(I-China) YY9830A I-Automatic Kjeldahl Nitrogen Analyzer

Incazelo emfushane:

Isifinyezo:

Indlela ye-Kjeldahl iyindlela yakudala yokunqunywa kwe-nitrogen. Indlela ye-Kjeldahl isetshenziswa kabanzi

ukunquma izinhlanganisela ze-nitrogen enhlabathini, ukudla, ukufuywa kwezilwane, imikhiqizo yezolimo, ukudla kanye

eminye imikhiqizo. Ukunqunywa kwesampula ngale ndlela kudinga izinqubo ezintathu: isampula

ukugaya, ukuhlukaniswa kwe-distillation kanye nokuhlaziywa kwe-titration

Le nkampani ingelinye lamayunithi asungula izinga likazwelonke le-“GB/T 33862-2017 full

(semi-) othomathikhi i-Kjeldahl nitrogen analyzer”, ngakho-ke imikhiqizo yathuthukiswa futhi yakhiqizwa

I-Kjeldahl nitrogen analyzer ihlangabezana nezinga le-“GB” kanye namazinga ahlobene namazwe ngamazwe.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izici Zomkhiqizo:

I-1) Uhlelo lokulawula lusebenzisa isikrini sokuthinta umbala wama-intshi angu-10, ukuguqulwa kwesiShayina nesiNgisi, kulula ukuyisebenzisa

2) Ukuphathwa kwamalungelo emazingeni amathathu, amarekhodi e-elekthronikhi, amalebula e-elekthronikhi, kanye nezinhlelo zemibuzo yokulandelela ukusebenza kuhlangabezana nezidingo zesitifiketi ezifanele

I-3) Uhlelo luvala ngokuzenzakalelayo emizuzwini engama-60 ngaphandle kokusebenza, lusindisa amandla, ukuphepha kanye nokuqiniseka

4)★ Imiphumela yokuhlaziywa kwevolumu yevolumu yokufaka okuzenzakalelayo nokugcinwa, ukubonisa, ukubuza, ukuphrinta, neminye imisebenzi yemikhiqizo ezenzakalelayo

5)★ Ithebula lombuzo wethuluzi elakhelwe ngaphakathi le-protein ukuze abasebenzisi baxhumane nalo, babuze futhi babambe iqhaza ekubalweni kwesistimu, lapho i-coefficient =1 umphumela wokuhlaziya uthi “okuqukethwe kwe-nitrogen” lapho i-coefficient > umphumela wokuhlaziya ongu-1 uguqulelwa ngokuzenzakalelayo “kumaprotheni. okuqukethwe” futhi kuboniswe, kugcinwe futhi kuphrintwe

6) Isikhathi se-distillation sisethwe ngokukhululekile kusuka kumasekhondi angu-10 kuya kumasekhondi angu-9990

I-7) Izinga lokugeleza kwe-steam lingalungiswa lisuka ku-1% liye ku-100% ukuze kusetshenziswe amasampula okuhlushwa ahlukene

8) Ukukhipha imfucuza okuzenzakalelayo epayipini lokupheka kunciphisa umfutho wokusebenza kwabasebenzi

9)★ Vala ipayipi le-alkali lokuhlanza okuzenzakalelayo ukuze uvimbele ukuvaleka kwamapayipi futhi uqinisekise ukunemba kokunikezwa kwamanzi

10) Idatha ingagcinwa kuze kufike ezigidini ezingu-1 ukuze abasebenzisi baxhumane nabo

11) 5.7CM othomathikhi iphepha ukusika iphrinta ezishisayo

I-12) Uhlelo lwe-steam lwenziwe ngensimbi engagqwali engama-304, ephephile futhi enokwethenjelwa

13) I-cooler yenziwe ngensimbi engagqwali engu-304, enesivinini sokupholisa ngokushesha kanye nedatha yokuhlaziya ezinzile.

14) Uhlelo lokuvikela ukuvuza ukuze kuqinisekiswe ukuphepha kwabaqhubi

I-15) Umnyango wezokuphepha kanye nesistimu ye-alamu yomnyango wokuphepha ukuqinisekisa ukuphepha komuntu siqu

I-16) Uhlelo lokuvikela olulahlekile lwe-tube deboiling luvimbela ama-reagents kanye ne-steam ekulimazeni abantu

I-17) I-alamu yokushoda kwamanzi yesistimu ye-Steam, yeka ukuvimbela izingozi

18) I-alamu yokushisa ebhodweni le-steam, yeka ukuvimbela izingozi

I-19) I-alamu ye-Steam overpressure, ukuvala, ukuvimbela izingozi

20) Isampula ye-alamu yokushisa ngokweqile, ukuvala shaqa ukuvimbela ukukhuphuka kwezinga lokushisa kwesampula futhi kuthinte idatha yokuhlaziya

I-21) Ukuqapha ukugeleza kwamanzi okupholisa ukuvimbela ukugeleza kwamanzi okwanele okubangelwa ukulahlekelwa kwesampula, okuthinta imiphumela yokuhlaziya
