Definitions & Functions
Centralized lubrication system refers to a system that starts from a lubricating oil supply source and accurately transports a certain amount of lubricating oil or grease to multiple lubrication points according to a certain time or cycle through distributors, distribution pipelines and oil quantity measuring parts. The system is not only responsible for the delivery and distribution of lubricants, but also covers the functions of lubricant regulation, cooling, heating, purification, etc., as well as the indication and monitoring of parameters such as oil pressure, oil level, differential pressure, flow rate and oil temperature.

Types and classifications
Centralized lubrication systems can be divided into various types according to their characteristics and application needs. According to the lubrication pump oil supply mode, there are manual oil supply system and automatic electric oil supply system; According to the lubrication mode, there are intermittent oil supply system and continuous oil supply system; According to the transportation medium, there are dry oil centralized lubrication system and thin oil centralized lubrication system; According to the lubrication function, there are resistance centralized lubrication system and volumetric centralized lubrication system; According to the degree of automation, there are ordinary automatic lubrication systems and intelligent lubrication systems. In addition, there is a hybrid centralized lubrication system that combines the above systems.

How it works
The working principle of a centralized lubrication system usually involves the following steps: first, the oil or grease is pumped out from the supply source; These lubricants are then conveyed to the various lubrication points via distributors and distribution lines; During the conveying process, the oil gauge ensures that the right amount of lubricant is available at each lubrication point; Finally, the system monitors and adjusts the parameters of the lubricant to ensure the effectiveness of the lubrication and the safe operation of the equipment.

Benefits & Applications
The centralized lubrication system has many advantages, such as timing and quantification, automatic and efficient, labor and cost reduction, and prolonging the life of equipment. It can significantly reduce the wear and failure rate of equipment, and improve the operational efficiency and safety of equipment. At the same time, due to the reduction of lubricant waste and energy consumption, the centralized lubrication system also has a certain environmental protection and energy-saving effect. Therefore, it is widely used in wind power, construction machinery, food processing machinery, metallurgical mining, mechanical processing, port machinery, automobile manufacturing, military vehicles, nuclear power plants and other fields.

However, there are some issues that need to be noted with centralized lubrication systems. First of all, it is more costly and may not be cost-effective for some small businesses or occasions with less equipment. Secondly, the system has high technical requirements and requires professional technicians to install, debug and maintain. In addition, the system has centralized control over the lubrication status of the equipment, and if the system fails, it may lead to the lubrication of all equipment being out of control, so regular inspection and maintenance are required.
