Hydrostatic bearing lubrication with high pressure technology

In hydrostatic bearings external pumps fill the oil pockets of the slide bearings by high pressure with a constant oil flow. This ensures that shaft and bearing don't have direct contact at any time. Due to the constant full lubrication fluid friction is created, which is lower than the solid friction.

Hydrodynamic Lubrication (HL): Theory and Definition

Hydrodynamic lubrication is a term that defines a situation in which two rubbing surfaces are separated by a thin film of a lubricant. This situation is often beneficial and lubrication is used to reduce friction and/or wear of rubbing solids with the aid of liquid (or semi-solid) lubricant .

Development of hydrostatic jacking unit for sleeve bearings

In these cases, it is possible to utilize a hydrostatic jacking unit, a device that separates the surfaces regardless of the running speed. This greatly improves the service life of the sleeve bearings and consequently, the reliability of the generator.

Fluid bearing - Wikipedia

Hydrostatic bearings are externally pressurized fluid bearings, where the fluid is usually oil, water or air, and the pressurization is done by a pump. Hydrodynamic bearings rely on the high speed of the journal (the part of the shaft resting on the fluid) to pressurize the fluid in a wedge between the faces.

Lubrication of hydrostatic bearings: Wepuko PAHNKE

With more than 200 installations across the world, Wepuko PAHNKE pumps are widely used for the lubrication of hydrostatic bearings. Our pumps are designed to meet the high performance and reliability required for this application, as the hydrostatic bearings need to be lubricated at very high pressures – up to 21,800 psi.

4. Mechanical Design IEEE

Sleeve Bearing (cont.) • Cons – May require supplemental cooling method • High speed • High ambient temperature • High loads – May require forced lubrication (High thrust load or hydrostatic jacking for slow roll) – High cost for smaller sizes – Susceptible to oil leaks – Dependent on circulating oil system in some applications

Hydrostatic bearing lubrication with high pressure

A hydrostatic slide bearing has an active lubrication circuit. High pressure pumps are creating an oil film between the shaft and the bearing surface before start up and during operation. URACA pumps are generating realiable the required oil pressure for these bearings.

Oil Whip - an overview | ScienceDirect Topics

Lubrication System Bearings. Sleeve (hydrodynamic journal) bearings support the turbine rotor and generator. Jacking oil (oil lift) is provided during startup and shutdown so the weight of the rotor will not cause the shaft to contact the bearing surfaces. The jacking oil also reduces the starting load on the turning gear.
