Problems solved by technology

The hydrogen source used in this patent is compressed air, the composition of which is quite different from that of hydrogen, and the quality and flow resistance cannot effectively simulate the operating environment of a hydrogen circulation pump. The test results are not accurate, and it is more suitable for air compressor device testing. pulse conditioning

Abstract

The invention discloses a hydrogen circulating pump test system for a fuel cell engine and a test method thereof.The test system comprises a circulating pump, an inlet of the circulating pump is connected with a hydrogen source through a first pipeline, and a proportional valve, a first three-way valve and a temperature control heat exchange assembly are sequentially arranged on the first pipeline in the flow direction; a first pressure sensor, a first temperature sensor and a humidity sensor are arranged on the first pipeline at the downstream position of the temperature control heat exchange assembly, and a second temperature sensor, a second pressure sensor, a second three-way valve and a throttling valve are arranged on the second pipeline between an outlet of the circulating pump and the first three-way valve. The second temperature sensor and the second pressure sensor are located on the upstream of the second three-way valve and the throttling valve, and the second three-way valve is connected with the pressure release valve through a third pipeline. According to the test system, the circulating pump can completely simulate the running state environment of the fuel cell engine, and whether the hydrogen circulating pump for the fuel cell engine can meet the use conditions or not is evaluated under the condition of completely simulating the temperature, pressure and humidity environment conditions.

Description

technical field [0001] The invention belongs to the technical field of hydrogen circulation pump testing, and in particular relates to a hydrogen circulation pump testing system for a fuel cell engine and a testing method thereof. Background technique [0002] In the actual application scenario of the hydrogen circulation pump for fuel cell engine, the inlet rated flow rate, inlet temperature, inlet pressure, outlet temperature and outlet pressure of the circulation pump need to be monitored. Whether the circulation pump can meet the application scenario of the fuel cell engine system needs to be monitored. To carry out preliminary verification, based on this, it is necessary to develop a hydrogen circulation pump test system for fuel cell engines. [0003] Chinese patent CN112392711A discloses a test method and device for a hydrogen circulation pump. The test method includes: obtaining environmental parameters and test parameters corresponding to each working condition; whe...
