Double - stage compression screw machine: how to work double - stage compression screw machine
At present, in the screw air compressor on the market, there are mainly two kinds of single-stage compression and two-stage compression. Single-stage compression is more familiar to everyone and widely used. In actual use, some air compressors with large power and large gas production demand often use two-stage compression screw machine.
In essence, the double stage compression screw machine combines the compression rotor in a housing and drives directly through the helical gear respectively. The natural air of the two-stage compression screw machine enters the compression through the air filter, and is mixed with a small amount of lubricating oil in the compression chamber, and the mixed gas is compressed to the interstage pressure. The gas compressed by the two-stage compression screw machine enters the cooling channel and contacts with a large amount of oil mist, thus greatly reducing the temperature. The cooled compressed gas is recompressed to the exhaust pressure.
Double - stage compression screw machine in the compression process isothermal compression is very saving work. Not only that, isothermal compression can not only reduce the consumption of work, but also reduce the temperature of the gas after compression, so that the use of two-stage compression screw machine material is more broad and economic, so that the operation of two-stage compression screw machine is more reliable.
In addition, the two-stage compression screw machine two pairs of rotor work at the same time, pumping speed, gas production, which is the irreplaceable advantage of single-stage compression. And because the compression of each stage of the two-stage compression screw machine is much smaller than the single-stage compression, the rotor and bearing are compressed by small, coupled with the diameter of the rotor, low speed, so the two-stage compression screw machine is more reliable.
