?輔助裝置功能:創(chuàng)造必要條件,確保液壓系統(tǒng)可靠、穩(wěn)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(guān)、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(nèi)大量供油(協(xié)助泵供油、作應(yīng)急動力源) 二、吸收液壓沖擊和壓力脈動 三、維持系統(tǒng)壓力(保壓補(bǔ)漏) 蓄能器的類型及特點(diǎn) 按結(jié)構(gòu)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(diǎn):結(jié)構(gòu)簡單,容量大,壓力穩(wěn)定,但結(jié)構(gòu)尺寸大而笨重,運(yùn)動慣性大,反應(yīng)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(diǎn):結(jié)構(gòu)簡單,反應(yīng)尚還靈敏,但容量小,易內(nèi)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(tǒng),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(diǎn):容量大,但由于氣體混入油液中,影響系統(tǒng)工作的平穩(wěn)性,而且耗氣量大,需經(jīng)常補(bǔ)氣,僅適用于中、低壓大流量系統(tǒng)。

蓄能器的類型、特點(diǎn)與工作原理(圖1)

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(diǎn):結(jié)構(gòu)簡單,工作可靠,安裝容易,維修方便,壽命長,但因有摩擦,反應(yīng)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(diǎn):重量輕、尺寸小、安裝容易、維護(hù)方便、慣性小、反應(yīng)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(jù),其計算視用途而異,現(xiàn)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(tài)變化應(yīng)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(yīng)使用惰性氣體(一般為氮?dú)猓? 2  蓄能器一般應(yīng)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(yuǎn)離熱源 4  用作降低噪聲、吸收脈動和沖擊的蓄能 器應(yīng)盡可能靠近振源 5 蓄能器與管路之間應(yīng)安裝截止閥,供充氣或檢修時用,與液壓泵之間應(yīng)安裝單向閥,防止油液倒流保護(hù)泵與系統(tǒng)。
