软管泵性能<br />
软管泵性能的两个主要参数为排量和压力。排量以每分钟排出若干升计算?它与钻孔直径及所要求的冲洗液自孔底上返速度有关，即孔径越大，所需排量越大。要求冲洗液的上返速度能够把钻头切削下来的岩屑?岩粉及时冲离孔底，并可靠地携带到地表。地质岩心钻探时一般上返速度在0.4～1米/分左右。<br />泵的压力大小取决于钻孔的深浅冲洗液所经过的通道的阻力以及所输送冲洗液的性质等。钻孔越深管路阻力越大、需要的压力越高。随着钻孔直径，深度的变化，要求泵的排量也能随时加以调节。在泵的机构中设有变速箱或以液压马达调节其速度、以达到改变排量的目的。为了确掌握泵的压力和排量的变化软管泵上要安装流量计和压力表，随时使钻探人员，解泵的运转情况同时通过压力变化判别孔内状况是否正常以发生孔内事故。！

软管泵的工作原理及应用：软管在泵体内呈U形布置。当旋转体带动挤压轮旋转时，挤压软管受到挤压轮的挤压而发生弹性变形，然后吸入口形成负压吸浆。通过挤压轮的推动，浆液从出料口排出，形成浆液的压力输送。工业软管泵主要应用于建筑、地下工程、矿山、食品、造纸、陶瓷等领域的粘性浆液远距离输送、计量泵送、压力灌浆、喷射等。  

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.
