FIELD: motors and pumps.
SUBSTANCE: simulation device contains an oil batcher, a dispersion chamber and a lubricant oil decomposition chamber (1). At the air outlet downstream the chamber the diffuser (2) is located. On the chamber the heater (3) with the thermocouple (4) and the thermorelay (5) is installed. The device includes the air duct (6) supplying the pumped-over hot air into the lubricant oil decomposition chamber connected through the manometer (7) to the air compressor (8). The device contains the cylinder (13) filled with ultra-pure nitrogen, (23, 24) the sealed gage tank with air cavity with oil and a cover for oil filling, with the oil pipeline connected to it through the gas pipeline with the regulator (12), the adapter (11) and cap nuts. The gage tank (9) is connected through the adapter (11) with cap nuts (20, 21) to the measured capillary (15) in a cooling jacket (16) with circulating water through the thermostat with the pump (18) and radiators, attached to the decomposition chamber by means of the cap nut (22) and the sealing cone (25). Also the device comprises the additional chamber (26) screwed to the main decomposition chamber of (1) coaxially and sealed with a gasket (27), with the rod with a flywheel (17) installed inside, with threaded and non-threaded parts. Meanwhile the threaded part is implemented with a possibility of movement in the internal washer with a thread (28) for adjustment of the decomposition chamber volume and change of conditions of simulation of oil concentration, while the non-threaded part is sealed in a gland with graphite seal (29).
EFFECT: improvement of accuracy of simulation of composition of oil decomposition products in aviation gas-turbine engines.
