摘要： PROBLEM TO BE SOLVED: To provide an impeller for a gas compressor having excellent durability even in the case of compressing gas including solid particles without increasing any cost. SOLUTION: The impeller 3 is provided for the gas compressor for compressing the gas including the solid particles, and has a hub part 10 and a plurality of blades 12 erecting from an outer circumference surface of the hub part 10 in a substantially radial direction, wherein the gas is compressed by rotation of the hub part 10 and respective blades 12 around a center axis. For each blade 12, a wear resistant film 20 is provided only at a gas inlet part. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：即使在压缩包括固体颗粒的气体的情况下也能提供具有优异耐久性的气体压缩机的叶轮，而不增加任何成本。解决方案：叶轮3设置用于压缩包括固体颗粒的气体的气体压缩机，并且具有轮毂部分10和从轮毂部分10的外圆周表面竖立的多个叶片12，其基本上径向方向，其中通过轮毂部分10和相应的叶片12围绕中心轴的旋转来压缩气体。对于每个叶片12，仅在气体入口部分设置耐磨膜20。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fan assembly minimizing accumulation of contamination such as dust on a working air fan an extending lifetime of the fan assembly.
SOLUTION: A shaft supported by a bearing is driven by the motor assembly. The shaft penetrates the bracket and extends into a shroud assembly. A first fan is connected to the shaft and is provided in a first chamber. A second fan is connected to the shaft and is provided in a second chamber. Air is made flow through the fan assembly by rotation of the first and the second fan by the shaft. Dust is almost prevented from adhering on blades of the first and the second fan during operation. Consequently, crushing and accumulation of uneven dust generating excessive vibration and reducing lifetimes of the bearing and a brush can be prevented.

摘要翻译：要解决的问题：为了提供一种风扇组件，其最小化在工作风扇上的灰尘等污染物的积聚，从而延长风扇组件的使用寿命。
解决方案：由轴承支撑的轴由电机组件驱动。轴穿过支架并延伸到护罩组件中。第一风扇连接到轴并设置在第一室中。第二风扇连接到轴上并设置在第二室中。空气通过第一和第二风扇由轴旋转而流过风扇组件。在操作期间，几乎防止灰尘附着在第一和第二风扇的叶片上。因此，可以防止产生过度振动的不均匀的粉尘和轴承和刷子的寿命减少的积聚。版权所有（C）2008，JPO＆INPIT
