Variable frequency motor 30 kilowatts G200 Frequency Inverter Motor Fan Overview G series cooling fan (hereinafter referred to as G series fan), it is based on national standards "with the G series inverter motor cooling fans technical specifications" GB Standard / T 22712-2008 Production Cheap products, mainly for cooling the drive power inverter dedicated YVF2 series three-phase asynchronous motors. With the promotion of application of frequency control technology continues to expand, various types of motor application of variable frequency technology is also increasing. Supporting its cooling fan also proposed a variety of different requirements. Our company developed and manufactured by G series fans, not only in accordance with international production standards type fan, but also according to the requirements of design and production of the household variety of different sizes, different uses cooling fans. Its fan motor through continuous improvement, improve production technology, product quality is getting improved, with wide application range for long life. Users in the purchase of G series fans can make their own drawings and other applicable requirements or provide, I will provide specially designed user manufacturing. Structure Description G series cooling fan from the fan cover, fan motor, fan, cage and other components, standard hood from sheet stretch forming by hydraulic machines, lengthened hood welded steel plate coil. Air inlet holes using 8 × 8 components. Fan motor with special design approach, protection class IP55. Fans of the series has a simple installation, low noise, vibration small, reliable operation. G series of fans for the voltage and frequency rated frequency can be 50Hz, 60Hz rated voltage single phase 110V, 220V, 380V and other three-phase 110V, 220V, 380V, 415V, 660V, 1140V and other applicable environmental conditions, no more than 1000 meters above sea level. An ambient temperature of -15 ℃ ~ + 40 ℃. Relative humidity ≤90%. Work S1. Protection class IP54 or IP55. Maintenance should be connected to a separate power supply fan, you can not use the power inverter. After energizing the fan should check whether the rotation direction of the steering is consistent with the identification. Fans packed in cartons during transport should be handled with care, to avoid the collision and percussion, acid and other corrosive substances is strictly prohibited and transportation together. Fans should be stored at an ambient temperature of -10 ℃ ~ + 35 ℃, relative humidity ≤70%, a clean and well-ventilated warehouse, the air should not contain corrosive gases. Warranty the user to properly use and store the fan case, from the date of less than one year, due to poor manufacturing quality wind turbine itself damage occurred or not functioning, free of charge for users to replace or repair, damage caused by improper use The factory is not responsible.
