By the gases at high pressure of two-stage compression, the operating efficiency of compressor is substantially increased, in addition, being found out by following formula process：
Gas enters from a-1 chambers, and under the driving of hydraulic oil drive system, piston rod is moved upwards, by the gas in a-1 chambers
Body press-in b-1 chambers, due to a-1 chambers piston-rodless, therefore the volume in a-1 chambers is more than b-1 chambers, this creates the terminal one stage of compression（Pressure
Contracting is than being more than 1）, while the gas in b-2 chambers enters c-2 chambers, and by changing the cross-sectional area of piston rod 2 and cylinder in c-2 chambers
Diameter, is allowed to smaller than volume in b-2, so as to produce two-stage compression（Compression ratio is more than 1）, compressed gas from c-2 chambers discharge, with
This is while a-2 chambers air-breathing.Similarly, piston rod is moved downward, by a-2 gases press-in b-2 chambers, due to a-2 chambers piston-rodless, therefore a-
The volume in 2 chambers is more than b-2 chambers, this creates the terminal one stage of compression（Compression ratio is more than 1）.B-1 gases enter c-1 chambers simultaneously, and
By changing the cross-sectional area of piston rod 2 and cylinder diameter in c-1 chambers, it is allowed to smaller than volume in b-1, so as to produce two-stage compression
（Compression ratio is more than 1）, compressed gas discharge from c-1 chambers, at the same time a-1 chambers air-breathing.And so on circulate, you can realize continuous
Discharge the gases at high pressure of two-stage compression.
Compression ratio in three gas compression rooms of top is calculated：
The compression ratio δ 1 of one stage of compression：δ1=A1/A2=π（D1/2) 2H/ π { (D1-d1)/2 } 2H
Due to D1 ＞ (D1-d1)
So the ＞ 1 of δ 1
The compression ratio δ 2 of two-stage compression：δ 2=A2/A3=π { (D1-d1)/2 } 2H/ π { (D2-d2)/2 } 2H
Due to D1>D2, d2>D1, it can be deduced that (D1-d1) ＞ (D2-d2),
So the ＞ 1 of δ 2
Wherein, compression travel：H is the displacement of piston in compression process；A1 is the volume in a-1 chambers；A2 is b-1 chambers
Volume；A3 is the volume in c-1 chambers.
Similarly, the gas compression room of lower section can also carry out two-stage compression, and the size of certain compression ratio can adjust cylinder diameter
With diameter of piston rod size, adjustment difference determination.
