Fluid product, e.g. colorant, proportioning device, has frequency changer controlling motor that drives main shaft which drives pumps and drives pinions through belt permitting to rotate stirring blades while driving pumps

摘要

Fluid product proportioning device has a frequency changer (9) controlled by an automaton (10) which calibrates fluid product to be proportionated, so that weight/volume values of the product are converted into milliseconds. The changer controls a motor (8) that drives a main shaft (12) which drives pumps (6) and drives pinions (4) through a belt (5) permitting to rotate stirring blades (2) situated inside reservoirs (1) while driving the pumps.
