摘要： A centrifugal pump pumps fluid containing large or long objects of solid material. Solid parts cause problems with centrifugal pumps in that they both stick to the edge of the vanes of the pump wheel and get in between the pump wheel and the housing and stick to either one of these may cause the pump wheel to slow down or get stuck. Large parts may also form a bridge between two vanes. Objects which have become stuck to and rotate together with the pump wheel easily gather more objects and growth of the aggregate is often very rapid. In all of these cases the flow through the pump is distributed and the capacity of the pump is reduced. These problems are avoided with a centrifugal pump in which the edges of the vanes (11, 12, 13, 14) extend themselves continuously in the direction of the flow from the input adjacent the shaft and at an acute angle thereto to a lower part close to the wall (1-1A) of the housing and forwards in the direction of the flow of the pumped fluid.
摘要翻译：离心泵泵送含有大量或长的固体物质的流体。固体部件会引起离心泵的问题，因为它们都粘在泵轮的叶片的边缘上并进入泵轮和壳体之间，并且粘在这两者之一中可能导致泵轮减速或卡住。大部分也可以形成两个叶片之间的桥梁。已经变得卡住并与泵轮一起旋转的物体容易收集更多的物体，并且聚集体的生长通常非常快。在所有这些情况下，通过泵的流量是分布式的，并且泵的容量减小。利用离心泵避免了这些问题，其中叶片（11,12,13,14）的边缘沿着与邻近轴的输入端的流动方向连续延伸并且以锐角向下延伸到下部部分到壳体的壁（1-1A），并沿泵送流体的流动方向前进。

摘要： Apparatus for providing a mechanical planar seal, as for example for use with a centrifugal pump having a rotating shaft, includes a primary seal formed of a movable first part rotatable with the shaft and a fixed second part or seat, a secondary seal axially spaced along the shaft from the primary seal, an inlet for flushing liquid, an outlet for the flushing liquid and for pump medium that leaks through the primary seal, a collection chamber defined between the primary and secondary seals for flushing liquid and leaking pump medium, and a drain passage connecting the collection chamber and outlet. The collection chamber is divided into at least two portions in liquid communication with each other and with the drain passage by at least one predeterminately-configured wall so as to assure that the flushing liquid is maintained between the primary and secondary seals for an extended period of time for advantageously efficient use of the flushing liquid in lubrication and cooling of the primary seal.

摘要： The present invention is for a conductivity metering device. The invention is primarily for conductivity meters which are used for level gauging of fouled liquids where the fouling materials may cause functioning problems of the metering probe. The probe is intended for metering of the conductivity between the probe body 1 and a tube 14, made from metallic material, in order to determine if there is liquid inside the tube. The probe body 1 is the outer tip of a piston 6 and it may be made as one piece with the piston or as a separate part which is mounted onto the piston. The piston 6 and parts connected thereto are movably mounted in the cover part 15 and the cap 8 by sealing slide bearings 4, 7. When metering does not take place the tube 14 is mostly filled with water at a certain overpressure relative to its surroundings. As the metering piston 6 is kept retracted by an active overpressure between the sealings 4 and 7 liquid is prevented from leaking in.
