Technical details and manufacturing context for Pressure Compressor

Definition

A pressure compressor is a critical component within pressure/vacuum systems that mechanically compresses gases to achieve higher pressure levels. It functions by drawing in low-pressure gas, reducing its volume through mechanical action (typically via pistons, screws, or vanes), and discharging it at elevated pressure for various industrial applications such as pneumatic control, gas transfer, or process requirements. This directory entry provides reference specifications for a range of pressure compressors used in machinery and equipment manufacturing. The listed parameters—such as rated power from 7.5 to 45 kW, discharge pressure from 0.8 to 1.6 MPa, flow rate from 0.5 to 6.0 m³/min (per ISO 1217), speed from 1450 to 2950 rpm, voltage from 380 to 690 V AC (per IEC 60038), operating temperature from -10 to 40 °C, ingress protection from IP54 to IP65 (per IEC 60529), noise level from 65 to 85 dB(A) (per ISO 2151), weight from 150 to 800 kg, and dimensions from 1200×800×1000 to 2000×1500×1800 mm—are typical ranges that must be confirmed for the specific model and application. Materials on file include cast iron, stainless steel, and aluminum alloy. These compressors operate on positive displacement or dynamic compression principles, as described in the working principle section. For procurement, verify model-specific values and standards with the legal manufacturer or supplier. The standards referenced (ISO 1217, IEC 60038, IEC 60529, ISO 2151) are verification references, not proof of certification or compliance. This entry is part of a neutral product directory and does not imply any endorsement or warranty.

Working Principle

Pressure compressors operate on the principle of positive displacement or dynamic compression. In positive displacement types (like reciprocating or screw compressors), gas is trapped in a chamber where its volume is mechanically reduced, increasing pressure. In dynamic types (like centrifugal compressors), kinetic energy is imparted to the gas via rotating impellers, which is then converted to pressure energy in a diffuser. The compressed gas is then delivered to the system while maintaining pressure stability.
