AI Technical Summary

Technical Problem

Existing technologies cannot effectively utilize the potential energy of high-level slurry for clean water transportation. Furthermore, traditional equipment is inefficient, structurally redundant, and costly in the transportation of high-concentration, highly abrasive slurries, and cannot meet the needs of high-pressure or long-distance water transportation.

Method used

The hydraulic diaphragm pump is driven by the potential energy of the slurry in a coaxial double-cylinder structure, eliminating the need for a diaphragm tank at the delivery end. The flow rate and pressure are actively matched by the cylinder diameter ratio design of the drive cylinder and the water cylinder. Clean water enters the water cylinder directly and is driven by the potential energy of the high-level slurry.

Benefits of technology

The equipment structure has been simplified, manufacturing costs and maintenance difficulty have been reduced, energy utilization and equipment lifespan have been improved, and efficient and stable clean water transportation has been achieved.
