The pneumatic conveying system uses the gas as a carrier to transport material or small items in the closed pipeline. Due to the material to produce movement relative to the pipe, so the wear on pipeline is inevitable. And in some certain cases, it also can produce the phenomenon of unsmooth movement,namely it may produce the blockage. As the material performance, the pipe conditions, gas source machinery running state and operation and the weather change could produce material jam, especially in a sealed condition.It's hard to perceive the change of the above situation, thus once the jams suddenly appear,you will tend to be caught off guard, which has a great impact on the production.
1. Blockage
(1) The congestion reasons:
For a set of pneumatic conveying system with reasonable design parameters, precise manufacturing installation, and correct operation. In some certain occasional cases, it also can lead to the transporting pipe blocked. The following several aspects are used to seek the cause of blockage under this kind of circumstance.
(2)Methods to prevent blockage
In designing the pneumatic conveying device, we will choose the types and each component structure of the pneumatic conveying device and reasonably determine each process parameters of this device according to the conveying of material performance, productivity, and the actual situation of transport distance.
2.wear
In the pneumatic conveying equipment, materials (or objects) move relatively to the transporting pipe, therefore, the wear of the transporting pipe is almost inevitable. In the practical production, we often take various measures to find out the best way to reduce wear. (1) For the bending pipe, there are mainly three ways to improve its service life.
1) change the bending material, improve the wear resistance ability, adopt suitable wear resistant materials into bending and its service life can increase 10 times.
(2)The measures to reduce the wear of the straight pipe and improve its service life;
3) Try to reduce the transmission speed of airflow. For the compression type pneumatic conveying device ,we adopt the low voltage low speed transmission for best; For the carrying type pneumatic conveying device,we use the low speed high vacuum conveying for best.
