[China Aluminum Network] Lubrication refers to the addition of lubricant between the relatively moving surfaces of friction pairs of mechanical equipment to form and maintain an appropriate lubricant film. Centralized lubrication refers to the complete oil supply unit supplying oil to equipment lubrication points simultaneously or on demand. The use of concentrated lubrication can reduce frictional resistance, reduce surface wear, cool down, prevent corrosion, absorb shock, and seal.
Wire thread inserts are helically coiled fastening devices that provide permanent, wear-resistant screw threads that exceed the strength of most parent material; the inserts are designed to protect tapped holes against failures due to stripping, seizing, corrosion, and wear.
Threaded inserts are typically used when the object in which a threaded fastener is being installed is made of a soft material. For hard materials, a screw or bolt can be often driven into the object without the need for a threaded insert. A simple solution is to use a threaded insert.

To make the wear of the friction pair small, it is necessary to maintain a proper clean lubricating film on the surface of the friction pair, i.e. maintain a constant supply of oil between the friction surfaces to form an oil film, which is generally the preferred characteristic of continuous oil supply (constant flow).
However, some components require only one or two drops of oil per hour. It is very difficult for general lubrication equipment to continuously supply fuel in proportion to this requirement. In fact, oversupply of oil is just as detrimental as the lack of oil (for example, some bearings generate additional heat when over-provided). A large number of experiments confirmed that discontinuous but regular fuel supply is the preferred method. Therefore, when continuous oil supply becomes unsuitable, an economical cycle system can be used. The system of this type is to make constant amount of lubricant oil supply to the lubrication point continuously for a predetermined period of time, so that the friction pair maintains a proper amount of oil film.
In general, the friction pair on most machines is suitable for lubrication with a periodic lubrication system. The friction pair with continuous lubrication system is limited to when the machine is running continuously and the load is very high, for example: punch presses, large-scale boring mills, portal milling machines, gear hobbing machines, etc.
Therefore, in choosing the type of lubrication system, we must remember:
1. In most cases, a periodic lubrication system should be used.
2, too much and too little lubricating oil is equally harmful to the friction pair.
3, the use of periodic lubrication system should be used to control the amount of friction parts of the fuel supply to the friction pair, use the continuous lubrication system should use the control to control the amount of friction of the fuel supply.
The system consists of the following parts:
1. Lubrication pump - Provide lubrication media as needed.
2, the distribution of components - the amount of lubricant distribution on demand.
3. Accessories - consists of pipe joints, flexible hoses (or rigid rigid pipes), distribution blocks, etc.
4, control - from the electronic control and pressure switches, level switches and other control components. Lubrication pump works according to predetermined requirements, controls the starting time and shutdown time of the lubrication pump and the system, monitors the system pressure, alarms the level of the tank, and displays the working status of the system.
The centralized lubrication system can be divided into the lubricant lubrication and the grease lubrication according to the difference of the lubrication medium: According to the system distribution elements, it can be divided into a resistance lubrication system, a volumetric lubrication system, a progressive lubrication system, and an oil-air lubrication system.
