AI Technical Summary
⚠Technical Problem
The existing water pump cutting device has insufficient cutting capacity when cutting fibrous debris, which causes the debris to become entangled, block the water pump inlet, and affect the operation of the equipment.
⚗Method used
In the cutting assembly of the water pump, based on the combination of planar cutting through and planar cutting groove, an axial cutting through and axial cutting groove are added to form a combined cutting structure, forming circumferential and axial cutting, ensuring that fibrous debris is completely cut off.
🎯Benefits of technology
Enhanced cutting capabilities prevent fibrous debris from tangling, ensuring normal pump operation and preventing blockages and motor stall.
