Design of a Rotary Union For Coolant Transfer to Radar System
Özet
In this thesis, a rotary joint for cooling fluid transfer to the radar system is developed. The design and analysis to meet the specified technical requirements were verified by tests. In dynamic sealing tests, the sealing, friction, and life performances of PTFE-based seals with ENP and HVOF coatings under different temperature and pressure conditions were investigated. It has been shown that the coating on the AISI4140QT steel rotor using WC/Co/Cr 86/10/4 powder by HVOF method can provide sealing without abrasion in long-term use.
