Servo Hydraulic and Pneumatic Drive
2011Among the various drives available, the hydraulic drive ranks at the forefront in terms of application history. The history of hydraulic power dated to the beginning of civilization, where artefacts show the applications of water turbines in power generation (Wikander, Handbook of Ancient Water Technology: Technology and Change in History, Brill ...

Hydraulic drives in wind-power systems
Russian Engineering Research, 2008Choke regulation of the shaft speed in a hydraulic motor connected to an electrogenerator is considered on the basis of a mathematical model, with a view to stabilizing the speed. Linearization of the basic nonlinearities permits identification of the capabilities of the given drive, which may be used as a braking mechanism when the windmill turns at ...

Publisher Summary This chapter presents an overview of hydraulic drives. The pure hydraulic drives with infinitely variable speeds have a lower efficiency than hydraulic drives incorporating a mechanical gear transmission. The limiting speed (rev/min) of hydraulic drives is determined by the oil leakage and the degree of filling of the suction volume.

Ruling Engine with Hydraulic Drive
Applied Optics, 1965The carriage of a ruling engine is driven by a hydraulic system servo-controlled by an optical interferometer, so that the position of the carriage is determined in terms of the wavelength of light. The arrangement is free from the errors of the conventional lead-screw system and is far cheaper to construct.
