Descriptio Brevis:

Conspectus et principium obsignationisf Anulus O-electricus

Ad quid est anulus O e gummi et quale gummi in anulis O adhibetur? Anulus O, etiam anulus O appellatus, est genus anuli e gummi cum forma sectionis transversalis circularis. Anulus O est elementum obturans latissime adhibitum in systematibus hydraulicis et pneumaticis. Anulus O bonam vim obturantem habet, quae ad obturationem tam staticam quam dynamicam adhiberi potest; non solum solus adhiberi potest, sed etiam pars fundamentalis multorum instrumentorum obturantium compositorum est. Amplam applicationum varietatem habet, et si materiae recte seleguntur, requisitis variorum mediorum et condicionum motus satisfacere potest. Anulus obturans formae O est obturamentum extrusionis, et principium operationis basicum obturamenti extrusionis est niti deformationi elasticae elementi obturantis ad pressionem contactus in superficie contactus obturantis creandam. Si pressio contactus maior est quam pressio interna medii obturati, nulla effusio fiet, aliter effusio fiet.

Secunda - Frequentia compressionis et quantitas extensionis proanuli toriformis

Anulus O est typicum obturamentum extrusum. Ratio compressionis et magnitudo extensionis diametri sectionis transversalis anuli O sunt elementa principalia designationis obturamenti, quae magni momenti sunt ad effectum obturamenti et diuturnitatem utilem. Bonus effectus obturamenti anuli O maxime pendet ex recta congruentia magnitudinis anuli O et magnitudinis sulci, efficiendo quantitatem compressionis et extensionis rationabilem anuli obturantis.

1. Frequentia compressionis

Ratio compressionis W vulgo sic exprimitur:

W = (d₀ h)/d₀× 100%

In formula, d0 - diameter sectionis transversalis anuli O in statu libero (mm);

H - Spatium inter fundum sulci O-anuli et superficiem obsignatam (profunditas sulci), id est altitudo sectionis transversalis O-anuli post compressionem (mm)

2. Cum proportio compressionis anuli O eligitur, haec tria consideranda sunt:

(1)Satis areae contactus obturantis esse debet;(2)Conare vim frictionis ad minimum redigere;(3)Deformationem permanentem vitare conare.

Ex his factoribus non difficile est videre inter se contradictiones inter se esse. Alta compressio pressionem contactus magnam consequi potest, sed nimia compressio frictionem labens et deformationem permanentem sine dubio auget. Si compressio nimis parva est, hoc fieri potest propter errorem coaxialitatis et errorem anuli O sulci obturantis qui requisitis non satisfaciunt, quod efficit ut aliqua compressio evanescat et effluxio fiat. Ergo, cum ratio compressionis anuli O eligitur, necesse est varias res ponderare. Generaliter, compressio obturantium staticorum maior est quam obturantium dynamicorum, sed eius valor extremus minor quam 25% esse debet. Alioquin, vis compressionis significanter relaxabitur et nimia deformatio permanens fiet, praesertim in condicionibus laboris altae temperaturae.Delectus rationis compressionis W pro obturatoribus anulorum O-ringorum condiciones usus, ut obturamenta statica an dynamica, considerare debet; obturatio statica in obturationem radialem et obturationem axialem dividi potest; rima radialem obturatorum radialium (vel obturatorum staticorum cylindricorum) est, dum rima axialem obturatorum axialium (vel obturatorum staticorum planorum) est. Obturatio axialis in duas condiciones dividitur secundum utrum medium pressionis in diametrum internum an in diametrum externum anuli O-ringi agat: pressio interna et pressio externa. Incrementum pressionis internae ad extensionem ducit, dum pressio externa extensionem initialem anuli O-ringi minuit. Formae diversae obturatorum staticorum supra memoratae diversas directiones actionis medii obturantis in anulum O-ringum habent, ergo designatio prae-pressionis etiam differt. Pro obturatoribus dynamicis, necesse est distinguere inter obturamenta motus reciprocantis et obturamenta motus rotatorii.

