When the industry is developing rapidly, low failures, energy saving, environmental protection, and reliable operation of equipment have become the goals pursued by enterprises. 50% to 60% of the cost of power machinery and equipment is energy, and the effective utilization rate of energy is about 30% on average, and the friction and wear of machinery account for 10%-20%. It can be seen that it is of great significance to reduce the frictional resistance of the contact surface by reducing power consumption and reducing friction and delaying mechanical wear. Oil-air lubrication technology as a new type of lubrication can effectively solve the above problems. <br /> Doppely develops targeted and personalized solutions according to users’ different applications. Oil-air lubrication is applied to the processing of various friction pairs such as bearings, chains, gears, and a variety of complex parts, and has achieved good economic and social benefits. Oil-air lubrication is the formation of a gas-liquid two-phase flow between dry and clean compressed air and lubricating oil. The compressed air pushes a small amount of lubricating oil to the lubrication point to provide continuous and reliable lubrication for the friction pair. At the same time, the oil and gas have a certain pressure, which can form a positive pressure in the bearing housing cavity, which can prevent external dirt from entering the friction pair, and play a sealing role to prevent dust from entering the clean cavity. It also has a cleaning effect on the surface of the open friction pair. <br /> Compared with the traditional lubrication method, the Doppy oil-air lubrication equipment is compact, convenient to connect, save space, and also simplifies the seal design of the lubrication cavity. <br />
