摘要： PROBLEM TO BE SOLVED: To provide an operation method that prevents a screw and a drive unit of the screw from being deteriorated in a twin screw extruder, thereby extending the life thereof.SOLUTION: In a twin screw extruder (1), a rotational speed of a screw (3) is changed to actively reduce the amplitude of torque acted on the screw. Specifically, as a preliminary process, the screw (3) is operated for a predetermined time at a constant rotational speed to detect torque or a predetermined physical quantity related to the torque. Then, a torque variation function changing according to a rotating position of the screw (3) is determined on the basis of the detected torque or the physical quantity. A screw rotational speed is controlled by periodically changing a target rotational speed of the screw (3) such that the torque amplitude is reduced, on the basis of the torque variation function, in an operation process.

摘要： PROBLEM TO BE SOLVED: To provide a hydrogen compressing device of such a structure that a cushion tank is installed between a hydrogen compression part and a hydrogen generating device, capable of supplying high-pressure hydrogen stably by monitoring the internal pressure of the cushion tank and making automatic start and stop of the operation of the hydrogen compression part.
SOLUTION: The hydrogen compressing device is structured so that the cushion tank 61 is installed between the hydrogen generating device 60 and the hydrogen compression part 68, whereby the hydrogen gas 60a supplied from the hydrogen generating device 60 is allowed to stagnate once in the cushion tank 61 until the set suction pressure of the hydrogen compression part 68 is attained.
