The technological means that the present invention adopts is as follows:
The centrifugal axial flow traction ventilator of a kind of use for electric locomotive, is characterized in that:
Comprise one and be vertically arranged on air conducting tube in electric locomotive, described air conducting tube comprise outer air duct be connected with by rear guide vane in air duct, the bottom of described outer air duct is provided with terminal box;
One slip ring be connected with the end flanges of described outer air duct by counter flange;
One is arranged on the motor on the interior air duct flange of described interior air duct;
One is fixed on the centrifugal blower fan blade wheel on the motor shaft of described motor, the impeller front disc of described centrifugal blower fan blade wheel is the cambered surface extended to described outer air duct direction from the position connected with described slip ring, and impeller hub disk is the inclined-plane extended to described centrifugal blower fan blade wheel central position from the position connected with described interior air duct; Described impeller front disc and described impeller hub disk form a diffusion runner tilted;
One air guide sleeve to be fixed in described centrifugal blower fan blade wheel in the heart.
The design form of above-mentioned centrifugal blower fan blade wheel more impels the air-flow flowed out from centrifugal blower fan blade wheel runner more easily to turn to axial flow.
Further, the inclined-plane inclined angle alpha of described impeller hub disk is described impeller hub disk and radial angle, and described inclined-plane inclined angle alpha is determined by the static pressure of described ventilator and axial dimension, described inclined-plane inclined angle alpha value between 5 °-45 °.Design static pressure is lower, axial dimension nargin is larger, then inclined-plane inclined angle alpha is larger, otherwise, then less.
Further, the outlet of described centrifugal blower fan blade wheel is tilting outlet, form blade exit angle of inclination beta with axial, described blade exit angle of inclination beta is determined by the inside and outside air duct diameter ratio of static pressure and ventilator, described blade exit angle of inclination beta value between 10 °-35 °.Under the prerequisite of restriceted envelope size, design static pressure is higher, then blade exit angle of inclination beta is less; Inside and outside air duct diameter is than larger, then blade exit angle of inclination beta is larger.The design of above-mentioned tilting outlet makes the diameter dimension from the nearest impeller hub disk of interior air duct less, be conducive to suppressing air-flow from radial steering shaft to time the separation of flow that causes.
Further, the outside of described blades front disk is provided with guide plate, and described guide plate coordinates with described outer air duct makes the air flowed out near described impeller front disc transfer axial flow to gradually.
Air conducting tube will be converted to pressure energy airflow kinetic energy, and reduces the energy loss in conversion process of energy, improves static pressure efficiency.And guide plate and coordinating of outer air duct can force the air flowed out near impeller front disc to transfer axial flow gradually to, air can be greatly reduced to reflux forward simultaneously, alleviate the eddy current earthquake intensity of air in the chamber that slip ring, impeller front disc and exogenous wind cylinder are formed, reduce energy loss, improve fan efficiency.
