ATOS柱塞(sai)泵(beng)最(zui)重要(yao)(yao)的(de)(de)(de)部件是(shi)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)，如果軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)出現(xian)游(you)隙，則不能保證(zheng)液壓(ya)(ya)(ya)泵(beng)內部三對(dui)磨(mo)擦副的(de)(de)(de)正常間隙，同(tong)時(shi)也會破(po)壞各磨(mo)擦副的(de)(de)(de)靜液壓(ya)(ya)(ya)支承(cheng)(cheng)(cheng)(cheng)(cheng)油膜厚度，降低柱塞(sai)泵(beng)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)的(de)(de)(de)使用壽(shou)命(ming)。據液壓(ya)(ya)(ya)泵(beng)制(zhi)造(zao)廠提供的(de)(de)(de)資(zi)料(liao)，軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)的(de)(de)(de)平均使用壽(shou)命(ming)為10000h，超過此值就(jiu)需要(yao)(yao)更(geng)換(huan)新口。拆(chai)卸下(xia)來的(de)(de)(de)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)，沒有專業檢測儀器是(shi)無法檢測出軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)的(de)(de)(de)游(you)隙的(de)(de)(de)，只能采用目測，如發現(xian)滾柱表面有劃痕(hen)或(huo)變色，就(jiu)必須更(geng)換(huan)。

ATOS柱塞泵配流盤(pan)有平面(mian)(mian)配流和球面(mian)(mian)配流兩種(zhong)形(xing)式。球面(mian)(mian)配流的磨擦副，在缸體配流面(mian)(mian)劃(hua)痕比較淺(qian)時(shi)，通過(guo)研磨手段(duan)修復；缸體配流面(mian)(mian)溝槽(cao)較深時(shi)，應先采用(yong)“表面(mian)(mian)工(gong)程技(ji)術"手段(duan)填平溝槽(cao)后，再進行研磨，不(bu)可(ke)盲目研磨，，以防銅層變薄或漏油出(chu)鋼基。

ATOS柱塞泵主要特點:
采(cai)用雙柱塞(sai)結構，壓力(li)脈動小(xiao)，寶石球壽命長(chang)；
采用進口寶(bao)石柱塞和寶(bao)石球(qiu)，確保流量精確
通過 RS232 接(jie)口(kou)與電腦(nao)通訊，可直接(jie)由電腦(nao)進行(xing)控制 ；
接觸介質材(cai)料耐(nai)有機溶劑腐(fu)蝕(shi)；
大屏幕(mu)液(ye)晶顯示；
精心設(she)計(ji)的排氣(qi)裝(zhuang)置有效除去輸(shu)送液體中的氣(qi)泡。
流(liu)量與壓力(li)設定可(ke)記憶 可(ke)與PLC實(shi)現通訊（定制）
實(shi)時顯示(shi)當前(qian)壓(ya)(ya)力(li)(li)、設(she)(she)定(ding)(ding)壓(ya)(ya)力(li)(li)、設(she)(she)定(ding)(ding)流(liu)量 ； 實(shi)時曲線顯示(shi)泵工(gong)作壓(ya)(ya)力(li)(li) 可(ke)按(an)兩種方式設(she)(she)定(ding)(ding)流(liu)量和壓(ya)(ya)力(li)(li)，快捷實(shi)用 ； 具有定(ding)(ding)時功能(neng)，方便設(she)(she)定(ding)(ding)泵的工(gong)作時間 ； 可(ke)保存當前(qian)工(gong)作壓(ya)(ya)力(li)(li)，便于查看 ； 可(ke)打印當前(qian)壓(ya)(ya)力(li)(li)等(deng)重要參(can)數 。
