Its main function is to spray humidified air into the interior of the engine intake duct to simulate the working conditions of the engine in a high-humidity environment, so as to evaluate the performance and reliability of the engine.

[0003] During the test and measurement process of an aero-engine, when the simulated environment is low temperature and high humidity, under low temperature conditions, the sprayed water mist may freeze inside the spray guide cylinder and at the spray holes, blocking the spray holes, thus affecting the normal operation of the test and reducing the test efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that during the test and measurement process of an aero-engine, when the simulated environment is low temperature and high humidity, under low temperature conditions, the sprayed water mist may freeze inside the spray guide cylinder and at the spray holes, blocking the spray holes, thus affecting the normal operation of the test and reducing the test efficiency.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an aero-engine intake air humidification test device, including a spray guide cylinder, a delivery pipe and an atomization water tank. The two ends of the delivery pipe are respectively installed and connected to the outlet of the atomization water tank and the inlet of the spray guide cylinder. A plurality of spray holes are opened on the inner wall of the spray guide cylinder. An intake valve pipe is arranged at the bottom of the atomization water tank. A drain valve pipe is arranged at the bottom of the atomization water tank. An electrical control box is arranged on one side of the atomization water tank. A protection device is arranged on the outer surface of the spray guide cylinder. The protection device can suck external air into the air guide cover through the fan blades, and then pass through the electric heating wire mesh to perform heat exchange to raise the temperature, and then transport it into the air guide ring frame and the air guide pipe. Then, it contacts with the spray guide cylinder through the air guide pipe to perform heat exchange, so as to increase the temperature at the spray holes of the spray guide cylinder, achieving the effect of preventing ice blockage.

[0006] The effects achieved by the above components are as follows: When conducting a test on an aero-engine, the spray deflector is connected to the engine intake delivery pipe, and then water is added to the atomization water tank. Then, the ultrasonic atomization module inside the atomization water tank is controlled by the electrical control box to generate high-frequency oscillations. The ultrasonic atomization module here consists of several ultrasonic atomizers, which atomize water molecules into small molecule droplets. At the same time, an external air source is connected to the intake valve pipe at the bottom of the atomization water tank, and gas is introduced into the interior of the atomization water tank to roll and stir the liquid in the tank and increase the pressure in the tank. When not conducting a test, the water inside the atomization water tank can be drained through the drain valve pipe and then transported through the delivery pipe to the interior of the spray deflector. The atomized small molecule droplets will be ejected through several spray holes inside the spray deflector, mixing with the air inhaled by the engine to achieve the effect of humidifying the air, and then entering the intake duct of the aero-engine to simulate the working conditions of the aero-engine in a high-humidity environment, thereby evaluating the performance and reliability of the engine. If the simulated environment is low temperature and high humidity, the protection device can be activated to locally heat the inner wall spray holes of the spray deflector through heat exchange to prevent water mist from freezing at the spray holes and ensure the normal operation of the test, improving the test efficiency.

At the same time, the electric heating wire mesh 211 is started for heating. When the air sucked by the fan blade 24 passes through the electric heating wire mesh 211, heat exchange will occur to increase the temperature of the air, and then enter the inside of the air guide ring frame 26 and be respectively transported to a plurality of air guide pipes 27 to heat up the inner walls of the air guide pipes 27, so that heat exchange occurs between the inner walls of the air guide pipes 27 in contact with the inner wall of the spray deflector cylinder 1 and the inner wall of the spray deflector cylinder 1, locally heating the spray holes 4 to avoid icing of the water mist at the spray holes 4 when the temperature is too low, so as not to affect the normal operation of the test and improve the test efficiency. The protective device 2 further includes a plurality of filter nets 28, the outer surfaces of which are fixedly installed in the inner walls at the ends of the air guide pipes 27 far from the air guide ring frame 26.

[0039] Working principle: When conducting a test on an aero-engine, the spray guide cylinder 1 is connected to the engine intake delivery pipe 5, and then water is added into the atomization water tank 6. Then, the ultrasonic atomization module inside the atomization water tank 6 is controlled by the electrical control box 9 to generate high-frequency oscillations. Here, the ultrasonic atomization module is composed of a number of ultrasonic atomizers, and the model of the ultrasonic atomizer is WH-801. The water molecules are atomized into small molecule droplets. At the same time, an external air source is connected to the intake valve pipe 7 at the bottom of the atomization water tank 6, and gas is introduced into the interior of the atomization water tank 6 to play a role in tumbling and stirring the liquid in the tank and increasing the pressure in the tank. When not in use for testing, the water inside the atomization water tank 6 can be drained through the drain valve pipe 8, and then conveyed to the interior of the spray guide cylinder 1 through the delivery pipe 5. The atomized small molecule droplets will be ejected through a number of spray holes 4 inside the spray guide cylinder 1, so as to be mixed with the air inhaled by the engine, achieving the effect of humidifying the air, and then entering the intake duct of the aero-engine, thereby simulating the working conditions of the aero-engine in a high-humidity environment, and thus evaluating the performance and reliability of the engine. If the simulated environment is low temperature and high humidity, the motor 23 on the first support 2 is controlled by the electrical control box 9 to drive the fan blade 24 to rotate inside the inner wall of the air guide cover 21, sucking the external air into the air guide cover 21 through the air intake hole 25. At the same time, the electric heating wire mesh 211 is started for heating. When the air inhaled by the fan blade 24 passes through the electric heating wire mesh 211, heat exchange will occur to increase the temperature of the air. Then, after entering the interior of the air guide ring frame 26, it is respectively conveyed to a number of air guide pipes 27 to heat up the inner walls of the air guide pipes 27, causing heat exchange with the inner wall of the spray guide cylinder 1 in contact with the inner wall of the spray guide cylinder 1, and locally heating the spray holes 4 to prevent the water mist from freezing at the spray holes 4 when the temperature is too low, so as not to affect the normal operation of the test and improve the test efficiency. When the fan blade 24 rotates, it will drive the reinforcement rod 294 and the brush 291 to rotate accordingly, causing the limit block 293 to rotate in the limit slot 292. The end of the brush 291 with bristles will move in a circular motion at the air intake hole 25 to clean the dust attached to the air, preventing the air intake hole 25 from being blocked and affecting the use of the protection device 2.

[0040] When the brush 291 rotates, it will push one end of the cam rod 32 to rotate in a circular motion with one end as the center, driving the first torsion spring 33 to deform. The other end of the first torsion spring 33 then pushes one end of the knocking rod 34 to rotate in a circular motion on the second bracket 31. While driving the second torsion spring 36 to deform, the knocking hammer 35 at the other end thereof knocks on the outer surface of the spray guide cylinder 1, vibrating the outer surface and the inner wall of the spray guide cylinder 1. This can reduce the adhesion of water mist at the spray holes 4, thereby reducing the possibility of icing and achieving the effect of assisting the protection device 2 in protection.
