CFZ-7Q8 bottom blowing anti-corrosion cooling transformer axial fan

CFZ-7Q8 bottom blowing anti-corrosion cooling transformer axial fanBased on the advantages of similar products at home and abroad, the impeller is designed and manufactured using high-efficiency and low-noise blade shapes. The impeller is made of high-quality anti rust aluminum sheet or composite wing shaped blades, and the supporting motor is a low-noise motor. The motor bearings are double sealed motor bearings. The shaft end is designed with a double set bearing structure, equipped with waterproof sealing, and has good protective performance. Its protection level reaches IP55, suitable for outdoor use. Therefore, this product has the characteristics of low noise, high efficiency, stable performance, reliable operation, and long service life.

Motor temperature rise: The motor adopts B-level insulation, the temperature rise limit of the stator winding (resistance method) is ≤ 45K, and the allowable temperature of the bearing (thermometer method) is ≤ 95 ℃; The bearing has a service life of 10 years under normal operating conditions and can withstand continuous operation under rated load. It can also ensure safe operation for no less than 5 years before * major repairs.

CFZ-7Q8 bottom blowing anti-corrosion cooling transformer axial fanIt is designed and manufactured according to the industry standards of the People's Republic of China, such as JB/T9545-2002 "Technical Conditions for Three phase Asynchronous Motors for Transformer Cooling Fans" and JB/T9642-1999 "Transformer Fans". It is mainly used for heat dissipation and cooling systems of large and medium-sized transformers, and can also be used for blowing and exhaust in other places. Its noise is reduced by an average of 3-10dB (A) compared to traditional products. DBF-5Q8 and DBF-5Q6 are available in two types: 4-blade and 3-blade. The technical specifications are as follows: impeller diameter: 500mm, synchronous speed: 1000r/min, air volume: 6500m3/h, full voltage: 120/140Pa, current: 1.33A, voltage: 380V, frequency: 50Hz, power: 0.37Kw, noise: 64/67Db, weight: 18kg. The DBF series transformer fan is suitable for cooling systems of large electronic transformers and electric furnace transformers. It is designed and manufactured according to the standards of the machinery industry of the People's Republic of China, such as JB/T9642-1999<<Transformer Fan>>. This product draws on the advantages of similar products at home and abroad, and has excellent aerodynamic performance, low noise, high efficiency, stable performance, reliable operation, long service life, high protection classification, safety and reliability. It is currently one of the lowest noise transformer fans in China. This series of products has been used in conjunction with nearly 20 large and medium-sized transformer factories, including Shenbian, Baobian, Xibian, etc. The DBF series transformer fan adopts low-noise blade type, willow joint blade type, riveted impeller. The motor is a low-noise motor, using imported low-noise bearings. The motor shaft extension end adopts a double set bearing structure, which has good protection effect. The motor housing protection level is IP55, suitable for outdoor use.
