AI Technical Summary

Technical Problem

Oil film buildup in existing condensers requires regular maintenance, but it is difficult to easily remove the connecting pipes for maintenance and replacement.

Method used

The condenser is designed with a built-in oil separator, including an oil separator and a rotating assembly. It is separated from the main oil return pipe by a rotating pipe, which facilitates the maintenance of the connecting pipe. At the same time, the use of limit blocks and sealing rings improves the sealing performance and facilitates maintenance.

Benefits of technology

It enables convenient maintenance of the connecting pipes, improves the working efficiency of the condenser, maintains good sealing performance under high pressure and high temperature conditions, and facilitates the inspection and replacement of the sealing rings.
