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 of the rotary fan outlets, the unit is kw. (2) Efficiency: Rotary fan input power can not all be transmitted to the conveying gas, wherein the portion of the energy loss must rotary blower, the gas is actually delivered the resulting ratio of the prime mover to the power transfer rotary power to the fan shaft a small Their ratio is called rotary fan efficiency. The higher efficiency of the fan rotating rotary blower use, the effective portion of the energy of the gas obtained from the rotating fan in the greater economy higher. Rotary blowers characteristics: small size, air volume, energy province, quiet operation; it is also known as: low noise blower; smooth, vibration-free, easy to install; wind pressure changes from impact loads, smooth air flow; fan lubricating oil filtration unit rotary blower manufacturers, wholesale, quality assurance cycle oil and oil smooth; air chamber design using advanced technology, both to ensure the separation of the effects of oil and gas, but also to prevent air pulsation, to ensure the smooth bulk gas; low speed, wear small, long life. Direct rotary blower, rotary blower, Zhucheng East Machinery Co., Ltd. is provided by John Han Machinery Co., Ltd. Zhucheng East. Zhucheng East Han Machinery Co., Ltd.
