Air Compressor Intake Pressure and Exhaust Pressure: Understand Key Operating Parameters

What are intake pressure and exhaust pressure?

Intake pressure refers to the ambient atmospheric pressure at the suction end of the air compressor (usually about 0.1 MPa, that is, one standard atmospheric pressure), which is affected by altitude, temperature and intake air filtration. Exhaust pressure is the pressure value of compressed air output, also knownworking pressure, is the core index of the actual air supply capacity of the air compressor.

Relationship between differential pressure and system performance

differential pressure(Exhaust pressure-intake pressure) directly reflects the power intensity of the compressor. Excessive pressure difference may aggravate component wear and reduce energy efficiency; Too small pressure difference may lead to insufficient gas supply. Reasonable control of pressure difference is helpful to prolong the service life of equipment and ensure stable gas supply.

The necessity of paying attention to compressor operating parameters

• regular monitoring of intake and exhaust pressure can timely detect problems such as filter plug and valve leakage.
• Exhaust pressure setting should match the requirements of terminal gas equipment to avoid excessive energy consumption or insufficient pressure.
• The decrease of intake unnormal formation pressure (such as intake tube bending and dirty filter blocking) will directly affect the exhaust volume and efficiency.
