PMMI REVIEW - Lubrication

What are the functions of lubricant in a mechanical drive system

• Minimizes friction, delays wear and tear, absorbs heat, prevents corrosion
• Eliminates friction, causes wear and tear, generates heat, attracts corrosion
• Increases friction, accelerates wear and tear, traps heat, promotes corrosion
• Reduces friction, prevents wear and tear, dissipates heat, protects against corrosion

What are the types of lubricant in a mechanical drive system

• Liquid lubricants, Aged oils, Hot greases

• Air-based lubricants, Green Slime

• Oil-based lubricants, grease, dry lubricants, solid lubricants
• Water-based lubricants

what is an application used for oil based lubricant

• Engine lubrication in vehicles
• Window cleaner
• Hair conditioner
• Cooking oil

what is an industrial application used for grease lubricants

• Heavy machinery, automotive equipment, and manufacturing machinery
• Medical devices
• Agricultural tools
• Household appliances

What is a dry lubricant

• A dry lubricant is a lubricating substance that reduces friction between surfaces without the need for a liquid carrier.
• A dry lubricant is a type of liquid lubricant
• A dry lubricant is used to increase friction between surfaces
• A dry lubricant is only effective in wet environments

what is an advantage of using solid lubricants

• Low cost and availability
• Enhanced durability and lifespan
• High temperature and pressure resistance
• Improved efficiency and performance

What are three types of oil lubricants

• castor oil, coconut oil, Penzoil

• olive oil, Cooking oil, Black oil

• What is oil?

• mineral oil, synthetic oil, semi-synthetic oil

What is mineral oil

• Mineral oil is a type of vegetable oil
• Mineral oil is a solid substance
• Mineral oil is used for cooking purposes
• Mineral oil is a colorless and odorless oil derived from petroleum.

what is an advantage of using a synthetic oil

• Decreased fuel efficiency
• Shorter engine lifespan
• Better engine protection, longer lifespan, and improved performance in extreme temperatures
• Reduced performance in extreme temperatures

what is one advantage of using a semi synthetic oil

• Less protection and performance than conventional oil

• Increased engine wear
• Less environmental impact
• Cheaper cost than full synthetic oil
