Description

469 189 Pumpöverdelen 2 innefattar en drivmekanism 5, som kan bestå av en manuellt påverkbar dragvev 6, en drivmotor etc, som via en växel 7, exempelvis en kuggväxel eller snäckväxel, är sammankopplad med en drivaxel 8, som via en drivförbindning 9 är förbindbar med en i pumpnederdelen 3 mottagbar på avstånd från drivmekanismen 5 belägen pump 10. 469 189 The pump upper part 2 comprises a drive mechanism 5, which may consist of a manually actuable traction web 6, a drive motor etc, which via a gear 7, for example a gear or worm gear, is connected to a drive shaft 8, which is via a drive connection 9 connectable to one remote in the pump lower part 3 from drive pump 5 located on the drive mechanism 5.

Pumpöverdelen 2 kan bestå av ett hus ll, vilket är sammanbyggt av ett antal med skruv 12 kopplingsbara husdelar 11A, 11B, och som kan anslutas till ett exempelvis av betong bestående fundament 13, som vilar på marken 14 och som är fäst med lämpliga fästelement 15.The pump upper part 2 can consist of a housing ll, which is assembled from a number of 12 connectable housing parts with screws 11A, 11B, and which can be connected to an example of concrete permanent foundation 13, which rests on the ground 14 and which is attached with suitable fasteners 15.

Ett utloppsrör 16, som ansluter till ett från det i marken 14 åstadkomna borrhålet 4 eller annat pumpuppforslings- utrymme, i vilket kan mottagas ett av plastmaterial bestående, format rör 17, en slang eller något liknande element, mynnar från husets inre utrymme 18 till dess utsida och genom vilket vatten eller annat pumpbart fluidum, som avses pumpas medelst pumpen 10 kan utströmma. Röret 16 kan via en tätfläns 19 tätas mot huset 11 mellan dess inre och yttre.An outlet pipe 16, which connects to one from it in the ground 14 borehole 4 or other pump supply space in which a plastic material can be received, shaped pipe 17, a hose or similar element, opens from the interior space 18 of the housing to its exterior and through which water or other pumpable fluid, which is intended to be pumped by the pump 10 can flow out. The pipe 16 can be sealed via a sealing flange 19 against the housing 11 between its interior and exterior.

Pumpen 10, som är av det slaget att den inne- fattar en i en stators 20 inre hålrum 21 mottagbar roterbar rotor 22, företrädesvis en s k monoskruvpump, är via sagda drivförbindning 9 anordnad att drivas så att rotationsrörelse överföres från drivmekanismen 5 till pumpens sagda rotor 22 för att uppforsla pumpbart fluidum i hålrummet 21 allteftersom rotorn roteras i avsedd pumprotationsriktning. Statorn 20 kan vara fästad till en med plaströret 17 förbunden rördel 23, som vid dess nederdel uppvisar kopplingorgan 24, exempelvis gängor för sammankoppling med ett ventilhus 25, i vilket mottages en ventilkropp 26, som är pâverkbar av en fjäder 27 för att möjlig- göra horisontellt montage. Rotorn 22 är medelst övre och/eller nedre stopporgan 28, 29, exempelvis stoppbultar, spärrade till statorn för att förhindra att rotorn 22 förs ut ur statorn 20.The pump 10, which is of the type that it contains takes a rotatable member receivable in the inner cavity 21 of a stator 20 rotor 22, preferably a so-called mono-screw pump, is via said drive connection 9 arranged to be driven so that rotational movement transmitted from the drive mechanism 5 to the said rotor 22 of the pump for to supply pumpable fluid into the cavity 21 as appropriate the rotor is rotated in the intended direction of pump rotation. The stator 20 can be attached to a pipe part 23 connected to the plastic pipe 17, which at its lower part have coupling means 24, for example threads for connection to a valve housing 25, in which a valve body 26, which is actuated by a spring 27 to enable make horizontal mounting. The rotor 22 is by means of the upper and / or lower stop means 28, 29, for example stop bolts, locked to the stator to prevent the rotor 22 from being ejected from the stator 20.

