液壓泵站中壓力無法卸載的原因
液壓泵站系統中壓力(li)無(wu)法卸載的原因比(bi)較多(duo)，我們得具體情況(kuang)具體分析。一般來說(shuo)，液(ye)(ye)(ye)壓泵(beng)站(zhan)(zhan)系(xi)統壓力無法卸荷，多(duo)是控(kong)制(zhi)(zhi)(zhi)油(you)路(lu)(lu)出了問(wen)題(ti)。比(bi)如說(shuo)液(ye)(ye)(ye)控(kong)試壓泵(beng)，液(ye)(ye)(ye)壓泵(beng)站(zhan)(zhan)控(kong)制(zhi)(zhi)(zhi)油(you)路(lu)(lu)壓力低打不(bu)(bu)開單(dan)向閥(fa)；插裝閥(fa)打不(bu)(bu)開也多(duo)是控(kong)制(zhi)(zhi)(zhi)油(you)路(lu)(lu)有問(wen)題(ti)；當然也有閥(fa)芯卡死(si)或閥(fa)中的阻泥(ni)孔(kong)堵死(si)等原(yuan)因。那么控(kong)制(zhi)(zhi)(zhi)油(you)路(lu)(lu)會(hui)出什么問(wen)題(ti)呢？電(dian)磁閥(fa)因控(kong)制(zhi)(zhi)(zhi)電(dian)路(lu)(lu)問(wen)題(ti)不(bu)(bu)換向；控(kong)制(zhi)(zhi)(zhi)油(you)泵(beng)磨(mo)損(sun)嚴重，內漏(lou)而造成液(ye)壓泵站中(zhong)控(kong)制油(you)(you)路壓力過(guo)低；控(kong)制油(you)(you)路漏(lou)油(you)(you)造成控(kong)制油(you)(you)壓過(guo)低等。
