Abstract: The present disclosure relates to a multiple-capacity centrifugal compressor, which includes a plurality of capacity-control mechanisms. Each of the capacity-control mechanisms includes an inlet guide vane and an outlet diffuser, so that the multiple-capacity centrifugal compressor provides a flexible control strategy. In addition, the present disclosure further provides a method for controlling the multiple-capacity centrifugal compressor that effectively adjusts and controls the capacity-control mechanisms by coarsely adjusting the inlet guide vanes and combined with subsequently adjusting the outlet diffusers.

Abstract: An assembly of a lubrication system for fluid machinery includes a transmission shaft, an oil-injection insulating ring and a labyrinth ring. The transmission shaft defines axially power and passive sides. The power side includes a body unit having first and second bearings. The oil-injection insulating ring located between the first and second bearings sleeves the transmission shaft and connects a fuel-supply looping having outer and inner rings. The outer ring has at least one first hole communicatively connected with the fuel-supply looping. The labyrinth ring having first and second axial ends has outer diameters tapering from the second axial end to the first axial end. The first and second axial ends face the power and passive sides, respectively. A circumference of the labyrinth ring includes circular grooves to form a circumferential step-like structure. The labyrinth ring sleeves the transmission shaft and is embedded into the body unit.
