Summary of the invention
The object of this invention is to provide and a kind ofly can solve the faults such as the SS7C type electric locomotive silicon blower fan unit axial flow silicon fan bearing heating scaling loss, the electromechanical shock vibration that run in China railways system are large, impeller deformed damaged comprehensively, the draught fan impeller for the heat radiation of electric locomotive silicon of the reliability of locomotive complete machine ride quality and traffic safety can be improved simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: it is made up of assemblings such as impeller boss 1, fan blade 2 and impeller flanges 3.
Impeller boss 1 of the present invention adopts the thick high strength Al-Mn serial alloy welding of 5mm to connect machine shaping.
Fan blade 2 of the present invention adopts 5mm thick high strength Al-Mn system alloy, and mould is colded pressing compressing.
Impeller flange 3 of the present invention adopts 8mm thick high strength Al-Mn system alloy, and impeller flange 3 is provided with the screw of more than 2 for fixing.
Of the present invention three large assemblies, its material is all adopted as Al-Mn system alloy, such as 3A21 aluminium sheet in Al-Mn system alloy, and 3A21 aluminium sheet is most widely used a kind of rustproof aluminum alloy, and the normal Cold-forming process that adopts improves its mechanical property; Have high plasticity in an annealed state, when half flow harden, plasticity is fair, and during flow harden, plasticity is low, and corrosion resistance is good, and weldability is good.The alloying element of A21 is manganese, and have splendid formed machining characteristic, highly corrosion resistant, good weldability and electric conductivity, intensity is higher.Domestic 3000 series of aluminium board production technology relative maturity, comparatively outstanding.
SS7C type electric locomotive silicon draught fan impeller assembling of the present invention: adopt specific welding assambly location, successively assembled welding carried out to impeller flange, impeller boss, fan blade by professional welding operation personnel in strict accordance with welding procedure; Strict machine shaping by drawing after welding, and carry out the detection of test group dress
The invention has the beneficial effects as follows: this design proposal keeps original installing space structure constant, reach easy and simple to handle, performance boost, application safety be reliable and stable.It is by the corresponding special construction of design, steel part structure, quality weight is adopted with the impeller solving former silicon blower fan unit, locomotive is in long-time continuous running state simultaneously, therefore the faults such as bearing heating scaling loss, electromechanical shock are vibrated greatly, impeller deformed damaged are often caused because of overload operation, locomotive silicon cell is caused to dispel the heat can not meeting expection to require and railway locomotive cannot normal reliable operation troubles, effectively guarantee the continual and steady reliability of its SS7C type electric locomotive silicon blower fan unit axial flow silicon fan operation, meet the safe and reliable Operational requirements of railway locomotive.It is mainly used for the fields such as electric locomotive silicon blower fan unit axial flow silicon blower fan.
