Description
Technical field
The invention belongs to railway transport fields, and in particular to a kind of air compressor machine work ratio for rail vehicle braking system
Automatic regulating apparatus and control method.
Background technique
City railway vehicle and Braking System for Multiple Units generally use oil lubrication air compressor (piston type or spiral shell at present
Rod-type), initial stage is opened in new line, since passenger capacity is insufficient, line clear is shorter or the low situation of the online rate of vehicle, will lead to
There is emulsification of lubricant problem in the case where low work ratio in oil lubrication air compressor machine, and serious emulsification would potentially result in sky for a long time
There is catastrophe failure and disabler in press.Current common solution is when there is emulsification of lubricant situation by artificial
It persistently beats wind and temporarily eliminates emulsification situation, but when this scheme is remedial measure after going wrong and needs to expend a large amount of
Between and manpower.Another method is to reduce the capacity of air compressor machine, but such method can be led in the larger situation of air feed demand
It is insufficient to cause air feed, and changes the design parameter of air compressor machine.
Summary of the invention
It is automatic the technical problem to be solved by the present invention is to design a kind of air compressor machine work ratio of rail vehicle braking system
Device and control method are adjusted, there can be the work ratio state of control host real time monitoring air compressor machine, when judging at air compressor machine
Then pass through control adjustment device automatic adjustment air compressor machine work ratio in the lower situation of long period work ratio and is in zone of reasonableness.
In order to solve the above technical problems, the present invention provides a kind of railway car primary air compressor machine work ratio automatic regulating apparatus,
It is characterized by comprising cutout cock, test point, pressure sensor, solenoid valve, throttle valve, control host, cutout cock entrances
Train braking system blast main is connected, cutout cock outlet is separately connected test point and solenoid valve input, and wherein test point connects
One output end of pressure sensor, pressure sensor and solenoid valve is connect with control host by electrical rigid line, and host is controlled
For reading pressure sensor information, while electromagnetism valve events are controlled, the another output of solenoid valve connects throttle valve.
The throttle valve output end connects a muffler.
A kind of railway car primary air compressor machine work ratio adjust automatically control method, it is characterised in that: by connecting blast main
Pressure sensor or network connection train control system provide air compressor machine operating state data, control Framework computing go out work as
The work ratio situation of preceding train air compressor machine, when work ratio is lower than setting value, triggering solenoid valve discharges blast main pressure,
And implement to calculate air compressor machine work ratio, so that air compressor machine work ratio reaches suitable conditions.
A kind of air compressor machine work ratio automatic regulating apparatus of the present invention can monitor pneumatics in real time by control host
The work ratio state of machine, when judging that air compressor machine long period work ratio is low, control host automatically adjusts air compressor machine work ratio
In zone of reasonableness, do not need manually to participate in not needing transformation air compressor machine itself, control method is simple yet.
Detailed description of the invention
Fig. 1 is the specific embodiment schematic diagram of air compressor machine work ratio automatic regulating apparatus of the present invention.
Specific embodiment
Referring to Fig.1, air compressor machine work ratio automatic regulating apparatus of the invention is passed by cutout cock 01, test point 02, pressure
Sensor 03, solenoid valve 04, throttle valve 05, muffler 06, control host 07 form.Wherein 01 entrance of cutout cock connects railcar
The blast main of braking system, cutout cock outlet are separately connected test point 02 and solenoid valve 04, wherein the connection of test point 02 pressure
Force snesor 03, pressure sensor 03 acquire the pressure of blast main and pressure information are sent to control host 07, solenoid valve 04
It is controlled by control host 07.Solenoid valve 04 connects throttle valve 05,05 joint noise reduction device 06 of throttle valve.Control host 07 can lead to simultaneously
Network connection train control system is crossed, air compressor machine operating state data is obtained.
When rail vehicle operation, control host 07 obtains blast main pressure data by pressure sensor 03, and can
The air compressor machine operating state data from train control system is received by network.Host 07 is controlled to analyze simultaneously by above-mentioned data
The current work ratio of main air compressor machine is calculated, if calculating work ratio is lower than target value, control host 07 controls solenoid valve 04 and holds
The continuous or stage obtain it is electric so that compressed air is discharged into atmosphere by throttle valve 05 and muffler 06 in blast main, solenoid valve 04
The Calculation results that the electric time is obtained according to the practical consumption landscape condition of rail vehicle and control host 07 are determining, suitably to increase sky
Gas consumption improves the work ratio of main air compressor machine to OK range.
