AI Technical Summary

Technical Problem

When the assembled high-pressure cylinders in the turbine factory are transported to on-site installation, an effective method is needed to ensure the accuracy of the dynamic and static gaps inside the high-pressure cylinder. The existing methods have problems of vibration and small operating space, which affects the accuracy of measurement.

Method used

An integrally supplied high-pressure cylinder is designed, including a first positioning block and a second positioning block at the ends of the cylinder block. These positioning blocks provide a positioning surface and perform clearance measurements with an inner diameter micrometer to ensure the accuracy of the measurement.

Benefits of technology

By using positioning blocks and micrometers, the dynamic and static position changes of the high-pressure cylinder can be accurately measured, the accuracy of gap measurement is improved, inaccurate adjustment caused by vibration and operating errors is avoided, and the stable operation of the high-pressure cylinder of the turbine is ensured.
