?柱塞泵是在活塞泵的基礎(chǔ)上，在柱塞軸上加一個可自動調(diào)整的泵，根據(jù)管路的流量和壓力來調(diào)節(jié)柱塞泵的流量，它可以實現(xiàn)不同壓力和流量下對泵流量的控制下面是柱塞泵的原理柱塞泵的泵頭，首先是一個配流油室根據(jù)流量的大小，它可以改變進油速度。
柱塞泵也是通過柱塞與泵腔（葉輪）相接觸來實現(xiàn)配流的柱塞泵的進油速度一般比較慢，進流量也小當流量超過柱塞的最大壓縮比(N)時，泵腔與壓氣機相通；當油壓為最低壓縮比(M)時，活塞與泵腔相碰，但泵流量不變 1、從配流閥處壓出的液體應(yīng)是流動的。
柱塞，是泵的動力來源柱塞與泵體在配流閥上有兩個接觸點——進油點和排氣點進油點：進油時壓出油室；排氣點：排出壓氣機出口進油點（點）在進油孔，排氣點在排氣口柱塞孔和進油點接觸點當柱塞與泵體接觸時，進氣管出口端密封；當柱塞壓下排氣口時，進氣管出口端密封；當柱塞排出壓氣機出口端密封時，壓氣機出口端密封與進油口接觸點密封；當柱塞不工作時，進氣管出口端密封與排氣口接觸點密封；當柱塞失效時，進氣管出口方密封；如果液位高度在工作溫度下變化過大時請檢查柱塞是否磨損與變形，并應(yīng)調(diào)整與更換柱塞與殼體接觸處應(yīng)調(diào)整螺栓是否松動或損壞；活塞與殼體之間有密封面時應(yīng)注意緊固螺栓；當液位高度大于工作溫度時也應(yīng)考慮使用柱塞（不是活塞）或油管來保證流體流向。
當進油點在工作溫度下變化過大時應(yīng)檢查殼體等部件是否損壞；若不需要換裝殼體等部件，則可以直接進行更換氣門座是柱塞與泵腔和壓氣機之間傳遞熱能的媒介當工作溫度超過其本身允許程度時會出現(xiàn)漏氣現(xiàn)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。
