Description
Vynález sa týká membránového kapacitného rýchlomera toku kvapalín.The invention relates to a membrane capacitive liquid flow rate meter.
Doteraz používané metody meranie rýchlosti toku kvapalín aú založené najma na principech vrtulkových rýchlomerov, napr. Voltmanovho křidélka. Nevýhodou vrtulkových rýchlomerov je, že sa rotačně uložená vrtulka v třecích ložiskách často zadiera najma pri znečistění ložiska a okrem toho je výroba vrtulky poměrně složitá a drahá.The methods used to measure the flow rate of liquids hitherto are based in particular on the principles of propeller speedometers, e.g. Voltman's wings. The disadvantage of the propeller speedometers is that the rotary-mounted propeller in the friction bearings often seizes especially when the bearing is contaminated and, in addition, the manufacture of the propeller is relatively complex and expensive.
Uvedené nedostatky odstraňuje membránový kapacitný rychloměr toku kvapalín, v ktorom je v membránovom talese upevněná polymérová membrána stlačená predpitou pružinou, opretá o pružinové sedlo podTa vynálezu, ktorého podstata spočívá v tom, že na profilovanej polymérovej membráně je nalepená pohyblivá doska kondensátora a pevná doska kondensátora upevněná v izolačnom krúžku s vývodmi a na rúrke zalisovanej v membránovom teleae je nasunutá hadica s tesniacim závitovým krúžkom a ňalgim tesniacim krúžkom.The above mentioned drawbacks are eliminated by the membrane capacitive speedometer in which the polymer membrane is fixed in the membrane plate by compressed by a spring biased against the spring seat according to the invention, which consists in that a movable capacitor plate and a fixed capacitor plate are attached to the profiled polymer membrane. in the insulating ring with outlets and on the tube molded in the membrane body, a hose with a threaded sealing ring and a non-sealing sealing ring is inserted.
Vynélez membránového kapacitného rýchlomera toku kvapalín umožňuje rýchlo merať okamžitá rýchlosť toku vody a ostatných kvapalín a diaTkový přenos Údajov, přitom namerané hodnoty možno indikovat na čislicovej stupnici.The invention of a membrane capacitive liquid flow rate meter enables rapid measurement of the instantaneous flow rate of water and other fluids and remote data transmission, while the measured values can be indicated on a digital scale.
Membránový kapacitný rýchlomer toku kvapalín je v řeze znázorněný na pripojenom . výkrese.The diaphragm capacitive liquid flow rate meter is shown in section on the attached. drawing.
V telese J. je upevněné profilovaná polymérová membrána £, ktoré má na právej straně nalepenú pohyblivá došku 2 kondensátora. Silové dčinky tečúcej kvapaliny zachytává predpatá pružina 1 opretá o nastaviteTné pružinové sedlo í so závitom. Profilovaná polymérová membrána 2 j® upevněná v sedle telesa J. v izolačnom krúžku £, v ktorom je umiestnená aj pevná doska 1 kondensátora s vývodom 2·A profiled polymer membrane 6 is mounted in the body 1 and has a movable capacitor thatch 2 glued on the right side. The biasing force of the flowing fluid is absorbed by the biasing spring 1 supported by an adjustable threaded spring seat. The profiled polymer membrane 2 is fastened in the seat of the body 1 in the insulating ring 6, in which a fixed capacitor plate 1 with an outlet 2 is also located.
Na rúrke 12 zalisovanej v telese 1 je nasunutá hadica 13 s tesniacim závitovým krúžkom 14 a tesniacim krúžkom 15. Pružinové sedlo 2 30 závitom sa zaistí po kalibrácii rýchlomera skrutkou 12* Při meraní rýchlosti toku kvapalín je Tavé strana profilovanej polymerovej membrány 2 v priamom styku 8 prúdiacim médiom a směr prúdnic je rovnoběžný s osou symetrie polymárovej membrány 2.On the tube 12 molded in the body 1, a hose 13 with a threaded ring 14 and a ring 15 is inserted. The spring seat 2 30 is threaded by a screw 12 after calibration of the speedometer. * When measuring the flow rate of liquids, and the direction of the nozzles is parallel to the symmetry axis of the polymer membrane 2.
V důsledku odklonu prúdnic na profilovanej polymárovej membráně 2 sa vytvoří sila P, Ktorá pfisobí na polymérovú membránu 2 podTa vztahu P = Gs/g.c.sin alfa, kde Gg je sekundové množstvo prietoku kvapaliny, ktoré je profilovanou polymérovou membránou 2 vychýlené z pfivodného směru toku, g je gravitačné zrýehlenie, c je rýchlosť toku kvapaliny a alfa je uhol odklonu prúdnic od pfivodného směru.As a result of the deflection of the nozzles on the profiled polymer membrane 2, a force P is generated which applies to the polymer membrane 2 according to the relation P = G s / gcsin alpha, where G g is the second amount of liquid flow. , g is gravity ironing, c is the flow rate of the liquid and alpha is the angle of deflection of the nozzles from the inlet direction.
Pre meranú rýchlosť toku kvapaliny potom platí c = P.g/Gg.sin alfa. Přitom třeba rýchlomer kalibrovat v ciachováných hydro-kanáloch. Sila P je v rovnováhe s tuhostou systému polymérovej membrány 2 pjj * pružiny i Pz, pretože platí, že P = P^j + P%. V dfisled· ku pfisobenia dynamického tlaku vznikne v mieste 17 elastická daformácia profilovanej polymérovej membrány 2 A v, ktorá sa pre jeví v zmene kapacity vytvorenej dvojicou dosák 2 a 2 kondenzátora.For the measured liquid flow rate, then c = Pg / G g .sin alpha. The speedometer must be calibrated in calibrated hydraulic channels. The force P is balanced with the rigidity of the polymer membrane 2 JJ * p P of the spring, as it is true that P ^ = P j + P%. As a result of the dynamic pressure, an elastic deformation of the profiled polymer membrane 2A v occurs at 17, which appears to change in the capacity created by the pair of capacitor plates 2 and 2.
Tieto změny kapacity A c sú úměrné změnám deformácie profilovanej polymérovej membrány 2, t. j. A c 3® úměrné A y· Změny barometrického tlaku počas merania neovplyvňujú merané výsledky, pretože na pravú aj 1’avú stranu profilovanej polymérovej membrány 2 pfisobí stále rovnaký barometrický tlak pomocou hadice 12, ktorá je spojená s atmosférou. Rozsah rýchlomera sa nastavuje predpatím pružiny 2·These changes in capacity A c are proportional to the deformation changes of the profiled polymer membrane 2, ie A c 3® proportional to A y. a hose 12 which is connected to the atmosphere. The speedometer range is adjusted by spring bias 2 ·
Membránový kapacitný rýchlomer toku kvapalín možno využit na meranie rýchlosti toku kvapalných médií tak v otvorených ako aj uzavretýeh kanáloch a potrubiach.The membrane capacitive liquid flow rate meter can be used to measure the flow rate of liquid media in both open and closed channels and pipelines.
