General fuel injection screw air compressor is only a single-stage compression, but also to achieve the normal power system exhaust pressure and other normal use. But from the point of view of energy consumption and power use, two stage compression can effectively reduce energy consumption, thus bringing higher power and gas value. To this end, in the 90kw~250KW fuel injection screw air compressor, the introduction of energy-saving two stage compressed screw air compressor.
What is the two stage compression, which compresses the natural air through the air filter and enters the first stage compression, mixing with a small amount of lubricant in the compression chamber, while compressing the mixture to the interstage pressure. The compressed gas enters the cooling channel, with a large amount of oil
Fog exposure, which greatly reduces the temperature. The cooled compressed gas enters the second stage rotor and is subjected to a two stage compression, which is compressed to the final exhaust pressure. Finally, the compressor is discharged through the exhaust flange to complete the whole compression process.
Two stage compression type energy-saving injection screw air compressor at the same power, comparable to single-stage compression of fuel screw air compressor, more than 10%-20% gas. In other words, under compression equal gas, the two stage compression can save 15% of the power compared to the single-stage compression.
The high-end energy-saving two stage compression injection screw air compressor is not only more energy-saving than single stage fuel injection screw air compressor. Moreover, because of lower compression ratio, lower rotor and bearing force, larger rotor diameter and lower rotating speed, the operation is more reliable. not only
It has all the advantages of single-stage fuel injection screw air compressor. Moreover, it has more advantages than other brands of two stage compression injection screw air compressor.
Two stage compression type energy-saving injection screw air compressor has unique host design.
It combines a first stage compression rotor with a two stage compression rotor in a single casing and drives directly through each gear to obtain the optimum linear speed for each stage of the rotor
The compression efficiency is higher. Compared to the single-stage compression, isothermal compress level two reported to the provincial power compression, in principle, two level than the single-stage compression energy saving 5~8%, using two stage compressor, is the use of two groups of screw rotors of different sizes, realize the reasonable distribution of pressure, reduce the time compression ratio, low compression ratio and even a special advantage: one is to reduce the leakage, improve the volumetric efficiency; the other is a greatly reduced the bearing load, improve the bearing life, prolong the service life of the host
