Description
Technical field
The present invention relates to vehicle ventilator design field.
Background technology
The features such as it is big that Modern High-Speed locomotive generally has power, axle heavy and light.General express locomotive shaft power is more than 1200kW,
Axle is heavily less than 20t.Locomotive is big due to single-machine capacity, and car body strength is high, and the weight therefore alleviating in-vehicle device is exactly high speed machine
One emphasis of car design, in in-vehicle device, the weight of ventilation blower accounts for the ratio that whole locomotive weight is bigger.Again due to high speed machine
The caloric values such as axletree power is big, current transformer in locomotive electric cad system equipment, transformator are high, are required to the propeller fan of big flow to it
Carry out forced ventilation cooling.Therefore develop a light-weighted ventilation blower of big flow be express locomotive design key content it
One.
Prior art one:
In railway systems, lightweight propeller fan is mainly used in EMUs, mainly changes the material of blower fan
Enter, such as, the casing of blower motor is replaced by cast aluminium material by cast iron quality, Blower Housing is replaced by aluminum by carbon steel material
Alloy material.But have a disadvantage in that, in EMUs, the universal flow of lightweight blower fan of application is less, casing, motor, impeller etc.
The intensity of critical component relatively easily ensures.But the needs of high-power cooling channel can not be met.
Prior art two:
In existing railway systems, the ventilation blower blower fan of the big flow of the lightweight of locomotive is relatively fewer, currently mainly pooled applications
Important asking in higher export locomotive countershaft, the casing of fan motor is replaced by by these ventilation blowers equally by cast iron quality
Cast aluminium material, is replaced by aluminum alloy material by Blower Housing by carbon steel material.
The propeller fan of existing locomotive is mainly by air duct (air duct is inner core and urceolus), impeller, and motor composition.As
Fig. 1.The flow of propeller fan is mainly by the rotating speed of impeller, leaf, and length of blade determines, wheel speed is by motor and power supply electricity
Source determine, ordinary circumstance railway locomotive fan power is 50Hz, and rotating speed is up to 3000 turns, leaf be optimized to a certain degree after nothing
Method improves flow performance, length of blade=1/2 (impeller diameter-hub diameter) again.That is when impeller diameter determines, wheel
Hub more vanelets length is the longest, and the flow of blower fan is the biggest.General axis flow blow hub ratio (hub ratio=hub diameter/impeller
Diameter) preferable flow can be obtained between 0.35-0.45.But the hub ratio major part of railway locomotive propeller fan at present
Between 0.5-0.6.Because the hub diameter of impeller typically cannot be less than the diameter of air duct in blower fan.Owing to motor is arranged on wind
In machine inside air duct, owing in electric machine structure size limitation blower fan, air duct diameter cannot reduce again, so railway locomotive axial flow leads to
Blower fan cannot reduce hub ratio again and improve compressor flow.Again due to the size limitation of ventilation blower, impeller diameter cannot strengthen.Therefore
Railway locomotive ventilation blower lightweight transformation can only suitably alleviate weight, it is impossible to improve its flow, and it is disadvantageously, general ferrum
Road locomotive lightweight propeller fan volume does not reduce, and simply weight is relatively reduced, and compressor flow does not improve.
Summary of the invention
Solved by the invention technical problem is that, the axial flow proposing a kind of railway locomotive big flow of lightweight compact leads to
Blower fan, this ventilation blower and existing railway locomotive lightweight ventilation blower are compared has weight gentlier, cooling flow during same volume
Bigger.If propeller fan provides existing railway locomotive propeller fan same traffic, volume be can be made smaller, weight
Can be lighter.
The technical solution used in the present invention is, locomotive is with big flow lightweight propeller fan, including in air duct, air duct
Impeller and motor, described air duct is that aluminium alloy is integrally cast, and air duct includes outer air duct, interior air duct and interior air duct and outer
Air duct deflector between air duct, the stator rotor of motor is directly installed on interior air duct.
