System Introduction

The alkali dosing and dosing device automatically detects the pH value of the measured liquid through the industrial pH meter controller, and converts it into a current signal by setting the control range and outputs it to the automatic dosing metering pump. and output frequency range) automatically adjust the dosing amount of the metering pump through the received signal.

The PH automatic adjustment and dosing system has a wide range of applications in water treatment in various industrial environments. In any aqueous solution, hydrogen ions and hydroxide ions are a fixed value, which is called the ion product constant of water. Adjusting the PH value is to achieve the purpose of ultimately changing the water quality by adjusting the content of two ions in the water.

How it works

First, the pH value of the liquid in the neutralization tank or chemical reaction kettle is detected by the pH sensor, and transmitted to the industrial pH meter, and then according to the requirements of the production process, the high and low control points are set on the industrial pH meter, and the industrial pH meter will The input pH signal is compared with the high and low set values, and then the switch signal or proportional control signal is output to the control box, and the control box adjusts and controls the metering pump to add acid or lye. The system does not require personnel to operate and is automatically controlled, thereby greatly improving the accuracy and work efficiency of dosing, and ensuring the stability of the production process and the safety of personnel.

The PH automatic adjustment and dosing system firstly sets the PH value required by the treated water on the industrial PH meter, the metering pump starts to work to add the chemical liquid, the PH value in the water is detected by the industrial PH meter, and the industrial PH meter controls the table. displayed in. The industrial pH meter control meter automatically compares the measured value to the set value. If the measured value is different from the set value, control the start and stop of the metering pump, so that the PH value of the water can be automatically controlled to the set value.
