Widely used Doppel bearing oil and gas lubrication to help energy saving and environmental protection

When the industry is developing rapidly, low failures, energy saving, environmental protection, and reliable operation of equipment have become the goals pursued by enterprises. The cost of power machinery equipment consumes 50-60 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.

Doppy develops targeted and personalized solutions according to different application occasions of users. 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.


Compared with the traditional lubrication method, the Doppel oil-air lubrication equipment is compact, convenient to connect, and saves space. At the same time, it also simplifies the seal design of the lubrication cavity.
