AI Technical Summary
The existing slurry pump stuffing box is an integral structure, which requires the removal of the flow passage parts when replacing it, increasing the workload and downtime. This is especially difficult for large slurry pumps, affecting the continuity of production.
The packing box adopts a split-type packing seal box structure, dividing the packing box into two parts connected by fasteners. This allows for the replacement of the packing box separately, avoiding the removal of flow-through components. Combined with the design of sealing grooves and lifting holes, the maintenance process is simplified.
This allows for the replacement of the stuffing box without removing the flow-through components, reducing workload, shortening downtime, improving sealing performance and equipment stability, reducing reliance on manpower and equipment, and ensuring production continuity.
