The time when the pressure in the main line increases and lubricant is supplied to the lubrication point. The two can be carried out at the same time or with a lag in time. In some lubrication systems, the pressure drop after the pressure increase is essential for the function of the lubrication system. The value of the pressure increase is determined by the sum of the resistance between the oil source and the friction point. In some lubrication systems, the lubrication pulse time is not completely consistent with the oil pump running time (see 5.1, 5.2, 53). The time required to produce the necessary pressure drop in order for the distributor to achieve mechanical and hydraulic action. The time from the start of pressure reduction to the start of the next pressure rise in the main line (see Chapter 5).

After the lubricant passes through the friction point, it flows back to the oil tank through the return line for reuse. It is suitable for parts that can not only reduce wear but also take away part of the heat generated by the friction point. After the lubricant flows through the friction point, it does not return to the oil tank for reuse. The operation of the lubrication system is performed manually. The time of manual operation must be such that all lubrication points obtain the specified volume of lubricant or the lubrication system completes a working cycle. After the operation of the lubrication system is started manually (for example, button operation), subsequent actions are automatically realized. When all lubrication points obtain the specified volume of lubricant or the lubrication system completes a working cycle, it stops automatically (see Chapter 5). The operation of the lubrication system is started by time control or machine cycle control and subsequent actions are automatically realized. The lubrication system stops automatically when all lubrication points have received the specified volume of lubricant or the lubrication system has completed a working cycle (see Chapter 5).

Lubricating oil particles are transported with the help of gas carriers; the particles are condensed through condensation nozzles and supplied to various lubrication pointsCentralized lubrication system
Oil-gas lubrication is a centralized lubrication system that uses compressed air to deliver a certain amount of lubricating oil to the lubrication points
A centralized lubrication system composed of several lubrication systems is divided into spray lubrication and oil injection lubrication according to the method of injecting lubricant into the friction points. Both methods are independent of the type of centralized lubrication system. The method of spraying the lubricant on the lubrication point by means of compressed air. The method of spraying the lubricant on the friction point. The centralized lubrication system is equipped with a rotary or reciprocating lubrication pump and an oil tank according to the lubricant (lubricating oil or grease). The pump that delivers the lubricant relies on the change of the closed working volume. The lubrication pump driven by an electric motor is marked with a ×× pump device. In the centralized lubrication system, lubrication pumps without motor drive (for example, with transmission devices such as shaft extensions or levers) such as gear oil pump devices, multi-gear oil pump devices, screw oil pump devices, vane oil pump devices and multi-plunger oil pump devices are usually used. They are marked with ×× pumps. In the centralized lubrication system, plunger pumps, multi-plunger pumps, etc. are usually used. The change (increase or decrease) of the working volume is achieved by the reciprocating oil pressure component. The reciprocating lubrication pump generally used in the centralized lubrication system is the change (increase or decrease) of the working volume of the plunger pump is achieved by the rotating oil pressure component. The rotary lubrication pumps commonly used in centralized lubrication systems are gear pumps, screw pumps, vane pumps and cycloid rotor pumps
