The main measures to reduce wear include: 1) Reasonably selecting the materials for the friction pairs used in combination； 2) Determine reasonable roughness and hardness values for the part surface ； 3) Use a lubricant to achieve liquid lubrication or mixed lubrication ； 4) Replace sliding contact with rolling contact ； 5) Improve its wear resistance through surface strengthening of the parts and application of surface coatings.
This question should be: “What are the main measures to reduce frictional losses in pipeline transportation?” ”
The main measures to reduce wear include: 1) Reasonably selecting the materials for the friction pairs used in combination； 2) Determine reasonable roughness and hardness values for the part surface ； 3) Use a lubricant to achieve liquid lubrication or mixed lubrication ； 4) Replace sliding contact with rolling contact ； 5) Improve its wear resistance through surface strengthening of the parts and application of surface coatings.
1) Select the materials for the friction pair in a suitable manner； 2) Determine a reasonable roughness value for the part surface ； 3) Use lubricating oil and extreme pressure additives with brightening agents to form a boundary film on the friction surfaces ； 4) Replace sliding contact with rolling contact ；
1) Reasonably select the materials for the paired friction pairs (such as steel against bronze)； 2) Determine a reasonable roughness value for the part surface ； 3) Use lubricating oil and extreme pressure additives with brightening agents to form a boundary film on the friction surfaces ； 4) Replace sliding contact with rolling contact ；
The main measures to reduce mechanical friction are: 1) selecting appropriate materials for the friction pairs to be used together (such as steel paired with bronze); 2) determining an appropriate roughness value for the surfaces of the parts; 3) using lubricants and extreme pressure additives
1. Conduct targeted redesign of the steam turbine； 2. Address nozzle losses and reduce the roughness of the nozzle surface ； 3. Reduce friction by modifying certain components to improve the efficiency of the turbine.
1. Use high-quality lubricant for lubrication; of course, the lubricant must meet the applicable conditions and requirements. 2. Change the type of friction; if it is sliding friction, it can be changed to rolling friction. 3. Minimize the pressure at the contact surface between the two objects or as a result of their contact
