Introduction Accumulators and Accessories Accumulators provide a means of regulating the performance of a hydraulic system. They are suitable for storing energy under pressure, absorbing hydraulic shock, dampening pump pulsation and fl ow fl uctuations. Bladder or diaphragm accumulators provide excellent gas and fl uid separation ensuring dependable performance, maximum effi ciency, and long service life. Why use an Accumulator? • Improves your system effi ciency • Accepted world wide • Supplements your pump fl ow • High/ low temperature tolerance • Supplies extra power in an emergency • Extremely safe (cannot be disassembled under pressure) • Compensates for any system leakage • Quick response • Absorbs hydraulic shocks • Wide range of compounds for a variety of fl uids Accumulator Function The design of the Stauff accumulator makes use of the difference in the compressibility between a gas (nitrogen) and a liquid (hydraulic fl uids). The bladder contained in the shell is pre-charged with nitrogen gas to a pressure determined by the system pressure. After pre-charging, the work can be split into three steps. Step 1. When the hydraulic fl uid enters the accumulator, the nitrogen contained in the bladder is compressed and its pressure is increased. Step 2. The compression of the bladder stops when the pressure of the fl uid and nitrogen are equal (balanced). During this step the bladder is not subject to any abnormal mechanical stress. Step 3. On demand, as system pressure falls, the accumulator’s stored fl uid is returned to the system under pressure applied by the compressed nitrogen. On completion of the hydraulic system functions, the accumulator reverts to step 1. 3
