Abstract
The utility model relates to a centrifugal ventilating fan, which particularly relates to an axial centrifugal ventilating fan for a locomotive pulling motor. The utility model aims at providing an axial centrifugal ventilating fan for a locomotive pulling motor, which integrates the characteristics of an axial flown fan and a centrifugal fan to lead the utility model to have compact structure and light weight, and be easy to be mounted. The utility model comprises a main air duct, which is characterized in that a rear-bend type centrifugal vane wheel and a drive motor are mounted in the main air duct, the centrifugal vane wheel is pressed and mounted on the extension portion of a drive motor shaft, and an air inlet duct is also mounted on the main air duct. The centrifugal ventilating fan is mainly used for the wind supplying and the cooling of the locomotive pulling motor.
Description
Technical field
The utility model relates to a kind of centrifugal blower, relates in particular to the axial centrifugal blower of a kind of locomotive traction motor.
Background technique
The traction electric machine blower fan of former employing on the locomotive has two kinds, a kind of is propeller fan, another kind is a centrifugal blower, traditional propeller fan is because of its pneumatic design reason, noise is bigger, the pressure that produces is not high, originally the fan noise that uses on the locomotive requires generally about 108-115dB, and total head is below 2000Pa, be difficult to satisfy the demand for development of locomotive low noise and high pressure, and traditional centrifugal blower is because of its reasons in structure, volume, weight is bigger, and its turnover air flue structure is comparatively complicated, is difficult to satisfy the requirement of the light and compact structure aspect of locomotive weight.
Summary of the invention
The purpose of this utility model is to provide a kind of locomotive traction motor axial centrifugal blower, this blower fan structurally combines the characteristics of propeller fan and centrifugal blower, make the blower fan structure compactness, in light weight, be convenient to install, and can meet the demands aspect low noise and the high pressure.
Technical solution of the present utility model is: the axial centrifugal blower of locomotive traction motor, comprise main wind tube, it is characterized in that: in the described main wind tube, centrifugal impeller and drive motor are installed, centrifugal impeller is fitted on the extending part of drive motor axle, and air inlet duct also is installed on the main wind tube.
Described centrifugal impeller is the back curved centrifugal impeller.
The utility model has the advantages that: it structurally combines the characteristics of axial-flow blower and centrifugal blower, make this locomotive traction motor with axial centrifugal blower have compact structure, in light weight, be convenient to advantages such as installation.Because the wheel speed height, the axial flow of the axial flow fan vane wheel that the pressure ratio that radial air flow forms is traditional is big, so its pressure ratio axial-flow blower height; Again because of blower fan adopts the back curved centrifugal impeller, the vortex motion that can effectively reduce airflow breakaway and produced, thereby the noise ratio axial-flow blower is low, can satisfy the low noise environmental requirement, noise is less than 103dB, and pressure makes blower fan of the present utility model satisfy the requirement of locomotive development well up to 3200Pa.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-air inlet duct, 2-back curved centrifugal impeller, 3-main wind tube, 4-inner core, the axial stator of 5-, 6-drive motor.
Embodiment
Below in conjunction with accompanying drawing the utility model and embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises main wind tube, it is characterized in that: in the described main wind tube 3, centrifugal impeller 2 and drive motor 6 are installed, centrifugal impeller 2 is fitted on the extending part of drive motor axle, and air inlet duct 1 also is installed on the main wind tube 3.
Described centrifugal impeller 2 is back curved centrifugal impellers.
Drive motor 6 is installed in blower fan main wind tube 3, guarantee that by the seam location drive motor axle is concentric with the air duct internal diameter, with bolt motor is fastened in the main wind tube 3, back curved centrifugal impeller 2 is fitted on the extending end of the motor shaft that flat key is housed, air inlet duct 1 is installed on the main wind tube 3, after starting blower fan, drive motor 6 drives back curved centrifugal impeller 2 high speed rotating, air-flow sucks from air inlet duct 1, after speed increase and pressure rising, by exporting by the axial outlet of main wind tube 3 after axial stator 5 rectifications.
Claims (2)
1. axial centrifugal blower of locomotive traction motor, comprise main wind tube, it is characterized in that: in the described main wind tube (3), centrifugal impeller (2) and drive motor (6) are installed, centrifugal impeller (2) is fitted on the extending part of drive motor axle, and air inlet duct (1) also is installed on the main wind tube (3).
