Description
본 고안은 보일러용 온수순환펌프에 관한 것으로서, 더욱 상세하게는 고온의 온수가 소통되는 펌프하우징과 모터가 설치된 모터케이싱 사이를 격리시키는 디비전하우징이 외부 충격에도 잘 견디면서 수압에 의한 변형을 최소화하는 보일러용 온수순환펌프에 관한 것이다.The present invention relates to a hot water circulation pump for a boiler, and more specifically, a division housing that isolates between a pump housing in which hot water is communicated with a motor casing in which a motor is installed, to withstand external shocks while minimizing deformation due to water pressure. It relates to a hot water circulation pump for boiler.
일반적으로 도 4에 도시된 바와 같이 펌프에 사용되는 디비전하우징(40)은 플라스틱 재질로 펌프하우징(10)과 모터케이싱(20) 사이에 결합되었으며, 모터케이싱(20)에 설치된 모터(30)의 냉각을 위해 외부의 공기가 모터케이싱(20)으로 유입될 수 있도록 통풍구(21)가 형성되어 있었다.In general, the division housing 40 used for the pump as shown in Figure 4 is a plastic material coupled between the pump housing 10 and the motor casing 20, the motor 30 of the motor casing 20 Ventilation holes 21 were formed to allow external air to flow into the motor casing 20 for cooling.
그러나, 이와 같은 종래의 구조는 디비전하우징(40)이 외부에 노출되어 있으므로, 순환펌프에 충격이 가해 졌을 경우 그 충격이 디비전하우징(40)에 그대로 전달되어 파손될 우려가 있었다.However, in the conventional structure, since the division housing 40 is exposed to the outside, when the shock is applied to the circulation pump, the shock is transmitted to the division housing 40 as it may be damaged.
한편, 디비전하우징(40)은 앞서 설명한 바와 같이 펌프하우징(10)과 모터케이싱(20)에 의해 수직방향으로 고정되되 통풍구(21)가 형성된 원주면이 외부로 노출되어 있어, 모터(30) 작동시 높은 압력을 받으면 수직방향뿐만 아니라 수평방향으로도 변형이 일어나 전체적인 변형폭이 컸다.On the other hand, the division housing 40 is fixed in the vertical direction by the pump housing 10 and the motor casing 20 as described above, but the circumferential surface on which the vent hole 21 is formed is exposed to the outside, thereby operating the motor 30. Under high pressure, the deformation occurred not only in the vertical direction but also in the horizontal direction, resulting in a large overall deformation width.
때문에, 디비전하우징(40)과 메카니칼 씰(60)의 밀착도가 떨어져 이때 발생된 틈새로 누수현상이 발생되는 문제점이 있었다.Therefore, the adhesion of the division housing 40 and the mechanical seal 60 is poor, there is a problem that the water leakage phenomenon occurs in the gap generated at this time.
본 고안은 상기와 같은 문제점을 개선하고자 안출된 것으로서, 디비전하우징을 펌프하우징과 모터케이스의 내측에 설치결합하여 외부충격으로부터 보호하고 수압에 따른 변형을 최소할 수 있도록 된 보일러용 온수순환펌프를 제공하는 것을 그 목적으로 한다.The present invention has been devised to improve the above problems, and provides a hot water circulation pump for a boiler that can be installed and combined with the division housing to the inside of the pump housing and the motor case to protect against external shock and to minimize deformation due to water pressure. It is for that purpose.

이하, 본 고안의 일실시예를 예시도면에 의거하여 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안의 일실시예에 따른 분리사시도를 도시한 것으로서, 펌프하우징(10)의 밑으로는 디비전하우징(40)과 모터케이싱(20)이 순차적으로 결합된다.1 is an exploded perspective view according to an embodiment of the present invention, the division housing 40 and the motor casing 20 are sequentially coupled to the bottom of the pump housing 10.
펌프하우징(10)은 온수가 소통되는 온수입구(11)와 온수출구(12)가 각각 형성되어 있으며, 몸체 외측으로는 볼트(100)가 체결되는 결합공(16)이 형성되어 있다.The pump housing 10 is formed with a hot water inlet 11 and a hot water outlet 12 through which hot water communicates, and a coupling hole 16 to which the bolt 100 is fastened to the outside of the body.
모터케이싱(20)은 하부에 모터(30)가 설치되고 상부에 디비전하우징(40)이설치되는 수납공간(80)이 형성되어 있다. 모터케이싱(20)의 상부면은 펌프하우징(10)의 결합면과 일치되게 형성되어 있으며, 상호 볼트(100)에 의해 체결될 수 있도록 상기 결합공(16)과 일치되는 결합공(26)이 형성되어 있다.The motor casing 20 has a storage space 80 in which a motor 30 is installed at a lower portion and a division housing 40 is installed at an upper portion thereof. The upper surface of the motor casing 20 is formed to match the coupling surface of the pump housing 10, the coupling hole 26 is matched with the coupling hole 16 to be fastened by the mutual bolt (100) Formed.
모터케이싱(20)의 외주면과 상하면에는 공기가 자유롭게 유동될 수 있는 통풍구(21)가 형성되어 있다.Vent holes 21 through which air can flow freely are formed on upper and lower outer surfaces of the motor casing 20.
