Precision Constant Current DC Power Supply
Air Volume Test Bench
Air Volume Test Bench
Features
• It can accurately measure the air pressure-dry air volume and power-dry air volume performance curves of fan rated air volume, fan coil unit, axial flow fan, cross flow fan, centrifugal fan and other forms of fan with air conditioner housing.
• Using fan exhaust measurement, wind chamber wind tunnel test method, high degree of automation, all stainless steel custom, beautiful appearance generous, long service cycle. Double-sided seamless welding treatment, sealed, high measuring accuracy.
• The equipment automation degree is high, each equipment start and stop, working condition and flow adjustment are automatically adjusted to complete. Greatly shorten the detection cycle, energy saving and consumption reduction. The equipment runs stably, the failure rate is low, the maintenance is simple.
• The accuracy of all measurement parameters without modification is higher than the requirements of relevant national standards, the data measurement is real, there is no data error fluctuation, and the deviation of comparison results with national laboratories is not more than 3%.
Control System Description
• The equipment through the nozzle method to measure the size of fan ventilation, wind tunnel adopts φ40×1+φ50×1+φ70×1+φ80×1 nozzle combination, 100-1500m³/h accuracy can reach within 1%. The measured minimum air volume is 100m³/h, and the measured maximum air volume is 1500m³/h.
• The air volume test system includes: air chamber box, uniform flow hole plate, flow nozzle, static pressure taking device, auxiliary frequency conversion fan, etc.
• The air volume of the fan is calculated automatically by measuring the pressure difference between the front and rear of the nozzle. The static pressure of the system is measured by connecting the micro pressure gauge to the pressure inlet.
• Adopt microcomputer automatic control, can synchronously record and print the original data, display the process control curve, print the original data report, automatically generate the calculation results and so on.
