일반적으로 난방시스템은 제1도와 같이 보일러(1)에서 가열된 고온수는 공급관(2)단부의 분배관(3a)을 통해 각 난방실(4)의 방열관(5)으로 보내지고 상기 난방실(4)의 방열관(5)에서 고온수가 갖고있는 열을 방열하므로써 난방이 이뤄지게 된다.In general, in the heating system, the hot water heated in the boiler 1 is sent to the heat dissipation pipe 5 of each heating chamber 4 through the distribution pipe 3a at the end of the supply pipe 2 as shown in FIG. The heat is achieved by radiating the heat possessed by the high temperature water in the heat radiating tube 5 of (4).

상기 고온수가 방열하여 냉각된 저온수는 환수관(6) 선단의 분배관(3b)에 의해 각 난방실(4)의 방열관(5)으로 부터 환수관(6)으로 도아지고 환수관(6)의 단부에 설치된 순환펌프(7)에 의해 보일러(1)내로 환수되어 계속 순환토록 되어있다.The cold water cooled by radiating the high temperature water is led from the heat radiating tube 5 of each heating room 4 to the return tube 6 by the distribution tube 3b at the tip of the return tube 6 and returning the return tube 6 It is returned to the boiler 1 by the circulation pump 7 provided at the end of the c), and is continuously circulated.

상기 순환펌프(7)는 보일러(1)로부터 공급관(2), 난방실(4)의 방열관(5) 및 환수관(6)내에 흐로는 난방수를 원활하게 강제순환 시키는 것이며, 고온의 난방수에 의한 손상방지를 위해 통상 환수관(6)축에 설치사용된다.The circulation pump 7 smoothly circulates the heating water flowing from the boiler 1 into the supply pipe 2, the heat dissipation pipe 5 of the heating chamber 4, and the return pipe 6, and the high temperature heating. In order to prevent damage by water, it is usually installed on the shaft of the return pipe (6).

상기 순환펌프(7)는 모우터 케이싱(100)과 회전자조립체(200) 및 유로구조체(300A)로 구성되는태, 상기 모우터 케이싱(100)과 유로구조체(300A)는 다수의 불트에 의해 결합조립되고 상기 회전자 조립체(200) 모우터케이싱(100)과 유로구조체(300A)사이에서 회전가능케 축결합되어 진다.The circulation pump 7 is composed of a motor casing 100, a rotor assembly 200, and a flow path structure 300A, and the motor casing 100 and the flow path structure 300A are formed by a plurality of bolts. Coupling is assembled and rotatably coupled between the rotor assembly 200 motor casing 100 and the flow path structure (300A).

상기 모우터 케이싱(100)내에는 여자철심(도시하지 않음)과 여자코일(110) 및 시동영구자석(120)이 절연수지(130)와 함께 일체로 내장되고 그 상부에 덮개(140)가 씌워져 있다.In the motor casing 100, a female iron core (not shown), a female coil 110, and a starting permanent magnet 120 are integrally integrated with the insulating resin 130 and a cover 140 is covered thereon. have.

상기 회전자 조립체(200)는 중공의 회전자(210), 회전자고정패킹(220) 중공의 임펠러(230) 및 이들이 삽입 결합되는 중공의 저어널 베어링(Journal bearing) (240)으로 구성된다.The rotor assembly 200 is composed of a hollow rotor 210, a rotor fixing packing 220 hollow impeller 230 and a hollow journal bearing (240) to which they are inserted and coupled.

상기 유로구조체(300A)는 유입구(333A)와 배출구(337A)가 형성되고 상기 모우터케이싱(100)과 환수관(6)의 플랜지와의 결합조립을 위한 플랜지(336A)(360)를 갖는 유로케이싱(310A)과, 상기 회전자 조립체(200)를지지하고 난방수를 사방으로 분산시키는 유로몸체(370)로 구성된다.The flow path structure 300A has an inlet 333A and an outlet 337A and a flow path having flanges 336A and 360 for assembling and assembling the flange of the motor casing 100 and the return pipe 6. A casing 310A and a flow path body 370 supporting the rotor assembly 200 and dispersing the heating water in all directions.

