본 고안은 고정자의 수밀유지를 위해 사용되는 캔을 엔드쉴드의 역할을 겸하도록 일체로 형성하여 기밀효과를 더욱 향상시켜주도록 한 캔타입 모터펌프의 기밀장치에 관한 것이다.The present invention relates to an airtight device of a can type motor pump, which is formed to integrally form a can used for watertightness of a stator to serve as an end shield to further improve an airtight effect.
종래에 사용되었던 캔타입 모터펌프의 기밀장치는 첨부도면 제3도 및 제4도에 도시된 바와같은 형태로서, 먼저 제3도의 형태를 설명하면 엔드쉴드(10)와 캔(11)이 분리되어 있는 타입으로 엔드쉴드(10)가 케이싱(12)과 모터부(2)를 분리시키는 칸막이 역할을 수행하면서 유체가 모터부(2)로 유입되는 것을 막아주고, 캔(11)은 원통형 박판으로 양단에 0링(13)을 삽입하여 고정자부(1)로 유체가 누설되는 현상을 막아주도록 하였다.The airtight device of the can type motor pump, which has been used in the related art, has a shape as shown in FIGS. 3 and 4 of the accompanying drawings. First, the shape of FIG. 3 will be described. End shield 10 serves as a partition to separate the casing 12 and the motor unit 2 to prevent the fluid from flowing into the motor unit 2, the can 11 is a cylindrical thin plate at both ends The 0 ring 13 was inserted into the stator 1 to prevent the fluid from leaking into the stator part 1.
이때, 앤드쉬드(10)는 베아링을 지지하는 베아링 하우징 역할과 함께 반부하측 슬리이브베아링의 윤활을 위하여 일부 허용된 틈새나 구멍을 통해 유체의 유입을 허용하도록 하고 있다.At this time, the end 10 is to allow the inflow of the fluid through a portion of the gap or hole allowed for the lubrication of the half-load sleeve bearing with the bearing housing to support the bearing.
또한, 제4도와 같은 형태는 캔(14)이 엔드쉴드의 역할을 일부겸하면서 베아링의 지지를 위하여 또다른 엔드쉴드(15)를 형성해 주도록 한 것이다.In addition, the shape as shown in FIG. 4 allows the can 14 to form another end shield 15 to support the bearing while also serving as an end shield.
여기서도 마찬가지로 케이싱과 엔드쉴드의 역할을 하는 캔(14)에 가스킷트를 삽입하여 유체의 외부 누설을 방지하도록 하고, 반부하측에는 전술한 바와같이 베아링 하우징을 별도로 분리하지 않고 캔(14)의 끝단부를 절곡하여 그 내부에 캔을 접용접하여줌에 따라 베아링을 지지하도록 하였다.Here too, a gasket is inserted into the can 14 serving as a casing and an end shield to prevent external leakage of the fluid, and as described above, at the half-load side, the end portion of the can 14 can be removed without separately removing the bearing housing. It was bent to support the bearings by welding the cans therein.
그러나 상기한 바와같은 종래장치는, 먼저 제3도와 같은 형태는 박판캔의 양단에 고무링을 삽입하여 유체누설을 막아주도록 하였으나 운전시 회전자의 진동과 압력의 변화등에 의하여 고무링 압축공간에 간극이 발생함과 동시에 모세관현상이 일어나 고정자축으로 유체가 누설되는 현상이 발생하였고, 엔드쉴드와 캔이 분리되어 있어 제조공정이 많아지며, 이에따라 원가상승 요인도 되었다.However, in the conventional apparatus as described above, in the form of FIG. As a result of this, capillary phenomenon occurred and fluid leaked to the stator shaft, and the end shield and the can were separated, thus increasing the manufacturing process, and thus, the cost increase factor.
또한, 제4도와 같은 형태는 캔의 두께가 두터운데 비하여 곡선부가 많기 때문에 캔의 제조공정이 복잡하고, 반부하측 베아링 하우징의 동심도 불량에 의하여 불균일한 공극을 발생시킬 위험이 많았으며, 부하측 베아링 하우징 역할만을 위한 엔드쉴드를 별도로 제작해 주어야 하는 공정상의 번거로움이 많았다.In addition, as shown in FIG. 4, since the can has a large thickness, the can has a large number of curved portions, and thus, the manufacturing process of the can is complicated. There was a lot of trouble in the process of having to make an end shield for a role only.
본 고안은 상기와 같이 종래장치에 대한 각각의 문제점을 해소하기 위한 것으로서, 캔타입 모터펌프의 기밀장치를 개선하여 엔드쉴드와 캔을 일체화시킨 간단한 구조로서 기밀효과를 더욱 향상시켜 주도록 한 것이다.The present invention is to solve the problems of the conventional device as described above, to improve the airtightness effect as a simple structure integrating the end shield and the can by improving the airtightness device of the can type motor pump.
