Enterprises that use industrial lubricants (industrial grease refining) have relatively concentrated machinery and equipment, so purposeful and targeted technical exchanges will be more necessary. This is also the main form of pre-sales technical services.
Basic performance
The basic performance and main selection principle of industrial lubricating oil (industrial grease refining) is viscosity, so it must be introduced first. GB/T3141-94 is the ISO viscosity classification of industrial liquid lubricants, which is equivalent to the international standard ISO3448-1992 "Industrial Liquid Lubricants-ISO Viscosity Classification". Generally speaking, in the working conditions of medium speed, medium load and not too high temperature, use medium viscosity lubricating oil; in the working conditions of high load, low speed and high temperature, choose high viscosity lubricating oil or add extreme pressure resistance Lubricating oil for abrasives; low-viscosity lubricating oil is selected under low load, high speed and low temperature conditions; synthetic lubricant is selected under wide high and low temperature range, light load and high speed, and other special requirements. Oil
The basic performance and main selection principle of lubricating grease is the cone penetration, which is used to divide the grease consistency grade. Therefore, it should also be introduced to users. Cone penetration is a commonly used indicator for controlling the working consistency of various greases, which is used to indicate the performance of the grease entering the friction point and the softness and hardness of the grease. - j, t* Y* P7 K; J Generally speaking, when the bearing with grease is subjected to a large load and a low speed, the grease with a small cone penetration should be selected. On the contrary, when the load is small and the speed is high, the grease with a large cone penetration should be selected. Synthetic grease should be used in wide high and low temperature range, light load, high speed and low temperature, and other special requirements.
