Description
Technical Field
The invention belongs to the technical field of aviation test equipment, and particularly relates to a pumping pressure type water atomization mixing device and a using method thereof.
Background
Aviation kerosene can be contaminated with moisture for a variety of reasons during storage, transportation, filling and use. If the oil storage container is not dry and has residual moisture, the sealing is not tight, rain, snow, ice and frost fall in the filling process, the condensation of water vapor and the like can cause the aviation kerosene to have some moisture, and the water exists in three possible forms of suspended water, dissolved water and free water.
The freezing point of aviation fuel is increased if the aviation fuel contains moisture. If the airplane flies in cold air temperature conditions for a long time, water in fuel oil can be frozen into ice, oil filters or filter screens can be blocked, accessories and systems can be disabled, fuel oil flowing to an engine can be slowed down or completely interrupted, and the engine can be flamed out, so that flight safety is endangered. GJB3577-99 'icing requirements and tests of aircraft fuel systems and accessories' has the following requirements on the icing of the fuel system:
the system works continuously: the fuel system should have the ability to continue operation when the fuel without the anti-icing additive is cooled to any temperature between-55 c at 27 c moisture saturation. The system works in emergency: the fuel without anti-icing additive is saturated at 27 ℃ with water, 0.2ml of free water is added per litre of fuel, and the fuel is cooled to the most critical icing conditions that may be encountered during operation, the fuel system should be able to allow the aircraft to continue flying for 30min at the minimum engine power required to not compromise flight safety. Meanwhile, the CCAR25 department requires that the fuel system for a turbine engine must be able to continue operating throughout its flow and pressure ranges when using fuel in the following conditions: the fuel was first saturated with water at 27 c and contained 2ml of free water added per 10 litres of fuel and then cooled to the most critical icing conditions likely to be encountered in operation.
Disclosure of Invention

The adjustable metering pump 4 can adjust the flow speed of water; because the water needed to be injected in the fuel test is less, and the water injection flow needs to be matched with the fuel flow, the adjustable metering pump 4 is adopted. If the air tank 13 is not provided, the atomizing nozzle 7 has a pulsating water outlet phenomenon, and the water injection flow and the pressure jump are increased, so that the air tank 13 is mainly used for buffering the pressure in a water injection pipeline to achieve the purpose of stable water injection.
