How does the two-stage compression screw air compressor save energy?
其实二级压缩就是把一级压缩转子和二级压缩转子组合在一个机壳内，并分别通过斜齿轮直接传动。自然空气通过空气过滤器进入第一级压缩，在压缩腔与少量润滑油混合，同时将混合气体压缩到级间压力。压缩后的气体进入冷却通道，与大泥杆 保定空压机 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修 托辊设备 托辊生产线
In fact, the two-stage compression refers to the combination of the
first stage compression rotor and the second stage compression rotor in a
casing, which are directly driven by helical gears respectively.
Natural air enters the first stage of compression through the air
filter, mixes with a small amount of lubricating oil in the compression
chamber, and compresses the mixed gas to the interstage pressure at the
same time. The compressed gas enters the cooling channel and contacts
with a large amount of oil mist, which greatly reduces the temperature.
The cooled compressed gas enters the second stage rotor for secondary
compression and is compressed to the final exhaust pressure. Finally,
the compressor is discharged through the exhaust flange to complete the
whole compression process.
