Description

Kugelkolbenpumpe Bei den bekannten Isugelkolbenpumpen scInvingen bzw. rotieren wie bei allen derartigen Kapselwerken in einem Gehäuse Maschinenteile, die durch Dichtungsflächen Saug- und Druckräume voneinander trennen. Nutzen sich nun durch längeres Arbeiten diese Dichtungsflächen ab, so geht die volumetrische Leistung der Pumpe stark zurück.Ball piston pump With the well-known Isugel piston pumps scInvingen resp. Rotate machine parts as in all such capsule works in a housing, which separate suction and pressure chambers from one another by sealing surfaces. Use yourself Now, by working for a long time, these sealing surfaces are removed, the volumetric one goes The performance of the pump decreased significantly.

Diese Tatsache trifft besonders bei den bekannten Flügelpumpen zu, die z. B. .auch bei reinem Wasser sehr schnell in ihrer Leistung zurückgehen. Man hat daher bereits vorgeschlagen, durch besondere Metalle von höherer Festigkeit und guten Laufeigenschaften bei reinen Flüssigkeiten, z. B. sandfreiem Wasser, tragbare Betiiebszeiten zu erhalten.This fact applies particularly to the known vane pumps, the z. B.. Decrease in their performance very quickly even with pure water. Man has therefore already proposed using special metals of higher strength and good running properties with pure liquids, e.g. B. sand-free water, portable To maintain operating times.

Fördert man jedoch, wile beispielsweise bei Hausbrunnenanla-gen, sandhaltiges Wasser, oder handelt es sieh um das Fördern von sandigem Fluß- oder Teichwasser, werden die Kapselpumpen, insbesondere die bekannten Kugelkolbenpumpien, einem schnellen Verschleiß unterworfen.However, if, for example, in domestic well systems, sand-containing materials are promoted Water, or is it a matter of pumping sandy river or pond water, the capsule pumps, especially the well-known spherical piston pumps, are fast Subject to wear and tear.

Es ist nun neuerdings eine Gummiart (entwickelt worden, die mit hoher Festigkeit verformt werden kann und fest auf Metallflächen aller Art haftet. Düese Gummiart hat sich beispielsweise bei d-,r Lagerung von Schiffswellen bestens bewährt und besitzt bei Wasserschmierung einen erstaunlich niedrigen Reibungskoeffizienten von etwa o,oo8.A type of rubber has recently been developed (with a high Strength can be deformed and firmly adheres to metal surfaces of all kinds. Nozzle Type of rubber has proven itself, for example, in the bearing of ship shafts and has an astonishingly low coefficient of friction with water lubrication of about o, oo8.

Dd:e Erfindung besteht nun darin, Kapsel-,verke, insbesondere die 1%ugelkolbenpump°n, aus diesem Material herzustellen, derart, daß man ein inn°r,-s metallisches Gerippe mit dem verschleißfesten Gummi in Formen vergießt und mit entsprechend hohen Drücken umpreßt. Auf diesle Weise kann man verschleißfeste Gehäuse- und Innenteile, wie Kugelkeile und Kugelmittelstücke, herstellen und die Lieblensdauer -derartiger Pumpen um ein Mehrfaches verlängern' Dia, man diesies Material mit hoher Präzision pressen und seine Oberfläche auch schleifen oder sionstwve veredeln kann, ist die erforderliche Grundlaxe für Leim besseres, wirtschaftlicheres Erzeugnis durch,die Erfindung gegeben.Dd: e invention now consists in capsule, verke, especially the 1% ugelkolbenpump ° n, made of this material, in such a way that one inn ° r, -s metallic framework with the wear-resistant rubber cast in molds and with accordingly high Press around. In this way, wear-resistant housing and internal parts, such as ball wedges and ball centerpieces, and create the favorite duration-such Pumps extend the length of the slide many times over, you can use this material with high precision can press and also grind or sionstwve its surface is the required base layer for glue better, more economical product through that Invention given.
