Description
Technical Field
The disclosure relates to the technical field of assembly, in particular to a gas turbine high-pressure compressor hole detection rotator and a using method and system thereof.
Background
The hole detection is one of important means for detecting the fault of the gas turbine, and the fault detection is carried out on the internal structure of the gas turbine on the basis of not dismounting or few dismounting parts, so that the fault detection efficiency of the gas turbine is greatly improved. When the hole probe detects the gas turbine rotor, the gas turbine rotor needs to be rotated, so that the conditions of parts at different circumferential positions are detected.
When the hole detection is used for detecting the double-shaft gas turbine, the arrangement form of the double-shaft gas turbine is shown in figure 1, a low-pressure gas compressor is connected with a low-pressure turbine through a shaft 1, a high-pressure gas compressor is connected with a high-pressure turbine through a shaft 2, and when the hole detection is used for detecting the low-pressure gas compressor, the shaft 1 is exposed outside, so that a low-pressure rotor can be directly rotated by rotating the shaft 1. When the hole probe detects the high-pressure compressor, the shaft 2 is positioned in the engine and cannot directly rotate, and the high-pressure compressor can only rotate through rotating a starting gear box connected with the shaft 2 by external force. The starting gear box is located in the position, close to the rotating shaft, inside the gas turbine, as shown in fig. 1, an interface capable of rotating an internal gear is usually reserved on the starting gear box, the interface is circular as shown in fig. 2, a rectangular hole is formed in the center of the interface, and 6 circular holes are evenly distributed on the periphery of the interface.
The existing solutions usually use a long rod with the same rectangular cross section to be inserted into a rectangular hole in the middle, and rotate the long rod to rotate the starting gear box interface, as shown in fig. 3. This method has a number of disadvantages: 1. it is relatively laborious and rotates slowly. 2. The safety is poor, and due to the adoption of the rectangle with the equal section, enough space is required to be ensured around the long rod during rotation, otherwise, other parts in the gas turbine can be damaged during rotation. When the rectangular long rod is used for a long time, the rectangular long rod can be abraded, looseness occurs between the rectangular long rod and the hole, and the transmission efficiency is reduced.
Therefore, the existing hole detection rotation scheme has the technical problems of great rotation force and poor safety.
