年产2000吨埋地排污PVC管材车间工艺设计(3)

In the content of the energy conversion, through extrusion molding machine and mold parts energy balance calculation, cooling water and chilled water dosage, and further to determine the specific usage. Through the economic accounting, we can estimate the cost of this design.
In workshop process design, lists the technological factors into consideration such as safety, environmental protection, and has been clear about the personnel arrangement, etc. This design also gives full consideration to the personnel safety and environmental protection issues. In the process of production, production personnel should strictly comply with operation procedures, completes the safety protective measures, and often participate in related training, understand the relevant information.
The content of the final workshop layout design, simple workshop layout requirements and principles are introduced. And for the design of specific workshop arrangement made a brief description. According to the annual output of 2000 tons sewage pipe buried plant. In this design, the workshop is a single-layer workshop. Plant size (length x width x height) is 10m to 18m to 6m. Rectangular plant to plant general layout, economical use of land, convenient equipment arrangement, easy to arrange transport and gateway, there are more walls provide for the use of natural lighting and ventilation design.

1 绪论
1.2 设计的目的及意义
1.2.1 设计的目的
（1）合适的塑料埋地排污管材质
在市政雨、污水管道工程中，选择合适的管材对工程的施工进度、质量、造价以及环境效益有着较大的影响。不同的材料会在排污管抗压，耐腐蚀，排污通畅度和密封性方面有着不同的能力，选择一种取材方便，价格适宜，性能优良的材料是设计最为关键的地方。
（2）可行的使用工艺流程
拥有一个良好地工艺流程可以得到性能更加优良且价格更加合适的产品，一条工艺流程除了需要必须的设备和流程规划外还要考虑合理地车间布置，环保和节能灯问题，这样才能降低成本，获得性价比高的管材。
（3）更好的管材材料配方设计
配方设计，就是根据产品的性能要求和工艺条件合理地选用原材料，确定各种原材料的用量和配比关系。一个好的配方就是于混料设备、挤出设备、模具相匹配，并生产出的管材性能高、质量良好，综合成本又较低，这样产品性价比才高。年产2000吨埋地排污PVC管材车间工艺设计(3):http://www.youerw.com/huaxue/lunwen_946.html
