Nanjing Xiangrui powder: pneumatic conveying, also known as airflow conveying, uses the energy of airflow to transport granular materials along the airflow direction in a closed pipe, which is a specific application of fluidization technology. The pneumatic conveying device has the advantages of simple structure, convenient operation, horizontal, vertical or inclined conveying, simple equipment configuration, small investment, low maintenance and convenient maintenance.
Nanjing Xiangrui Powder Engineering Co., Ltd. has a research and development team of pneumatic conveying technology for more than 40 years, and is equipped with a variety of physical property testing instruments and pneumatic conveying, gravity mixing, weighing and metering test devices. People often have some misunderstandings about pneumatic conveying, so how to solve them? This article will lead you to do a simple analysis.
Myth 1: horizontal pipeline is easier to transport than vertical pipeline
It is generally believed that horizontal is better than vertical, but this is not the case. When the material is transported in the horizontal pipe, it is necessary to increase the air flow rate. Because the material suspension deflection and air flow deflection are vertical in the horizontal tube, as long as a part of the force acts on the suspension, more energy will not work. In the vertical pipe, the levitation bias is the same as the airflow bias, so more energy can be used. Therefore, it is easier for materials to settle and cause blockage in horizontal pipes, but not in vertical pipes, which is more conducive to air transportation.
Error 2: increase the air volume can improve the conveying capacity
Many customers subconsciously think that as long as the air volume increases, the delivery capacity will certainly increase, but in fact this kind of cognition is wrong. Xiangrui technicians found that: when the design is at the most economic point, if all conditions are the same (pipe diameter, material, transportation interval and working condition), the transportation capacity will be much lower with the increase of wind speed and air volume. When the air volume and wind speed are reduced, the transportation capacity will increase, but when the air volume and wind speed are close to the minimum wind speed of the experiment, it is easy to cause infarction. Therefore, when transporting materials, it is necessary to choose the appropriate wind speed and air volume to maximize the economic benefits.
The design of pneumatic conveying system should be inspected and studied by technicians. In order to create a more economical and suitable pneumatic conveying system for enterprises, we should consider the selection of equipment, pipeline layout, wind speed and air volume. Nanjing Xiangrui Powder Engineering Co., Ltd. has rich experience in the design and customization of pneumatic conveying system, professional technical R & D team and strong strength. It can customize the appropriate pneumatic conveying system for various industries, which can help you avoid the mistakes and risks encountered in the customization of pneumatic conveying system.
