Abstract
A vacuum brake single vehicle tester for railway vehicles is characterized by comprising a vacuum pump, a main pipeline, two vacuum pressure gauges, an air dust filter and a vacuum hose, wherein the vacuum pump via the main pipeline is serially connected with a vacuum pressure meter, a ball valve for cutting off the line to keep pressure, another vacuum pressure meter, the air dust filter, a brake ball valve and the vacuum host. The utility model can test the performances of a vacuum brake vehicle, as the leakage amount test, the brake test, the release test and the vacuum degrees of a vacuum brake system, thereby finding the reliability, stability and availability of the vacuum brake vehicle.
Description
Technical field
The utility model relates to all passenger train vacuum braking single car testing devices that adopt vacuum braking system.
Background technology
At present, all adopt air brake on the passenger train of China, do not equip the vehicle of vacuum brake equipment, have only the Asia, non-, draw many countries still to adopt the vehicle of vacuum braking system.The vehicle of against vacuum brake system need be determined reliability, stability and the availability of its function.Yet also do not have to determine the device of its functional reliability, stability and availability at present, therefore research and develop rolling stock and be imminent with the vacuum braking single car testing device.
The utility model content
Technical problem to be solved in the utility model is a kind of vacuum braking single car testing device of exploitation, be used to install the vehicle of vacuum braking system, carry out fall debugging behind the car of brake system, whether the parameters of check vacuum braking system adheres to specification, thereby determines reliability, stability and the availability of its function.
For solving the problems of the technologies described above, the utility model provides a kind of rail truck vacuum braking single car testing device, it is characterized in that: comprise that vacuum pump, main line, two pressure vacuum gauges, air consider dirt device, vacuum hose, vacuum pump by main line connect pressure vacuum gauge successively, the ball valve, another pressure vacuum gauge, the air that are used to block pressurize considered the dirt device, braking is with ball valve, vacuum hose.
The utility model can be made test to the various aspects of performance of vacuum braked stock, comprise: data such as the amount of leakage test of vacuum braking system, brake test, alleviation test and energy measurement vacuum tightness, thereby reliability, stability and the availability of definite vacuum braked stock function.
Description of drawings
Accompanying drawing is a structure principle chart of the present utility model.
Embodiment
With reference to accompanying drawing, the utility model comprises vacuum pump 1, connects 2 inches main lines 8 of each equipment, 1/2 inch steel pipe 9 of the pressure vacuum gauge 2 of measurement of vacuum and 3 usefulness links to each other with main line, the 1 inch ball valve 4 that is used to block pressurize places main line, air on the main line is considered dirt device 5 can filter out intrasystem impurity, braking links to each other with main line with 1/2 inch ball valve, 6 usefulness steel pipes 9, and total system links to each other with vehicle by 2 inches vacuum hoses 7.
When using the utility model, earlier vacuum hose is linked to each other with wanting tested vehicle, open ball valve 4 again, close ball valve 6, start vacuum pump, when pressure vacuum gauge 2 and pressure vacuum gauge 3 reach the pressure that will test, close ball valve 4, can carry out the pressurize test then; Open ball valve 6 and just can carry out brake test; After the car brakeing, close ball valve 6, open ball valve 4, can observe and alleviate test.
