Abstract

A pump for pumping hydraulic fluid has a body (3) with an upper (1) and a lower (2) cover. The body and lower cover house bearings which support the shaft (4) which carries the rotor (5). The upper end face of the rotor an undulating surface with depressions receiving fluid from an inlet passageway in the upper cover. Sliding blades (6) are pressed against the rotor end face by springs (9) and, as the rotor rotates, they drive the fluid out of the depressions into an outlet passageway in the upper cover. USE/ADVANTAGE - Pump for hydraulic fluid with low level of operating noise.

Description

Das ist eine Druckpumpe für Drucköl, sie ist von einem elektrischen Motor angetrieben. Sie pumpt bei einer Drehung weniger Öl bei hohem Druck und bei dem gleichem Debit. Für eine größere Menge Öl zu erreichen wird sie mit großen Drehgeschwindigkeiten angetrieben, ohne je welche Nachteile. Das Pumpenrad kann in 2 Stufen angefertigt werden, um 2 verschiedene Mengen Öl für jede Seite zu erhalten.This is a pressure pump for pressure oil, it is an electrical one Motor driven. It pumps less oil with one turn at high pressure and with the same debit. For a bigger one It will reach a lot of oil at high speeds driven, without any disadvantages. The pump wheel can be Stages are made up of 2 different amounts of oil for each To get page.

Die Pumpe macht keinen Lärm und vibriert nicht. Sie ist leicht und auch einfach herzustellen. Sie ist nicht in großer Größe, ist ökonomisch und kann weit und vielfach verwendbar sein. Die Pumpe kann aber auch in verschiedenen Größen hergestellt werden, sie ist auch vorteilhaft im Preis.
Die Pumpe besteht aus:The pump makes no noise and does not vibrate. It is light and easy to manufacture. It is not large in size, is economical, and can be widely and widely used. The pump can also be made in different sizes, it is also advantageous in price.

Claims (2)

1. Die Druckpumpe für Drucköl kann Hydraulikmaschinen und Hydraulikanlagen antreiben und setzt sich aus: Pumpenkörper, Pumpenrad, Welle, Oberdeckel und Unterdeckel zusammen.1. The pressure pump for pressure oil can hydraulic machines and hydraulic systems drive and consists of: pump body, impeller, shaft, Upper cover and lower cover together. 2. Die Druckpumpe für Drucköl nach Anspruch 1 erzielt einen hohen Druck dadurch, daß das Pumpenrad mit einem wellenförmigem Ring versehen ist, so daß der entstandene Druck radial auf das Radialkugellager übertragen wird, wobei sie auch in einer kleineren Form bzw. Größe ist.2. The pressure pump for pressure oil according to claim 1 achieves a high pressure in that the pump wheel is provided with a wave-shaped ring, so that the resulting pressure is transferred radially to the radial ball bearing is, although it is also in a smaller shape or size.
