Exhaust fan Now it has been widely applied. How much do you know about the ultra high performance of the fan? How should we measure the wind pressure of the exhaust fan?
First, the test method of the full pressure pipe. In order to accurately measure the total pressure, it is necessary to accurately link the joints of the total pressure pipe of the product with the differential pressure gauge or positive pressure sensor of the comprehensive tester for the product according to the relevant provisions of the product instruction manual.
Second, Exhaust fan Pitot tube method. The wind pressure inspection of this equipment can also be started from two aspects. On the one hand, people choose the right pressure measuring section and install the pitot tube correctly. On the other hand, it is necessary to use a clean, unobstructed and airtight hose to connect the "+" (full pressure hole) of the whole pitot tube and the "-" (static pressure hole) joint with the pressure differential sensor "+", "-" (static pressure hole) or the pressure differential gauge "+" (full pressure hole) of the fan comprehensive testing instrument, respectively, so as to ensure the correct measurement. Full pressure and static pressure.
