Air separation equipment compressor is the core component in air separation equipment, mainly used to compress the air in the atmosphere to a higher pressure for subsequent cooling, separation and other treatments, so as to produce industrial gases such as oxygen, nitrogen and other gases.
The compressor draws in and compresses atmospheric air to a high pressure state through the action of mechanical energy. During the compression process, the pressure and temperature of the air are increased, which facilitates the subsequent separation of the different components of the air by means of cooling and separation techniques.
Air separation plant compressors can be divided into various types according to different structures and principles, such as centrifugal compressors, piston compressors, screw compressors and so on. Among them, centrifugal compressors can meet the demand for gas flow and pressure of large-scale air separation equipment due to their high efficiency, stability, easy maintenance and other characteristics. It is widely used in large-scale air separation equipment.
Air separation equipment compressor is one of the core components of the air separation equipment, and its performance directly affects the operating efficiency of the entire air separation system and product quality. Therefore, in the selection and use of air separation equipment compressor, need to fully consider its performance parameters, operational stability, maintenance costs and other factors to ensure long-term stable operation of the air separation system and efficient production.

In medium and large air separation plants, the purification system is an important part when separating oxygen, nitrogen and argon from air. The purification system commonly uses molecular sieve adsorbent to adsorb moisture, carbon dioxide, hydrocarbons, etc. in the air. The molecular sieve purification system plays an important role in the air separation equipment process to ensure safety. The molecular sieve purification system is generally composed of adsorber, electric heater, pipeline, val...

When the exhaust temperature of the piston compressor is higher than the design value, the most direct impact is that the lubricating oil is carbonized, which leads to the compressor parts burned out because of not getting good lubrication. If the temperature of the compressor is too high during actual operation, the cause should be analyzed in time and corresponding preventive measures should be taken. The following methods can be used for reference in practice. 1. Reducing the inlet air temperature can directly reduce the exhaust temperature. Check the intercooler to ensure the cooling effect of the intercooler. 2. The installation of the valve and the selection of the spring should be standardized to ensure the normal operation of the valve and minimize the loss of inlet and outlet pressure. 3. Strengthen the cooling of cylinder to ensure the normal compression process index. 4. Internal leakage is the main reason for the increase of exhaust temperature. 5.For multist
