Abstract

Hydraulisch angetriebene Membranpumpe mit einer randseitig zwischen einem Pumpenkörper (10) und einem Pumpendeckel (12,14) eingespannten Membran (16,18), die einen getrennte Ein- und Auslasskanäle für ein zu förderndes Medium aufweisenden Förderraum von einem Hydraulikraum (36,38) trennt und von einem hydraulischen Membranantrieb in Form eines oszillierenden Verdrängerkolbens (40) zwischen einer Saughub- und einer Druckhubgrenzstellung hin- und her bewegbar ist, wobei ein stabartiger Schieber (48) auf der hydraulikraumseitigen Seite mit der Membran verbunden und in einer Führungsbohrung (56) des Pumpenkörpers geführt ist, der in eine Saughubgrenzstellung der Membran ein Reservoir für Hydraulikflüssigkeit (42) mit dem Hydraulikraum (36) über ein Saugventil (66) verbindet, wobei der stabartige Schieber einen mit dem Hydraulikraum in Verbindung stehenden Abschnitt der Führungsbohrung (56) über eine Gehäusebohrung (60,61) mit dem Reservoir verbindet, wenn sich die Membran in einer Druckhubgrenzstellung befindet, und ein der Membran zugekehrter Abschnitt des stabartigen Schiebers einen kleineren Durchmesser aufweist, der eine zum Saugventil führende zweite Bohrung (64) freigibt, wenn sich die Membran in der Saughubgrenzstellung befindet zwecks Verbindung des Saugventils mit der Führungsbohrung und über diese mit dem Hydraulikraum.

Figure 00000001
Hydraulically driven diaphragm pump with a diaphragm (16, 18) clamped on the edge between a pump body (10) and a pump cover (12, 14), which has a separate inlet and outlet channels for a medium to be pumped from a hydraulic chamber (36, 38) separates and can be moved back and forth by a hydraulic diaphragm drive in the form of an oscillating displacement piston (40) between a suction stroke and a pressure stroke limit position, a rod-like slide (48) being connected to the diaphragm on the hydraulic chamber side and in a guide bore (56) of the pump body, which in a suction stroke limit position of the membrane connects a reservoir for hydraulic fluid (42) to the hydraulic chamber (36) via a suction valve (66), the rod-like slide over a section of the guide bore (56) connected to the hydraulic chamber a housing bore (60,61) connects to the reservoir when the membrane is in is a pressure stroke limit position, and a diaphragm-facing section of the rod-like slide has a smaller diameter, which opens a second bore (64) leading to the suction valve when the membrane is in the suction stroke limit position for the purpose of connecting the suction valve to the guide bore and via this to the guide bore hydraulic chamber.
