摘要： The inlet and/or outlet edge of a blank which is to be converted into the vane of an impeller for use in a centrifugal pump is reinforced by providing an exposed surface of the blank with a pair of contiguous recesses which extend along the edge and the deeper of which is immediately adjacent to the edge. The recesses are then filled with metallic armoring material by cladding so that some of the surplus extends beyond the recesses and/or beyond the edge. In the next step, the surplus of armoring material is removed by one or more material removing tools, together with a portion of the blank in the region of the edge so that the exposed surface is provided with a fresh edge which is defined by the armoring material.
摘要翻译：要转化为用于离心泵的叶轮的叶片的坯料的入口和/或出口边缘通过为坯料的暴露表面提供一对沿着边缘延伸的连续凹部而加强，其深度更靠近边缘。然后通过包层填充金属铠装材料，使得一些剩余部分延伸超出凹部和/或超出边缘。在下一步骤中，通过一个或多个材料去除工具将剩余的铠装材料与边缘区域中的坯料的一部分一起移除，使得暴露的表面设置有由铠装限定的新鲜边缘材料。

摘要： A floating-ring seal in a seal chamber is disposed on a pump casing at said end of a housing on the side remote from said pump. The seal chamber is isolated from the pump side by a contact seal element that is seated close to a rotating pump part. The seal chamber has a cooling circuit that is preferably filled with a fluid that is identical to the pumping medium. The seal chamber is separated from pumping medium by the seal element. A pressure compensation device is disposed in the region of the seal element in case fluid leaks from the seal chamber. The pressure compensation device fills the seal chamber with pumping medium to compensate for the leaked fluid.

摘要： A multi-stage centrifugal pump wherein a casing surrounds an impeller and a fluid flow guiding insert in each pump stage. The casing is made of a ferritic material, and the inserts are made of an austenitic material. The casing defines with each insert a first clearance wherein a cylindrical surface of the casing is surrounded by a cylindrical surface of the respective insert so that the width of the clearance increases in response to heating of the inserts and of the casing at the respective first clearances. The casing further defines with each insert a second clearance which is disposed radially outwardly of the respective first clearance and wherein a frustoconical surface of the casing surrounds a complementary frustoconical surface of the respective insert so that the width of each second clearance decreases in response to heating of the casing and of the inserts at the respective second clearances. The width of the first clearances is zero or close to zero within a relatively low first range of temperatures, and the width of the second clearances is zero or close to zero within a relatively high second range of temperatures.
摘要翻译：一种多级离心泵，其中壳体围绕每个泵级中的叶轮和流体导流插入件。外壳由铁素体材料制成，插入件由奥氏体材料制成。壳体限定每个插入件具有第一间隙，其中壳体的圆柱形表面被相应插入件的圆柱形表面围绕，使得间隙的宽度响应于插入件和壳体在相应的第一间隙处的加热而增加。壳体进一步限定每个插入件的第二间隙，该第二间隙位于相应的第一间隙的径向向外，并且其中壳体的截头圆锥形表面围绕相应插入件的互补的截头圆锥形表面，使得每个第二间隙的宽度响应于加热而减小在相应的第二间隙处的套管和插入件。第一间隙的宽度在相对低的第一温度范围内为零或接近于零，并且第二间隙的宽度在相对高的第二温度范围内为零或接近于零。
