How To Ensure the Accuracy of High Pressure Common Rail Test Bench
inertia of the flywheel selected for different types of high power common rail
test benches of different powers should be different. We have conducted
rigorous calculations and experiments on model and power. The final
determination of the inertia of the flywheel is very scientific and practical,
and each flywheel has been subjected to dynamic balance and static balance
experiments prior to installation, thus ensuring more effective testing.
last thing to be determined in the transmission system of the high pressure
common rail test bench is the oil pump coupling. The standard of the
International Standards Organization recommends that the rigidity of the test bench
drive coupling must be sufficient to prevent any resonance state from
occurring, and the fuel injection on the test bench, and at the same time the
maximum allowable load value should not cause the total drive to exceed 0.14
the design of the high pressure common rail test bench coupling, there is a
very important requirement, that is, the coupling can withstand the impact of
the rear impact, if it cannot, it will affect the oil supply of the tested fuel
injection pump. Couplings designed by us can meet the above requirements and
can also compensate for the high center error of the test bench due to
long-term use, ensuring the accuracy of the test bench. When the above
requirements are met, a complete high-pressure fuel pump test bench drive
system is designed.
needing attention in using。
First, we must be fully prepared for the experiment. Familiar with the experimental content and master the experimental steps. When performing experiments, please strictly follow the experimental procedures to prevent fire caused by non-standard operation. Strictly observe laboratory discipline, prohibit playing in the laboratory, playing farce, and prevent fires caused by equipment rupture. It is forbidden to use laboratory equipment and medicines that are not related to the experiment, especially electric heating equipment.
It is strictly forbidden for people, especially children, to enter the laboratory to prevent fires caused by illegal activities of unrelated personnel. It is forbidden to live in the laboratory, and it is even more important to not use domestic fires in or near the laboratory. In particular, it is not allowed to use open flames, and it is even more difficult to burn fireworks and firecrackers to prevent fires in combustibles and other flammable materials inside the pilot. Attention to the proper use and storage of the electric heating apparatus of the high pressure common rail test bench, the electric appliances being used are not allowed to approach the combustibles.
