AI Technical Summary

Technical Problem

Existing slurry pump wear testing devices cannot achieve real-time adjustment and control of slurry concentration, and the data acquisition accuracy and real-time performance are insufficient, making it impossible to achieve real-time correlation between the wear process and pump operating parameters.

Method used

A solid-liquid two-phase flow centrifugal pump wear test device was designed. It adopts a symmetrical dual-circulation structure and integrates two independent test pump units and test circuits. Through the concentration adjustment pipeline system and sedimentation control mechanism, the slurry concentration can be adjusted and precisely controlled in real time. Combined with high-precision sensors and PLC data processing system, multi-dimensional operating parameters are collected synchronously in real time.

Benefits of technology

It enables rapid and precise adjustment of slurry concentration, improves data acquisition accuracy and real-time performance, and realizes real-time correlation and visualization between the wear process and pump operating parameters, significantly improving test efficiency and data comparability.
