Abstract
The invention discloses a nuclear centrifugal fan which comprises a casing, an air inlet, an impeller, a casing seal, a spindle, a belt, a belt pulley, a bearing, a bearing seat, a matching motor and an integral support. The lateral wall of the casing is in a flange structure, and a groined reinforcing rib plate is arranged on the casing. Compared with the prior art, the nuclear centrifugal fan has the advantages that the strength and the rigidity of the fan are enhanced, the integral performance of the fan is improved, vibration of a unit is decreased, the sealing performance is improved, the unit is not easy to fail, and the service life is prolonged greatly.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of blower fan, particularly a kind of blower fan that is applied to nuclear power generating sets air draft and air flow.
Background technique
Blower fan mainly is used for air draft and air flow in nuclear power plant; Usually form by parts such as motor, casing, impeller, main shaft, bearing, intake grills; General blower fan is owing to considering cost performance, and is all very traditional on the design and fabrication of each parts, as long as satisfy certain standard; Be not very long the working life that makes blower fan like this, and exist vibration big, leak shortcoming big, poor stability.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of existing technology, provide a kind of vibrate little, leak less, the nuclear level centrifugal blower in the safe nuclear power field that is applied to.
Technological scheme: nuclear level centrifugal blower of the present invention its objective is such realization: a kind of nuclear level centrifugal blower comprises casing, intake grill, impeller, casing sealing, main shaft, belt and belt pulley, bearing and bearing support, necessary electromotor, integral support; The body supports position of blower fan is a casing, and intake grill is connected with casing with bolt at the flange place, and bearing support is put on the bearing bracket; And use bolton, through the locating stud location, main shaft passes through bearing fixing on bearing support; The bearing end is provided with adapter sleeve; Impeller is passed and is fixed on by main shaft on the main shaft, and casing sealing is set on the casing, and main shaft passes casing sealing; Belt pulley be fixed on main shaft one end, necessary electromotor through belt link to each other with blower fan main shaft, the whole integral support that is provided with of blower fan.
The sidewall of said casing is made into turnup structure, flange square up structure or trough rim structure, the flange of these two kinds of forms; Intensity is high, resistance to shock is good, has increased the blower fan integrity, reduces fan vibration; And on casing, arrange " well " word reinforcement gusset, increase casing rigidity.
Said casing thickness increases to 6.0-10.0mm by original 2.5mm, strengthens the bulk strength and the rigidity of housing.
Said impeller material is selected low alloy steel Q345 for use, increases the Security of impeller.
Said casing sealing adopts novel ceramic fibre material, and self lubricity and good seal performance can effectively be resistance to worn, leak few.
As optimization: the model of said bearing and adapter sleeve is 22313EK and H2312, increases the global reliability ability of blower fan.
As optimization: said bearing support model is SNL516-613, increases the global reliability ability of blower fan.
Beneficial effect: nuclear level centrifugal blower of the present invention compared with prior art, has increased the strength and stiffness of blower fan; The blower fan overall performance is improved, reduced the vibration of unit, and sealability improves; Unit is easy fault not, and increase working life greatly.
