Definitions
- the invention refers to a, preferably designed as a well water pump, Piston pump with a reciprocating piston in a cylinder and a piston integrated filter piston.
- Pseudo-continuous piston pumps take over in a first stroke resiliently biased inlet valve, a fluid in a pumping chamber to this Finally, to compress in a second cycle and an exhaust valve issue.
- Drilling water pumps take heavily contaminated drilling water at low Press and on separate outputs both filtered and drilled water Solids concentrated drilling water at higher pressures available. By the strong solid content in the drilling water is a regular backwash of the filter necessary to avoid permanently adding to it.
- a piston pump includes a for cleaning the fluid executed filter which is immovably fixedly disposed in the cylinder. A backwash the filter is not possible.
- a piston pump having the features of the preamble of claim 1 is known from Patent DE 673 894 C known.
- the object of the invention is in the realization of a filtering piston pump for strong solids added fluids.
- the piston pump with a, in a cylinder with a self-closing inlet valve to a pump room, sealing back and forth moved piston one with this resiliently biased, axially limited sealing movable upstream filter piston, which with the piston an independent closing exhaust valve is formed.
- the piston increases by its axial outward movement of the Pump space, which creates a negative pressure when the exhaust valve is closed, which is the fluid mixed with solids via the inlet valve opened thereby into the pump chamber flows in.
- a second stroke reduced by its axial movement Her the pumping space and the fluidized fluid is compressed, thereby the upstream filter piston is moved against the bias on the piston and the Outlet valve opens, which filtered through the filter piston and through the piston condensed purified fluid can flow out.
- the pumping function with a filter function combined.
- the piston pump has an independently closing concentrate outlet valve to the pump room, which at a by adding the filter resulting Overpressure in the pump chamber discharges the fluid concentrated with solids.
- the piston pump also highly fluidized fluids and with respect to the Solid load highly fluctuating fluids can be cleaned.
- the self-closing exhaust valve is also wegumble end closing, whereby at a shortly before the bottom dead center of the Her movement axially on Cylinder abutting filter piston the exhaust valve closed, a return flow of the cleaned fluid caused by the filter piston in the pump chamber and thus in the pump chamber an overpressure is built up, which in a third cycle with solids leaking concentrated fluid through the concentrate outlet valve.
- the piston pump semi-continuous self-cleaning.
- the end-controlled exhaust valve closing with a Exhaust valve spring biased over a drawbar which makes it structurally simple can be produced.
- a negative pressure is formed, which the fluidized fluid 9 over the thus opened Inlet valve 3 can flow into the pump chamber 4.
- Fig. 2 decreases in the movement of the pump space 4 and the space with solids offset fluid 9 is compressed, whereby the upstream filter piston 7 against the Bias of the axially biasing filter springs 6 is moved to the piston 5 and the outlet valve 8 opens, which filtered through the filter piston 7 and through the Piston 5 compressed purified fluid 9 can flow out.
- the pump chamber 4 collects the solids-concentrated fluid 9.
- the piston pump 1 is an automatically closing Konzentratauslassventil 10 to the pump chamber 4, which at an overpressure in Pumping space 4, the solids-concentrated fluid 9 leaves.
- the self-employed closing exhaust valve 8 is end-controlled closing with a Auslassventilfeder 11 biased over a pull rod 12, which at a short before the bottom dead center of the movement Her arranged axial stop 13 of the filter piston 7 the Exhaust valve 8 closes and thus a return flow of the purified fluid 9 through the Filter piston 7 forces into the pump chamber 4, whereby in the pump chamber 4, an overpressure is constructed, which the solids-concentrated fluid 9 on the Concentrate outlet valve 10 leaves.

Description
Claims (8)
- Kolbenpumpe mit einem Zylinder (2), einem selbstständig schliessendem Einlassventil (3) zu einem Pumpraum (4), einem dichtend hin- und herbewegbaren Kolben (5) und einem dichtend vorgelagerten Filterkolben (7), dadurch gekennzeichnet, dass der Kolben (5) mit dem vorgelagerten Filterkolben (7) federnd vorgespannt, axial begrenzt beweglich ist, und dass der Kolben (5) mit dem Filterkolben (7) ein selbstständig schliessendes Auslassventil (8) ausbildet.
- Kolbenpumpe nach Anspruch 1, dadurch gekennzeichnet, dass sie ein selbstständig schliessendes Konzentratauslassventil (10) zum Pumpraum (4) aufweist.
- Kolbenpumpe nach Anspruch 2, dadurch gekennzeichnet, dass kurz vor dem unteren Totpunkt des Filterkolben (7) ein Axialanschlag (13) ausgebildet ist und dass das selbstständig schliessende Auslassventil (8) zusätzlich endseitig weggesteuert schliessend ausgeführt ist, wodurch eine Rückströmung des gereinigten Fluids (9) durch den Filterkolben (7) und ein das Konzentratauslassventil (10) öffnender Überdruck erzeugbar ist.
- Kolbenpumpe nach Anspruch 3, dadurch gekennzeichnet, dass das endseitig weggesteuert schliessende Auslassventil (8) mit einer Auslassventilfeder (11) über einer Zugstange (12) vorgespannt ist.
- Kolbenpumpe nach einem der vorherigen Ansprüche, dadurch gekennzeichnet, dass der Kolben (5) mit dem vorgelagerten Filterkolben (7) über zumindest eine axial vorspannende Filterfeder (6) miteinander verbunden sind.
- Verfahren zur Förderung und Filterung eines mit Feststoffen versetzten Fluids wobei eine Kolbenpumpe nach einem der vorhergehenden Ansprüche verwendet wird, wobei in einem ersten Arbeitstakt der Kolben (5) durch seine axiale Hin-Bewegung den Pumpraum (4) vergrössert, wodurch bei geschlossenen Auslassventil (8) ein Unterdruck entsteht, welcher das mit Feststoffen versetzte Fluid (9) über das dadurch geöffnete Einlassventil (3) in den Pumpraum (4) einströmen lässt, und wobei in einem zweiten Arbeitstakt sich durch seine axiale Her-Bewegung der Pumpraum (4) verkleinert und das mit Feststoffen versetzte Fluid (9) verdichtet wird, wodurch der vorgelagerte Filterkolben (7) gegen die Vorspannung auf den Kolben (5) zubewegt wird und das Auslassventil (8) öffnet, welches das durch den Filterkolben (7) gefilterte und durch den Kolben (5) verdichtete gereinigte Fluid (9) ausströmen lässt.
- Verfahren nach Anspruch 6, dadurch gekennzeichnet, dass in einem dritten Takt das mit Feststoffen aufkonzentrierte Fluid (9) über das Konzentratauslassventil (10) ausgelassen wird.
- Verfahren nach Anspruch 7, dadurch gekennzeichnet, dass in dem dritten Takt eine Rückströmung des gereinigten Fluids (9) durch den Filterkolben (7) in den Pumpraum (4) bewirkt wirkt.
