Description
【０００７】
加えて、遠心力によりインペラ１０１の外側へ飛ばされた液体等が回転により吸い込まれた気体や液体が保持部材１０２の裏側、すなわち平面部１０２ａのモータ駆動部側へ入り込む、この入り込んだ液体等の圧力を保持部材１０２の平面部１０２ａが受けるため、上述した推力がより強力なものとなる（図６の１点鎖線参照）。このため、回転軸を支持する軸受け、特にスラスト軸受けに多大な荷重がかかり軸受けを破損するおそれがある。また、多大な荷重を受けながら回転軸が回転するため、軸受け部分に発生する熱が異常に高くなり、軸受けを格納している軸受けホルダーがその摩擦熱によって溶けてしまうという問題が生じる。[0007]
In addition, the liquid or the like that is blown out to the outside of the impeller 101 by the centrifugal force is absorbed by the rotation, and the gas or liquid absorbed by rotation enters the back side of the holding member 102, ie, the motor drive portion side of the flat portion 102a. Since the flat portion 102a of the holding member 102 receives the pressure, the above-described thrust becomes stronger (see the dashed-dotted line in FIG. 6). For this reason, a large load may be applied to the bearing that supports the rotating shaft, in particular the thrust bearing, and the bearing may be damaged. In addition, since the rotary shaft rotates while receiving a large load, the heat generated at the bearing portion becomes abnormally high, which causes a problem that the bearing holder storing the bearing is melted by the frictional heat.
