[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product --T30 / T35 axial fan] works when the impeller rotates, the gas from the inlet into the impeller HTF axial exhaust fan, by pushing on the impeller blades squeeze the gas by increased energy, and then flows into the guide vane. Vanes will deflect airflow into axial flow, while gas is introduced into the diffuser tube, and further the gas pressure is converted to kinetic energy, and finally introduced into the service line. Work axial fan blades similar to airplane wings. However, the role of which is to lift up on the wing and supports the weight of the aircraft, while the axial fan is fixed position and air movement. Cross-sectional axial fan is generally airfoil. Blades may be fixed position, and to be rotating about its longitudinal axis. Blades and the blade pitch angle or the air flow may be adjustable or not adjustable. Changing the blade angle or pitch is one of the main advantages of axial fan. Small blade pitch angles produce lower flow rate, while increasing the spacing may produce a higher flow rate. Advanced axial fan blade pitch can be changed when the fan is running (which is quite similar to a helicopter rotor) non-powered fan, thus changing the flow rate accordingly. This is called variable pitch (VP) axial fans. [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 spray, brush and other fans crossing technology, but have certain drawbacks: high temperature welding thermal stress generated can not be completely eliminated, could easily lead to material damage, resulting in part appears bent or break; and electric brush by coating thickness limit, centrifugal fan off easily, and the above two methods are used to repair metal metal, can not change the "hard on hard" relationship with the fans at the combined effects of various forces, still Wear plastic bag causing the drum 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 compressive strength and other comprehensive performance, free-free disassembly machine processing. 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.
