How to Assembly and Disassembly the Vertical Turbine Pump?
Vertical turbine pumps play a critical role in deep well applications, especially where water needs to be lifted from dozens of meters underground. Unlike horizontal or inline pumps that can be hoisted and serviced as a single unit, vertical turbine pumps are assembled and disassembled section by section due to their deep well installation.
Assembly Process of Vertical Turbine Pump
| Step | Operation Stage | Key Actions | Technical Notes |
| 1 | Pump Shaft Installation | Insert pump shaft into water intake pipe; install gasket and mounting nut at inlet bottom | Shaft should protrude 130–150 mm from lower flange (smaller pumps require larger protrusion) |
| 2 | Conical Sleeve & Impeller Installation | Slide conical sleeve onto shaft until it contacts gasket; install impeller and lock nut | Ensure firm seating of conical sleeve before tightening |
| 3 | Intermediate Stage Assembly | Install impeller and casing stage by stage; measure rotor axial displacement | Ideal axial displacement: 6–10 mm; if < 4 mm, reassembly is required |
| 4 | Final Axial Adjustment | Turn adjusting nut to lightly contact drive disc, then rotate 1–1.67 turns (1–5/3) | Provides correct axial clearance between impellers and bowl assembly |
Disassembly Procedure for Vertical Turbine Pump
| Step | Disassembly Stage | Key Actions | Precautions |
| 1 | Initial Lifting | Unbolt pump base; lift pump vertically using tripod and manual hoist | Keep pump vertical to avoid shaft bending |
| 2 | Load Transfer with Clamping Plates | Install clamping plates on discharge column; remove pump base after load is supported | Ensure plates are securely fastened before removing base |
| 3 | Section-by-Section Dismantling | Lift pump, clamp next section, remove exposed section; repeat | Disassemble sequentially to prevent component damage |
| 4 | Impeller Removal | Use custom removal sleeve on small end of conical sleeve; tap to release impeller | Apply force evenly to avoid damaging impeller or sleeve |
Conclusion
Correct assembly and disassembly of a vertical turbine pump are vital to ensuring its performance and reliability, especially in deep well applications. Following a precise and safe procedure reduces mechanical failures, ensures proper alignment, and prolongs operational lifespan.
