Introduction to Dosing Device Products

The dosing device is mainly composed of a metering pump as the main dosing equipment, which assembles the dissolving tank, mixer, dosing device level gauge, safety valve, check valve, pressure gauge, filter, buffer, pipeline, valve, base, escalator, automatic monitoring system, power control system, etc. on a common platform according to the process requirements, forming a module called a modular combination unit (referred to as "pry body"). The following is a detailed introduction to the dosing device product:

1、 Working principle

The dosing device can accurately prepare solutions of various solid and liquid chemical drugs according to a carefully planned process flow. Specifically, the medication will be pre prepared in the metering box (medication storage tank) according to the predetermined ratio and requirements. Subsequently, the prepared solution is added to the liquid to be treated through accurate operation of the metering pump (dosing pump). This process can be carried out manually or connected to various electrical appliances and instruments such as PCs, magnetic flap level gauges, pH gauges, stroke controllers, frequency converters, etc., to achieve automated control.

2、 Product classification

Quantitative dosing device: capable of accurately controlling the dosage of medication, widely used in situations where precise control of medication dosage is required. By using a metering pump or other accurate metering equipment, this device can achieve quantitative dosing of drugs, with advantages such as high dosing accuracy, good stability, and high degree of automation.

Timing and quantitative dosing device: On the basis of the quantitative dosing device, a timing function has been added, which can automatically dosing according to the preset time interval and dosage of the drug. This device is widely used in situations where dosing needs to be done according to a certain time and dosage, such as regular dosing in water treatment plants and timed injection in oil field exploitation.

Dry powder dosing device: mainly used for the dosing of solid drugs, which is uniformly and continuously added to water through a dry powder dosing machine. This device is suitable for the dissolution and addition process of solid drugs, and has the advantages of uniform addition, fast dissolution speed, and simple operation.

Automatic dosing device: integrates many components such as solution tank, mixing tank, metering pump, liquid level gauge, electric control cabinet, pipeline, valve, etc., with a compact structure and easy installation. This device has the characteristic of high automation, which can set the automatic dosing cycle, dosing amount, dosing time and frequency according to the system operation needs.

Special purpose dosing device: such as dosing device for circulating cooling water system, etc.

3、 Application Fields

Dosing devices are widely used in multiple fields, including but not limited to:

Boiler water treatment system, circulating cooling system, central air conditioning circulating water system, raw water pretreatment and wastewater treatment system in the thermal power generation industry.

Boiler water treatment systems, circulating cooling systems, chemical additive dosing systems, and wastewater treatment and disinfection systems in industries such as petroleum and chemical engineering.

Disinfection of municipal water supply, swimming pools, water plants, sewage treatment, and building domestic water.

Disinfection of industrial circulating water and industrial wastewater treatment.

4、 Product Features

Accurate configuration: Able to accurately configure chemical solutions according to specific process requirements, ensuring that the concentration and dosage of the chemicals meet preset standards, and achieving diverse treatment effects such as descaling, deoxygenation, coagulation, acid addition, and alkali addition.

Flexible and versatile: It can play its role in multiple fields, whether it is heavy industries such as electricity, petroleum, and chemical, or light industries such as environmental engineering and water treatment, it can cope with them with ease. At the same time, the volume of the solution tank can be flexibly adjusted between 1m ³ and 20m ³ according to the actual dosage, to adapt to various complex usage environments and requirements.

Highly automated: By introducing advanced automatic control technology, the dosing device can track changes in industrial processes in real time and automatically adjust the dosing speed without frequent manual intervention, which not only improves work efficiency but also reduces human errors.

5、 Installation and maintenance

Installation points: The equipment should be installed in a stable, dry, and well ventilated environment to ensure stable operation and extend its service life. At the same time, the equipment space should be reasonably arranged according to the selected model and specifications to facilitate daily operation and maintenance.

Precautions for use: Before use, carefully check the integrity of all components of the equipment, including metering pumps, valves, and pipelines. Set appropriate dosing amount and dosing pressure parameters according to actual process requirements. During the dosing process, the remaining amount of medication should be regularly checked and replenished in a timely manner. Continuous monitoring of equipment operation status is crucial. Once any abnormal signs are detected, such as leaks, pressure fluctuations, etc., it is necessary to immediately shut down and take necessary maintenance measures.

In summary, dosing devices play an important role in multiple fields due to their effective and accurate performance. To ensure its long-term stable operation and effective performance, users should strictly follow the user manual for operation and regularly check the equipment performance for necessary maintenance and upkeep.
