In the positioned state, the assembled flange 130 is moved in a direction close to the pump housing.

위와 같이 조립형 플랜지(130)의 이동에 의하여 제2 체결부(131)는 제1 체결부(122)로 삽입되고, 제1 체결부(122)에 삽입된 채로 제1 체결부(122)를 따라 이동하게 되며, 결국에는 제1 체결부(122)으로부터 이탈하여 걸림턱(121)의 배면(121b)에 위치하게 되며, 이로써 조립형 플랜지(130)의 가조립이 이루어지게 된다.(도 3 참조)As described above, the second fastening portion 131 is inserted into the first fastening portion 122 by the movement of the assembled flange 130, and the first fastening portion 122 is inserted into the first fastening portion 122. It is moved along, and eventually separated from the first fastening portion 122 is located on the rear surface (121b) of the locking jaw 121, whereby the prefabricated assembly of the assembled flange 130 is made (see Fig. 3). )

상기와 같이 조립형 플랜지(130)의 가조립이 이루어진 상태에서 조립형 플랜지(130)를 플랜지 조립부(120)를 기준으로 회전시켜 제2 체결부(131)가 제1 체결부(122)와 어긋나도록 함으로써 조립형 플랜지(130)의 완전한 조립이 이루어지게 된다.As described above, in the state in which the assembled flange 130 is temporarily assembled, the assembled flange 130 is rotated based on the flange assembly 120 to displace the second fastening portion 131 from the first fastening portion 122. By doing so, the complete assembly of the assembled flange 130 is made.

한편 조립형 플랜지(130)의 조립이 완료되면, 흡입 배관(P:도 1에 도시됨)에 형성된 플랜지(F:도 1에 도시됨)와 조립형 플랜지(130)를 볼팅 체결함으로써 펌프와 배관의 연결작업을 완료하게 된다.
On the other hand, when the assembly of the assembled flange 130 is completed, the pump and the piping by bolting the flange (F: shown in Figure 1) and the assembled flange 130 formed on the suction pipe (P: shown in Figure 1) This completes the connection work.

상술한 바와 같이, 본 발명에 따른 펌프는 펌프 하우징(110)의 제작시 플랜지를 일체형으로 형성하지 않고 별도로 제조된 조립형 플랜지를 펌프 하우징에 형성된 플랜지 조립부에 조립하여 배관과의 연결작업을 실시하도록 함으로서, 종래의 일반적인 펌프 하우징(110) 보다 손쉽게 펌프 하우징(110)을 제조할 수 있으며, 특히 스테인레스 스틸을 이용하여 펌프 하우징(110)을 주조하는 경우에도 펌프 하우징(110)의 안정적인 제조가 가능하게 되는 이점이 있다.As described above, the pump according to the present invention does not form a flange integrally when manufacturing the pump housing 110, but assembled separately assembled assembly flange to the flange assembly formed in the pump housing to perform the connection work with the pipe. By doing so, it is possible to manufacture the pump housing 110 more easily than the conventional pump housing 110, in particular, even in the case of casting the pump housing 110 using stainless steel, it is possible to manufacture a stable pump housing 110 There is an advantage to doing this.

물론 플랜지 조립부(120)도 기존 플랜지와 마찬가지로 흡입구(111)나 토출구(112)로부터 돌출된 구조를 갖고 있으나, 플랜지 조립부(120)는 기존 플랜지 보다 낮은 높이로 돌출되므로, 펌프 하우징의 주조시 보다 용이하게 형성될 수 있다.
Of course, the flange assembly 120 also has a structure protruding from the inlet 111 or the outlet 112, like the existing flange, but the flange assembly 120 is projected to a lower height than the existing flange, when casting the pump housing It can be formed more easily.

본 발명은 상술한 특정의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.
It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
