The utility model comprises a right engine casing whose one end is provided with an air inlet and a left engine casing whose one end is provided with an air outlet. The left and the right engine casings are mutually connected, while the inner wall of the left engine casing is firmly spaced at interval with a baffle plate. A guide shell is fixed on the baffle plate, while the electric motor of the draught fan is positioned in the engine casing and fixed on the guide shell; the output shaft of the electric motor of the draught fan is fixed with a diagonal impeller. The utility model has the advantages of high efficiency, stable performance, low noise, compact structure, small volume and convenient mounting. The utility model has filled up the blankness of the cooling ventilator of the wave filtering reactor for the home-made AC locomotive. With regard to the refrigerant wave filtering reactor after inspection, the rising value of the temperature is controlled within the fixed scope.
Description
Technical field
The utility model relates to a kind of ventilator, particularly is used for the diagonal flow type ventilator that the city rail trolley filter reactor ventilates and cools off.
Background technique
The whole dependence on import of ventilator that filter reactor cooling channel on the existing homemade city rail trolley is used are provided by some big internationally famous companies such as Japanese Japan, Hitachis.These import ventilator structure relative complex cost an arm and a leg.
Summary of the invention
The utility model is in order to solve the filter reactor ventilator dependence on import on the existing homemade city rail trolley, and imported product structure relative complex, expensive problem provide a kind of novel track car filter reactor diagonal flow type ventilator.
The utility model is to adopt following technological scheme to realize: the diagonal flow type ventilator, comprising an end is the right casing of intake grill and the left casing that an end is exhaust outlet, left and right casing is coupled to each other, left side casing inner wall fixed interval has guide plate, be fixed with guide shell on the guide plate, fan motor is positioned at casing and is fixed on the guide shell, is fixed with diagonal impeller on the output axle head of fan motor.This diagonal flow type ventilator is installed in the bottom of locomotive.Fan motor drives the diagonal impeller running, and extraneous cool air sucks by the intake grill of right shell body, and in casing through the speed-raising of boosting, send from the exhaust outlet of left casing through behind the air conducting tube again, filter reactor is implemented to ventilate cools off.Guaranteed that filter reactor can work under normal temperature, filter reactor is unlikely to because of overheated scaling loss.
The intake grill of right casing is fixed with air inlet louvers.The exhaust outlet of left side casing is fixed with flexible duct.Flexible duct the fixing of ventilator and filter reactor of being more convenient for is set, can guarantees that by flexible duct cooling blast can send into each position of filter reactor equably simultaneously; Flexible duct can guarantee effectively that in the locomotive operation process locomotive speed changes and produces when vibrating can be filter reactor air-supply cooling normally, and has effectively prolonged the working life of filter reactor.
The application of diagonal flow type ventilator described in the utility model success the boundary layer control theory, adopt meridian accelerating type runner, make specific speed circle of blower fan between centrifugal fan and axial fan, have the higher and higher characteristics of centrifugal fan pressure coefficient of axial fan flow coefficient concurrently.It is low to have efficient district broadness, stable performance, noise simultaneously, compact structure, and volume is little, advantage easy for installation.Filled up the blank of domestic AC locomotive filter reactor with cooling fan.
In actual test process, diagonal flow type ventilator described in the utility model, its flow are Q=40m
3/ min, total head is P=196Pa.What be cooled is the 11Q12 filter reactor, and after installing and using on the locomotive, the 11Q12 filter reactor uses normally after testing, and temperature rise value is controlled within the scope of regulation.

Embodiment
The diagonal flow type ventilator, comprising an end is the right casing 1 of intake grill and the left casing 2 that an end is exhaust outlet, left and right casing is coupled to each other, left side casing 2 inwall fixed interval have guide plate 3, be fixed with guide shell 4 on the guide plate 3, fan motor 5 is positioned at casing and is fixed on the guide shell 4, is fixed with diagonal impeller 6 on the output axle head of fan motor 5.Adopt flange to connect between the left and right casing.The intake grill of right casing 1 is fixed with air inlet louvers 7, and the employing flange connects between air inlet louvers 7 and the right casing.The exhaust outlet of left side casing 2 is fixed with flexible duct 8, and the employing flange connects between flexible duct 8 and the left casing 2.On casing, be fixed with mounting bracket 9, bolt 10 is set on the mounting bracket 9, be with rubber damper 11 on the bolt 10.By bolt 10 that the mounting bracket on the ventilator 9 is fixing with the vehicle mounting bracket 12 of locomotive bottom, to realize ventilator fixing in the locomotive bottom, rubber damper 11 can guarantee effectively that vertically having acceleration at locomotive is not more than 30m/s
2Vibration damping requirement during impact can effectively protect filter reactor to exempt from infringement when locomotive running vibration.
During concrete the manufacturing, fan motor 5 adopts YJTP series 90S--4 type 1.1kW motor, and its mounting type is the B3 mounting type.Left and right sides casing through the spinning lathe rotary press modelling, makes left and right sides casing beautiful shape, the flange unanimity by the monoblock steel plate.The wheel hub of diagonal impeller 6 adopts the monoblock steel plate through the spinning lathe rotary press modelling, no weld seam, and the intensity height, molded lines is carefully and neatly done, and blade adopts steel plate cutting, through compression molding, forms diagonal impeller through weldering tire and wheel hub assembly welding again.Check through dynamic and static balance then, make impeller reach higher balance quality.Air conducting tube 4 adopts the monoblock steel plate through the spinning lathe rotary press modelling, no weld seam, and the intensity height, molded lines is carefully and neatly done, and guide plate 3 welds in air conducting tube after mould compression moulding, can uniformly and effectively cooling air be blown into each position of filter reactor.Air inlet louvers 7 discs and plane are all adopted and are crossed chromium screen deck net and flange welding fabrication.Flexible duct 8 adopts base cloth to be resistant to elevated temperatures and to have 840 deniers than high scalability, the intensified nylon fiber of 22 orders/25.4mm, the two-sided chlorosulfonated polyethylene rubber of soaking, blanking after the accurate Calculation size is then with inclined-plane sewing, the bonding method of mighty bond, through the fixing aftershaping of flange.Can guarantee locomotive when normal operation vertical, vertical and when laterally to have frequency be the sinusoidal vibration of 1～50Hz and the normal air-supply during temperature variation.
When fan motor 5 drives diagonal impeller 6 runnings, extraneous cool air at first sucks by air inlet louvers 7, and in casing through the speed-raising of boosting, pass through air conducting tube 4 again after, thereby guarantee that cooling blast can send into each position of filter reactor 13 uniformly by flexible duct.
