DESCRIPTION
The basic testing principle is to simulate the actual working state of the test specimen in the testing wind tunnelChange the diameter of the orifice plate of the air outletThen measure itEach static pressure value of the air outletCalculate the corresponding value at this time using the standard formulaofflow coefficientAnd parameters such as air volume.
This device adopts computer automatic measurement and control method, which only requires manual installation and replacement of test samplesorifice plateThe entire process of testing a sample only takes ten minutes. It can measure the corresponding curves of static pressure and air volume, air volume and speed, current, power, efficiency, etc. It has the characteristics of convenience, speed, stability, reliability, and good reproducibility. Satisfy the testing and use of related products in scientific research and production processes.
