Abstract

본 발명은 온수(유체)를 강제 순환시킬 수 있도록 된 온수순환펌프에 관한 것으로서, 모터하우징(30)의 고정자(31)에 전원이 입력되면 샤프트(40)에 축착된 회전자(32)가 그 샤프트(40)와 함께 회전되고, 그 샤프트(40)의 상측에 축착된 임펠러(25)가 모터앤드 쉴드(26)에 의해 분할된 펌프하우징(21)의 임펠러실(24)에서 회전하면서 온수를 강제 순환시키도록 된 것에 있어서, 샤프트(40)가 축설되는 임펠러(25)의 내측저면 중앙에 유입실(25-2)이 구비되도록 만곡형의 돌부(25-3)를 형성하고 그 돌부(25-1)에 복수개의 배출공(25-2)을 등간격으로 통공하는 것과, 사프트가(40)가 축삽되는 모터앤드쉴드(26)에 복수개의 유통공(27)을 통공하는 것과, 상측 베어링(33)이 삽설되는 샤프트(40)의 상측 표면부에 3개의 환상요홈(41)을 각각 요설하되, 상기 환상요홈(41)은 상측 베어링(33)의 상면과 일치되고 그 중앙에 그리고 하단의 아래쪽에 형성하는 것과, 하측베어링(34)의 삽설되는 샤프트(40)의 하측에는 상단선행부가 하측베어링과 일치되도록 나선형유입공(42)을 요설하는 것과, 상기 샤프트(40)의 중앙에 길이 방향으로 상광하협의 안내관로(43)을 통공하여 임펠러(25)의 유입실(25-2)과 베어링홀더(37)의 공간부(36)를 연통 시키되 상단에 요홈(44)을 요설하여 세라믹 볼(45)을 안치시켜서 된 것인바 온수를 강제순환시켜 냉각효과를 향상시키고, 샤프트와 베어링 사이에 수막이 형성되도록 하여 마찰력을 주어 회전력을 향상시키며, 스테이터캔의 내부에 유입된 온수에 함침된 이물질을 강제 배출시키므로 샤프트와 회전자가 고형화되는 것을 방지할 수 있을 뿐만 아니라, 정지시에는 볼이 안내관로를 폐쇄시키므로 온수의 유출없이 용이하게 수리할 수 있다.The present invention relates to a hot water circulation pump capable of forcibly circulating hot water (fluid), and when a power is input to the stator 31 of the motor housing 30, the rotor 32 which is condensed to the shaft 40 is the same. The impeller 25 rotated together with the shaft 40 and condensed on the upper side of the shaft 40 rotates in the impeller chamber 24 of the pump housing 21 divided by the motor and shield 26. In the forced circulation, a curved protrusion 25-3 is formed so that the inflow chamber 25-2 is provided at the center of the inner bottom surface of the impeller 25 on which the shaft 40 is built up, and the protrusion 25 -1) through the plurality of discharge holes 25-2 at equal intervals, through the plurality of distribution holes 27 through the motor end shield 26 into which the shaft 40 is inserted, and the upper bearing Three annular recesses 41 are respectively provided in the upper surface portion of the shaft 40 into which the 33 is inserted, and the annular recesses 41 are upper bearings 33. And the lower part of the shaft 40 in which the lower bearing 34 is inserted, coincide with the upper surface of the lower part of the shaft 40, and the upper leading portion of the lower part of the shaft 40 is arranged so as to coincide with the lower bearing. In the longitudinal direction, the inlet chamber 25-2 of the impeller 25 communicates with the space 36 of the bearing holder 37 by passing through the guide pipe 43 of the upper and lower narrow shafts in the longitudinal direction in the center of the shaft 40. The groove 44 is formed at the top to enclose the ceramic ball 45. The hot water is forced to circulate to improve the cooling effect, and a water film is formed between the shaft and the bearing to give frictional force to improve rotational force. By forcibly discharging foreign substances impregnated in the hot water introduced into the can, the shaft and the rotor can be prevented from solidifying, and when the ball stops, the ball closes the guide line so that the hot water can be easily discharged. Crab can repair.
