更換泵管操作步驟：
將連接泵進出口的管道拆開，并將冷卻液放出。將進出口管夾內六角螺栓（各四個）擰下。短接管及管卡取出。將進出口前接管螺栓旋出，將前接管、壓環及密封圈取出。啟動電機，使電機順時針旋轉，將軟管拉出。啟動電機，使電機逆時針旋轉。將新軟管一側涂少量潤滑脂（黃油），然后將涂有潤滑脂的一側向泵殼壁，從泵殼上方插入至泵殼中，直至軟管到泵殼下方出口的合適位置，停電機。將密封圈套至軟管下口泵接管內，將壓環裝入，擰緊前接管螺栓，裝入管夾，擰緊管夾螺栓。啟動電機，使電機逆時針旋轉，用手或橡膠板堵住軟管上方口，軟管全自行進入泵中，通過泵側面窗口觀察，使軟管貼到泵殼內壁，停電機，按固定的方式將軟管安裝好。填加冷卻液，軟管更換即告完成。

軟管泵的工作原理及應用：軟管在泵體內呈U形布置。當旋轉體帶動擠壓輪旋轉時，擠壓軟管受到擠壓輪的擠壓而發生彈性變形，然后吸入口形成負壓吸漿。通過擠壓輪的推動，漿液從出料口排出，形成漿液的壓力輸送。工業軟管泵主要應用于建筑、地下工程、礦山、食品、造紙、陶瓷等領域的粘性漿液遠距離輸送、計量泵送、壓力灌漿、噴射等。  

Working principle and application of hose pump: The hose is arranged in a U-shape in the pump body. When the rotating body drives the extrusion wheel to rotate, the extrusion hose is elastically deformed by the extrusion wheel, and then the suction port forms a negative pressure suction slurry. By the push of the squeeze wheel, the slurry is discharged from the discharge port, forming a pressure transfer of the slurry. Industrial hose pumps are mainly used for the long-distance transportation of viscous slurry in the fields of construction, underground engineering, mining, food, papermaking, ceramics, metering pumping, pressure grouting, spraying, etc.
