液压系统油箱结构设计注意事项

液压系统油箱的结构设计及其注意事项。供大家参考学习，赶紧看看吧！

1、液压系统的油箱应有足够的容量。油箱的总容量包括油液容量和空气容量。油液容量一般应在最高液面以上留出等于油液容量的10%~15%的空气容量，以便形成油液的自由表面，容纳热膨胀和泡沫，促进空气分离，容纳停机或检修时靠自重流回油箱的油液。

2、以常用的矩形开式油箱为例，油箱的结构设计注意事项如下。

（1）、油箱的三个边的尺寸比例通常可按具体使用情况在1：1：1～1：2：3之间分配，并使液面高度为油箱高度的80%。

（2）、油箱的箱顶结构取决于它上面安装的元件，顶板应具有足够的刚度和隔振措施，以免因振动影响液压系统工作；箱顶应能形成滴油盘以收集滴落的油液。箱顶上要设置通气器（空气过滤器）、注油口。

（3）、对于钢板焊接的油箱，用来构成油箱体的钢板应具有足够的厚度。当箱顶与箱壁之间为不可拆连接时，应在箱壁上至少设置一个清洗孔。清洗孔的数量和位置应便于用手清理油箱所有内表面，清洗孔的法兰盖板应配有可以重复使用的弹性密封件。为了便于油箱的搬运，应在油箱四角的箱壁上方焊接圆柱形和钩形吊耳（也称吊环）。液位计一般设在油箱外壁上，并靠近注油口，以便注油时观测液面。

（4）、应在油箱底部最低点设置放油塞，以便油箱清洗和油液更换，箱底应朝向清洗孔和放油塞倾斜（通常为1/25～1/20），以促使沉积物（油泥或水）聚集到油箱中的最低点。油箱底至少离开地面150mm，以便于放油和搬运。油箱应设有支脚，支脚可以单独制作后焊接在箱底边缘上，也可以通过适当增加两侧壁高度，以使其经弯曲加工后兼作油箱支脚。如有必要，支脚上应开设地脚螺钉用固定孔。支脚应该有足够大的面积，以便可以用垫片或楔铁来调平。

（5）、在油液容量超过100L的油箱中应设置内部隔板，隔板要把系统回油区与吸油区隔开，并尽可能使油液在油箱内沿着油箱壁环流。隔板缺口处要有足够大的过流面积，使环流流速为0. 3～0. 6m/s。隔板下部应开有缺口，以使吸油侧的沉淀物经此缺口至回油侧，并经放油口排出。为了有助于油液中的气泡浮出液面，可在油箱内谩置金属除气网，并倾斜10°～30°布置。

（6）、管路的配置。液压系统的管路要进入油箱并在油箱内部终结。液压泵的吸油管和系统的回油管要分别进入由隔板隔开的吸油区和回油区，管端应加工成朝向箱壁的45°斜口，以增加开口面积。为了防止空气吸入（吸油管）或混入（回油管），以免搅动或吸入箱底沉积物，管口上缘至少要低于最低液面75mm，管口下缘至少离开箱底最高点50mm。吸油管前必须安装粗过滤器，以清除较大颗粒杂质，保护液压泵。

泄油管应尽量单独接入油箱并在液面以上终结。如果泄油管通人液面以下，要采取措施防止出现虹吸现象。

油管常从箱顶或箱壁穿过而进入油箱，穿孔处要妥为密封。最好在接口处焊上高出箱顶20mm的凸台，以免维修时箱顶上的污物落人油箱。如果油管从箱壁穿过而进入油箱，除了妥为密封外，还要装设截止阀以便于油箱外元件的维修。

（7）、油箱中如要安装热交换器等控温、测温装置，则应考虑其安装位置。

（8）、油箱内壁应涂敷耐油防锈涂料或进行喷塑处理。
