Udindo wa makina odzaza nayitrogeni yamadzimadzi pakudzaza nayitrogeni yamadzimadzi muzinthu zam'chitini

Nayitrogeni yamadzimadzi imatengedwa kuchokera ku thanki yosungiramo nayitrogeni yamadzimadzi kupita ku cholekanitsa cha gasi ndi madzi kudzera mu payipi ya vacuum yokwera kwambiri. Nayitrogeni yamadzimadzi ya magawo awiri ya gasi imalekanitsidwa mwachangu kudzera mu cholekanitsa cha gasi ndi madzi, ndipo gasi ndi nayitrogeni zimatulutsidwa zokha kuti zichepetse kukhuta kwa nayitrogeni yamadzimadzi. Cholekanitsa gasi ndi madzi Pambuyo poti nayitrogeni yamadzimadzi mkati mwake yayeretsedwa, nayitrogeni yamadzimadzi imalekanitsidwa ndi nayitrogeni yamadzimadzi, ndipo nayitrogeni yamadzimadzi yoyera imalowetsedwa mu makina ojambulira nayitrogeni. Mlingo wamadzimadzi wa cholekanitsa gasi ndi madzi umayendetsedwa zokha kuti zitsimikizire kuti mulingo wa nayitrogeni yamadzimadzi ndi mutu wopanikizika wosasinthasintha ndizokhazikika, kuti zitsimikizire kuti makina odzaza nayitrogeni yamadzimadzi sakhudzidwa ndi kusinthasintha kwa kuthamanga pamene mujambulira nayitrogeni, komanso kukhazikika kwa jakisoni wa nayitrogeni kumakhudzidwa, ndipo mtengo wa CPK mu botolo umakhudzidwa.

Udindo wa makina odzaza nayitrogeni yamadzimadzi pakudzaza nayitrogeni yamadzimadzi muzinthu zam'chitini:

Pambuyo poti kudzazidwa kwatha komanso musanalowe mu chivundikiro, ukadaulo wamakono wodzaza nayitrogeni yamadzi umagwiritsidwa ntchito kutsitsa nayitrogeni yamadzi molondola komanso mochuluka pa -196°C, kenako ndikutseka nayitrogeni yamadzi nthawi yomweyo. Nayitrogeni yamadzi imayamwa kutentha kwakanthawi kochepa ndikusanduka nayitrogeni ya gasi. , Kuchuluka kwake kumawonjezeka ka 700.

1. Kupanikizika kwamkati kumapangidwa mu chidebe/botolo, komwe kumakhala kosavuta kugwira, ndipo kumawonjezera kumva kwa dzanja. Sipanga botolo losweka litazizira, ndipo silidzawonongeka panthawi yolongedza, kuyika zinthu pamodzi ndi kuigwira.

2. Tulutsani mpweya (makamaka mpweya) mu chidebe/botolo, kuti nthawi yogwiritsira ntchito mankhwalawa ikhale yayitali komanso kuti kukoma kwake kukhale bwino.

3. Zitini za aluminiyamu sizivuta kuzipanga dzimbiri ndipo ndizoyenera kuzisungira mufiriji.

Njira yothira nayitrogeni yamadzimadzi:
Kapangidwe koyambira ka zida zazikulu: thanki yosungiramo nayitrogeni yamadzimadzi, payipi yonyamula madzi yamadzimadzi yotsekedwa kwambiri yokhala ndi vacuum yambiri komanso yotsekedwa ndi zingwe zambiri (payipi ya vacuum mwachidule), PHASE SEPARATOR, makina ojambulira nayitrogeni, ndi makina owongolera okha.
