The utility model can simply and quickly detach the movable ring from the rear axle diameter by utilizing the special hydraulic device, and can ensure the precision of the movable ring and the completeness of the graphite ring.
Description
Technical Field
The utility model belongs to the field of gas turbine assembly, and particularly relates to a hydraulic device for disassembling a precise moving ring.
Background
The movable ring is a key part on the rear shaft diameter of the low-pressure turbine rotor, forms labyrinth seal with the graphite ring, the gas jacket, the protruding parts of the movable blades and the like, and seals lubricating oil into the bearing cavity by using gas pressure. The movable ring is assembled adjacently to the graphite ring, the precision of the matching surface is high, and the movable ring is in interference fit with the rear shaft diameter. Therefore, how to detach the moving ring from the rear shaft diameter and to ensure accuracy and integrity of the graphite ring is a key issue in detaching the moving ring. The puller is directly used for disassembling, and the disassembly of the movable ring can be influenced due to the small contact area and uneven stress.
Disclosure of Invention
The utility model aims to provide a hydraulic device for disassembling a precise moving ring, which solves the problem that the moving ring is ensured to be precise and the integrity of a graphite ring is ensured in the disassembling process.
The hydraulic device for disassembling the precise movable ring is characterized by comprising a clamp, a blocking tool and a hydraulic puller; the clamp clamps the movable ring and fixes the clamp through a screw; the plugging tool is used for plugging the hollow part of the turbine shaft; the hydraulic puller is connected with the clamp.
Further, the movable ring is assembled adjacently to the graphite ring, and the movable ring is in interference fit with the rear shaft diameter.
The utility model has the beneficial effects that: the utility model can simply and quickly detach the movable ring from the rear axle diameter by utilizing the special hydraulic device, and can ensure the precision of the movable ring and the completeness of the graphite ring.
Drawings
FIG. 1 is a diagram of the overall structure of the present utility model;
FIG. 2 is a schematic view of the structure of the clamp of the present utility model;
FIG. 3 is a schematic diagram of a plugging tool according to the present utility model;
fig. 4 is a schematic view of the hydraulic puller of the present utility model.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1 to 4, a hydraulic device for detaching a precision moving ring comprises a clamp 2, a blocking tool 4 and a hydraulic puller 3; the clamp 2 clamps the movable ring 1 and fixes the clamp through screws; the plugging tool 4 is used for plugging the hollow part of the turbine shaft; the hydraulic puller 3 is connected with the clamp. The movable ring 1 is assembled adjacently to the graphite ring 5, and the movable ring 1 is in interference fit with the rear shaft diameter 6.
The application process of the utility model is as follows: the movable ring 1 is clamped by the clamp 2, the clamp 2 is fixed by a screw, and then the hollow part of the turbine shaft is blocked by the blocking tool 2. The clamp 2 is pulled taut by a hydraulic puller 3, and then slowly pressurized, so that the clamp 2 is slowly pulled out from the rear shaft diameter 6 with the movable ring 1.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
