AI Technical Summary

Technical Problem

In the existing technology, checking the sealing performance of the lubricating oil chamber of a gas turbine using a feeler gauge is cumbersome and difficult to perform in a confined space, and it is impossible to test the sealing performance of all sealing parts at once.

Method used

Design a tool kit for inspecting the sealing of a gas turbine lubricating oil cavity, including components such as a front sealing ring, a front fixing ring, a rear sealing ring, a rear fixing ring, a plug, and bolts. These components are used to seal the lubricating oil cavity, and the sealing performance of the lubricating oil cavity is verified by applying pressure.

Benefits of technology

It enables a one-time sealing test of all sealing parts of the lubricating oil cavity, making the observation of oil seepage and leakage more accurate and intuitive, and improving the testing efficiency and accuracy.

Abstract

The application discloses a gas turbine oil cavity sealing inspection tool set, which comprises a front sealing ring, a four-support-point oil ring sealing connection of a gas turbine, a front fixed ring, a four-support-point bearing stop boss sealing connection, a rear sealing ring, a five-support-point sealing runway sealing connection, an oil inlet and an oil outlet for respectively communicating with an oil outlet pipe and an oil inlet pipe of an oil pressure device, a rear fixed ring, a five-support-point bearing stop boss sealing connection of a low-pressure turbine shaft, at least one bolt, at least one through hole of the rear sealing ring, at least one threaded hole of the front sealing ring, the bolt passing through the through hole and being screwed into the threaded hole corresponding to the through hole, and a plurality of plugs for sealing the oil holes. Compared with using a plug gauge to screen the gap size of each sealing part of the oil cavity, the application can test all the sealing parts of the oil cavity at one time, and it is more accurate and intuitive to observe whether oil seeps or leaks.
