摘要： A fluid rotating apparatus of a positive displacement 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 suction chamber and a discharge chamber in the housing respectively communicating with the suction port and the discharge port, a plurality of motors for individually rotating the rotors, and a detecting device for detecting rotating angles and rotating numbers of the motors. In the apparatus, a fluid is sucked and discharged due to capacity change of a space defined by the rotors and the housing through synchronous control of the rotation of the plurality of motors by a signal from the detecting device. The housing has a communicating path with a flow control device to make an upstream side communicate with a downstream side of the apparatus when the rotational numbers of the rotors are less than a predetermined value. A method of controlling the apparatus includes the steps of opening the communicating path by operating the flow control device to cause the upstream side to communicate with the downstream side of the apparatus when the rotational numbers of the rotors are less than a predetermined value, and closing the communicating path by operating the flow control device when the rotational numbers of the rotors are not less than a predetermined value.

摘要： 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.
