AI Technical Summary

Technical Problem

In the process of oil exploration and development, high-temperature hydraulic power generators are limited in output power due to the limited diameter of the generator body and the high temperature and high pressure environment, and heat dissipation is also difficult.

Method used

The generator adopts a combined structure of impact-resistant permanent magnet and DC coil magnetic field. The combined magnetic shaft of the stator assembly and integrated generator rotor magnet is arranged inside the pressure shell. It combines the permanent magnet power generation unit and the DC coil magnetic field power generation unit, and improves the impact resistance and output power of the structure through multi-bearing arrangement.

Benefits of technology

It achieves high output power in a limited space, has a compact structure, is easy to disassemble and assemble, and is convenient to maintain. It can adapt to a wider range of power source liquid displacement and speed, and improves the reliability and shock resistance of the generator.
