Taw qhia
Txhua qhov kev xaiv ntawm cov khoom siv hauv kev tsim cov khoom siv portable suav nrog kev lag luam tawm. Lub twj tso kua dej me me yuav tsum ua kom tau raws li cov hom phiaj ntws thiab siab thaum haum cov peev nyiaj siv zog nruj, qhov chaw txwv, thiab cov suab nrov.
Engineers feem ntau nug:Qhov voltage version - 3V lossis 6V - yog qhov hu tau zoo?Puas yog 40-60 mL / min ntws ua tau txaus? Puas yog 15KPa siab txaus hauv kev siv tiag? Thiab qhov 100,000-cycle test tiag tiag txhais li cas rau cov khoom lag luam?
Kab lus no txiav los ntawm cov specs thiab muab rau koj cov tswv yim, daim ntawv thov-raws li kev qhia rau kev txiav txim siab.
3V vs . 6V – Qhov Voltage Fits Koj Qhov System?
Qhov no tsis yog hais txog "siab dua yog zoo dua."Koj qhov kev xaiv yog nyob ntawm tus tswv cuab lub zog architecture.
Thaum twg los xaiv 3V version
Yog tias koj lub cuab yeej khiav ntawm ib lub lithium ntawm tes lossis ob lub roj teeb alkaline, lub twj tso kua mis 3V yuav luag txhua qhov kev xaiv -tsis muaj boost converter xav tau.
Ntxiv ib theem boost nce BOM tus nqi thiab qhia txog kev poob pauv. Rau cov roj teeb-powered iav, txhua milliampere suav. Lub 3V version kos<200mA rated, but under intermittent duty the average current is much lower.
Qhov no ua rau nws ib txwm haum raukhoom siv kho mob portable(piv txwv li, condensate ntws hauv me me oxygen concentrators) thiabhandheld water quality testers.
Qhov zoo ntawm 6V version
Lub 6V twj tso kua mis muajefficiency ntau dua. Nyob rau tib lub zog tso zis, siab dua voltage txhais tau tias qis dua tam sim no - ceeb toom rau<150mA rating, 50mA less than the 3V model.
Tsawg tam sim no txhais tau tiastsawg cua sov tsim thiab qis kub nce. Qhov ntawd tseem ceeb rau cov khoom siv uas ua haujlwm tsis tu ncua lossis raug kaw hauv cov thawv kaw ntom ntom. Tsis tas li ntawd, yog tias koj lub cev twb muaj qhov ruaj khov 5V lossis 6V rail (piv txwv li, USB lub zog lossis plaub lub alkaline), 6V version zam kev hloov hluav taws xob ntxiv, ua kom yooj yim rau koj tus qauv tsim.
Cov kab hauv qab:mus 3V rau roj teeb lub hwj chim, mus 6V thaum koj muaj kev ruaj khov rail.
Flow Rate 40-60 mL / min - Puas yog txaus?
Engineers tshiab rau micro twj feem ntau xav tias: "Tsuas yog kaum milliliters ib feeb - qhov ntawd ua tau li cas?"
Nws nyob ntawm seb koj daim ntawv thov yog hais txog "hloov" lossis "metering."
Rau cov khoom siv portable, qhov kev khiav dej num no yog qhov ua tau zoo heev. Siv cov condensate tshem tawm hauv cov pa oxygen concentrator - dej tsim maj mam thiab xav tau kev txhim khu kev qha, tswj kev khiav tawm, tsis yog dej nrawm.
Ib yam li ntawd, hauvonline saib xyuas dej zoo, lub twj tso kua mis rub cov qauv me me mus rau hauv chav ntsuas ntsuas ntawm lub sijhawm teem sijhawm . 40-60 mL / min, ua ke nrog kev tswj xyuas kom meej / tawm, muab qhov sib npaug ntawm qhov tseeb ntawm qhov ntsuas qhov tseeb thiab lub raj xa dej.
