Advantageous features of volume 1. Turn the rotary fan small fan, air volume, low noise, energy province (rotary blowers uses the principle of operation of compressed air, although the volume is small, but air volume, energy saving, quiet operation other forms of fan . incomparable 2. Anti load change, stable air volume (for example: wastewater treatment aeration tank pressure changes, the load change in the rotation fan, but the wind has changed little with the pressure change) 3. Turn the fan maintenance is simple, less failure swing. Fan use, long life (low-speed rotary turbine prices, wear small, long life) rotating fan performance testing methods: medium and small rotary fan performance testing research, make full use of the existing air-chamber outlet type rotary blower performance test device into the modern virtual instrument technology, through virtual instrument DAQ data acquisition module where the cheapest rotary blower, a set of PC-based machine rotary fan performance automatic acquisition system. The system can automatically collect rotary fan That original parameters dynamic pressure, static pressure, torque, speed, temperature, and calculate the corresponding flow, efficiency, shaft power, drawn pressure, efficiency and shaft power are dimensionless dimensionless curve with changes in flow, Print output curve and data reporting. rotary blower use, Kunming rotary fan, Zhucheng East Han Machinery Co., Ltd. by John Zhucheng East Machinery Co., Ltd. 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.
