we discuss control system and instrumentation devices in great detail

我們將詳細討論控制系統和儀器設備

so, you can understand exactly how they work.

這樣，你就能準確瞭解它們是如何工作的。

In this video, we will learn how to read a “P&ID”

在本視頻中，我們將學習如何閱讀 "P&ID"。

which is something that engineers encounter on a daily basis.

這是工程師們每天都會遇到的問題。

P&IDs, or Piping and Instrumentation Diagrams to give them their full name,

P&ID，即管道和儀表圖的全稱、

are schematic representations of pipelines,

是管道的示意圖、

equipment, instrumentation and control systems

設備、儀器和控制系統

found in process environments such as Oil Refineries,

可在煉油廠等加工環境中使用、

Chemical Plants, Paper Mills, and Cement Plants, etc.

化工廠、造紙廠和水泥廠等。

The symbols contained in P&IDs represent the equipment in the process

P&ID 中的符號代表工藝中的設備

such as actuators, sensors, and controllers.

如執行器、傳感器和控制器。

Process equipment such as valves,

閥門等工藝設備、

instruments, and pipelines are identified by codes and symbols.

儀器和管道都用代碼和符號標識。

As well as devices and pipelines a P&ID will commonly contain,

除設備和管道外，P&ID 通常還包括

information on vents drains and sampling lines

關於通風口、排水口和取樣管線的資訊

as well as flow directions,

以及流向、

control IO and interconnection references.

控制 IO 和互連參考。

The Instrumentation codes listed in P&IDs follow a standard format,

P&ID 中列出的儀表代碼採用標準格式、

after some practice in reading P&IDs you will know these codes by heart,

經過一些閱讀 P&ID 的練習後，你就會對這些代碼瞭如指掌、

but in the meantime,

但與此同時

there are many resources on the web

網上有很多資源

where you can download these tables for reference.

您可以在此下載這些表格以供參考。

The first letter of the code identifies

代碼的第一個字母表示

the parameters that are being controlled or monitored

控制或監測的參數

for example Flow, Temperature, Level or Pressure.

例如流量、溫度、液位或壓力。

The next letter is used to define the type of control device being used,

下一個字母用於定義所使用的控制設備類型、

for example, Transmitter, Valve or Controller.

例如，變送器、閥門或控制器。

The number refers to the logical numerator,

數字指的是邏輯分子、

for example, we may have a system with 4 temperature transmitters,

例如，我們可能有一個帶有 4 個溫度變送器的系統、

it makes sense to identify these as “TT01”,

將其標識為 "TT01 "是合理的、

“TT02”, “TT03” and “TT04”.

"TT02"、"TT03 "和 "TT04"。

Let’s consider for a moment an instrument on a P&ID named “FV01”.

讓我們先考慮一下 P&ID 上名為 "FV01 "的儀器。

Looking up the code for this

查找相關代碼

we could tell this is a Flow Valve numbered 01.

我們可以看出這是一個編號為 01 的流量閥。

Symbols, circles, and lines are used to represent instruments

用符號、圓和線表示儀器

and to show how they are connected to the rest of the system.

並說明它們與系統其他部分的連接方式。

Now that we know our device FV01 is represented by a circle,

現在我們知道我們的設備 FV01 由一個圓表示、

we can also tell from the P&ID

我們還可以從 P&ID 中看出

where the instrument or device is located.

儀器或設備所在的位置。

The presence or absence of a line in the circle

圓中有無線段

determines the location of the physical device.

確定物理設備的位置。

The piping or connection lines on the P&ID also tell us about the instrument,

P&ID 上的管道或連接線也會告訴我們有關儀器的資訊、

for example, a solid line would indicate the interconnection is via pipework

例如，實線表示通過管道進行互聯

whereas a dotted line would indicate an electrical connection.

而虛線則表示電氣連接。

It is worth familiarising yourself with the different types of connection symbols

熟悉不同類型的連接符號很有必要

as this can give you an insight into the function of an instrument

因為這可以讓你瞭解樂器的功能

even before you know its code.

甚至在你知道它的代碼之前。

In this video, we have looked at the basic interpretation of a P&ID

在本視頻中，我們瞭解了 P&ID 的基本解釋

or Piping and Instrumentation Diagram.

或管道和儀表圖。

We learned that each instrument involved in the process appears on the P&ID

我們瞭解到，流程中涉及的每個儀器都會出現在 P&ID 上

and is represented by a symbol and a code.

並用符號和代碼表示。

We also learned that using this code and symbol

我們還了解到，使用這種代碼和符號

we can understand what type of device it is,

我們就能瞭解它是什麼類型的設備、

its location and how it is connected to the rest of the process.

其位置以及如何與流程的其他部分相連。

To read a P &ID effectively

有效讀取 P &ID

one must be familiar with standard instrument symbols

必須熟悉標準儀器符號

and standard identification letter codes.

和標準識別字母代碼。
