Introduction to the installation process of centrifugal pumps
Thread Content
1. Construct a cement foundation and lay the cable wires. 1. Leave bolt holes for the foot bolts; 2. Mark the reference line for the foundation; 3. Place the pump base on the foundation after inserting the foot bolts (aligning it with the foundation’s reference line); 4. Level the flange and align the coupling, then grout the foot bolts; 5. Level the flange and align the coupling, then grout the base; 6. Weld the pipelines (install blind flanges at the inlet and outlet); 7. Connect the power cables; 8. Test the motor: first measure the resistance and check for three-phase balance. Another no-load test: parameters such as rotation direction, current, vibration, temperature rise, and noise. 9. Cleaning of pipelines: acid cleaning, water flushing, alkali cleaning, water washing, gas purging, and airtightness testing. 10. Lubrication of the bearing housing. 11. Water test of the individual unit. 12. Water-based commissioning. 13. Commencing production with feedstock. Each process has detailed and strict requirements. There must be work records and supervisor’s acceptance signatures for the entire process.
•Process of installing a centrifugal pump: 1. Foundation preparation, inspection of foundation dimensions, and arrangement of shims; 2. Disassembly, inspection, cleaning, and adjustment of the centrifugal pump. III. Assembly of the centrifugal pump. IV. The centrifugal pump base plate, water pump, and motor are in place. V. Coupling connection and centering. VI. Trial operation.
Nowadays, ordinary pumps do not need to be disassembled for inspection and reassembled. Additionally, the motor trial run should be treated as a separate procedure.
I see now; it turns out that installing a centrifuge requires so many procedures
