Locomotive electro-pneumatic valve detection test bench

Abstract

The invention provides a locomotive electro-pneumatic valve detection test bench, comprising a system test rack, a pneumatic component cabinet and an electrically controlled operating table; the electrically controlled operating table is provided with an indicator light concentration area, a current-voltage display concentration area, a pressure display concentration area, a rotary adjusting switch concentration area and an input / output concentration area sequentially from top bottom; different indicator lights in different colors may be used to display current operating state of the test bench, with more visual expression and higher practicality; in case of weak light, technicians may observe accurately and read pressure, voltage, and current values through a digital luminous display, and the probability of mistaken readings is decreased; in case of different pressure, voltage and current values, the luminous display displays different background colors, technicians may be timely reminded of current measurements, and significant warning effect is achieved.

Description

technical field [0001] The invention relates to a detection test bench, in particular to a detection test bench for a locomotive electropneumatic valve, and belongs to the technical field of detection devices for a locomotive electropneumatic valve. Background technique [0002] The test bench of the locomotive electropneumatic valve is an instrument and equipment used to detect whether the locomotive electropneumatic valve is working normally. It is used for diagnosis and technical inspection before the installation of the locomotive electropneumatic valve and during the manufacture and repair of the locomotive electropneumatic valve. The test bench of the locomotive electropneumatic valve can check the performance and parameters of the locomotive electropneumatic valve, determine the technical status of the locomotive electropneumatic valve, detect the air tightness and performance of the locomotive electropneumatic valve, and improve the stability of the locomotive electro...

AI Technical Summary

Problems solved by technology

[0003] In the prior art test bench for electro-pneumatic valves for locomotives, each part of the display mainly displays values ​​through pointers. It is difficult to read and observe the values, and sometimes there will be some reading errors. It is difficult for technicians to see the value clearly, and it is very difficult to read the voltage value, which makes the technician's observation blind, and there is no suitable voltage value display, which is likely to cause misreading. and operability are not high, need to be tested separately, increase the workload of technicians, and use is also more complicated at the same time, it is not convenient for technicians to operate, so it is very important for the improvement of the test bench of locomotive electropneumatic valve, and it needs to be further developed Complete

[0004] On the whole, there are mainly the following defects in the detection test bench of the locomotive electropneumatic valve in the prior art: one is that the design of the indicator lights and display equipment is not scientific enough, and the current pressure state cannot be simply and intuitively explained, the data is not intuitive enough, and the detection The operation is complicated, which increases the workload of technicians, is not suitable for locomotive maintenance needs, and is not practical; second, the current voltage and resistance measurements use pointers to display values. The accuracy of the numerical value is not high, which will cause some numerical errors; the third is that the display of the test bench of the locomotive electro-pneumatic valve does not use a background light-emitting display panel, and the existing display is difficult for technicians to see when the light is relatively dark. Clearing the voltage value is prone to reading blind spots, and the correct value cannot be read, which may cause misreading
