The main performance parameters of rotary fan there is traffic, total pressure, power, speed and efficiency. (L) flow rate: the amount of fluid per unit of time delivered by the rotary fan is called flow. Common volume flow Q, said its unit is "resistant / s" or "m 3 / h". Strictly speaking, where the best rotary blower, rotary blower flow, especially rotary blower inlet volume flow. (2) total pressure: energy per unit volume of gas in the rotary fan obtained called full pressure or pressure to the fan rotation P represents the price unit is Pa. (3) shaft power: the power delivered to the prime mover rotary rotary blower fan on the shaft, is the input power rotary blower outlets, also known as shaft power, expressed in units of p kw. The main performance parameters of rotary fan there is traffic, total pressure, power, speed and efficiency. (1) Effective power: the total energy per unit time through a rotary fan gas obtained is called the effective power units kw. (2) Efficiency: Rotary fan input power can not all be transported to pass gas, which must be part of the energy loss, the gas is transported to obtain the actual power transfer than the original motivation to rotary fan shaft power to be small, they The ratio is called rotary fan efficiency. The higher the rotary fan efficiency, the effective portion of the energy is derived from the rotary gas blower in the greater economy higher. Rotary blower use, Zhucheng East Han Machinery Co., Ltd. (certified), rotary blower provided by Zhucheng East Han Machinery Co. Zhucheng East Han Machinery Co., Ltd. (www.dhlcfj.com) is an industry leader in Shandong Weifang, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Zhucheng East Han Machinery Co. led the staff warmly welcome all inquiries negotiations to create Zhucheng East Han Machinery Co., a better future.
