In the rubber rotor pump injection process, the treatment of the rotor metal skeleton is particularly important, which determines the stability of the rotor in the later use and the self-priming pressure that can be achieved. The main purpose of processing the metal skeleton in the glue injection process is to increase its adhesion. The main steps are as follows:
1. High temperature degreasing of the processed metal framework;
2. Sand blast on the surface in contact with the rotor;
3. Use a volatile solvent to clean the surface of the metal skeleton;
4. Glue after the metal frame has cooled, and then proceed to the next step after cooling.
In the overall processing of the metal skeleton, more details are required, and reasonable time control is especially important.
