D&D Ricambi Srl: the leader on supply of hydraulic components and systems
hydraulic components for construction, earthmoving, agricultural and industrial machinery
 
 

Hydraulic accumulators
D&D Ricambi Srl offers a complete range of hydropneumatic accumulators, electromechanical and electronic pressure switches, vacuum switches, level gauges for tanks and flow.

Trained and experienced engineers are always available to help customers evaluate and choose the most appropriate instrument. 


The hydropneumatic accumulator is a device that makes it possible, in the hydraulic circuits, a significant energy storage in small spaces. Since liquids are virtually incompressible, therefore unsuitable for energy accumulation, the goal is achieved by exploiting the large compressibility of gases:
A) In a container (the accumulator) is mounted an elastic separator (bag).
B) From an appropriate valve is entered inert gas (nitrogen) in the PO pressure bag. The bag expands occupying the whole inner volume of the VO body accumulator.
C) When the P1 pressure in the circuit exceeds the precharge PO pressure, there is the opening of the liquid valve and the compression of the bag with reduction of the V1 volume.
D) By increasing the pressure of the P2 liquid, there is a reduction of the volume of V2 gas with increase in its pressure in order to balance the pressure of the liquid.
