Q:What is the principle of a vaneless fan?
The base will be a large amount of air from the suction hole at the bottom of the 5.28 gallons per second flow inhalation, then the air is pressurized into the annular inner wall, an impeller inside the edge of the ring in the air circular trajectory jet, change the air flow will cause the air pressure, and ultimately the formation of a cold air flow shares uninterrupted
Q:How to measure the quality of fan motors with digital multimeter?
In the multimeter stalls placed in the 20M file, measuring winding (using the motor three lines in any one) and the motor stator core insulation resistance, the resistance should be above 2M, can determine the motor only problem
Q:Is the power consumption the same when the fan is used in different gears?
High speed gears consume more energy, but high efficiency because of large output power. Low energy consumption is slightly lower, but the efficiency is low and the heat production is serious.
Q:When did the electric fan start to appear?
In 1883, the factory began mass production of this type of desktop fan.
Q:What is the function of the fan blade?
Five can lookout "cut" more small, quiet is better. Because of the "cut" the wind is more uniform, with five fans not only brought the silencing effect from the comfort of view is also much more choice, fan blowing can achieve a wider range than block adjustment
Q:What is the working principle of an electric fan?
The main components of the electric fan are: AC motor. The working principle is that the energized coil rotates under the force of the magnetic field. Electrical energy is converted to mechanical energy, and, at the same time, due to coil resistance, it is inevitable that some of the electrical energy is converted into heat energy.
Q:Does the fan blow the door open or closed?
Conditional doors should be opened against the door to form an air duct for the air convection.
Q:Why can an electric fan choose only 123 winds, and this discrete value instead of zero to three continuous type?
A multi throw switch is cheaper than a rheostat
Q:Have you been driving the fan, more electricity or more air conditioning?
If you want to use a fan, then put a basin of cold water on the ground in front of the fan in the room, and the cooling effect will be better.
Q:Why not head fan to blow?
The blower is suitable for choosing the head. If the fan blows directly to the head and neck, the scalp temperature drops, the reflex causes the contraction of the cerebral blood vessels, and the brain blood flow also decreases. For the elderly with cardiovascular and cerebrovascular diseases, severe stroke can be induced
