Abstract

본 발명은 임펠러유니트를 설치한 샤프트를 지지하는 베어링을 개선하여 샤프트의 전부하를 흡수하는 동시에 샤프트와 베어링사이의 마모 및 고착을 방지하여 성능 및 품질을 향상시키고자 발명한 심정용 수중펌프의 샤프트베어링에 관한 것으로, 하부에 위치되어 전기의 공급에 의하여 구동하는 모터부(10)와; 모터부(10)에 일체로 조립되어 지지되는 펌프베이스(21)와, 모터부(10)의 회전축(11)과 커플링(12)을 일체로 연결되는 샤프트(22)와, 펌프베이스(21)내에 설치되도록 샤프트(22)에 필요한 단수만큼 끼워서 일체로 적층되는 임펠러유니트(23)와, 펌프베이스(21)의 상부에 조립되어 샤프트(22)를 지지하여 주는 펌프헤드(24)와, 펌프헤드(24)에 억지끼워서 샤프트(22)에 걸리는 임펠러유니트(23)의 전부하 및 샤프트흔들림을 잡아주도록 샤프트(22)와 굴대설치되는 베어링(25)으로 펌프부(20)를 구성한 심정용 수중펌프에 있어서, 상기 샤프트(22)의 외주면과 축방향으로 섭접촉되어 슬라이딩 하는 동시에 미세한 모래가 모서리틈새를 통하여 배출되도록 충격흡수가 우수한 우레탄재의 베어링(25)의 내주면을 각면(25a)으로 형성한 것이다.The present invention improves the bearing supporting the shaft on which the impeller unit is installed to absorb the full load of the shaft and at the same time prevents wear and seizure between the shaft and the bearing to improve the performance and quality of the submersible submersible pump shaft It relates to a bearing, the motor unit 10 which is located at the bottom and driven by the supply of electricity; A pump base 21 integrally assembled and supported by the motor unit 10, a shaft 22 which integrally connects the rotary shaft 11 and the coupling 12 of the motor unit 10, and the pump base 21. The impeller unit 23 that is integrally stacked by inserting as many stages as necessary on the shaft 22 to be installed in the shaft 22, the pump head 24 that is assembled to the upper portion of the pump base 21 to support the shaft 22, and the pump Submerged heart for the pump part 20 composed of the shaft 22 and the bearing 25 installed in the mandrel to hold the full load and shaft shaking of the impeller unit 23 caught by the head 24 to the shaft (22) In the pump, the inner circumferential surface of the bearing 25 of urethane material having excellent shock absorption is formed on each surface 25a so as to slid in contact with the outer circumferential surface of the shaft 22 in the axial direction and to discharge fine sand through the edge gap. will be.
