Equipment selection

For issues related to gear pumps, screw pumps, rotor pumps, and Roots pumps, feel free to contact me at any time.

Internal documents are all encrypted. To be honest, each department has its own set of procedures and requirements; I can only give you a general overview. First, look at the process flow diagram to get a sense of the overall process, then determine the various process parameters as well as the tasks assigned to different departments. Communicate more with them to clarify their requirements. By the way, are you dealing with equipment or automation systems? Let me talk about automation systems. Next, refer to the selection table and take into account factors such as the environment, the medium used, cost, and available installation space in order to decide on the type and grade of equipment, as well as how it should be installed. It’s important to know where the boundary between automation systems and piping equipment lies; clearly specify the tasks assigned to piping or equipment. Then create an index table that lists all instruments by type, including their specifications, installation locations, and any additional notes. Once the piping diagrams are available, you can proceed to create the construction drawings for the instruments, determining how they should be wired, where the cable trays should be placed, and how gas detection systems should be integrated. After that, it’s necessary to calculate the quantities of materials needed, the length of cables, their specifications, and other related details. Also, consider whether it’s necessary to have access to the control room; if so, think about how the cable trays will fit inside the control cabinets, the safety measures required within those cabinets, and the need for redundancy. Create a wiring diagram, making sure to include the instrument identifiers and other relevant details. As for the layout of the control console, I’m not very familiar with that either – I’ve never dealt with it before. The above is the general process; when the final output is produced, there are still many files. Many of the steps mentioned are quite complicated and require careful attention. Experience is very important – in other words, if you haven’t worked with this before, you won’t be aware of many details, which makes it easy to make mistakes. I’d advise you that self-study has no future – you won’t have access to enough resources, and without being involved in the entire process, it’s already difficult to get started, let alone handle all the details. There’s no way to achieve optimization or innovation either; the usual daily tasks consist of mechanical repetition and dealing with various problems. The key is to think carefully about how to break through this situation.

The selection of equipment is mainly based on experience gained from practice, followed by theoretical analysis. When it’s time to choose equipment for a project and one isn’t sure about the best choice, it’s necessary to take into account the production process and determine the working conditions that the equipment must meet. Then, the technical staff from the equipment manufacturers can develop selection proposals for evaluation. It’s useful to consult with several different equipment manufacturers; over time, insights will be gained through continuous practice and reflection
