摘要： A hydrogen compressor system comprises a hydrogen generating apparatus for generating hydrogen gas to be supplied to a fuel cell vehicle and a multi-stage reciprocating compressor for pressurizing the hydrogen gas generated by the hydrogen generating apparatus. High pressure tanks having maximum use pressure of 20 MPa are connected to middle stages of the multi-stage reciprocating compressor by gas supplying lines via valves. By opening/closing the valves, hydrogen gas in the high pressure tanks can be selectively supplied to the middle stages of the multi-stage reciprocating compressor.

摘要： A reciprocating compressor includes: a low-pressure stage compression part for compressing low-pressure working gas supplied from a supply source; two high-pressure stage compression parts for compressing the working gas compressed by the low-pressure stage compression part at two stages; and a crank mechanism for driving the low-pressure stage compression part and the high-pressure stage compression parts. The two high-pressure stage compression parts each have a plunger and a cylinder and are arranged on both sides of the crank mechanism in such a way as to extend coaxially opposite to each other. The low-pressure stage compression part has a piston and a cylinder and is located in the middle of the two high-pressure stage compression parts. The crank mechanism, the low-pressure stage compression part, and the two high-pressure stage compression parts are substantially located in the same plane.

摘要： A reciprocating compressor has a plurality of compressor stages each compressing a working gas by combining a cylinder and a plunger, and its discharge pressure exceeds 40 MPa. The compressor stage has a packing seal which seals a shaft of the plunger, and oil pouring means which pours a lubricating oil to the packing seal. A filter removes the lubricating oil poured by the oil pouring means from the working gas. In the filter, a first element using micro glass fiber and a second element using functional activated carbon are coaxially mounted. These two elements are included together in a pressure container. According to the above described construction, in the compressor at a high pressure exceeding 40 MPa, quality of the discharge gas can be kept and the compressor can be made compact.

摘要： In a fluid machine such as multistage centrifugal compressor, the pressure of a working fluid is raised with the rotation of a impeller. A shaft sealing device is mounted at the end of the rotary shaft in order to prevent the working gas of the raised pressure from leaking out of the fluid machine and then polluting the surroundings. In a case where the fluid machine operates to rotate at high speed, a labyrinth sealing device is employed for the purpose of reducing a frictional loss in the shaft sealing device. The labyrinth sealing device includes a plurality of stages of labyrinth fins which are formed on a casing or the rotary shaft, and a layer of abradable coating to-be-bitten which is formed in the surface part of the rotary shaft or the casing opposing to the labyrinth fins. The clearances between the labyrinth fins and the rotary shaft or the casing are made narrower on the low-pressure side of the labyrinth sealing device than on the high-pressure side thereof. Thus, the fluid machine is run with the minimum clearance. Moreover, even when the coating layer has been lost in contacting the labyrinth fin or by peeling off, the labyrinth fin on the low-pressure side acts as a labyrinth seal.
摘要翻译： 在诸如多级离心压缩机的流体机器中，随着叶轮的旋转，工作流体的压力升高。 轴密封装置安装在旋转轴的端部，以防止升高的压力的工作气体从流体机器泄漏，然后污染周围环境。 在流体机械高速旋转的情况下，为了减少轴封装置的摩擦损失，采用迷宫式密封装置。 迷宫式密封装置包括形成在壳体或旋转轴上的多级迷宫式散热片和形成在旋转轴的表面部分或与壳体相对的壳体上的可磨损涂层层 迷宫鳍。 迷宫式散热片与旋转轴或壳体之间的间隙在迷宫型密封装置的低压侧比在其高压侧更窄。 因此，流体机器以最小间隙运行。 此外，即使当涂层在迷宫式翅片接触或者剥离时已经失去了，低压侧的迷宫式翼片也作为迷宫式密封。

摘要： A centrifugal compressor comprises a centrifugal impeller and a vaned diffuser. The diffuser includes a pair of diffuser plates and a plurality of guide vanes arranged between the pair of diffuser plates in a circular cascade manner. The guide vanes are equal in leading-edge radius to each other, but are different in length from each other. At least one short guide vane is arranged between the adjacent long guide vanes. The total number of the guide vanes is more than the number of blades of the impeller. A throat is formed in only a part of flow passages between the guide vanes.
