?當(dāng)柱塞泵與其他零部件接觸不良或液壓油品質(zhì)不好時(shí),不得使用(如: a、不允許將壓力油直接注人油箱;b、嚴(yán)禁在油底殼等處加裝安全閥;c、當(dāng)壓力表指針指示過高時(shí),應(yīng)檢查各元件有無損傷;d、壓力油是否變質(zhì)或油質(zhì)是否良好;e、因發(fā)動(dòng)機(jī)長期不用應(yīng)及時(shí)更換;f、因柱塞、轉(zhuǎn)子彎曲所致,在使用中必須經(jīng)常檢查,必要時(shí)進(jìn)行修磨;f、當(dāng)工作氣壓高于1.0MPa或油液混合物溫度超過100℃或壓力大于0.8MPa時(shí),應(yīng)及時(shí)停車檢驗(yàn)或維修。

液壓系統(tǒng)壓力不穩(wěn)定應(yīng)立即停機(jī)分析原因(圖1)

否則造成發(fā)動(dòng)機(jī)損壞則應(yīng)立即停止使用!否則將損壞泵體、液壓油系統(tǒng) 1、壓力大于0.7MPa時(shí),需將柱塞全部換掉; a、注意各壓力表指針指示是否正常;b、經(jīng)常檢查各部位螺栓是否松動(dòng),并調(diào)整各部位間隙;c、將壓力表指針調(diào)至規(guī)定壓力狀態(tài);d、當(dāng)各壓力表指針指示值低于0.5MPa時(shí),則需檢查各總成是否有損傷;e、如果發(fā)現(xiàn)液壓系統(tǒng)壓力不穩(wěn)定而應(yīng)立即停機(jī)分析原因;f、對(duì)于已經(jīng)出現(xiàn)裂紋的零件,在擰緊螺母前,需要先用砂紙打磨裂紋上毛刺。

2、超過0.7MPa時(shí),需將柱塞全部換掉 因?yàn)橹怯袑?dǎo)向作用的當(dāng)柱塞工作在高負(fù)荷下時(shí),會(huì)出現(xiàn)打滑現(xiàn)象;同時(shí),還會(huì)造成轉(zhuǎn)子彎曲、擺動(dòng)等不良現(xiàn)象,從而引起缸套和閥套的磨損這就是為什么要選用高品質(zhì)柱塞泵生產(chǎn)廠家提供。

所以,使用前一定要仔細(xì)檢查泵所用配件是否完好,同時(shí)查看機(jī)油是否正常和液壓系統(tǒng)油是否干凈如果發(fā)現(xiàn)油質(zhì)不好、系統(tǒng)有積炭等問題,要及時(shí)更換新油;若發(fā)現(xiàn)磨損嚴(yán)重時(shí),則應(yīng)該立即停機(jī),及時(shí)修理;否則將損壞泵體內(nèi)油液。

對(duì)液壓系統(tǒng)進(jìn)行清洗疏通;使柱塞能夠繼續(xù)正常使用 90R250-HF-5-BC-80-T-3-F1-J-03-NNN-23-23-24 90R250HF5BC80T3F1J03NNN232324 90-R-250-HF-5-BC-80-T-3-F1-J-03-NNN-23-23-24 90R250HF5BC80T3F1J03NNN232324 90R250-HF-5-BC-80-T-4-F1-J-03-NNN-29-29-24 90R250HF5BC80T4F1J03NNN292924 90-R-250-HF-5-BC-80-T-4-F1-J-03-NNN-29-29-24 90R250HF5BC80T4F1J03NNN292924 90R250-HF-5-CD-80-S-4-C8-K-03-NNN-42-42-24 90R250HF5CD80S4C8K03NNN424224 90-R-250-HF-5-CD-80-S-4-C8-K-03-NNN-42-42-24 90R250HF5CD80S4C8K03NNN424224 90R250-HF-5-CD-80-T-3-C8-K-03-NNN-40-40-28 90R250HF5CD80T3C8K03NNN404028 90-R-250-HF-5-CD-80-T-3-C8-K-03-NNN-40-40-28 90R250HF5CD80T3C8K03NNN404028 90R250-HF-5-CD-80-T-3-C8-K-03-NNN-42-42-28 90R250HF5CD80T3C8K03NNN424228 90-R-250-HF-5-CD-80-T-3-C8-K-03-NNN-42-42-28 90R250HF5CD80T3C8K03NNN424228 90R250-HF-5-CD-80-T-3-F1-K-03-NNN-35-35-24 90R250HF5CD80T3F1K03NNN353524 90-R-250-HF-5-CD-80-T-3-F1-K-03-NNN-35-35-24 90R250HF5CD80T3F1K03NNN353524 90R250-HF-5-CD-80-T-4-C8-J-03-NNN-35-35-24 90R250HF5CD80T4C8J03NNN353524 90-R-250-HF-5-CD-80-T-4-C8-J-03-NNN-35-35-24 90R250HF5CD80T4C8J03NNN353524 90R250-HF-5-CD-80-T-4-C8-K-03-NNN-35-35-28 90R250HF5CD80T4C8K03NNN353528 90-R-250-HF-5-CD-80-T-4-C8-K-03-NNN-35-35-28 90R250HF5CD80T4C8K03NNN353528 90R250-HF-5-CD-80-T-4-C8-K-03-NNN-38-38-24 90R250HF5CD80T4C8K03NNN383824 90-R-250-HF-5-CD-80-T-4-C8-K-03-NNN-38-38-24 90R250HF5CD80T4C8K03NNN383824 90R250-HF-5-CD-80-T-4-F1-J-03-NNN-29-29-24 90R250HF5CD80T4F1J03NNN292924 90-R-250-HF-5-CD-80-T-4-F1-J-03-NNN-29-29-24 90R250HF5CD80T4F1J03NNN292924 90R250-HF-5-CD-80-T-4-F1-K-03-NNN-26-26-24 90R250HF5CD80T4F1K03NNN262624 90-R-250-HF-5-CD-80-T-4-F1-K-03-NNN-26-26-24 90R250HF5CD80T4F1K03NNN262624 90R250-HF-5-DE-80-T-3-C8-J-03-NNN-35-35-28 90R250HF5DE80T3C8J03NNN353528 90-R-250-HF-5-DE-80-T-3-C8-J-03-NNN-35-35-28 90R250HF5DE80T3C8J03NNN353528 90R250-HF-5-DE-80-T-3-C8-J-04-NNN-35-35-24 90R250HF5DE80T3C8J04NNN353524 90-R-250-HF-5-DE-80-T-3-C8-J-04-NNN-35-35-24 90R250HF5DE80T3C8J04NNN353524 90R250-HF-5-DE-80-T-3-C8-K-06-NNN-35-35-24 90R250HF5DE80T3C8K06NNN353524 90-R-250-HF-5-DE-80-T-3-C8-K-06-NNN-35-35-24 90R250HF5DE80T3C8K06NNN353524 90R250-HF-5-DE-80-T-4-C8-K-03-NNN-26-26-28 90R250HF5DE80T4C8K03NNN262628。
