The invention relates to a system for comprehensive performance testing of a fan filter unit in the technical field of mechanical and electrical equipment performance testing, comprising: a computer; a surface wind speed measurement component with a plenum box capable of accommodating a tested FFU; an anechoic laboratory for Accommodate the static pressure box body and face velocity measurement components; fan components controlled by computer; air volume measurement components controlled by computer; Among them, the fan parts and the air volume measurement parts are arranged in the position outside the anechoic laboratory of the induced air pipeline in sequence according to the direction of the air flow, and the air inlet end of the fan part is connected to the outside atmosphere; the surface wind speed measurement parts include thermal anemometer, The detection ends of the acoustic measuring instrument, the thermal anemometer, and the acoustic measuring instrument are all facing the air outlet of the tested FFU. It solves the problem that the acoustic test and aerodynamic performance test in the anechoic laboratory cannot be combined; completes the test of all performance parameters of the tested FFU with a high degree of automation.
Description
technical field [0001] The invention relates to the technical field of performance testing of electromechanical equipment, in particular to a system for comprehensive performance testing of fan filter units. Background technique [0002] Fan filter unit (FFU) is widely used in clean laboratories and industrial plants with high cleanliness requirements because of its compact structure, remarkable energy saving, system negative pressure sealing, independent and flexible structure, and easy adjustment. In recent years, with the continuous miniaturization, integration, and precision development trend of electronic information products, the demand for FFU in electronic workshops has shown explosive growth, and the performance test of FFU has become particularly important. [0003] The FFU vertical installation reference device given in IEST-RP-CC036.1 "Fan Filter Unit Test" of the Pollution Control Branch of the American Society for Environmental Science and Technology, this devi...
