頗爾液壓濾芯的變形、彎曲、凹陷吸扁與沖破等產(chǎn)生的原因:
1.濾芯在工作中被污染物嚴重阻塞而未得到及時清洗,流進與流出濾芯的壓差增大,使濾芯強度不夠而導(dǎo)致濾芯變形破壞。
2.濾油器選用不當,超過了其允許的zui高工作壓力。例如同為紙質(zhì)濾油器,型號為ZU-100*20Z的額定壓力為6.3MPa,而型號為ZU-H100*20Z的額定壓力可達32MPa。如果將前者用于壓力為20MPa的液壓系統(tǒng),濾芯必定被擊穿而破壞。
3.在裝有高壓蓄能器的液壓系統(tǒng),因某種故障蓄能器油液反灌沖壞濾油器。
排除方法:
1. 及時定期檢查清洗濾油器
2. 正確選用濾油器,強度、耐壓能力要與所用濾油器的種類和型號相符
3. 針對各種特殊原因采取相應(yīng)對策
