液压泵是为液压传动供应加压液体的一种液压元件，是泵的一种。它的服从是把动力机(如电动机和内燃机等)的机器能转换成液体的压力能。图中为单柱塞泵的事情原理。凸轮由电动机股动旋转。当凸轮推进柱塞向上活动时，柱塞和缸体组成的密封体积减小，油液从密封体积中挤出，经单向阀排到需求确本地去。当凸轮旋转至曲线的降落部位时，绷簧迫使柱塞向下，组成肯定真空度，油箱中的油液在大气压力的结果下进入密封容积。凸轮使柱塞不停地起落，密封容积周期性地减小和增大，泵就不停吸油和排油。R900981575PGH2-1X/006LE07MU2R900981517PGH3-1X/016LE07MU2R900981514PGH3-1X/013LE07MU2R900972378PGH2-2X/005RR07VU2R900968999PGH2-2X/005RE07VU2R900961561PGH3-2X/016LR07VU2R900961559PGH3-2X/011LR07VU2R900961558PGH3-2X/016RR07VU2R900961557PGH3-2X/013RR07VU2R900961556PGH3-2X/011RR07VU2R900961555PGH3-2X/016LE07VU2R900961554PGH3-2X/013LE07VU2R900961553PGH3-2X/011LE07VU2R900961552PGH2-2X/008LR07VU2R900961551PGH2-2X/008RR07VU2R900961550PGH2-2X/006LR07VU2R900961549PGH2-2X/006RR07VU2R900961548PGH2-2X/008LE07VU2R900951305PGH3-2X/016RE07VU2R900951304PGH3-2X/013RE07VU2R900951303PGH3-2X/011RE07VU2PGH3-1X/016LE07MU2力士乐齿轮泵优价)
