Niba hari inenge muri hepa muyungurura no kuyishyiraho, nk'imyobo mito muyungurura ubwayo cyangwa uduce duto duto twatewe no kwishyiriraho, ingaruka zagenewe kwezwa ntizagerwaho.Kubwibyo, nyuma ya hepa muyunguruzi yashizwemo cyangwa isimbuwe, igomba gukora ikizamini cyo kumeneka no kuyungurura.
1. Intego nubunini bwo gutahura:
Intego yo gutahura: Mugerageze kumeneka kwa hepa filteri, menya inenge ya filteri ya hepa nogushiraho, kugirango ufate ingamba zo gukosora.
Urwego rwo gutahura: ahantu hasukuye, intebe yakazi ya laminar hamwe na hepa muyunguruzi kubikoresho, nibindi.
2. Uburyo bwo gutahura:
Uburyo bukoreshwa cyane nuburyo bwa DOP bwo kumenya ibimeneka (nukuvuga, gukoresha DOP solvent nkisoko yumukungugu no gukorana na fotometero ya aerosol kugirango umenye ibimeneka).Uburyo bwo gusikana ivumbi rishobora no gukoreshwa kugirango hamenyekane imyanda (ni ukuvuga, gukoresha umukungugu wo mu kirere nkisoko yumukungugu kandi ugakorana na compteur kugirango umenye ibimeneka.).
Ariko, kubera ko ibice byo gusoma bisomwa ni ugusoma hamwe, ntabwo bifasha gusikana kandi umuvuduko wo kugenzura uratinda;hiyongereyeho, kuruhande rwo hejuru rwa filteri ya hepa mugeragezwa, umukungugu wo mu kirere ukunze kuba muke, kandi umwotsi winyongera urasabwa kugirango byoroshye gutemba.Uburyo bwo kubara ibice bikoreshwa mugutahura imyanda.Uburyo bwa DOP burashobora gusa kuzuza izo nenge, ubu rero uburyo bwa DOP burakoreshwa cyane mugutahura.
3. Ihame ryakazi ryuburyo bwa DOP gutahura:
DOP aerosol isohoka nkisoko yumukungugu kuruhande rwo hejuru ya filteri ikora neza igeragezwa (DOP ni dioctyl phthalate, uburemere bwa molekile ni 390.57, naho ibice ni serefegitura nyuma yo gutera).
Ifoto ya aerosol ikoreshwa muguhitamo kuruhande rwo hasi.Icyitegererezo cy'ikirere cyegeranijwe kinyura mu cyumba cyo gukwirakwiza fotometero.Umucyo utatanye ukomoka kuri gaze irimo umukungugu unyura kuri fotometero uhindurwamo amashanyarazi n'ingaruka za fotoelectric hamwe no kongera umurongo, kandi bigaragazwa vuba na microammeter, ibipimo bya aerosol bishobora gupimwa.Icyo ikizamini cya DOP gipima mubyukuri ni igipimo cyo kwinjira cya hepa muyunguruzi.
Imashini ya DOP ni igikoresho gitanga umwotsi.Nyuma ya DOP solvent isutswe mubikoresho bya generator, umwotsi wa aerosol ubyara umusaruro mukibazo runaka cyangwa ubushyuhe hanyuma woherezwa kuruhande rwo hejuru rwunguruzi rukora neza (amazi ya DOP arashyuha kugirango akore amavuta ya DOP, kandi amavuta ni ashyutswe muri Condensate yihariye mubitonyanga bito mubihe bimwe, ukureho ibitonyanga binini cyane kandi bito cyane, hasigara ibice 0.3um gusa, kandi igihu DOP cyinjira mumuyoboro wikirere);
Amafoto ya aerosol (ibikoresho byo gupima no kwerekana ingufu za aerosol bigomba kwerekana igihe cyemewe cya kalibrasi, kandi gishobora gukoreshwa gusa iyo batsinze kalibrasi kandi kiri mugihe cyemewe);
4. Uburyo bwo gukora ikizamini cyo gutahura:
(1).Gutegura gutahura
Tegura ibikoresho bisabwa kugirango hamenyekane ibimeneka hamwe na plan yo hasi yumuyoboro wogutanga ikirere cya sisitemu yo kweza no guhumeka ikirere muri kariya gace igomba kugenzurwa, kandi umenyeshe uruganda rukora ibikoresho byo kweza no guhumeka ikirere ruzaba ruri kumunsi wo kumeneka. gutahura kugirango ukore ibikorwa nko gushiraho kole no gusimbuza hepa muyunguruzi.
(2).Igikorwa cyo gutahura
CkReba niba urwego rwamazi ya DOP solvent muri generator ya aerosol iri hejuru kurwego rwo hasi, niba bidahagije, igomba kongerwamo.
OnHuza icupa rya azote na generator ya aerosol, fungura ubushyuhe bwa moteri ya moteri ya aerosol, hanyuma utegereze kugeza itara ritukura rihindutse icyatsi, bivuze ko ubushyuhe bugeze (hafi 390 ~ 420 ℃).
OnHuza impera imwe yikizamini cyogupima icyambu cyo hejuru cyibizamini bya aerosol Photometer, hanyuma ushire kurundi ruhande kuruhande rwumuyaga (uruhande rwo hejuru) rwa filteri ya hepa igeragezwa.Fungura fotometero hanyuma uhindure agaciro k'ikizamini kuri "100".
UrnKomeza kuri azote, ugenzure umuvuduko kuri 0.05 ~ 0.15Mpa, fungura buhoro buhoro amavuta ya moteri ya moteri ya aerosol, ugenzure agaciro k'ibizamini bya fotometer kuri 10 ~ 20, hanyuma winjire murwego rwo hejuru rwapimwe nyuma yibizamini bimaze guhagarara.Kora ibikorwa byo gusikana no kugenzura.
OnHuza impera imwe yikizamini cya pompe kumurongo wogupima icyuma cya aerosol Photometer, hanyuma ukoreshe urundi ruhande, umutwe wicyitegererezo, kugirango usuzume uruhande rwumuyaga rwunguruzo na bracket.Intera iri hagati yicyitegererezo cyumutwe na filteri igera kuri cm 3 kugeza kuri 5, kuruhande rwimbere rwimbere muyungurura irasuzumwa inyuma n'inyuma, kandi umuvuduko wo kugenzura uri munsi ya 5cm / s.
Ingano yo kwipimisha ikubiyemo akayunguruzo, guhuza hagati yayunguruzo nibikoresho byayo, ihuriro hagati ya gasketi yikintu cyo kuyungurura hamwe nikigero cyo gushyigikira itsinda ryayunguruzo, ihuriro hagati yikintu gishyigikiwe nurukuta cyangwa igisenge kugirango ugenzure akayunguruzo gaciriritse ntoya hamwe nibindi byangiritse muyungurura, kashe ya kashe, kashe ya gasike, hamwe no kumeneka mumashanyarazi.
Kumenyekanisha inzira ya hepa muyungurura ahantu hasukuye hejuru yicyiciro 10000 muri rusange ni rimwe mumwaka (igice cyumwaka mugice cya sterile);mugihe haribintu bidasanzwe mububare bwumukungugu, bagiteri ziterwa nubutaka, n umuvuduko wikirere mugukurikirana burimunsi ahantu hasukuye, hagomba no gukorwa ubushakashatsi.
