Ngoluhlu lokulinganisa i-DN15-DN1000 kunye ne-velocities ukusuka kwi-0.2-15 m / s, ithatha i-low-conductivity yamanzi abuyiselweyo (≥5 μS / cm ye-non-aqueous media) ngaphandle koxinzelelo lwe-drops, ukuxhasa imijikelezo ye-CIP / SIP ukuya kwi-180 ° C kwizicwangciso zokwahlula. Iziphumo ezifana ne-4-20 mA, i-pulse, kunye ne-RS485 / i-Modbus idibanisa ngokungenamgudu kunye ne-SCADA ekhoyo, ibonelela ngoxilongo lwexesha lokwenyani ukuthintela ukudodobala kwizikhululo ze-booster.

Ngokwenyani, i-SUP-LDGS ibhulorho imvelaphi yamanzi amdaka ekusetyenzisweni kwakhona kwexabiso elongeziweyo, iquka ukuzibophelela kwe-Sinomeasure kwisixhobo esomeleleyo, esiguquguqukayo esilungelelaniswa nemigaqo yococeko lwehlabathi ngelixa kusonjululwa imingeni yasekhaya efana nokuqukuqela okubangelwa yimonsoon.

Ukungena nzulu kubuchule bayo bobunjineli, i-SUP-LDGS izingca ngoluhlu lweenkcukacha eziqinisekisa ukuthembeka ekufuneni umiselo lwezococeko, njengoko kuchaziwe kuxwebhu lobugcisa lweSinomeasure. Ukuchaneka kufikelela ku-±0.5% wezinga (okanye ±2 mm/s kwi-<1 m/s), kunye ne-0.2% ukuphinda-phinda ukudluliselwa kokugcinwa, ukuqinisekisa ukulandeleka kokuthunyelwa kokutya okuphicothiweyo. Izinto ze-Liner-PFA, i-F46, i-PTFE, i-FEP, okanye i-neoprene-inikezela ukuxhathisa ukubola okulungiselelwe kwi-pH 0-14 yemidiya, ngelixa ukhetho lwe-electrode (i-Hastelloy C-276, i-titanium, i-tantalum, okanye i-platinum-iridium) inyamezela i-sanitizers enobudlova ngaphandle kokukhupha.

Ukunyamezela ubushushu be-Fluid spans -20 ° C ukuya kwi-160 ° C, kunye nokusebenza kwe-ambient ukusuka kwi-20 ° C ukuya kwi-60 ° C kunye ne-IP65 / IP67 ukukhuselwa uthuli kunye nokucwiliswa. Iimfuno zamandla zithobekile (AC 85-265V okanye i-DC 24V), umzobo <0.65W, kunye nokufakela ukuguquguquka kubandakanya i-flange (DIN / JIS / ANSI), i-clamp, okanye i-thread mounts, kunye ne-cable glands ukuya kwi-11mm. Izahluko ezinobungqina bokudubula (ExiaIICT6 Gb) zilungele iindawo eziguquguqukayo, kunye noyilo lwemodyuli yemitha ivumela ii-transmitter ezikude ukuya kuthi ga kwi-50m, iququzelela ulondolozo kwimozulu efumileyo ye-Philippine. Ezi parameters, eziqinisekisiweyo phantsi kwemigangatho ye-JB/T 9248-2015, zigxininisa ubude beminyaka eyi-10 ye-electrode, engaphezulu lee kunoomatshini abanokunxitywa kwi-viscous slurries efana nokubuyiswa kwe-pulp.

Iimpawu eziphambili ziphakamisa ngakumbi i-SUP-LDGS njengendawo yokugcina amandla ephantsi yolawulo lokuhamba oluchanekileyo. I-excitation yayo ye-dual-frequency excitation iqinisa izibonakaliso kwiimeko zokutshiza okanye ukuhamba okuphantsi, ukuphelisa ingxolo evela kumaqamza okanye izinto eziqinileyo ezixhaphake ngokucocwa kwamanzi amdaka, ngelixa i-liner non-conductive ithintela ukwakhiwa, ukwandisa ixesha lenkonzo.

