The intelligent automatic dosing machine uses sensor signals to control the working process of the dosing pump. This control method requires the use of pH meter, conductivity meter and other testing instruments and corresponding sensors. The control parameters (pH value or conductivity) must be set according to the operation of the system. If the system encounters the following situations during operation, the automatic dosing device will start: If the pH value is lower than or higher than the set value. The pH value is slightly lower, indicating that the acidity is too strong and the system has Corrosion tendency; a higher pH value indicates that the alkalinity is too strong and the system has a tendency to scale. At this time, the detection instrument will send this signal to the control technology, and the control technology will then output a command to the designated metering pump to open the dosing system. To adjust the pH value, after the pH value returns to normal, the metering pump is turned off. If the conductivity is higher than the preset value, it means that the salinity in the system exceeds the standard and there is a tendency for corrosion and scaling. At this time, the monitor will send this signal to Control technology, the control technology then outputs a command to the sewage solenoid valve, causing the solenoid valve to open to drain water. After the conductivity returns to normal, the solenoid valve closes. Then the metering pump opens to add medicine to make up for the medicine lost in the sewage discharge, and maintain the dosage of the system. At normal levels, add a specified time to shut down the metering pump.
Automatic dosing machines often need to continuously and automatically inject a certain type of liquid into another liquid to become a mixed liquid in the fields of electric power, crude oil, chemical industry, metallurgical industry, environmental protection engineering, water treatment, etc., or to make the added medicine Chemically reacts with certain components present in the liquid to achieve the expected process requirements. In order to achieve better results, the amount of added chemicals is automatically tracked and adjusted to control the dosing rate under load changes. Therefore, in In this kind of equipment, Yantai Ruixing uses cutting-edge intelligent automatic control methods to control the amount of dosing. The BJF intelligent automatic dosing device has a compact structure and is easy to install. It mainly consists of a metering box (drug storage tank), metering It is composed of pump (dosing pump), control system, connecting pipelines, etc.
In addition to part of the dosing pipeline, sampling pipeline and dosing concentration detection instrument, the automatic dosing machine is generally installed centrally in a dosing room. The automatic dosing equipment combines the metering box, metering pump, control The system is integrated, that is, installed on a base. The manufacturer carries out equipment purchase, manufacturing, assembly, adjustment, and trial operation. The customer only needs to place the intelligent automatic dosing device in the dosing room and then The outlet of the metering pump is connected to the dosing pipeline, the inlet and outlet of the metering box and the water inlet, etc., and then the power supply and measuring instrument signal of the control box are sent to the control box to run and put into operation. This can greatly reduce the workload of on-site operations. It avoids errors and omissions caused by various middlemen, effectively guarantees the construction period and project construction quality, and reduces customers' inconvenience and losses.
