Waterproof fan waterproof rating

　　Electronic measuring instruments waterproof rating reflects the ability of the instrument waterproof and moisture-proof fan fan, especially for outdoor activities, inevitably in high humidity or dust in harsh environments, waterproof seal and waterproof fan for safety and security equipment operation and life is crucial. For this purpose: to develop international standards IEC529, in order to adapt to this, the Japanese standard in the process of protecting electronic equipment is divided into 10 levels, respectively IPX1, IPX2 ...... .. representation

　　Working life: Ambient temperature -40 to + 60 ° 30,000 hours, the built-sensitive temperature sensor, enabling the number of revolutions varies with temperature and current, so that the cooling effect to achieve the best results. Vacuum coating applications where it is completely waterproof fan can operate in water, is a suitable under water at high humidity and even harsh environments, solve the outdoor water point humid heat problems.

　　Main work to solve: the heat problem IP field, sports equipment, welding, power systems, medical equipment, instruments, machinery, racks, chassis, power supply, electrical appliances, communications equipment, computers, automatic control, ventilation and cooling systems, and other industries

　　Mainly used for cooling fan protective role, affecting the normal operation to prevent foreign matter from entering the fan, and also to prevent careless hands hurt.

　　Waterproof Fan Description: Our knowledge has made China Patent Office issued a patent certificate IP55-IP68 waterproofing technology, experimental purposes: to verify 5% salt spray test the fan through the fan at the rated voltage of 12V placed in 5% salt spray test machine, let the fan continues to run for six months, and will not be able to operate normally burn in 50 centimeters of water. Waterproof fan

　　Define the degree of protection

　　0 No protection No special protection

　　1 prevents objects larger than the 50mm prevent human intrusion inadvertently encountered inside the lamp body parts to prevent the intrusion of a diameter greater than 50mm

　　2 to prevent objects larger than 12mm to prevent the intrusion of a finger touch the internal parts of the lamp

　　3 to prevent the whole thing greater than 2.5mm diameter greater than 2.5mm invasive tool to prevent the wires or objects intrusion

　　4 to prevent the intrusion of an object larger than the 1.0mm diameter greater than 1.0 to prevent mosquitoes, insects or objects intrusion

　　5 dust can not completely prevent dust intrusion, but does not affect the amount of dust invade the normal operation of the lamp

　　6 dust completely prevent dust intrusion

　　Waterproof grade numbers define the degree of protection

　　0 No protection No special protection

　　1 prevents water droplets dripping prevent intrusion of vertical drop

　　When the two are still tilted 15 degrees to prevent the intrusion of water dripping when the lamp tilted 15 degrees, you can still prevent dripping

　　3 to prevent the intrusion of water injection to prevent rain, or vertical angle of less than 50 degrees into the direction of the jet of water

　　4 to prevent splashing of water splashing from all directions to prevent intrusion of water intrusion

　　5 to prevent the intrusion of water to prevent the waves big waves or blowhole rapidly ejected water intrusion

　　6 to prevent the intrusion of big waves of water intrusion lamps water at a certain time or pressure conditions, still ensure the normal operation of the lamp

　　7 to prevent the intrusion of water ingress of water fixtures indefinitely sinking water at a certain pressure conditions, and to ensure the normal operation of the lamp

　　8 to prevent sinking

　　Working life: ambient temperature of 25 degrees 80,000 hours built-sensitive temperature sensor, the temperature change can be achieved with the number of revolutions and current, so that the cooling effect to achieve optimal results.

　　2. A waterproof cooling fan, comprising a rotor, a stator and a fan frame; the motor rotor includes a fixed shell and the inner wall of the ring-shaped permanent magnet fixed to the motor housing radially outer wall of the fan ring, and fixed blades an axial end surface of the center ring extending inwardly rotor shaft fixed to the rotor shaft and two bearing; a stator comprising stator laminations and the upper and lower insulating base, and the stator windings and the electrical winding thereon the stator winding connection the printed circuit board; after the stator is assembled into a mold, with a hollow plastic injection molded cylindrical seal whole, the printed circuit board electrically connected to the two input leads from the feed line the entire inner seal; the the overall seal stator into the fan frame, the frame outside the bearing sleeve at the bottom of the outer frame of the fan, and then fixed to the two bearing rotor shaft and the stator of the center space, so that the two bearing at the bottom of the fan frame of the stand within the framework of a fixed bearing, which can be powered cooling fan running for. The utility model is waterproof type cooling fan with low cost, good waterproof effect, etc. Waterproof fan
