Pressure control

The core of variable-frequency air compression lies in using a pressure sensor to measure discharge pressure, with the controller and inverter adjusting the motor’s supply frequency. This allows the motor speed to vary in response to air demand,…

This paper delves into the fundamental relationship between compressor relief devices and design pressure. As a critical safety‑protection component, the relief device’s primary function is to ensure that the compressor’s operating pressure remains strictly within the design‑pressure limits.…

In the operation of screw refrigeration machines, there is a direct interrelationship between discharge pressure and liquid‑supply pressure. Typically, an increase in discharge pressure results in a corresponding rise in liquid‑supply pressure, as both occur on the high‑pressure…

This paper examines the key aspects of pressure management for refrigerant dryers within the Chongqing power system. It provides a detailed analysis of how critical technical parameters—such as operating pressure and pressure dew point—affect equipment performance, and underscores…
