Umvavanyi woxinzelelo lwe-asidi ye-acid usetyenziswa ikakhulu ukuvavanya ukuxhathisa kuxinzelelo lwe-static (uxinzelelo lwe-asidi ye-static) ye-asidi yelaphu kunye nesiseko sempahla ekhuselayo yemichiza. Sisixhobo sokuvavanya i-asidi kunye nesiseko sempahla yeekhemikhali zokukhusela i-asidi kunye nesiseko samashishini okuvelisa imichiza kwilayisenisi yokuvelisa kunye ne-LA (Lao-an) isatifikethi, iiyunithi zokulawula kunye nokuvavanya kunye namaziko ophando lwesayensi. Hlangana nomgangatho: GB24540-2009;
Iimpawu zovavanyo loxinzelelo lwe-asidi engatshintshiyo:
I-1, ukusetyenziswa kwebhokisi yokulawula umbane kunye nemodi yokuhlukanisa ibhokisi yovavanyo, ugweme uhlobo lwebhokisi lovavanyo lwe-asidi yokuvuza imingcipheko yokhuseleko lwesekethe.
I-2, igumbi lokuvavanya lenziwe ngezinto zensimbi ezingenasici, ezinciphisa amathuba okuba ne-asidi yebhokisi, ukuze ibhokisi ikwazi ukugcina isibuko sigudile ixesha elide.
I-3, umbhobho wokuvavanya izixhobo, umlomo wenaliti yolwelo kunye nekliphu yesampulu esebenzisa ukugqwala kwe-polytetrafluoroethylene enganyangekiyo, xa kuthelekiswa nemathiriyeli yentsimbi, iphucula kakhulu ukuxhathisa ukubola kunye nobomi benkonzo.
4, umbhobho wokuvavanya usebenzisa umbhobho we-ptfe ocacileyo, ukuqinisekisa ukuba akukho amaqamza xa udibanisa ulwelo, ukuhamba kolwelo okugudileyo ngakumbi, ukuphucula ukuchaneka kunye nexesha elifanelekileyo lovavanyo.
I-5, i-DRK711 i-static acid tester pressure tester ithatha isakhiwo soyilo esisodwa, siphucule ukuchaneka kwezixhobo, ukusuka ekuchanekeni kokuqala kwe-3mm ukuya kwi-1mm.
I-6, umphambili wezixhobo zokwandisa isikali, nokuba abasebenzi bokulinga nangaliphi na ixesha ukuqinisekisa ukuchaneka kweziphumo zovavanyo, kunye nokulinganisa izixhobo ezifanelekileyo.
I-7, umlomo wenaliti yolwelo kunye nekliphu yesampulu ecacileyo ebonakalayo, ukuphucula ukhuseleko lwe-asidi kunye novavanyo lwealkali.
I-8.Umnini wesampuli wamkela isakhiwo esikhethekileyo ukuqinisekisa ukuba isampuli ikwimeko eqinile; I-specimen clamping plate ithatha isakhiwo esijikelezayo esisecaleni, esikhuselekileyo nesilungele ukusebenza, kwaye siphucula ukusebenza kovavanyo kunye nokuchaneka kweziphumo zovavanyo.
Umvavanyi we-coefficient ye-coefficient yesikrini sokuchukumisa
Umvavanyi we-coefficient yesikrini sokucofa ulungele ukulinganisa i-coefficient yefriction kunye ne-dynamic friction coefficient yefilimu yeplastiki kunye necandelo elincinci, irabha, iphepha, ikhadibhodi, isitayile selaphu kunye nezinye izinto xa utyibilika. Sisixhobo sokuvavanya iimpawu zokukhuhlana kwezinto. Sisixhobo sokuvavanya esiyimfuneko kubavelisi bezinto eziphathekayo kunye namasebe okuhlola umgangatho. Ikwasisixhobo sovavanyo esiyimfuneko kumaziko ophando lwenzululwazi ukufunda imathiriyeli emitsha. Inkqubo edibeneyo ye-ARM, isikrini esikhulu sokulawula umbala we-LCD, i-amplifier, isiguquli se-A/D kunye nezinye izixhobo zisebenzisa itekhnoloji yamva nje, ngokuchaneka okuphezulu, iimpawu zesisombululo esiphezulu, ujongano lolawulo lwe-analog microcomputer, ukusebenza okulula nokufanelekileyo, ukuphucula kakhulu ukusebenza kakuhle uvavanyo.
1. Ijika lexesha lamandla lingabonakaliswa ngokubonakalayo ngexesha lovavanyo;
2. Ekupheleni kovavanyo olunye, i-static coefficient kunye ne-dynamic friction coefficient ilinganiswa ngaxeshanye.
I-3, Iqela ledatha ye-10 yokuvavanya ingarekhodwa ngokuzenzekelayo, kwaye ibale ixabiso eliphezulu, ixabiso elincinci, ixabiso eliphakathi, ukuphambuka okusemgangathweni, i-coefficient of variation;
I-4, Uxinzelelo oluthe nkqo (ubunzima be-slider) lunokusetwa ngaphandle kwesizathu;
5, Isantya sovavanyo 0-500mm / min eqhubekayo adjustable;
I-6, isantya sokuBuyisa sinokumiselwa ngokungqongqo (ukuphucula kakhulu ukusebenza kovavanyo);
I-7, i-Dynamic friction coefficient data reference iyakwazi ukulungiswa ngokweyona meko.
