AI Technical Summary

Technical Problem

In the existing technology, the installation process of the pump rotor relies on experienced assembly workers, and it is difficult to achieve high-precision and reliable assembly, resulting in a high failure rate of liquid rocket engines.

Method used

The main shaft is fixed by a top shaft fixture and a centrifugal wheel clamping anti-rotation fixture. The top shaft fixture, which consists of a limit plate, a top shaft block, and an involute spline, is used to fix the main shaft. Combined with the centrifugal wheel clamping parts and the centrifugal wheel adjusting pad made of rubber, the main shaft and the high-speed centrifugal wheel are accurately installed and anti-rotated.

Benefits of technology

It improves the installation accuracy and reliability of the pump rotor, reduces the failure rate of liquid rocket engines, simplifies the operation process, and improves assembly efficiency and versatility.
