An intelligent, safe and precise solution for chemical injection in various industries.
He represents
In many industries, such as oil and gas, petrochemicals, water and wastewater treatment, power plants, and the chemical industry, precise chemical dosing is crucial for increasing process efficiency, reducing corrosion, preventing deposits, and improving end-product quality. A key piece of equipment for achieving this goal is a mobile chemical dosing system with a control cabinet and solenoid valve .
These devices are characterized by their small size, portability, high precision, and safety, and are therefore among the most widely used solutions for chemical injection in various sizes. This article examines in detail the design, features, advantages, applications, selection, and operating principles of portable, box-type chemical injection devices with solenoid valves.
What is a chemotherapy injection set?
A chemical injection system is an integrated mechanical, electrical and control system designed and manufactured to precisely inject a specific quantity of chemicals into pipes, tanks or industrial processes.
These packages typically contain the following components:
-
High-pressure fuel pump
-
Chemical storage tanks
-
Control devices and precision measuring instruments
-
Valves and fittings
-
Security system
A portable chemical injection device with a solenoid valve is presented.
ID
The portable chemical injection device with solenoid valve is an injection device with the following features:
-
It is located inside a protected metal or polymer chamber.
-
It is lightweight and portable, making transport easy.
-
Precise flow control is achieved through the use of a jet pump equipped with a solenoid valve.
This type of packaging is particularly suitable for projects with limited space, segmented injection molding, and for laboratory and semi-industrial applications.
What is an electromagnetic high-pressure fuel pump? And how does it work?
Electromagnetic injection pumps are among the most common metering pumps. They work by alternately moving a diaphragm using electromagnetic forces (from a solenoid valve).
Operating principle
-
A magnetic field can be generated in a coil by applying an electric current to it.
-
The nerve nucleus is shifted forward, and the diaphragm moves accordingly.
-
The chemicals enter the pump via a check valve on the suction side.
-
After the power supply is disconnected, the membrane returns to its original position.
-
A chemical substance is injected into the injection line under pressure.
Properties of electromagnetic pumps
-
High injection accuracy
-
Low power consumption
-
Suitable for low to medium flow rates.
-
Manual or automatic control option

4. Control and measuring devices as well as electrical equipment
Control cabinets for solenoid valves typically include the following components:
-
Internal distribution board
-
On/Off switch
-
Valves and safety devices
-
It can be connected to a programmable logic controller (PLC) or a 4-20mA signal.
5. Valves and fittings
To ensure normal and safe operation:
-
Safety valve
-
Fuel injector
-
non-return valve
-
Chemical-resistant pipes and fittings
Advantages of a portable chemical injection device with a solenoid valve.
Compact and small design
Suitable for events and projects where space is limited and the installation of large-format equipment is not possible.
Easy to transport and move.
Ideal for temporary projects, pilot projects, laboratories and mobile units.
High injection accuracy
Electromagnetic pumps enable precise control of the injection volume.
Highly coated
By housing the equipment in a protective container , the risk of leaks and the risk of operator exposure to chemicals can be reduced.
Quick setup and installation
The component is already pre-assembled; only a power source and an infusion tube need to be connected.
Reasonable price
It is more economical than electrical or hydraulic systems.
