Problems solved by technology
At present, neither the national standard nor the machinery industry standard stipulates the dynamic test requirements for high-pressure oil pipes.
Usually, OEMs can only test the performance of high-pressure oil pipes by means of type tests after installation to see if they can meet the requirements for use.
If there are different schemes for high-pressure oil pipes, all of them need to be verified by type test, which will undoubtedly be a huge waste of manpower and material resources

The invention relates to a high-pressure oil pipe state test system. The system comprises a vibration test control subsystem, a high-pressure fuel oil control subsystem connected and matched with the vibration test control subsystem and a fuel oil supply subsystem connected with the high-pressure fuel oil control subsystem, wherein the vibration test control subsystem and the high-pressure fuel oil control subsystem are electrically connected with an engine controller ECU; the vibration test control subsystem comprises a vibration test platform, a support frame arranged at the right part of the middle part of the vibration test platform, a vibration limiting device arranged at an upper end of the support frame and a vibration sensor; the controller is connected with the vibration sensor through a first connecting line, and the controller is connected with the vibration test platform through a second connecting line; the controller is electrically connected with the engine controller ECU through a third connecting line. The system is advantaged in that the high-pressure oil pipe can be dynamically tested by simulating the actual working condition of an engine, and reliability of the high-pressure oil pipe is tested.
Description
Technical field [0001] The present invention relates to an engine fuel system, and more particularly to a high pressure oil tube state test system. Background technique [0002] Under the increasingly stringent environmental requirements, high-power diesel engines can only carry out technical innovations, using a common rail fuel system to meet the requirements. The co-rail fuel system is mainly to increase the effect of injection pressure and flexibility to achieve the effect of optimizing combustion, reducing emissions. Increasing the injection pressure is also a test for the fuel system, the high pressure tube is the first to rush. At present, national standards and mechanical industry standards have not specified to perform dynamic test requirements for high pressure tubes. And usually the host plant can only perform performance testing of high pressure tubes in a model trial, see if the usage requirement can be met. If there are different programs in different programs, it i...
