What is the role of the vacuum pump in using lubricants?

We all know that vacuum pumps need to use lubricants. What is the role of the lubricants? Let's take a look.

Lubricating oil is used in various types of machinery to reduce friction and protect the mechanical and processing parts of liquid lubricants, mainly for lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricants account for 85% of all lubricated materials, and there are many types of products. Now the world uses about 38 million tons. The general requirements for lubricants are:

(1) Reduce friction and anti-wear, reduce frictional resistance to save energy, reduce wear and tear to prolong mechanical life and improve economic efficiency;

(2) Cooling, requiring the friction heat to be discharged outside the machine at any time;

(3) Sealing, requiring leakage, dust and anti-mite;

(4) Anti-corrosion and anti-rust, it is required to protect the friction surface from oil deterioration or external erosion;

(5) Clean and rinse, it is required to clean the friction area scale;

(6) Stress dispersion buffering, dispersing load and mitigating shock and shock absorption;

(7) Kinetic energy transfer, hydraulic system and remote control motor and friction stepless speed change.

Lubricating oils generally consist of two parts, a base oil and an additive. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, and give some new properties. It is an important part of lubricating oil.
