What is the difference between a turbine’s oil baffle and an oil seal?
An oil baffle ring is usually a metal ring fixed to the shaft, or it can be made of a softer material and also mounted on the shaft. An oil seal is typically installed at the shaft end to prevent oil from leaking out
The oil baffle is usually made of copper or aluminum and is mounted on the shaft, rotating together with it, while the oil seal is generally installed on the cylinder block and remains stationary, preventing oil from leaking out.
Upstairs, what you mentioned are all the oil shields and oil seals for ordinary pumps; the oil shield of a turbine is installed on the bearing shell, while the oil seal is placed on the bearing housing cover.
What was said upstairs is correct; I won’t repeat it here.
The oil baffle ring is primarily used to ensure a stable lubricating oil pressure in the radial and thrust bearings, while the oil seal is mainly intended to prevent the lubricating oil inside the bearing housing from leaking outside through the shaft.
