mixed at room temperature, the liquid is mixed with the agglomerated silicon and the magnetic powder. Due to the inability to penetrate, the silicon liquid and the magnetic powder agglomerated in the alico magnet (5), which is a high-performance permanent magnet mainly composed of A1, Ni, and Co, have a space in the cover piece (3) around the alico magnet (5). (6) to block the water leaking.

한편, 자석은 평면보다 모서리 부분에서 큰 자성이 유지되기 때문에 샤프트(2)에 형성된 알리코자석(5)에도 모서리 부분에서 큰 자력으로 실리콘액과 자석분말이 자성 접착되어, 공간부(6)에서 최소 공간인 알리코자석(5)의 상면과 덮개편(3)의 저면 부분에서 더욱더 실리콘액과 자석분말이 응집되어 자성 접착되는 것이다.On the other hand, since the magnet is maintained at the edge portion larger than the plane, the silicon liquid and the magnetic powder are magnetically bonded to the alico magnet 5 formed on the shaft 2 with a large magnetic force at the edge portion, thereby minimizing the space in the space portion 6. In the upper surface of the alico magnet 5, which is a space, and the bottom portion of the lid piece 3, the silicon liquid and the magnetic powder are further aggregated and magnetically bonded.

따라서, 샤프트(2)의 회전시에 공간부(6)에 충진된 실리콘액과 자석분말의 응집력으로 알리코자석(5)에 자성접착 되어 공간부(6')(6")의 누수를 차단할 수 있는 것이므로, 종래와 같으 1차 누수방지층과 2차 누수방지층을 형성시키기 위한 복잡한 구조를 저면 제거시킨 것으로 까다로웠던 제작 과정이 용이하게 되고, 이에 따르는 조립 부품수가 한증 감소되어 생산성 향상 및 제작비용이 절감되는 것이며, 또한 알리코자석(5)및 응집된 실리콘액과 자석분말로써 반영구적으로 사용할 수 있는 것이다.Therefore, when the shaft 2 rotates, it is magnetically bonded to the alico magnet 5 by the cohesive force of the silicon liquid and the magnet powder filled in the space 6, thereby preventing leakage of the spaces 6 'and 6 ". As it is, it is easy to make a difficult manufacturing process by removing the complex structure for forming the primary leak prevention layer and the secondary leak prevention layer as in the prior art, and the number of assembly parts is reduced accordingly, thereby improving productivity and manufacturing cost. In addition, it can be used semi-permanently as the alico magnet 5 and the agglomerated silicon liquid and the magnetic powder.
