Detailed description of the invention:
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
The Silence Process formula axial fan that this utility model produces with Chengdu Power Machinery Works as specific embodiment, stator blade
The blower fan signal of adjustable shaft streaming blower fan is AN, and following Silence Process formula axial fan is all referred to as AN blower fan.
Silence Process formula axial flow type fan impeller tool special for dismounting, including ring flange the 1, first bolt 5 and the second bolt
6, the outer ring of described ring flange 1 is provided with multiple outer ring bolt hole 2 being evenly distributed, the inner ring of described ring flange is provided with
Multiple inner ring bolts hole 3 being evenly distributed, the quantity of described first bolt 5 is equal with the quantity of described outer ring bolt hole 2；Described
The quantity of the second bolt 6 is equal with the quantity of described inner ring bolt hole 3；The size of described ring flange 1 and the half of AN draught fan impeller
Coupling size coincide, and described ring flange 1 inner radii is less than the radius of AN blower fan main shaft, and described first bolt 5 passes through flange
Half a coupler is fastened on impeller by the outer ring bolt hole 2 of dish 1, the described second bolt 6 inner ring bolt hole 3 by ring flange 1
Hold out against the end at AN blower fan main shaft.The quantity of the outer ring bolt hole 2 being evenly distributed on the outer ring of described ring flange 1 is equal to impeller
The quantity of the bolt hole on half a coupler.The position of the outer ring bolt hole 2 being evenly distributed on the outer ring of described ring flange 1 and impeller
Bolt hole on half a coupler is corresponding.The size of the outer ring bolt hole 2 being evenly distributed on the outer ring of described ring flange 1 and leaf
Bolt hole on wheel half a coupler is consistent.The quantity of the inner ring bolt hole 3 being evenly distributed on the inner ring of described ring flange 1 is 5.
Described ring flange 1 and bolt 5 all use stainless steel material to make.
This utility model be dismounting AN draught fan impeller specific purpose tool, AN blower fan by inlet box, size current collector, adjustable before
Stator assembling, casing assembling (impeller housing and rear guide vane assembly), rotating group (torsion pass jackshaft, shaft coupling, impeller, base bearing
Assembling), diffuser, the composition such as cold wind pipeline and lubricating pipe.During the work of AN blower fan, air-flow is entered inlet box by air channel, passes through
Convergence and pre-supination, air-flow is done work by impeller, and the screw of air-flow is converted into axially-movable again by rear guide vane, and at diffuser
Interior most of kinetic energy of gas is changed into the static energy needed for system, thus complete AN blower fan work process.
AN draught fan impeller is large fan core rotatable parts, and modern large-size thermal power plant mostly uses big flow, height
Parameter advanced version blower fan；Due to the big flow of AN blower fan, high parameter, the impeller diameter of AN blower fan is big, and 600MW unit impeller diameter reaches
4000mm.Because AN draught fan impeller diameter is big, the difficulty dismantling impeller during AN maintenance of fan increases accordingly.
According to AN blower fan structure, according to AN draught fan impeller half a coupler dimensioned this utility model.
Operation principle of the present utility model is:
The first bolt 5 in this utility model passes sequentially through outer ring bolt hole 2 and ring flange is installed on impeller 4 half a coupler
Place, half a coupler is fastened on impeller 4 by ring flange 1, makes the second bolt 6 pass sequentially through the inner ring bolt of ring flange 1 with spanner
Hole 3 holds out against the spindle nose at AN blower fan, and using spanner to fasten 5 the second bolts 6 successively just can easy removal AN draught fan impeller
4.Use this utility model remove AN draught fan impeller can effectively prevent use jack excessive cause screw rod fracture hurt sb.'s feelings and damage
Equipment, it is possible to an impeller difficult problem cannot be removed when avoiding because of jack pair large deviations；This utility model is used to remove AN draught fan impeller
Need not heating, can reduce impeller rigidity, strength failure in effect；This kind of method removes AN draught fan impeller to center without strictly wanting
Ask, only need people top fastening bolt in order just, can tube reducing intensity of workers.
Although detailed description of the invention of the present utility model is described by the above-mentioned accompanying drawing that combines, but not new to this practicality
The restriction of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
