氣力輸送設備歸于密相中壓氣力輸送，適用于不易破碎顆粒、粉料物料的運送。氣力輸送廣泛應用于鑄造、化工、醫藥、糧食的職業(yè)。

Pneumatic conveying equipment belongs to dense phase medium pressure pneumatic conveying and is suitable for the transportation of non easily broken particles and powder materials. Pneumatic conveying is widely used in professions such as casting, chemical engineering, medicine, and grain production.

氣力輸送是使用氣流的能量，在密閉管道內沿氣流方向運送顆粒狀物料，是流態(tài)化技能的一種具體應用。氣力輸送設備的結構簡(jiǎn)略，操作便利，可作水平的、筆直的或歪斜方向的運送，在運送進(jìn)程中還可一起進(jìn)行物料的加熱、冷卻、枯燥和氣流分級等物理操作或某些化學(xué)操作。

Pneumatic conveying is a specific application of fluidization technology that uses the energy of airflow to transport granular materials along the direction of airflow in a closed pipeline. The structure of pneumatic conveying equipment is simple, easy to operate, and can be used for horizontal, straight, or skewed transportation. During the transportation process, it can also perform physical operations such as heating, cooling, drying, and air flow classification, as well as certain chemical operations together.

氣力輸送系統

氣力輸送的首要特點(diǎn)是運送量大，運送間隔長(cháng)，運送速度較高;能在一處裝料，然后在多處卸料。依據顆粒在運送管道中的密布程度，氣力輸送分為：

The primary characteristics of pneumatic conveying are large transport volume, long transport interval, and high transport speed; It can be loaded in one place and unloaded in multiple places. According to the density of particles in the transport pipeline, pneumatic conveying is divided into:

1、稀相運送：固體含量低于1-10kg/m3，操作氣速較高(約18～30m/s)，運送間隔基本上在300m 以?xún)取，F老練設備料封泵來(lái)說(shuō)，運送操作簡(jiǎn)略無(wú)機械滾動(dòng)部件，運送壓力低，無(wú)修理、免保護!

1. Dilute phase transportation: Solid content below 1-10kg/m3, high operating gas velocity (about 18-30m/s), transportation interval is basically within 300m. For experienced equipment such as sealed pumps, the transportation operation is simple without mechanical rolling parts, the transportation pressure is low, there is no repair, and no protection is required!

2、密相運送：固體含量10-30kg/m3或固氣比大于25的運送進(jìn)程。操作氣速較低，用較高的氣壓壓送。 現老練設備倉泵，運送間隔達到500m 以上，適合較遠間隔運送，但此設備閥門(mén)較多，氣動(dòng)、電動(dòng)設備多。運送壓力高，一切管道需用耐磨材料。

2. Dense phase transportation: transportation process with solid content of 10-30kg/m3 or solid gas ratio greater than 25. Operate at a lower air speed and use a higher air pressure for delivery. The experienced equipment warehouse pump has a transportation interval of over 500m and is suitable for long-distance transportation. However, this equipment has many valves and pneumatic and electric equipment. The transportation pressure is high, and all pipelines require wear-resistant materials.
