简介

液压泵

为液压传动提供加压液体的一种液压元件,是泵的一种。它的功能是把动力机(如电动机和内燃机等)的机械能转换成液体的压力能。影响液压泵的使用寿命因素很多,除了泵自身设计、制造因素外和一些与泵使用相关元件(如联轴器、滤油器等)的选用、试车运行过程中的操作等也有关系。

液压泵的工作原理是运动带来泵腔容积的变化,从而压缩流体使流体具有压力能。

必须具备的条件就是泵腔有密封容积变化。

分类

常用液压泵的种类:

1、按流量是否可调节可分为:变量泵和定量泵。输出流量可以根据需要来调节的称为变量泵,流量不能调节的称为定量泵。

2、按液压系统中常用的泵结构分为:齿轮泵、叶片泵和柱塞泵3种。

齿轮泵:体积较小,结构较简单,对油的清洁度要求不严,价格较便宜;但泵轴受不平衡力,磨损严重,泄漏较大。

叶片泵:分为双作用叶片泵和单作用叶片泵。这种泵流量均匀、运转平稳、噪音小、作压力和容积效率比齿轮泵高、结构比齿轮泵复杂。

液压泵过度发热有两个原因:一是机械摩擦生热。柱塞泵由于运动表面处于干摩擦

或半干摩擦状态,运动部件相互摩擦生热。二是液体摩擦生热。高压油通过各种缝隙泄漏到低压腔,大量的液压能损失转为热能;长期负荷过大导致卸荷阀频繁开启,油缸或阀有内泄(阀内部磨损,缸密封不好);阀或管道有堵塞现象。所以正确选择运动部件之间的间隙、油箱容积和冷却器,可以杜绝泵的过度发热和油温过高的现象。另外,回油过滤器堵塞造成回油背压过高,也会引起油温过高和泵体过热。 

液压泵转速高,排油压力高,工作环境恶劣,油液污染、油液选用不合规定或油液过少,都可造成泵损、泄漏。泵内泄漏可使其功率损失加大,磨损严重。油液中侵入空气后易于压缩,可造成泵干磨。液压泵内长时间的泄漏、干磨或压缩厉害, 必然发热,引起油液升温,造成系统发热。 

变量液压泵的伺服变量机构损坏也会造成系统发热,工作元件无力,或是系统过载,导致发动机、电动机闷车甚至停止工作 

伺服变量机构损坏,假如不能变量了,必然导致系统高压溢流,长期从而导致发热!伺服变量机构损坏有两种表现:不变量,过早变量。不变量导致系统过载,因为此时变量泵相当于定量泵。此时功率和压力成正比;过早变量,相同的压力时,系统流量变小,显得工作元件无力,系统工作速度变慢。假如伺服阀不能换向了那么液压泵就只能始终在较大排量下工作,

自然会发热。定量泵 溢流阀。

挖掘机是工程机械主力机种,是建设工程的主要生产工具,因此对挖掘机提出了很高的要求。要求节能低排放、**率、良好的操纵性和降低对环境的负荷等,要实现这些要求必须对挖掘机进行控制,由于液压控制信息处理能力差,不能光靠液压控制主要要靠电子控制。液压动力由液压泵提供,要知道液压泵是挖掘机液压系统的能源装置,将电机的机械能转换为液压能,输出流量和压力,在液压系统中占有非常重要的地位。如果液压泵出现故障,将会影响到整个液压系统的正常工作。
