How many kinds of process design 100

The process flow diagram refers to the schematic diagram used to illustrate the reaction process or chemical processing, and the process flow diagram provides valuable insight into the step-by-step sequence in the analysis of the movement of products and people. The process flow diagram mainly uses the expression of graphic symbols, which can clearly express the structure of each part of the process and the operation process of the process.

There is a set of special graphics and symbols based on industry standards to draw process flow diagrams, including pumps, centrifuges, filters, motors and other equipment involved in the manufacturing and production process, flow meters, temperature and air machines and other instruments, pipelines and connecting lines and valves. The use of these symbols makes it possible to simplify and understand long and complex processes.

Process flow diagrams are generally divided into the following three types:

1. Program flow chart.

The scheme flow chart is the first step in the design of the process flow chart, also known as the total process flow chart or material balance chart of the whole plant. In the scheme flow diagram, a series of equipment (filling name and tag) of the production process and the flow of process materials (indicated by a solid line with arrows) are included in the scheme flow diagram, which describes the process of the production process as a whole. The drawing of the scheme flow diagram is generally not strictly specified, and it is the basis and reference outline for the subsequent design stage.

2. Material flow chart.

On the basis of the above-mentioned scheme flow chart, the material flow diagram adds the data representing the type, flow, flow direction, and equipment characteristics of each material to describe the specific flow of the materials in the process.

3. Process piping & instrument diagram (pid-piping & instrument diagram).

The P&I diagram is based on the material flow diagram and uses uniform graphical symbols to describe in more detail how the pipeline connects the process equipment and how the process works.

Hello, I am happy to serve you: the process flow is written like this, 1. Determine the process flow according to the process requirements. 2. The process requirements should be transformed into process flow through processing process parameters.

The final performance of the process flow is the process flow. Therefore, the complete process flow includes: 1) the production process flow.

2) Each process control elements, process parameters, work instructions, inspection requirements and records. 3. The complete process flow is a process document. The production process is the regulation that enterprises must strictly abide by and implement when engaging in the products they produce.

It should be formulated and written in the order of production, from beginning to end. That is, from 1, raw material procurement requirements, 2, the processing of semi-finished products, (including the number of feeding, processing equipment, temperature control, pressure degree, processing time, etc.) 3, the technical performance indicators of each part, 4, the finished product inspection quality standards, 5, the finished product packaging regulations. From beginning to end, each process of production must have its own process regulations to ensure the smooth progress of the product.

What are the three principles of safety?

Hello, dear, thank you for taking the time to wait for me<>1. Ensure safety: Effective safety measures should be taken in the production process to ensure the safe operation of machinery and equipment and reduce the occurrence of accidents. 2. Protect the environment

In the production process, the crude emission of the chain of harmful substances should be controlled to reduce the pollution to the environment. 3. Improve efficiency: In the production process, the efficiency of the production wheel should be improved, the production quality should be improved, the production cost should be reduced, and the economic benefits of the enterprise should be improved.

The process flow is the "processing flow" or "production flow". It refers to the whole process of continuous processing in sequence from raw material input to finished product output through certain production equipment or pipelines. The technological process is determined by the production technical conditions of the industrial enterprise and the production technical characteristics of the product.

A complete process usually includes several processes. For example, in the masonry project, it is generally necessary to go through the process of mixing mortar, brick immersion, priming, tiling, flat joint, surface cleaning and so on. It can be seen that the basic content of the process is that workers use labor tools to change the shape, size, position, composition, performance, etc. of labor objects to make them the expected products.

Production process refers to the method and process in which workers use production tools to continuously process various raw materials and semi-finished products through certain equipment and in a certain order in the production process, and finally make them into finished products. The principles are: technologically advanced and economically reasonable.

Because factors such as equipment production capacity, precision and worker proficiency are very different in different factories, the processes developed by different factories may be different for the same product; Even the same factory may do different processes at different times.

The production process is the combination of elements in the production process of the product from raw materials to finished products. It includes six aspects: input resources, activities, interaction of activities (i.e., structure), output results, customers, and value. Taking the beer production process as an example, the input resources include raw materials (malted rice), and the activities and the interaction between activities include various reactions and changes caused by the auxiliary support of personnel and equipment, and finally the results (beer) can be output and pointed to a certain customer, and the product production finally has corresponding value.

1. Clarify the main factors of process design.

The problem that process design solves: what products to produce; how it is produced; what kind of equipment and tools are used; What kind of processing method is used.

1. Production equipment.

In the design of the process, the load of the equipment should be taken into account, so that the capacity of the equipment can be balanced.

When producing batches in economical batches, one of the main problems is adapting the selected processing method to the existing plant model. Sometimes, the number of existing equipment of a certain model and specification will affect the process design. The process is designed in such a way that it sometimes causes a certain type of machine to be overloaded with more than the production capacity.

In this case, the processing method had to be changed, and even if the manufacturing cost was increased, it was necessary to switch to a different type of machine. Therefore, it is necessary to maintain close contact with the production control department, which is in charge of the load on the existing equipment.

Existing equipment is not necessarily used in the process design. When a new idea warrants the acquisition of new, more efficient equipment to implement, the continuation of existing equipment will hinder the idea of a new process method. The output of one component may not be enough to economically compensate for the investment in the purchase of new equipment, and when the process of the other part of the component is changed accordingly, the adoption of new equipment becomes economically justified, so that the overall manufacturing cost can be reduced.

Attention is paid to the continuous improvement of the machine tools and equipment used to manufacture the products.

The load is a critical criterion for determining whether the amount of work that is currently in progress plus the amount of work expected to be invested in the future is a critical criterion for excess production capacity or whether the production task exceeds the production capacity.

2. Product quality.

Product quality has a certain impact on process design. After the product quality level is determined, the product designer should stipulate it on the standard drawings. In this way, through the bill of materials, parts list, assembly drawings and parts drawings, as well as the project delivery conditions, the full quality requirements of the assembly and parts can be clearly understood in the process design, so that the most economical manufacturing methods and equipment to ensure the quality requirements of the parts can be selected.

The dimensional requirements, machining surface requirements and other aspects of the performance of the parts must meet the capabilities of various types of machine tools and processing methods. The mechanical condition of the equipment must be carefully inspected to determine whether it can achieve the specified performance of the machined parts. With the help of the application of statistical methods and the study of machine engineering capabilities, it is possible to estimate in advance the level of machining quality that can be achieved by the equipment selected by the design or process department.