수납공간(80)은 윗쪽으로 개방되어 있으며 개방측으로 단턱(25)이 형성되어 있다. 이 단턱(25)에는 접시형태로 된 디비전하우징(40)이 안착된다. 디비전하우징(40)은 펌프하우징(10)을 소통하는 물이 모터(30)쪽으로 유입되지 않도록 그 외주면 끝단이 단턱(25)에 밀착된다. 상기 단턱(25)은 모터케이싱(20)외 펌프하우징(10) 하부에 형성될 수 있으며, 상기 두 부재(10, 20) 중 한 부재에 선택적으로 형성될 수 있다.The storage space 80 is open upward and the stepped portion 25 is formed on the open side. The step housing 25 is mounted to the division housing 40 in the form of a plate. In the division housing 40, the end of the outer circumferential surface thereof is in close contact with the step 25 so that water communicating with the pump housing 10 does not flow into the motor 30. The step 25 may be formed below the motor housing 20 and the pump housing 10, and may be selectively formed on one of the two members 10 and 20.
상기 디비전하우징(40)은 도 3에 도시된 바와 같이 밑면에 수개의 리브(41)가 형성되어 있으며, 중앙에 모터(30) 축이 관통되는 축공(42)이 형성되어 있다. 이 축공(42)에는 기밀을 유지하기 위한 메카니칼 씰(60)이 결합된다. 한편, 상기 축공(42)은 메카니칼 씰(60)이 고정될 수 있도록 턱이 져 있다.As shown in FIG. 3, the division housing 40 has a plurality of ribs 41 formed at a bottom thereof, and a shaft hole 42 through which the shaft of the motor 30 penetrates is formed at the center thereof. The shaft hole 42 is coupled to the mechanical seal 60 for maintaining airtightness. On the other hand, the shaft hole 42 is a jaw so that the mechanical seal 60 can be fixed.
디비전하우징(40)과 펌프하우징(10)의 결합면 사이에는 외부로 누수되는 것을 방지하기 위해 오링(70)이 결합된다.The O-ring 70 is coupled between the division housing 40 and the coupling surface of the pump housing 10 to prevent leakage to the outside.
도 2는 본 고안의 일실시예에 따른 부분 단면도를 도시한 것으로서, 펌프하우징(10)과 모터케이싱(20)이 상하로 결합되어 있으며, 상기 두 부재(10, 20)의 내측에 디비전하우징(40)이 결합설치되어 있다.Figure 2 is a partial cross-sectional view according to an embodiment of the present invention, the pump housing 10 and the motor casing 20 is coupled up and down, the division housing (the inside of the two members (10, 20) ( 40) is installed in combination.
펌프하우징(10)의 내측에는 모터(30)축과 결합되는 임펠러(50)가 설치되어 있으며, 이 임펠러(50)의 밑으로는 디비전하우징(40)이 결합되어 있다.An impeller 50 coupled to the shaft of the motor 30 is installed inside the pump housing 10, and a division housing 40 is coupled to the bottom of the impeller 50.
디비전하우징(40)은 펌프하우징(10)과 모터케이싱(20)의 단턱(25)에 외주면 및 상하면이 밀착된 상태로 결합되어 있어 그 끝단에서는 수직수평방향 어느 쪽으로도 미동되지 않는다.The division housing 40 is coupled to the pump housing 10 and the step 25 of the motor casing 20 in a state in which the outer circumferential surface and the upper and lower surfaces are in close contact with each other, so that they do not slide in any of the vertical horizontal directions.
따라서, 모터(30)의 동작에 의해 펌프하우징(10) 내부의 압력이 높아졌을 경우에도 종래와 같이 디비전하우징(40) 전체가 밀리는 현상이 일어나지 않는다. 아울러, 수직으로 작용하는 압력은 디비전하우징(40) 밑면에 형성된 리브(41)에 의해 단턱(25)에 밀착고정된 끝단으로 전달되므로 수직방향으로의 변위량도 작아지게 된다. 그러므로, 디비전하우징(40)과 메카니칼 씰(60)의 밀착도가 크게 저하되지 않아 펌프하우징(10)을 순환하는 온수가 모터(30)쪽으로 누수되는 것을 차단할 수 있다.Therefore, even when the pressure inside the pump housing 10 is increased by the operation of the motor 30, the phenomenon in which the entire division housing 40 is not pushed as in the related art does not occur. In addition, since the pressure acting vertically is transmitted to the end fixed in close contact with the step 25 by the ribs 41 formed on the bottom of the division housing 40, the displacement amount in the vertical direction is also reduced. Therefore, the adhesion between the division housing 40 and the mechanical seal 60 is not significantly reduced, and thus hot water circulating in the pump housing 10 can be prevented from leaking toward the motor 30.
한편, 모터케이싱(20)의 외주면에는 통풍구(21)가 형성되어 있어 공기의 순환이 자유롭게 이루어는데, 모터(30)가 구동되면 엔드링(31)의 회전에 의해 이들 공기가 모터(30) 내측으로도 순환이 이루어져 모터(30)를 냉각시킨다.On the other hand, the outer circumferential surface of the motor casing 20 is formed with a vent 21 is free to circulate the air, when the motor 30 is driven by the rotation of the end ring 31 these air is inside the motor 30 The circulation is also made to cool the motor (30).
이상에서 설명한 바와 같이 본 고안에 따르면, 디비전하우징을 순환펌프 내측에 안착시킴으로서 외부충격에 의해 디비전하우징이 파손되는 것을 방지하고 수압에 의한 디비전하우징의 변형정도를 작게 하여 모터부로 누수되는 것을 방지하는 효과가 있다.As described above, according to the present invention, the division housing is seated inside the circulation pump, thereby preventing the division housing from being damaged by external shock and reducing the deformation of the division housing due to water pressure, thereby preventing leakage to the motor unit. There is.
