Advantages And Disadvantages Of Multi-stage Compression What is a multi-stage compression? The so-called multi-stage compression, that is, depending on the desired pressure to the cylinder of the compressor is divided into several stages, progressively increasing the pressure. And the establishment of the inter cooler after each compression stage, each stage of cooling the high temperature gas after compression. This can reduce the exhaust temperature of each stage. Why multi-stage compression?

Single-stage compressor to a high pressure of the gas pressure must increase the compression ratio, the temperature of the compressed gas will rise very high. Greater than the gas pressure increases, the gas temperature rise even higher. When the end of the temperature and pressure ratio exceeds a certain value, the gas will be compressed more than the general compressor lubricants flash point (200 ~ 240 ℃), oil will be burned carbon residue, causing lubrication difficulties. Multi-stage compression advantages: 1. A saving power consumption 2. Improve the utilization of the volume of the cylinder Tel.: +86-516-83057556 Email: [email protected]

Nanjing Standen Mechanical Equipment Technology Co., Ltd 3. reduces exhaust temperature 4. reduce the role of the force on the piston rod gas Disadvantages of the multi-stage compression; 1. An increase in the complexity of the compressor body; 2. consumed in increased piping, equipment, valves in the resistance loss; 3. manufacturing costs and operating costs increased significantly.
