Embodiment 1

[0033] Such as figure 1 As shown, this embodiment provides a fuel cell test system pipeline airtightness pressure-holding test platform, including a base 1, the base 1 is a cylindrical structure with a hollow rectangular cross-section that penetrates up and down and is closed on the sides surrounded by four plates. . The four boards can be made of aluminum or wood, the aluminum can be fixed by welding, and the wood can be fixed by hinges or mortise and tenon structures. The upper surface of the base 1 can be covered with a layer of panels. In order to make the test platform light and easy to manufacture, the present embodiment adopts a structure that penetrates up and down.

[0034] On the base 1 are fixed a first bracket 2, a second bracket 3, a third bracket 4, a front air intake pipeline 5, and a rear exhaust pipeline 6; The air pipeline 5 and the rear exhaust pipeline 6 are respectively fixed on the second support 3 and the third support 4, and the pipeline 7 to be teste...

Embodiment 2

[0050] Such as Figure 5 As shown, in this embodiment, on the basis of Embodiment 1, the power supply 9 is fixed on the second support 3 or the third support 4, so as to facilitate the overall movement of the test platform. The power supply 9 in this embodiment is a DC24V power supply 9 with an input of 220V and an output of 24V. If it is fixed on the outer side, the outer side of the pole 31 needs to be provided with a vertical chute 311, the power supply 9 is provided with a skirt, and the skirt is provided with a screw hole, and the bolt 81 passes through the screw hole of the power supply 9 and the limit The nut 82 in the vertical slide groove 311 outside the vertical bar is screwed and fixed. If it is fixed on the top surface, it is necessary to connect a plurality of upright bars 31 by another cross bar 32, and then fix the power supply 9 and the cross bar 32 by the same method.

Abstract

The invention provides a fuel cell test system pipeline air tightness pressure maintaining test platform. The platform comprises a base, a front-end air inlet pipeline and a rear-end air outlet pipeline, a to-be-tested pipeline is fixed on a first support, and the front-end air inlet pipeline and the rear-end air outlet pipeline are respectively fixed on a second support and a third support. The to-be-tested pipeline is respectively communicated with the front-end air inlet pipeline and the rear-end air outlet pipeline, a first ball valve and a first pressure gauge are respectively fixed on the front-end gas inlet pipeline according to a gas flow direction, and a second pressure gauge and a second ball valve are respectively fixed on the rear-end exhaust pipeline according to the gas flowdirection. Three supports are built on the base, the front-end air inlet pipeline and the rear-end air outlet pipeline are fixed, and a fixing support is provided for the to-be-tested pipeline, so that the rapid assembly and disassembly are facilitated, and a testing platform is provided for testing. The testing results can be monitored in real time through the ball valves and the pressure gaugesarranged on the front-end air inlet pipeline and the rear-end air outlet pipeline, and the testing results are accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of fuel cell detection, in particular to a fuel cell test system piping airtightness pressure-holding test platform. Background technique [0002] In the existing national standard fuel cell engine performance test, there is a test about the air tightness test of the fuel cell engine. Whether there is damage or leakage, so the test system will be equipped with a hydrogen pipeline leading to the fuel cell to be tested. In order to ensure the airtightness of the fuel cell engine internal stack as a whole, the data accuracy and Reliability, so it is necessary to pre-pressurize the internal pipeline of the test system to ensure that there is no leakage in the pipeline, so as to meet the needs of the engine air-tightness pressure-holding test. [0003] In the prior art, the test method for the pipeline is that the pipeline under test is directly connected to the gas cylinder, the end of the pipeline is closed, a...
