到目前为止,对离心泵抽送渣浆时的性能研究工作,主要集中在渣浆参数对泵性能的影响,如颗粒粒径、浓度对泵的扬程、流量和功率的影响,对泵性能随磨损发展的研究很少.但实际上磨损对泵性能有很大的影响,如叶轮磨损后泵的扬程下降,流量减低,泵的运行效率也会降低.泵在现场运行时,操作人员一般根据泵送的流量或电表显示的电流来判断泵的继续使用与否.我们认为对泵性能随磨损的发展研究是十分重要的,而且对渣浆泵的现场运行具有一定的指导意义.为此,我们进行了渣浆泵在受损过程中性能变化的实验.
So far, the performance research on centrifugal pump pumping slurry mainly focuses on the influence of slurry parameters on the pump performance, such as particle size, concentration of the pump head, flow and power, the pump performance with wear and tear The development of research is very little.But in fact, wear and tear on the pump performance has a great impact, such as impeller wear pump down the head, flow rate decreases, the pump operating efficiency will be reduced.Pump running in the field, the operator generally based on the pump Send flow or meter current to determine whether the continued use of the pump.We believe that the development of pump performance with the wear and tear is very important, and the slurry pump on-site operation has some guidance.To this end, we An experiment was conducted on the performance change of the slurry pump during the damage process.
