?輔助裝置功能：創造必要條件，確保液壓系統可靠、穩定、持久 輔助裝置分類:蓄能器、濾油器、油箱、壓力計、壓力計開關、熱交換器等 蓄能器的功用：儲存能量，必要時釋放 一、短時間內大量供油（協助泵供油、作應急動力源） 二、吸收液壓沖擊和壓力脈動 三、維持系統壓力（保壓補漏） 蓄能器的類型及特點 按結構形式分為重錘式、彈簧式、充氣式（非隔離式、隔離式（活塞式、氣囊式、隔膜式） 重錘式蓄能器工作原理 重物勢能油壓 釋放能量 重錘式蓄能器性能特點：結構簡單，容量大，壓力穩定，但結構尺寸大而笨重，運動慣性大，反應不靈敏，易漏油，有摩擦損失。
常用于蓄能 彈簧式蓄能器工作原理 彈簧能量壓力 儲油 彈簧能量>油壓 釋放能量 彈簧式蓄能器性能特點：結構簡單，反應尚還靈敏，但容量小，易內泄并有壓力損失，不適于高壓和高頻動作的場合一般可用于小容量、低壓系統，用作蓄能和緩沖 充氣式蓄能器 （1）氣瓶式蓄能器（直接接觸式蓄能器） (2)活塞式蓄能器 (3)氣囊式蓄能器 氣瓶式蓄能器工作原理 氣壓油壓 釋放能量 氣瓶式蓄能器性能特點：容量大，但由于氣體混入油液中，影響系統工作的平穩性，而且耗氣量大，需經常補氣，僅適用于中、低壓大流量系統。
活塞式蓄能器工作原理 氣壓油壓 釋放能量 活塞式蓄能器性能特點：結構簡單，工作可靠，安裝容易，維修方便，壽命長，但因有摩擦，反應不靈敏，容量較小一般用于蓄能 氣囊式蓄能器工作原理 氣壓油壓 釋放能量 氣囊式蓄能器性能特點：重量輕、尺寸小、安裝容易、維護方便、慣性小、反應靈敏，但氣囊制造困難。
既可用于蓄能、又可用于緩和沖擊、吸收脈動 蓄能器容量計算 容量是選用蓄能器的依據，其計算視用途而異，現以氣囊式為例加以說明 作蓄能使用時蓄能器容量的計算 ∵ 蓄能器存儲和釋放的壓力油容量和氣囊中氣體體積的變化量相等，而氣體狀態變化應符合玻義耳氣體定律 ∴ 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 儲能器在吸收沖擊時的容量計算 吸收壓力脈動時蓄能器的容量計算 V0=Vi/0、6k 使用和安裝蓄能器 1 充氣式蓄能器中應使用惰性氣體（一般為氮氣） 2 蓄能器一般應垂直安裝，油口向下。
3 必須用支架或支板將蓄能器固定，且便于檢查、維修的位置，并遠離熱源 4 用作降低噪聲、吸收脈動和沖擊的蓄能 器應盡可能靠近振源 5 蓄能器與管路之間應安裝截止閥，供充氣或檢修時用，與液壓泵之間應安裝單向閥，防止油液倒流保護泵與系統。
6 搬運和拆裝時應排出壓縮氣體—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
