摘要

带有旋转永磁体(EMP)的电磁感应泵主要用于实验装置,其中操作安全性和可靠性至关重要。与在较高入口压力值下获得的泵相比,当在较低入口压力下操作时,这种泵可能面临流量参数降低。泵的流速增加与泵入口通道的空化过程导致的较低入口压力下的磁转子转速增加不一致。研究的重点是在防止流速增加的严重空化条件下,几个进气道截面的临界空化数。目前的研究是一种利用空化数表征泵运行参数并将其与文献数据进行比较的实验方法。图7,参考文献13。

Experimental cavitation investigation of the electromagnetic PbBi pump with rotating permanent magnets
Electromagnetic induction pumps with rotating permanent magnets (EMP) are used mostly in experimental setups, where operation safety and reliability are crucial. Such pumps can face flow parameter decrease when operating at a low inlet pressure compared with those gained at higher inlet pressure values. The pump's developed flow rate increase does not correspond to the magnetic rotor rotation rate increase at the lower inlet pressure caused by the cavitation process at the pump’s inlet tract. The study focuses on critical cavitation numbers at several inlet tract sections under severe cavitation conditions which prevent the flow rate increase. The current study is an experimental approach to characterize the pump operation parameters using cavitation numbers and comparing them with the literature data. Figs 7, Refs 13.
