气力输送又称为气力输灰、气力除灰，其系统有负压吸送系统、正压吹送系统。常州万佳是一家专业从事气力输送设备生产销售的厂家，设备以料封泵为主，采用的是正压吹送系统，属于微正压(低压)气力连续输送系统，具有其他任何气力输送设备组成的输送系统无法达到的可靠性。其一般采用罗茨风机，罗茨风机的高可靠性决定了系统的稳定性、可靠性。气力输送系统的主要设备料封泵本体简单，无常规气力输送工艺中阀门的频繁动作，设备故障大大降低，整个系统简介卡考，输送压力平稳，无任何冲击荷载。那么，问题来了，这么好的输灰系统，这么好的设备，可以输送的物料有哪些呢?

Pneumatic conveying, also known as pneumatic ash conveying or pneumatic ash removal, has two systems: negative pressure suction system and positive pressure blowing system. Changzhou Wanjia is a professional manufacturer engaged in the production and sales of pneumatic conveying equipment. The equipment mainly uses material sealing pumps and adopts a positive pressure blowing system, which belongs to a micro positive pressure (low pressure) pneumatic continuous conveying system. It has a reliability that cannot be achieved by any other pneumatic conveying system composed of pneumatic conveying equipment. It generally uses Roots blowers, and the high reliability of Roots blowers determines the stability and reliability of the system. The main equipment of the pneumatic conveying system, the material sealing pump, has a simple body and does not have the frequent action of valves in conventional pneumatic conveying processes, greatly reducing equipment failures. The entire system has a simple introduction, stable conveying pressure, and no impact loads. So, the question is, what materials can be conveyed with such a good ash conveying system and equipment?

气力输送系统设备料封泵适合输送粉状物料、颗粒物料、松散的不粘状态的物料、粉尘物料、水泥、粉煤灰等。可输送距离的范围，从投资和生产费用来说，常州万佳为10m到500m，输送管道为全密封输送，再管道的设计上，无论是水平倾斜还是垂直都是适用的，输送的物料都可在操控室进行云距离操作，完全达到自动化操作。特别是输送含有粉末的物料时，在密封的管道高效环保输送，无粉尘、无泄漏、更没有二次污染，对健康和安全都有着重要意义。

The material sealing pump of pneumatic conveying system equipment is suitable for conveying powdered materials, granular materials, loose and non stick materials, dust materials, cement, fly ash, etc. The range of transportable distance, in terms of investment and production costs, is 10m to 500m for Changzhou Wanjia. The conveying pipeline is fully sealed, and the pipeline design is suitable for both horizontal and vertical tilting. The conveyed materials can be operated at cloud distance in the control room, fully achieving automated operation. Especially when transporting materials containing powders, efficient and environmentally friendly transportation in sealed pipelines, with no dust, no leakage, and no secondary pollution, is of great significance for health and safety.

气力输送系统、气力输送系统是典型的流体力学、工程通用、化学工程的交叉学科，要求设计者的基础理论扎实，并有较丰富的实践经验，结构尺寸及工艺参数的确定除理论计算外，更重要的是靠经验数据的积累。根据不同的工艺线，确定结构尺寸、内部配管及合理的输送管径，才能取得好的经济效益。

Pneumatic conveying systems are typical interdisciplinary fields of fluid mechanics, engineering, and chemical engineering, requiring designers to have a solid theoretical foundation and rich practical experience. The determination of structural dimensions and process parameters relies not only on theoretical calculations, but also on the accumulation of empirical data. According to different process lines, determining the structural dimensions, internal piping, and reasonable conveying pipe diameter is necessary to achieve good economic benefits.
