T9008 BOD Water Quality Online Automatic Monitor

Kufotokozera Kwachidule:

Zitsanzo za madzi, yankho la potaziyamu dichromate digesting, yankho la siliva sulfate (siliva sulfate ngati chothandizira kuti chigwirizane bwino chingathandize kwambiri mafuta ophatikizika bwino) ndi chisakanizo cha sulfuric acid zimatenthedwa kufika pa 175 ℃, yankho la dichromate ion oxide la zinthu zachilengedwe pambuyo pa kusintha kwa mtundu, chowunikira kuti chizindikire kusintha kwa mtundu, ndi kusintha kwa kusinthika kukhala phindu la BOD ndi kugwiritsa ntchito kuchuluka kwa ma ion a dichromate azinthu zachilengedwe zomwe zimatha kusungunuka.

Zitsanzo za madzi, yankho la potaziyamu dichromate digesting, yankho la siliva sulfate (siliva sulfate ngati chothandizira kuti chigwirizane bwino chingathe kukhala cholunjika bwino cha mafuta ophatikizika) ndi chisakanizo cha sulfuric acid chimatenthedwa kufika pa 175 ℃, yankho la dichromate ion oxide la zinthu zachilengedwe pambuyo pa kusintha kwa mtundu, chowunikira kuti chizindikire kusintha kwa mtundu, ndi kusintha kwa kusinthika kukhala phindu la BOD ndi kugwiritsa ntchito kuchuluka kwa dichromate ion mu kuchuluka kwa zinthu zachilengedwe zomwe zimatha kusungunuka.

Magawo aukadaulo:

Ayi.	Dzina	Magawo aukadaulo
1	Mtundu wa Ntchito	Chogulitsachi ndi choyenera madzi otayira omwe amafunikira okosijeni wa mankhwala pakati pa 10 ~ 2000mg/L ndi kuchuluka kwa chloride komwe kuli kotsika kuposa 2.5g/L Cl-. Chitha kuwonjezeredwa ku madzi otayira omwe ali ndi kuchuluka kwa chloride komwe kuli kotsika kuposa 20g/L Cl- malinga ndi zomwe makasitomala akufuna.
2	Njira Zoyesera	Potaziyamu dichromate idagayidwa kutentha kwambiri komanso kutsimikiza kwa colorimetric.
3	Mulingo woyezera	10~2000mg/L
4	Malire Ochepa Ozindikira	3
5	Mawonekedwe	0.1
6	Kulondola	± 10% kapena ± 8mg/L (Tengani mtengo waukulu)
7	Kubwerezabwereza	10% kapena 6mg/L (Tengani mtengo waukulu)
8	Kuthamanga Kosalekeza	±5mg/L
9	Kuthamanga kwa Span	10%
10	Kuzungulira kwa muyeso	Osachepera mphindi 20. Kutengera ndi chitsanzo chenicheni cha madzi, nthawi yogaya chakudya ikhoza kukhazikitsidwa kuyambira mphindi 5 mpaka 120.
11	Nthawi yoperekera zitsanzo	Nthawi yosinthira (yosinthika), ola limodzi kapena njira yoyezera zinthu ingathe kukhazikitsidwa.
12	Kuzungulira kwa calibration	Kuyesa kokha (kusinthidwa masiku 1-99), malinga ndi zitsanzo zenizeni zamadzi, kuyesa kokha kumatha kukhazikitsidwa.
13	Nthawi yokonza	Nthawi yosamalira ndi yoposa mwezi umodzi, pafupifupi mphindi 30 nthawi iliyonse.
14	Kugwira ntchito kwa makina a anthu	Kukhudza chophimba chowonetsera ndi malangizo olowera.
15	Chitetezo chodziyang'anira	Kugwira ntchito kumadziyesa wekha, kusakhala bwino kapena kulephera kwa magetsi sikutaya deta. Kumachotsa zokha zinthu zotsalira zomwe zimagwirira ntchito ndikuyambiranso ntchito pambuyo pobwezeretsa kapena kulephera kwa magetsi.
16	Kusunga deta	Kusunga deta kosachepera theka la chaka
17	Mawonekedwe olowera	Sinthani kuchuluka
18	mawonekedwe otulutsa	Zotulutsa ziwiri za digito za RS485, Chotulutsa chimodzi cha analogi cha 4-20mA
19	Zikhalidwe Zogwirira Ntchito	Kugwira ntchito m'nyumba; kutentha 5-28℃; chinyezi chocheperako ≤90% (popanda kuzizira, palibe mame)
20	Kupereka Mphamvu ndi Kugwiritsa Ntchito	AC230±10%V, 50~60Hz, 5A
21	Miyeso	355×400×600(mm)
