Product details:

1、 According to the usage scenario, it can be divided into three categories:

1. Oilfield dosing device. Mainly used for injecting various chemicals such as coagulants, scale inhibitors, corrosion inhibitors, demulsifiers, etc. into the wellhead and other systems on the platform during oil extraction.

2. Boiler dosing device. It can be used for adding ammonia and hydrazine to boiler feedwater, condensate, shutdown protection, and adding phosphate to steam boilers. It is mainly used in power plants and power stations.

3. Water treatment dosing device. Add chemicals to tap water, wastewater, and sewage during the water treatment process. Mainly used for processes related to water supply and drainage treatment, environmental protection, etc. Such as waterworks, hotels, restaurants, swimming pools, sewage treatment plants, etc.

2、 Working principle

The dosing device is mainly composed of a metering pump, a dissolving tank, a stirring dosing device, a liquid level gauge, a safety valve, a check valve, a pressure gauge, a filter, a buffer, a pipeline, a valve, a base, an escalator, an automatic monitoring system, a power control system, etc., which are assembled on a common platform according to the process requirements to form a module, known as a modular combination unit.

The dosing device adopts an electromechanical integrated structure, which can be divided into fixed and mobile (cart type) installation. Each form of dosing device is equipped with a mixing system, dosing system, and automatic control system. Several fixed pry mounts can be combined into a whole, coupled with a variable frequency control system, which can achieve local control, remote automatic control, and manual and automatic mutual conversion of dosing. It has the advantages of compact structure, small volume, low noise, smooth operation, simple installation, and easy operation and use.

The dosing device precisely prepares solutions of various solid and liquid chemicals through different process designs, and then accurately adds them using a metering pump to meet various design requirements. Such as descaling, deoxygenation, coagulation, acid addition, alkali addition, etc.

The dosing process can be manually operated, or various electrical appliances and instruments such as PC, magnetic flap level gauge, pH meter, stroke controller, frequency converter, etc. can be used to make the dosing device an electromechanical integrated product and achieve automatic control.

The dosage and pressure of the dosing device can be selected according to the needs of the industrial process, and a suitable metering pump can be chosen. Suitable products can be selected for flow rates ranging from 1L/h to 8000L/h and pressures ranging from 0.1MPa to 25MPa,

The metering accuracy of the metering pump can reach up to ± 1%, and it can achieve simultaneous delivery of multiple media with individual adjustment.

The volume of the solution tank in the dosing device can range from a minimum of 0.1m3 to 20m3, and can be selected according to the dosage. There are various materials to choose from depending on the conveying medium, such as carbon steel (carbon steel lining), stainless steel, non-metallic materials (PE, PVC, PP, PTFE), etc.