This propeller fan maximum feature be air duct be aluminium alloy cast structure, air duct is mainly by outer air duct, air duct water conservancy diversion
Plate and interior air duct composition.But interior air duct is also the casing of motor simultaneously.The stator rotor of motor internal is directly installed on endogenous wind
Cylinder is internal, and so interior air duct of casting is far smaller than the interior air duct of conventional axial flow ventilation blower, such as Fig. 2.After in so, air duct reduces
The wheel hub of corresponding draught fan impeller can also reduce, and the length of blade of such impeller is the most elongated, and propeller fan flow is by bright
Aobvious raising.Owing to interior air duct all flows through directly as the casing of motor, all cooling air between inside and outside air duct, such endogenous wind
Cylinder need not add radiating ribs for motor radiating again as motor case, efficiently solves motor radiating problem.
The invention has the beneficial effects as follows, 1. the present invention is to change the air duct of traditional railway locomotive propeller fan into entirety
Cast structure, and air duct inner core is directly as the casing of motor.The casing of fan motor the most of the present invention is directly at ventilation blower stream
In road, the cooling air directly cooled machine casing in ventilation blower runner, motor case is not required to radiating ribs.3. due to the fact that logical
The interior air duct of fan air drum reduces, and the wheel hub of impeller can reduce that (in impeller hub diameter is generally equivalent to air duct, air duct is straight accordingly
Footpath), free height of blade lengthens, and ventilation blower can obtain bigger cooling in the case of profile size constancy, rotating speed are constant
Flow.
Accompanying drawing explanation
Fig. 1 is prior art construction schematic diagram.
Fig. 2 is present configuration schematic diagram.
Figure is labeled as: 1-impeller, the outer air duct of 2-, 3-air duct deflector, air duct in 4-, 5-motor, 9-motor case.
Detailed description of the invention

Existing locomotive is all to be made into by the carbon steel material of original air duct by the method for high-power lightweight axial flow blower loss of weight
High-strength aluminum alloy, changes by the cast iron quality of motor as the methods such as cast aluminium material into, and weight loss effect is not the highest.And ventilation blower
The performances such as cooling flow do not improve.The present invention is that the air duct of traditional railway locomotive propeller fan changes into one piece casting knot
Structure, is directly cast as the casing of motor by the interior air duct 4 of air duct, and the casing of such motor, directly in ventilation blower runner, is ventilated
Cooling air directly cooled machine casing 9 in machine runner, motor case is not required to add radiating ribs.Endogenous wind due to ventilation blower air duct
Cylinder 4 reduces, and the wheel hub of impeller 1 can reduce accordingly, and impeller hub diameter is generally equivalent to air duct diameter in air duct, and blade is the longest
Degree lengthens, and ventilation blower can obtain bigger cooling flow in the case of profile size constancy, rotating speed are constant.Use the present invention

Matter and bearing chamber inlay a series of conventional loss of weight measure rear venting machine profiles such as the structure of carbon steel steel bushing and structure does not changes still
As it is shown in figure 1, performance parameter does not changes yet, weight is 170kg.
As in figure 2 it is shown, the present invention is to maintain this prototype ventilation blower profile interface size constancy, air duct uses ZL205A casting
Aluminum alloy material, outer air duct 2 wall thickness 8mm, air duct water conservancy diversion thickness of slab 3mm, interior air duct is 10mm as the casing thickness of motor, endogenous wind
Cylinder external diameter is 310mm, smooth structure without radiating ribs.Interior air duct need to be by motor case standard entirety machining.Electric motor end cap depends on
Cast aluminium material and bearing chamber is so used to inlay the structure of carbon steel steel bushing.Impeller diameter 665mm, hub diameter 310mm.By the present invention
The ventilation blower of design is similarly 1500Pa at static pressure, and flow can bring up to more than 8.0, and weight reduces to 140kg.
The technology of the present invention compares tradition ventilation machine loss of weight scheme, makes motor case, the most not only between interior air duct
Decrease the weight of interior air duct, also reduce the weight of motor radiating muscle.Compare tradition ventilation machine loss of weight scheme thoroughly to solve
Fan motor heat dissipation problem, it is not necessary to motor carries fan cooling or bypasses the heat radiation of a part of cooling flow.Compare tradition logical
Blower fan loss of weight scheme decreases impeller hub size, not only alleviates ventilation blower weight and also improves the cooling flow of ventilation blower.
