Description

Technology Field

[0001] The present invention relates to a concentricity measuring device, and more specifically, to a concentricity measuring device for an interstage seal and blade ring of a gas turbine. Background Technology

[0003] During gas turbine construction, measuring and adjusting the concentricity of the interstage seals requires a significant amount of maintenance time during the construction period. Furthermore, failure to measure the concentricity of the blade rings can result in cases where assembly is impossible (e.g., the blade rings tilting inward toward the horizontal plane due to high-temperature operation), which may lead to problems such as reduced maintenance quality or increased maintenance time.

[0004] Specifically, the measurement and adjustment of the interstage seal concentricity of the gas turbine was previously performed using a dial gauge, but since concentricity is measured from the top, bottom, left, and right using a dial gauge, a significant amount of maintenance time is required. In the case of the blade ring, since the inclination inward on the horizontal plane was not measured previously, there may be instances where the blade ring cannot be assembled, so it is necessary to seek a solution for improvement. The problem to be solved

[0006] The present invention has been devised to solve the above-mentioned problems, and the objective of the present invention is to provide a gas turbine interstage seal and blade ring concentricity measuring device that measures concentricity based on position data measured at each point within the object to be measured and outputs the results to a screen in real time, thereby enabling an operator to perform concentricity adjustment work while checking the concentricity measurement results in real time. means of solving the problem

[0008] According to one embodiment of the present invention for achieving the above objective, a gas turbine interstage seal and blade ring concentricity measuring device comprises: a transmitter attached to a concentricity measuring object to measure position data for concentricity measurement and output a laser; a receiver attached to the opposite side of the transmitter within the concentricity measuring object to measure position data for concentricity measurement and receive the laser output by the transmitter; and a monitor device that calculates concentricity and outputs it to a screen when position data is received from the transmitter and the receiver, respectively.

[0009] In addition, the transmitters are provided in multiple numbers and, when attached to the object to be measured for concentricity, can be attached at spaced intervals.

[0010] And the object to be measured for concentricity is an interstage seal or a blade ring, and a plurality of transmitters may be attached at regular intervals on the inner side of the interstage seal when attached to the interstage seal, and attached at regular intervals on the outer side of the blade ring when attached to the blade ring.

[0011] In addition, receivers may be provided in multiple numbers and may be attached to the opposite side of each transmitter within the gas turbine interstage seal or blade ring to receive the laser output by each transmitter.

[0012] In addition, the transmitter and receiver may be made of a magnetic material in part or in whole at the bottom, so that they can be attached to the object to be measured for concentricity using magnetism.

[0013] Meanwhile, according to another embodiment of the present invention, a gas turbine interstage seal and blade ring concentricity measuring device comprises: a plurality of transmitters attached to the gas turbine interstage seal or blade ring at spaced intervals to measure position data for concentricity measurement and output a laser; a plurality of receivers attached to the opposite side of each transmitter within the gas turbine interstage seal or blade ring to measure position data for concentricity measurement and receive the laser output by the transmitter; and a monitor device that calculates concentricity and outputs it to a screen when position data is received from each of the plurality of transmitters and receivers. Effects of the invention

[0015] As described above, according to the embodiments of the present invention, concentricity is measured based on position data measured at each point within the object to be measured, and this is displayed on a screen in real time, allowing an operator to perform concentricity adjustment work while checking the concentricity measurement results in real time, thereby improving the efficiency of concentricity measurement and adjustment work.

Specific details for implementing the invention

[0018] The present invention will be described in more detail below with reference to the drawings. To clearly explain the invention, parts unrelated to the description have been omitted from the drawings, and in the drawings, the width, length, thickness, etc., of the components may be exaggerated for convenience.

[0019] FIG. 1 is a drawing provided for the configuration description of a concentricity measuring device for a gas turbine interstage seal (10) and a blade ring (20) according to one embodiment of the present invention.

[0020] The concentricity measuring device for the gas turbine interstage seal (10) and blade ring (20) according to the present embodiment (hereinafter collectively referred to as the 'concentricity measuring device') is provided to measure concentricity based on position data measured at each point within the interstage seal (10) or blade ring (20), which is the object to be measured for concentricity, and to output the results to a screen in real time.

[0021] To this end, the concentricity measuring device may be composed of a transmitter (110), a receiver (120), and a monitor device (130).

[0022] The transmitter (110) can be attached to the interstage seal (10) or blade ring (20), which is the object for measuring concentricity, and can output a laser.

[0023] Additionally, the transmitter (110) can measure location data (e.g., coordinate data, etc.) at the attached point and transmit it to the monitor device (130).

[0024] The receiver (120) is attached to the opposite side of the transmitter (110) within the interstage seal (10) or blade ring (20), which is the object for measuring concentricity, and can receive the laser output by the transmitter (110).

[0025] Additionally, the receiver (120) can measure location data (e.g., coordinate data, etc.) at the attached point and transmit it to the monitor device (130).

[0026] When the monitor device (130) receives position data from the transmitter (110) and the receiver (120), respectively, it can calculate the concentricity and output it to the screen.

[0027] FIG. 2 is a drawing illustrating the appearance of an interstage seal (10) and a blade ring (20) of a gas turbine, and FIG. 3 and FIG. 4 are drawings illustrating the appearance of a transmitter (110) and a receiver (120) attached to an interstage seal (10) and a blade ring (20) according to an embodiment of the present invention.

[0028] The transmitters (110) are provided in multiple numbers and, when attached within the interstage seal (10) or blade ring (20), can be attached spaced apart at regular intervals.

[0029] Specifically, when the transmitter (110a) is attached to the interstage seal (10), it may be attached to the inner side of the interstage seal (10) at a spaced interval.

[0030] At this time, receivers (120a) are also provided in multiple numbers and can be attached to the opposite side of each transmitter (110a) within the gas turbine interstage seal (10) to receive the laser output by each transmitter (110a).

[0031] For example, the transmitter (110a) can be attached at the 1:30, 3:00, 4:30, and 6:00 directions inside the interstage seal (10), respectively, spaced apart at 45-degree intervals as shown in FIGS. 3 and 4.

[0032] And the receiver (120a) can be attached at the 7:30, 9:00, 10:30, and 12:00 directions, respectively, inside the interstage seal (10) on the opposite side of each transmitter (110a), spaced apart at 45-degree intervals.

[0033] Additionally, when the transmitter (110b) is attached to the blade ring (20), it may be attached to the outer side of the blade ring (20) at a spaced interval.

[0036] And the receiver (120b) can be attached at the 7:30, 9:00, 10:30, and 12:00 directions on the outer side of the blade ring (20) corresponding to the opposite side of each transmitter (110), spaced apart at 45-degree intervals.

[0037] The operator can perform concentricity adjustment work while checking the results of the concentricity measurement (calculation) of the interstage seal (10) or blade ring (20) displayed in real time on the screen of the monitor device (130).

[0038] Specifically, the operator can perform a concentricity adjustment operation by comparing the reference value of the interstage seal (10) with the concentricity measurement result of the interstage seal (10) displayed on the screen of the monitor device (130) and adjusting the deviation of at least one side of the interstage seal (10) in units of 0.05 mm.

[0039] Additionally, the operator can perform concentricity adjustment work by comparing the reference value of the blade ring (20) with the concentricity measurement result of the blade ring (20) displayed on the screen of the monitor device (130) and adjusting the deviation of the inward tilt of the blade ring (20) on the horizontal plane.
