<h5>時間：2019-05-16 13:54 作者:秩名</h5> </div> <div class="show_c"> <span style="font-size:16px;"> 不同類型的過濾器在液壓系統中應用各有不同，主要影響因素有壓力、流量和油品清潔度，下面我們來細看一下不同過濾器的用途：<br /> 1、吸油過濾器。吸油過濾器用于保護系統液壓元件，使其免受污染顆粒的損壞。但是它同時也增大了泵的吸油阻力，故要選用流通能力大、過濾效率高、納垢容量大、較小的壓力損失。如網式和線隙式的過濾器。過濾精度和效率是一對矛盾，過濾器的精度一般選擇80-200μm，滿足需要就行。如果是柱塞泵甚至可以考慮不適用過濾器。<br /> 2、壓力油路過濾器。壓力油路過濾器的作用是保護泵以外其他的液壓件，由于安裝位置壓力較高，應首先考慮耐高壓。要是用于保護抗污染能力較差元件（如伺服閥），需要考慮過濾精度和通流能力，推薦選用帶殼體的高壓濾油器。<br /> 3、回油管路過濾器?；赜凸苈愤^濾器主要作用就是將系統油液回油箱之前，將系統中的污物過濾掉，保證油箱內的油液清潔。過濾精度一般在10-50μm。在該過濾方式中，過濾器有可能會被堵塞，進而堵塞系統液壓元件。建議選用帶旁通閥的回油過濾器。另外在高壓下突然接通回油時會產生沖擊，所以要選用大流量的過濾器。如果背壓過大，則應加背壓閥，保護過濾器。<br /> 4 、旁路過濾器。旁路過濾器是由過濾器和小泵組成的獨立于液壓系統之外的過濾裝置，不受系統的影響。對變量泵的主系統，使用此過濾方法可以彌補低流量下過濾能力的降低。旁路過濾器一般選擇其過濾流量為主系統泵流量（max）的20%左右，同時過濾器精度要高。<br /> 值得一提的是，有不少人認為過濾器在清洗、沖洗后是可以重復使用的。嚴格的來說，這是完全錯誤的觀點，無論是何種材質、無論材質結構如何，沖洗多少會改變濾材的過濾間隙。<br /> 根據實際需求合理配置和維護不同類型的過濾器，以達到最經濟可靠的效果，是實現安全生產、和諧生產的需要，也是實現社會可持續性發展的有效途徑。所有這些，都應在液壓系統的設計及選擇中充分考慮到。</span><br /> </div>
