Abstract
The utility model relates to a ventilator, in particular to a diagonal-flow ventilator for a metro locomotive filter reactor. The technical problem that the ventilator for the existing metro locomotive filter reactor is small in air volume and unstable in air outgoing is solved. The diagonal-flow ventilator for the metro locomotive filter reactor comprises a barrel-shaped casing. A flow guiding barrel, a centrifugal impeller and a motor driving the centrifugal impeller are sequentially arranged in the casing. A rotary shaft of the centrifugal impeller is axially parallel to the casing, an included angle formed by projection of blades of the centrifugal impeller on a vertical plane where the blade normal is axially perpendicular to the casing and the vertical direction is 20-40 degrees, and the blades face the air outgoing direction. The flow guiding barrel is of an inward closing-up structure, and a distance from the closing-up end to a central shaft of the casing is smaller than a separation distance between the top ends of the blades of the centrifugal impeller and the central shaft of the casing. The centrifugal impeller and the axial-flow casing are combined, the air volume is large, the air outgoing is stable, and the filter reactor is ensured to be capable of working at normal temperature during operation of a metro locomotive.
Description
Technical field
The utility model relates to ventilator, is specially a kind of underground engines filter reactor diagonal flow ventilator.
Background technique
The alternating current electric locomotive of the employing inverter power supply that is used for the city rail operation that existing domestic each large railway locomotive factory produces, the filter reactor that uses is to cooling the having relatively high expectations of ventilating, the requirement air-out is steady and wind flow is large, and the ventilator that uses at present is difficult to meet above-mentioned requirements, therefore need the ventilator that a kind of air-out is steady, air quantity is large, to meet the ventilation needs of subway locomotive filter reactor.
Summary of the invention
Present underground engines filter reactor ventilator air quantity used is large not in order to solve for the utility model, air-out technical problem not stably, and a kind of underground engines filter reactor diagonal flow ventilator is provided.
The utility model is realized by the following technical solutions: a kind of underground engines filter reactor diagonal flow ventilator comprises the tubular casing that is provided with inlet, outlet; The motor that is provided with in turn guide shell, receded disk impeller and drives receded disk impeller to the exhaust outlet direction by intake grill in described casing; The rotating shaft of described receded disk impeller and the parallel to an axis of casing, the blade of receded disk impeller is a and towards air-out direction, angle a size is 20 ~ 40 ° in its normal and enclosure axis to the angle of the projection on vertical vertical plane and vertical direction; Described guide shell is inside closing-in structure, the end that closes up apart from the distance of casing central shaft less than the top of receded disk impeller blade and the spacing of casing central shaft.
During use, diagonal flow ventilator is arranged on the locomotive bottom, and exhaust outlet is aimed at filter reactor.The blade of receded disk impeller is to the Way out deflection, the blade of receded disk impeller is that (angle as shown in Figure 1 a) for 20 ~ 40 degree in its normal and enclosure axis to the projection on vertical vertical plane (being Fig. 1 paper) and the angle a of vertical direction, the air that is entered by intake grill like this flows at the inwall to casing that the effect of receded disk impeller has a down dip, and most ofly blows out to exhaust outlet under the stopping of casing; Again because guide shell is the closing in shape, and the closing in end of guide shell and the spacing of casing central shaft are less than the spacing of blade tip and central shaft, wind through receded disk impeller rotation direction casing inner wall can only blow to exhaust outlet under the stopping of guide shell, and can't flow out through intake grill.The angle design of blade and the effect of guide shell make the air that enters casing through intake grill to blow to vertically exhaust outlet, realized adopting the receded disk impeller air-out and air-out direction along the axial air-out mode of casing, air output is large and blast is also high.Motor is supported in casing inside by dunnage.
Further, casing inner wall is provided with the guide vane of equidistantly arranging of wound motor and connection motor and casing inner wall.
The effect of guide vane be the deflection air-flow pivot of maneuver that flows out impeller to, be static energy with the kinetic transformation of deflection air-flow simultaneously.Its static pressure efficiency significantly improves, and make the highest total pressure efficiency operating point of blower fan and the highest static pressure efficiency operating point closer to each other.Guide vane can play the effect of fixed electrical machinery simultaneously.
The utility model adopts receded disk impeller and axial flow casing to combine, and has the higher and higher advantage of centrifugal fan pressure coefficient of axial fan flow coefficient concurrently; Air output is large and air-out is steady, has guaranteed that filter reactor can work when underground engines turns round under normal temperature, and filter reactor is unlikely to because of overheated scaling loss.The utility model can also be used for other to the cooling device of having relatively high expectations that ventilates.
