Description
Technical field
The Air compressor of the stable output pressure of the band boosting admission piece of band boosting admission piece, relates to Air compressor technical field.
Background technology
China railways network spreads all over the country, and railway transport of passengers is main stream traffic instrument.
China railways run in 28 days 4 April in 2008 time 41 points, T195 the passenger train that Qingdao is left in descending Beijing moves between Jiao Ji Railway Line Wang Cun to Zhou village and derails, and rushes at outside uplink roadbed.Just when now, 5034 passenger trains brakes in normal Yantai to the Xuzhou run are too late, final clashes into the speed of 70 kilometers per hour and derailing vehicle, and locomotive and 1-5 save compartment derailing.Jiaozhou-Jinan railway train colliding accident has caused 72 people dead, the serious consequence that 416 people are injured.
Therefore, train braking response time is short, and the brake system response time of rail vehicle is the guarantee of safe driving.But the rail vehicle of prior art, because the time of again filling wind after braking is generally 3-5 minute, if ton train employs emergency braking, then air-filled time even can more than 10 minutes.
Train brake is exactly the motion preventing train artificially, comprises and makes it slow down, and does not accelerate or out of service, " brake " that be namely commonly called as.The train braked or locomotive are removed or weakened its brake action, is then called " alleviation ", " declutching " of being namely commonly called as.The equipment set installed ON TRAINS for apply brake and alleviation, is generically and collectively referred to as train " brake ".
When the feature of self acting air damper is brake pipe's air draft (decompression), brake cylinder fills wind (supercharging), alleviates.Action when distributing valve/control cock experiences the pressure drop of brake pipe during brake pipe's air draft, be communicated with brake cylinder by auxiliary reservoir, the pressurized air in auxiliary reservoir is filled with brake cylinder, thus promotes foundation brake rigging and produce braking force.Fill wind process and be divided into two stages, action when distributing valve/control cock experiences the pressure increase of brake pipe in first stage, brake cylinder is communicated to air thus wind in emptying brake cylinder produces remission effect; Subordinate phase, is communicated to air by brake cylinder on the one hand when distributing valve/control cock action, on the other hand brake pipe is communicated to auxiliary reservoir and application reservoir, utilizes the pressurized air in brake pipe to fill wind to these two reservoirs.Advantage is, when train generation separation accident, when brake hose is pulled off, brake pipe's blast sharply declines, and distributing valve/control cock piston moves to retarder location automatically and promptly, therefore train can be braked rapidly until stop automatically.The safety of train operation can be improved, when train accidental separation, can automatic train stop, avoid causing more serious consequence.Therefore, extensively adopt in the railway system of China and world's most countries.
But, the deficiency of this brake of prior art is: when train normally runs brake pipe fill wind or air draft by locomotive control, when brake pipe fills wind, pressurized air can flow to application reservoir and the auxiliary reservoir of this vehicle via the distributing valve/control cock of each vehicle.Because the brake pipe of through full train has certain length, therefore then first said process can occur on vehicle thereafter from the upper generation of locomotive rear portion first car in turn, until last vehicle of train, and all there is certain volume due to the application reservoir of each vehicle and auxiliary reservoir, full train larger with air quantity.On vehicle, all wind regimes all come from locomotive simultaneously.Therefore, when this brake is applied to the longer train of marshalling, self-retention supervisor only to rise when starting to fill wind when being full of to the application reservoir of each car and auxiliary reservoir, the longer time can be needed, the time of again filling wind after usual braking is generally 3-5 minute, if employ emergency braking for the longer ton train of marshalling, then air-filled time even can more than 10 minutes again.Within this time period, if the emergency situation of occurrence injury traffic safety again, when needing braking, this brake normally cannot play braking effect, not have braking force even completely.
The locomotive engine that namely locomotive is commonly called as.
The compartment that namely vehicle is commonly called as.
The effect of foundation brake rigging is by the transmission of power of brake cylinder generation and is assigned on each wheel.
Application reservoir is that distributing valve or each action of control cock all can consume the pressurized air in application reservoir for distributing valve or control cock action provide the wind regime of power.
Electro-pneumatic brake is the abbreviation of electronically controlled pneumatic brake machine, the basis of air damper installs the electric controling parts such as electromagnetic valve additional and is formed.Its feature is that the maneuvering and control of brake action uses " automatically controlled ", but brake action prime power or pressurized air.And when brake automatically controlled malfunctioning for some reason, it is practicable " gas control " (atmospheric pressure control) still, becomes self acting air damper temporarily.At train speed very high or marshalling very long, when air damper is difficult to meet the demands, adopt electro-pneumatic brake greatly can improve the conformability of the braking of train front and rear part and mitigation, significantly alleviate Lognitudinal Impact of Trains, and shortening stopping distance, many high speed trains all have employed electro-pneumatic brake in the world.But because when electro-pneumatic brake fills wind, each vehicle is only controlled by electric signal, the wind regime that it fills needs in wind process still will be provided by locomotive.Even if the auxiliary reservoir of each vehicle and application reservoir can be made under the control of electric signal almost to start to fill wind simultaneously, but it does not always reduce with air quantity, and air-filled time still cannot obtain actv. to be shortened.
As can be seen here, no matter self acting air damper or electro-pneumatic brake after carrying out once alleviating, because the pressure in auxiliary reservoir fails to return to standard value in short time, need to provide enough pressurized airs to brake cylinder during braking, to such an extent as to brake cannot produce enough braking forces, does not have braking effect even completely.
Summary of the invention
On 4.28 accident same day, the uplink and downlink speed limit in incident location was 80km/h, and T195 time descending train rushes speed limit derailing because of misoperation by mistake, and the vehicle accumbency of derailing, on adjacent uplink, now there is no larger injures and deaths.But at this moment No. 5034 trains of up direction are owing to just entering the speed limit section of 80km/h, during the 80km/h that this train is specified to speed limit section by its standard running velocity 120km/h speed governing, used and once braked, to such an extent as to when driver finds the derailing vehicle of on uplink T195 time of accumbency, although take emergency braking measure in time, but once brake owing to just using, the auxiliary reservoir compressed air of each vehicle not yet reaches standard pressure cannot provide sufficient pressurized air to cause braking unable for brake cylinder, cause 5034 Train Stoppings not as good as the derailing vehicle knocking T195 time.Just result in 72 people dead, the tragedy that 416 people are injured just because of this Secondary Shocks.
To trace it to its cause not human accident completely, but because of the deficiencies in the prior art---" air-filled time again after braking is long " result in the second accident occurred in succession.
For overcoming prior art, then it is slow to fill wind speed degree, and the object of the application is for increase is filled airspeed, shortened air-filled time again.The application adopts following technical scheme for this reason:
