A dosing device is a complete set of equipment that integrates dosing, stirring, liquid transportation, and automatic control. It is used in circulating water systems that require the addition of corrosion inhibitors, scale inhibitors, and bactericides to accurately dosing and metering water treatment agents.In the process of water supply and drainage treatment, various chemical agents are often added for scale inhibition, sterilization, algae removal, coagulation, and flocculation to achieve the purpose of purifying water. These drugs have solid particles and liquids, and must be dissolved, diluted, and quantitatively added according to the ratio during the dosing process to achieve good results. Therefore, the dissolving drug dosing device is one of the commonly used equipment in water treatment engineering.
Fully automatic dosing deviceComposed of metering pumps, medicine barrels, mixers, brackets, electric control cabinets, etc., it is an advanced automatic dosing equipment for water treatment systems developed by our company based on the introduction of foreign microcomputer metering pumps and combined with the actual situation of domestic water systemsWorking principleThe dosing pump motor is driven by an AC frequency converter to inject medication into the liquid. The concentration of the medication is detected by a detector, which inputs an electrical signal proportional to the concentration to the regulator and compares it with the set value to obtain a deviation signal. The regulator compares and integrates the deviation signal according to the process requirements, and sends the calculation result signal to the frequency converter. The frequency converter changes the frequency of the motor's working power supply according to the adjustment signal output by the regulator, causing the motor speed to change and the concentration of the medication in the injected liquid to be controlled within a reasonable range.
scope of application:Industrial cooling circulating water system, air conditioning refrigeration system, heat exchange system, hot water boiler system, production and domestic hot water supply system.
Performance characteristics:1. High degree of automation, uniform and accurate dosing. By using a microcomputer dosing controller (metering pump) to control the dosage, in addition to regularly adding dosing agents to the dissolution tank, no manual operation is required, saving a lot of manpower and making the dosing amount more accurate.2. Long service life. All parts in contact with the medicinal solution are made of PE engineering plastic, which is resistant to strong acids, strong alkalis, and aging. The driving device does not come into direct contact with the liquid medicine, and the pump body is fully enclosed. It is injection molded in one go, and there is no problem of liquid medicine leakage.3. Users can choose from mixers according to their needs PLC、 Functions such as online monitoring of temperature, pH value, and conductivity.
