Abstract
The invention provides a pneumatic flameout device for a bus engine. The pneumatic flameout device for the bus engine comprises a power switch, a fuse box, a pneumatic valve, a flameout handle, an air cylinder, a pneumatic pump, an inflation pump and the engine. The power switch, the fuse box and the pneumatic valve are in circuit connection in sequence. The inflation pump, the air cylinder, the pneumatic valve and the pneumatic pump are sequentially connected through air passages. The engine is connected with the inflation pump in a bus-mounted mode. The pneumatic pump controls the flameout handle through an air passage. The pneumatic valve is a pneumatic electromagnetic valve. The working time of the pneumatic flameout device is short, and thus neither high temperature nor large abrasion can be generated, and the possibility that the pneumatic flameout device is damaged when used normally is extremely low. The repair difficulty is low, and damage mainly happens to the air passages and can be well avoided by replacing sealing parts such as an O-shaped ring. Cost is low, and the price of the whole pneumatic flameout device is about 120 yuan.
Description
Technical field
The present invention relates to the pneumatic blanket of a kind of bus engine, belong to bus engine control technique field.
Background technique
Bus in use for some time, there will be engine extinction device aging, need to change with the normal use ensureing vehicle, but the engine extinction device of bus is all generally electromagnetism blanket as shown in Figure 1 in prior art, the working principle of this electromagnetism blanket is, when rotating key and switching on power, key control power switch 101 ' is closed makes fuse box relay 102 ', delay-time protector 103 ' obtains electric, during vehicle launch, starting motor works, inhaled circuit energising FS-solenoid 201 ' upper wink simultaneously, FS-solenoid 201 ' is worked and pulls flame-out handle 202 to working position, start to start, when flame-out, when closing key, supply disconnecton, FS-solenoid 201 ' is by the strength return of spring, promote flame-out handle 202 to flame-out position, motor 301 is stopped working.
In this mode of operation; fuse box relay 102 ', delay-time protector 103 ' and FS-solenoid 201 ' are long for current"on"time; and work long hours electronic product can be made to produce high temperature and fragile; have a strong impact on working life; and only equipment price is just more than 1200 yuan for this electromagnetism blanket, and replacement cost is high, and once damage; it repairs difficulty greatly, and the cost paid required for reparation may far above replacement cost.
Summary of the invention
For solving the problems of the technologies described above, the invention provides the pneumatic blanket of a kind of bus engine, the pneumatic blanket of this bus engine, by the pneumatic setting such as pneumatic valve, pneumatic pump, ensure that extremely low replacement cost, extremely low damage possibility, minimum wearing and tearing.
The present invention is achieved by the following technical programs.
The pneumatic blanket of a kind of bus engine provided by the invention, comprises power switch, fuse box, pneumatic valve, flame-out handle, gas receiver, pneumatic pump, inflating pump, motor; Described power switch, fuse box, pneumatic valve successively circuit connect; Described inflating pump, gas receiver, pneumatic valve, pneumatic pump successively air flue connect; The vehicle-mounted connection inflating pump of described motor; Described pneumatic pump air flue controls flame-out handle; Described pneumatic valve is air-operated solenoid valve.
Described power switch is self-return power switch.
In described flame-out handle, return spring is set, makes flame-out handle capable of being return and remain on enable position.
Described pneumatic pump air flue controls flame-out handle, the push rod control of the handle that stopped working by the gas piston linkage in pneumatic pump.
Beneficial effect of the present invention is: 1. the operating time is short, can not produce high temperature, and also do not have too large wearing and tearing, the possibility damaged because normally using is minimum; 2. repair difficulty low, damage and mainly occur in air flue, by changing as the Sealings such as O type circle can well solve; 3. with low cost, a whole set of cost price is at about 120 yuan.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of prior art.
In figure: 101-power switch, 102-fuse box, 201-pneumatic valve, 202-stops working handle; 203-gas receiver, 211-pneumatic pump, 212-inflating pump, 301-motor; 101 '-key controls power switch, 102 '-fuse box relay, 103 '-delay-time protector, 201 '-FS-solenoid.
Embodiment
Further describe technological scheme of the present invention below, but described in claimed scope is not limited to.
The pneumatic blanket of a kind of bus engine as shown in Figure 1, comprises power switch 101, fuse box 102, pneumatic valve 201, flame-out handle 202, gas receiver 203, pneumatic pump 211, inflating pump 212, motor 301; Described power switch 101, fuse box 102, pneumatic valve 201 successively circuit connect; Described inflating pump 212, gas receiver 203, pneumatic valve 201, pneumatic pump 211 successively air flue connect; The vehicle-mounted connection inflating pump 212 of described motor 301; Described pneumatic pump 211 air flue controls flame-out handle 202; Described pneumatic valve 201 is air-operated solenoid valve.
Described power switch 101 is self-return power switch.
In described flame-out handle 202, return spring is set, makes flame-out handle 202 energy return and remain on enable position.
Described pneumatic pump 211 air flue controls flame-out handle 202, the push rod control of the handle 202 that stopped working by the gas piston linkage in pneumatic pump 211.
Thus, switch on power when opening key, across-the-line starting motor 301 works, because flame-out handle 202 is provided with return spring, therefore flame-out handle 202 remains on enable position and does not affect the starting of motor 301, when flame-out, press power switch 101, through circuit relay and the safety protection of fuse box 102, pneumatic valve 201 is energized and opens gas circuit, the gas in gas receiver 203 is discharged in pneumatic pump 211 work, flame-out handle 202 is promoted to flame-out position by the piston in pneumatic pump 211, motor 301 is caused to stop working, after power switch 101 self-return, pneumatic valve 202 and pneumatic pump 211 quit work, flame-out handle 202 is repositioned to enable position, inflating pump 212 is inflated in gas receiver 203.
In cost price, electromagnetism blanket is more than 10 times of the present invention.
On in use, suppose that the working life of electromagnetism blanket is 2400 hours, every day time that motor 301 operates calculates 8 hours, electromagnetism blanket works 8 hours simultaneously, so can use 300 days, namely less than 1 year, and deposit in use produce high temperature can damage at any time.Suppose that working life of the present invention is also 2400 hours, time now because time the present invention of engine running does not work without the need to considering engine running, if go out car every day 12 times, just need flame-out 12 times, as long as each 3 seconds at most, 36 seconds every days, so 4000 days can be used, nearly 11 years, reach at vehicle and scrap the time limit and also can not damage.
In maintenance, after electromagnetism blanket damages, not having the equipment of too specialty and too large cost not to repair, is all generally change assembly; And after the present invention's damage, maximum possible is exactly change the O type circle of pneumatic pump 211, general driver just can repair.
