不同工况下合成氨循环压缩机叶轮数的确定

Determination of Number of Impellers in Ammonia Circulator under Various Work Conditions

通过对合成氨循环压缩机透平机组运动部件进行受力分析,确定不同工况下适宜的叶轮数。通过改造,改善了机组自身平衡条件,每减一级叶轮可节电约10%左右,经济效益明显。

By analyzing the stress on the moving parts of the ammonia circulator-turbine unit the appropriate number of impellers is determined under various work conditions. Through retrofit, the equilibrium condition of the unit itself is improved, and every reduction in the number of impellers at a stage saves about 10% in power, with remarkable economic benefit.
