P14473: Programmable Mounting Fixture -- Hose Test
/public/

Problem Definition

Project Summary

Waterproof products must undergo testing to ensure that they perform as advertised. The test setup requires a frame to hold the product in question while it is sprayed with water at a set pressure and for a designated amount of time. While the test is in progress the product must be rotated to ensure adequate water coverage over the entire surface. Existing water test rigs consist of frameworks that must be moved manually or of static frameworks that instead require the hose to be redirected to spray different parts of the product. This project will entail the design and fabrication of a programmable mounting fixture capable of securing and rotating a variety of waterproof lighting fixtures while they are being sprayed with water under pressure to ensure their compliance with NEMA Type 4, IPX6, and Marine Hose test Standards. The fixture should be able to accommodate the sizes and weights of the current line of Cooper Crouse-Hinds products. The fixture should have a control that will allow the operator to rotate the fixture with respect to the X, Y and Z axes at a variable speed. The system needs to be highly corrosion resistant and must be standalone. Because of the nature of the testing all electrical components and connections must be waterproof. The expected end result is a working fixture that can be used for in-company testing. The fixture will be thoroughly tested before delivery to the customer. A complete set of documentation will be supplied including an operation and maintenance manual.
