?1、泵缸內有無異物或破碎物 將螺母旋入或拔出螺母與泵上的螺釘不得擰得過緊或擰得過松螺母與泵缸的間隙應為0.1-0.20mm,以防發生飛濺和磨損影響泵效率或導致泵工作不穩定將泵入液體放盡注意觀察壓力和流量，并用軟管向管道內加注液壓油。
將泵葉插入或抽出葉片孔時，必須將葉輪放在孔內或支架上保持泵葉在工作中在使用中應隨時觀察液面是否下降、溢流槽是否堵塞、液面高度是否與作業高度一致等情況 2.定期檢查管道接口是否堵塞 要經常清理管路接口內的雜質。
應定期檢查管路接頭內的密封面是否被破壞要經常檢查連接接頭內的密封墊是否被磨損如發現密封墊磨損、泄漏量過大，必須及時更換要經常注意管路接頭密封圈（端面）是否有裂紋，如有裂紋或龜裂，應及時處理如果膠圈開裂或裂紋較深，必須及時更換。
應經常檢查液壓管路接頭密封墊安裝是否到位，松動處是否正確涂以黃油或煤油保持良好潤滑狀態；檢查液壓管路接頭密封墊處密封效果是否良好；檢查各部位螺釘螺栓連接是否牢固；檢查油泵是否運轉正常；檢查各液壓閥、接頭內閥塞是否漏油后及時加以修理或更換；檢查接頭密封是否嚴密、密封是否完好、密封面是否有損壞或脫膠現象等；檢查各部位螺栓密封間隙是否符合要求；各部位螺釘是否松動等；在使用過程中要注意防止設備意外移動而造成的傷害；定期檢查液壓管路接頭密封圈以及液壓油中油量及油質和泵送介質質量、壓力及其管道內壁清理液面等工作情況。
