The main reasons why the screw machine is not suitable for use in flammable and explosive gases are as follows:
Working Principle and Security Risks:
The working principle of the screw machine is to compress the gas by the rotation of the screw. In this process, the gas is highly compressed and generates heat.
If the compression is a flammable or explosive gas, then this compression and the heat generated may trigger the combustion or explosion of the gas, resulting in a serious safety accident.
Effect of temperature and pressure:
The screw machine generates higher temperatures and pressures during the compression process.
Flammable and explosive gases can become extremely unstable at a certain temperature and pressure, which can easily cause explosions.
Therefore, the use of a screw machine to compress flammable and explosive gases will greatly increase the risk of explosion.
Equipment Design and Safety Standards:
Screw machines are often designed to meet safety standards for handling flammable and explosive gases.
To ensure safety, specialized explosion-proof equipment requires special designs and materials to prevent potential explosion risks. Ordinary screw machines do not have these special designs.
In summary, due to the working principle of the screw machine, the temperature and pressure changes generated, and the equipment design considerations, it is not suitable for compressing flammable and explosive gases. The use of screw machines to process this type of gas poses a high safety risk. Therefore, when selecting compression equipment, a reasonable choice must be made based on the nature of the gas and the safety requirements.
