    • An upper shackle assembly for a steel pump jack for a wood pole includes a u-shaped shackle component to receive the wood pole. The assembly includes a crank handle that extends through the shackle component and engages the pole to lower the pump jack down the pole. The assembly includes a brake attached to the shackle component to engage with the pole if the crank handle fails. A method for installing a steel pump jack to a wood pole includes the steps of placing a u-shaped shackle component about the wood pole. There is the step of closing a brake with the shackle component to engage with the pole if a crank handle fails. There is the step of extending the crank handle through the shackle component to engage the pole. A steel pump jack.
    • 用于木杆的钢泵千斤顶的上部卸扣组件包括用于接收木杆的u形钩环部件。 该组件包括一个曲柄手柄,该手柄延伸穿过该钩环部件并接合该极点,以将该泵压头向下降低。 组件包括附接到钩环部件的制动器,如果曲柄手柄失效则与制动杆接合。 将钢泵千斤顶安装在木杆上的方法包括将u形钩环部件放置在木杆周围的步骤。 如果一个曲柄手柄出现故障,那么这个步骤就是用钩环部件闭合制动器,以便与杆接合。 具有通过钩环部件延伸曲柄手柄以接合杆的步骤。 钢泵千斤顶。

    • A vacuum cleaner includes a first housing defining a cyclonic airflow chamber and a second housing defining a main suction opening that is in communication with an inlet of the cyclonic chamber. A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters said main suction opening, passes through said cyclonic chamber, and passes to an outlet of said suction source. A substantial portion of particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber. A main filter assembly, preferably including filter medium comprising polytetrafluoroethylene (PTFE), is located in the cyclonic chamber so that a suction airstream moving from the main suction opening to the inlet of said suction source by way of the cyclonic airflow chamber passes through the filter medium thereof after said airstream moves in a cyclonic fashion within the cyclonic airflow chamber to remove residual particulates from the suction airstream before it leaves the cyclonic chamber. A HEPA filter can be provided to filter the suction airstream exhausted through the outlet of the suction source prior to the airstream being discharged from the vacuum.
    • 真空吸尘器包括限定旋风气流室的第一壳体和限定与气旋室的入口连通的主吸入口的第二壳体。 抽吸源具有与旋流室的出口连通的吸入气流入口,并且建立进入所述主吸入口的吸入空气流,通过所述旋风室,并且通过所述吸入源的出口。 当所述吸入气流以气旋方式移动通过旋风室时,夹带在吸入气流中的大部分微粒被分离。 优选包括聚四氟乙烯(PTFE)的过滤介质的主过滤器组件位于旋风室中,使得通过旋风气流室从主吸入口至所述吸入源的入口移动的吸入空气通过过滤器 所述气流在气旋气流室内以气旋方式移动,以在离开旋风腔室之前从吸入空气流中除去残留的微粒。 可以提供HEPA过滤器,以在气流从真空排出之前过滤通过吸入源的出口排出的吸入空气。
