2. Hydraulic tappet - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_tappet

   A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine. Conventional solid valve lifters require regular adjusting to maintain a small clearance between the valve and its rocker or cam follower. This space prevents the parts from ...

3. List of additives used for fracking - Wikipedia

   The differences between additives for fracking in different countries are the type of chemicals used (hazardous, non-hazardous), the disclosure of chemicals and the composition of fracturing fluid. In 2010, Halliburton announced the creation of food additive based hydraulic fracturing fluid in response to calls for transparency and demand for a ...

5. Hydraulic fluid - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_fluid

   Because industrial hydraulic systems operate at hundreds to thousands of PSI and temperatures reaching hundreds of degrees Celsius, severe injuries and death can result from component failures and care must always be taken when performing maintenance on hydraulic systems. [5] Fire resistance is a property available with specialized fluids.

6. Artificial lift - Wikipedia

   en.wikipedia.org/wiki/Artificial_lift

   Artificial lift is the use of artificial means to increase the flow of liquids, such as crude oil or water, from a production well. Generally this is achieved by the use of a mechanical device inside the well (known as pump or velocity string) or by decreasing the weight of the hydrostatic column by injecting gas into the liquid some distance down the well.

8. Dry lubricant - Wikipedia

   en.wikipedia.org/wiki/Dry_lubricant

   Dispersion of solid lubricant as an additive in oil, water, or grease is most commonly used. For parts that are inaccessible for lubrication after assembly, a dry film lubricant can be sprayed. After the solvent evaporates, the coating cures at room temperature to form a solid lubricant.

9. Automatic transmission fluid - Wikipedia

   en.wikipedia.org/wiki/Automatic_transmission_fluid

   Lifetime automatic transmission fluids made from higher-quality base oil and an additive package are more chemically stable, less reactive, and do not experience oxidation as easily as lower-quality fluids made from lower-quality base oil and an additive package. Therefore, higher-quality transmission fluids can last a long time in normal ...
