The features about two techniques of honing process of cone-shaped cylinder hole

本文主要介绍了冰箱往复式压缩机气缸座锥形缸孔两种珩磨形式工艺技术特点:珩磨头连续往复冲程式粗、精珩磨锥形缸孔、多根珩磨头顺序铰珩锥形缸孔。经过对比分析及工艺试验,铰珩锥形缸孔质量比较稳定,并已实施,效果良好,锥形缸孔质量完全满足了压缩机要求,压缩机性能COP值提升了0.02~0.03。

This article mainly introduces the features about two techniques of honing process of cone-shaped cylinder hole, which is widely used for cylinder block in refrigerator reciprocating compressor. One is rough and finish honing of cone-shaped cylinder hole with continuous reciprocating stroke, the other is cone-shaped cylinder hole with sequential reaming and honing. Through the comparison and experiment analysis, the cone-shaped cylinder hole with reaming and honing is strong for reliable quality and good performance. Furthermore, its method of process fully meets the requirements of the compressor and improves Coefficient of Performance(COP) of the compressor from 2 percent to 3 percent.
