Choose grease or lubricating oil, the starting point of equipment lubrication
In the daily operation and maintenance of machinery and equipment, lubrication is an indispensable link. Whether gears, bearings or other critical components, good lubrication ensures stable operation, reduces wear and extends service life. When choosing a lubrication product, the first step is to determine whether to use grease or lubricating oil.
Greases and lubricants, although they are used for lubrication, but their properties, uses and applications have significant differences. Grease, also known as grease lubricating oil, is a thick, grease-like semi-solid, mainly composed of Base Oil, thickener and additive. It can form a solid oil film between the friction surface, play a good lubrication role, and because of its thick texture, it can also effectively prevent the intrusion of dust and water, play a sealing and protective role. Therefore, the grease is mainly used in occasions that require long lubrication and are not easy to replace, such as sealed bearings, gear boxes, etc.
The lubricating oil is a liquid with strong fluidity, mainly composed of base oil and additives. It can form a thin oil film between the friction surfaces, reduce friction and wear, and also has good cooling and cleaning effects. Due to the good fluidity of lubricating oil, easy to replace and supplement, it is widely used in occasions that require frequent replacement or supplementary lubrication, such as engines, transmissions, etc.
When choosing whether to use grease or lubricating oil, the first thing to consider is the working environment and requirements of the equipment. For example, for closed equipment that requires long-term operation and is not easy to replace lubricants, grease is more suitable because of its good sealing and protection; For open equipment that requires frequent replacement or replenishment of lubricant, lubricating oil is more suitable.
In addition, the operating speed and load of the equipment are also important factors to consider when selecting lubrication products. Under high speed and high load operating conditions, lubricating oil is more advantageous because of its good flow and cooling performance; At low speed and light load, grease can provide a more stable lubrication effect.
Finally, it is also necessary to consider the special requirements of the equipment for lubrication products. For example, some equipment may need to operate in high or low temperature environments, which requires the selected lubrication product to have good high temperature stability and low temperature fluidity; Some special equipment may also require lubrication products with special properties such as corrosion resistance and oxidation resistance.
To sum up, the choice of grease or lubricating oil needs to be considered according to the working environment, operating requirements and special needs of the equipment. Only by choosing the right lubrication products can we ensure the normal operation of the equipment, extend its service life and improve production efficiency. Therefore, in the selection of lubrication, it is necessary to carefully analyze the characteristics and needs of the equipment, and choose the most suitable lubrication products.
