In addition to the above classification, the lubrication method can also be divided into lubricating oil lubrication, or thin oil lubrication, grease lubrication or dry oil lubrication, as well as solid lubrication, gas lubrication, etc. according to the type of lubricant supplied.
Dispersed lubrication
It is often used to lubricate dispersed or individual parts of the lubrication points. In dispersed lubrication, it can also be divided into two basic types: full loss (or "one-time oil lubrication") type and circulation type, such as using portable refueling tools (oil pots, oil guns, hand brushes, chlorine sol spray guns, etc.) to manually refuel the oil pool, oil nozzle, oil cup, guide rail surface and other lubrication points, as well as oil rope or oil pad lubrication, splash lubrication, oil ring or oil chain lubrication, etc.
Centralized lubrication
Use a complete set of oil supply devices to supply oil to many lubrication points at the same time, which is often used for the lubrication of gearboxes, feed boxes, complete or complete sets of mechanical equipment and automated production lines. Centralized lubrication systems can be divided into three types of systems according to the oil supply method: manual operation, semi-automatic operation and automatic operation. It can also be divided into full loss system, circulation system and static pressure lubrication system. A total loss system means that the lubricant is not recycled after it is delivered to the lubrication point. It is often used in situations where lubricant recovery is difficult or unnecessary, the amount of oil required is very small, and it is difficult to place an oil pan or oil pool. The lubricant of the circulating lubrication system is delivered to the lubrication point for lubrication and then flows back to the oil tank for recycling. The hydrostatic lubrication system uses an external oil supply device to deliver lubricant with a certain pressure to the hydrostatic support for lubrication.
