Manufacturers Which Lianyungang fan fan before unpacking should check the packaging is intact, each comes with complete accessories are complete, the product is divided into single-speed and two-speed two models, according to different occasions, changing the mounting angle of the fan change leaf number and converting speed to its requirements. Fan performance parameters are mainly flow, pressure, power, efficiency and speed. Fans are used in various fields of national economy metallurgy, petrochemical, power, urban rail transport, textiles, shipbuilding, etc., and various places of ventilation. Fans effective power and shaft power ratio is called efficiency. Which fan factory Lianyungang addition, noise and size of the vibration is also a major fan design specifications. Also called air volume flow to flow through the fan indicates the volume of gas per unit of time; pressure, also known as pressure, refers to the value of the gas pressure rise in the fan, there is static, dynamic pressure and total pressure points; power is the fan input power, namely shaft power. In addition to traditional applications in coal gangue, more than 20 potential markets dry process clinker technological, metallurgical industry and other energy-saving and comprehensive utilization of resources will have greater prospects for development. Fan total pressure efficiency up to 90%. Check again before installation fans all parts are in good condition, otherwise it should be repaired after use; carefully read the instruction manual and sample fan, knowledge and understanding of the fan specifications, forms, and out of the impeller rotation direction and airflow direction.
