Abstract

본 발명은 온수를 강제순환시키는 온수순환펌프에 있어서, 샤프트를 지지하여 주는 세라믹베어링에 관한 것으로써, 고정자(8)에 전원이 입력되면 로타(9)가 회전되고 로타(9)가 축설된 샤프트(10)가 회전되면서 임펠러(5)를 회전시켜 유입구(3)를 통해 유입된 온수를 강제순환시켜 유출구(4)로 유출시키도록된 온수순환펌프(1)에서 샤프트(10)를 축설시키는 세라믹베어링(11)(11-1)에 있어서, 세라믹베어링의 내면에 공간부(22)를 형성하여 상·하양단 내면의 연접부(23)(24)가 샤프트(10)에 연접되어지도록 된 것인바, 세라믹베어링과 샤프트와의 접촉면적 즉 습동면적을 감소시켜 마찰저항을 줄여주므로 회전력이 향상되어 펌프의 성능과 효율이 향상되어진다.The present invention relates to a ceramic bearing for supporting a shaft in a hot water circulation pump for forced circulation of hot water, wherein when the power is input to the stator (8), the rotor (9) is rotated and the rotor (9) is built up. Rotating the impeller (5) while rotating (10) is a ceramic for accumulating the shaft (10) in the hot water circulation pump (1) that is forced to circulate the hot water introduced through the inlet (3) to the outlet (4) In the bearings 11 and 11-1, the space portion 22 is formed on the inner surface of the ceramic bearing so that the connecting portions 23 and 24 on the inner surface of the upper and lower ends are connected to the shaft 10. Since the frictional resistance is reduced by reducing the contact area between the Invar and the ceramic bearing and the shaft, that is, the sliding area, the rotational force is improved, which improves the performance and efficiency of the pump.
