Principle of operation of the rotary fan with compressed air, Shijiazhuang rotary fan, though small in size, but large air volume, energy saving, quiet fan operation is otherwise unmatched. Smooth operation, easy installation, minicomputer species as long as it is properly seated small vibration during operation, does not require the installation of anti-vibration device, easy to install. Rotary blower main base, fan host, motors, air chamber, drip nozzle and air filter components, the main purpose is to: sewage treatment, water pollution aeration stirring, rotating fan factory outlets, the printing industry vacuum feed, industrial waste stirring aeration, the glass industry, aquaculture and many other places, widely used. Methods for measuring performance rotary fan: the study of small rotary fan performance testing, full use of existing wind-chamber outlet type rotary fan performance test device into the modern virtual instrument technology, through virtual instrument DAQ data acquisition module, rotary blower where good, based on the establishment of a rotary fan performance automatic acquisition system PC machine. The system can automatically collect original parameters namely rotary fan dynamic pressure, static pressure, torque, speed, temperature, and calculate the corresponding flow, efficiency, shaft power, to map out changes in pressure, efficiency and shaft power with the flow of There are dimensional and dimensionless curves, curves printout and data reports.
