Background technology
It is as follows that current city rail vehicle promptly rises bow air supply device principal feature:
At present, domestic city rail vehicle promptly rises the bow air feed, as shown in Figure 1, and main foot pump or the motor driven compressor pump wind of adopting separately.Wherein foot pump operation inconvenience, the only a few city rail vehicle promptly rises the bow air feed and adopts motor driven compressor separately but do not have automatic air feed controllable function, and motor driven compressor discharge capacity that adopts and motor-driven power thereof are excessive, and (specified free air capacity is 70L/min, rating horsepower is greater than 500W), be not suitable for city rail vehicle and promptly rise the requirement of bow air feed.
Summary of the invention
At above-mentioned prior art, the present invention aims to provide a kind of city rail vehicle and promptly rises electronic air supply device of bow and control method correspondingly, can realize that city rail vehicle promptly rises the automatic air feed of bow; And device is realized simply, wind supply quantity is suitable.
For achieving the above object, the basic technical scheme that the present invention takes is that a kind of city rail vehicle promptly rises the electronic air supply device of bow, comprises air compressor, the invention is characterized in that the supply line of described air compressor is provided with pressure controller; Described air compressor inserts air supply device through check valve by connecting tube, is provided with safety valve in the connecting tube that inserts air supply device.
Wherein pressure controller is one to be arranged on the pressure switch on system's air-supply pipeline, and the supply line of described air compressor comprises relay that is connected in series with pressure switch and the connecting wire that inserts power supply.
Rising the electronic air supply device of bow with above-mentioned rail vehicle emergency is that the present invention also provides a kind of city rail vehicle promptly to rise the autocontrol method of the electronic air supply device of bow, comprises the steps: accordingly
1) pressure switch is moved according to the blast on the air-supply pipeline: when the blast in the air-supply pipeline is lower than specified value, and the pressure switch contact closure, when the blast in the air-supply pipeline was higher than specified value, pressure switch contact disconnected;
2) pressure switch action control relay action: when pressure switch contact is closed, the relay adhesive, when pressure switch contact disconnected, relay disconnected;
3) actuating of relay control compressor start and stop: when the relay adhesive, air compressor starts beats wind, and when relay disconnected, air compressor stopped to beat wind.
Principle of work of the present invention is described as follows: the city rail vehicle of being made up of said structure promptly rises in the electronic air supply device of bow pressure switch as pressure controller according to system's blast action, when blast is lower than certain value, the pressure switch contact closure, the cutin relay power supply, relay contact closure, the conducting of air compressor motor power supply, air compressor start beats wind; When pressure is higher than certain value, the pressure switch action, its contact open relay power, relay contact disconnects, and disconnects air compressor motor power supply, and air compressor stops to beat wind automatically, thereby realizes the automatic guidance of air feed blast.The check valve that is arranged on the wind pipe of air compressor can prevent that pressurized air from oppositely filling wind to compressor.Being installed in the described system safety valve on the connecting line can surpass the automatic air draft of specified value at blast, carry out overvoltage protection to system.
City rail vehicle of the present invention promptly rises electronic air supply device of bow and control method correspondingly, can be according to system's blast automatic guidance air compressor start and stop, realized that city rail vehicle promptly rises the automatic air feed of bow, and wind supply quantity is suitable, the motor driven compressor power demand is little, cleanliness without any pollution.

The specific embodiment
Present embodiment provides a kind of city rail vehicle promptly to rise the electronic air supply device of bow, is placed in the liter bow cabinet of city rail vehicle guest room, and the discharge pipe of device rises the bow pipeline with city rail vehicle and links to each other to a liter bow pipeline air feed.Referring to Fig. 2, to be 40L/min, the motor-driven power nothing oil motor driven compressor 3 that is not more than 200KW, pressure switch 4, relay 5, check valve 6, safety valve 7 by connecting line and electric wiring integrate the specified free air capacity of Jiang Yitai forms described city rail vehicle and promptly rise the electronic air supply device of bow.Check valve 6 is installed in the air outlet place of no oily motor driven compressor 3, and safety valve 7 is connected on the connecting line.The control power supply of whole device and the power supply that does not have an oily motor driven compressor 3 are provided by city rail vehicle, and circuit is connected with the circuit of city rail vehicle by electric connection.
Referring to Fig. 3, being used for the step that city rail vehicle promptly rises the air feed automatic guidance implementation method of bow is, described pressure switch 4 is according to system's blast action, when pressure is lower than specified value, the pressure switch contact closure, cutin relay 5 control power supplys, relay 5 closings of contact do not have the motor power supply conducting of oily motor driven compressor 3, drive no oily motor driven compressor 3 runnings and beat wind, when pressure reaches certain value, pressure switch 4 contact open relay powers, relay 5 contact opens disconnect the motor power supply of no oily motor driven compressor 3, do not have oily motor driven compressor 3 and stop to beat wind automatically, thereby realize rising the automatic guidance of bow system air feed pressure.
Above-mentioned be used for city rail vehicle promptly rise the bow electronic air supply device major part function as follows:
