For the spiral winding variable frequency electromagnetic water processor

magnetic induction intensity of water in processing cavity and induced current were analyzed with ANSYS simulation software. The inner relationship of magnetic induction intensity and induced current work with excitation signal frequency was studied. Using an online evaluation test bench for electromagnetic scale inhibition

the influence of spiral winding processing cavity frequency on scale inhibition of hard water circulation heat transfer experiment pipe was observed

and the ideal scale inhibition frequency was determined. Under this experimental condition

the frequency near the line frequency had longer scale induction period and stronger scale inhibition effect

and anti-scaling efficiency was the best.
