软管泵路面抛丸机口碑好实力强

众所周知软管泵在运行时，是通过一根U型附有弹性的橡胶软管来完成输送。今天小编需要强调的是，软管存放时间不宜过长，一般以一年为限。在停工期间，对装有软管的泵，若长期不用，每隔一个月需转动泵一次。以免压辊长时间压在泵管的某一处，减弱管子回弹性，影响其流量的输送。

It is well known that when the hose pump is running, it is conveyed through a U-shaped rubber hose with elasticity. Today the editor needs to emphasize that the storage time of the hose should not be too long, and it is generally limited to one year. During the shutdown period, if the pump is equipped with a hose, if it is not used for a long time, the pump needs to be rotated every other month. So as not to press the roller for a long time at a certain position of the pump tube, it will weaken the resilience of the tube and affect its flow rate.

 

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预防发生孔内事故。！
