    摘要: This automatic admixtrue dosing and pH value control batch dyeing system is comprised of a pH value gauge, a thermometrer, a pump for adding chemicals, a drain valve, a chemical tank, a continuous action depth gauge, a mixing valve, and a chemical input valve. The controller is designed to proceed according to several chemical graphs located inside the controller. The user, depending on the requirment of chemical dosing and pH value control, sets the time for inputting chemical and a predetermined pH value. When this is done, the controller, according to the selected chemical graphs and target pH values, operates the chemical pump, the mixing valve, and the chemical dosing valve. The chemical module flow into action, and the dye liquor in the chemical tank flow into the dye machine. The depth gauge, the pH gauge and the thermometer measurs the volume of liquid in the chemical tank, and the pH value and temperature of the dye liquid in the dye machine. The information is individually fed back to the controller which can automatically monitor the dye liquor pH value and chemical condition. The final stage consists of the automatic control of the chemical volume and pH value.
