    • A system for conditioning drilling fluid includes a conditioning device having a first conduit configured to receive the drilling fluid, a flow restriction disposed adjacent the first conduit, the flow restriction comprising a fluid inlet and a fluid outlet, an impact plate disposed downstream of the flow restriction, a first chamber disposed between the flow restriction and the impact plate, and a second chamber disposed downstream of the impact plate, wherein the first chamber is fluidly connected to the second chamber. A method for conditioning drilling fluid using a conditioning device, includes pumping a drilling fluid through a flow restriction, accelerating the drilling fluid into a mixing chamber, subjecting the drilling fluid to elongational shearing, decelerating the drilling fluid against an impact plate, subjecting the drilling fluid to impact shearing, and emptying drilling fluid from the mixing chamber.
    • 用于调节钻井流体的系统包括调节装置,其具有构造成接收钻井流体的第一导管,邻近第一导管设置的流动限制器,流动限制器包括流体入口和流体出口,设置在流动下游的冲击板 设置在流量限制器和冲击板之间的第一腔室以及设置在冲击板下游的第二腔室,其中第一腔室流体地连接到第二腔室。 一种使用调节装置调节钻井液的方法,包括通过流动限制泵送钻井液,将钻井液加速到混合室中,对钻井液进行伸长剪切,将钻井液减压到冲击板上, 流体冲击剪切,并从混合室排空钻井液。

    • A liquid fuel collecting and damming assembly located in a vehicle fuel tank to aid the intake of fuel to the engine by elevating the level of fuel about the fuel inlet particularly when the liquid level in the tank is relatively low. The assembly provides an open-ended cylindrical wall which is supported on the fuel tank bottom so that the inlet to the fuel line extends through the resultant open top so as to extend downward toward the bottom. A fuel return conduit extends through the collector assembly's wall and has an outlet end portion spaced vertically upward from the inlet portion so that fuel is discharged therethrough into the collector assembly and enters at an elevated level. The fuel supply in the collector assembly remains at the elevated level with respect to fuel in the tank at a low level condition due to the raised outlet portion of the return conduit.
    • 一种位于车辆燃料箱中的液体燃料收集和阻塞组件,用于通过提高燃料入口附近的燃料水平,特别是当储罐中的液位相对较低时,有助于向发动机吸入燃料。 该组件提供一个敞开的圆柱形壁,其被支撑在燃料箱底部上,使得燃料管线的入口延伸通过所得的开口顶部,以向下延伸到底部。 燃料返回导管延伸穿过收集器组件的壁并且具有从入口部分垂直向上间隔开的出口端部分,使得燃料通过其排出到收集器组件中并以升高的水平进入。 收集器组件中的燃料供应由于回流管道的升高的出口部分而在低水平状态下相对于罐中的燃料保持在升高的水平。
