摘要： PURPOSE:To prevent penetration of water and to improve draining ability by a method resistance of an air flow is suppressed by forming a recess or a protrusion part along the direction of the flow of air. CONSTITUTION:A centrifugal multivane fan 20 comprises a bottom plate 2 by which at least the lower parts of a plurality of blades disposed in a peripheral direction are fixed; and a hold ring to fix the upper parts of a plurality of the blades. A scroll-form case 7 consists of a side plate, an upper plat, and a lower plate. Protrusions 73, 74, 75, 76, and 77 protruded inward upward from the inner wall of the lower plate of the case 7 are extended in a direction extending along the direction of an air flow flowing out in a centrifugal direction through a gap between the adjoining blades. Since the protrusions 73, 74, 75, 76, and 77 are formed along the direction of the flow of air, the degree of disturbance of the flow of air delivered through a gap between the blades is low and since water is guided in a direction in which the protrusions are extended, the flow of water drops about to flow to the rotation center of the fan is regulated.

摘要： Hydrogen gas compression systems that each include a multistage centrifugal compressor in which each stage has an inlet-to-outlet pressure rise ratio of about 1.20 or greater. In one embodiment, the multistage compressor includes six high-speed centrifugal compressors driven at a speed of about 60,000 rpm. The compressor has an output of more than 200,000 kg/day at a pressure of more than 1,000 psig. The compressors for the compression stages are distributed on both sides of a common gearbox, which has gearing that allows axial thrusts from the compressors to be handled effectively. Each stage's compressor has a unique impeller, which is secured to a support shaft using a tension- rod-based attachment system. In another embodiment, the multistage compressor is driven by a combustion turbine and one or more intercoolers are provided between compression stages. Each intercooler is cooled by coolant from an absorption chiller utilizing exhaust gas from the combustion turbine.

摘要： A pump and method for pumping a gas are disclosed. The pump comprises: a pump housing element and a further element; one of the pump housing and the further element comprising a helical protrusion extending towards the other element, the other element comprising at least one liquid opening. The helical protrusion, pump housing and further element form a path from a gas inlet to a gas outlet. The helical protrusion has an axial cross section that is wider at its attached end than it is at its free end. The pump housing and further element are mounted rotatably with respect to each other; and the at least one liquid opening is configured such that liquid output from the at least one liquid opening forms a liquid blade, the liquid blade being operable to drive gas along the path from the gas inlet to the gas outlet on rotation of one of the elements.

摘要：回転中空ハウジングと独立回転タービンを備えた遠心式ガス圧縮機は、キャピラリーチューブ内の気泡を圧縮し、液体ドレーン(場合によっては液体リサイクラ−)からエネルギーを回収する。ハウジングは、タービンを備えた内部スプールを回転可能に保持する。キャピラリーチューブに供給される気液エマルジョンは、スプール内の環状液体溜まりの半径方向遠位環状領域に圧縮気液エマルジョンを生成する。圧縮ガスは液体溜まりを出て、運び去られる。溢れ出た液体内のタービンブレードのエッジがタービンを駆動し、角速度/運動量を回収エネルギーとしてシャフトトルクに変換する。ブレードで捕捉された液体は、キャピラリーチューブの入力にリサイクルされる。
