Oxygen yog lub hauv paus tseem ceeb los tswj tib neeg lub neej kev ua ub no thiab ua lub luag haujlwm tseem ceeb hauv ntau yam kev kho mob thiab kev cawm thaum muaj xwm txheej ceev. Cov cuab yeej tsim cov pa oxygen yog cov khoom siv kho mob tseem ceeb. Kev kub siab viav vias adsorption (PSA) cov pa oxygen ntau lawm tau siv dav hauv cov khoom siv oxygen me me thiab nruab nrab vim nws qhov zoo ntawm kev siv hluav taws xob tsawg, tsis muaj kuab paug, thiab kev nqis peev tsawg. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub siab viav vias adsorption txoj kev yog: los ntawm qhov sib txawv ntawm adsorption yam ntxwv ntawm molecular sieves rau oxygen thiab nitrogen, nitrogen yog adsorbed nyob rau hauv cov xwm txheej pressurized cais oxygen; Nyob rau hauv qhov txo qis cov xwm txheej, nitrogen yog desorbed los kho cov adsorption kev ua tau zoo ntawm molecular sieve kom ua tiav oxygen thiab nitrogen sib cais. Feem ntau tam sim no lub siab viav vias adsorption oxygen cov cuab yeej tsim khoom loj loj thiab hnyav hnyav, uas tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev txav mus los hauv thaj teb lossis hauv tsheb. Portable siab viav vias adsorption oxygen generators xa mus rau cov khoom siv oxygen uas tuaj yeem nqa tau yooj yim, muaj lawv tus kheej lub zog, thiab hnyav hnyav. Txawm li cas los xij, muaj kev tshawb fawb me me hauv daim teb no hauv Suav teb, thiab cov kev tswj hwm uas twb muaj lawm feem ntau yog qhov loj me, qis hauv automation, thiab tsis muaj kev ruaj ntseg. Nyob rau hauv txoj kev tshawb no, ua ke nrog lub siab viav vias adsorption oxygen ntau lawm txheej txheem, ib tug tswj system haum rau portable siab viav vias adsorption oxygen generators tau tsim thiab tsim los muab kev pab cuam rau kev tshawb fawb ntxiv thiab kev siv ntawm portable oxygen generators.

Siab viav vias adsorption oxygen ntau lawm txheej txheem

Txhawm rau tsim kom muaj lub zog viav vias adsorption oxygen generator, txoj kev tshawb no tau ua ke nrog lub hauv paus ntsiab lus ntawm kev siv lub zog viav vias adsorption oxygen ntau lawm thiab thawj zaug txiav txim siab cov txheej txheem pib ntawm cov pa oxygen ntau lawm, raws li qhia hauv daim duab. Txhawm rau txo qhov ntim thiab qhov hnyav ntawm lub tshuab hluav taws xob oxygen portable, qhov kev sim no tau siv ob lub tsev tsim cov pa oxygen. Cov txheej txheem tsim cov pa oxygen ob lub tsev yog dav siv hauv cov khoom siv oxygen me me vim nws cov qauv yooj yim, kev saib xyuas yooj yim, thiab tus nqi qis. Los ntawm kev hloov pauv kev ua haujlwm ntawm ob lub adsorption yees, kev tsim cov pa oxygen tas mus li thiab ruaj khov tuaj yeem ua tiav, thaum txo qhov ntim thiab loj ntawm cov khoom siv. Txhawm rau ua kom cov pa oxygen ntau ntxiv thiab txo qis kev siv hluav taws xob, qhov kev sim no tsim thiab siv cov txheej txheem nrog cov txheej txheem sib npaug. Cov txheej txheem sib npaug ntxiv txhim kho cov pa oxygen ntau lawm thiab txo cov kev siv zog ntawm lub cev los ntawm kev ua kom zoo dua qhov sib txawv siab. Kev sib xyaw ua ke ntawm cov txheej txheem no tsis yog tsuas yog txhim kho kev ua haujlwm ntawm lub tshuab nqus tsev siab viav vias adsorption oxygen generator, tab sis kuj tseem tswj tau lub zog noj thiab ntim ntawm cov cuab yeej thaum ua kom lub purity ntawm oxygen.



Load tsav Circuit Court tsim
Lub luag haujlwm tseem ceeb ntawm lub portable PSA oxygen concentrator muaj xws li cua compressors thiab solenoid li qub. Los ntawm kev siv lub tshuab solenoid ua ke, qhov ntim thiab qhov hnyav ntawm cov pa oxygen concentrator tuaj yeem txo tau zoo thaum txhim kho kev ruaj ntseg ntawm lub cev. Txawm li cas los xij, txij li kev khiav hauj lwm voltage ntawm lub tshuab cua compressor thiab solenoid valve yog DC 12V, thaum lub zog khiav hauj lwm ntawm lub microcontroller yog DC 3.3V, nws yog ib qho nyuaj rau ncaj qha tsav cov loads. Yog li ntawd, lub teeb liab tso zis los ntawm microcontroller yog inverted los ntawm 74LVC04 inverter thiab amplified los ntawm ULN2003 Darlington raj los tsav lub lag luam ntawm cov cua compressor thiab solenoid valve.
ULN2003 yog ib qho kev ua tau zoo ntawm cov khoom siv hluav taws xob sib txuas nrog qhov kub thiab txias thiab kev kub siab ua haujlwm thiab muaj peev xwm thauj khoom. Nws koom ua ke lub freewheeling diode thiab tuaj yeem ncaj qha tsav cov loads tam sim no nrog rau cov relays. Kev tsav tsheb Circuit Court schematic ntawm huab cua compressor thiab solenoid valve yog qhia hauv daim duab.



