柱塞泵是在活塞泵的基础上，在柱塞轴上加一个可自动调整的泵，根据管路的流量和压力来调节柱塞泵的流量，它可以实现不同压力和流量下对泵流量的控制下面是柱塞泵的原理柱塞泵的泵头，首先是一个配流油室根据流量的大小，它可以改变进油速度。
柱塞泵也是通过柱塞与泵腔（叶轮）相接触来实现配流的柱塞泵的进油速度一般比较慢，进流量也小当流量超过柱塞的最大压缩比(N)时，泵腔与压气机相通；当油压为最低压缩比(M)时，活塞与泵腔相碰，但泵流量不变 1、从配流阀处压出的液体应是流动的。
柱塞，是泵的动力来源柱塞与泵体在配流阀上有两个接触点——进油点和排气点进油点：进油时压出油室；排气点：排出压气机出口进油点（点）在进油孔，排气点在排气口柱塞孔和进油点接触点当柱塞与泵体接触时，进气管出口端密封；当柱塞压下排气口时，进气管出口端密封；当柱塞排出压气机出口端密封时，压气机出口端密封与进油口接触点密封；当柱塞不工作时，进气管出口端密封与排气口接触点密封；当柱塞失效时，进气管出口方密封；如果液位高度在工作温度下变化过大时请检查柱塞是否磨损与变形，并应调整与更换柱塞与壳体接触处应调整螺栓是否松动或损坏；活塞与壳体之间有密封面时应注意紧固螺栓；当液位高度大于工作温度时也应考虑使用柱塞（不是活塞）或油管来保证流体流向。
当进油点在工作温度下变化过大时应检查壳体等部件是否损坏；若不需要换装壳体等部件，则可以直接进行更换气门座是柱塞与泵腔和压气机之间传递热能的媒介当工作温度超过其本身允许程度时会出现漏气现象 90-R-130-KA-5-CD-80-S-4-C8-F-03-GBA-38-38-24 90R130KA5CD80S4C8F03GBA383824 90-R-130-KA-5-CD-80-S-4-C8-H-00-GBA-36-36-24 90R130KA5CD80S4C8H00GBA363624 90R130-KA-5-CD-80-S-4-C8-H-00-GBA-38-38-24 90R130KA5CD80S4C8H00GBA383824 90-R-130-KA-5-CD-80-S-4-C8-H-00-GBA-38-38-24 90R130KA5CD80S4C8H00GBA383824 90R130-KA-5-CD-80-S-4-C8-H-03-GBA-35-35-28 90R130KA5CD80S4C8H03GBA353528 90-R-130-KA-5-CD-80-S-4-C8-H-03-GBA-35-35-28 90R130KA5CD80S4C8H03GBA353528 90R130-KA-5-CD-80-S-4-C8-H-03-GBA-36-36-24 90R130KA5CD80S4C8H03GBA363624 90-R-130-KA-5-CD-80-S-4-C8-H-03-GBA-36-36-24 90R130KA5CD80S4C8H03GBA363624 90R130-KA-5-CD-80-S-4-C8-H-03-GBA-38-38-24 90R130KA5CD80S4C8H03GBA383824 90-R-130-KA-5-CD-80-S-4-C8-H-03-GBA-38-38-24 90R130KA5CD80S4C8H03GBA383824 90R130-KA-5-CD-80-S-4-C8-H-05-GBA-42-42-24 90R130KA5CD80S4C8H05GBA424224 90-R-130-KA-5-CD-80-S-4-C8-H-05-GBA-42-42-24 90R130KA5CD80S4C8H05GBA424224 90R130-KA-5-CD-80-S-4-F1-F-03-GBA-42-42-24 90R130KA5CD80S4F1F03GBA424224 90-R-130-KA-5-CD-80-S-4-F1-F-03-GBA-42-42-24 90R130KA5CD80S4F1F03GBA424224 90-R-130-KA-5-CD-80-S-4-F1-H-02-GBA-38-38-28 90R130KA5CD80S4F1H02GBA383828 90R130-KA-5-CD-80-S-4-F1-H-04-GBA-42-42-24 90R130KA5CD80S4F1H04GBA424224 90-R-130-KA-5-CD-80-S-4-F1-H-04-GBA-42-42-24 90R130KA5CD80S4F1H04GBA424224 90R130-KA-5-DE-80-D-4-C8-L-03-GBA-42-42-24 90R130KA5DE80D4C8L03GBA424224 90-R-130-KA-5-DE-80-D-4-C8-L-03-GBA-42-42-24 90R130KA5DE80D4C8L03GBA424224 90R130-KA-5-DE-80-L-3-C8-F-03-GBA-45-45-24 90R130KA5DE80L3C8F03GBA454524 90-R-130-KA-5-DE-80-L-3-C8-F-03-GBA-45-45-24 90R130KA5DE80L3C8F03GBA454524 90R130-KA-5-DE-80-L-3-C8-H-03-GBA-29-29-24 90R130KA5DE80L3C8H03GBA292924 90-R-130-KA-5-DE-80-L-3-C8-H-03-GBA-29-29-24 90R130KA5DE80L3C8H03GBA292924 90R130-KA-5-DE-80-L-3-C8-H-03-GBA-35-35-24 90R130KA5DE80L3C8H03GBA353524 90-R-130-KA-5-DE-80-L-3-C8-H-03-GBA-35-35-24 90R130KA5DE80L3C8H03GBA353524 90-R-130-KA-5-DE-80-L-3-C8-H-03-GBA-38-38-24 90R130KA5DE80L3C8H03GBA383824 90R130-KA-5-DE-80-L-3-C8-H-03-GBA-42-42-24 90R130KA5DE80L3C8H03GBA424224 90-R-130-KA-5-DE-80-L-3-C8-H-03-GBA-42-42-24 90R130KA5DE80L3C8H03GBA424224 90R130-KA-5-DE-80-L-4-C8-F-05-GBA-35-35-24 90R130KA5DE80L4C8F05GBA353524 90-R-130-KA-5-NN-80-S-4-F1-H-03-GBA-30-30-24 90R130KA5NN80S4F1H03GBA303024。
