Orifice restrictor hydrostatic bearings

WitrynaNowadays, the most commonly used active pressure feedback restrictor for hydrostatic bearing is membrane type, in which a thin and flexible metal sheet serves as the key component to meter the hydraulic oil flow precisely. However, the membrane type pressure feedback restrictor is not quite suitable for extremely heavy load. WitrynaThe high-pressure liquid CO2 was supplied to the bearing, and the orifice restrictor was used for the flow control device. We selected the orifice diameter providing the maximum bearing...

Witryna10 wrz 2024 · Restrictor is a constant-pressure compensating element, and it affects the performance of the hydrostatic bearing. At a constant supply pressure, lubricating oil flow compensation element automatically adjusts oil pressure to adapt different loads and restrictor change by making pressure drops. Witryna28 lis 2016 · This type of restrictor can support much heavier loads than the membrane type and is suitable for the bearings in large machine tools. The novel design has two significant features: the first is the orifice restrictor which effectively circumvents the influence of fluctuating oil temperature. shofuso house and gardens philadelphia pa https://hickboss.com
