style="text-indent:25px">如果用戶選擇了錯誤的電磁閥型號，則會引起電磁閥工作的故障問題，例如超負荷的工作工況，就比較容易導致電磁閥零部件的損壞。如果電磁閥使用時間過長已經(jīng)損壞了，這種情況就要直接更換新的電磁閥?；蛘唠姶砰y的實際工作環(huán)境和所適合的范圍差距太大。導致電磁閥在工作的時候影響閥芯或者損壞電磁閥閥芯。例如使用的時候常閉型電磁閥常開使用，電源壓力、工作環(huán)境與電磁閥本身適應的分之一范圍不符合。例如工作環(huán)境的溫度、壓力等，或者介質(zhì)的屬性發(fā)生變化，而使用用戶仍然勉強使用，或者在不知道的情況下繼續(xù)使用，則同樣容易造成電磁閥閥芯故障問題。鋼球閥芯有很好的抗耐壓才能，但缺陷是起密封效果的橡膠密封圈易損耗，很快會老化。</p><div

style="text-indent:25px">閥芯材質(zhì)鑒別：化學和光譜分析。利用化學分析來對閥芯材質(zhì)中各種元素的含量進行確定是很早就已經(jīng)有的方法，而且這個方法根據(jù)長時間的使用可以說還是非常可靠的。而光譜分析指的是閥芯的材料會在高溫和高能量的激發(fā)下發(fā)射光譜，所以利用光譜分析也可以確定閥芯的材質(zhì)。火花鑒別。對金屬材料進行打磨的時候，往往會因為劇烈的摩擦而產(chǎn)生火花。而對閥芯材質(zhì)的鑒別正是依靠這個方法，對其進行打磨，靠辨別其火花的特點來鑒別其材質(zhì)的構(gòu)成。閥芯閥板的運動帶有擦拭性，故大多數(shù)的閥芯可用于帶懸浮固體顆粒的介質(zhì)。合肥閥芯公司修理</p><p
