United Equipment Accessories’ rotary union endurance test stand was built entirely in-house for the purpose of conducting accelerated life testing of rotary unions. The stand’s control program uses a test procedure that strictly follows a specified set of testing parameters. Sensors measure the response of the tested elements under simulated conditions for a specific period and for a certain threshold. The endurance test stand sits in a specially designed room that has its own ventilation system, automatic fire suppression, and a two-hour fire rating. Two webcams connected to the network provide 24-hour video surveillance to the endurance test stand.