Enligt föreliggande uppfinning utgöres drivför- bindningen 9 av en lina eller av något liknande organ, som är böjligt för att kunna sammanpackas till liten volym. Företrädes- vis utgöres drivförbindningen av en vajer av metallmaterial närmare bestämt av en plastöverdragen dubbelslagen stålvajer.According to the present invention, the drive the bond 9 of a rope or of a similar member, which is flexible to be able to be packed into small volumes. Preferred In this way, the drive connection consists of a wire made of metal material more precisely by a plastic-coated double-stranded steel wire.

Sagda lina etc 9 måste emellertid vara av det slaget att den är x a? 469 189 så vridstyv att den möjliggör att överföra vridrörelse från dess ena till dess andra ände 9A resp 9B, samt uppvisa sådan längd- utsträckning att den överensstämmer med den verksamma sträckan hos ett ifrågavarande pumpuppforslingsutrymme 4, så att linan 9 hålles i väsentligt utsträckt läge under pumpningsförloppet.Said line etc 9 must, however, be of the kind that it is x a? 469 189 so torsionally rigid that it makes it possible to transmit rotational motion from it one to its other end 9A and 9B, respectively, and exhibit such longitudinal to the extent that it corresponds to the operating distance of a pump storage space 4 in question, so that the line 9 kept in a substantially extended position during the pumping process.

Linan etc 9 är anordnad att förbindas med driv- axeln 8 med dess ena ände 9A och med pumprotorns övre fria ände 22A vid dess andra ände 9B, Därvid kan sagda linändar 9A, 9B vara formade till förbindningar, exempelvis slingor, som visas på ritningarna och vilka är sammankopplade med linan 9 medelst klämmor 30, 31, som kan mottagas av till resp del ansluten vridöverföringsdel 32, 33. Även plaströret etc 17, som mottages i borrhålet 4 och huset ll kan vara fäst medelst klämmor 34, 35 till ut- loppsröret 16 resp till pumprördelen 23.The line etc. 9 is arranged to be connected to the drive shaft 8 with its one end 9A and with the upper free end of the pump rotor 22A at its other end 9B, said line ends 9A, 9B be formed into connections, for example loops, which are shown in the drawings and which are connected to the line 9 by means of terminals 30, 31, which can be received by the respective parts connected rotary transmission part 32, 33. Also the plastic pipe etc 17, which is received in the borehole 4 and the housing 11 may be fixed by means of clamps 34, 35 to the outlet the flue pipe 16 or to the pump pipe part 23.

Funktionen av den ovan beskrivna och pà rit- ningarna visade uppfinningen torde klart ha framgått av det ovan sagda. Kortfattat kan dock sägas att när drivaxeln 8 påverkas att roteras i önskad pumpriktning överföres drivrörelsen till linan 9. Linan 9 överför därefter i sin tur den roterande rörelsen från dess övre ände 9A till dess nedre ände 9B, för att slutligen överföras till pumprotorn 22, så att denna kan drivas och uppforsla avsett pumpbart pumpfluidum, exempelvis vatten.The function of the above-described and The invention showed would clearly have been apparent from the foregoing sagda. Briefly, however, it can be said that when the drive shaft 8 is affected to be rotated in the desired pump direction, the drive motion is transmitted to line 9. Line 9 then in turn transmits the rotary the movement from its upper end 9A to its lower end 9B, to finally transferred to the pump rotor 22 so that it can be driven and supplying intended pumpable pump fluid, for example water.

Allteftersom linan 9 påverkas att roteras, fortsätter fluidumet att uppforslas ur borrhålet, brunnen, tanken etc 4 och kan uttagas vid utloppsröret 16.As the line 9 is caused to rotate, the fluid continues to be retrieved from the borehole, well, tank, etc. 4 and can removed at the outlet pipe 16.

Linan etc 9 kan lätt bytas vid behov liksom att pumpen 10 lätt kan transporteras mellan borrhålets nedre resp övre ände genom att man enkelt hissar pumpen 10 med den böjliga linan 9.The rope etc 9 can be easily changed if needed as well as that the pump 10 can be easily transported between the lower resp upper end by simply hoisting the pump 10 with the flexible one line 9.

Uppfinningen är ej begränsad till det ovan beskrivna och på ritningarna visade utföringsexemplet av en pumpanordning utan kan varieras inom ramen för patentkraven utan att uppfinningstanken frångås.The invention is not limited to the above described and shown in the drawings the embodiment of a pump device without can be varied within the scope of the claims without that the inventive idea is abandoned.
