Description
Technical field
Sound energy change type VMC, relates to ventilation of passenger train field.
Background technology
China railways network spreads all over the country, and railway transport of passengers is still main stream traffic instrument.For a long time, railway transport of passengers passenger flow volume is large, and particularly in the spring transportation summer transportation phase, common attending a banquet is usually full or overcrowding delivery, and crowded passenger is in narrow compartment, and air quality can decline.Regulating for utilizing natural wind makes fresh air enter compartment, the Chinese patent CN202006797U patent of prior art, due to its fresh wind tube 1 and the version of exhaust duct 2, two-way confession 10 place's bending, the pressure reduction between fresh wind tube 1 and exhaust duct 2, by the local resistance loss of 10 bendings, almost approach exhaustion, ventilation effect is very poor, unless fresh wind tube 1 is enough large with the pipe diameter of exhaust duct 2, thus, vehicle operating resistance will increase greatly.By also finding out in its specific embodiment that " be set as by the cross sectional dimensions of exhaust duct (1): 800mm × 300mm, the cross sectional dimensions of fresh wind tube (2) is set as: 500mm × 150mm." will higher than roof 1200 ~ 1400mm, this has highly exceeded the railway clearance standard of China and world's most countries, serious harm traffic safety.According to the regulation of " People's Republic of China's railway technology code " accompanying drawing 2, the height in compartment is less than 4800mm from railroad track end face to vehicle roof equipment vertex.The height of the main flow passenger vehicle 25G type vehicle that China railways is current is 4433mm, if use the height of this equipment vehicle will more than 5633mm, this will overturn the rolling stock clearance standard of China, to cannot implement in China and world's most countries at all, such technical scheme, redesign existing vehicle (if change height of car comprehensively, entire vehicle intensity will be affected, must all redesign), improve the height of railway auxiliary building, as: tunnel, bridge, platform canopy, contact system (electric locomotive high voltage supply line) and garage door etc.In addition, the fresh-air ventilation mouth " fresh wind tube 1 " in CN202006797U is all the fresh wind tube in face of wind, and inlet-duct area determines ventilation volume, and the resistance in train driving like this will strengthen greatly, and train entirety must redesign.In other words, to increase the air interchanger as described in CN202006797U patent on existing train, the redesign of the vehicle in using repacking must be run by existing.
The Chinese patent of prior art: CN2811045Y, is only applicable to automobile, is not suitable for the two-way train started.
Summary of the invention
From the nineties in last century, air-conditioning passenger train rises gradually, air-conditioned coach is that door and window closes, but the idea of people still rests on the epoch of old passenger train, thinks that having had air-conditioning to close door and window can lean on air-conditioning also to supplement fresh air in compartment together except refrigeration.In recent years, air-condition faults happens occasionally, and as 12:27 on May 8th, 2011 divides, to D94 motor train unit train of Hongqiao, stop because a/c system et out of order is forced in station, rivers and mountains in Nanchang; On July 19th, 2009, K226 the train in Lanzhou was left for because of a/c system fault in Guangzhou, can not provide fresh air at about 8 pm, and cause passenger uncomfortable because of unhappy in compartment, what have goes into hospital.This is train fault together, causes visitor to hinder accident owing to not pulling at that time to stop.Such accident is too numerous to enumerate.

Beneficial effect
1, " negative pressure ventilation pipe 2 top connects negative pressure valve 1, and negative pressure valve 1 top is the streamline cambered surface of evagination, and negative pressure valve 1 top is at roof, and negative pressure ventilation pipe 2 passes roof apparatus storehouse lower nozzle in compartment.", " positive airway pressure pipe 4 top connect roof, positive airway pressure pipe 4 lower end through roof apparatus storehouse lower nozzle in compartment." due to negative pressure valve 1 top be the streamline cambered surface of evagination; gas is at the large faceted Top Skin 15 of negative pressure valve 1 top flowing velocity; produce negative pressure; the foul smell in compartment is sucked out outside compartment; when foul smell is constantly sucked out outside car; when in compartment, pressure is less than external pressure, and the fresh air outside compartment is inhaled in compartment by positive airway pressure pipe 4 and supplements, and reaches the effect of ventilation.
2, negative pressure ventilation pipe 2 is straight tube, and drag losses is little, and ventilation effect is good.According to " Principles of Chemical Engineering " Wang Zhikui-chapter 1 table 1-2 pipe fitting and the coefficient of local resistance of valve member and the value of equivalent length, the local resistance loss checking in 90 ° of elbows be equivalent to the ratio of equivalent length and caliber 35 (see)
Principles of Chemical Engineering
The coefficient of local resistance of table 1-2 pipe fitting and valve member and equivalent length value (for turbulent flow)
3, positive airway pressure pipe 4 is the pipe of the horn shape that forward voltage diode upper orifice 4-1 little forward voltage diode lower nozzle 4-2 is large, drag losses can be reduced further, according to Principles of Chemical Engineering fluid energy transfer principle, positive airway pressure pipe 4 upper end is that forward voltage diode upper orifice 4-1 is little, the flare tube that lower end forward voltage diode lower nozzle 4-2 is large:
Lower end forward voltage diode lower nozzle 4-2 is large, and flow is constant, and linear flow speed declines, and static energy raises, and promotes dynamic increasing, and is therefore conducive to the outer fresh air of car and enters in compartment.
4, negative pressure ventilation pipe 2, positive airway pressure pipe 4 are corrosion-resistant steel smooth pipe.From fluid mechanics, friction coefficient λ is the important parameter of the resistance to flow of fluid, and fluid is when transition flow or turbulent flow:
The impact of the resistance of visible relative roughness fluid flow.
5, Top Skin is equipped with automatic watertight door assembly 10 for 15 times, can close negative pressure ventilation pipe 2 and positive airway pressure pipe 4 time rainy.
6, " negative pressure ventilation pipe 2, positive airway pressure pipe 4 are all at train top " is due to the sound energy change type VMC of the application, for stand-by system during power supply trouble, when opening without air-conditioning in car be no matter so due to sunshine or personnel crowded, cause temperature in compartment higher than outside compartment at last, foul smell rises, ozone temperature, lower than the temperature in compartment, therefore enters compartment and flows downward, reach the effect of full compartment fresh air ventilation.
7, negative pressure valve 1 is 60 ~ 100mm higher than Top Skin 15.Lower than Air conditioning unit, after therefore increasing the device of the application, the height overall of vehicle can not be made to increase, guarantee driving safety.
8, simple in structure and low in cost.
