How to determine the compressed air consumption of equipment

To determine the compressed air consumption of the equipment, you can refer to the following two methods:

Method 1: Direct measurement method

1. View equipment nameplates or technical data：
   • Some equipment will mark the compressed air demand on the nameplate or technical data, including air consumption (the volume of compressed air consumed per unit of time) and working pressure.
2. Measure using a flowmeter：
   • Install a flowmeter at the compressed air inlet of the equipment to directly measure the air consumption of the equipment during work.

Method 2: Indirect calculation method

1. Understand the equipment’s duty cycle：
   • Determine the working cycle of the equipment, including the time and frequency at which the equipment uses compressed air during each working cycle.
2. Analyze the gas consumption of equipment：
   • Find out the specific links in which the equipment uses compressed air, such as cylinder action, purging, control valves, etc., and analyze the demand for compressed air in each link.
3. Calculate total air consumption：
   • According to the working cycle of the equipment and the air consumption of each link, calculate the total air consumption of the equipment per unit time.

precautions：

• When determining the amount of compressed air used, it is also necessary to consider the quality requirements of the compressed air, such as oil content, water content, dust content, etc., to ensure that the compressed air can meet the working needs of the equipment.
• For complex compressed air systems, it may be necessary to comprehensively consider factors such as the air consumption of multiple equipment, as well as pressure losses and leaks of compressed air during transportation.
