Embodiment 1

[0054] An embodiment of the present invention discloses a durability test device for a hydrogen circulating pump, such as figure 1 As shown, it includes a controller and an air intake structure, a pressure selection unit, a multi-channel test unit, and an air outlet structure connected in sequence.

[0055] Each channel in the multi-channel test unit is independent and parallel to each other, and each channel is provided with a hydrogen circulating pump to be tested (the durability test of the hydrogen circulating pump to be tested can be performed independently) and a hydrogen circulating pump to be tested. It is a control device for regulating the flow and pressure of the input gas of the hydrogen circulating pump to be tested.

[0056] The inlet structure is used to input gas such as hydrogen or a substitute gas for hydrogen.

[0057] The pressure selection unit is used to output the gas of the set pressure according to the control of the controller.

[0058] Outlet struc...

Embodiment 2

[0062] Improvements are made on the basis of the device described in Example 1, and the shapes of the air inlet structure and the air outlet structure are both trumpet-shaped. Among them, the inner diameter of the intake end of the intake structure should be larger than the inner diameter of the exhaust end, the intake end is set to face upward, the inner diameter of the intake end of the outlet end of the air outlet structure is smaller than the inner diameter of the exhaust end, and the exhaust end is set to face the test device. side.

[0063] Preferably, the control equipment on each channel of the multi-channel test unit includes a shut-off valve, a flow stabilizer such as Figure 2~3 shown. Wherein, after the stop valve and the flow regulator are connected end to end in sequence, they are connected to the inlet end of the hydrogen circulating pump to be tested in the channel.

[0064] The output end of the controller is respectively connected with the control ends of a...

Abstract

The invention provides a durability testing device for a hydrogen circulating pump, belongs to the technical field of fuel cell engines, and solves the problem that the durability of the hydrogen circulating pump cannot be verified in the prior art. The device comprises a gas inlet structure, a pressure selection unit for outputting normal-pressure gas or high-pressure gas, a multi-channel test unit for testing the durability of the hydrogen circulating pump to be tested through the normal-pressure gas or the high-pressure gas, and a gas outlet structure which are connected in sequence. Wherein the channels of the multi-channel test unit are mutually independent and are connected in parallel, and each channel is provided with a to-be-tested hydrogen circulating pump and regulation and control equipment for regulating and controlling the flow and the pressure of input gas of the to-be-tested hydrogen circulating pump. The device is used for testing the hydrogen circulating pump, the durability verification time is greatly shortened, meanwhile, the whole fuel cell engine does not need to be subjected to verification and real vehicle carrying verification, the development cost is effectively saved, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of fuel cell engines, in particular to a durability testing device for a hydrogen circulating pump. Background technique [0002] Fuel cell engine is a device that produces water while electrochemically reacting with hydrogen and oxygen. It has the advantages of high power generation efficiency, low environmental pollution, high specific energy, low noise, etc. The field has more good application prospects. [0003] As the core component of the fuel cell engine, the durability of the hydrogen circulation pump directly determines the performance of the fuel cell engine. At present, there is no test device for the durability verification of the hydrogen circulating pump, and it is an urgent problem to be solved in the development of the fuel cell engine industry to propose a test device specially designed to verify the durability of the hydrogen circulating pump. SUMMARY OF THE INVENTION [0004] In view o...
