Fluid conditioners and hydraulic accumulators

2010
A hydraulic system does not only consist of pumps, motors, valves and hydraulic piping. This chapter deals with the parts in the hydraulic system that maintain the condition of the hydraulic fluid. A proper design for these sub systems is very important for the lifetime of the hydraulic system.

Hydraulic accumulator-motor-generator energy regeneration system for a hybrid hydraulic excavator

Chinese Journal of Mechanical Engineering, 2012
Though the traditional energy regeneration system(ERS) which used a hydraulic motor and a generator in hybrid excavators can regenerate part of the energy, the power of the motor and the generator should be larger and the time for regenerating energy is so short.

Design optimization of a hydraulic flywheel accumulator for a hydraulic hybrid vehicle

International Journal of Fluid Power, 2015
The hydraulic flywheel accumulator is a novel energy storage device that has the potential to overcome major drawbacks of conventional energy storage methods for mobile hydraulic systems. By employing a rotating pressure vessel, the hydraulic flywheel accumulator stores energy in both the hydro-pneumatic domain and the rotating kinetic domain.

Increasing Hydraulic Energy Storage Capacity: Flywheel-Accumulator

International Journal of Fluid Power, 2009
AbstractThe energy storage density of hydraulic accumulators is significantly lower than energy storage devices in other energy domains. As a novel solution to improve the energy density of hydraulic systems, a flywheel-accumulator is presented. Energy is stored in the flywheel-accumulator by compressing a gas, increasing the moment of inertia of the ...

Bellows Accumulators for 8000 PSI Hydraulic Systems

SAE Technical Paper Series, 1985
<div class="htmlview paragraph">A Bellows Hydraulic Accumulator offers superior performance and design advantages when compared with accumulators which use elastomeric seals. By using a metal bellows as the dynamic separator between the gas precharge and the hydraulic fluid, a factory precharged, maintenance free accumulator is achieved.

Constant pressure hydraulic energy storage through a variable area piston hydraulic accumulator

Applied Energy, 2013
Abstract Hydraulic accumulators are used in a variety of applications to minimize the pressure variation in hydraulic circuits and to store energy. Conventional hydraulic accumulators suffer from two major limitations, the hydraulic system pressure varies with the quantity of energy stored and the energy density is significantly lower than other ...
