2、Working principle of Positive pressure conveying equipment

Positive pressure conveying equipmentat work,Mainly based on aerodynamic force, compressed air or other gases generate airflow, so that material particles are suspended in the airflow or transported in groups along the pipeline. In pressure transportation, high-pressure gas pushes materials to flow along the pipeline; In vacuum transportation, the material is sucked and transported to the target position through the negative pressure environment in the pipeline.。

3、Introduction of advantages of Positive pressure conveying equipment

The advantages of Positive pressure conveying equipment are as follows:

1. Improve conveying efficiency

The continuity and high efficiency of the Positive pressure conveying equipment enable the materials to reach the destination quickly and accurately, reduce the waiting time and material accumulation, and thus improve the overall production efficiency.

2. energy saving and environmental protection

The whole process of the Positive pressure conveying equipment system is carried out in a closed state, so the secondary pollution of materials during transportation can be avoided.

3. Low maintenance cost

The Positive pressure conveying equipment device has simple structure and few moving parts, so the maintenance cost is relatively low. At the same time, because the transportation process is carried out in the closed pipeline, the occurrence of equipment wear and failure is reduced.

4. be of simple construction

The structure is relatively simple and the operation is very convenient. It can be transported flexibly in horizontal, vertical or inclined directions to adapt to different production environments.

5. Strong adaptability

The Positive pressure conveying equipment system can transport a variety of materials, including powdery, granular, fibrous and small block materials, and has strong adaptability. At the same time, for materials with unstable chemical properties, inert gas can also be used for transportation to ensure the stability of materials during transportation.

4、Positive pressure conveying equipment use

The purpose of Positive pressure conveying equipment is introduced as follows:

1. Mixing and classification

In the process of conveying, the Positive pressure conveying equipment system can cooperate with other equipment to realize the mixing and grading operation of materials, and improve the production efficiency and product quality.

2. Bulk material transportation

The Positive pressure conveying equipment is especially suitable for conveying powdery, granular and flowable bulk materials. These materials include, but are not limited to, cement, fly ash, grain, plastic particles, pharmaceutical powder, etc. Through the Positive pressure conveying equipment, these materials can be efficiently transferred between different production links or equipment.

3. material handling

Positive pressure conveying equipment system is widely used in conveying all kinds of powdery, granular and small block materials. These materials include, but are not limited to, cement, fly ash, grain, plastic particles, ore, pulverized coal, pharmaceutical powder, etc. Through the pipeline system, these materials can be efficiently and continuously transported from one place to another, greatly reducing the complexity and cost of manual handling and mechanical transportation.

4. Heating, cooling and drying

Heating, cooling or drying equipment can be installed in the Positive pressure conveying equipment pipeline to carry out necessary treatment of materials to meet the specific requirements in the production process.

5. Long distance transportation

The Positive pressure conveying equipment system can realize long-distance material transportation and meet the demand of long-distance material transfer. This is especially important for some large factories or cross-regional material transportation.

5、Structural characteristics of Positive pressure conveying equipment

The Positive pressure conveying equipment structure is introduced as follows:

1. Air source device

The air source device is the power core of the Positive pressure conveying equipment 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. dust pelletizing system

Dust removal system is very important for the environmental protection performance of Positive pressure conveying equipment system. It is responsible for handling the dust and waste gas generated in the transportation process to ensure that the discharge meets the requirements of environmental protection. Dust removal system usually includes dust collector, fan and discharge pipeline. According to different material characteristics and environmental protection requirements, different dust removal equipment and technical schemes can be selected.

4. Air source device

The air source device is the power core of the Positive pressure conveying equipment 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.

5. 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.

6、Positive pressure conveying equipment price concessions

The Positive pressure conveying equipment price is introduced as follows:

1. geographical position

hydejinan, Shandong province, the transportation is convenient, and the corresponding cost of transporting Positive pressure conveying equipment is low, which reduces the cost of selling Positive pressure conveying equipment by manufacturers, and the price will also decrease.

2. product costs

Product manufacturers are different, and the cost spent by each manufacturer in producing products is definitely different. The higher the cost of producing products, the higher the price of products set by manufacturers. On the contrary, the Positive pressure conveying equipment price is low.

3. market supply and demand

If there is a large demand for Positive pressure conveying equipment in the market, the price of products will naturally be high. On the other hand, if the supply of this equipment exceeds demand, then manufacturers will have inventory accumulation. In order to dispose of these products as soon as possible, some manufacturers will sell them by lowering the price of products, so the price will be very low.

4. product configuration

The higher the hardware configuration, the greater the product cost, so the sales price of such products will be higher. hyde powder pays special attention to the hardware configuration of products, so hyde Positive pressure conveying equipment has a higher cost performance.

5. Product technology

The more advanced the technology, the higher the price will be, otherwise the equipment price will be low, and users must pay attention to whether their own technology meets the production requirements when purchasing equipment.