(2)Obsignatio statica: Similiter ac machinae obsignationis reciprocae, machinae obsignationis staticae cylindricae plerumque W=10% ad 15% requirunt; machina obsignationis staticae planae W=15%~30% requirunt.Ad obsignationem dynamicam, in tres condiciones dividi potest; motus reciprocus plerumque ut W = 10% ad 15% accipitur. Cum proportio compressionis pro obsignationibus motus rotatorii eligitur, effectus caloris Joule considerandus est. Generaliter loquendo, diameter interior anuli O ad motum rotatorium adhibiti 3% -5% maior est quam diametrus axis, et proportio compressionis diametri exterioris est W = 3% -8%. Pro ludis frictionis humilis, anuli O plerumque cum minore proportione compressionis W = 5% -8% eliguntur ut resistentia frictionis minuatur. Praeterea, expansio materiarum gummi a medio et temperatura effecta etiam consideranda est. Solet, ultra deformationem compressionis datam, maxima ratio expansionis permissa est 15%. Excessus huius ambitus indicat selectionem materiae non aptam esse, et anulos O aliarum materiarum loco eorum adhibendos esse, vel datam rationem deformationis compressionis corrigendam esse.

(3)Quantitas extensionis,Postquam in sulco obturatorio inseritur, anulus toricus (O-ring) plerumque certum gradum extensionis subit. Sicut celeritas compressionis, ita etiam magnitudo extensionis magnum momentum habet in effectu obturatorio et vita utili anuli torici. Magna extensio non solum difficilem reddit installationem anuli torici, sed etiam gradum compressionis minuit propter mutationes in diametro sectionis transversalis d0, quod ad effusionem ducit. Magnitudo extensionis a sic exprimi potest:α= (d+d₀)/(d₁+d₀)In formula, d est diameter axis (mm); D1 est diameter interior anuli toriformis (mm).Amplitudo quantitatis extensionis est 1% -5%. Valores commendati pro quantitate extensionis anuli O in tabula dantur. Quantitas extensionis anuli O secundum magnitudinem diametri axis secundum limitem selectionis tabulae eligi potest. Amplitudo praecedentiae rationis compressionis et quantitatis extensionis pro anulo O.

Tertio - relatio inter diametrum internum (ID), diametrum externum (OD), et diametrum fili (C/S) anuli O-ringi.

OD = ID + C/S * 2 Exempli gratia: ID = 3 MM C/S = 1 MM OD = 3 MM + 1 * 2 = 5 MM

Quintae - specificationes anulorum toricorum e gummi. Methodi et instrumenta mensurae.

Instrumenta mensurae communia habere:

1-Proiector altae praecisionis

Proprietates instrumenti:Mensura sine contactu, mensuram invisibilem reddens et aptam ad partes tenues et molles metiendas; functionem amplificationis imaginis validam et facultatem mensurae magnitudinis parvae fortiorem habet; celeritas mensurae efficacitatem mensurae magnopere auget; densitas punctorum exemplificationis magnam fidelitatem mensurae praestat; commoda prehensio.

2-Caliperum electronicum digitale

Proprietates instrumenti:Instrumentum ad mensuram longitudinis quod systemata mensurae, ut retia capacitiva et magnetica, adhibet ad valores mensurae digitaliter exhibendos. Resolutio vulgo adhibita est 0.01mm, cum errore admissibili ± 0.03mm/150mm. Sunt etiam circinatores digitales altae praecisionis cum resolutione 0.005mm, cum errore admissibili ± 0.015mm/150mm. Est etiam circinator micrometricus digitalis multi-usus cum resolutione 0.001mm (quod est patentum nationale pro instrumentis mensurae Anyi et solum illi eum producere possunt), cum errore admissibili ± 0.005mm/50mm. Propter lectionem intuitivam et claram, efficientia mensurae alta est.

