Project for UNO
Sponsor: Lockheed Martin

  1. Project involving the complete design of a power distribution system for a Class I Div. I area. Would involve research into the N.E.C., power distribution, conduit routing, wiring, lighting calculations, etc.
  2. Project involving the design and building of a flow control or mixer system utilizing either a PLC or computer. Project should incorporate safety devices, graphics, and feedback control.

Course Overview

The project will consist of the complete electrical design of an additional Mix Room being installed at an industrial factory. The ingredients to be mixed are hazardous, requiring a system design utilizing Class I Division I regulations. The basic power requirement portion of the project will consist of power distribution systems for all lighting, machine operation and control systems. The supplied power will be from an external power panel fixed to the outside of the room containing both three phase 480V and 208V lines. (Project could be expanded to include power being supplied via a 13.8 KV overhead transmission line, requiring students to design a step down substation.) The students will be required to design all power distribution including lighting, wiring and must meet all specified mixer and controller power requirements. In addition, all designs must meet all National Electric Code regulations. A complete set of drawings outlining all layout, components and an itemized equipment and material cost list is required. The students are to keep in mind that this project is being implemented on a limited budget and the most cost effective implementation is imperative.

The mixer will require a PLC control system that will monitor the ingredient flow, utilizing a flow meter, and control the flow using solenoids and valves. There will be three input ingredients, all being classified as hazardous, producing a hazardous output chemical. Again all electric distribution components and control system components must be designed to meet all code requirements. The ingredients will be combined in a fixed, predetermined ratio with each ingredient input quantity being measured with the utilization of the flow meters. After all ingredients are injected into the vat the mixer will be operated for the specific period of time required to produce the desired chemical output.

The detail, length and job scope can be adjusted as to be appropriate for the 14-week, 3-credit-hr. senior-level project. In addition, it would be possible to expand the depth and complexity of the project to encompass 2 semesters of course work.
