Katoa Aunoa Kjeldahl Nitrogen Analyzer
Ko te punaha whakahaere he 7.5 inihi te nui o te mata whakaatu pa tae, te papa whakahaere PTM SIEMENS, ka taea te hono ki te kiore ahokore.
He atanga whakaatu Hainamana me te mahi taunekeneke tangata-miihini tino pai, a he ngawari te whakahaere me te mohio ki te mahi whakahaere
E rua nga momo mahi, te tātari aunoa me te tātari a-ringa, ka tutuki nga whakaritenga o nga whakamatautau rereke.
Ko te atanga whakawhitiwhiti raraunga USB, te whirihoranga paerewa, he watea mo nga kaiwhakamahi ki te uiui i nga raraunga mata.
Kiore ahokore, whirihoranga paerewa
Ka tangohia e ia te papu diaphragm-a-whaiaro i kawemai me te kete taketake mai i Ingarangi ki te whangai wai me te tino taru i te papu diaphragm pneumatic e whakamahia ana e te maha o nga wheketere o roto.Ko te whangai i te wai ma te papu-a-whaiaro ka taea te whakanoho i te peera whangai-wai ki raro i te papa whakahaere he painga ki te whakaora pai i te ruuma taiwhanga, te kowhiri i te peera wai-whangai nui, etc.
Ko te punaha whakahaere matua kei te whakamahi i te papa whakahaere PLC matatau: he pono, he tika hoki te mana whakahaere.
Pūnaha whakawhiti aunoa wai whakamatao: ina he mamaoa, ka huri aunoa te wai whakamahana;ka kore he mamaoa, ka weto aunoa te wai whakamatao.Ka taea e ia te whakaora i te wai whakamatao ki te nui rawa atu me te karo i te ngaronga kino ka puta mai na te mea ka wareware te kaiwhakahaere ki te whakaweto i te puna wai.
Te mahi i mua i te wera: i te wa e timata ana, kua rite ranei, ka 80 ℃ te pāmahana o te rango mamaoa.Ina hiahiatia te ine me te tātari, ka tere te whakaputa mamaoa ka whakapoto i te wa tatari.
Mahi waimeha aunoa ki te karo waikawa kaha me te alkali overreaction: i mua i te tāpiri kawakore, me tāpiri te nui tika o te wai māturu ki te waimeha tauira waikawa kaha ki te karo i te tauhohenga kaha ina tutaki waikawa kaha alkali kaha.
Papatono mo te horoi aunoa kapu titration: ka taea e ia te karo i te wai toenga kore-kore e awe i te tauira iti-iti, i te tauira patea ranei hei whakapai ake i te tika o te punaha me te pono.
Ko te tuku aunoa motuhake me te mahi kohikohinga o te para ngongo nakunaku: i muri i te otinga o te titration, ka tukuna aunoatia te wai para ngongo nakunaku ka kohia kaha.Ka tino pai ake te mahi aunoa, ka whakaiti i te kaha o te mahi a nga kaimahi, ka whakatau i te kohinga me te maimoatanga o te tātaritanga para wai me te whai ki nga paerewa whakahaere o te taiwhanga pai.
Ko te tukunga aunoa me te kohikohinga o te titration para wai: te papu whaiaro-priming pump aunoa i te titration i te taputapu tuku para para wai ka pai ake te wai para i roto i te rerenga kapu titration me te tino pai me te ngawari me te mahi o te hononga paipa no te mea he rite tonu te tomokanga ki te kohinga. wai para o te ngongo nakunaku.
Ko nga paipa katoa o te taputapu ka tango i nga taonga kawemai me te hanganga hiri ka taea te whakanui i te oranga o te taputapu.
Pūnaha whakatikatika aunoa o te titration kukū wai (mol)
Ko te aratau takirua o te tikanga whakatikatika aunoa e whakakore ana i nga hapa me nga tikanga whakauru tika tuku iho
Tikanga whakatikatika aunoa e whakakore ana i nga hapa: ka whakakorea e tenei tikanga nga hapa o te punaha na te rereketanga i waenga i te whakatikatika o waho o te taputapu me te titration taputapu (calibration) ka piki ake te tika o te punaha.
Ko te ngongo nakunaku he whakamarumaru watea: ka kore te punaha e wera ki te kore e whakauruhia te ngongo nakunaku ki roto;
He whakamarumaru kuaha haumaru: ki te kore te kuaha haumaru e kumea ki raro, ka kore te punaha e wera;
Te mahi whakakii-wai-aunoa o te rango mamaoa: ki te kore he wai o te kaihanga mamaoa, karekau ranei te taumata o te wai e tino nui, ka whakakiia e te punaha te wai kia kore e wera me te kore wai;
Te whakamarumaru i te pehanga mamaoa: ina he tiketike rawa te pehanga o te punaha hanga mamaoa na te aukati me te pakaru o te paipa mamaoa, te paipa mamaoa rereke ranei, ka mutu te rere o te punaha me te whakaohooho;
Te parenga rerenga: ka pakaru te hiko o te punaha, ka raru ranei te kaiwhakahaere, ka whakawetohia e te punaha te hiko ka tapahia te hiko kia mohio kei te noho haumaru te kaiwhakahaere.
