This approach is usually used for long distance pipelines and a very fine, granular, abrasive, non-abrasive, brittle and difficult to transport materials. Such as carbon black, corundum, plastic beads and quartz sand, and so on. The kinds of transportation methods can be divided into batches or continuous feed material conveyor systems, which can send a single or multiple, pipelines, pipeline and electronically controlled turbocharger, and other component parts. The system distinguish between the three modes of transmission characteristics is the largest: the pipelines from inside the transmission has been started on the storage, transportation in the pipeline at the beginning and end at the end, the pipeline is always to maintain a full load.
The working principle Bell materials through the valve, butterfly valve or expansion of the dual-butterfly, in the role of gravity was added to send in tanks, the replacement of the air through the exhaust valve to release out, making it easier to feed. Once send tank filled with materials (through the weight or level meter display can reach 80% of the volume), when the feed valve and exhaust valve immediately shut down and sealed. Then intake valve is opened, was added to the compressed air tank used to send out replacement materials. At this point along the pipeline from the booster for internal transport pressure. When sending changes tank completely empty (by the level meter display), when the air supply was immediately shut down, the material in the pipeline stop. At this point open the valve to feed material into the tank, the gas tank through a special dedicated valve was released from (the valve in the process of feeding open). As a result of pipeline transportation to the existence of material so that once again when the transmission is slow, unlike the above-mentioned three types of clock speed transmission, it is ideal for easy transportation of abrasive materials broken. As the pipeline to maintain a full load of the total made in the filling and emptying the pipeline without loss of time, less gas consumption, it is more appropriate for long-distance transmission of a single variety of materials. The system is characterized in its delivery of the entire process has a very low rate of gas flow and high pressure pipelines.
