Zofunika Pakuperekedwa kwa Nayitrojeni Wamadzi Wamu Laboratory: Matanki Odzikakamiza Amadzimadzi a Nayitrojeni

Mwachitsanzo, Shengjie Liquid Nitrogen Replenishment Series imapereka zotengera zaposachedwa kwambiri zosungirako zamadzimadzi zotentha kwambiri.Zogulitsazi zimapangidwira ogwiritsa ntchito ma labotale ndi mafakitale kuti azisungira nayitrogeni wamadzimadzi kapena kubwezeretsanso.

Pokhala ndi kapangidwe kachitsulo chosapanga dzimbiri, amatha kupirira zovuta zogwirira ntchito pomwe amachepetsa kutayika kwamadzi.Chilichonse chomwe chili pamndandandawu chimakhala ndi valavu yolimbikitsira, valavu yothira, choyezera kuthamanga, valavu yachitetezo, ndi valavu yotulutsa mpweya.Kuphatikiza apo, mitundu yonse imakhala ndi ma caster anayi osunthika kuti azitha kuyenda mosavuta pakati pa malo osiyanasiyana.

Kuphatikiza pa kubwezeretsanso matanki a nayitrogeni amadzimadzi, matanki amadzimadzi amadzimadzi a nayitrogeni amathanso kudzazana.Kuti muchite izi, konzani zida monga ma wrenches pasadakhale.Musanabaya jekeseni wa nayitrojeni wamadzimadzi, tsegulani valavu yotsegulira, tsekani valavu yolimbikitsa ndi kukhetsa valavu, ndipo dikirani kuti kuwerengera kwa pressure kutsika kufika paziro.

Kenaka, tsegulani valavu ya thanki yomwe imafuna kubwezeretsanso, gwirizanitsani ma valve awiri okhetsa ndi payipi ya kulowetsedwa, ndikumangitsa ndi wrench.Kenako, tsegulani valavu yolimbikitsira ya tanki yosungiramo nayitrogeni yamadzimadzi ndikuwona kuchuluka kwa kuthamanga.Mulingo wa kuthamanga ukakwera pamwamba pa 0.05 MPa, mutha kutsegula ma valve onse awiri kuti muwonjezere madziwo.

Ndikofunikira kudziwa kuti pobaya nayitrojeni wamadzimadzi kwa nthawi yoyamba kapena pakapita nthawi yayitali osagwiritsa ntchito, ndi bwino kubaya 5L-20L wamadzi wa nayitrogeni kuti muziziritse (pafupifupi mphindi 20).Chingwe chamkati cha chidebecho chikazirala, mutha kubaya nayitrojeni wamadzimadzi kuti mupewe kuthamanga kwambiri komwe kumadza chifukwa cha kutentha kwamkati kwamkati, komwe kungayambitse kusefukira kwa nayitrogeni komanso kuwonongeka kwa mavavu oteteza chitetezo.

Pogwira ntchito, ogwira ntchito ayenera kuvala zida zoyenera zodzitetezera kuti asavulazidwe ndi nitrogen wamadzimadzi.Mukamalipira nayitrogeni wamadzimadzi mu akasinja amadzimadzi a nayitrogeni, chifukwa cha chitetezo, sayenera kudzazidwa kwathunthu, ndikusiya pafupifupi 10% ya voliyumu ya geometric ya chidebe ngati danga la gasi.

Mukamaliza kubwezeretsanso nayitrogeni yamadzimadzi, musatseke valavu yotsegulira ndikuyika nati yotsekera kuti mupewe kulumpha pafupipafupi kwa valavu yachitetezo chifukwa cha kutentha kochepa komanso kuwonongeka.Lolani tanki kuyimilira kwa maola osachepera awiri musanatseke valavu yotsegulira ndikuyika nati wotseka.
