Ground reaches the purpose of scale removal, and this is due to that pulse is instantaneous quick, and the growth of dirt is relatively slow, fast one day growth 1mm,
The negative pressure contrast of pulses generation less, can not form flexible pipe significantly expansion and reach scale removal with shrinking, when peristaltic pump conveying simultaneously
It is relative expansion in a steady pressure bottom hose, bore becomes big, without shrinking, the dirt of growth can not be thus produced
Raw destruction, can not lean on small expansion and contraction to carry out scale removal when dirt grows into certain thickness and forms certain intensity.
Thus larger external force must be imposed to deform flexible pipe, and completely deformed, once there is a point not deform, dirt will
Continued propagation, growing big dirt can be powerful crowded broken to that can not shrink.
