pneumatic conveying pump

Pneumatic conveying pump

Pneumatic conveying pump is an emerging science and technology that uses pressurized pipe flow to convey powdery and granular objects. Because it has high productivity, simple structure, can be raised and lowered, and is easy to operate, it can be transported over long distances regardless of weather and location. During the transportation process, process operations such as converging, diverting, mixing, crushing, grading, drying, cooling and dust removal, and chemical reactions can be performed. The closed process not only ensures that the items are not damp, stained, or mixed with foreign matter, but also meets the requirements of environmental protection.

Vacuum pump for pneumatic conveying

• A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physical chemical methods to evacuate the pumped container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a closed space.
• According to the working principle of vacuum pumps, vacuum pumps can basically be divided into two types, namely gas collection pumps and gas transfer pumps. It is widely used in metallurgy, chemical industry, food, electronic coating and other industries.

What is pneumatic conveying ？

• Pneumatic conveying is a technology that uses airflow to transport materials through pipes‌. It uses compressed air to push bulk materials to move in the direction of air flow in the pipeline to realize material transportation. The pneumatic conveying device has a simple structure and is easy to operate. It can convey materials horizontally, vertically or inclined, and can simultaneously perform operations such as heating, cooling, drying and air flow classification during the conveying process.
• The working principle of pneumatic conveying is to use the kinetic energy of the air flow to make the bulk materials move along the pipeline with the air flow in a suspended state. According to the direction and pressure of the air flow, pneumatic conveying can be divided into suction type, pressure feeding type and mixed type. The suction type uses an exhaust fan to create a vacuum, so that the material is sucked into the pipeline; the pressure type uses a blower to press air into the pipeline, and the material is transported along with the air flow; the hybrid type is a combination of the above two methods.
• Pneumatic conveying has a wide range of applications, including foundry, chemical industry, metallurgy, building materials, grain processing and storage, shipbuilding, machine manufacturing and transportation. Due to its high efficiency, small footprint, economical and environmentally friendly characteristics, pneumatic conveying has become an indispensable technology in many industrial fields.
• The advantages of pneumatic conveying include high efficiency, small footprint, economical and environmentally friendly. It can continuously convey loose materials, and the process is closed and is not affected by climate and environment. In addition, pneumatic conveying can also perform multiple process operations at the same time, such as crushing, drying, grading, etc., to improve production efficiency and reduce worker labor intensity.

How does pneumatic conveying system work ?

• The working principle of the pneumatic conveying system is to use the flow kinetic energy generated by the high-speed flowing air in the conveying pipeline to suspend the particles, and then transport the granules from one place to another under the promotion of the kinetic energy of the air flow.
• The pneumatic conveying system mainly consists of the following parts:
• ‌Feeder‌: Responsible for adding materials to the conveying pipeline.
• ‌Conveyor pipe‌: Connects various components to realize material transportation.
• ‌Separator‌: Separates materials from the air flow.
• ‌Air Dust Collector‌: Removes dust in the airflow to ensure clean airflow.
• ‌Fan or vacuum pump‌: Provides power to make air flow in the pipe‌.
• Pneumatic conveying systems can be divided into several types according to the conveying method:
• ‌Pressure feeding type‌ (positive pressure transportation): The gas pressure is higher than atmospheric pressure, suitable for long-distance transportation.
• ‌Suction type‌ (negative pressure transportation): The gas pressure is lower than atmospheric pressure, suitable for short-distance transportation.
• ‌Hybrid type‌: Combining the advantages of positive pressure and negative pressure transportation, it is suitable for complex working conditions.
• ‌Flow conveying‌: A variant of material suspension conveying, suitable for specific materials‌.

Types of pneumatic pumps

• ‌Pneumatic pumps are mainly divided into the following categories: pneumatic gas pumps, pneumatic diaphragm pumps and pneumatic micro pumps. ‌
• Pneumatic gas pump‌:
• Pneumatic gas pumps are mainly used for high-pressure gas boosting and can produce high-pressure gas up to 90Mpa. It can pressurize most gases such as hydrogen, air, nitrogen, and natural gas.
• The characteristics of this pump include the ability to pressurize most gases, including corrosive gases (the internal core is made of stainless steel), a large pressure test range, low operating sound, no need for any power supply, and is suitable for flammable and explosive gases.
• Pneumatic diaphragm pump‌:
• The pneumatic diaphragm pump is a new type of conveying machinery that uses compressed air as the power source and is suitable for various corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids.
• This kind of pump is made of a variety of materials, such as aluminum alloy, stainless steel, polypropylene, PVDF, etc., and uses different rubber or plastic materials according to different liquid media to meet the needs of different users.
• Pneumatic micro pump‌:
• Pneumatic micropumps are small in size, light in weight, and easy to carry. They are suitable for occasions that require smaller gas flow or space restrictions.