Ukufunyanwa kombhobho odibeneyo ongenanto ngokusebenzisa i-algorithms ephezulu kumisa ukufundwa kobuxoki, kunye nemisebenzi yokuzixilonga, ifikeleleke ngeprotocol ye-HART, i-flag electrode coatings okanye ukuphulwa kwe-liner kwangaphambili, ukunciphisa ixesha lokuphumla elingacwangciswanga ukuya kuthi ga kwi-30%. Ukugqwesa kococeko, uqhagamshelo olukhawulezayo lokuqhawula i-tri-clamp luvumela ukuchithwa kwesixhobo ukuze kuqinisekiswe, ukucutha ixesha lokulungiselela uphicotho, kunye nokungabikho kweendawo ezifileyo kuxhasa ukuqinisekiswa okungenazintsholongwane ngokwezikhokelo ze-GMP.

Xa kuthelekiswa neemitha ze-ultrasonic, ukungakhathali kwayo kwiiyantlukwano zoxinanisongexeshapHuhlengahlengisoinika ulawulo olungqongqo, inyusa izivuno nge-5-10% kwimisebenzi yokudibanisa. Ezi mpawu, zidityaniswe namandla okuqukuqela okuphindwe kabini okugungxulwa umva, zenza i-SUP-LDGS ingabi sisilinganisi nje kuphela kodwa ibe yi-asethi esebenzayo ekuqinisekiseni imfezeko yamanzi amdaka asuka kwiivathi zonyango zeMetro Manila ukuya kutsho kumjelo wemibhobho yococeko.

I-SUP-LDGS ifumana usetyenziso oluguquguqukayo kuwo wonke amashishini apho imfezeko yococeko ibaluleke kakhulu, ngakumbi kwiprojekthi yePhilippine yokusetyenziswa kwakhona kwamanzi amdaka e-ecosystem. Kukutya kunye nesiselo, ibeka esweni izongezo zezithako ezifana namanzi kwi-syrup dilution okanye i-post-pasteurization epholileyo, igcina i-batch consistency phakathi kwe-viscosities eguquguqukayo ukuya kwi-1000 cP.

Imigca yamachiza ixhamla ekulandeleni kwayo ekuhanjisweni kwamanzi ahlambulukileyo okanye i-tablet granulation, ephakamisa iilogi ezithobela i-FDA zokuthumela iziqinisekiso zokuthumela ngaphandle. Ngaphaya kokucutshungulwa kobisi kuyayikhulisa ukuze kumiswe ubisi, ngelixa abadidiyeli botywala belandela umkhondo we-wort equkuqelayo kwiitanki zokuvubela, ngelixa bebambelela kucoceko lwe-3-A.

Kwiimeko zamanzi amdaka njengale ndawo yaseManila, yongamela imijelo ebuyiselweyo yonkcenkceshelo ngezolimo, ukuthintela ukunkcenkceshela okugqithisileyo okunetyuwa eninzi kumasimi erayisi.

Amacandelo emichiza ayisebenzisela ukungcola okungathathi hlangothi kwi-batch reactors, kunye nezithambiso zokuxuba i-emulsion, apho ukulinganisa okuchanekileyo kunciphisa inkunkuma. Nge-scalability ukusuka kwi-lab-scale ye-DN15 ukuya kwi-DN1000 yoshishino, kunye noxinzelelo ukuya kwi-1.6-4.0 MPa, ixhasa amanyathelo okukhutshwa kolwelo oluyi-zero kwiindawo ezikufutshane nemigodi njenge-Cebu, ukuphinda kusetyenziswe i-brines ngaphandle kwemingcipheko ye-microbial. Ekugqibeleni, olu setyenziso luguqula amanzi acociweyo ukusuka kumthwalo ukuya kwi-boon, ukuqhuba ukusebenza kakuhle kwiindawo ezinqongopheleyo zamanzi.
