汽室涨圈是蒸汽机车阀装置中的一个重要零件。为了提高汽室涨圈的质量和工作的可靠性,我们对汽室涨圈采用了新的工艺。一、新工艺质量良好的汽室涨圈,在经过一系列工艺加工后,在几何形状上应具有最小的椭圆度、最好的内外圆同心度和两侧面的平行度;在机械性能上应具有良好的弹性、磨合性、足够的强度和适宜的硬度。新工艺的基点是,要用尽可能简单的工艺,获得较好的质量。新工艺的各工序列于表1。
Steam chamber ring is an important part of the steam locomotive valve device. In order to improve the quality of the gas cylinder ring and the reliability of the work, we have adopted a new technology for the gas cylinder ring. First, the new process Good quality gas chamber up ring, after a series of processing technology, the geometry should have the least ovality, the best inner and outer concentricity and the parallelism of both sides; in the mechanical properties should be Has good elasticity, running-in, sufficient strength and suitable hardness. The basic point of the new process is to use the simplest possible process to get better quality. The various processes of the new process are listed in Table 1.
