Types of automatic dosing systems:

It can be roughly divided into a unitized combined dosing device, mainly consisting of a solution tank, metering pump, filter, valve, check valve, pulse damper, water level gauge, control cabinet, etc., which are installed on a single base. The user only needs to place the combined dosing device in the dosing room, connect the dosing pipe and power supply, and then start and put it into operation. This factory-made complete set of equipment can greatly reduce the workload of design and on-site construction, and provide a reliable guarantee for the quality of the entire machine and on-site operation.

The dosing device is a complete set of equipment that injects chemical solutions into various systems according to the process flow. This device can be classified into three major categories based on the application scenarios.

1"Oilfield"Automatic dosing system. It is mainly used to inject various liquid chemicals such as flocculants, scale inhibitors, corrosion inhibitors and demulsifiers into wellheads and other systems on platforms during oil extraction.

2BoilerAutomatic dosing system. It can be used for adding ammonia and hydrazine to boiler feed water, adding ammonia and hydrazine to condensate water, adding ammonia and hydrazine for boiler protection during shutdown, and adding phosphate to steam boilers. It is mainly used in power plants and power stations.

3Water treatment dosing device. Chemicals are added to tap water, wastewater and sewage during the water treatment process. It is mainly used in processes related to water supply and drainage treatment, environmental protection, etc. Such as waterworks, hotels, restaurants, swimming pools, sewage treatment plants, etc.

Automatic dosing systemIt mainly uses metering pumps as the dosing equipment, and includes a solution tank, a stirrer,

Level gauges, valves, check valves, pressure gauges, filters, buffers, pipelines, valves, bases, ladders, automatic monitoring systems, power control systems, etc. are assembled on a common platform as required by the process flow to form a module, which is known as a skid-mounted modular unit.

It adopts an electromechanical structure form and can be classified into fixed type and mobile type (trolley type) in terms of installation. Each type of dosing device is equipped with a stirring system, a dosing system and an automatic control system. Several fixed skid-mounted units can be combined into a whole. With the addition of a frequency conversion control system, local control, remote automatic control, and mutual conversion between manual and automatic dosing can be achieved. It features a compact structure, small size, low noise, stable operation, simple installation and convenient operation and use.

Through different process designs, chemical solutions of various solids and liquids are precisely configured and then accurately added with metering pumps to meet various design requirements. Such as scale removal, deaeration, coagulation, acid addition, alkali addition, etc.

The dosing process can be operated manually or throughPCMechanical, magnetic flap level gaugePHA variety of electrical appliances and instruments such as meters, travel controllers and frequency converters make the dosing device an electromechanical product and achieve automatic control.

The dosage and pressure of chemicals can be determined by selecting the appropriate metering pump according to the requirements of the industrial process. "Traffic1L/hto8000L/h,Pressure0.1MPato25MPaSuitable products can be selected within the range.

The metering accuracy of the metering pump can be as high as±1%And it can simultaneously convey multiple media and adjust them independently.

Automatic dosing systemThe volume of the solution tank can be small0.1m3to20m3,It can be selected based on the dosage of chemicals. Depending on the different conveyed media, there are various materials available for selection, such as carbon steel (carbon steel lined with rubber), stainless steel, and non-metallic materials.PE,PVC,PP,PTFEEtc.

Performance description of the automatic dosing system

The complete set of equipment mainly includes the feeding system, the storage tank, the dosing system, the power control system, etc.

The dissolution tank is equipped with facilities necessary for automatic operation, such as a liquid level gauge, low liquid level alarm, and valves. The outer wall of the entire body is equipped with a magnetic flap level gauge to monitor the liquid level inside the bucket in real time. There is a feed port and a spare port on the top of the entire body. On the side of the bucket body, there are a discharge port, a sewage port, an overflow port, a level gauge interface and corresponding matching doors. When the liquid level in the bucket is lower than the set low liquid level value, the alarm system will be automatically activated and the dosing pump will stop.

The dosing system includes centrifugal pumps, electromagnetic flowmeters and related valves, etc.

Functional features

With system design as the main body, it overcomes the defect of poor systematicness existing in traditional products that take a single device or component as the design main body.

Absorbing the essence of domestic and foreign drug application technologies, with a brand-new design concept, the process is further optimized.

The product structure is modularly designed and combined, allowing for convenient expansion of capabilities and functions.

It can flexibly configure the best solution according to different water qualities and different requirements of users.

A wide range of domestic and foreign brands, different materials and various grades of equipment and components are available for users to choose from freely.

Choose from various control methods such as manual and automatic to meet different control requirements.