Qhov kev khiav dej num no tseem ua rau cov tubing thiab cov khoom sib txuas sib txuas - qhov txiaj ntsig tiag tiag hauv cov qauv tsim me me uas cov dej ntws loj heev yuav xav tau cov khoom siv ntau dua.
Siab 15KPa - Dab tsi tuaj yeem nqa tau?
Cov ntsiab lus siab feem ntau to taub yuam kev. 15KPa sib npaug li 1.5 meters ntawm lub taub dej - tab sis qhov ntawd yogMaximum kaw-off siab(zero flow).
Hauv qhov system tiag tiag, lub twj tso kua mis yuav tsum kov yeej peb hom kev tiv thaiv:
Tube kev sib txhuam- Cov hlab nqaim thiab ntev dua ua rau muaj kev tiv thaiv.
Qhov siab sib txawv- nqa dej saum lub twj tso kua mis ntxiv lub taub hau zoo li qub.
End-device backpressure- lim, nozzles, los yog nplua orifices tsim ntxiv load.
15KPa muab cov npoo loj rau feem ntau cov tshuab nqa tau. Piv txwv li, nyob rau hauv lub tshuab kas fes los yog dej dispenser, lub twj tso kua mis nqa dej los ntawm lub tank mus rau lub rhaub - feem ntau tsawg dua 30cm qhov siab, nrog tubing hauv qab 1 meter. 15KPa ua haujlwm yooj yim.
Qhov tseem ceeb yog musdaim ntawv qhia koj tus kheej qhov kev tiv thaives tsis yog tsuas yog ntsia ntawm lub twj tso kua mis tus lej max. Thaum tsis ntseeg, kev sim lub rooj zaum nrawm nrog koj lub raj tiag tiag yog txoj hauv kev txhim khu kev qha tshaj plaws.
100,000-Cycle Life Test – Nws txhais li cas hauv kev xyaum
"100,000 cycles (5s on, 5s off)" qhia koj li cas?
Nws txhais tau tias lub twj tso kua mis tsim lub neej nyob rau hauvua haujlwm tsis tu ncua- 5 vib nas this khiav, 5 vib nas this tawm, rov ua dua 100,000 zaug. Uas sib npaug txog500,000 vib nas this ntawm lub sijhawm khiav, lossis kwv yees li 139 teev ntawm kev ua haujlwm tas mus li.
Txhais qhov ntawd nrog cov ntsiab lus. Rau cov khoom siv hauv tsev (piv txwv li, lub tshuab nqus tsev nqus dej lub tshuab nqus dej) uas ua haujlwm 10-15 zaug hauv ib hnub, 100,000 lub voj voog txhais ua ntau xyoo ntawm kev pabcuam - zoo kawg nkaus. Rau cov khoom siv ua haujlwm tsis tu ncua, koj yuav tsum ntsuas koj lub luag haujlwm lub luag haujlwm kom zoo dua.
Kuj tseem nco txog qhov kev xeem:5s rau / 5s tawm yog qhov xav tau heev- nquag pib thiab nres kev ntxhov siab ntawm lub diaphragm thiab valve. Dhau qhov kev xeem no qhia tias muaj zog qaug zog.
Lwm yam Specs tsim nyog ceeb toom
Suab nrov<65dB (at 30cm)- kwv yees li theem ntawm kev sib tham ib txwm. Rau kev kho mob thiab hauv tsev, qhov no feem ntau yog siv tau. Yog tias koj muaj suab nrov ntxiv, xav txog kev ntxiv roj hmab damping mounts lossis kho lub twj tso kua mis kev taw qhia kom txo qis resonance.
Kev khiav hauj lwm ib puag ncig 0-50 degree, 75% RH- npog feem ntau sab hauv tsev thiab tsheb xwm txheej. Qhov ntsuas ntsuas 75% txhais tau hais tias lub twj tso kua mis tuaj yeem ua haujlwm nyob rau hauv qhov chaw ntub dej, tab sis tsis txhob cuam tshuam ncaj qha rau ntawm lub cev muaj zog.
