CHINA NATIONAL STANDARD BLADDER ACCUMULATOR
INTRODUCTION
Inner space of accumulator is divided into two parts by bladder: nitrogen is fi-
lled in bladder and hydraulic oil is filled the bladder. When hydraulic oil is pressed
into accumulator by hydraulic valve, bladder deform by the pressure, volume of g-
as decreases with the increasing of pressure. Hydraulic oil is stored gradually. If
hydraulic system need hydraulic oil to work, accumulator discharge the hydraulic
oil and compensate the system energy.
