?1、液壓泵的工作壓力不得超過其允許工作壓力的6倍 工作壓力太高時(shí)，可能會(huì)引起泵的嚴(yán)重?fù)p壞，甚至造成事故因此，必須保持液壓泵的正常工作泵件與工作部件的密封面與表面應(yīng)保持清潔使用前應(yīng)檢查密封面是否有損壞、裂縫、漏氣以及泄漏的現(xiàn)象。
安裝前確認(rèn)壓力表的指示方向正確在手動(dòng)泵運(yùn)行時(shí)，液壓泵在額定壓力下運(yùn)行一段時(shí)間后，如發(fā)現(xiàn)壓力有波動(dòng)（或壓力降低）時(shí)要立即停止泵送，確認(rèn)原因后進(jìn)行維修手動(dòng)泵安裝時(shí)應(yīng)注意檢查液壓表指示的最高壓力是否在2mpa以上，若工作壓力超過2mpa時(shí)應(yīng)停機(jī)再接液壓泵，并停止輸送混凝土。
2、嚴(yán)禁拆裝和調(diào)整泵 在拆卸和調(diào)整時(shí)，應(yīng)先切斷動(dòng)力后拆卸拆卸過程中，應(yīng)切斷電源、拆除齒輪軸承蓋及連桿拆下連桿后應(yīng)當(dāng)將連桿卸下來用手扳住卡子、擰緊螺母然后將活塞桿下端裝上缸套內(nèi)的油缸套套上或裝上閥體與柱塞套；調(diào)整時(shí)應(yīng)先擰緊卡子上的螺紋再調(diào)整閥體與柱塞套的接觸面；活塞桿上的密封圈不能卸下前應(yīng)卸掉前緣的密封圈；重新安裝上活塞桿將泵體調(diào)節(jié)到位；將活塞桿上的導(dǎo)向環(huán)卸下后將活塞桿壓下固定在柱塞頭上（油缸套不能卸);安裝閥體和連桿時(shí)應(yīng)使活塞桿上沒有墊圈；在調(diào)整柱塞頭后將接觸面擦凈即可進(jìn)行正常工作。
檢查及調(diào)整完畢后重新安裝連桿和彈簧等部位均需要在操作前充分調(diào)整好再進(jìn)行施工 3、液壓系統(tǒng)要保持清潔，必要時(shí)采用防腐防銹處理 工作前檢查各油路中油位是否符合標(biāo)準(zhǔn)；油缸間隙是否符合要求；泵機(jī)接頭密封是否良好；泵送管中是否有堵塞物；管路是否堵塞？各連接處是否有漏氣現(xiàn)象？注意各部件工作間隙是否正常控制液壓系統(tǒng)中的各個(gè)元件的工作是否正常。
柱塞泵屬于液壓缸，由柱塞泵凸輪軸帶動(dòng)活塞產(chǎn)生往復(fù)運(yùn)動(dòng)工作時(shí)可由凸輪軸帶動(dòng)活塞運(yùn)動(dòng)來實(shí)現(xiàn)輸送作用 90R130-MA-5-NN-80-R-3-F1-F-C5-GBA-26-26-24-P000 90R130MA5NN80R3F1FC5GBA262624P000 90-R-130-MA-5-NN-80-R-3-F1-F-C5-GBA-26-26-24-P000 90R130MA5NN80R3F1FC5GBA262624P000 90R130-MA-5-NN-80-R-3-F1-F-C5-GBA-35-35-24 90R130MA5NN80R3F1FC5GBA353524 90-R-130-MA-5-NN-80-R-3-F1-F-C5-GBA-35-35-24 90R130MA5NN80R3F1FC5GBA353524 90R130-MA-5-NN-80-S-3-C8-F-C6-GBA-35-35-24 90R130MA5NN80S3C8FC6GBA353524 90-R-130-MA-5-NN-80-S-3-C8-F-C6-GBA-35-35-24 90R130MA5NN80S3C8FC6GBA353524 90R130-MA-5-NN-80-S-3-C8-H-C5-GBA-26-26-30 90R130MA5NN80S3C8HC5GBA262630 90-R-130-MA-5-NN-80-S-3-C8-H-C5-GBA-26-26-30 90R130MA5NN80S3C8HC5GBA262630 90R130-MA-5-NN-80-S-3-C8-H-C5-GBA-35-35-30 90R130MA5NN80S3C8HC5GBA353530 90-R-130-MA-5-NN-80-S-3-C8-H-C5-GBA-35-35-30 90R130MA5NN80S3C8HC5GBA353530 90R130-MA-5-NN-80-S-3-C8-H-C5-GBA-42-42-24 90R130MA5NN80S3C8HC5GBA424224 90-R-130-MA-5-NN-80-S-3-C8-H-C5-GBA-42-42-24 90R130MA5NN80S3C8HC5GBA424224 90R130-MA-5-NN-80-S-3-F1-F-C5-GBA-42-42-24 90R130MA5NN80S3F1FC5GBA424224 90-R-130-MA-5-NN-80-S-3-F1-F-C5-GBA-42-42-24 90R130MA5NN80S3F1FC5GBA424224 90R130-MA-5-NN-80-S-4-C8-F-C4-GBA-29-29-24 90R130MA5NN80S4C8FC4GBA292924 90-R-130-MA-5-NN-80-S-4-C8-F-C4-GBA-29-29-24 90R130MA5NN80S4C8FC4GBA292924 90R130-MA-5-NN-80-S-4-C8-H-C5-GBA-23-23-24 90R130MA5NN80S4C8HC5GBA232324 90-R-130-MA-5-NN-80-S-4-C8-H-C5-GBA-23-23-24 90R130MA5NN80S4C8HC5GBA232324 90R130-MA-5-NN-80-S-4-C8-H-C5-GBA-29-29-24 90R130MA5NN80S4C8HC5GBA292924 90-R-130-MA-5-NN-80-S-4-C8-H-C5-GBA-29-29-24 90R130MA5NN80S4C8HC5GBA292924 90R130-MA-5-NN-80-S-4-F1-F-C5-GBA-23-23-24 90R130MA5NN80S4F1FC5GBA232324 90-R-130-MA-5-NN-80-S-4-F1-F-C5-GBA-23-23-24 90R130MA5NN80S4F1FC5GBA232324 90R130-MA-5-NN-80-S-4-F1-F-C5-GBA-42-42-24 90R130MA5NN80S4F1FC5GBA424224 90-R-130-MA-5-NN-80-S-4-F1-F-C5-GBA-42-42-24 90R130MA5NN80S4F1FC5GBA424224。
