液压阀使用寿命超过90%的同行,美国客户通过对比选择AAK下单

AAK所生产的高压节流液压阀,使用寿命超过90%的同行,关键在于我们有自己专有的淬火及回火热处理工艺,通过淬火与不同温度的回火配合,可以大幅度提高液压阀的强度、韧性,以及疲劳强度,避免液压阀在长期的使用过程中出现变形、磨损等。目前约有不到10%的同行能与AAK液压阀PK使用寿命。

为了节省成本,有70%的厂家液压零件材料不做任何热处理,也有工厂做了热处理,但是都是外发加工,还有20%的工厂外加工是打一枪换一个地方,质量无法保证,稳定更是谈不上。由于存在这些行业通病,导致液压阀在使用过一段时间后,凸显许多问题,产品变形、磨损等等,一旦液压阀变形则会使卡阀更加严重,同时磨损会导致内泄漏加大,大大缩短液压阀的使用寿命。

上个月,美国客户在中国的采购负责人Jone找到我,他在聊天的过程中抱怨到,从2019年开始,不知道是什么原因,他的客户陆续出现投诉,而且问题都是出奇的一致,液压阀使用还不到三个月就出现变形,同时磨损的也很快。

我直接告诉他,是材料的热处理出了问题。70%的厂家液压零件材料不做任何热处理;即使做了热处理,20%的工厂的每次外加工是打一枪就换个地方,质量无法保证,更无法保证稳定。我寄了几个样品给他,并告诉他我们的材料硬度一定比他在采购的高,可以达到40-45HRC左右或者更高,主要是根据客户的使用场景而定,来确保液压阀的使用寿命。Jone貌似明白了其中问题的严重性,直接报告老板中国目前的行业现状。就在这个月,我们拿到他们的试单。

为了做好热处理,AAK控股了一家十年之久的热处理工厂。由于液压阀材料的淬火及回火热处理,对温度比较敏感,温度太低,硬度不够易变形,反之则导致破裂,唯有我们专有的热处理工艺,在有经验的师傅操作下,才能准确把握合适的温度。AAK还可以根据液压阀的不同使用工况条件,选择对应的热处理工艺,确定好温度区间,来保证液压阀的使用寿命。

使用寿命超过90%的同行,AAK液压阀等你来试单。
