Grease is now a common consumable in our processing industry, processing industry machinery and equipment after a long time of use there will need to pour grease, so that machinery and equipment can work normally, then for such an important grease have you understood, know the low temperature performance of grease, if you do not know, I come to tell you what is the low temperature performance of grease.

The viscosity of the grease at a certain temperature is the variable that changes with the shear rate, this viscosity is called similar viscosity, the unit is: Pa.s. The similar viscosity of the grease decreases with the increase of the shear rate, but when the shear rate continues to increase, the similar viscosity of the grease close to the viscosity of its base oil will no longer change.

Grease similar viscosity and shear rate change law called viscosity a speed characteristics, viscosity with the shear rate change more significant, the greater the energy loss. Generally can be based on the low temperature conditions of the grease similar viscosity to allow the value of the grease to determine the low temperature use limit.

Low-temperature torque is said to grease in low temperature conditions when the use of low-speed ball bearing blocking the degree of rotation, low-temperature torque can be expressed grease low-temperature use performance, with 9.8N.cm torque measured so that the bearing in lmin turn a week when the low temperature, as grease low use temperature.

Of course, the operation speed of the lubrication part is also an important factor to consider, if the effectiveness of the grease can not meet the operation speed of machinery and equipment, it may happen that the parts because the operation speed is too fast, too much friction, and lead to parts burned. Also consider the method of adding grease and the cost of purchasing it.

The above is the low temperature performance of grease is what to share, if you want to know more information about it, please pay attention to this site.
