Abstract

PURPOSE:To reduce the load on an operator in charge of control by inputting respective planned values of a car room rotor, and its gap through a CAD (computer aided design) system, and reading the various planned values out of a drawing automatically. CONSTITUTION:The size of the rotor obtained by rotor size measurement 11 is stored in a rotor size file 14 by the processing function of a rotor size measurement/input system A. Then, the size of the car room obtained by room size measurement 21 is stored in a room size file 2 by the processing function of a room size measurement/input system B. A size control system C inputs measured values of the rotor size and room size from the systems A and B and planned values of gaps of the rotor and car room from the CAD system D respectively and stores them in a size control file 31, and then a measured value of the gap between the both is obtained from the difference in measured value between the rotor size and car room size and stored in the file 31. The system C, on the other hand, compares this measured value with the planned value of the gap which is inputted from the system D and records and outputs the measured value in identifiable form unless the difference is within a permissible range.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an inter-rotating machine for controlling gaps between rotating machines.
Regarding the i-management system.

[Prior Art] Generally, in rotating machines such as steam turbines, gas turbines, and even blowers, it is required to control whether the gap between the casing and the rotor matches the installation I value. The above-mentioned gap can be determined by inputting the 81 measuring method for the casing and rotor of the rotating machine into a computer and calculating the difference. The Ministry in charge of gap management uses the gap value (actual measurement value) determined by the computer as the installation t1 value read from the design drawing.
By comparing with 1 self (81 image value), gap management is
j Now.

[Problems to be Solved by the Invention] In the above-mentioned conventional gap management system, the actual gap value between the vehicle interior and the rotor is determined by computer processing. 1 in the setting
All reading from the drawings was done manually.

For this reason, there is a problem in that gap management becomes complicated. Also,
Since the deflection of the casing and the rotor, especially the deflection of the rotor, was not taken into account, the accuracy was poor and the gap management could not be practical.

Therefore, the technical object of the present invention is to enable gap management to be performed with high precision and practicality, and without placing a burden on the person in charge of management.

[Means for Solving the Problems and Their Effects] In order to solve the above technical problem, the present invention provides a measurement value input means for inputting each measurement value of the casing and rotor of a rotating machine, and a measurement value input means for inputting each measurement value of the casing and rotor of a rotating machine. In addition to the calculation means that calculates the gap value between the casing and the rotor based on the input data from the input means, the calculation means calculates the gap value between the casing and the rotor of the rotating machine, and the planned value of the gap between the casing and the rotor. In addition, there are provided a planned value input means for inputting planned values including planned values taking into account the deflection of the same-day tar, using a CAD system, and a dimension management means. The dimension management means determines whether the input data from the measurement value input means and the calculation result of the calculation means are outside the allowable range of the planned value input from the separate value input means, and determines whether or not the result of the determination is consistent. The input data and output results are recorded so that they can be identified (for example, by adding a specific identifying key *).

[Effects of invention The present invention has the following special effects.

■ Each of the casing, rotor, and gap of rotating machineryii
By inputting the 1-picture value from the CAD system, the reading of this kind of 1-picture value from the drawing can be automated, reducing the burden on the administrative ministry.

■ Since the rotor deflection is input into the CAD system, the practicality of the measurement results can be improved.

■ Input data from fit ill 1m input means,
Since the calculation result of the calculation means is automatically recorded, there is no need for transcription work, and the fear of writing errors is eliminated.

■ Just by visually checking the above-mentioned automatic recording contents, it is possible to easily identify whether or not the input data from the Ii1 measurement value input means, and furthermore the calculation results from the calculation means, are outside the allowable range of 31 pixel values. Easy to do.

Next, the operation of one embodiment of the present invention will be explained. The rotor dimensions of rotating machines that are subject to clearance control are "Rotor dimensions" 1 Measuring instrument 11
The measured value is stored in the rotor j method file 14 via the counter 13 by the processing function of the rotor dimension side measurement/input system. The O-Y dimension 11 measurements in the rotor dimension file 14 are CR
The screen is displayed on screen 15, and prints 1 to 1 are printed out by printer 16. In addition, the inner chamber of the rotating machine that is subject to clearance control is measured by the chamber dimension measuring device 21, and one measurement value is the mold chamber dimension! i1 Measurement 7/By the processing function of the input system B, the cabin dimension file 2 is sent via the counter 23.
It is stored in 4. The cabin dimension meter 8111 value in the ψ total dimension file 24 is displayed on the screen by the CRT 25 and printed out by the printer 26 as necessary. The dimension management system C uses the rotor dimension measurement values stored in the rotor dimension file 14 of the rotor dimension measurement/'input system A, and the rotor dimension measurement values stored in the vehicle interior dimension file 24 of the vehicle interior dimension measurement/'input system B. The measured values of the vehicle interior dimensions are input via a computer line and stored in the dimension management file 31 within the system C.

A CAD system D is also connected to the dimension management system C via a center file system F via a computer line. Dimension management system C uses CAD system D to determine the casing, rotor, and
and each planned value (one installation dimension) of the gap is inputted and stored in the dimension management file 31 within the system C. In this embodiment, the planned value includes a tolerance value. especially,
Regarding the planned value of the clearance, when considering rotor deflection,
It also includes each allowable value when not considered.

Dimension management system 1. C is rotor size 8! From input system A, take the 81 measurement value of [] - 1, and from the input system B, take the &1 measurement value of the cabin dimensions from the input system B, and from the CAD system D, take the rotor and cabin dimensions. , and the 81 image value of the gap between them are manually calculated and stored in the dimension management file 31. From the difference between the illumination values of the rotor dimension and the cabin dimension,
[] - Find the gap between the light and the passenger compartment as a training wheel. The 1t111 value of this gap is stored in the meme size management file 31. Dimension management system C compares the gap measurement 1- obtained as above with the gap li1 self-value input from the CAD system [), and determines which is outside the allowable range (rF dimension range). It is determined whether the rotor deflection is taken into account or not. If the 81 measured value of the gap is outside the allowable range, the dimension management system 0 records and outputs the 81 measured value in an output format that can be identified.

That is, the dimension management system C displays the 81 measured values of the gap described above on the display screen of the CRT 32, for example, in a flashing manner, and also attaches a specific mark, for example, symbol 1, to the printer 33.
Let me print it out. The above also applies to the measured values of the rotor dimension from the rotor dimension measurement/input system A and the measured values of the vehicle interior dimension from the vehicle interior dimension measurement/input system B.

Furthermore, the above-mentioned display of one measured value (blinking display in this example) is also performed on the CRT terminal 51 of the terminal device 1E. On the other hand, if the measured value is within the allowable range, the measured value is displayed as is or printed out. Therefore, the person in charge of management must check whether the measured value on the display screen -F of the CRT 32 is flashing or not, and whether or not the symbol * is attached to the 11 measured values recorded on the printer paper from the printer 33. This allows you to recognize whether each measured value is outside the allowable range.

The printout results from the printer 33 are saved as official records and submitted to the customer.

In addition, in the above embodiment, when displaying a measured value outside the allowable range, it was explained that the measurement value blinks, but instead of the blinking display, a symbol such as * (of course not limited to *) may be used. A specific mark may also be attached.
