柱塞泵过分发热有两个缘故原由，一是机器摩擦生热。由于活动外貌处于干摩擦或半干摩擦状态，活动部件相互摩擦生热。二是液体摩擦生热。高压油通过种种漏洞走漏到低压腔，大量的液压能丧失转为热能。以是准确选择活动部件之间的间隙、油箱容积和冷却器，可以杜绝泵的过分发热和油温过高的征象。别的，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。A10VSO71DRS/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-VPB22U99A10VSO45DRG/32R-VPB22U99A10VSO71DFR1/32R-VPB22U99)
