Le testeur de cokéfaction en phase gazeuse VPC est conforme aux exigences des normes d'essai, notamment GJB 1263A, annexe D, SAE ARP5921 et la méthode d'évaluation de la cokéfaction en phase gazeuse VPC. Il est adapté à l'évaluation de la tendance à la cokéfaction des huiles lubrifiantes synthétiques aéronautiques de type ester en présence de phases gazeuse et huileuse, simulant ainsi les conditions des conduits de ventilation des paliers. Lors de la vérification de la navigabilité des huiles de lubrification pour turbines, il est nécessaire d'évaluer la propension du mélange de leurs vapeurs et de l'air à générer des dépôts de carbone nocifs sur la surface des composants chauds, tels que les conduits de ventilation du moteur, par oxydation à haute température ou par craquage thermique en conditions d'immersion à haute température. La norme technique « Huiles de lubrification pour moteurs d'aéronefs civils » (CTS0-2C704) de l'Administration de l'aviation civile de Chine (CAAC) stipule clairement que les huiles de lubrification pour turbines doivent subir un test de cokéfaction en phase gazeuse afin de déterminer leur propension à former des dépôts de carbone dans la zone des conduits de ventilation à haute température des moteurs à turbines d'aéronefs, sans immersion dans l'huile. Il est requis de consigner la quantité de dépôts dans le tube de mesure, ainsi que le taux de variation de la viscosité cinématique à 40 °C et la variation de l'indice d'acide de l'huile de lubrification avant et après le test. En combinant des méthodes standard, des recherches sur des prototypes étrangers et des enquêtes normalisées, notre société a développé, conçu et produit de manière indépendante le testeur de cokéfaction en phase gazeuse VPC, qui répond aux exigences de la méthode de ce test et dont elle est le seul fabricant en Chine.

Overview

The VPC Gas Phase Coking Tester complies with the requirements of test standards including GJB 1263A Appendix D, SAE ARP5921, and the VPC Gas Phase Coking Evaluation Method. It is suitable for evaluating the coking tendency of ester-type synthetic aviation lubricating oils under the mixed state of air and oil phases, so as to simulate the condition of ventilation pipes in bearing chambers.When conducting airworthiness verification on the performance of turbine lubricating oils, it is necessary to measure the tendency of the mixture of their vapor and air to generate harmful carbon deposits on the surface of hot-end components such as engine ventilation pipes through high-temperature oxidation or thermal cracking reactions under high-temperature immersion conditions. The Civil Aviation Administration of China (CAAC) technical standard dddhhhCivil Aircraft Engine Lubricating Oilsdddhhh (CTS0-2C704) clearly stipulates that turbine lubricating oils must undergo a gas phase coking test to determine the tendency of lubricating oils to form carbon deposits in the high-temperature ventilation pipe area of aviation turbine engines without oil immersion. It is required to report the deposition amount in the measuring tube, as well as the 40℃ kinematic viscosity change rate and acid value change of the lubricating oil before and after the test.Combining standard methods, foreign prototype research and standard investigation, our company has independently developed, designed and produced the VPC Gas Phase Coking Tester, which meets the method requirements of this test and is the only manufacturer of this product in China.
