Rotary fan workflow is: intake stroke, compression stroke, exhaust stroke of three parts. When the fan is rotated, so that the four vane rotor slot reciprocate rotating fan Which is good, the air is sucked into the compression discharge. Rotary fan characteristics 1, anti load changes, air flow and stability. 2, with the air chamber where a rotary blower, smooth diffuser. All models with air chambers, to prevent air pulsation, smooth diffuser. 3, material well rotary fan factory direct, clever structure, performance excellence. Blowers all high-quality materials, compact structure, durable Changsha rotary fan, high performance, long-term use of a small fault. 4, maintenance simple. Low speed, wear, long life. Rotating fan's role. Eccentric loading when the rotor rotates in the cylinder body. The turning turbine rotor blade slot 4 reciprocate. The air is sucked into the compression discharge. Constitutes fan blades and rotor, the cylinder block mutual friction generates heat. So the fan operation, the drip mouth dropped to the cylinder block necessary lubricants, lubricating surface to reduce friction heat and friction noise; and part is formed between the layer of film fans to keep rotating seal. Circulation means pressure lubrication system is generated when the fan is working via the rotary formed by the difference of the automatic supply of oil, and therefore can not be empty load operation rotary fan! The role of the host head of the role of the rotation of the rotary blower fan use is self-evident that it is a vital part of the rotary fan. Where rotary fan is good, Changsha rotary fan, Zhucheng East Machinery Co., Ltd. by John Han Machinery Co., Ltd. Zhucheng East. Zhucheng East Han Machinery Co., Ltd. (www.dhlcfj.com) (www.dhlcfj.com) strong, credible, Shandong Weifang fan, ventilation equipment industry has accumulated a large number of loyal customers.
