一、液压系统清洗的意义

从使用的角度看，液压系统正常工作的首要条件是系统内部必须清洁。在新的设备运行之前,或一台设备经过大修之后,液压系统遭到污染是不可避免的,在软管、管道和管接头的安装过程中都有可能将污染物带入系统。即使新的油液也会含有一些令人意想不到的污染物。必须采取措施尽快将污染物滤出,否则在设备投入运行后不久就有可能发生故障,而且早期发生的故障往往都很严重,有些元件例如泵、马达有可能会遭到致命性的损坏系统冲洗的目的就是消除或Zui大限度地减少设备的早期故障。冲洗的目标是提高油液的清洁度,使系统油液的清洁度保持在系统内关键液压元件的污染耐受度内，以保证液压系统的工作可靠性和元件的使用寿命

二、循环冲洗装置

循环冲洗装置一般采用独立的大流量高压冲洗装置或系统的工作泵站进行管道的循环冲洗作业。独立的大流量高压冲洗装置的输出流量一般1000升/分以上，应由3-4台高压泵和1台低压泵组成，按照冶金液压系统的参数高压泵(31.5MPa)流量配置以250升/分、160升/分、100升/分、63升/分和低压泵(2.5MPa)400-600升/分可以组成不同的冲洗压力\流量的需要。

循环冲洗装置的输出管道接口应既能使所有冲洗泵的输出流量同时冲洗一个冲洗回路，也能组成同时冲洗多个独立的冲洗回路。

采用系统本身的工作泵站进行管道的循环冲洗作业也越来越多地获得广泛地应用和认可，采用工作泵站对系统管道冲洗是高效快速达到冲洗质量的可靠方法并具有更多的优点，具体表现在节省了宝贵的时间工期，节省了大量的临时配管材料，可利用工作泵站本身的正式的电气保护和系统中循环冷却、内循环过滤功能使得管道的系统冲洗效果更好更快。

三、循环冲洗的步骤

循环冲洗一般分为液压泵站到控制阀架主管道的冲洗和控制阀架到油缸和油马达支管道的冲洗。按照管道冲洗精度要求又分为中间管道的粗冲洗和所有管道的精冲洗。

液压泵站到控架主管道的冲洗连接回路较为简单，只需要在主管道的尾端将连接起来。

控制阀架到油缸和油马达支管道的冲洗就相对复杂一些。有时就需要制作很多临时冲洗配管来组成一个个冲洗回路，这时要注意的是前面提到的串联和并联冲洗时应该考虑的一些因素。

液压系统冲洗，可以按如下步骤进行：

在未安装敏感元件(如伺服阀等)之前，将管道及对污染物不敏感元件先装配起来，并将管子端部密封严实。

用跨接线代替敏感元件，将液压回路连接起来，并充液加压，进行冲洗，达到规定的清洁度为止。
