Most of ternary flow impeller, centrifugal fans later, can be increased by 5% to 10% efficiency of the fan at the same flow rate and pressure conditions; good after the new fan design, in order to verify the effect of its design, the need to create a model of the fan test, if not reach the expected efficiency goals, but also to make design modifications, re-test, Shijiazhuang centrifugal fan, until satisfaction; after the popularity of computer technology, the emergence of computational fluid dynamics simulation study that is simply recalculated You can assess the effectiveness of improved design. Although it needs a performance test, centrifugal fans specifications, it is the performance in order to further validate the design of the product. In order to design more energy-efficient centrifugal blower cabinet. Fans appear abnormal sound during operation, the motor severe fever, live shell, switch trip and can not start other phenomena, should immediately stop checking. To ensure safety, do not allow for maintenance of the fan running. After commissioning inspection should be carried out for about 5 minutes, centrifugal fan price, confirmed that no anomalies start running again. 4, the fan should be stored in a dry environment, avoiding motor damp. Fans at open storage, measures should be rain. During storage and transport process should prevent the fan bump, so as not to damage the fan. Centrifugal fan applications, up Swiss mechanical and electrical (certified), Shijiazhuang 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.
