如何選擇氣力輸送對于企業(yè)來(lái)說(shuō)非常重要，今天我將氣力輸送縮小的一個(gè)非常小的階段來(lái)讓大家更熟悉氣力輸送系統的選擇。

　　How to choose pneumatic conveying is very important for enterprises. Today, I will narrow down pneumatic conveying into a very small stage to make everyone more familiar with the selection of pneumatic conveying systems.

　　1.考慮氣力輸送材料因素

　　1. Consider the factors of pneumatic conveying materials

　　粒徑和形狀對輸送階段具有巨大影響，因為它決定了流動(dòng)性以及移動(dòng)材料需要多少空氣。 這指的是每個(gè)粒子的形狀。

　　The particle size and shape have a significant impact on the conveying stage, as they determine the fluidity and how much air is required to move the material. This refers to the shape of each particle.

　　散裝密度是其散裝形式的材料，有助于確定氣動(dòng)系統的設計以及將散裝從一個(gè)地方移動(dòng)到另一個(gè)地方所需的內容。

　　Bulk density is the material in its bulk form, which helps determine the design of pneumatic systems and the content required to move bulk from one place to another.

　　水分含量會(huì )影響流動(dòng)性，是設計氣動(dòng)系統時(shí)的重要考慮因素。水分會(huì )導致材料粘結管道堵塞。

　　Moisture content can affect fluidity and is an important consideration when designing pneumatic systems. Moisture can cause blockages in material bonding pipelines.

　　易碎性是指材料粉碎的容易程度。 許多材料在與管道表面接觸或者彎頭碰撞時(shí)破裂。如果您擔心這一點(diǎn)，應使用較低的速度來(lái)減少顆粒破碎變形粘結性意味著(zhù)材料在壓力下會(huì )相互粘附，從而在輸送管道內產(chǎn)生問(wèn)題。

　　Fragility refers to the ease with which a material can be crushed. Many materials break when they come into contact with the surface of pipelines or collide with bends. If you are concerned about this, you should use lower speeds to reduce particle breakage, deformation, and adhesion, which means that materials will adhere to each other under pressure, causing problems in the conveying pipeline.

　　吸濕性是材料容易吸收空氣中水分的能力。 這些材料可以涂覆在輸送線(xiàn)的壁上并導致堵塞。 使用干燥空氣可有助于減少管線(xiàn)中的水分。

　　Moisture absorption is the ability of a material to easily absorb moisture from the air. These materials can be coated on the walls of the conveyor line and cause blockages. Using dry air can help reduce moisture in pipelines.

　　2.三種常見(jiàn)的氣力輸送要考慮輸送的三個(gè)基本類(lèi)別。 了解這個(gè)階段將有助于確定如何選擇氣力輸送系統

　　2. Three common types of pneumatic conveying should consider the three basic categories of conveying. Understanding this stage will help determine how to choose a pneumatic conveying system

　　密相氣力輸送：密相氣力輸送采用的系統為低速輸送系統。 材料不會(huì )懸浮在空氣流中，這樣一來(lái)材料和氣力輸送系統本身的磨損并不多。 如果是易碎材料需要選擇這種類(lèi)型的系統，因為它的低速度可以減少對顆粒的損害。 甚至略微吸濕的材料也不需要使用空氣干燥設備。

　　Dense phase pneumatic conveying: The system used for dense phase pneumatic conveying is a low-speed conveying system. The material will not be suspended in the airflow, so there is not much wear on the material and the pneumatic conveying system itself. If it is a fragile material, this type of system needs to be selected because its low speed can reduce damage to particles. Even slightly hygroscopic materials do not require the use of air drying equipment.

　　半密相氣力輸送：當只有一部分材料懸浮在空氣流中進(jìn)行輸送的情況時(shí)，我們一般稱(chēng)為半密相氣力輸送系統。 半密相氣力輸送系統適用于處于可通風(fēng)狀態(tài)的產(chǎn)品，如水泥或粉煤灰。 半密相氣力輸送系不適于較大的顆粒，較長(cháng)的輸送距離或具有高濕度的材料使用，因為它們容易在管道內堵塞。

　　Semi dense phase pneumatic conveying: When only a portion of the material is suspended in the air flow for conveying, we generally refer to it as a semi dense phase pneumatic conveying system. The semi dense phase pneumatic conveying system is suitable for products that are in a ventilated state, such as cement or fly ash. Semidense phase pneumatic conveying systems are not suitable for larger particles, longer conveying distances, or materials with high humidity, as they are prone to clogging in pipelines.

　　稀相氣力輸送：稀相氣力輸送是一種高速系統，特點(diǎn)是材料不斷懸浮在氣流中。 材料基本不會(huì )在任何位置積聚在輸送管道的底部。 最好用于密度較小的非磨蝕性，非易碎材料，例如面粉或玉米淀粉。 較大的材料需要更高的氣流以保持顆粒懸浮，并且因為稀相氣力輸送速度過(guò)快與管道壁和彎頭的摩擦，材料基本不可能保持較高完整度。但是如果您不關(guān)心物料的完整度可以忽略。

　　Dilute phase pneumatic conveying: Dilute phase pneumatic conveying is a high-speed system characterized by the continuous suspension of materials in the airflow. The material will not accumulate at the bottom of the conveying pipeline in any position. It is best used for non abrasive, non fragile materials with low density, such as flour or corn starch. Larger materials require higher airflow to maintain particle suspension, and due to the fast speed of dilute phase pneumatic conveying and friction with pipeline walls and bends, it is almost impossible for the material to maintain high integrity. But if you don't care about the integrity of the materials, you can ignore it.

　　最后需要注意的是：

　　Finally, it should be noted that:

　　在決定氣動(dòng)輸送系統時(shí)，還要記住其他幾個(gè)問(wèn)題。 將輸送線(xiàn)和系統設備接地可以減少靜電。 此外，有毒材料應與真空系統一起使用，以防止泄漏泄到環(huán)境中。 最后，一些材料在暴露于空氣時(shí)可形成爆炸性混合物，需要在輸送系統中使用替代氣體。

　　When deciding on a pneumatic conveying system, there are several other issues to keep in mind. Grounding the conveyor line and system equipment can reduce static electricity. In addition, toxic materials should be used in conjunction with vacuum systems to prevent leakage into the environment. Finally, some materials can form explosive mixtures when exposed to air, requiring the use of alternative gases in the delivery system.
