It is expelled in material-output tank.
Peristaltic pump is also peristaltic pump, and it is just as piece hydraulically full flexible pipe of finger clamp is with finger forward slip, and pipe is interior
Liquid is moved forward, and peristaltic pump is also this principle, simply instead of finger by electric drive roller, by the elasticity conveying to pump
Flexible pipe is alternately extruded and discharged and pumps fluid, just as two finger pinching pipes, with the movement of finger, shape in pipe
Into negative pressure, liquid is flowed therewith, and pump line (i.e. peristaltic tube) is placed on the pipe bed of rotor and pump case component, and its effect is by pump line
Locking (is squeezed flat), and the roller on rotor rolls across pump line successively, and the fluid compression in pipe is gone out, and pump line recovers former after roller grinds
Shape, forms vacuum, and thus fluid suction below can be come in, and a fluid " pillow " is formed between roller, so works as wriggling
The delivery pipe of pump roller period of the day from 11 p.m. to 1 a.m conveying liquid direction of advance bears malleation, and during wriggling pump work behind liquid in delivery pipe inhaled
Go out, delivery pipe bears negative pressure, when delivery pipe is soft material pipe, can be become big by the pipe of malleation, can quilt by the pipe of negative pressure
Inhale flat, because peristaltic pump is to extrude flexible pipe liquid to produce extruding force to convey liquid, pump can operationally produce a shakiness
Fixed pulse, this pulse can cause the change of liquid in pipe pressure, also flexible pipe can be caused to expand and shunk, and this action is just
It is our needs, the generation of dirt will be damaged in flexible pipe expansion and contraction, but this pulse can not be single
Ground reaches the purpose of scale removal, this be due to pulse be it is instantaneous quickly 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, cannot 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 cannot shrink.
Compared with prior art, inventor makes the side of flexible pipe deformation using another kind to the present invention on the basis of existing structure
Formula carries out scale removal, saves influence of the valve to scale removal, can not stop pump liquid with stylish descaling method and realize On Line Foul Removing Technology.
This method relatively before way, deforming hard tube inner flexible tube only needs smaller pressure, and this pressure is negative pressure, and this negative
Pressure is the negative pressure that peristaltic pump extruding is produced, and the pressure demand to flexible pipe is small, thus the service life of flexible pipe can be longer, and cost
It is lower.Inner-layer hose also need to be only changed when piping failure, outer layer hard tube may continue to use, so also reduce production institute
Cost use.The blast pipe on hard tube is become simultaneously the leakage liquid centralized collection pipe when the flexible pipe breakage after, it is to avoid leakage pollution.
