What is the difference between the different grades of lithium ester 1 2 3

1. The viscosity is different.

The type of lithium grease is distinguished by its cone penetration, with 3 having the highest viscosity, 2 having a medium viscosity and 1 having the least viscosity. The smaller the size, the less viscous.

2. The taper penetration is different.

The penetration is 310 340;The taper penetration of 2 is 265 295;The taper penetration of 3 is 220 250. The penetration degree indicates the degree of softness and hardness of the grease, and the above is divided by the working penetration range.

3. The role is different.

l Suitable for centralized grease feeding system.

It is suitable for medium speed, heavy-duty machinery and equipment. Such as automobiles, tractor hub bearings, small and medium-sized motors, water pumps and blowers, etc.

It is suitable for mining machinery, automobiles, tractor wheel bearings, large and medium-sized motors and other equipment.

The difference is not very big, just 1 is a little thinner, generally the speed is high, the load is small with dilute, the load is large, the speed is slow with high viscosity, that is, thick.

The classification of grease grades is based on the penetration index, the unit is 1 10mm, the larger the penetration value, the thinner the grease, and vice versa. For grease with the same soap base, the higher the penetration degree, the lower the dropping point temperature.

The use temperature, that is, the dropping point, is different, and the hardness is also different!

It seems that the viscosity is different, (many years, I can't remember clearly).

1) The NLGI consistency classification divides the grease from 000 to 6 into 9 grades, with a difference of 15 units between each grade. Among them, the grease is called semi-fluid grease, which is mainly used for the lubrication of bearings, gears and various friction parts that are not suitable for lubricating oil lubrication, and is becoming more and more viscous, and can be directly applied to the bearing or gear lubrication.

2) Lithium grease is divided into fully synthetic base oil lithium grease and mineral base oil lithium grease according to the base oil, although the lithium base grease produced by synthetic base oil is complex, but it is much better than the lithium grease produced by mineral oil.

1.Introduction of lithium lipids.

Lithium grease is an advanced grease that can be used as a high-speed bearing grease, a high-temperature splash grease, and a fully synthetic gear oil. The manufacturing process of lithium grease is mature, and its lubricating performance is very outstanding, and it is widely used in various industries.

2.The difference between lithium grease No. 1, No. 2 and No. 3.

Lithium grease No. 1, No. 2, and No. 3 refer to the three specifications of lithium grease, respectively. In terms of chemical composition, they are not very different, mainly in terms of performance parameters such as viscosity index, dehydration and oxidative stability.

3.Lithium grease No. 1.

No. 1 lithium grease has good performance in viscosity index, dehydration, extreme pressure, oxidation resistance and extremely low temperature performance, and is suitable for low-speed and heavy-duty or general industrial machinery lubrication.

4.Lithium grease No. 2.

No. 2 lithium grease is better than No. 1 lithium grease in terms of dehydration, oxidation resistance, and extremely low temperature performance, and is suitable for lubrication under high temperature conditions such as high-speed bearings, automatic transmissions, braking systems, and cylinder walls of internal combustion engines.

5.Lithium grease No. 3.

No. 3 lithium grease is better than No. 1 and No. 2 lithium grease in terms of high temperature resistance, extreme pressure resistance, oxidation resistance, dehydration and extremely low temperature performance. It is suitable for high-temperature and high-speed friction parts, heavy equipment gearbox lubrication and locomotive bearings and other high-demand occasions.

6.Precautions for using lithium greases.

When using lithium grease, it is important to note that mixing with other types of grease may reduce lubricating properties, so you should choose the same type of grease. In addition, care should be taken to prevent lithium lipids from entering the ** and eyes during the operation of the fingers.

7.Summary.

In general, lithium grease No. 1, No. 2, and No. 3 all have their own application occasions. When selecting lithium grease, it is necessary to select the corresponding specifications and models according to the actual needs, so as to achieve better lubrication effect.

No. 2 lithium grease and No. 2 lithium grease have different cone penetration, No. 2 is 265-295, the most commonly used, No. 3 is at 220-250, harder, and is generally used in applications that require resistance to water or solid impurities, reducing equipment wear. Sluggish Clan.

The dropping point temperature of No. 2 lithium grease and No. 2 lithium grease is different: the higher the number of dropping points, and the higher temperature of No. 3 than No. 2.

The application of lithium grease No. 2 and lithium grease No. 2 is different; No. 2 is suitable for machinery and equipment with medium speed and medium load. Such as car yard cheats, tractor wheel bearings, small and medium-sized motors, water pumps and blowers, etc. No. 3 is suitable for mining machinery, automobiles, tractors, hub axle covers, large and medium-sized motors and other equipment.
