    • An improved jet well pump includes a centrifugal pump assembly that is a stamping-welding one and a jet pump assembly. The centrifugal pump assembly includes a pump body and a pump cover, an impeller and a shaft that are disposed in the pump body, it also includes a motor arranged outside of the pump body. The impeller is installed on the shaft and driven by the motor. The jet pump assembly includes a jet pump body, a nozzle installed in the jet pump body and a throat member disposed on the upper end of the jet pump body. The centrifugal pump assembly and the jet pump assembly are communicated with each other by means of an inlet pipe and a return pipe. The upper ends of the inlet pipe and the return pipe are connected with an inlet and an outlet that are arranged on the axial surface of the pump body respectively, and the lower ends are connected with the throat member and the jet pump body respectively. The well pump not only improves manufactural process by simplifying and compacting structure and is convenient for transportation and use, but also reduces the intensity of labor and the cost, saves materials and has no pollution.
    • 改进的喷射井泵包括离心泵组件,其是冲压焊接件和喷射泵组件。 离心泵组件包括设置在泵体内的泵体和泵盖,叶轮和轴,还包括布置在泵体外侧的马达。 叶轮安装在轴上并由电机驱动。 喷射泵组件包括喷射泵体,安装在喷射泵体内的喷嘴和设置在喷射泵体上端的喉部件。 离心泵组件和喷射泵组件通过入口管和回流管彼此连通。 入口管和回流管的上端分别与设置在泵体的轴向表面上的入口和出口连接,下端分别与喉部件和喷射泵体连接。 井泵不仅通过简化和压实结构提高了制造工艺,便于运输和使用,而且降低了劳动强度和成本,节省了材料,没有污染。

    • A rotating flow pump such as a centrifugal pump is provided with a feed pump unit formed as an ejector. The feed pump unit comprises an inlet portion, a nozzle, and a diffuser arranged in succession, and the diffuser is connected to the inlet opening of the flow pump. The inlet portion, the nozzle, and the diffuser of the ejector are situated in a plane perpendicular to the shaft of the flow pump. The diffuser comprises an inner channel of a uniformly increasing flow cross section at least over part of its length. Furthermore the diffuser comprises an outer jacket situated substantially coaxially about the above channel. Thus the jacket is formed in such a manner that a substantially 180.degree. almost mushroom-shaped turning of the flow direction for the liquid flowing through the diffuser is obtained at the same time as a uniformly increasing flow cross section--seen in the flow direction--is obtained within the annular chamber between the channel and the jacket. In this manner the diffusing capacity of the ejector can be very high at the same time as the flow pump takes up relatively little room.
    • 诸如离心泵的旋转流量泵设置有形成为喷射器的进料泵单元。 进料泵单元包括连续排列的入口部分,喷嘴和扩散器,并且扩散器连接到流量泵的入口。 喷射器的入口部分,喷嘴和扩散器位于与流量泵的轴垂直的平面中。 扩散器包括在其长度的至少一部分上具有均匀增加的流动横截面的内部通道。 此外,漫射器包括围绕上述通道大致同轴地设置的外部护套。 因此,夹套的形成方式是在与流动方向相同的流动截面的同时获得流过扩散器的液体的流动方向大致为180度的几乎蘑菇状的转动, 在通道和护套之间的环形室内获得。 以这种方式,喷射器的扩散能力可以非常高,同时流动泵占据相对较小的空间。
