Classification according to the nature of the project (1) design of new projects New project design, including the design of new products and the design of products using new technology or technology. Such design is often provided by the research and development unit of the basic design, and then by the engineering research department according to the actual situation of the plant to make engineering design. (two) repeated construction project design; Due to the needs of the market, some products need to build production device, due to the specific conditions of the new plant is different from the original, that is, the size of the product and process specifications are the same, or required by the Engineering Department of design. (three) modification design of existing equipment; Some of the old production device of the quantity and quality of the products can not meet the requirements of customers, or due to technical reasons, raw materials and energy consumption is too high and the lack of competition ability, must carry on the transformation of old devices, including the effect of getting rid of the yield and quality of bottleneck, the optimization of production process control, and improve the comprehensive utilization rate of energy and local process or equipment renewal etc..
