Abstract
The invention relates to a ventilator, in particular to an inclined flow ventilator for a subway locomotive filter reactor. By using the inclined flow ventilator, the technical problems that the air volume of the ventilator for the current subway locomotive filter reactor is not high, the air-out is not stable are solved. The inclined flow ventilator for the subway locomotive filter reactor comprises a barrel-shaped enclosure, wherein a guide cylinder, a centrifugal impeller and a motor driving the centrifugal impeller are arranged inside the enclosure in sequence; the rotating shaft of the centrifugal impeller is parallel with the axial direction of the enclosure; the projection of blades of the centrifugal impeller on a vertical plane on which the normal of the blades is vertical to the axial direction of the enclosure forms an included angle of 20-40 degrees with the vertical direction; the included angle faces to the air-out direction; the guide cylinder is in a structure contracting inwards; and the distance between the contracting end of the guide cylinder and the center axis of the enclosure is smaller than the spacing between the top ends of the blades of the centrifugal impeller and the central axis of the enclosure. Due to the combination of the centrifugal impeller and the axial flow enclosure, the air volume is high, the air-out is stable, and the filter reactor is guaranteed to work under normal temperature when a subway locomotive operates.
Description
Technical field
The present invention relates to ventilator, be specially a kind of underground engines filter reactor diagonal flow type 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 big railway locomotive factory produces, employed filter reactor is had relatively high expectations to the cooling of ventilating, the requirement air-out is steady and wind flow is big, and the ventilator that uses at present is difficult to satisfy above-mentioned requirements, therefore need the ventilator that a kind of air-out is steady, air quantity is big, to satisfy the ventilation needs of underground engines filter reactor.
Summary of the invention
The present invention provides a kind of underground engines filter reactor diagonal flow type ventilator for solving the used ventilator air quantity of present underground engines filter reactor big, air-out technical problem stably inadequately inadequately.
The present invention realizes by the following technical solutions: a kind of underground engines filter reactor diagonal flow type ventilator comprises the tubular casing that is provided with inlet, outlet; The motor that is provided with guide shell, receded disk impeller in turn and drives receded disk impeller to the exhaust outlet direction by intake grill in the 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 ° at its normal and enclosure axis projection and the angle of vertical direction on the vertical vertical plane; Described guide shell is inside closing in structure, and the closing in end distance is disembarked the distance of shell central shaft less than the top of receded disk impeller blade and the spacing of casing central shaft.
The diagonal flow type ventilator is installed in the locomotive bottom during use, 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 its normal and enclosure axis on the vertical vertical plane (being Fig. 1 paper) projection and the angle a of vertical direction be that (angle as shown in Figure 1 a) for 20 ~ 40 degree, the air that is entered by intake grill flows at the inwall to casing that the effect of receded disk impeller has a down dip like this, 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 exhaust outlet vertically, realized adopting the receded disk impeller air-out and air-out direction along the axial air-out mode of casing, air output is big 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, the kinetic energy with the deflection air-flow is converted into static energy simultaneously.Its static pressure efficiency significantly improves, and makes 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 present invention adopts receded disk impeller and axial flow casing to combine, and has the higher and centrifugal fan pressure coefficient advantage of higher of axial fan flow coefficient concurrently; Air output is big and air-out is steady, has guaranteed that filter reactor can work under normal temperature when underground engines turns round, and filter reactor is unlikely to because of overheated scaling loss.The present invention can also be used for other device that cooling of ventilating is had relatively high expectations.
