Abstract

PURPOSE: To prevent accidents due to the deflection of a shaft, by connecting an impeller and a rotor of a motor in shapes that are adjoined on the same shaft while arranging a bearing portion of the shaft along the axial direction in space at the rotary inner diameter side of the rotor.
CONSTITUTION: The rotary portions of a motor 1 and a pump 2 are installed in shapes that are adjoined on the same rotary main shaft 11, and a low pressure chamber 79 is formed between a ring 78 concentrically mounted to the rotary main shaft 11 on the rear of an impeller 7 in a projecting shape and a rotor plate 23 of the motor 2 adjacently disposed to the impeller 7. The motor 2 consists of a stator 22 and a rotor 21 that are each covered with anticorrosive sheets 26, and the rotary main shaft 11 is supported in a revolution-free shape by means of a radial bearing 41 arranged in the axial direction in space at the inner diameter side of the rotor 21 and a thrust bearing 42.
