1976年第二季度,我们初步试验用塞焊方法制造了一个窄流道离心式压缩机的叶轮。经超速试验表明,质量良好,现将叶轮的焊接总结如下。 HL-200/8型离心式压缩机四级叶轮的外径为325毫米,外元线速度为 280.63米/秒,选择材料为 33CrNi3Mo,设计尺寸见图1。
In the second quarter of 1976, we initially tested the impeller of a narrow-flow centrifugal compressor with a plug-in method. After speeding test showed that good quality, now the impeller welding summarized as follows. HL-200/8 centrifugal compressor four impeller outer diameter of 325 mm, the outer line speed of 280.63 m / s, the choice of materials for 33CrNi3Mo, design size shown in Figure 1.
