HGP-22A-F99RHGP-22A-F99RHGP-22A-F99RHGP-22A-F99R液压泵过度发热有两个原因，一是机械摩擦生热。由于运动表面处于干摩擦或半干摩擦状态，运动部件相互摩擦生热。二是液体摩擦生热。高压油通过各种缝隙泄漏到低压腔，大量的液压能损失转为热能。所以正确选择运动部件之间的间隙、油箱容积和冷却器，可以杜绝泵的过度发热和油温过高的现象。另外，回油过滤器堵塞造成回油背压过高，也会引起油温过高和泵体过热。。HGP-22A-F99R比例换向阀比例换向阀比例换向阀比例换向阀YB-D中压叶片泵比例换向阀HGP-22A-F99RAA4VSO180DFE1/30R-PZB25N00 AA11VLO145DRS/11L-NSD62K04 AHA4FO500/30R-PZH25K43 PA4VSG355HD1AT/30R-PPB10N000N A10VO71DFR1/31R-PPA12N00 AA6VM200HD1/63W-VSD527FB-SK A2FO12/61L-PZB06-S A11VO40DRS/10R-NZC12N00 AA7VO500HD2D/63R-VPH02 PA4CSG500HD1DU/30R-VPH35F014D-SO19 PA4VSG71EM1028/10R-PPB10KB49N-SO579 AA4VSO180LR2DY/30R-PPB13N00 AA10VE45HZ/52W1-VRF60N000 A4VG250EP4DT1/32R-NZD10F001SP-S A11VLO130LRDS/10R-NSD12K02 AHA4VSO250DP/30L-PPB13N00-SO890 PAA4CSG355EPD/30L-VRD85F994DE R902083206 AA10VG45EZ1DM1/10R-NSC60F003DH *AL* AA10VO45DR/31R-PSC62N00 AHA10VO45DRG/31L-PRC12K02 AA10VSO45DRG/31R-PPA12K26 A4VSO180LR2G/22R-PPB13N00 AA6VM160HA1/63L-VSD51XA-ES AA4VSO125HD1GBT/30R-PPB13G30 AA4VSO40DP/10R-EKD63N00E AA10VO100DR/31R-VPC12N00K A2FO23/61L-PPB06-S AA11VO60LR3DS/10R-NSC62K02 A2FM180/61W-VAB010 AA6VM250HA2/63W2-VZB020A AA10VO18ED72/53L-VSC12N00P AA10VSO140DR/31R-PSB12N00 AA10VSO100DR/31R-VPA12K07 A11VLO130EP2/10L-NZD12K82P。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 力士乐A4VG变量柱塞泵系列常用型号： 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。
