Experimental research on the influence of clearance volume of 4M12 oxygen piston compressor upon discharge capacity and power consumption;
4M12活塞式氧压机气缸余隙容积对排气量和功耗影响的试验研究
In present,the refrigerating coefficient of reciprocal refrigerating compressor is low,the refrigeration compressor clearance volume is changed through the changes of valve board thichness.
针对目前往复式制冷压缩机存在着制冷系数较低等问题,通过改变阀板的厚度来改变往复式制冷压缩机的余隙容积,从而提高往复式制冷压缩机的制冷系数,并进行了试验研究。
In another method,residual area of indentation can be obtained by atomic force microscope(AFM),and hardness is determined by residual area and peak load.
在对材料微纳米硬度测试中,可利用纳米压痕方法得到载荷-位移曲线,并用相关算法得到接触面积和硬度值;也可通过原子力显微镜测出压痕残余面积,由残余面积和最大载荷得到材料的硬度值。
