Description
Technical field
The utility model relates to a kind of test macro of airplane spare parts, especially relates to the test macro of the temperature control thermostat of A320 sequence aircraft.
Background technology
Regulated through the bleed valve by the high-pressure hot air that engine comes, the bleed valve has two effects here: the one, regulate bleed pressure to specific pressure, and the 2nd, play the shutoff effect.In the outlet of bleed valve Overpressure Valve has been installed also, Overpressure Valve superpressure do not occur for the protection of pipeline here, in case line pressure is higher than setting, Overpressure Valve will be closed automatically.
Since higher from the high-pressure hot air temperature that engine is drawn, before annex is supplied with downstream, be cooled off in advance, therefore in bleed air line the precooling heat interchanger has been installed.This precooling heat interchanger is the heat exchanger of an air-air formula, used cold limit air is from engine blower, cold limit air mass flow is controlled by Fan Air Valve, by control Fan Air Valve aperture, can control precooling heat exchanger heat limit outlet bleed temperature, normally be 210 degree, temperature control thermostat is installed on the hot limit outlet bleed air line of precooling heat interchanger, experiences the pipeline temperature.
