Centrifugal wind chassis control parameters chosen for the whole pressure, air flow, noise, efficiency and motor power. Centrifugal wind chassis since the wind chassis, muffler favor. Centrifugal wind chassis selection, consider the leakage loss of the piping system, the principle of the calculation error centrifugal fan, and fan the actual wind, air pressure negative deviation centrifugal fan models, but do not use too much, in order to prevent long-term at a centrifugal fan running low efficiency centrifugal fan service area, note the relationship between the pipe network resistance characteristics match with the fan characteristics. After a new installation of centrifugal fans began formal operation, or the occurrence of excessive or too small flow during use, to eliminate one of the following ways: 1) the use of throttling device to regulate the flow. 2) change the fan speed to regulate the flow. 3) higher or lower exchange pressure blower adjust the flow. 4) Change the pipe network resistance coefficient adjust the flow. Centrifugal fan models _ liter Swiss mechanical and electrical (certified) _ centrifugal fan ventilation and air conditioning provided by the liter Swiss mechanical and electrical equipment factory. L Rui HVAC Electrical Equipment Factory (www.dzsrxfkt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In liters Swiss electromechanical leadership with the staff warmly welcome all inquiries negotiations to create liter Swiss electromechanical better future.
