Introduction

Laundry dosing device, dosing equipment, dosing device, dosing system, automatic dosing, automatic dosing device, automatic dosing equipment, automatic dosing system.In order to achieve the best results, under the condition of changing working conditions, the dosage of the added chemical agent is automatically tracked and adjusted to control the dosing speed. Therefore, in this device, the ALFT intelligent automatic dosing equipment has a simple structure and is convenient to install.

Technical Parameters

Applicable system pressure: working power supply: 220V/50Hz

Working environment: temperature 5～45℃, humidity ≤85%

Automatic dosing equipment

Time program control is adopted. This control method does not require instrument support. First, set the automatic dosing cycle, dosing amount, dosing time, and dosing frequency according to the operation of the system. In the subsequent operation of the system, the metering pump will automatically turn on and dosing at the dosing cycle, and the metering pump will be turned off after the specified time; at the drain cycle, the metering pump will stop dosing, and after the specified time, the metering pump will continue to open , To replenish the medicament lost by sewage, maintain the medicament content of the system at a normal level, and close the metering pump when added to the specified time.

Intelligent dosing equipment

The intelligent dosing equipment adopts the working process of sensor signal control. This control method requires monitoring instruments such as pH meter, conductivity meter and corresponding sensors. First, set the limit value of the control parameter (pH value or conductivity value) according to the operation of the system. The dosing device will start to work if the following conditions occur during the operation of the system: if the pH value is lower or higher than the set value. A low pH value indicates that the acidity is too strong and the system has a tendency to corrode; a high pH value indicates that the alkalinity is too strong and the system has a tendency to scale. At this time, the detection instrument will feed back this signal to the control system, and the control system will then output instructions to the designated metering pump to open the dosing system to adjust the pH value, and turn it off after the pH value returns to normal. If the conductivity is higher than the set value, it indicates that the salt content of the system exceeds the standard, and there is a tendency for corrosion and scaling. At this time, the monitoring instrument will feed back this signal to the control system, and the control system will output a command to the sewage solenoid valve to open the solenoid valve to drain the water. After the conductance returns to normal, the solenoid valve closes. Then the metering pump is turned on to dosing to replenish the medicament lost by the sewage, and the system's drug content is maintained at a normal level. The metering pump is turned off after the prescribed time.

In the fields of electric power, petroleum, chemical industry, metallurgical industry, environmental engineering, water treatment, etc., it is often necessary to continuously and automatically inject a certain liquid into another liquid to become a mixed liquid, or to make the added medicine and certain liquid in the liquid. The chemical reaction of these components occurs in order to meet the expected process requirements. It is mainly composed of metering box (medicine storage tank), metering pump (dosing pump), automatic control system, connecting pipelines, etc. Except for some dosing pipelines, sampling pipelines and dosing concentration detection instruments, these equipments are generally installed in a dosing room. The automatic dosing device integrates the metering box, metering pump, and automatic control system, namely installation On a base. After the manufacturer completes the equipment purchase, manufacturing, assembly, debugging, and trial operation, the user only needs to place the intelligent automatic dosing device in the dosing room, and connect the metering pump outlet to the dosing pipeline, the metering box inlet and outlet, and the water inlet pipe. Wait for the connection, and send the control cabinet power supply and detection instrument signals to the control cabinet to start and put into operation. This can greatly reduce the workload of on-site construction, avoid many errors caused by intermediate links, effectively ensure the construction period and project quality, and reduce the trouble and loss of users.
