grease and lubricating oil
do you really know what lubricating grease is? What is lubricating oil?
grease is composed of different soap bases mixed with appropriate amount of lubricating oil according to its purpose, which can be understood vividly as a piece Sponge filled with lubricating oil.
Lubricating oil = base oil + additive (oil liquid flow) -large fluidity, wide distribution area, uniformity, permeability, low adhesion, thin oil film, low resistance. Z1z
base oil is the main component of lubricating oil, which determines the basic performance of lubricating oil. Additives can make up for and improve the performance of base oils, and give some new properties. They are an important part of lubricants.
Grease = base oil + additive + thickener (grease paste solid) -can withstand extreme pressure and high impact, maintain good lubrication and good adhesion, but there is a possibility of resistance. The selection principle of
industrial grease The basic performance and main selection principle of
grease is the cone penetration, which is used to classify the consistency of the grease. The penetration of
is a commonly used index for controlling the consistency of various greases. It is used to indicate the performance of the grease entering the friction point and the index of the degree of hardness of the grease.
1. When the bearing that uses grease is subjected to a large load and a low speed, a grease with a small cone penetration should be selected.
2. On the contrary, when the load is small and the speed is high, the grease with large penetration is necessary.
3. In the wide range of high and low temperature, light load, high speed and low low temperature, and other special requirements, synthetic grease should be used.