상기 목적을 달성하기 위한 본 고안에 따르면, 고정자부(1)의 유체누설방지와 함께 모터부(2)의 기밀유지를 위한 캔타입 펌프의 캔(3)을 부하측으로 엔드쉴드와 일체형을 이루도록 함과 동시에 베아링 하우징 부위로는 다수의 유체통로(3a)를 형성하고, 반부하측으로는 나사부(3b)를 일체로 형성하여서 된 것이다.According to the present invention for achieving the above object, the can (3) of the can type pump for the airtight maintenance of the motor unit (2) with the fluid leakage prevention of the stator (1) to form an integral with the end shield to the load side At the same time, a plurality of fluid passages 3a are formed in the bearing housing portion, and the threaded portions 3b are integrally formed on the half load side.
이와같이 된 본 고안은 첨부도면과 함께 더욱 상세히 설명하면 다음과 같다.The present invention has been described in more detail with the accompanying drawings as follows.
제1도는 본 고안을 갖는 캔타입 모터펌프의 조립상태를 나타낸 단면도로서, 하나의 일체화된 캔(3)을 통해 엔드쉴드의 기능과 함께 캔의 기능을 동시에 수행하도록 한것이다.Figure 1 is a cross-sectional view showing the assembly state of the can type motor pump having the present invention, it is to perform the function of the can simultaneously with the function of the end shield through one integrated can (3).
따라서 캔(3)의 부하측에는 엔드쉴드부가 일체로 형성되어 있어 유체가 모터부측으로 유입되는 것을 막아주게 되고, 캔(3)의 베아링 하우징 부위측으로는 제2도와 같이 원주면상에 다수의 유체통로(3a)가 형성되어 있기 때문에 이 유체통로(3a)를 통해 일부 유체가 베아링부로 유입되는 것을 허용해줌에 따라 베아링부의 윤활기능을 도와주도록 하였다.Accordingly, the end shield portion is integrally formed on the load side of the can 3 to prevent the fluid from flowing into the motor portion, and the plurality of fluid passages on the circumferential surface of the can housing 3 as shown in FIG. Since 3a) is formed, some fluid is allowed to flow into the bearing portion through the fluid passage 3a, thereby assisting the lubrication function of the bearing portion.
또한, 반부하측인 캔(3)의 끝단부로는 나사부(3b)가 형성되어 있어 베아링 하우징에 형성된 수나사부로 캔(3)이 체결됨에 따라 조립이 이루어지게 된다.In addition, the thread portion 3b is formed at the end of the can 3 on the half-load side, and the assembly is performed as the can 3 is fastened to the male screw portion formed in the bearing housing.
캔(3)의 조리시에는 제2도와 같이 베아링 하우징의 수나사골면에 라이너(4)를 부착하여 이를 통해 캔(3)의 나사부(3b)가 끼워 지도록 함에 따라 라이너(4)를 사용하지 않는 경우보다 더욱더 밀봉기능을 향상시켜 주도록 하는 것이 바람직하다.When the can 3 is not cooked, the liner 4 is attached to the male threaded surface of the bearing housing as shown in FIG. 2 so that the threaded portion 3b of the can 3 is fitted therein so that the liner 4 is not used. It is desirable to further improve the sealing function.
또한, 캔(3)에 형성되는 나사부(3b)는 약간의 데이터를 지하도록 형성해줌에 따라 텡퍼의 경사각도에 의해 조립후 보다나은 밀봉능력을 갖도록 하였다.In addition, the screw portion 3b formed in the can 3 is formed to support some data, and thus has a better sealing ability after assembly by the inclination angle of the wafer.
이때, 캔(3)에 형성되는 나사부(3b)는 제2도에 도시된 바와 같은 둥근형 이외에도 성형이 가능한 삼각형, 사각형, 톱니형 등의 여러가지 형태로 변형 실시해주는 것도 가능한 것이다.At this time, the screw portion 3b formed in the can 3 may be modified in various forms such as triangle, square, and sawtooth, which can be molded in addition to the rounded shape as shown in FIG.
이와같이 본 고안은 엔드쉴드와 캔을 하나의 일체형으로 형성해줌에 따라 간단한 구조로서 1회공정에 의한 제작이 간편함과 동시에 작업성도 향상되며, 캔이 밀봉을 요하는 접촉부위들과 강력한 밀착접속이 이루지면서 종래에 비하여 향상된 수밀 유지효과를 갖도록 해주게 된다.As such, the present invention forms an end shield and a can into a single body, which is simple in structure and easy to work in a single process, and improves workability. While it is to have an improved watertight retention effect compared to the prior art.
