1 液压阀机械故障   液压阀出现的机械故障是因为液压阀的尺寸、精度、粗糙度等技术和指标要求,没有达到规定的要求,没有对液压系统配件中各项元件间的配合度进行有效的保证和比对,或者对元件没有保护好,造成元件损伤等,这些都是造成液压系统配A10VG45液压泵配件件中液压阀工作失效的因素。

2.1 液压卡紧   这种现象的产生主要是因为液压系统配件中阀孔与阀芯之间的孔隙非常小,其中的液压油向阀芯移动的过程中需要克服的只有摩擦力,但是在实际工作中液压油移动过程中需要克服的摩擦力非常的大,阀芯的移动非常的吃力,这个现象我们将其称为液压卡紧现象。   产生原因:液压卡紧现象的产生的原因有很多种,例如,有的是因为脏物进入到阀孔缝隙中,造成阀芯移动困难,有的是因为阀孔缝隙过小,在系统运行中液压油的温度升高,导致阀芯膨胀卡死,无法移动。导致液压卡死现象的主要原因是阀体等零件的几何形状存在误差、同心度发生变化等,造成的不平衡液压力,进而产生液压卡紧现象。   危害:液压系统配件产生液压卡死之后,会影响整个液压系统配件的稳定性,造成液压系统配件中元件的动作受到影响,将该系统原有的自动循环进行破坏,进而造成液压设备发生故障。如果液压系统配件产生的液压卡紧是电磁力驱动,这种卡紧将会造成整个电磁铁的烧坏,也会加速其他元件的磨损程度,将液压系统配件的元件寿命缩减。   对策:为了将液压系统配件运行中的液压卡紧现象消除或者减小,可以采用的方法有,第一,定期的更换液压油等液压系统配件使用油液,对油液中的脏物、杂物进行清除,保证油液的清洁度,阿托斯液压泵配件防止因为杂物的浸入,造成元件移动困难,发生卡紧或者是卡死现象。第二,保证液压阀等阀门的阀体和阀芯之间的配合度,对液压系统配件工作中的油温进行控制,避免油温过高造成阀芯膨胀发生卡紧现象。第三,在液压阀的阀芯某一部位开设一个均压槽,但是不能影响其正常工作,并且要保证均压槽的通畅[2]。
