Effect of Laser Suspension Height of Electromagnetic Pump for Casting on Quantitative Accuracy
From the mechanism analysis of quantitative pouring system of electromagnetic pump used for casting, the experimental study and theoretical analysis of constant parameter method, volume compensation method and suspension height method were conducted, respectively. Then the suspension height was measured by metal probe, ceramics probe and laser rangefinder respectively, and the influence of various methods in experimental research on quantitative accuracy and stability was analyzed. The results show that the quantitative suspension height method is the best quantitative plan in the unsteady quantitative output. And the suspension height of laser ranging method can improve the quantitative accuracy greatly.
