Turbine Lubrication Methods

What are the common methods used to lubricate turbines that drive auxiliary equipment?

Choose the proper lubrication method for turbines used to drive auxiliary equipment:

• Grease nipples
• Oil impregnated bushings
• Ring-oiled bearings
• Self-lubricated sealed bearings

Answer:

Turbines used to drive auxiliary equipment can be lubricated by various methods, including grease nipples, oil-impregnated bushings, ring-oiled bearings, and self-lubricated sealed bearings.

Turbines used to drive auxiliary equipment are usually lubricated by various methods, depending on the specific application. Some common options include:

1. Grease nipples: These are used for lubricating components such as bearings and gears. Grease is forced into the component through a nipple or fitting.
2. Oil impregnated bushings: These bushings are made from a porous material that contains oil. As the bushing rotates, the oil is released to lubricate the moving parts.
3. Ring-oiled bearings: These bearings have a ring or reservoir that stores oil. As the bearing rotates, the oil is distributed to the contacting surfaces for lubrication.
4. Self-lubricated sealed bearings: These bearings are pre-lubricated and sealed to retain the lubricant for an extended period of time.

The choice of lubrication method depends on factors such as the speed, load, and operating conditions of the equipment.
