AI Technical Summary

Technical Problem

When cleaning the water pipes of central air conditioning systems with high-pressure pulse cleaning, the outer wall of the pipe bends suffers severe wear due to the centrifugal acceleration of magnetite particles. Existing technologies cannot effectively solve this problem and are costly. Furthermore, traditional methods affect cleaning efficiency or require permanent modifications.

Method used

A movable electromagnetic coil array and an eddy current buffer guide are used to control the movement trajectory of magnetite particles and reduce their kinetic energy through magnetic field control. Combined with a pulse synchronization controller, the magnetic field strength and time are precisely adjusted to prevent particles from impacting the outer wall of the bend.

Benefits of technology

It significantly reduces wear on the outer wall of pipe elbows by 90%, maintains cleaning efficiency, reduces system costs, requires no permanent modification, and is suitable for central air conditioning water pipes of various diameters and materials.
