喷气燃料中微量悬浮物的过滤分离装置的研制

Development of Filtrate Characteristics Experimental Device for Minim Suspended Impurity in Jet Fuel

研制了喷气燃料中难分离微量悬浮物的过滤试验装置,通过标准试验手段来判断某喷气燃料中的悬浮物是否能够通过目前外场过滤系统过滤净化处理,减少目前普遍使用的用目视检查方法判断喷气燃料洁净度的误差。研制的标准滤芯满足设计要求。按照标准试验滤芯相似原理即过滤精度、流量和压差三方面相似设计的标准滤芯与小型滤芯和外场大滤芯效果相当,在5～9级范围内Abakus C颗粒计数仪测得的NAS1638污染度可以代替俄罗斯ПКЖ-904A颗粒计数仪测得的ΓОСТ17216污染度。使用过滤试验装置有利于对喷气燃料质量管理和贮运过程中的洁净度进行科学评价。

In order to settle the eyeballing error of jet fuel clean class evaluation which is a difficult problem in fuel production factories, a filtrate characteristics experimental device which aims to simulate the practical filtration installation for suspended impurity in jet fuel was developed. Based on the standard filter resemble principle, the filtration precision, flux and pressure-difference of the developed filtrate characteristics experimental device were designed to correspond to the practical filtration installation. In the level 5-9, the NAS1638 oil clean class detected by Abakus C particulates counter could be used to substitute the FOCT17216 oil clean class detected by ПK Ж-904A particulates counter. Reliability and correlation to the practical filtration installation was tested, and mechanism of filtration was suggested. The results show that the developed filtrate characteristics experimental device achieves the design parameters, and the device is suitable to the simulation evaluation of jet fuel clean class in the process of storage, transportation and quality management.
