Influencing factors of flow rate of electromagnetic pump used to aluminum alloy quantitative pouring

摘要

The effects of electric current, the altitude of the liquid outlet and liquid level change within crucible in direct-current electromagnetic pump (EMP) used to quantitative pouring of aluminum alloy on flow rate were studied. The results show that the effects of electric current on flow rate is affected by the hydraulic resistance; flow rate decrease with the increasing of the altitude of liquid outlet; when the output of aluminum alloy is large, the liquid level change within crucible have a significant impact on flow rate.
