Sliding bearing lubrication, under what circumstances need throttling?
Save the utility can adjust the lubricant pressure to provide lubricating oil bearing agent with membrane response of the bearing capacity and stiffness, and can maintain a constant, so that the lubricating oil change, lubricating oil can improve the pump like nuclear nuclear power station
For precision, safety, efficiency, power consumption and other high demand occasions, bearings need to use throttling. For example, nuclear power plants, nuclear pumps, large grinders.Compared to liquid lubrication, the steady-state and dynamic characteristics of gas lubrication are poor, so gas lubrication usually has throttling devices.
The function of throttling is to adjust the pressure of the lubricant, so that the lubricant film of the bearing is provided with corresponding bearing capacity and rigidity, and can be kept constant, so that the lubrication is stable, and the lubrication performance is improved.
