Niba hari inenge mu iyungurura rya hepa n'ishyirwa ryaryo, nk'umwobo muto mu iyungurura ubwaryo cyangwa utudomo duto duterwa no gushyirwamo ibintu birebire, ingaruka zo gusukura ziteganijwe ntizigerwaho. Kubwibyo, nyuma yo gushyirwamo cyangwa gusimburwa na hepa, ugomba gukora ikizamini cyo kuva amazi kuri iyungurura n'ishyirwamo.
1. Intego n'urwego rwo gupima amazi asohoka:
Intego yo gupima: Mu gusuzuma aho akayunguruzo ka hepa kamenetse, menya inenge za akayunguruzo ka hepa n'uko kashyizweho, kugira ngo hafatwe ingamba zo gukosora.
Ingano yo gupima: ahantu hasukuye, intebe yo gukoreraho amazi ya laminar na filtre ya hepa ku bikoresho, nibindi.
2. Uburyo bwo gutahura amazi asohoka:
Uburyo bukunze gukoreshwa cyane ni uburyo bwa DOP bwo gutahura aho amazi aturuka (ni ukuvuga gukoresha DOP solvent nk'isoko y'umukungugu no gukoresha icyuma gipima umwuka kugira ngo hamenyekane aho amazi aturuka). Uburyo bwo gupima aho amazi aturuka bushobora kandi gukoreshwa mu kumenya aho amazi aturuka (ni ukuvuga gukoresha ivumbi ryo mu kirere nk'isoko y'umukungugu no gukorana n'icyuma gipima aho amazi aturuka kugira ngo hamenyekane aho amazi aturuka).
Ariko, kubera ko gusoma ibice by’amazi ari igipimo cy’itsinda, ntabwo byoroshye kubisuzuma kandi umuvuduko wo kugenzura ugenda buhoro; byongeye kandi, ku ruhande rw’umuyaga uzamuka kuri filtre ya hepa iri kugeragezwa, ivumbi ry’ikirere rikunze kuba rito, kandi umwotsi w’inyongera urakenewe kugira ngo hamenyekane byoroshye amazi ava. Uburyo bwo gusuzuma ibice by’amazi bukoreshwa mu kumenya amazi ava. Uburyo bwa DOP bushobora gukosora ibyo bibazo, bityo ubu uburyo bwa DOP bukoreshwa cyane mu kumenya amazi ava.
3. Ihame ry'imikorere yo gupima amazi aturuka mu buryo bwa DOP:
Aerosol ya DOP isohoka nk'isoko y'umukungugu ku ruhande rw'umuyaga ruzamuka rw'akayunguruzo gafite ubushobozi bwinshi kageragezwa (DOP ni dioctyl phthalate, uburemere bwa molekile ni 390.57, kandi utwo duce tuba turi uruziga nyuma yo gutera).
Igipimo cy'umwuka ushyushye gikoreshwa mu gupima ku ruhande rw'umuyaga umanuka. Ingero z'umwuka zakusanyijwe zinyura mu cyumba cy'umuvuduko w'umwuka ushyushye. Urumuri rutatanye ruturuka ku mwuka urimo ivumbi unyura muri uwo mwuka ruhinduka amashanyarazi binyuze mu ngaruka z'amashanyarazi n'ingufu z'umwuka ushyushye, kandi rugaragazwa vuba na mikoroammetero, ingano y'umwuka ushyushye ishobora gupimwa. Icyo ikizamini cya DOP gipima mu by'ukuri ni igipimo cy'ubwinjirire bw'icyuma cya hepa.
