Problems solved by technology
Therefore, a large number of ice crystal particles are often precipitated in the fuel during the test, and these ice crystal particles will generally block the fuel filter of the tester leading to the fuel supply pipeline of the test piece, causing the flow of fuel to be blocked, the flow rate to drop, and even the pipeline to be blocked, etc. phenomenon, effect test
[0005] Affected by ice crystal blockage, traditional testers generally only last for a short period of time under high flow conditions, and cannot guarantee the time to meet the test requirements, which will affect the confidence of the test results

The invention provides an oil supply pipeline system. The oil supply pipeline system comprises a plurality of oil supply pipelines and a control module, wherein the plurality of oil supply pipelines are connected between the oil supply end and the oil using end in parallel, and the control module is used for controlling on and off of each of the oil supply pipelines; each of the oil supply pipelines comprises a fuel filter and a heater; when the oil supply pipes are controlled to be switched on, the fuel filters arranged on the oil supply pipelines can be frozen along with the time; the control module is continuously switched between the plurality of oil supply pipelines so as to control one of the oil supply pipelines to be switched on to supply oil, in response to switching tothe next oil supply pipeline to supply the oil, and the heater arranged on the previous oil supply pipeline which is switched on is controlled to heat the corresponding fuel filter so as to achieve deicing.
Description
technical field [0001] The invention relates to an oil supply pipeline system, in particular to an oil supply pipeline system used for low-temperature operation to prevent the filter from freezing and blocking. Background technique [0002] With the development of technology, the thrust of modern aero-engines is getting bigger and stronger, and the adaptability to the environment is getting stronger and stronger, which means that the performance requirements of each component of the engine are higher and the reliability is more reliable. In order to ensure that the reliability of the engine and various accessories meets the requirements, the US FAA has proposed relevant airworthiness certification standards. In my country, the China Civil Aviation Airworthiness Certification Center refers to the FAA standard and proposes CCAR33, an airworthiness certification standard suitable for my country's civil aircraft. [0003] According to the requirements of engine fuel icing and s...
