(Summary description)During pneumatic conveying applications, pressure loss has many aspects. Therefore, when selecting a fan, these factors will be considered in the parameter selection. Let's talk about which factors will cause pressure loss.   1. In the process of pneumatic conveying, the pressure loss of air and materials in horizontal and vertical pipes. This part of the pressure loss includes losses in horizontal pipes and vertical pipes, mainly due to the friction between air and material and the pipe wall, the collision and friction between them, and the consumption of materials to maintain suspension; in vertical pipes, it is also required Overcome the consumption of materials to overcome gravity lifting. Second, the pressure loss when the material is accelerated. From standstill to starting and reaching a stable conveying speed, the material needs to consume the corresponding airflow energy, so this part will cause pressure loss. Third, it is the pressure loss of elbows and other similar pipe fittings. Pneumatic conveying pipes are difficult to ensure that they are all horizontal or vertical, and will vary according to the actual situation. In this case, the air and material change during transportation. At this point, due to inertial and centrifugal forces, the air and material will collide with the tube wall, and they will redistribute and start in different directions. pressure loss. Fourth, the pressure loss caused by the muffler, material gas separation, dust removal and other supporting components and equipment. Pneumatic conveying is a complete system involving filter noise reduction, post-dust removal, material-gas separation and other auxiliary equipment. It consumes the energy of the gas source and causes pressure loss. The main pressure loss of the pneumatic conveying system is the above points, which need to be fully considered when designing the pneumatic conveying system to ensure that the system has sufficient air source pressure.
