1, the AC cooling fan is generally divided into two types of bearing.
A, oil bearing, the bearing parts have sealed space, inside sealing quality lubricating oil, oil bearing theoretical service life of 30000 hours, quality assurance for a year. Two, ball bearing, bearing the rolling precision bearing, a total of two. Theory of ball bearing service life 50000 hours, quality assurance two years.
2, AC series cooling fan blades have 5 blades and 7 two blades. 5 blade of fan, the characteristic is the wind speed is faster than the effect of air volume 7 leaves relatively than effect. But air dispersion, large range of wind. 7 blade of fan, characterized by wind pressure is big, wind focus. But 5 blade air volume is relatively small.
3, AC cooling fan voltage can be divided into three series. AC voltage 110 v, withstand voltage range of 80 ~ 120 v, the voltage is too large, easy to burn machine. AC voltage 220 v, the power range of 180 ~ 240 v, our country one of the most commonly used voltage, the range of the most widely used. AC voltage 380 v, the power range of 360 ~ 450 v.
4, waterproof type AC series cooling fan, conventional type, high temperature resistant type three kind of function classification. A regular pattern. Using temperature range is 10 to + 80 degrees Celsius, environment humidity less than 75%. Two, waterproof type. Using temperature range is 10 to + 80 degrees Celsius, environment humidity of 98%. 3, high temperature resistant type. Using the temperature range is - 30 to + 150 degrees c, environment humidity is 98%.
5, a series of AC cooling fan speed, air volume can be produced according to customer requirements. Of course in most cases are using the standard speed and air volume, if you have special requirements, we can also be customized according to the requirement.
6 and the series of AC cooling fan of the led source line connection mode has two kinds of light type and socket type. Light type, it is only two or three thread, thread without any decoration, need the fan by means solder welding to the equipment transmission; Take the plug socket type, thread himself, can be directly inserted into the device power socket
