油研柱塞泵是一种往复泵，归于体积泵，其柱塞靠泵轴的偏疼滚动驱动，往复运动，其吸入和排出阀都是单向阀。当柱塞外拉时，作业室内压力下降，出口阀封闭，低于进口压力时，进口阀翻开，液体进入；柱塞内推时，作业室压力升高，进口阀封闭，高于出口压力时，出口阀翻开，液体排出。R901137885PGF1-2X/2,8RE01VP1R901125550PGF2-2X/011RN20VM-A457R901125549PGF2-2X/006RN20VM-A457R901103807PGF3-3X/022RJ20VU2R901067539PGF2-2X/006RA01VP2-A381R901067272ABUKG-07-12/00K008/PGF2-19/90/S0160SO24R901055744ABHAG-0120SSO/PGF3-025+GF1/132M/014B975AR901054759ABPBG-PGF3-025E4/BG160/LR901050288PGF3-3X/032RN07VM-A447R901036894ABSKG-20AL9/PGF1-2,2/90L/L/1/S02J011AR901029605PGF2-2X/013LN01VM-A279R901021469PGF1-2X/1,7LA01VP1-A340BR901018829PGF2-2X/016RJ01VU2R900HA5596ABHAG-0100RS/PGF2-006/112M/002F433AR900984300PGF2-2X/019LJ20VU2R900984277PGF2-2X/013LL20VMK-A385R900984264PGF3-3X/025LN20VM-A262R900984249PGF3-3X/032RS07VMR900984240PGF2-2X/016LL01VMR900984214PGF2-2X/006RL01VMK-A385R900984213PGF3-3X/032LJ07VU2R900984209PGF3-3X/025RE07VE4-A384R900984206PGF2-2X/016RA01VP2PGH4-2X/032RE11VU2力士乐REXROTH齿轮泵)
