摘要： Systems and methods to help provide lubricant to a bearing in a compressor are disclosed. The embodiments disclosed herein generally are directed to systems and methods to provide a lubricant flow to the bearing, where the lubricant flow relies on the rotation of a shaft of the compressor, so that the lubricant flow can be independent of a power supply.

摘要： The impeller is provided with: a disc section equipped with a tube section, the grip section of which is fixed by thermal deformation to a rotation shaft that is rotated around the axis line, and a main disc body, which is provided on the other end in the axial direction from the grip section and which extends outward in the radial direction of the rotation shaft; and blade sections that protrude from the main disc body in the axial direction. The disc section is provided with a hoop stress-limiting section, the tube section of which extends further towards the other end in the axial direction than the main disc body.

摘要： A centrifugal compressor for compressing a refrigerant vapour in a refrigeration cycle. The compressor comprises an impeller drive shaft supported by first and second radial bearings for rotation within the compressor housing and an impeller assembly including at least one centrifugal impeller wheel mounted on the impeller drive shaft to rotate with the impeller drive shaft. The first and second radial bearings are hydrodynamic fluid bearings in which the bearing fluid is the refrigerant vapour. The compressor further comprises a conduit for supplying a portion of the refrigerant vapour from the impeller assembly to the first and second fluid bearings.

摘要： The turbomachine assembly includes a first turbomachine having an inlet, an outlet and a rotary shaft, a second turbomachine having an inlet, an outlet and a rotary shaft, a transfer duct fluidly connecting the outlet of the first turbomachine to the inlet of the second turbomachine, and a casing housing the turbomachines and the transfer duct; the turbomachines are located adjacent to each other so that the outlet of the second turbomachine is close to the outlet of the first turbomachine and the inlet of the second turbomachine is remote from the outlet of the first turbomachine; the outlet of the second turbomachine has an end portion shaped like a cochlea (i.e. a spiral duct); the transfer duct has an annular shape, and surrounds the end portion of the outlet of the second turbomachine.

摘要： A blower includes an electric motor case, a housing having a housing inlet and a housing outlet between which is defined a flow path for gas, a first impeller adapted to accelerate gas tangentially and to direct it radially outward, and a stationary portion. The stationary portion includes an annular gas flow path of sufficient width to allow a flow of gas therethrough without introducing excessive pressure drop. The stationary portion includes a first stator vane structure defining a plurality of stator vane leading edges, the first stator vane structure located on the second side of the motor and arranged to smoothly direct gas flow along a curved path. The motor case provides a shielding function for the stator vane leading edges from an impeller blade pressure pulse.

摘要： A compressor system is disclosed with a base structure configured to support a compressor. A removable oil reservoir is connectable with the base structure. An oil drain tube is configured to be in fluid communication with portions of the compressor system and the oil reservoir. The oil reservoir is configured to slidingly move relative to the base structure and engage with the oil drain tube in a fluid sealing arrangement.
