Selection of Roots blower in pneumatic conveying
whenRoots blower equipmentWhen used for pneumatic conveying, there are many aspects of pressure loss, so when selecting Roots blowers, these factors will be considered in parameter selection. Shandong Juheng Environmental Protection Equipment Co., Ltd. introduces to you the aspects of these pressure losses
Firstly, in the process of pneumatic conveying, the materials in horizontal and vertical pipelines will affect the pressure loss in the pipelines
Both vertical and horizontal pipelines can cause pressure loss, which comes from the friction between air and materials in the pipelines, collisions and friction between them, as well as the consumption of materials to maintain suspension; In vertical pipeline transportation, it is necessary to overcome the consumption of material suspension and lifting.
Secondly, pressure loss during material acceleration
The material is pushed from a static state to a stable speed by pneumatic force, which requires the consumption of corresponding airflow energy, which can also cause pressure loss.
Thirdly, pressure loss of elbows and similar fittings
Because pipelines are arranged according to actual conditions, it is difficult for them to be in a horizontal or vertical state. In this case, the air and material will be redirected during the conveying process. At this point, due to the effects of inertia and centrifugal force, air and material will collide with the pipe wall, change direction, redistribute and start, causing
Significant pressure loss
Fourthly, equipment such as material separators, silencers, and dust collectors can cause pressure loss.
Pressure loss caused by muffler, material gas separation, dust removal and other supporting components and equipment
Pneumatic conveying is a complete system that involves other supporting equipment such as filtering and noise reduction, post dust removal, and material gas separation. This will consume the energy of the gas source and cause pressure loss. The main pressure loss surfaces of pneumatic conveying systems are the above pointsPneumatic conveying systemIn the design, it is necessary to fully consider to ensure that the system has sufficient workload
