 很多时候,影响液压件工作效率的因素有很多,而其中抗磨液压油的质量高低占据了重要的比重。在诸多的检查过程中因为该部分出现问题而导致故障出现的情况不在少数,因此在日常的机械维护中液压油的质量高低是需要引起足够重视的。而对诸多的用户来说,液压油质量的好坏,不仅影响着工程机械的正常工作,而且会造成液压系统零部件的严重损坏。 现结合工作实践归纳出几种在无专用检测仪器情况下,简易鉴别液压油质量的方法。

抗磨液压油的质量好坏如何鉴别

一、液压油水分含量的鉴别

1.目测法

二、液压油杂质含量的鉴别

1、感观鉴别:

三、液压油粘度变化的鉴别

1、玻璃板倾斜法:取一块干净的玻璃板,将其水平放置,并将被测液压油滴一滴在玻璃上,同时 在旁边再滴一滴标准液压油(同牌号的新品液压油),然后将玻璃板倾斜,并注意观察:如果被测油液的 流速和流动距离均比标准油液大,则说明其粘度比标准油液低,反之,则说明其粘度比标准油液高。

2、玻璃瓶倒置法:将被测的液压油液与标准油液分别盛在两个大小和长度相同的透明玻璃瓶中 (不要装得太满),再用塞子将两瓶口堵上。将两瓶并排放置在一起,然后同时迅速将两瓶倒置。如果 被测液压油在瓶中的气泡比标准油液在瓶中的气泡上升得快,则说明油液的粘度比标准油液粘度低, 反之,则说明油液粘度比标准油液粘度高;若两种油液气泡上升的速度接近,则说明粘度也相似。

 

四、抗磨液压油质量变化的鉴别

1、油泵油液的鉴别:女人怎么靠自己赚钱从油泵中取出少许被测油液,若发现其已呈乳白色混浊状(有时像淡黄色的牛奶),且用燃烧法鉴别时,发现其含大量水分,用手感觉已失去粘性,则说明该油液已彻底乳化变质,不宜再用。

2、油箱油液的鉴别:从油箱中取出少许被测油液,用滤纸过滤,若滤纸上存留有黑色残渣,且有一 股刺鼻的异味,则说明该油液已氧化变质,也可直接从油箱底部取出部分沉淀油泥,若发现其中有许多 沥青和胶质沉淀,将其放在手指上捻捏,若感觉到胶质多,粘附性强,则说明该油已氧化变质摘要:介绍了一次液压油污染故障的排除过程,制定了预防这种故障再次发生的措施,在一次H3/36B建筑塔吊的降节过程中,进行第三个行程的操作时,突然出现液压缸顶升无力,活塞杆仅有非常微小的伸出动作。

哪么,如何判断市面上那个品牌的液压油质量好呢?如何选择真正的良品?