Cua compressor tsav Circuit Court tsim
Lub tshuab cua compressor yog lub zog tseem ceeb ntawm lub tshuab hluav taws xob siab viav vias adsorption (PSA) oxygen generator. Nws cais cov pa oxygen los ntawm kev nqus cua ambient thiab nias nws kom xa mus rau hauv lub adsorption ntauwd, uas yog qhov txuas tseem ceeb hauv kev tsim cov pa oxygen. Txhawm rau kom ua tau raws li qhov yuav tsum tau ua haujlwm tau zoo thiab ruaj khov ntawm cov khoom siv nqa tau, qhov system no siv Thomas micro brushless DC compressor, uas muaj qhov zoo ntawm kev ua haujlwm du, ntws loj, tsis tshua muaj kev vibration, tsis tshua muaj suab nrov thiab siv zog tsawg, thiab tsim nyog rau daim ntawv thov scenario ntawm lub tshuab hluav taws xob oxygen.
Lub brushless DC lub cev muaj zog yuav tsum muaj lub zog tsav hluav taws xob los ua kom tiav cov hluav taws xob sib hloov kom ntseeg tau tias nws ua haujlwm li qub. Yog li ntawd, ib txheej ntawm lub cev muaj zog tsav circuits raws li JY01 tswj nti yog tsim. Lub hauv paus ntsiab lus yog qhia nyob rau hauv daim duab. Los ntawm kev tsim qauv zoo tshaj plaws, kev khiav hauj lwm ceev thiab kev ruaj ntseg ntawm lub tshuab cua compressor tuaj yeem raug tswj kom raug.
Circuit Design thiab Principple
JY01 yog tus tswj nti tshwj xeeb uas siv rau brushless DC motors, nrog rau cov haujlwm tseem ceeb hauv qab no:
Kev tswj ceev linear: kom ua tiav kev tswj xyuas lub cev muaj zog;
Ntau yam kev tiv thaiv kev tiv thaiv: suav nrog kev tiv thaiv overcurrent, kev tiv thaiv undervoltage thiab kev tiv thaiv luv luv los xyuas kom muaj kev ruaj ntseg hauv Circuit Court;

Lub voj voog tsav tsheb yog raws li JY01, thiab rotor txoj hauj lwm teeb liab (Ha, Hb, Hc) tau los ntawm Hall sensor, thiab cov nti tsim cov teeb liab tsav tsheb sib xws. SPWM teeb liab tso zis los ntawm JY01 tswj lub tsav tsheb module IR2021, yog li tsav lub teb nyhuv transistor (FET) ntawm sab sauv thiab sab caj npab. Lub teeb liab tsav tsheb tau muab faib ua cov cim taw qhia sab sauv thiab sab caj npab: lub caj npab sab sauv ntawm MA, MB, thiab MC sawv cev los ntawm AT, BT, thiab CT raws li, thiab cov cim caj npab qis yog sawv cev los ntawm AB, BB, thiab CB.

Hauv kev xaus
Nyob rau hauv txoj kab nrog cov txheej txheem ntawm kev sib cais cov pa oxygen ntau lawm, qhov kev tshawb fawb no tsim cov txheej txheem sib cais ntawm cov pa oxygen generator uas siv lub tshuab STM32F407 ib leeg-chip microcomputer ua lub hauv paus tswj chav tsev, thaum tseem tsim cov khoom siv peripheral tswj circuits thiab tswj algorithms. Tag nrho cov kev tswj teeb pom kev zoo ntawm kev ua tus neeg siv-phooj ywg, yooj yim rau kev khiav lag luam, ruaj khov, thiab tsis tshua muaj kev ntseeg siab, nrog rau kev sib raug zoo ntawm tib neeg-tshuab muaj peev xwm. Tus qauv ntawm lub tshuab hluav taws xob oxygen tsim nyob rau hauv kev tswj hwm no yog qhov me me thiab muaj qhov hnyav heev. Thaum cov pa tawm cov pa tawm mus txog 0.8 L / min, cov pa purity tuaj yeem ncav cuag li 93.2%, ua tiav cov qauv tsim ua ntej. Saib tom ntej, muaj cov phiaj xwm los tshawb nrhiav cov kev cai ntse ntawm cov txheej txheem tsim cov pa oxygen. Los ntawm kev kho qhov tsis xws luag xws li lub twj tso kua mis ceev, lub sij hawm permeation, thiab lub siab ntawm daim nyias nyias, cov pa tawm cov pa tawm thiab purity ntawm lub tshuab hluav taws xob oxygen tuaj yeem raug hloov kho raws li qhov kub thiab txias hloov pauv thiab khaws cia nyob rau theem tsis tu ncua.
