What process flow diagram is it? In the industrial products from raw materials to final process of the finished product, we need to use a kind of professional illustration to represent this process, which is a process flow diagram (referred to as PFD). Process flow diagrams than text, the production is easier to view and guidance operations. By flow chart , we can easily find in the process of production, duplication and omission of those work areas, these are very help us to improve the generation process, so as to enhance efficiency in the use of industrial equipment.
Classification process flow diagram
Process flow diagram according to different uses, can be mainly divided into three respective categories, namely: Total whole plant process flow diagram (FIG mass balance), the material flow chart (the MBD) and process piping and instrumentation diagram (the PID) .
1, total plant-wide process flow chart
In the actual chemical production process, we need to design a plant-wide total of the flowchart to explain. Between the respective label for plant, raw materials, semi-finished and finished products and contact sequence.
2, a flowchart material
Based on the above overall process flow diagram of the whole plant, the material is a flowchart showing an internal process material flow chart diagram style between the individual shop. We need to show the relevant part of its material and device properties in the flowchart.
3, process piping and instrumentation diagram
Process piping and instrumentation diagrams are based on the basis of material flow chart, but the information it conveys will be more abundant. Required to draw out the valves, piping, instrumentation, and other related symbols in the illustration.
What is the role of the process flow diagram
Process flow chart is a meaningful industrial icon on its role, summarized as follows:
1, factory production guidance
In the factory production process, process planning is the main basis to guide production planning, scheduling, and processing workers to operate. When handle production, often as a determination basis for the process specification. Therefore, the process flow diagram play a special role.
2, provide the basis for production preparation
Factory want to produce a new product, is the need for the relevant process flow diagram as a guide; so that it can standardize operations, improve production efficiency.
How to draw flow chart
Rendering process flow diagram mainly two kinds, one is hand-drawn, one in software rendering.
1, hand-painted
The computer is not popular, people will need to hand-drawn artwork. But in fact, when carried out in universities teaching knowledge, students will be required to manually plot the way.
2, drawing software
Currently on the market there are many software can draw the process flow diagram. Commonly used mapping software are: Figure billion illustration , CAD. Figure billion illustration software built-in rich symbol process, users can easily create easily shown meet the demand.

Process flow diagram symbols
Process flow diagram symbols more, we are illustrated in Figure billion in, you can view detailed related symbols. Commonly used process code can be divided into: pipes and cables, symbols commonly used equipment, pump, heat exchanger, vessels, valves, instruments and the like.
Flow chart template
Depending on the production, processing, equipment requirements, may be composed of a wide variety of process flow in FIG. We conclude from Figure billion part of the classical process flow diagram illustrating the software templates for your use and reference.
