[Purification Equipment Co., Ltd., Tianjin Jinzhong Ji HVAC recommend to you the star product --4-72 centrifugal fan centrifugal fan] fault repair transmission parts wear is often seen equipment problems, including the blower bearings bit worn bearing chamber, blower shaft Bearing bit wear. Centrifugal fan for the failure of traditional repair methods are welding, thermal spraying, brush crossing, etc., but have certain drawbacks: high temperature welding thermal stress generated can not be completely eliminated, easy to cause material damage to the fan, resulting in part appears to bend or break ; The electric brush by coating thickness limit, centrifugal fan off easily, and the above two methods are used to repair metal metal fan technology, you can not change the "hard on hard" with the relationship, under the combined effect of the various forces boiler fans, still cause wear plastic bag roll again. To solve the above problems of contemporary Western countries use more polymer composites repair methods, and the application of more American blessing blue world technology system, which has superior adhesion, excellent strength and other comprehensive performance exhaust fan fire, may Removing free-free machining. Neither welding thermal stress on the repair thickness is not limited, while products with metallic materials do not have a concession, can absorb impact shock device, to avoid the possibility of re-wear at home against the centrifugal fan troubleshooting applications also gradually replace the traditional methods. [Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - Fan Fan performance parameters] main flow, pressure, power, efficiency and speed. In addition, the noise and vibration of the size of the fan is the main technical indicators. Also known as the air volume flow in the unit of time, said the volume of gas flowing through the fan; pressure, also known as pressure refers to the value of the gas pressure rise in the fan, there is static pressure, dynamic pressure and total pressure points; power is refers to the fan input power, namely shaft power. Effective power and fan shaft power ratio referred efficiency. Fan total pressure efficiency of up to 90%. Wind turbine technology, Tianjin Jinzhong Ji ventilation engineering (certified), provided by the Tianjin Tianjin Jinzhong Ji HVAC blower purification equipment.
