The stuffing box is installed at the shaft seal section of the slurry pump, located at the connection between the pump body and the pump shaft. Its primary function is to prevent slurry leakage along the shaft, provide effective sealing protection, and ensure stable and reliable pump operation under abrasive slurry conditions.
As a critical sealing component of the 3/2C-AH slurry pump, the stuffing box helps protect the pump shaft and pump casing, improves sealing efficiency, and significantly extends the service life of the pump.
The 3/2C-AH stuffing box works together with packing, lantern rings, shaft sleeves, and gland assemblies to form a complete packing seal system. By maintaining proper packing compression and controlled leakage, it ensures effective sealing while allowing necessary lubrication and cooling of the shaft.
Manufactured from high-strength cast materials, the stuffing box features excellent structural integrity and wear resistance. Precision-machined internal surfaces ensure accurate alignment with the shaft sleeve, reducing eccentric wear and improving overall sealing performance, even in high-solids and high-wear slurry applications.
Proper Packing Installation: Packing should be installed evenly in layers, avoiding over-tightening or looseness to prevent leakage or shaft wear.
Adjust Packing Pressure: Apply sufficient pressure to create an effective seal without excessive friction. Periodic adjustment is recommended.
Lubrication and Cooling: Ensure adequate lubrication or flushing water to reduce friction and prevent overheating.
Even Bolt Tightening: Tighten gland bolts evenly in a crisscross pattern using appropriate torque.
Check Shaft Alignment: Proper shaft alignment is essential to minimize wear and extend component life.
