Description

Technical Field

[0002] Steam turbine: A steam turbine, also known as a steam turbine engine, is a rotary steam power device. High-temperature and high-pressure steam passes through a fixed nozzle to become an accelerated air flow and then jets onto the blades, causing the rotor equipped with the blade row to rotate and perform external work at the same time. Steam turbines are the main equipment in modern thermal power plants and are also used in the metallurgical industry, chemical industry, and ship power plants. The following problems exist in the quenching devices for steam turbine rotating rings in the prior art:

[0003] 1. When the quenching devices in the prior art quench the steam turbine rotating ring, most of them cannot stir the coolant in the quenching pool. Since the coolant in the quenching pool is stationary, the subsequent quenching effect of the steam turbine rotating ring is affected;

When the quenching devices in the prior art quench the steam turbine rotating ring, they usually place the steam turbine rotating ring inside the coolant and complete the quenching of the steam turbine rotating ring in a stationary state.

[0051] A quenching method for a rotating ring of a steam turbine includes the following steps:

[0052] S1. Stir the coolant

[0053] By rotating the stirring rod 21, the stirring rod 21 makes the stirring blades 24 rotate through the fixed sleeve 22 and the rotating plate 23. The stirring blades 24 stir the coolant in the quenching pool 1, making the coolant flow continuously inside the quenching pool 1.

[0054] S2. Rotation of the rotating ring of the steam turbine

[0055] By driving the arc-shaped slider 33 to rotate around the axis of the quenching pool 1, the arc-shaped slider 33 makes the material tray 14 rotate around the axis of the quenching pool 1 through the connecting seat 34, the bottom rod 16 and the movable rod 18. The rotating ring of the steam turbine in the material tray 14 rotates synchronously.

[0056] S3. Reciprocating lifting of the rotating ring of the steam turbine

[0057] By driving the sleeve 41 to lift vertically, the sleeve 41 makes the guide block 43 slide vertically reciprocally. The guide block 43 makes the material tray 14 lift vertically reciprocally through the movable rod 18. The rotating ring of the steam turbine in the material tray 14 lifts and lowers synchronously.

[0058] Working principle: When quenching the rotating ring of the steam turbine, the staff first place the heat-treated rotating ring of the steam turbine in the tray 14, and then start the servo motor 25. The drive shaft of the servo motor 25 makes the stirring rod 21 rotate. The stirring rod 21 makes multiple stirring blades 24 rotate through the fixed sleeve 22 and multiple rotating plates 23. While the multiple stirring blades 24 are rotating, they stir the coolant in the quenching pool 1, causing the coolant to continuously flow inside the quenching pool 1, thus conveniently achieving the stirring of the coolant. Compared with the traditional technology where the coolant in the quenching pool 1 is stationary, the quenching effect of the subsequent rotating ring of the steam turbine is improved;

[0059] Meanwhile, when the stirring rod 21 rotates, the stirring rod 21 makes the first rotating rod 36 rotate synchronously through two synchronous wheels 37 and a synchronous belt 38. The first rotating rod 36 makes the first gear 39 rotate. The first gear 39 drives the external gear ring 35 to rotate. The external gear ring 35 makes the arc-shaped slider 33 slide along the surface of the circular guide rail 31 with the center of the circular guide rail 31 as the center of the circle. The arc-shaped slider 33 makes the tray 14 rotate with the center of the quenching pool 1 as the center of the circle through the connecting seat 34, two bottom rods 16 and two movable rods 18. The rotating ring of the steam turbine in the tray 14 rotates synchronously;

[0060] Meanwhile, one bottom rod 16 makes the second rotating rod 53 and the second gear 52 rotate with the center of the quenching pool 1 as the center of the circle through the support plate 54, the first support rod 55 and the first rotating sleeve 56. The internal gear ring 51 drives the second gear 52 to rotate. The second gear 52 makes the second rotating rod 53 rotate. The second rotating rod 53 makes the first transmission rod 57 rotate through two meshing first bevel gears 58. The first transmission rod 57 makes the second bevel gear 59 rotate. The second bevel gear 59 drives the second transmission rod 6 to rotate through a third bevel gear 63. The second transmission rod 6 drives the fourth bevel gear 65 to rotate through another third bevel gear 63. The fourth bevel gear 65 makes the third rotating rod 64 rotate. The third rotating rod 64 makes the driving rod 67 rotate with the center of the rotating disk 66 as the center of the circle through the rotating disk 66. The driving rod 67 drives the push rod 49 to reciprocate. The push rod 49 pushes the U-shaped seat 46 to reciprocate vertically up and down through the connecting sleeve 48 and the rotating shaft 47. The U-shaped seat 46 makes two sleeves 41 reciprocate vertically up and down through the second connecting plate 45 and the first connecting plate 411. The two sleeves 41 make four guide blocks 43 reciprocate vertically along the inner walls of the four guide grooves 42. The four guide blocks 43 make the tray 14 reciprocate vertically up and down through two movable rods 18. The rotating ring of the steam turbine in the tray 14 synchronously moves up and down. The rotating ring of the steam turbine rotates with the center of the quenching pool 1 as the center of the circle and reciprocates vertically up and down to uniformly contact the coolant in the quenching pool 1, thus conveniently achieving the quenching of the rotating ring of the steam turbine, and effectively improving the quenching effect of the rotating ring of the steam turbine.