3-Regula π(PITAPE)

Proprietates instrumenti:

1. Regula π ex lamina elastica chalybea constat. In duobus extremis eius regula principali et auxiliari respective insculpta sunt. Minimum graduum graduum regulae principalis est 0.5mm vel 1mm; minimi graduum graduum regulae auxiliaris sunt 0.02mm, 0.05mm, 0.01mm, 0.1mm, et cetera.

2. Cum in usu est, regulam π circum rem lavorandam volve et methodo legendi vernieri utere ad diametrum medium partis mensuratae directe legendum.

Commoda et incommoda

(1). Alta accuratio: Cum diameter per circumferentiam regulae π metiatur, error designationis in productione regulae vicibus π reduci potest et in resultatibus mensurae reflecti. Ergo in φ In mensuris magni diametri supra 500mm, eius accuratio maior est quam ea coemeteris vernieri. Hoc commodum praesertim eminet in mensuris supra 1000mm.

(2). Cum partes ferreas regula π metiuntur, temperatura partis operis non afficitur. Hoc fit quia regula π tenuissima est, et brevissimo tempore per mensurationem aliter se habebit cum parte probata. Praeterea, coefficientes expansionis thermalis earum valde propinqui sunt, vim temperaturae fere superantes.

(3. In mensura diametrorum magnorum et extra magnorum, usus partium auxiliarium (pontium magneticorum patentatorum) facilem operationem ab uno homine simul permittit.)

(4). Mensura partium tenuium non facile deformationem operis efficit. (5). Facile portatur et reponitur. (6). Pretium humile est.

(7). Incommodum: Lectionem claudere non potest; Deviationes geometricae, ut ovalitas, metiri non possunt.

Sextus usus anuli torici et installatio anuli torici.

1. Usus anuli torici

Anulus toricus (O-ring) late adhibetur in iuncturis variarum partium hydraulicarum et pneumaticarum, superficiebus cylindrorum, et superficiebus flangarum. Pro anulis toricis in motu adhibitis, cum pressio operandi maior est quam 9.8Mpa et pressioni unidirectionali subiecta est, anulus retinens in altera parte anuli torici in directionem pressionis collocandus est; si compressionem bidirectionalem subiectam est, anulus retinens in utraque parte anuli torici collocandus est. Ad frictionem minuendam, anuli retinentes cuneiformes etiam adhiberi possunt. Cum liquor pressio a sinistra applicatur, anulus retinens dexter sursum impellitur, et anulus retinens sinister superficiem obsignatam non tangit, ita vim frictionis minuens. In universum, usus anulorum retinentium vim frictionis instrumenti obsignationis auget, et anuli retinentes cuneiformes magnae momenti sunt in hac vi frictionis minuenda. Pro anulis toricis fixis, anulus retinens etiam requiritur cum pressio operandi maior est quam 32Mpa.

2. Oring installatio

Qualitas institutionis anulorum O-ringorum magnum momentum habet in eorum efficacia obsignationis et vita utili. Problemata effusionis saepe ex institutione mala oriuntur. Dum instituuntur, non licet anulum O-ringum scalpi, male alignari, aut torqueri. Ante compositionem, sulcus obsignationis et superficies obsignationis congruens diligenter purgandae sunt; simul, adipem lubricans superficiei, quae per eam transire debet dum instituitur, applica. Ne anulus O-ringorum a marginibus acutis, ut angulis acutis et filis, durante institutione secetur aut scalpitur, angulus introductionis 15° ad 30° in extremo axis et extremo foraminis institutionis relinquendus est. Cum anulus O-ringorum per filum externum transire debet, manica ductoria metallica specialis tenuis parietibus ad filum externum tegendum adhibenda est; si anulus O-ringorum per orificium transire debet, orificium in formam diagonalem correspondentem invertendum est ne anulus O-ringus scalpatur. Angulus inclinationis sulci plerumque est a=120°~140°.
