[0055] Fig.12 This is a schematic diagram of the spray quenching state of an aviation turbine disk. The structure of the sprayer is as follows: Fig.11As shown. The sprayer adopts the existing structure, and the nozzle of the sprayer is set according to the shape of the turbine disk, so that the distance from the nozzle to the turbine disk is equal. The material of the aviation turbine disk is a nickel-based high-temperature alloy, and the overall shape can be divided into a cylindrical part and a truncated cone part.

The lower bottom surface of the truncated cone part has a diameter of 67.65mm, and the upper bottom surface has a diameter of 118.95mm and a height of 34.5mm. When quenching the turbine disk, a spray cooling device is set on both sides of the turbine disk, and the two surfaces of the turbine disk are quenched respectively by the two spray cooling devices.

[0056] Here’s how to use it:

[0057] The five electric cylinders 12 are fixed to the third mounting holes 19 of the partition plate 10 using locking screws 32. The central electric cylinder 12 is threadedly connected to the first plunger disk 7. The two electric cylinders 12 distributed on the left and right sides of the concentric circle with a diameter of 122 mm with the partition plate 10 as the center are threadedly connected to the second plunger disk 82. The two electric cylinders 12 distributed on the front and rear sides of the concentric circle with a diameter of 182 mm with the partition plate 10 as the center are threadedly connected to the third plunger disk 9. The three plunger disks are concentrically distributed.

[0058] The plunger rod 4 is connected to the plunger disc by a threaded connection and positioned by a hexagonal prism limit platform 21. The plunger rods 4 are assembled on the plunger disc in a concentric circle from the inside to the outside. There are 6 plunger rods 4 on the first plunger disc 7, 15 plunger rods 4 on the second plunger disc 8, and 22 plunger rods 4 on the third plunger disc 9. The sealing plug 11 corresponds to the plunger rod 4 one by one and is assembled to the sprayer base plate 2 using a threaded connection and an O-ring. The plunger rods 4 are installed into the sealing plugs 11 one by one, and the cone valve 5 is installed on the plunger rod 4 using a threaded connection. Use the set screws 31 to install the shell 1 and the sprayer base plate 2 on the sprayer body 28, connect the transmission line from the wire hole 6 to the PLC control system, input instructions to test the operating status of each electric cylinder 12, and use the set screws 31 to fix the shell plate 3 to the shell 1 after the status detection is normal.

[0059] The electric cylinder 12 is controlled by PLC to adjust the initial position of the plunger rod 4 until the limit table 21 contacts the lower surface of the sealing plug 11. At this time, the cone valve 5 completely closes all the water nozzles 29. The center of the aviation turbine disk is thicker and thinner around. The quenching requires that the cooling rate in the center is faster than that in the surroundings. The first plunger disk 7 is moved downward by 6mm through the PLC control system, and the second plunger disk 8 and the third plunger disk 9 are moved downward by 4mm. At this time, the flow rate of the water nozzle 29 at the center of the sprayer body 28 is about 20% larger than that of the water nozzle 29 at the surrounding positions. Under the condition of the same air flow rate of the air nozzle 30, the spray concentration at the center is higher than that at the surroundings, and the cooling rate is faster, thereby achieving more precise quenching requirements for aviation turbine disks.

[0060] Therefore, the integrated high-speed spray cooling device with precise and controllable water-gas ratio by zone as described in the present invention can solve the problem that the existing high-speed spray cooling device cannot adjust the water-gas ratio by zone.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