Imashini ikora DOP ni igikoresho gitanga umwotsi. Iyo DOP isutswe mu gikoresho gitanga amashanyarazi, umwotsi wa aerosol ukorwa munsi y’igitutu runaka cyangwa imiterere y’ubushyuhe, woherezwa ku ruhande rw’umuyaga ruzamuka rw’akayunguruzo gakomeye (amazi ya DOP arashyuha kugira ngo akore umwuka wa DOP, maze umwuka ugashyuha mu gikoresho cyihariye cya Kondensate mu tudomo duto mu bihe bimwe na bimwe, ukureho utudomo tunini cyane n’ututo cyane, hagasigara gusa utuntu duto twa 0.3um, maze DOP y’igihu yinjire mu muyoboro w’umwuka);
Fotometero za Aerosol (ibikoresho byo gupima no kwerekana ingano ya aerosol bigomba kugaragaza igihe cyo gupima, kandi bishobora gukoreshwa gusa iyo byarenze igihe cyo gupima kandi biri mu gihe cyo gupima);
4. Uburyo bwo gukora ikizamini cyo kumenya aho amazi aturuka:
(1). Gutegura uburyo bwo kumenya aho amazi aturuka
Tegura ibikoresho bikenewe mu gutahura amazi asohoka n'igishushanyo mbonera cy'aho umwuka uturuka mu buryo bwo gusukura no gukonjesha mu gace kagomba gusuzumwa, kandi umenyeshe ikigo gishinzwe gutunganya no gukonjesha kugira ngo kizabe kiri aho ku munsi wo kubona amazi asohoka kugira ngo gikore ibikorwa nko gushyira kole no gusimbuza ibyuma bya hepa.
(2). Igikorwa cyo kumenya aho amazi aturuka
①Reba niba urugero rw'amazi rwa DOP mu cyuma gitanga aerosol ruri hejuru y'urugero rwo hasi, niba rudahagije, rugomba kongerwamo.
②Huza icupa rya azote kuri generator ya aerosol, fungura switch y'ubushyuhe ya generator ya aerosol, hanyuma utegereze kugeza igihe itara ritukura rihindukiye icyatsi kibisi, bivuze ko ubushyuhe bugeze kuri (hafi 390 ~ 420℃).
③Huza impera imwe y'umuyoboro w'igerageza ku gice cyo hejuru cy'igerageza cya fotometero ya aerosol, hanyuma ushyire indi mpera ku ruhande rw'injira ry'umwuka (uruhande rwo hejuru) rw'akayunguruzo ka hepa kari gupimwa. Fungura akayunguruzo ka fotometero hanyuma uhindure agaciro k'igerageza kuri "100".
④ Fungura switch ya azote, genzura umuvuduko kuri 0.05 ~ 0.15Mpa, fungura buhoro buhoro valve y'amavuta ya moteri ya aerosol, genzura agaciro k'igerageza rya fotometero kuri 10 ~ 20, hanyuma winjize mu gipimo cyo hejuru nyuma y'uko agaciro k'igerageza gahagaze neza. Kora ibikorwa byo gusuzuma no kugenzura bikurikira.
⑤Huza impera imwe y'umuyoboro w'ikizamini ku gice cyo hasi cy'ikizamini cya fotometero y'umwuka, hanyuma ukoreshe indi mpera, umutwe w'ikizamini, kugira ngo urebe uruhande rw'aho umwuka usohoka rw'akayunguruzo n'agakingirizo. Intera iri hagati y'umutwe w'ikizamini n'akayunguruzo ni nka cm 3 kugeza kuri 5, ku gice cy'imbere cy'akayunguruzo harasuzumwa inyuma no inyuma, kandi umuvuduko w'igenzura uri munsi ya cm 5/s.
Isuzuma rikubiyemo ibikoresho byo kuyungurura, isano iri hagati y’ibikoresho byo kuyungurura n’umukara wabyo, isano iri hagati ya gasket y’umukara wa filter n’umukara wa support w’itsinda ry’abayungurura, isano iri hagati y’umukara wa support n’urukuta cyangwa igisenge kugira ngo harebwe utwobo duto two hagati twa filter n’ibindi byangiritse muri filter, seal z’umukara, seal z’umukara, n’amazi asohoka muri filter.
Gupima amazi ya hepa mu bice bisukuye biri hejuru ya 10000 muri rusange biba rimwe mu mwaka (bimara kabiri mu mwaka mu bice bidafite umwanda); iyo hari ubusumbane bugaragara mu mubare w'udukoko tw'umukungugu, bagiteri zitera umwanda, n'umuvuduko w'umwuka mu gukurikirana buri munsi ahantu hasukuye, hagomba kandi gukorwa uburyo bwo kumenya amazi yavuyemo.
