At Omenas Air Compressor, understanding the key operational data is essential for maintaining efficiency and maximizing the lifespan of your compressor. In this article, we’ll explain crucial compressor parameters that every user should be familiar with to ensure optimal performance. By applying this knowledge, you can avoid breakdowns, optimize energy consumption, and improve overall performance.

1. Air Compressor Displacement (Flow Rate)

The displacement of an air compressor refers to the volume of air it draws in at its intake per minute, measured in cubic meters per minute (m³/min). It’s important to note that this is the intake air volume, not the amount of compressed air discharged. Displacement is a critical parameter for sizing your compressor to ensure that it can meet your operational needs effectively.

2. Discharge Pressure

Discharge pressure refers to the air pressure at the compressor’s outlet, measured in megapascals (MPa). In the industry, the pressure is often referred to in bar, where 1 bar = 0.1 MPa. The rated discharge pressure, marked on the compressor’s nameplate, indicates the maximum pressure the compressor can safely generate.

Discharge pressure and displacement are two of the most important parameters when selecting the right air compressor for your needs.

3. Air Compressor Discharge Temperature

Discharge temperature is the temperature of the air as it exits the compressor’s head. This parameter is essential for determining the safety and efficiency of your compressor. Factors such as the properties of the compressed air, the quality of lubrication oil, sealing materials, and the gap between rotating parts all contribute to the discharge temperature. Ensuring the right discharge temperature will help maintain compressor safety and reliability.

4. Input Power of the Compressor Unit

The input power of an air compressor is the total power consumed by the compressor, measured in kilowatts (kW). This figure is important for determining energy consumption and ensuring that your power supply can support the operational needs of your air compressor.

5. Specific Input Power

Specific input power is the ratio of the compressor’s input power to its displacement at the rated discharge pressure, expressed as kW/(m³/min). This value is crucial for evaluating the energy efficiency of a compressor, and different models may have varying energy consumption values depending on the pressure at which they operate.

6. Air-Electric Ratio

The air-electric ratio measures how much electrical energy is used to produce one cubic meter of compressed air (converted to intake conditions), with units of kWh/m³. This value is a key metric for assessing the operational efficiency of your air compressor system.

7. Pipeline Diameter Calculation for Compressed Air

When setting up an air compressor system, it’s important to calculate the correct pipeline diameter to prevent excessive pressure loss. The pressure loss in the pipeline should not exceed 5% of the compressor’s operating pressure. Use the following formula to calculate the diameter of the air pipeline:

• D = E/G

Where:

• E = total electrical consumption (kWh)
• G = total air supply in intake conditions (m³)

For pipeline flow speed, keep the following values in mind:

• For a pressure range of 0.1-0.6 MPa, the flow speed should be 10-20 m/s.
• For 0.6-1.0 MPa, the flow speed should be 10-15 m/s.
• For 1.0-2.0 MPa, the flow speed should be 8-10 m/s.

8. Estimating the Air Tank Size

Determining the appropriate size of your air receiver tank is crucial for smooth operation and to avoid unnecessary load on your compressor. The standard recommended sizes, according to JB/T8867, are available for various air volumes. For example:

• If the compressor’s output is less than 6 m³/min, the minimum receiver volume should be 0.2 times the compressor output (Vc = 0.2Q).
• For outputs between 6 and 30 m³/min, use a factor of 0.15 (Vc = 0.15Q).
• For outputs greater than 30 m³/min, use a factor of 0.1 (Vc = 0.1Q).

9. Improving Compressor Capacity When Discharge Pressure Is Inadequate

If your compressor is not achieving the required discharge pressure, you may need to increase its displacement. The formula for calculating the additional displacement required involves factors such as compressor rated displacement, the required discharge pressure, and the flow speed in the pipeline. Proper adjustments to the air receiver tank’s minimum volume (Vc) can also help optimize system performance.
