摘要:
A lubricant supply system includes first and second tanks, each including an internal volume that is divided into a first portion and a second portion. The first portion of the internal volume of the first tank and the first portion of the internal volume of the second tank are configured to alternate supplying a liquid refrigerant to a machine. A pump is in fluid communication with the second portion of the internal volume of the first tank and the second portion of the internal volume of the second tank. The pump is configured to vary a pressure of a gas in the second portion of the internal volume of the first tank and the second portion of the internal volume of the second tank.
摘要:
A sliding bearing, e.g. journal bearing, including at least two bearing elements the bearing surfaces of which are slidably supported with respect to each other. At least one of the surfaces is provided with a first type of cavity which may comprise a lubricating substance, the first type of cavity being defined by a specific range of geometric properties. At least one surface is provided with at least a second type of cavity which may comprise a lubricating surface, the second type of cavity being defined by geometric properties which are different from the geometric properties of the first type of cavity.
摘要:
A method for lubricating a rolling element bearing by an ultra low viscosity volatile fluid comprises injecting a liquefied fluid flow into the bearing, lubricating rolling contacts between the rings and the rolling elements of the bearing by the liquefied fluid, providing a flow restriction for the liquefied fluid so as to maintain at least part of the fluid at a pressure which is above the evaporation pressure which is defined by evaporation of the fluid at the temperature or temperatures which prevail(s) in the bearing.
