永邦两级压缩空压机节能原理及效果
Energy saving principle and effect of Yong Bang two stage compressor
相对于单级压缩，两级压缩趋近于最省功的等温压缩，从原理上，两级压缩比单级压缩节能10%以上。
采用两级压缩主机，就是采用大小不同的两组螺杆转子，实现合理的压力分配，降低了每次压缩的压缩比，减少了压缩过程产生的热量。
根据压缩机的工作原理，等温压缩是的。压缩两级之间采用了润滑油喷淋式降温、冷却效率高，达到等温压缩降低压缩功耗。
两级压缩空压机节能效果
1.每一级的压缩比小(泄露减少)节能 2~5%
2.级间冷却(恒温压缩)节能5~8%
3.配置高能效电机 节能2~4%
