Q:What is the principle of a vaneless fan?
The base there is a similar air compressor device, the air is sucked in, after compressed by spraying out annular gap above the ejected air annular air flow driven device, has the wind.
Q:What are the advantages and disadvantages of the vaneless fan?
Non - leaf noise makes it necessary to absorb air at the base
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:Why does the fan seem to spin backwards when it spins?
This is the reason that the wheel looks stationary, when the frequency of the fan's rotation is related to the maximum frequency that the human eye can tell.
Q:Fans can shake their heads, but fan leaves do not turn, where is the reason?
The motor is short of oil, jammed or covered with hair
Q:How is the fan made up?
The fan is mainly composed of fan head, fan blade, net cover and control device. The fan head comprises an electric motor, a front and rear end covers and a head blowing air supply mechanism.
Q:Why do most fans only have 3 blades?
The fan family use is generally 3 blades, the blade shape is a bird type (design terminology), this form of blade flow, low noise, in accordance with the principle of fluid mechanics, the three leaf has a good dynamic balance, not easy to produce oscillations, thereby reducing the abrasion of the bearings. Extend the service life and reduce the maintenance cost.
Q:How do you use an electric fan to set up an air distribution system in an air tight room?
In the absence of outdoor airflow, the warm air is lighter than the cold air. From a hydrostatic point of view, the temperature difference brings air stratification in the vertical direction
Q:What are the common faults of electric fans?
In case of abrasion, the blade does not rotate. The easiest part is to replace the parts, especially the shaft sleeve, which is easy to burn if worn.
Q:What is the difference between air conditioner speed regulation and electric fan speed regulation?
The difference between them is reflected in the range of speed regulation with a fixed torque load. Two, the motor efficiency is reflected at different speeds. Three, the torque is expressed at different speeds.
