Problems solved by technology

Therefore, in the development stage of the SCR urea injection system, it is necessary to carry out a lot of experimental work such as performance testing, precision testing, durability assessment, and optimization calibration. These tasks are initially carried out when the engine is running, which consumes a lot of manpower and material resources. , and the resulting emissions are harmful to the environment

Embodiment Construction

[0058] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0059] An off-line multi-station general-purpose SCR system durability test device includes five parts: SCR system, liquid supply device, spray device, compressed air supply system, power supply and measurement and control system.

[0060] SCR system: ten sets of SCR systems can be installed on this test bench, and each urea pump 8 installation stations can be equipped with mounting plates corresponding to different urea pumps, which are connected to the movable plate on the bench through bolts, and the movable plate can be rotated by a loose leaf, which is convenient Plug and unplug the liquid inlet pipe, liquid return pipe, injection pipe and air pipe on the urea pump. Therefore, the test bench can be used for free combination testing of different types of urea pumps. Each nozzle installation station is connected to the visual nozzle through the corre...

Abstract

The invention discloses an offline multi-station universal SCR system endurance test device and method. The device does not depend on an engine rack, ten SCR system stations are arranged, the device is applicable to SCR urea injection systems of a gas-assisted urea pump type and a non-gas-assisted urea pump type, steady-state testing, self-defined transient-state testing and endurable cyclic testing can be achieved, and meanwhile simulation on the liquid filling, pressure building, injecting, blowing and stopping process of an SCR system can be achieved. A large quantity of manpower and material resources consumed during engine rack testing can be avoided, injected urea is collected through an acrylic tube and a transverse liquid collecting tube and flows back to a vertical liquid collecting pipe again, and therefore it can be avoided that urea is directly discharged to atmosphere, environmental pollution is avoided, urea can be reused, resources are saved, and test cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical performance testing, in particular to an off-line multi-station universal SCR system endurance test device. Background technique [0002] Diesel engine has high thermal efficiency, low fuel consumption and CO2 emission, and its proportion in vehicle power is increasing year by year. At the same time, particulate matter (PM) and nitrogen oxides (NOx) have become the main harmful substances in diesel engine emissions. According to the National IV and National V emission regulations of heavy-duty diesel vehicles, reducing PM emissions from inside the engine and converting NOx emissions from outside the engine is a technical route that is in line with China's national conditions and has sustainable development. Selective Catalytic Reduction (SCR) technology is currently one of the most effective post-treatment technologies for reducing NOx emissions from diesel engines. Using SCR technology can ma...
