How To Ensure the Accuracy of High Pressure Common Rail Test Bench

The 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.

The 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 degree deviation.

In 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.

Matters 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.
