辅助装置功能：创造必要条件，确保液压系统可靠、稳定、持久 辅助装置分类:蓄能器、滤油器、油箱、压力计、压力计开关、热交换器等 蓄能器的功用：储存能量，必要时释放 一、短时间内大量供油（协助泵供油、作应急动力源） 二、吸收液压冲击和压力脉动 三、维持系统压力（保压补漏） 蓄能器的类型及特点 按结构形式分为重锤式、弹簧式、充气式（非隔离式、隔离式（活塞式、气囊式、隔膜式） 重锤式蓄能器工作原理 重物势能油压 释放能量 重锤式蓄能器性能特点：结构简单，容量大，压力稳定，但结构尺寸大而笨重，运动惯性大，反应不灵敏，易漏油，有摩擦损失。
常用于蓄能 弹簧式蓄能器工作原理 弹簧能量压力 储油 弹簧能量>油压 释放能量 弹簧式蓄能器性能特点：结构简单，反应尚还灵敏，但容量小，易内泄并有压力损失，不适于高压和高频动作的场合一般可用于小容量、低压系统，用作蓄能和缓冲 充气式蓄能器 （1）气瓶式蓄能器（直接接触式蓄能器） (2)活塞式蓄能器 (3)气囊式蓄能器 气瓶式蓄能器工作原理 气压油压 释放能量 气瓶式蓄能器性能特点：容量大，但由于气体混入油液中，影响系统工作的平稳性，而且耗气量大，需经常补气，仅适用于中、低压大流量系统。
活塞式蓄能器工作原理 气压油压 释放能量 活塞式蓄能器性能特点：结构简单，工作可靠，安装容易，维修方便，寿命长，但因有摩擦，反应不灵敏，容量较小一般用于蓄能 气囊式蓄能器工作原理 气压油压 释放能量 气囊式蓄能器性能特点：重量轻、尺寸小、安装容易、维护方便、惯性小、反应灵敏，但气囊制造困难。
既可用于蓄能、又可用于缓和冲击、吸收脉动 蓄能器容量计算 容量是选用蓄能器的依据，其计算视用途而异，现以气囊式为例加以说明 作蓄能使用时蓄能器容量的计算 ∵ 蓄能器存储和释放的压力油容量和气囊中气体体积的变化量相等，而气体状态变化应符合玻义耳气体定律 ∴ p0V0=p1V1=p2V2 △V=V2-V1 1/n1/n V0=△V(p2/p0)/[1-(p2/p0)] 一般取p0=（0、8∽0、85）p 2 储能器在吸收冲击时的容量计算 吸收压力脉动时蓄能器的容量计算 V0=Vi/0、6k 使用和安装蓄能器 1 充气式蓄能器中应使用惰性气体（一般为氮气） 2 蓄能器一般应垂直安装，油口向下。
3 必须用支架或支板将蓄能器固定，且便于检查、维修的位置，并远离热源 4 用作降低噪声、吸收脉动和冲击的蓄能 器应尽可能靠近振源 5 蓄能器与管路之间应安装截止阀，供充气或检修时用，与液压泵之间应安装单向阀，防止油液倒流保护泵与系统。
6 搬运和拆装时应排出压缩气体—注意安全 90-L-075-KP-1-NN-80-L-4-S1-D-03-GBA-35-35-24 90L075KP1NN80L4S1D03GBA353524 90-L-075-KP-1-NN-80-L-4-S1-E-02-GBA-29-29-24 90L075KP1NN80L4S1E02GBA292924
