Integrated System Build & Test
Table of Contents
Team Vision for Integrated System Build & Test PhaseThe intent of this phase was to begin the compilation of subsystems to create what will be the final product after testing and corrections. This means that the kegs will be engineered to act as the fluid containers with full functionality, and electrical components will be mounted to the structure with all tubing, fitting and connections attached.
Test Results Summary
Due to resource constraints, the team will not be able to begin testing prior to the Integrated Systems Build & Test phase demo on October 31, 2017. The team will update this page once the testing has taken place. The team intends to take the week to catch up on lost time and begin testing. Each member will put in more hours than previously in order to assure the product is delivered to the customer on time and of high quality.
Update: November 16, 2017
The team has completed the build phase of the keg washer. There were many delays this term due to order processing and shipment as well as time to complete welding requests from the Brinkman lab.
If the team could have eliminated these risks, the project could have been completed sooner, but this is the nature of an Engineering project. The outside work leaves variation in the time line. The team could not have forecasted these issues and accounted for the time they would have consumed. We are working to make up for lost time by reducing the time for testing.
The customer hand-off is anticipated to occur between December 9 and December 16. Two members of the team will drive down to the brewery and assist in setting up the keg washer in the facility.
This image is a representation of the front view of the keg washer. This is the view the user will have while operating the system. The HMI is visible in the image an is where all prompts will be controlled in order to execute the wash. Under the black cord on the system is a thin steel box that was welded to the structure to protect the pump from any excess water. This should be enough coverage for the pump as it is graded IP65 for water protection.
The second image is the interior of the electrical box. This is a water tight box, which is necessary with the amount of liquids flowing in an out of the system. All electrical components are contained within this box and water tight cutouts in the box allow for the main connections to the solenoids and other components. The electronics are controlled using the HMI.
This image represents the back view of the keg washer. From this view the user can see the solenoids and manifolds which control the fluid flow. There was an addition to the design where check valves have been added in order to control the back flow of fluids throughout the system. The manifolds have been mounted on a thin steel plate extending from the structure for support.
Risk and Problem TrackingThe largest risk encountered during this phase was not meeting the time constraints.
Due to delays in product shipments, some assembly of the product were pushed out further than anticipated. Additionally, no team members were weld-certified at RIT so the welding was completed based on the availability of Brinkman lab employees.
In order to make up for lost time, the team anticipates having to crash the time allotted to testing the fixture and putting in a lot of weekend hours to complete all deliverables.
Plans for next phaseThe project plan has encountered some significant set backs because of some resource issues. The team will try to make up for this, but in the case that that does not happen, the slack time from the beginning will help.
The Mechanical Engineers will continue making adjustments to the structure as testing begins and the Electrical Engineers will make adjustments to their program where necessary and make sure all wiring is done correctly. The Project Manager will work in parallel with the team to continue documentation and complete the major deliverables associated with this including the Technical Paper, Poster, and Final Gate Review.
