Abstract: A bearing assembly includes a first bearing unit and a second bearing unit for supporting a shaft, in particular a rotor shaft within a centrifugal compressor in which an axial load acts on the shaft in a first or a second axial direction, the second axial direction being opposite to the first axial direction. When the axial load acts in the first axial direction, the first bearing unit is configured to support both an axial load and a radial load and the second bearing unit is configured to support a radial load. Alternatively, when the axial load acts in the second axial direction, the first bearing unit is configured to support a radial load and the second bearing unit is configured to support both an axial load and a radial load.

Abstract: Disclosed is a device for regulating the compression force of a spring-spacer assembly provided in a mechanical shaft seal in a system including a motor and a pump or compressor. The device includes a spacer made from shape memory alloy, a spring in line with the spacer, and a heater proximate the spacer. When heated, the spacer contracts in length, resulting in a decrease in compression force. Also disclosed are systems and methods utilizing the device. The device is particularly useful when starting a pump or compressor to reduce friction in the mechanical seal. Existing mechanical seals can be easily retrofitted with the device.

Abstract: A coupling pin for use in a pump housing, the pump housing including an outer casing and an inner pump liner, the coupling pin being suitable for locating the liner and casing relative to one another, the coupling pin including a shank and a head at one end of the shank. The head includes a cammed surface thereon which is adapted to co-operate with a follower on the liner, and a locating section on a remote or terminal end of the head which is adapted to be positioned against a seat in the outer casing when fitted. The arrangement is such that rotation of the coupling pin causes the follower to track along the cammed surface so as to cause relative movement between the outer casing and the inner pump liner.

Abstract: An oil supply system for a propeller turbine engine includes a first oil circuit for supplying the turbomachine and a second oil circuit for supplying the propeller gearbox and the high-pressure pump associated with a propeller adjusting device. The two oil circuits are integrated into a common oil tank and connected to one another by means of an oil supply line in the flow direction downstream of the first and the second oil conveying pumps in such a way that a limited oil volumetric flow can flow from the first oil circuit into the second oil circuit, and only in this direction, if the pressure difference between the first and the second oil circuits falls below a certain level in the event of a pressure reduction in the second oil circuit. In this way, a sufficiently high initial pressure of the oil is produced at the high-pressure pump, even at low propeller speeds and during transient propeller adjustment processes, so that the function of the propeller adjusting device is not impaired and the high-pressure pump is not damaged. Limiting the oil volumetric flow in the oil supply line connecting the two oil circuits prevents that the turbomachine is inadequately supplied with oil, while oil is being removed from the first oil circuit.

Abstract: An oil-retaining bearing fan structure includes a fan base seat, an oil-retaining bearing and a fan impeller. The fan base seat has a bearing cup on one side. At least one magnetic member is enclosed in the bearing cup. The magnetic member serves to apply a magnetic attraction force to a shaft of the fan structure to make the shaft quickly restore to its optimal operation position so as to reduce wear and lower the noises and vibration of the fan structure in operation. Therefore, the lifetime of the fan structure can be prolonged.
