摘要
普通屏蔽泵效率低、气隙要求严,为此提出把永磁屏蔽电动机、屏蔽套和离心泵设计为一体的永磁转子屏蔽泵。主要介绍了永磁体的选择、磁路设计、屏蔽套损耗分析,并以额定功率为5.5 kW的永磁屏蔽电动机为例,计算永磁电机的各参数及性能。经与试验结果对比达到设计要求,证明设计方法可行。
The efficiency of ordinary canned pump was low and a strict air-gap was requested.Therefore,Permanent magnet canned pump was put forward which designed to permanent magnet canned motor,housing and centrifugal pump.This paper mainly introduced choice of permanent magnets,Magnet circuit design,analysis and calculation of waste of housing.Taking a permanent magnet canned motor with rated power 5.5 kW for example,the parameters and performance of permanent magnet canned motor were calculated.The design demand w...
