AIR COOLER FAN PROFILE
Within the device, fan is electric driven air configuration leaves after electrify after turning into the effect of natural wind to get cold, there are two types, axial flow fan, dc fan.
AIR COOLER FAN CONSTRUCTION
Rotor: magnets, blades, shaft
Stator：Silicon steel sheet, coil, bearing
Control system;By induction magnet IC, n. s. pole through the conduction coil circuit control its internal excitation rotor rotation.
AIR COOLER FAN WORKING PRINCIPLE
Working principle :Electric coil in the magnetic field force and rotation.
Energy conversion form:Power which is converted into mechanical energy, and at the same time because of the coil resistance, so inevitably there is part of the electrical energy into heat.
HOW DOES THE AIR COOLER FAN WORK
Series fan, wind pressure increases, but the air is changeless, using near wind resistance is too big, and guarantee the air volume
Parallel fan, wind pressure constant, air volume, heat dissipation effect increased
AIR COOLER FAN NOTICE
①System impedance:The air flow resistance will cause air flow noise generated
②Voltage fluctuation,Voltage fluctuation will cause the fan speed change, make work unstable and generates additional noise.
③fan speed and size,with the more fester speed and size,the cooling effect is more better. But the noise will becomes lager with the bigger fan size.
④Vibration,The vibration is the reason of increasing the fan’s noise and Reduced life spans and lower speed
⑤Air turbulence,Port of bad design can cause air turbulent flow in high frequency noise
AIR COOLER FAN TYPES
1.FAN TYPE,Axial fan, Centrifugal fan, cross flow fan
2.Purpose,home air cooler fans, industry air cooler fans
①Home fans ,type,Ceiling fan, floor fan, wall fan, roof fan, exhaust fan, pp fan, air cooler fan
②Industry fans,It is mainly used for forced air convection .
3.Motor construction ,single-phase capacitance,single phase mask pole,Three phase induction
HOW TO SELECT AIR COOLER FAN
Features of desktop and floor type with simple construction and operation as well as reasonable price.But only with speed and air direction functions.
Features of desktop and floor type with several functions and can be controlled as well as smart appearance.
tip of selections
①If has the certificates. To remind consumers to buy electric fans, whi want to see clear instructions and look to whether have compulsory certification of quality system certification, inspection standards certification, at the same time, pay attention to whether reached national standards of energy efficiency.
②Noise . Noise from motor , when you select the air cooler fans, consumers need to pay attention to the motor running if with noise and vibration and stable. Good motor with low noise.
③Security . Qualified fan, adult's finger can't touch the blade leading edge by net,.Families with children should choose more net of electric fan to prevent children because of curiosity and put your finger in, in order to avoid unnecessary damage.
④Odor. Smell is on the electric fan copper the smell of the insulating varnish coating during operation.During the process of selection, catching on the factors of environment friendly and the quality testing report .
AIR COOLER FAN MAINTENANCE AND SECURITY
1.Must use the protective earth three core plug and socket
2.During the fan installation, disassembly ,cleaning or using, must pay attention to protect.
3.Can’t press the two button at the same time and too powerful,
4.Please clean the dust and oil in time, don’t clean it by gas or strong alkali liquor to wipe to injure the parts function.
5.Don’t use it again when the product with high temperature and smelly as well as speed slow.
6.When not in use, thoroughly remove oil and dust on the surface of the first, use dry soft cloth to wipe clean, clean cloth with kraft paper or to wrap, location should be dry and ventilated, avoid extrusion.
Air cooler collection and preservation
1.Correct disassembly parts: correct disassembly parts according to electric fan line drawings requirements, operation is to open the first net clamp, screw fastening bolts on wind leaf sleeve, remove the blades; Unscrewed the fixed net after four screw nut, remove the gasket and the net, after will nuts washers.
2.Maintenance: plating with a soft cloth will first plating pieces of the stains and water vapor to wipe clean the dust, and then coated with a thin layer of engine oil, for protection. (note: must be wiped clean before oiling, otherwise the oil moisture not easily after evaporation and dust may cause corrosion, instead cause plating a rust.
3.Paint a maintenance: wipe with a soft cloth, if the stain is not easy to erase, available contain less alkaline soap water scrubbing, or with a small amount of kerosene wiping, then clean and dry. After removal of blades with a soft paper, on the net between before and after, lest the wind leaf Angle deformation.
4.Other parts of the maintenance: the power cord can't contact harmful gases, such as the mosquito-repellent incense, gas, etc., or you will change the color or even an accident. Motor bearing is oil bearing brass, for its not oil, can inject a moderate amount of oil in the oil hole. Shake head a knob on the head position in the beginning, in order to avoid pressure spring in the compression state. 5. Before the fan head into the plastic bags and carton, best no-load running more than ten minutes, until the fan head cool completely before packing, so can make the motor in the dry state during winter.
