I’m a recent graduate with no mentor to guide me; apart from studying the relevant standards, what else should I do?
Thread Content
I would like to ask the experienced professionals: without any drawings available, and in order to learn instrumentation well, what else should a recent graduate do who has no mentor to guide them beyond referring to the standards? If I want to draw my own diagrams, where should I start? Thank you! This post was last edited by cocain on 2007-11-27 11:57.]
You need to tell everyone what kind of work you do, so that they can give you specific advice. The knowledge of instruments that is necessary depends on whether you are involved in instrument design, maintenance, or work as a technician in an instrument manufacturing factory; however, no matter what your role, it’s important to have a solid grasp of the basic principles of instruments. I suggest that you read some books on basic instrument knowledge on forums first.
I’m sorry; I work on automatic control design at a petrochemical design institute
Then you need to be familiar with the relevant design specifications and standards for automation control, know how to select various instruments, have a sufficient understanding of the process involved, be aware of all the norms and standards related to automation control, and also possess some basic knowledge of mechanics.
My advice: 1. Try to become familiar with the working principles and operating environments of various field instruments. 2. Compare the advantages and disadvantages of the same type of instruments from various manufacturers (you should have many selection samples available). 3. Familiar with the knowledge related to the control systems of various manufacturers (such as processors, configuration software, etc.). 4. If possible, go to the site in person to gain a more intuitive understanding. 5. Before designing, it is necessary to become thoroughly familiar with the client’s manufacturing process, as instruments are designed to serve that process. 6. Pay attention to details during design; those working on automatic control systems must be meticulous.
Try more, seize every opportunity, and learn from everyone* their strengths. Don’t be afraid of getting dirty or tired, because you won’t be doing this forever
A task will be assigned to you sooner or later; what needs to be done now is to strive to understand the guidelines.
I think you should first spend time getting familiar with the guidelines as soon as possible, so that it will be easier for you to get started when a master arrives or when you have a task to carry out. After all, the guidelines form the foundation; it’s not necessary to memorize them, but at least you should have a good understanding of them.
If you have time, take a look at the drawings created by experienced professionals. Each design firm has its own style of creating drawings; it’s best to use those created by your mentor, as following his style is the best choice
Looking at the specifications is completely useless; without any experience in engineering, those specifications are like the Nine Yin Manual. Take the time to understand the principles behind the instruments on site. When others suggest which instruments to use, one only knows one name; everything else is completely unknown. Don’t worry; everyone who does design starts from this step.
Instrument control serves the manufacturing process; you must first be familiar with the entire process flow in order to carry out effective automatic control
Thank you all, but what should we do since we don’t have the blueprints here?
You can first learn about your company’s project process, and then refer to a specific project as a guide; this will help you think more clearly when working on projects. Rules shouldn’t be read as essays; it’s more effective to look at what’s needed in each case, which also helps with better memorization.
You can look at some standard atlas to become familiar with the specifications and commonly used materials as well
Without blueprints, start by looking at the specifications (those from HG and SH), as well as the manufacturer’s samples; it’s best to consult the design manual as well. Gradually get familiar with the manufacturing processes over time
First, get familiar with the site and understand the procedures; then start working more. There’s no rush to draw diagrams – take your time. At the beginning, everyone feels confused, haha
If possible, take the design documents of the projects that are already in operation and go to the site to compare them; this will be beneficial for your future work.
Lou is in the same situation as me; we’re both currently studying the regulations to find out what isn’t allowed. It seems like those regulations aren’t very useful at all – after reading them, I forget them right away, and I don’t understand why such rules exist. My supervisor has now started to teach me the techniques involved and have me work on simple specification documents
But I really want to go and see it in person. There are some things that you can’t understand clearly just by reading the information
Those who work on design in the petrochemical industry should have very comprehensive information. You can refer to some old engineering drawings and learn on your own; it’s not that difficult. Review the knowledge you have learned on the drawings. Send over any difficulties, and I’ll explain them to you; everyone will help you.
Does anyone have samples of the instruments? Could you send them to me? 251748212@163.com
