威格士柱塞泵工作原理威格士柱塞泵是往复泵的一种，属于体积泵，其柱塞靠泵轴的偏心转动驱动，往复运动，其吸入和排出阀都是单向阀。当柱塞外拉时，工作室内压力降低，出口阀关闭，低于进口压力时，进口阀打开，液体进入;柱塞内推时，工作室压力升高，进口阀关闭，高于出口压力时，出口阀打开，液体排出。带滑靴结构的轴向柱塞泵是目前使用***广泛的轴向柱塞泵，安放在缸体中的柱塞通过滑靴与斜盘相接触，当传动轴带动缸体旋转时，斜盘将柱塞从缸体中拉出或推回，完成吸排油过程。柱塞与缸孔组成的工作容腔中的油液通过配油盘分别与泵的吸、排油腔相通。变量机构用来改变斜盘的倾角，通过调节斜盘的倾角可改变泵的排量。概述威格士柱塞泵柱塞往复运动总行程L是不变的，由凸轮的升程决定。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。供油开始时刻不随供油行程的变化而变化。转动柱塞可改变供油终了时刻，从而改变供油量。柱塞泵工作时，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。进油过程当凸轮的凸起部分转过去后，在弹簧力的作用下，柱塞向下运动，柱塞上部空间(称为泵油室)产生真空度，当柱塞上端面把柱塞套上的进油孔打开后，充满在油泵上体油道内的柴油经油孔进入泵油室，柱塞运动到下止点，进油结束。供油过程当凸轮轴转到凸轮的凸起部分顶起滚轮体时，柱塞弹簧被压缩，柱塞向上运动，燃油受压，一部分燃油经油孔流回喷油泵上体油腔。当柱塞顶面遮住套筒上进油孔的上缘时，由于柱塞和套筒的配合间隙很小(0.0015-0.0025mm)使柱塞顶部的泵油室成为一个密封油腔，柱塞继续上升，泵油室内的油压迅速升高，泵油压力>出油阀弹簧力+高压油管剩余压力时，推开出油阀，高压柴油经出油阀进入高压油管，通过喷油器喷入燃烧室。回油过程柱塞向上供油，当上行到柱塞上的斜槽(停供边)与套筒上的回油孔相通时，泵油室低压油路便与柱塞头部的中孔和径向孔及斜槽沟通，油压骤然下降，出油阀在弹簧力的作用下迅速关闭，停止供油。此后柱塞还要上行，当凸轮的凸起部分转过去后，在弹簧的作用下，柱塞又下行。此时便开始了下一个循环。柱塞泵以一个柱塞为原理介绍，一个柱塞泵上有两个单向阀，并且方向相反，柱塞向一个方向运动时缸内出现负压，这时一个单向阀打开液体被吸入缸内，柱塞向另一个方向运动时，将液体压缩后另一个单向阀被打开，被吸入缸内的液体被排出。这种工作方式连续运动后就形成了连续供油。PVE19-B2L-STE9F-41-C16VPC24P-13PVE19-B2L-STE9F-41-C21VPD41B-13-255PVE19-B2L-STS2F-41-C17-12PVE19-B2L-STS2F-41-C21VP14P-13-365PVE19-B2L-STS5F-41-C16-12-302PVE19-B2L-STS9F-41-C21VP11B-13PVE19-B2R-A9-STS1F-41-C21-12PVE19-B2R-B26-STS1F-41-C21VPC30P-13-338PVE19-B2R-B26-STS33F-41-C12VP11B-13PVE19-B2R-B26-STS9F-41-C21-12PVE19-B2R-SFE13F-41-C14VP11P-13-253PVE19-B2R-STE9F-41-C21VP11P-D-13PVE19-B2R-STS16F-41-C14-12-061PVE19-B2R-STS1F-41-C21-12PVE19-B2R-STS28F-41-C12VP11B-13-237PVE19-B2R-STS28N-41-C21VP11B-13-121PVE19-B2R-STS9F-41-C16-12-223PVE19-B2R-STS9F-41-C17VPC14P-13-356PVE19-B2R-STS9F-41-C21-12PVE19-B2R-STS9F-41-C21VPC26B-13-387PVE19G-B2R-STS2N-41-C16VPC19B-13-305PVE21-B2L-MFS2F-41-C21VP15P-13-393PVE21-B2L-SFE9F-41-UV-20-293PVE21-B2L-STS13F-41-C20VPC17P-13-269PVE21-B2L-STS31F-41-C19VP14P-13-248PVE21-B2L-STS9F-41-C20VPC24B-13-390PVE21-B2R-A9-MFS2F-41-C21VP24P-13-333PVE21-B2R-B26-STS2F-41-C19-12PVE21-B2R-MFE2AF-41-C16VPC21P-13-307PVE21-B2R-MFE2AF-41-C20VPC30