ENERGY SAVING IN HYDRAULIC DRIVES

COLLECTION OF SCIENTIFIC PAPERS
The article discusses various ways to save energy in the hydraulic drive. To do this, you need to study various methods energy saving, including throttling, changes in working volumes pumps and motors, the use of an adjustable pump and throttle flow regulator, as well as study methods of energy recovery in hydraulic drives.

Adaptive Hydraulic Drive of Manipulator

Applied Mechanics and Materials, 2016
At present in manipulators the hydraulic drives with one degree of freedom are used. Such drive provides single-valued function of constraint between input and output links motion. However for overcoming of variable force of resistance it is necessary to use the variable transfer ratio between input and output links. The adjustable drive should contain

Digital Hydraulic Winch Drives

BATH/ASME 2018 Symposium on Fluid Power and Motion Control, 2018
This paper presents the planned use of digital displacement high torque low speed motors to drive large winches in off-shore and maritime applications. The digital displacement technology uses forced actuation of high- and low pressure valves for each cylinder chamber, i.e.

Clinker cooler hydraulic drives

Cement Industry Technical Conference, 2003. Conference Record. IEEE-IAS/PCA 2003, 2003
For many years modifications to grate cooler technology have continuously developed. Many of the grate coolers supplied for the cement industry over the last 50 years include hydraulic drives. Continuous developments for the clinker cooler hydraulic drive have achieved a considerable improvement of operation, reliability and capacity. The following two

Hydraulic Drives With High Efficiency

Fluid Power Systems and Technology, 1995
Abstract Starting with the different methods of controlling hydraulic power this paper analyses the possibilities of saving energy. It turns out that the two fundamentally different types of displacement control avoid purposely induced throttle losses. New developments in this field are presented.
