BeskrivelseDescription

BenævnelseDenominations

Serieforbundet hoved- og forpumpe.Series connected main and front pump.

Frembringelsens anvendelsesområdeScope of production

Denne frembringelse angår en pumpestation med hovedpumpe og forpumpe sammenbygget i en serie.This generation relates to a pump station with a main pump and a pre-pump built into a series.

Pumpen anvendes i forbindelse med transport og udbringning af svært flydende væske så som gylle.The pump is used in connection with the transport and delivery of very liquid liquids such as manure.

Pumpen kan også anvendes til let flydende væsker som vand. Pumpestationen er af den type, der består af en hovedpumpe, der giver tryk og kapacitet.The pump can also be used for lightly flowing liquids such as water. The pump station is of the type consisting of a main pump which provides pressure and capacity.

I serie med denne er der for enden af sugeslangen en neddyppet forpumpe, der spæder hovedpumpe, giver kapacitet og forhindrer o verri vrang af vandsøjle.In series with this, there is at the end of the suction hose a submerged front pump that dilutes the main pump, provides capacity and prevents the erosion of the water column.

Ved gasholdige væsker så som gylle nedsættes muligheden for forstyrrelse af pumpningen p.g.a. frigivelse af gas.For gaseous liquids such as manure, the possibility of interfering with the pumping is reduced due to gas release.

Kendt teknik I kendte pumpesystemer er der flere opbygningsformer: 1. SlamsugerenPrior Art In known pump systems there are several types of construction: 1. The sludge cleaner

Pumpning finder sted ved at frembringe vakuum i tank, ved efterfølgende tømning, opbygger pumpen lufttryk i tanken.Pumping takes place by generating vacuum in the tank, upon subsequent emptying, the pump builds up air pressure in the tank.

2. Selvansugende pumpe2. Self-priming pump

Pumpe suger væske gennem slanger fra lagertank.Pump sucks fluid through hoses from storage tank.

3. Pumpe for ende af sugeslange3. Pump for end of suction hose

Pumpen er med sugeslangen neddyppet i lagertank og fylder væsken direkte til anden tank.With the suction hose, the pump is immersed in the storage tank and fills the liquid directly to the second tank.

De kendte problemer der skal løsesThe known problems to be solved

De kendte opbygninger er uhensigtsmæssige, når der ønskes meget store kapaciteter samtidig med minimal skumdannelse. De bliver dyrere, fordi alle komponenter skal overdimensioneres. Pumpesystemet skal køre med effektforbrug som svarer til standard traktorer ved landbruget.The known structures are inconvenient when very large capacities are desired at the same time as minimal foaming. They become more expensive because all components must be oversized. The pump system must run with power consumption that corresponds to standard agricultural tractors.

D_en nye teknik.The new technique.

Det nye ved frembringelsen udgøres af, at pumpesystemet består af en sammenbygning af en kendt standard pumpe i serie med en dygpumpe i en speciel udformning.What is new in the production is that the pumping system consists of a combination of a known standard pump in series with a dew pump in a special design.

Den nye udformning af dykpumpen muliggør en hensigtsmæssig opbygning i et cylindrisk hus, der er brugervenlig. Opbygningen muliggør stor væskegennemgang i forhold til dykpumpens kapacitet (kraftforbrug).The new design of the submersible pump allows for a convenient construction in a user-friendly cylindrical housing. The structure allows for a large flow of fluid in relation to the capacity of the submersible pump (power consumption).

Frembringelsen og en fordelagtig udførelses for forklares i det følgende.The production and an advantageous embodiment for are explained below.

Udførelses eksempelerExamples of execution

Fig. 1 Viser en standard hovedpumpe, som også fungerer som spredepumpe ved tankvogne. Pumpen laver tryk og kapacitet ved optagelse af hovedparten af pumpeeffekten, illustreret ved 80% af total effekt.FIG. 1 Displays a standard main pump, which also serves as a spreading pump for tankers. The pump creates pressure and capacity when recording most of the pump power, illustrated at 80% of total power.

Fig. 2 Viser cylindrisk forpumpe.FIG. 2 Displays cylindrical front pump.

Cylindrisk pumpehus (T) er monteret på sugeslangen (2) . I pumpehus (T) er monteret motor (3) med rotor (4)Cylindrical pump housing (T) is mounted on suction hose (2). In pump housing (T) is mounted motor (3) with rotor (4)

Indsugningsåbning (J) har en indløbstragt (6) Forpumpen bruger en lille del af total effekten illustreret med 20%.Inlet opening (J) has an inlet funnel (6) The front pump uses a small part of the total power illustrated by 20%.

Efter behov kan pumpestationen opbygges så forholdene mellem effekterne ved hoved og forpumpe fordeles efter behov.As needed, the pump station can be built up so that the ratios of the main and front pump effects are distributed as needed.