P-13-400PVE21-B2R-SFE2F-41-C19VPC24B-13-213PVE21-B2R-STE2F-41-C21VPC24B-D-13-268PVE21-B2R-STE9F-41-C20VPC24P-13-295PVE21-B2R-STS9F-41-C19VP11B-13PVE19/21RH&LHPVE35-QR122C21V172PVE35-QIR-A13-?22-C20-21PVE47R-A13-22-CM7-21PVE47R-1-22-C14-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-Q1830-1-30-CVP-12PVE21B2LSTE9F41C19VP11B13PVE21B2LSTS2F41C1912PVE21B2LSTS2F41C19VP11B13PVE21B2RSTE2F41C19VP11P13PVE21B2RSTE9F41C19VP11P13PVE21B2RSTS1F41C19VP11B13PVE21B2RSTS2F41C1912PVE21B2RSTS2F41C19VP11P13PVE21B2RSTS9F41C1912PVE210L08AA10B1811000100100CD0APVE210L08AA10B1824000100100CDEAPVE210L08AA10B182400A1AG100CD0APVE21AL21AA10B1811000100100CDEPVE21AR02AA10A1800000100100CD0PVE21AR05AA10B191100A100100CD0APVE21AR08AA10B181100A100100CD0PVE21AR08AA10B211100A1AG100CD0PVE21B2LSTS9F41C19VP11B13PVE21L930C10PVM045ER06CS02AAB21110000A0APVM045ER05CS01AAA2800000AA0APVM045ER05CS0200C2320000CA0APVM045ER05CE05AAA07000000A0APVM045ER06CS02AAC2811000DA0APVM045ER08CS02AAC28110000A0APVM045ER05CE02AAA07000000A0APVM020ER05CS01AAB23110000A0APVM020ER02AS02AAC23240000A0APVM020ER07CS02AAC2320000AA0APVM020ER02AE01AAA23000000A0APVM018ER02AE01AAA28000000A0APVM018ER01AS05AAB28110000A0APVM018ER01AE01AAB28110000A0APVM018ER01AS02AAA28000000A0APVM018ER02AS01AAC28110000A0APVM018ER01AS02AAC23110000A0APVM018ER07CS01AAB23200000A0APVM018ER01AS01AAB23110000A0APVM018ER03AE01AAB28200000A0APVM018ER05CS02AAC28110000A0APVM018ER02AS05AAC28200000A0APVM018ER06CS01AAA2800000AA0APVM018ER02AE01AAB25200000A0APVM018ER03AE05AAA07000000A0APVM018ER01AE01AAA28000000A0APVM018ER02AS02AAA28000000A0APVQ40-B2R-SS4F-20-C21-12PVQ40-B2R-SS4F-20-C21V11B-13PVQ40-B2R-SS4F-20-C21V11B-13-S33PVQ40-B2R-SS4F-20-C21V11P-13-CDPVQ40-MBR-MSNF-20-CM7D-12PVQ40-MBR-SSNF-20-C21D-12PVQ40-MBR-SSNF-20-CM11-12-S3PVQ40-MBR-SSNF-20-CM7-12VICKERS威格士柱塞泵PVQ45系列：PVQ45-B2L-A9-FS2F-20-C19-12PVQ45-B2L-A9-SS2F-20-C11V11B-13PVQ45-B2L-SE1F-20-C19-12-CDPVQ45-B2L-SE1F-20-C19D-12PVQ45-B2L-SE1F-20-CD19-12PVQ45-B2L-SE1F-20-CM7-12PVQ45-B2L-SE3F-20-C19-12PVQ45-B2L-SE3F-20-C19V11B-13PVQ45-B2L-SS1F-
