REXROTH柱塞泵，是由电动机提供泵的动力，经鼓型齿联轴器带动减速机转动。由减速机减速带动曲轴旋转。通过曲柄连杆机构，将旋转运动转变为十字头和柱塞为往复运动。当柱塞向后死点移动时，泵容积腔逐步增大，泵腔内压力降低，当泵腔压力低于进口压力时，吸入阀在进口端压力作用下开启，液体被吸入；当柱塞向前死点移动时，泵腔内压力增大，此时吸入阀关闭，排出阀打开，液体被挤出液缸，达到了吸入和排出的目的。 工作时，在喷油泵凸轮轴上的凸轮与柱塞弹簧的作用下，迫使柱塞作上、下往复运动，从而完成泵油任务，泵油过程可分为以下三个阶段。 结论：通过上述讨论，得出下列结论 ① 柱塞往复运动总行程L是不变的，由凸轮的升程决定。 ② 柱塞每循环的供油量大小取决于供油行程，供油行程不受凸轮轴控制是可变的。 ③ 供油开始时刻不随供油行程的变化而变化。 ④ 转动柱塞可改变供油终了时刻，从而改变供油量。 德国力士乐柱塞泵型号： A10VSO18DFR1/31R-PPA12N00 A10VSO18DFR1/31R-PPB12N00 A10VSO18DFR1/32R-VPB12N00 A10VG18HD1/10L-NSC16N003E A10VSO18DFR1/31R-PPA12N00 A10V028DR/31R-PSC12N00 A10VS028DR/31R-PPA12N00 A10VSO28DR/32R-VPB121N00 A10VSO28DFR/31R-PSA12N00 A10VSO28DFR1/31R-PPA12N00 A10VSO28DFR1/32R-VPB12N00 A10VSO28DRF1/31R-PSA12N00 E-A10VSO28DFR1/31R-PPA12N00 A10VSO28DR/31R-PSC12N00 A10V028DR/31R-PSC62K01 A10V028DFR1/31R-PSC62N00 A10VSO45DFR1/31R-PPA12N00 A10VSO45DFR1/32R-VPB12N00 A10VSO45DR/31R-PPA12N00 A10VSO45DR/31R-PPA12K25 A10VSO45DFR1/31R-PPA12N00 A10VSO58DFR1/31R-PPA12N00 A10VS045DFR1/31RPPA12NOO E-A10VSO45DFR1/31R-PPA12N00 A10VS045DFR/31R-PPA12NOO-SO32 A10VS045DR/31R-PPA12N00 A10VS045DR/52R-PC12N00 A10V045DFR1/31R-PSC62K02 A10VSO45DFR1/31R-PPA12N00 A10VS045DR/31RPPB12-NDD A10VO45DFR1/31R-PSC62K02 A10VSO71DFR1/32R-VPB22U99 A10VSO71DFR1/31R-PPA12N00 A10VSO71DFR1/32R-VPB12N00 A10VSO71DFR1/31R-PPA12KB5 A10VSO71DFR/31R-PSC62K07 A10VO71DFRI/34 PSC6402-S0225 A10VSO71FR1/31R-PPA12N00 A10VSO71DFR1/31R-PPB12NOO E-A10VSO71DFR1/31R-PPA12N00 A10VO71DFR1/31RPSC62K07 A10VSO71DFR/31R-PPA12KB3 A10VS071DR/31R-PPA12N00 A10VS071DFR/31R-PPA12N00 A10VS071DFR1/31R-PPA12N00 A10VSO71DFR1/31R-PPA12N00 A10VSO71DFR1/32R-VPB22U99 EA10VSO71DR/31R-PPA12N00 A10VS0100DR/31R-PPA12N00 A10VS0100DR/32R-VPB22U99 A10VSO100DFR1/32R-VPB12N00 A10VSO100DFR1/31R-PPA12K A10VSO100DFR1/31R-PPA12KB3 EA10VSO100PFR1/31R-PPA12N00 A10VSO100DFR/31RPSB12K24 A10VSO100DR/31R-VPA12N00 A10VSO100DR/31R-PPA12N00 A10VS0100DFR1/31R-PPA12N00 A10VS0100DFR1/32R-VPB12N00 A10V0100DR/31R-PSC11N00 A10VS0100DR/31R-PTA12N00 A10VSO100DR/31R-PPA12N00 A10VSO100DFR1/32R-VPB12N00 A10VSO140DFR1/31R-PPB12N00 A10VSO140DFLR1/31R-PPB12KO1 A10VSO-140DR/31R-PPB12N00 A10VSO140DFR1S/31RPPB12N0 A10VSO140DFR1/31R-PPB12N00 A10VS0140DFLR/31R-PPB12N00 A10VSO140DR/31R-PPB12N00 A10VS0140DRS/32R-VPB12N00 E-A10VSO140D/31R-PPB12N00 A10VSO140DFR1/31R-PPB12N00 A10VS0140DR/32R-VPB12N00 AE-A10VSO140D/31R-PPB12N00 A10VSO140DR/31R-PPB12N00 A10VSO140DRS/32R-VPB12N00 A10VSO140DFR1/31R-PPB12N00 A10VSO140DFR1/32R-VPB12N00 A10VSO140DRS/32R-VPB12N00 |
