Embodiment 1

[0123] Such as Figure 4-Figure 8As shown, the equipment 100 may include: equipment oil tank 11, main pipeline 21, flushing exhaust pipeline 31, external refueling pipeline 41, internal refueling pipeline 51, switching pipeline 61, detection pipeline 71, external oil inlet pipeline 27. The oil discharge pipeline 28 is connected externally. The main pipeline 21 includes: an oil inlet pipeline section 211 , a preset pipeline section 212 and a detection pipeline section 213 arranged in sequence along the oil flow direction. A first upstream filter 2411 and a second upstream filter 2412 are provided between the oil inlet pipeline section 211 and the preset pipeline section 212, a pressure gauge 25 is provided between the preset pipeline section 212 and the detection pipeline section 213, and the detection pipeline section 213 A downstream filter 242 is provided downstream of . The equipment oil tank 11 has a temperature sensor 13 , an air filter 12 , a liquid level gauge 14 and ...

Embodiment 2

[0144] Such as Figure 9-Figure 13 As shown, compared with the first embodiment above, the second embodiment has the same general structure, and the same components use the same reference numerals. The differences mainly include: (1) The oil pump device 26 includes an oil pump 261 and an electric motor 262. Then there is a double pump, so that the external oil inlet pipeline 27 connected in parallel with the oil inlet pipeline section 211, and the external oil discharge pipeline 28 and the control device 29 related to the external oil inlet pipeline 27 can be omitted. (2) The switch device 62 is a manually adjusted direction control cock, and the switch device 53 and the second oil suction filter 52 are canceled on the internal fuel oil pipeline 51 . (3) The first oil suction filter 63 on the switch line 61 is eliminated, and the third oil suction filter 216 is provided between the inlet port 21 a of the main line 21 and the oil pump 261 . In contrast, the structure of the se...

Embodiment 3

[0161] Such as Figure 14-Figure 18 As shown, compared with the above-mentioned embodiment 2, the third embodiment has the same general structure, and the same components use the same reference numerals. The differences mainly include: (1) the inlet port 21a and the oil pump 261 arranged on the main pipeline 21 are omitted Between the third oil suction filter 216. (2) There is only one upstream filter 241 . (3) The external refueling pipeline 41 is canceled, and the flushing exhaust pipeline 31 is a multifunctional pipeline 31A that can be installed with a refueling gun 34, so that the multifunctional pipeline 31A can be used for flushing, exhaust, and refueling of the vehicle hydraulic braking system . (4) Cancel the first overflow valve 43, set the second overflow valve 44 on the multifunctional pipeline 31A, set the third overflow valve 45 on the preset pipeline section 212, and set the preset position on the main pipeline 21 One-way valve 217 upstream of line section 21...

Abstract

The invention discloses equipment for processing a vehicle hydraulic braking system. The equipment comprises an equipment oil tank, a main pipeline, a detection pipeline, a dirt detection device and afirst protection device, wherein an inlet end and an outlet end of the main pipeline are communicated with the equipment oil tank, and the detection pipeline is connected with a detection pipeline section on the main pipeline in parallel; the dirt detection device is arranged on the detection pipeline, and the first protection device is arranged on the detection pipeline and used for controllingopening and closing of the detection pipeline. According to the equipment for treating the vehicle hydraulic braking system, by arranging the first protection device, the dirt detection device can work only when needed, and the service life of the dirt detection device is prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a device for processing a hydraulic braking system of a vehicle. Background technique [0002] Rail vehicles are equipped with a hydraulic braking system. During the production process of rail vehicles, impurities such as burrs will inevitably remain in the pipelines of the hydraulic braking system. Therefore, before the rail vehicles leave the factory, the pipelines of the hydraulic braking system need to be cleaned to avoid During the operation of the rail vehicle, it is affected by the impurities in the pipeline of the hydraulic brake system, which causes the operation failure of the rail vehicle. There are devices for flushing the pipelines of the hydraulic braking system of rail vehicles in the related art. However, these devices are not perfect and need to be improved. higher cost. Contents of the invention [0003] The present invention aims to solve at least one of t...
