采用补油泵供油的柱塞泵，使用3000h后，操作人员每日需对柱塞泵检查1～2次，检查液压泵运转声响是否正常。如发现液压缸或者液压马达速度下降或“憋车”(发动机负荷加重)时，就应该对补油泵解体检查，检查壳体内壁是否有刮伤现象，内齿轮泵间隙是否过大。对于自吸油型柱塞泵，液压油箱内的油液不得低于油标下限，要保持足够数量的液压油。液压油的清洁度越高，液压泵的使用寿命越长。代理博世力士乐轴向柱塞变量泵柱塞泵A10VSO/32系列精选常用型号：A10VS045DR/32R-VPB12N00A10VS045DRS/32R-VPB12NOOA10VSO45DFR1/32R-VPB12N00A10VS071DR/32R-VPB12N00A10VSO71DRS/32R-VPB22U00A10VSO71DRS/32R-VPB22U99A10VS071DFR1/32R-PPA12N00A10VS071DFR1/32R-VPB22U99-S2183A10VSO100DR/32R-VPB12N00A10VSO100DR/32R-PPB12N00A10VSO140DRS/32R-VPB12N00A10VSO100DFR1/32R-VPB12N00A10VS0100DR/32R-VPB22U99A10VS0140DR/32R-VPB22U99A10VSO140DRG/32R-PPB12NOOA10VSO45DFR1/32R-PPB12N00A10VSO45DFR/32R-PPB12N00A10VSO45DR/32R-PPB12N00A10VSO45DFR1/32R-VPB12N00A10VSO45DRS/32R-VPB12N00A10VSO45DRG/32R-VPB12N00A10VSO45DRS/32R-VPB22U99)
