能夠正確的選擇一套合適的負壓氣力輸送設備對我們日后的加工生產、物料的輸送、效率都是關重要的，那么在選擇負壓氣力輸送設備時我們應該注意哪些方面呢?

　　Choosing a suitable set of negative pressure pneumatic conveying equipment correctly is crucial for our future processing and production, material transportation, and efficiency. So, what aspects should we pay attention to when choosing negative pressure pneumatic conveying equipment?

　　重要的就是(負壓氣力輸送)設備的選型，一般選型都是由廠家為客戶選擇，但是前提是要給負壓氣力輸送廠家提供相應正確的參數。那么那些參數會直接影響型號的選擇呢？

　　The first important thing is the selection of (negative pressure pneumatic conveying) equipment. Generally, the selection is chosen by the manufacturer for the customer, but the prerequisite is to provide the negative pressure pneumatic conveying manufacturer with the corresponding correct parameters. So what parameters will directly affect the selection of models?

　　我們要知道什么物料，粉狀的還是顆粒狀的，物料的比重是多少（比重：物料在松散狀態下自然堆積的密度，即：一立方物料的重量），一小時的輸送量，輸送距離和高度等等，這些都直接影響負壓氣力輸送設備的選型；

　　Firstly, we need to know what material it is, whether it is in powder or granular form, what is the specific gravity of the material (density: the density of the material naturally accumulated in a loose state, i.e. the weight of one cubic meter of material), the hourly conveying capacity, conveying distance and height, etc., all of which directly affect the selection of negative pressure pneumatic conveying equipment;

　　其次就是物料的特性，物料有沒有揮發、腐蝕性，是不是屬于易燃易爆的，這些會直接影響負壓氣力輸送設備的材質及密封程度；

　　Secondly, it is the characteristics of the material, whether it has volatilization and corrosiveness, and whether it is flammable and explosive, which will directly affect the material and sealing degree of negative pressure pneumatic conveying equipment;

　　還有食品行業的我們需要用到304材質或者316材質的，等等這些都需要在購買設備前提前廠家溝通好，廠家才能更好的給您提供更加準確的型號，既保證了輸送量，也可以更加的使用設備。

　　In the food industry, we also need to use 304 or 316 materials, and so on. These need to be communicated with the manufacturer in advance before purchasing equipment, so that the manufacturer can better provide you with more accurate models, ensuring both conveying capacity and safer use of equipment.
