Two stage compression technology advantages

The use of two-stage compression to improve the energy efficiency of the compressor is based on the following three main reasons:

◆ One is lower for each level of compression ratio, increase the volumetric efficiency, reduce the each level of internal and external leakage, 2 it is in the mixture of oil and gas in the primary exhaust before entering the secondary suction, can be fully mixed, have the effect of interstage cooling, the more fully mixing of oil and gas mixing station into the compressor secondary compressing, also that the secondary compression process is more close to the isothermal process, improve the energy efficiency of the compressor. The first stage compressor rotor and the second stage compressor rotor are combined in one housing, and are directly driven by helical gear respectively,so that each stage rotor can obtain the best linear speed and the highest compression transfer efficiency.

◆ The compression ratio of each stage of compression is precisely designed to reduce bearing and gear loads. Small compression ratio per stage, smaller leakage, high volume efficiency.

◆ Two-stage compression reduces the compression ratio of each stage, reduces internal leakage, improves volumetric efficiency, reduces bearing load, and improves the life of the main engine.
