ABSTRACT:
A fluid rotating apparatus of a positive displacement type pump includes a plurality of rotors accommodated in a housing, a bearing for rotatably supporting the rotors, a suction port and a discharge port formed in the housing, a plurality of motors for individually rotating the rotors, a detector for detecting rotating angles and rotating speeds of the motors, a synchronous controller for controlling rotation of the plurality of motors by a signal from the detector, and a transporting member coaxially provided on one of the rotors and on the upstream side thereof. The transporting member includes a rotary disk rotatable together with the rotor and a fixed disk opposed to the rotary disk fixed to the housing so as to maintain a gap between the rotary disk and the fixed disk. A spiral groove is formed on one of a surface of the rotary disk and an opposing surface of the fixed surface so as to transport one of fluid and gas molecules in a radial direction of the rotor between the rotary disk and the fixed disk. In this manner, fluid (i.e., liquid or gas) molecules are sucked and discharged due to a capacity change of a space defined by the rotors and the housing through synchronous control by the synchronous controller.
