FIELD: testing equipment.SUBSTANCE: invention is designed for sampling and precise comprehensive assessment of pollution of air samples (from air supplied into a system of aircraft pilot cabin conditioning), sampled from a compressor of a gas turbine aviation engine (GTE) during its bench testing, and further gas chromatographic analysis of samples for content of hazardous admixtures. A laboratory complex for sampling and gas chromatographic analysis of air samples includes a complex of air sampling 6 with a unit of samplers 7 and a control panel 8, a complex for gas chromatographic analysis of air samples 3 with a control panel 4, a package 9 for transportation of adsorption packets 10 and a container 11 for storage of concentrators 12. The laboratory complex is also equipped with plants for supply of gases 5, pumping of calibrating gas mixture 2 and definition of working volumes of a vacuumised part of the item 1. At the same time the plant for supply of gases 5 is simultaneously connected with the plant for pumping of the calibrating gas mixture 2 and with the complex of gas chromatographic analysis of air samples 3, and the plant for definition of working volumes of the vacuumised part of the item 1 is connected with the complex of air sampling 6.EFFECT: improved operational properties, provision of sampling and precise comprehensive assessment, total error of measurement of pollution of air samples from a GTE compressor under bench testing, higher quality of indirect control of oil seals used in supports of the GTE compressor rotor.8 dwg |
