O Testador de Coqueamento em Fase Gasosa VPC atende aos requisitos de normas de teste, incluindo GJB 1263A Apêndice D, SAE ARP5921 e o Método de Avaliação de Coqueamento em Fase Gasosa VPC. É adequado para avaliar a tendência de coqueamento de óleos lubrificantes sintéticos de aviação do tipo éster em estado misto de ar e óleo, simulando assim as condições de tubulações de ventilação em câmaras de rolamentos. Ao realizar a verificação de aeronavegabilidade do desempenho de óleos lubrificantes para turbinas, é necessário medir a tendência da mistura de seu vapor e ar em gerar depósitos de carbono prejudiciais na superfície de componentes da extremidade quente, como os tubos de ventilação do motor, por meio de reações de oxidação em alta temperatura ou craqueamento térmico sob condições de imersão em alta temperatura. A norma técnica da Administração de Aviação Civil da China (CAAC) "Óleos Lubrificantes para Motores de Aeronaves Civis" (CTS0-2C704) estipula claramente que os óleos lubrificantes para turbinas devem ser submetidos a um teste de carbonização em fase gasosa para determinar a tendência dos óleos lubrificantes em formar depósitos de carbono na área do tubo de ventilação de alta temperatura de motores de turbina de aviação, sem imersão em óleo. É necessário relatar a quantidade de depósito no tubo de medição, bem como a taxa de variação da viscosidade cinemática a 40 °C e a variação do índice de acidez do óleo lubrificante antes e depois do teste. Combinando métodos padrão, pesquisa de protótipos estrangeiros e investigação padronizada, nossa empresa desenvolveu, projetou e produziu de forma independente o Testador de Coqueamento em Fase Gasosa VPC, que atende aos requisitos metodológicos deste teste e é o único fabricante deste produto na China.

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.
