  處理方法：根據(jù)油泵的溫升情況，選用合適粘度的液壓油。找出油溫過高或過低的原因，并及時排除。高性能葉片油泵QX23-006/R高性能葉片油泵   高性能葉片油泵QX23-006/R第二、油缸在每次使用時，要進行全伸全縮的試運轉(zhuǎn)5個行程然后再帶載運行。為什么這樣做呢?這樣做可以排盡系統(tǒng)中的空氣，預熱各系統(tǒng)，能夠有效地避免系統(tǒng)中存在空氣或水，在油缸缸體造成氣體(或焦燒)現(xiàn)象，這樣會損害密封件，造成油缸內(nèi)泄等故障。雙聯(lián)高壓葉片泵PV2R11-31/12 PV2R11-4/10 PV2R11-8/14 PV2R11-31/23 PV2R11-25/17 PV2R11-28/14 PV2R11-17/31   PA4VSG250HD2D/30R-PPB10K680N-S1543 PA4VSG71HS4KP/10R-PPB10K680N A2FO32/61L-VAB05-S AA4VSO750HS4/30R-PZH25N00 R902075892 AA4VG90EP1DT1/32R-NUF52F071DH-S *AL* AA4VSO500DP/30R-PZH25K43 AA10VSO18DFR1/31L-PSC12N00 AA4FM71/10W-PZB01 AA10VSO28DFLR/31R-PPA12K01 力士樂A4VG變量柱塞泵系列常用型號： AA4VSO40LR2G/10R-PZB25N00-S1475 AA10VSO45DR/32R-VSD72UE2EE AAA10VSO28DFR/31R-VKC62N00 A7VO28DRG/63R-VPB01 R902084797 AA4VG71EP1D1/32R-NTFXXK021EC-S *AL* PA4VSG250HD1P/30R-PPB10N009N AA10VO60DFR/52R-PSC12N00 A11VO190DR/10R-NPD12N00 A11VO75LRDH2/10R-NZD12K81 AA4VSO125LR2GN/30R-PZB13N00 A10VG63HD3D1/10R-NSC10F043D AA6VM250EZ2/63W1-VZB010B PA4CSG500EPD/30R-VPH35F994N。R902080658 A6VE107EP1/63W-VZU020DHA-SK *SV* A11VO75DRS/10R-NSD12K02 A2FO125/61R-VBB05 AA11VO60DRS/10R-NSC62N00 R902092135 AA6VM107EZ3/63W-VSD520B-E AA10VSO10DFR/52R-PKC64N00E A11VLO260DRS/11R-NPD12N00 A6VE80DA1/63W-VAL02700B AAA10VSO140DR/31R-PKD62K08 AA10VO71DFR1/31L-PSC92K01 A4VG125HD3D1/32R-NZF02F001D-S AA10VO28DFR/52R-PSC62K68 AA4VSO125LR2G/30R-PZB25U99-S1475 AA10VSO18DR/31L-PPA12N00-SO169 AA10VO100DFR1/31R-VSC62K04 A4VG71EP4D1/32R-NAF02F011PP AA10VO28DFR/52L-PSC62N00 AA10FM28/52W-VRC64N000 AEA10VSO18DFR/31R-PPA12O20 A2FO5/60L-VBB07 AA10VO45DFR/31R-PSC12K01E AA4VSO71HS4P/10R-PPB13K01 AA6VM500EP2D/63W2-VZH017B。A2F40R2P3L2F55R2P3L2F55R2P3一、空負荷不能提升松開油泵與油缸連接管路接頭，觀察油泵工作情況。如果泵油，說明區(qū)段工作正常；反之，表明區(qū)段有故障。高性能葉片油泵QX23-006/R
