    • PURPOSE: A diaphragm pump system is provided to minimize the number of parts by installing a spool valve and a change-over valve, to simply connect a pump to a compressed air/liquid supply structure, to obtain a pumping system having a diaphragm pump, and to double the input/output pressure ratio. CONSTITUTION: A diaphragm pump system is composed of diaphragm pumps(11,13,14,17) and a pressure intensifier for receiving working fluid compressed from a supply. The pressure intensifier increases the pressure of the working fluid over supply pressure and generates a pumping stroke of a pump for making pump output pressure over the supply pressure of the working fluid by feeding the working fluid of increased pressure to the diaphragm pump. If the pump has the input/output pressure ratio of 1:1, the pressure of an output line of the pump is two times as much as the supply pressure of the working fluid for the pressure intensifier.
    • 目的:提供隔膜泵系统,通过安装滑阀和换向阀来最小化部件数量,以简单地将泵连接到压缩空气/液体供应结构,以获得具有隔膜泵的泵送系统, 并使输入/输出压力比增加一倍。 构成:隔膜泵系统由隔膜泵(11,13,14,17)和用于接收从电源压缩的工作流体的增压器组成。 增压器增加工作流体的压力超过供给压力,并且通过将增加的压力的工作流体供给到隔膜泵而产生泵的泵送冲程以使泵输出压力超过工作流体的供应压力。 如果泵的输入/输出压力比为1:1,则泵的输出线的压力是压力增加器的工作流体的供给压力的两倍。

    • PURPOSE: A web tensioning device is provided to supply tension being non-changeable to the radius of a supply reel and the loosening speed of a wrapping web, to improve better than the result of a simple supply reel brake, and to easily work and reduce manufacturing cost than a system accompanying various brake tests for the supply reel. CONSTITUTION: A device for tensioning a web(22) as a plastics web dispensed from a shuttle in a wrapping apparatus is composed of the wrapping apparatus including an unlimited track positioned around wrapped objects, the shuttle traveling on the unlimited track and dispensing the web, a pair of rollers(23,24) covered with resilient materials to keep a constant tension in the web with forming a nip, a resilient covering of the rollers compressed in the nip, and the web supplied between the nip of the rollers. The speed at which web is dispensed is varied as the shuttle progresses around the track and is decided according to the shape of the track and the wrapped objects.
    • 目的:提供卷筒纸张紧装置,以提供与供带盘的半径不可更换的张力和卷筒纸的松动速度,以便比简单的供带盘制动器的结果更好地改善,并且易于工作和减少 制造成本比伴随供应卷轴的各种制动试验的系统。 构成:用于张紧卷筒纸(22)作为在包装设备中由梭子分配的塑料纤维网的装置由包装设备构成,该包装设备包括位于包裹物体周围的无限轨道,梭子在无限轨迹上行进并分配纸幅, 用弹性材料覆盖的一对辊(23,24),以通过形成辊隙来保持幅材上的恒定张力,在压区中压缩的辊的弹性覆盖物以及在辊的辊隙之间供给的幅材。 卷筒纸分配的速度随着梭子在轨道周围进行而变化,并且根据轨道和包裹物体的形状来决定。
