Abstract: A fluid machine with variable vanes includes: a case, a plurality of vanes arranged along a circumferential direction of the case; a transmission ring rotatably provided in the case and configured to rotate with respect to the case; a transmission member provided on the transmission ring; and a driving assembly detachably attached to the case and including: a driving shaft; and a connection member connected to the transmission member through a through hole of the case provided at a position corresponding to the transmission member and configured to rotate together with the driving shaft, wherein the connection member is disengageably engaged with the transmission member such that the driving assembly is disconnected from the case through the through hole.

Abstract: A high-efficiency power generation system includes: a combustor configured to generate a circulating fluid by burning a fuel; an expander configured to generate power by expanding the circulating fluid; a power generator configured to generate electricity using the power generated by the expander; a compressor configured to compress the expanded circulating fluid; a pump configured to circulate the compressed circulating fluid; a heat exchanger configured to allow the expanded circulating fluid passing through the expander and the compressed circulating fluid passing through the compressor to exchange heat with each other; and a power transmitter including a driving shaft, and configured to rotate a driven shaft, which includes shafts of the compressor and the pump, to transmit the power generated by the expander to the compressor and the pump.

Abstract: A blade assembly including a rotor; a body portion connected to the rotor and having a space therein; and at least one vibration reduction member provided in the space.

Abstract: An air-cooling system for fluidic machine includes a base frame, a first intercooler arranged above the base frame and in which a fluid for heat exchange flows, an oil cooler arranged adjacent to the first intercooler and in which oil flows, a second intercooler arranged above the base frame to face one of the first intercooler and the oil cooler and in which the fluid for heat exchange flows, an aftercooler arranged adjacent to the second intercooler to face the other of the first intercooler and the oil cooler and in which the fluid for heat exchange flows, and a blower supplying cooling air to a space between the first intercooler and the oil cooler, and the second intercooler and the aftercooler.

Abstract: An oil seal structure and a compressing apparatus including the oil seal structure are provided. The oil seal structure includes a rotating shaft, a bearing, a lower housing portion, an upper housing portion, an assembly surface seal member inserted into a first assembly surface seal groove, and an oil seal member provided in a first seal groove and a second seal groove and including a flange portion, wherein a lower oil receiving portion is formed in the lower housing portion, a first passage groove is formed in the first seal groove, and an oil passage is formed between a bottom surface of the first passage groove and the flange portion.

Abstract: A compressor includes a housing; an impeller rotatably installed in the housing; a guidance unit connected to the housing at a first end of the guidance unit and configured to guide a fluid discharged by the impeller, the guidance unit configured to change a flow direction; and a scrolling unit connected to a second end opposite to the first end of the guidance unit. A width of an opening via which the fluid enters a circular space of the scrolling unit is about 1.5 to about 3.5 times a height of the guidance unit.

Abstract: A sensor signal transmission system includes: at least one wireless sensor disposed in an equipment package and configured to sense at least one type of information; a gateway configured to receive the at least one type of information sensed by the at least one wireless sensor in a wireless manner, and convert the received information into at least one communication signal; a controller configured to control the equipment package by collecting the at least one communication signal input from the gateway; and at least one wireless power supply configured to supply power to the at least one wireless sensor in a wireless manner.
