Description

Technical Field

[0001] This utility model relates to the field of hydrogen equipment testing technology, and in particular to an automatic testing platform for hydrogen equipment. Background Technology

[0002] Currently, after the completion of hydrogen equipment, it is generally necessary to perform pressure tests on the internal pipelines and overall operational tests, such as... Figure 2 As shown, pipeline pressure testing uses pipeline system 101 to increase the test pressure of the test gas (e.g., nitrogen, helium) to the test pressure via a booster pump. After completion, the gas is directly vented through the pipeline system. Operation testing, on the other hand, requires pressurizing the test gas (e.g., nitrogen, helium, hydrogen) or directly introducing it into the equipment through pipeline systems 101 and 102 to simulate actual operating conditions. After completion, the test gas is directly vented through pipeline system 103. Existing testing platforms directly vent the test gas or pressure testing gas, which leads to waste of these gases and increases testing costs. Utility Model Content

Detailed Implementation

[0015] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0016] An automated testing platform for hydrogen equipment, reference Figure 1 The system includes a gas source device 1, a booster pump 6, a compressed air device 10, a testing device 11, and a piping system. The piping system connects the pipes of each component. The gas source device 1 provides inert gas for testing and is connected to the booster pump 6, which in turn is connected to the testing device 11. In this embodiment, there are two testing devices 11. In other embodiments, there may be one, three, or more. The outlet of the testing device 11 is connected to a vent pipe and a first recovery pipe. The first recovery pipe is then connected to the booster pump 6. A second recovery pipe is then provided between the booster pump 6 and the gas source device 1. The first and second recovery pipes are used to detect the recovery of gas. The compressed air device 10 is connected to the booster pump 6 and the testing device 11 and is used to provide compressed gas for the booster pump 6 to operate normally. It is also used to provide instrument air to the testing device 11.

[0017] The above-mentioned testing system can realize pressure testing, operation testing, and gas recovery. Specifically, for pressure testing and operation testing, the working process is as follows: the gas source device 1 outputs test gas, the gas is increased to the test pressure by the booster pump 6, and then the gas enters the test equipment 11 through the pipeline for pressure testing and testing. For gas recovery, after the pressure testing or operation testing is completed, the test gas enters the booster pump 6 through the first recovery pipeline, and then flows into the gas source device 1 for recovery through the booster pump 6. If the gas in the test equipment 11 does not need to be recovered, it can be vented through the vent pipe.

[0018] To facilitate control, multiple control valves are installed in the pipeline. A first control valve 4 is installed at the outlet of the air source device 1, a second control valve and a third control valve are installed at the inlet and outlet of the booster pump 6, a fourth control valve 8 is installed at the inlet of the test equipment 11, and a fifth control valve 13 is installed on the vent pipe. A sixth control valve and a seventh control valve are respectively connected to the port where the compressed air device 10 is connected to the booster pump 6 and the port where it is connected to the test equipment 11. By setting up control valves, the on / off state of the pipeline can be controlled, which facilitates the control of the test platform.

[0019] In this embodiment, two testing devices 11 are provided, and therefore a fourth control valve 8 is provided at the inlet of both testing devices 11.

[0020] Furthermore, the first recovery pipeline is connected to an eighth control valve 14 at the end near the test equipment 11, and the second recovery pipeline is equipped with a ninth control valve 7 and a check valve 5. During pressure testing or operational testing, closing the eighth control valve 14 and the ninth control valve 7, combined with the check valve 5, can prevent test gas from entering the recovery pipeline.

[0021] refer to Figure 1 The specific working process of the test platform by operating the above control valves is as follows: During pressure testing and operation testing, the eighth control valve 14 and the ninth control valve 7 are closed, and the first control valve 4, the second control valve, the third control valve, the fourth control valve 8, the sixth control valve, and the seventh control valve are opened. The gas source device 1 outputs test gas, which is increased to the test pressure by the booster pump 6. Then, the gas enters the test equipment 11 through the pipeline for pressure testing or operation testing. After the test is completed, if it is necessary to recover the test gas, the first control valve 4 and the fourth control valve 8 are closed, and the eighth control valve 14 and the ninth control valve 7 are opened. The test gas in the test equipment 11 enters the booster pump 6 through the first recovery pipeline, and after exiting the booster pump 6, it enters the gas source device 1 through the second recovery pipeline to complete the recovery of the test gas. If it is not necessary to recover the test gas, the fifth control valve 13 is opened directly, and the test gas is released through the vent pipe.

[0022] To prevent excessive pressure when high-pressure gas enters the gas source device 1, a pressure reducing valve 15 is installed on the first recovery pipeline. After the test gas comes out of the test device 11, it enters the first recovery pipeline. After passing through the pressure reducing valve 15, the pressure of the test gas will be reduced to a safe pressure that allows it to enter the gas source device 1. Then, it passes through the booster pump 6 and the ninth control valve 7 before entering the gas source device 1. When the test gas pressure is high but still within the acceptable safe pressure range of the gas source device 1, the booster pump 6 can be left unstarted, and the test gas can flow directly through the booster pump 6 before entering the gas source device 1. When the test gas pressure is lower than the gas source pressure in the gas source device 1, the booster pump 6 is started to pressurize the test gas and send it into the gas source device 1.

[0023] In this embodiment, the first control valve 4, the second control valve, the third control valve, the fourth control valve 8, the fifth control valve 13, the sixth control valve, the seventh control valve, the eighth control valve 14, and the ninth control valve 7 are pneumatic valves, which are supplied with normal operating gas by the compressed air device 10.

[0024] Pressure transmitters 3 are installed at the outlet of the gas source device 1, the outlet of the first control valve 4, the outlet of the booster pump 6, and the inlet and outlet of the test equipment 11. These transmitters can monitor the gas pressure at different locations and interlock the corresponding control valves (pneumatic valves) to automatically control the gas to complete the pressure test or test process. When the gas pressure exceeds the normal pressure, the control system will issue an alarm and close the corresponding interlocked control valve.

[0025] Safety valves 2 are connected to the outlet of the gas source device 1 and the inlet of the test equipment 11. When the gas entering the gas source device 1 and each test equipment 11 is over-pressurized, the safety valves 2 will open to release pressure and protect the safety of the test platform.

[0026] The test platform in this embodiment is also equipped with a PLC control system, which is used to control the air source device 1, booster pump 6, compressed air device 10, test equipment 11 and various valves to realize automatic control of the entire test process.

[0027] This embodiment can perform comprehensive testing and inspection of hydrogenation equipment, simulate the testing environment for equipment performance, test multiple devices simultaneously, and recycle the test gas. The entire testing process is automatically controlled by the system. Compared with previous equipment testing processes, it improves testing efficiency, saves costs, and reduces the safety risks to operators while ensuring equipment quality.

[0028] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
