Investigation on Pneumatic Quantitive Conveying of Liquid Magnesium
In order to realize the pneumatic quantitive conveying of liquid magnesium,a hydraulic simulation device was designed.The influences of gas pressure and pressurization time on the hydraulic conveying volume were investi-gated by physical simulation,and mathematical model for controlling the conveying volume was established.Accord-ing to the similarity principle,the magnesium alloy conveying apparatus was designed to achieve the quantitative con-veying of liquid magnesium by controlling the pressurization time under constant pressure.The results indicate that quantitative conveying is realized based on timing quantitative method without splashing during the conveying process,and the average error of revised prediction model is 1.5%,meeting the requirements of quantitive conveying.
