METHOD OF MAKING PROGRESSING CAVITY PUMPING SYSTEMS |
摘要 |
<p>A progressing cavity rotor facilitates pumping applications in progressing cavity pumping systems by ensuring a desired shape of the rotor. A resilient layer is placed over a rotor core to create a composite progressing cavity pump system rotor. Generally, the rotor core is formed from a harder material, such as a metallic material. Additionally, the composite rotor is placed in a mold and subjected to a molding treatment designed to enhance bonding of the resilient layer and formation of a desired exterior surface shape of the resilient layer.</p> |
