clearance volumetric efficiency

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。
