2021-07-06View Original

Thread Content

Single-screw pumps are also known as progressive cavity screw pumps abroad. So what are their components (progressive cavity pump parts)? In fact, the simple classifications are as follows: 1. Screw pump stator 2. Screw pump rotor (some manufacturers refer to it as the screw) 3. Screw pump connecting rod (also known as the intermediate shaft) 4. Drive shaft 5. Universal joint assembly (there are two common types: pin-type universal joints and cross-linked universal joints) 6. Sealing (mechanical seal or packing seal) 7. Pump body – rarely breaks 8. Bearing housing – rarely breaks, etc. The most common ones are 1 to 6 items. Feel free to add more. . . .
