Abstract

The invention relates to the construction of pressure supplement equipment for separating uranium isotopes by centrifugal method, in particular to a method for converting decommissioned compressors into centrifugal pressure supplement machines by using diffusion method. The decommissioned compressor for separation of uranium isotopes by diffusion method is removed from the diffuser vane to reduce the compression ratio, its internal and external structure and interface are modified to meet the requirements of the centrifugal process, and technical transformation methods such as replacing the bearing oiler are used to make it suitable for Section make-up presses and stream make-up presses in cascades for separation of uranium isotopes by centrifugation. After the reformation, the electromechanical test and the parameter measurement during the operation of the production system show that its main performance indicators have reached the design requirements and meet the requirements of the centrifugal cascade production process. Restructuring 100 units can save foreign exchange equivalent to 15 million yuan, and the method of reorganization is simple and easy.

Description

The method of converting decommissioned compressor into centrifugal pressure supplementary machine by diffusion method in the production of separated uranium isotope Technical field: The present invention relates to the construction of a kind of centrifugal separation uranium isotope pressurization equipment, be specifically related to a kind of In isotope production, the decommissioned compressor is transformed into a centrifugal pressure supplementing machine by diffusion method. Background technique: At present, be used for the pressurization and delivery of uranium hexafluoride (UF6) diffusion gas in the uranium isotope production technique of diffusion The delivery compressor, namely the OK-19 compressor, was imported from the former Soviet Union in the 1950s. In my country, with the separation of uranium isotopes With the development of production technology, the diffusion method is being replaced by the centrifugal method. The original OK-19 compressor has a hi...
