Introduction to Negative pressure pneumatic conveying, advantages, characteristics and principles of Powder conveying

Negative pressure pneumatic conveyingis a reliable material conveying equipment for conveying powdery materials under high pressure.，it is an ideal choice for customers to buy Negative pressure pneumatic conveying。

1、Brief introduction of Negative pressure pneumatic conveying

Negative pressure pneumatic conveyingit uses the kinetic energy and pressure energy of air flow to transport materials from the starting point to the destination pipeline.，Simple structure and advanced technology.，it is usually composed of control system, Conveying pipeline system, control system, Air source system and Conveying pipeline system。

2、Structural characteristics of Negative pressure pneumatic conveying

The Negative pressure pneumatic conveying structure is introduced as follows:

1. Air source device

The air source device is the power core of the Negative pressure pneumatic conveying system, which provides the airflow power needed for transportation. Common air source equipment includes roots blower, compressor, centrifugal blower and water ring vacuum pump. These devices can generate stable airflow and provide sufficient power for the transportation of materials.

2. Conveying pipeline system

The conveying pipeline is a channel for conveying materials after mixing with airflow. It is made of wear-resistant and corrosion-resistant materials to ensure that the materials will not be polluted or damaged during transportation. The diameter, shape and length of the pipeline will be designed according to the characteristics and delivery capacity of the transported materials. In addition, the pipeline system may also include some auxiliary fittings, such as valves, elbows, expansion joints, etc., for regulating air flow and pipeline connection.

3. Feeding device

The feeding device is responsible for feeding materials evenly and stably into the conveying pipeline. It is usually installed at the beginning of the system, and uses the negative pressure or positive pressure formed by the air source device to mix materials with air in a certain proportion and send them into the pipeline. Common feeding devices include rotary valves, screw conveyors, rotary feeders, screw pumps, silo pumps and Venturi nozzles. The selection of feeding device should be considered comprehensively according to the characteristics of materials and transportation requirements.

4. Bunker system

The silo temporarily stores and releases materials. The silo is usually designed as a pyramid or conical structure to facilitate the storage and unloading of materials. The design of silo needs to consider the different problems of materials in the process of storage and unloading and the flow form of materials.

5. control system

The control system is the "brain" of the Negative pressure pneumatic conveying system, which is responsible for monitoring and controlling the whole system. Through the control equipment such as programmable controller, the parameters such as airflow speed, feed rate and system pressure can be accurately adjusted and controlled to ensure the stable operation of the system and meet the production requirements.

3、Negative pressure pneumatic conveying function

Negative pressure pneumatic conveyingit has the functions of Closed conveying, Explosion-proof involves, Physical processing assistance, material handling and Automatic control，Air flow is generated by compressed air or other gases, and a certain air flow speed and pressure are formed in the pipeline. These air currents suspend the material particles in it, or transport the materials along the pipeline in a group state. In this process, the material particles are in a liquid state under the action of airflow, so as to realize the continuous and stable transportation of materials.，is a common Negative pressure pneumatic conveying。

4、Negative pressure pneumatic conveying characteristics

Negative pressure pneumatic conveyingthe main features are easy installation, Wide range of conveying materials, Low energy consumption, Quantitative transportation and The conveying speed is faster，in the course of work,Using the dynamic pressure and static pressure of air, the material particles are suspended in the airflow or transported in groups along the pipeline. The former is called material suspension transportation, and the latter is called material group transportation.，It has a wide range of uses, and is often used inHeating, cooling and drying,Dust removal and essence,Long-distance and multipoint transportation,cut down on energy consumption,Environmental protection and cleaner production and so on。

5、Advantages of Negative pressure pneumatic conveying principle

Negative pressure pneumatic conveyingthe principle is simple.Using the dynamic pressure and static pressure of air, the material particles are suspended in the airflow or transported in groups along the pipeline. The former is called material suspension transportation, and the latter is called material group transportation.，the product looks beautiful.，the advantage is In the process of conveying, various technological operations can be carried out at the same time, such as smash.、The conveying system is closed, which can prevent the materials from being affected with damp, soiled and mixed with other sundries in the conveying process, and ensure the conveying quality of the materials.、Materials are transported by closed pipelines.，Less dust flying, meeting the requirements of environmental protection, fully sealed and pollution-free transportation.、The materials collected from several points can be sent to one place or one place to scattered points, and remote operation can be realized.、The pipeline layout is flexible, and it can be arranged according to the specific terrain.，meet the needs of material transportation。

6、How much is the Negative pressure pneumatic conveying?

The Negative pressure pneumatic conveying price is introduced as follows:

1. product function

The more functions a product has, the higher its manufacturing cost, so that the product can be used by customers as much as possible, which can create more useful value for customers, so the price will be higher.

2. technology content

High-tech products need more advanced technology to support them, so products with higher performance will also lead to a general increase in their prices, and vice versa.

3. service

Service factors always affect the sales price of products, and high-quality service will make customers have greater satisfaction and recognition. The service factors mainly include pre-sales service, in-sales service and after-sales service. For each stage of service, our company takes the price factor into account and makes a reasonable judgment between service and price, so that the Negative pressure pneumatic conveying price and service can meet the actual needs of customers.

4. raw material

The quality of material selection is one of the main factors that directly affect the Negative pressure pneumatic conveying. If the quality of material selection is better, the price may be more expensive. Therefore, customers must first understand the quality of material selection before purchasing products, and then compare whether the quality and price match.

5. Quality advantages and disadvantages

As we all know, the service life of products with excellent quality will be longer, and at the same time, the benefits created by such products for customers will be higher, which will lead to an increase in the cost of products and a high sales price of products.

Negative pressure pneumatic conveying

Negative pressure pneumatic conveyingit has the functions of Automatic control, Explosion-proof involves, Closed conveying, Physical processing assistance and material handling，it is widely used in chemical industry, power, metallurgy, cast, build a ship and other industries，Not only can the materials from multiple feeding points be transported to the unloading point in turn, but also the materials from multiple feeding points can be transported to the unloading point at the same time, and remote operation can be realized.、PLC intelligent control, high degree of automation and simple operation.，meet the needs of material transportation、Can realize the transportation of materials in a closed pipeline.，No dust leakage, environmental protection and pollution-free, fully sealed and pollution-free transportation.、In the process of conveying, various technological operations can be carried out at the same time, such as grade.、It is suitable for centralized transportation from many places to one place, with one or several feeding points, and realizes long-distance operation.。
