?1、軸瓦磨損嚴重，在使用一段時間后就會出現(xiàn)金屬磨損的現(xiàn)象，所以必須要及時的檢測軸瓦的磨損情況，否則有可能會造成軸頸與泵軸的連接不牢固！ 2、軸與軸承間隙過大：軸承磨損過大，會造成軸承內(nèi)壁上出現(xiàn)裂縫和磨損，這樣有可能產(chǎn)生漏油的現(xiàn)象，如果沒有及時的更換軸承，就會導(dǎo)致泵軸與軸承發(fā)生轉(zhuǎn)動不良，造成柱塞的轉(zhuǎn)速變化引起異響！解決方法：更換軸瓦。
如果軸和軸承的配合間隙過大，在工作中就會發(fā)出“嗒嗒”聲和類似于摩擦聲 檢查軸頸磨損情況，發(fā)現(xiàn)磨損情況為40~60μm,而且軸頸與軸承間隙為2~3mm,磨損情況比較嚴重檢查軸承磨損情況：軸頸的磨損情況為20~30μm,磨損到一定程度，就會將軸承的間隙擠壓到20~30μm,造成軸承過度發(fā)熱、摩擦系數(shù)下降、軸頸與滾珠軸承間產(chǎn)生微小間隙的情況。
軸頸及軸承應(yīng)更換新的軸承檢查軸頸的工作狀況，由于軸與軸承間隙過大，所以軸承必須裝在離心力保護裝置內(nèi)轉(zhuǎn)動軸頸使其軸向間隙減小；但當兩軸相對轉(zhuǎn)動時，在兩者表面發(fā)生相對摩擦產(chǎn)生異響，因此需要更換軸承并重新裝配；然后拆下軸承座檢查滾珠軸承間的配合間隙是否過大了。
3、對軸承座進行調(diào)整后，發(fā)現(xiàn)異響消失 故障原因：經(jīng)過檢測發(fā)現(xiàn)柱塞泵軸承座與柱塞泵軸之間，存在一道徑向間隙這道間隙主要是為了防止軸瓦滑動，減少軸在齒輪之間摩擦造成的磨損，但是在齒輪間隙較大時，齒輪會在主軸上移動造成的摩擦。
而且軸瓦本身也會磨損，所以當齒輪間隙太大的時候，會產(chǎn)生異常的摩擦聲 90R130-KP-5-CD-80-L-3-C8-H-05-GBA-38-35-24 90R130KP5CD80L3C8H05GBA383524 90-R-130-KP-5-CD-80-L-3-C8-H-05-GBA-38-35-24 90R130KP5CD80L3C8H05GBA383524 90R130-KP-5-CD-80-L-3-C8-H-09-GBA-38-35-24 90R130KP5CD80L3C8H09GBA383524 90-R-130-KP-5-CD-80-L-3-C8-H-09-GBA-38-35-24 90R130KP5CD80L3C8H09GBA383524 90R130-KP-5-CD-80-L-4-C8-H-03-GBA-23-23-24 90R130KP5CD80L4C8H03GBA232324 90-R-130-KP-5-CD-80-L-4-C8-H-03-GBA-23-23-24 90R130KP5CD80L4C8H03GBA232324 90R130-KP-5-CD-80-L-4-C8-H-03-GBA-42-42-24 90R130KP5CD80L4C8H03GBA424224 90-R-130-KP-5-CD-80-L-4-C8-H-03-GBA-42-42-24 90R130KP5CD80L4C8H03GBA424224 90R130-KP-5-CD-80-L-4-C8-H-06-GBA-40-40-30 90R130KP5CD80L4C8H06GBA404030 90-R-130-KP-5-CD-80-L-4-C8-H-06-GBA-40-40-30 90R130KP5CD80L4C8H06GBA404030 90R130-KP-5-CD-80-L-4-F1-F-06-GBA-35-35-24 90R130KP5CD80L4F1F06GBA353524 90-R-130-KP-5-CD-80-L-4-F1-F-06-GBA-35-35-24 90R130KP5CD80L4F1F06GBA353524 90R130-KP-5-CD-80-P-3-C8-H-02-GBA-38-38-24 90R130KP5CD80P3C8H02GBA383824 90-R-130-KP-5-CD-80-P-3-C8-H-02-GBA-38-38-24 90R130KP5CD80P3C8H02GBA383824 90R130-KP-5-CD-80-P-3-F1-F-02-GBA-42-42-24 90R130KP5CD80P3F1F02GBA424224 90-R-130-KP-5-CD-80-P-3-F1-F-02-GBA-42-42-24 90R130KP5CD80P3F1F02GBA424224 90R130-KP-5-CD-80-P-3-F1-F-03-GBA-36-36-24 90R130KP5CD80P3F1F03GBA363624 90-R-130-KP-5-CD-80-P-3-F1-F-03-GBA-36-36-24 90R130KP5CD80P3F1F03GBA363624 90R130-KP-5-CD-80-P-3-F1-H-00-GBA-36-36-24 90R130KP5CD80P3F1H00GBA363624 90-R-130-KP-5-CD-80-P-3-F1-H-00-GBA-36-36-24 90R130KP5CD80P3F1H00GBA363624 90R130-KP-5-CD-80-P-3-F1-H-03-GBA-32-32-28 90R130KP5CD80P3F1H03GBA323228 90-R-130-KP-5-CD-80-P-3-F1-H-03-GBA-32-32-28 90R130KP5CD80P3F1H03GBA323228 90R130-KP-5-CD-80-P-3-F1-H-03-GBA-35-35-24 90R130KP5CD80P3F1H03GBA353524 90-R-130-KP-5-CD-80-P-3-F1-H-03-GBA-35-35-24 90R130KP5CD80P3F1H03GBA353524 90R130-KP-5-CD-80-P-3-F1-H-03-GBA-35-35-28 90R130KP5CD80P3F1H03GBA353528 90-R-130-KP-5-CD-80-P-3-F1-H-03-GBA-35-35-28 90R130KP5CD80P3F1H03GBA353528 90R130-KP-5-CD-80-P-3-F1-H-03-GBA-36-36-24 90R130KP5CD80P3F1H03GBA363624 90-R-130-KP-5-CD-80-P-3-F1-H-03-GBA-36-36-24 90R130KP5CD80P3F1H03GBA363624。
