Operations and Maintenance

The stable operation of high-efficiency screw compressor units depends on a scientifically sound maintenance schedule. This paper provides a detailed overview of the specific tasks and operational guidelines for daily inspections, monthly and quarterly routine maintenance, and annual…

The discharge pressure of an air compressor should not be set arbitrarily based on experience; it should be capped at the equipment’s nameplate‑rated discharge pressure, the system’s design pressure, and the allowable pressure at the point of use.…

This paper reviews the fundamental design codes for compressed air compressor stations, focusing on key aspects such as station layout, ventilation and heat dissipation, piping configuration, electrical control systems, safety and fire protection, and commissioning and maintenance. It…

This article focuses on the nameplate parameters of air compressors, explaining the meanings of key specifications such as rated displacement, discharge pressure, power, and rotational speed. It analyzes how operating conditions, load, ambient environment, and maintenance influence the…

This article explains the fundamental concept of screw compressor rotor speed, examines how factors such as the motor, drive type, load, cooling, and maintenance influence this speed, and, in conjunction with air delivery rate, energy consumption, and operational…

An OP value of 53% indicates that the air compressor spends approximately half its operating time under load, which falls below the recommended efficiency range of 65%–85%. This may point to issues such as uneven air demand, improper…