상기 분배관(3b)은 주물로된 것으로서 제3도와 같이 환수관(6)과 각난방실(4)의 방열관(5)을 연결하고 이물질 찌꺼기를 제거하기 위해 드레인관(8)이 연결되는 다수의 나사홈(31)(32)(33)이 형성되어 있다.The distribution pipe (3b) is made of a casting as shown in Figure 3 is connected to the heat pipe (6) and the heat pipe (5) of the heating chamber (4) and the drain pipe (8) is connected to remove the debris A plurality of screw grooves 31, 32, 33 are formed.

Since the formed casting distribution pipe 3b is separately formed, two flange joints and four valves are required.

또한, 분배관(3b)과 복수의 밸브연결을 위해서는 방열관(5)과 환수관(6)에 수나사가공을 하고 각각 밴도(BAND)를 삽입체결하여야 하므로 시공작업및 시공시간의 과다로 시공이 까다롭고 많은 자제비가 소요되는 것이었다.In addition, in order to connect the distribution pipe (3b) and the plurality of valves, the male screw must be threaded into the heat dissipation pipe (5) and the return pipe (6), and a bando (BAND) must be inserted and fastened, respectively. This was tricky and costly.

특히, 시공시 순환펌프(7)와 분배관(3b)이 직렬로 연결시공되어야 하므로 협소한 공간에서는 도저히 시공이 곤란한 것이었다.In particular, since the construction of the circulation pump (7) and the distribution pipe (3b) must be connected in series, it was difficult to install in a narrow space.

본 고안은 상기한 바와같은 종래의 제반문제점을 해결할수 있도록 분배관이 일체로된 순환펌프를 마련하므로서 협소한 공간에서도 시공이 용이하게 되고 플랜지이음과 복수의 밴드가 삭감되어 자재비가 경감되는 난방시스템용 순환펌프를 제공함에 그 목적이 있는 것이다.The present invention provides a circulation pump in which the distribution pipe is integrated to solve the conventional problems as described above, so that the construction is easy even in a narrow space, and the flange joint and the plurality of bands are reduced to reduce the material cost. The purpose is to provide a circulation pump.

상기 목적을 달성하기 위하여 본 고안은 모우터 케이싱, 회전자조립체 및 분배관겸 유로구조체로된 난방시스템용 순환펌프를 마련함에 의한다. 이하에서 본 고안을 첨부된 도면에 의거 더욱 상세하게 설명하면 다음과 같다.The present invention is to provide a circulation pump for a heating system of the motor casing, rotor assembly and distribution pipe and flow path structure to achieve the above object. Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

즉, 본 고안은 제4도내지 제6도에 도시된 바와같이 순환펌프가 공지의 모우터 케이싱(100)과 회전자조립체(200)에 분배관겸 유로구조체(300)가 결합조립된 구성으로 된다.That is, the present invention has a configuration in which the circulation pump is coupled and assembled to the well-known motor casing 100 and the rotor assembly 200 as shown in FIGS. 4 to 6. do.

상기 모우터 케이싱(100)은 하방중앙에 회전자(210)를 수용토록 회전축(150)과 회전자 수납홀(101)이 마련되고 분배관겸 유로구조체(300)에 결합조립을 위해 복수의 블트공이 천설된 플랜지(102)가 형성되어 있다.The motor casing 100 is provided with a rotating shaft 150 and a rotor accommodating hole 101 to accommodate the rotor 210 at a lower center thereof, and a plurality of blits for assembling and assembling the distribution pipe and the flow path structure 300. The flange 102 in which the ball was laid is formed.

상기 회전자 조립체(200)는 회전자(210)의 중공부를 통하여 저어널 베어링(240)을 삽입하고 회전자(210) 상단부에 형성된 요홈(211)에 맞추어 저어널베어링(240)의 일단부를 펀칭결함시켜 회전자(210)와 저어널 베어링(240)을 견고하게 맞물림 시킨 다음, 회전자(210) 하단부에 접속되게 플라스틱으로된 회전자고정패킹(220)을억지꺼워 맞춤으로 저어널 베어링(240)에 결합시키고 임펠러(230)를 견고하게 결착시킴으로서 조립되게 된다.The rotor assembly 200 inserts the journal bearing 240 through the hollow portion of the rotor 210 and punches one end of the journal bearing 240 in accordance with the groove 211 formed at the upper end of the rotor 210. The rotor 210 and the journal bearing 240 are firmly engaged with each other, and then the rotor fixing packing 220 made of plastic to be connected to the lower end of the rotor 210 is pressed into the journal bearing 240. ) To be assembled by firmly binding the impeller 230.
