This equipment is with good flexible capacity and expandable capacity, it can supply a series of air flow system related experiment and research.
Part I: dynamic part, it supply enough wind energy to experiment, through inverter speed adjustment button to change fan rotary speed, so as to change equipment wind speed.
1. When experiment, turn on power supply protection, at this time, power signal indicator turn on, means equipment is with electricity(or equipment had powered on).
2. Press start button, fan start to work, according to real requirement, to adjust inverter speed adjustment button, adjust fan rotary speed, change wind, so as to change experiment required wind.
Part II: experiment part, through changing test module, to do different wind experiment.
1. Use connecting tube to connect fan and air chamber, air chamber function is to adjust wind direction, it is buffer room.
2. When do experiment, air chamber must be seal, air chamber cobber is fastened through screw, to realize seal in chamber.
3. When do experiment, connect module with air chamber though bolt, to avoid leakage air.
