Urgent! I would like to ask fellow sailors about technical discussions regarding air delivery systems!

Since you are an expert in equipment, you deal with things related to equipment such as its operating principles and whether its structure is reasonable; you choose the material suitable for the equipment based on the properties of the materials being handled, and you conduct a simple verification of the equipment selected by the manufacturer according to its conveying capacity, and so on. Anyway, it’s you who is making the purchase, so ask the manufacturer to provide more details; if you don’t understand something, have them explain it to you. Or there may be other people in charge – just listen to them. If you don’t understand something, take notes, and then read more books or browse forums.

PS: Don’t make the font size of the post so large; it looks unbalanced

Thank you, I need to learn more in the future!* Those who study equipment have a lot to learn!

For example, whether the fan flow meets the requirements, the outlet pressure, and whether the current is normal. Is the control range wide enough? How is the machine’s dynamic balance? What about vibration and temperature? Pressure drop of the air supply system, etc

Hehe, it’s about to be upgraded; posting my own thread shouldn’t violate the rules, right? “Since the technology used by qualified air-conveying manufacturers is quite mature, there are many non-standard and empirically-based designs in the system.” Therefore, the clarification of the ventilation system technology can be done at varying levels of depth; you can rely entirely on the other party’s system for calculations. During the clarification process, discussions are held with the other party regarding the design scheme, the scope of supply, and the specific requirements related to mechanical, electrical, and instrumentation aspects of this project. Of course, if your company is competent enough, you can also carry out the calculations on your own during the preliminary design stage; during the clarification phase, you can have more in-depth discussions with the manufacturer regarding the system calculations. Given the current situation of the poster, it is recommended to take two steps. Treat this project as a practice opportunity, focusing on defining the boundary points and the scope of supply work, while making every effort to gain a comprehensive understanding of the entire system. The second step is, during the project implementation process, to learn as much as possible from your mentor, to read various manuals and documents, and to gain more practical experience on site, in order to lay a foundation for future professional knowledge. For beginners, it is recommended that you pay attention to the following points: 1. Matching of system capabilities: Consider the upstream granulation capacity and design with sufficient margin ； Downstream packaging capacity: pay attention to the impact of production scheduling and warehouse splitting on the conveyor belt ； 2. Optimization of the system design: First, you need to provide the manufacturer with a suggested layout diagram for the delivery pipelines as well as an equipment layout diagram, and discuss optimizations with them. At the same time, the plan for the conveying and mixing lines also needs to be determined. After the manufacturer conducts systematic calculations based on this and other parameters, the configuration of the fans and the backup unit options, along with other details, can be discussed further ； 3. Scope of supply: It is relatively easy to provide the system as a complete set via air delivery; since the pipes are manufactured by the manufacturer, the connection points are only at the outlets of the main material pipes and those connecting to the utility systems. However, the supply work for specialized areas such as pipeline electrical and instrumentation systems still needs to be carried out with as much care as possible ； 4. Design basis and project specifications: The design basis must be clearly transferred. Furthermore, the general requirements specified in various professional engineering regulations must be implemented ； 5. Equipment specifications: These refer to the specific details of the moving and stationary equipment as well as the pipelines, which is what you asked about. This is where engineering experience comes into play; it cannot be resolved in a short time, and it is hoped to be achieved in the second step mentioned above. During the initial communication, listen and ask more questions from the manufacturer and the technicians; later on, observe and think more. Here, only a few examples are given. For example, oil-free fans are used, along with safety valves at the fan outlet, settings for high pressure and temperature alarms, as well as settings for check valves and switching butterfly valves ； Selection of different types of rotary valves for powdery materials ； Determination of hydrocarbon oxygen content in closed-systems: how to prevent the silo from collapsing due to negative pressure ； SHOT PEENED treatment of material transfer pipelines, etc. 6. Control methods of the system 7. Thoroughly vet subcontractors: In the ducting industry, there are only a few options available for key equipment and pipes, making it relatively easy to control things. The rest are the general requirements in the technical attachments, such as inspections, quality assurance, spare parts, etc.; use the wording from your own company’s documents. Wish success in learning * for the first time”
