Hybrid wet-dry face seal seat
Abstract:
A wet-dry face seal seat includes a main body having a mating face configured to mate with a sealing member and an outer diameter surface, and defining a pool feed passage that extends to the mating face and a cooling hole that extends to the outer diameter surface. The wet-dry face seal seat further includes an oil capture scoop extending from the main body and defining an oil volume radially inward from the oil capture scoop and in fluid communication with the pool feed passage and the cooling hole, the oil capture scoop having a radial distance that allows oil to flow through the cooling hole in response to oil flow from an oil jet being below a threshold value and through the pool feed passage in response to the oil flow from the oil jet reaching or exceeding the threshold value.
