气力输送负型和非标规格被分为两种类型的规范规划的：供给点，结构比较简单，小型，简单的方法容易清洗，并且易于保护，一个价ge优势，但该产品是比较小，一般适用于输出值2T/h以下，输送间隔为30米范围内，是一个小的值，优先系统短的时间间隔。

The negative and non-standard specifications of pneumatic conveying are divided into two types of standardized planning: supply point, with a relatively simple structure, small size, simple method easy to clean and protect, a price advantage, but this product is relatively small and generally suitable for output values below 2T/h. The conveying interval is within the range of 30 meters, which is a small value and prioritizes the short time interval of the system.

非标定制型：体系发展较为杂乱，产值规模较大时，输送时间间隔较远时，一般企业需求进行非标定制才干满意出产要求。 产值达到2t/h以上且区间在150米以下的，应考虑非标定制..

Non standard customization type: When the system development is relatively chaotic and the output value is large, and the delivery time interval is long, general enterprises need to carry out non-standard customization to meet production requirements. For products with a production value of over 2t/h and a range of less than 150 meters, non-standard customization should be considered

要知道一些气力输送的选型有，必要对气力输送有根本的了解。例如：气力输送工作原理，气体 - 固体比例，材料，颗粒尺寸的体积比重，所述材料的悬浮液速度，像气体 - 固体分型的方式。

It is necessary to have a fundamental understanding of the selection of pneumatic conveying. For example, the working principle of pneumatic conveying, gas solid ratio, material, volume specific gravity of particle size, suspension velocity of the material, and the method of gas solid separation.

负压输送设备：负压气力输送系统是指负压风机（真空泵）产生的系统负压，通过管道将负压泵入物料输送装置的输送系统，与接收机界面处的空气混合均匀。特点：负气力输送系统节省投资可以通过多点在意料之中，因为在负压设备和管道，这样可能的泄漏，因此相对干净的环境。

Negative pressure conveying equipment: The negative pressure pneumatic conveying system refers to the system negative pressure generated by the negative pressure fan (vacuum pump), which is pumped into the conveying system of the material conveying device through pipelines, and mixed evenly with the air at the receiver interface. Features: The negative pneumatic conveying system can save investment through multiple points as expected, as there may be leaks in negative pressure equipment and pipelines, resulting in a relatively clean environment.

气力输送系统又称气流输送，利用不同气流的能量，在密闭管道内沿气流发展方向不断输送颗粒状物料，是流态化技术的一种可以具体实际应用。结构简单，操作方便，传动效率高的设备，可以是水平的，输送的垂直或倾斜方向上，整个转移过程为全封闭，由小冲击气候条件;无二次污染，提高了工作条件;被输送材料不会吸收水分，污垢，或混有其它杂质，以促进材料处理和恢复。设备进行简单、结构紧凑、布置灵活，整套系统可以实现企业集中控制，自动化发展程度高。

Pneumatic conveying system, also known as airflow conveying, utilizes the energy of different airflow to continuously transport granular materials along the direction of airflow development in a closed pipeline. It is a specific practical application of fluidization technology. Equipment with simple structure, convenient operation, and high transmission efficiency can be horizontal, transported in the vertical or inclined direction, and the entire transfer process is fully enclosed under small impact climate conditions; No secondary pollution, improved working conditions; The transported material will not absorb moisture, dirt, or other impurities to promote material processing and recovery. The equipment is simple, compact in structure, and flexible in layout. The entire system can achieve centralized control for enterprises, with a high degree of automation development.
