压力
对于蓄能器的计算,下列压力数据起到不同的作用:
p0 =预设气压
在室温下且液压油室排干
p0T =预设气压
在工作温度下
p1 =较小工作超压
p2 =较大工作超压
t较大 =较大工作温度
为了尽可能实现蓄能器体积的利用和长久的使用寿命,建议遵守以下值:
p0,t较大=0.9 p1
液压压力不应超过填注压力的四倍,否则会对隔膜的弹性产生过大的应力,导致压缩变化太大而气体加热强烈。
工作模式
液压油几乎都是不能压缩的,因此不能存储压力能。液压/气动蓄能器使用气体的可压缩性来存储液压油。所有氮气的清洁度等级至少应为 4.0:
p1 与 p2 之间的差别越小,隔膜的使用寿命越长。但是,较大蓄能器容量的工作比也将相应减小。
隔膜式蓄能器 p2 4 p0
若想在蓄能器中获得更高的压力比 (p0 : p2 > 1 : 4),可以在蓄能器的气体侧安装填料。
这将减少有效气体体积 V1,但可保护隔膜不会出现不允许的变形。
液压蓄能器的作用和主要用途
1.存贮能量,应急液压
蓄能器被广泛利用作辅助能源,与压力继电器组合使用,在间歇工作的场合,可作为辅助能源,实现液压泵的小型化并可节省能源,如钢厂炼钢炉的倾转液压系统。
2.吸收脉动,平稳系统
液压泵排出的液体都具有较大的脉动,这种脉动会使液压系统产生噪声、振动,并破坏系统的工作稳定性;在液压泵出口处使用蓄能器可以有效的衰减脉动,使装置平稳的工作,这在某些准确设备中犹为重要。
3.吸收冲击,保护回路
在液压回路中,由于液压阀急速闭合而发生载荷剧变;这种剧变会产生很大的瞬间冲击压力会破坏管道、连接接头或其它液压元件,并产生剧烈的振动和噪声;使用蓄能器可有效缓和冲击,保护液压装置。如压铸机、高空混凝土输送机中液压系统中使用的蓄能器就很好的体现了这一功能。
4.热膨胀消减泄漏补偿
在压力控制的闭式回路中,使用蓄能器可有效的补偿温度降低、内部泄漏或外部泄漏而引起的压力降低;也可有效控制由于温度升高而引起的压力上升、从
而使系统稳定的工作。
5.吸收振动,减振平衡
蓄能器中胶囊充满气体可起到气体弹簧的作用,可吸收来自汽车、提升机、移动吊车等驱动和悬挂系统的机械振动,保持车辆的平稳性。
6.液体或液气分隔传送
使用蓄能器可实现两种不相容的液体或液体与气体之间的能量传递,进行隔绝输送。蓄能器是贮存高压油的装置,当泵处于正常的无负荷状态或空转状态,就可给蓄能器充油。
蓄能器贮存的高压油在需要时可以释放出来,补充泵的流量,或在停泵时给系统供油。我们现使用的蓄能器大多为隔膜式和气囊式;蓄能器靠压缩惰性气体来贮存能量,通常采用氮气,实际充气压力不能高于临界值,大多数场合,充气压力值应在系统高压力值的1/3到1/2的范围内,这样效果好,回路工作特性很少变化。特别强调的是,不要使用氧气或含氧气的混合气体。
0531600600液压蓄能器
气体式蓄能器以波义尔定律(PVn=K=常数)为基础,通过****完成能量转化,使用时首先向蓄能器充入预定压力的气体。当系统压力超过蓄能器内部压力时,油液****,将油液中的压力转化为气体内能;当系统压力低于蓄能器内部压力时,蓄能器中的油在高压气体的作用下流向外部系统,释放能量。选择适当的充气压力是这种蓄能器的关键。这类蓄能器按结构可分为管路消振器、气液直接接触式、活塞式、隔膜式、气囊式等。

蓄能器的功能主要分为存储能量、吸收液压冲击、消除脉动和回收能量四大类。
较好类:存储能量。这一类功用在实际使用中又可细分为:①作辅助动力源,减小装机容量;②补偿泄漏;③作热膨胀补偿;④作紧急动力源;⑤构成恒压油源。
第二类:吸收液压冲击。换向阀突然换向、执行元件运动的突然停止都会在液压系统中产生压力冲击,使系统压力在短时间内快速升高,造成仪表、元件和密封装置的损坏,并产生振动和噪声。为保证吸收效果,蓄能器应设置在冲击点附近,所以蓄能器一般装设在控制阀或液压缸等冲击源之前,可以很好地吸收和缓冲液压冲击。
第三类:消除脉动、降低噪声。对于采用柱塞泵且其柱塞数较少的液压系统,泵流量周期变化使系统产生振动。装设蓄能器,可以大量吸收脉动压力和流量中的能量,在流量脉动的一个周期内。瞬时流量高于平均流量的部分油液被蓄能器吸收,低于平均流量部分由蓄能器补充,这就吸收了脉动中的能量,降低了脉动,减小了对敏感仪器和设备的损坏程茺。
第四类:回收能量。用蓄能器回收能量是目前研究较多的一个领域。能量回收可以提高能量利用率,是节能的一个重要途径。蓄能器因为可以暂存能量,所以可以用来回收多种功能、位置势能。这方面的主要研究有:①回收车辆制动能量;②回收工程机械动臂机构位能;③回收液压挖掘机转台制动能量;④回收石油修井机及钻机管下落重力势能;⑤回收电梯下行重力势能。

蓄能器充气:
蓄能器补充氮气通常有两种方式:
1,当蓄能器使用压力低于8MPa时可通过氮气瓶和充氮工具来补充氮气,将充氮工具一端与氮气瓶相连,另一端与蓄能器相连,打开氮气瓶阀门即可完成充气。
2,当蓄能器使用压力高于8MPa时,通过氮气瓶和充氮工具已无法完成充气,在这种情况下可用充氮车,充氮工具,氮气瓶三者配合使用来给蓄能器补充氮气。首先用高压软管将氮气瓶和充氮车进气口连接起来,充氮车出气口通过充氮工具与蓄能器进气口连接起来,在充氮车上设定好输出压力,然后打开氮气瓶阀门,充氮车接上电源,打开充氮车开机旋钮即可完成充气。
