Modular, skid-mounted process equipment—such as CIP systems, bio processors, blowers and dryers, and compressors and pumps—is increasingly common. The following design recommendations will help ensure that your skid-based systems are flexible and easy to integrate, and simplify maintenance:
1. Create interface layer.应用S88与许多不同的环境中OEM equipment units, which all have their own way of handling recipes, create an integration layer for central control, monitoring, and recipe and batch management. Don’t force the OEM vendor to customize his product to your wishes. This creates issues with vendor support, qualification and additional costs, etc. Use the vendor standard, but implement an integration layer to do the specific translation of the unit procedure into the OEM equipment language using the specific required interface (OPC, XML, etc.). The integration layer acts as the only interface between ISA 95 level 2 and level 3.
2.打滑设计技巧。所有的管道插座和入口都应进行自密封,并在滑雪的一侧快速连接,水平弯曲为90度(或45度,如果更方便)。入口和出口应标记有蚀刻或以其他方式永久性的箭头。应访问阀门以从滑雪的一侧取出。如果提供门,则应全面保护并用受控的互锁保护,并在需要时进行自然通风或定向通风。警卫需要足够强大才能实现偶然力量。提供矫正的安全玻璃窗,需要观察仪表或机械动作以进行休闲过程验证或调试。
3. Skid construction.Ensure that the materials used in construction are acceptable for the intended plant environment. Some facilities will not allow wooden skids, for example, and the substitute for this must be approved well in advance.
4. Similar to rafting.防滑安装类似于滚动设备的“漂流”。卷板形成线的元素有很多,但是预处理设备包含了线圈处理程序和矫直机,以及后处理设备,包括焊工,切割机,重击器和堆叠器,都易于更改。卷表可能需要数小时;该作品是重复的,左右索引。当左侧形成时,右侧正在转换。重复和索引需要额外关注的线的元素可能很有趣。索引允许设备以受控方式交换,而无需叉车。
5. Modular design.The best way to design a skid is to lay out the design in the beginning and determine the area required. In the design phase, a layout can be made to determine the best location fit. Although skid designs vary according to the engineer involved with the design of the equipment, the best approach is to provide a modular layout so that in the future changes can be made with the least amount of effort. Modular is the best layout because it makes it possible to change the requirements.
6. Base skid design on components.根据最重要和标准的组件(例如RO单元或其他膜系统的膜数量,或基于鼓风机和储罐的典型容量)创建标准滑冰。确保模拟系统以确定是否允许选择一系列操作。在位于平行或系列的模块中工作以增加容量。
7.容器框架的尺寸。If you want mobile equipment, design and choose the machines that can fit inside a container frame. Some plumbing systems can be preengineered in the frame; install and test these in a dedicated workshop to make sure the quality standards are met. Mount starters and controls on the wall. Install vacuum pump/blower setup plugs in with supplied power only, allowing for plug-and-play replacement of spare units.
8.购买前测试。Thoroughly inspect a demo unit prior to specifying and ordering. Specify parts that you already have access to in network. Drive standardization.
