Anonymous users2024-01-23The three-phase axial fan changes from exhaust to supply, and as long as any two of the phase wires are replaced, the steering is reversed. To reverse the rotation of the single-phase fan, as long as a wire connected to the capacitor is changed from one end of the original capacitor to the other end of the capacitor, the single-phase motor will be reversed. But the change poses two problems:
First, the fan blades and motors. 3195
Check whether the capacitors of your power supply and the power supply close to each other have exploded, the capacitors are standing vertically on the board one by one, and the explosion means that the top is flat and has become a little protruding, and the protrusion is bursting, and the capacitor can continue to be used but is unstable.
There are many possibilities for loud noise, one is the check valve, the other is that the smoke pipe is too long and the internal pressure is too large, and there is the loose fan blade and the bending of the bearing, I don't know which one you belong to?
Depending on the quality brand, there are 30 to 150. Hope it helps. >>>More
Many small restaurants and some old houses use exhaust fans. The effect can only be said to be average, after all, the location will not be on the top of the stove like the range hood, the principle of the range hood is the same as the exhaust fan, and the oil can be removed after a period of time. >>>More
Just switch the power cord of the capacitor from one end of the capacitor to the other. Or install a SPDT switch (which you can find at a hardware store) and you can easily change the steering of the ventilator. The wiring diagram is as follows:
