The design of pneumatic conveying system is the development process of a solution that uses air flow to transport powder, particles or flakes through pipes according to a set of operating requirements. The design of pneumatic conveying system has many complexities and requires advanced professional technology. This complexity comes from the wide variety of powder and granular materials, as well as the large changes in the operating conditions applicable to this conveying method. A proven method to develop solutions for pneumatic conveying system design. It is based on good industrial practice and our rich experience in chemical industry, food processing and pharmacy. Please read on to find out what problems we have avoided and what requirements we have considered in the process of designing and developing solutions for pneumatic conveying systems.

為什么氣力輸送系統(tǒng)設(shè)計(jì)如此重要？

Why is the design of pneumatic conveying system so important?

一個(gè)設(shè)計(jì)不當(dāng)?shù)臍饬斔拖到y(tǒng)會(huì)導(dǎo)致幾個(gè)主要的操作問(wèn)題，嚴(yán)重降低其性能和可維護(hù)性。此外，故障診斷和診斷這些問(wèn)題可能很困難，可能會(huì)花費(fèi)很多時(shí)間和精力。其中許多問(wèn)題可能會(huì)影響嵌入系統(tǒng)的處理工廠的整體性能。這是因?yàn)闅饬斔驮诩庸S中起著中心作用。它們用于將散裝材料從一個(gè)地方轉(zhuǎn)移到另一個(gè)地方進(jìn)行某種形式的加工。輸送性能的任何降低都將影響加工廠的產(chǎn)量。

A poorly designed pneumatic conveying system will lead to several major operational problems, seriously reducing its performance and maintainability. In addition, troubleshooting and diagnosing these problems can be difficult and can take a lot of time and effort. Many of these problems may affect the overall performance of the embedded system's processing plant. This is because pneumatic conveying plays a central role in the processing plant. They are used to transfer bulk materials from one place to another for some form of processing. Any reduction in conveying performance will affect the output of the processing plant.

在氣力輸送系統(tǒng)運(yùn)行時(shí)，糾正問(wèn)題往往是一個(gè)復(fù)雜的過(guò)程，而且成本很高。補(bǔ)救工作通常需要詳細(xì)的計(jì)劃和熟練的執(zhí)行，以盡量減少加工廠的停機(jī)時(shí)間。

In the operation of pneumatic conveying system, correcting problems is often a complex process with high cost. Remedial work usually requires detailed planning and skilled execution to minimize plant downtime.

有幾種類型的主要操作問(wèn)題，可能產(chǎn)生于不良的氣力輸送系統(tǒng)設(shè)計(jì)。

There are several types of major operational problems that may result from poor pneumatic conveying system design.

1、堆積和堵塞:粉末或顆粒物質(zhì)的堆積和積聚會(huì)導(dǎo)致氣力輸送系統(tǒng)內(nèi)的堵塞。這些沉積物可能導(dǎo)致能源使用增加或輸送量降低。

1. Accumulation and blockage: The accumulation and accumulation of powder or particulate matter will lead to blockage in the pneumatic conveying system. These deposits may lead to increased energy use or reduced transport.

2、限制輸送量:不合適的管道布局和管道內(nèi)組件集成不良造成的障礙物會(huì)降低氣力輸送能力。此外，如果在管道內(nèi)使用過(guò)高的空氣速度進(jìn)行輸送，則可能降低氣力輸送能力(這種效果不是直觀的)。

2. Limit delivery capacity: obstacles caused by improper pipeline layout and poor integration of components in the pipeline will reduce the pneumatic conveying capacity. In addition, if excessive air velocity is used for conveying in the pipeline, the pneumatic conveying capacity may be reduced (this effect is not intuitive).

3、彎頭磨損:對(duì)于較硬的粉狀或顆粒狀物料，輸送速度過(guò)快會(huì)增加彎頭的磨料磨損和沿管道的掃面。這可能導(dǎo)致更大的維護(hù)需求，并增加停機(jī)時(shí)間，因?yàn)檫@些部分將需要更頻繁的更換。

3. Elbow wear: For hard powdery or granular materials, too fast conveying speed will increase the abrasive wear of the elbow and the sweeping along the pipeline. This may lead to greater maintenance requirements and increased downtime, as these parts will require more frequent replacement.

4、粒子摩擦:某些粉狀或粒狀物料的輸送速度過(guò)快，會(huì)導(dǎo)致顆粒碎裂或粉碎成更小的顆粒。細(xì)顆粒是由于這些較小的顆粒以過(guò)高的速度移動(dòng)，并通過(guò)與輸送系統(tǒng)內(nèi)粗糙的內(nèi)部表面接觸而不斷破碎而產(chǎn)生的灰塵。這可能導(dǎo)致散裝物料的運(yùn)輸嚴(yán)重?fù)p壞，并可能嚴(yán)重影響輸出質(zhì)量。

4. Particle friction: some powdery or granular materials are transported too fast, which will cause the particles to be broken or crushed into smaller particles. Fine particles are the dust generated by these smaller particles moving at a high speed and constantly breaking through contact with the rough internal surface in the conveying system. This may cause serious damage to the transportation of bulk materials and may seriously affect the output quality.
