An air ringmain system is a closed-loop piping system that uses compressed air to transport materials or fluids. It is commonly used in industrial settings for applications such as pneumatic power, ventilation, and cooling.
In an air ringmain system, flow is controlled by pressure differentials between the supply source and the end-use points. Compressed air is pushed through the system by a compressor, and valves and regulators are used to adjust the flow rate at different points along the system.
There are several advantages to using an air ringmain system, including: versatility, as it can transport both solid and liquid materials; energy efficiency, as it requires less energy to move materials compared to other methods; and ease of maintenance, as the system is self-cleaning and does not require frequent repairs.
Flow rate in an air ringmain system is typically measured in cubic feet per minute (CFM) or cubic meters per hour (m3/h). This can be measured using flow meters, which are typically installed at key points along the system.
Several factors can impact flow in an air ringmain system, including: pressure differentials, pipe size and length, obstructions or blockages in the system, and changes in temperature. Proper design and regular maintenance can help mitigate these factors and ensure optimal flow in the system.
