?柱塞泵是在活塞泵的基礎(chǔ)上，在柱塞軸上加一個(gè)可自動(dòng)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(shí)現(xiàn)不同壓力和流量下對(duì)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(gè)配流油室根據(jù)流量的大小，它可以改變進(jìn)油速度。
柱塞泵也是通過柱塞與泵腔（葉輪）相接觸來實(shí)現(xiàn)配流的柱塞泵的進(jìn)油速度一般比較慢，進(jìn)流量也小當(dāng)流量超過柱塞的最大壓縮比(N)時(shí)，泵腔與壓氣機(jī)相通；當(dāng)油壓為最低壓縮比(M)時(shí)，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(dòng)的。
柱塞，是泵的動(dòng)力來源柱塞與泵體在配流閥上有兩個(gè)接觸點(diǎn)——進(jìn)油點(diǎn)和排氣點(diǎn)進(jìn)油點(diǎn)：進(jìn)油時(shí)壓出油室；排氣點(diǎn)：排出壓氣機(jī)出口進(jìn)油點(diǎn)（點(diǎn)）在進(jìn)油孔，排氣點(diǎn)在排氣口柱塞孔和進(jìn)油點(diǎn)接觸點(diǎn)當(dāng)柱塞與泵體接觸時(shí)，進(jìn)氣管出口端密封；當(dāng)柱塞壓下排氣口時(shí)，進(jìn)氣管出口端密封；當(dāng)柱塞排出壓氣機(jī)出口端密封時(shí)，壓氣機(jī)出口端密封與進(jìn)油口接觸點(diǎn)密封；當(dāng)柱塞不工作時(shí)，進(jìn)氣管出口端密封與排氣口接觸點(diǎn)密封；當(dāng)柱塞失效時(shí)，進(jìn)氣管出口方密封；如果液位高度在工作溫度下變化過大時(shí)請(qǐng)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(dòng)或損壞；活塞與殼體之間有密封面時(shí)應(yīng)注意緊固螺栓；當(dāng)液位高度大于工作溫度時(shí)也應(yīng)考慮使用柱塞（不是活塞）或油管來保證流體流向。
當(dāng)進(jìn)油點(diǎn)在工作溫度下變化過大時(shí)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(jìn)行更換氣門座是柱塞與泵腔和壓氣機(jī)之間傳遞熱能的媒介當(dāng)工作溫度超過其本身允許程度時(shí)會(huì)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。
