ME can provide accurate and repeatable airflow, pressure, and power data for fans by performing an airflow measurement test per AMCA standards. The test pipe can accommodate airflow rates cubic feet per minute and static pressures.
Six traverse Points in a round duct at the testing section along six pitot testing sensors with four radial locations to be averaged for measuring both static and dynamic pressures. The throttling plates (8 plates with different throttling radius) are used to block air flow in order to increase the static pressure and construct the static pressure versus flow rate curve. The star type was selected. It consists of 8 equal plates separated with an angle of 45 degrees and welded together to be installed at the settling pipe after inlet for straightening the flow.
Also, 9 transition conical connection pipes are designed and available for integration with the main pipe to test several fan diameters from 450 mm up to 1250 mm considering the mitigation for turbulent flow based on AMCA constraints.
A series of flow sensors from Dwyer company, pressure transducers and temperature sensors are integrated along with the test rig to sense and scan the pressures, velocities and temperatures along the facility.
A software data acquisition was developed to ensure accurate recorded data and post-processing of the recorded data takes place with a calculated uncertainties based on the AMCA-210 testing constraints.
According to the ISO 10816, 1940-2 and 14694.SPM device was integrated with a test facility stand-alone for measuring the dynamic balancing for rotors. SPM device is used to assure accurate balancing and vibration analysis for all manufactured rotors. SPM device is capable of measuring modes, recording, measuring rounds, display windows, spectrum functions, and order tracking. Measurement techniques always included RPM, temperature, vibration, and stethoscope. Also, Shock pulse measurement SPM HD, SPM dBm/dBc, SPM HR/LR, SPM LR/HR HD and SPM Spectrum Vibration measurement ISO 10816 vibration, HD ENV, EVAM vibration analysis, FFT with symptoms and Rotor balancing with Single plane balancing.
