Chiyambi cha Zogulitsa Zatsopano za PID Suction Pump (Ma sensors odzipanga okha)
GQ-AEC2232bX-P
Kodi mpweya wa VOC ndi chiyani?
VOC ndi chidule cha mankhwala osinthika achilengedwe. Mwanjira yachibadwa, VOC imatanthauza mphamvu ya mankhwala osinthika achilengedwe; Komabe, ponena za kuteteza chilengedwe, imatanthauza gulu la mankhwala osinthika achilengedwe omwe amagwira ntchito komanso owopsa. Zigawo zazikulu za VOC zikuphatikizapo ma hydrocarbon, ma halogenated hydrocarbons, ma oxygen hydrocarbons, ndi ma nitrogen hydrocarbons, kuphatikizapo benzene series compounds, organic chlorides, fluorine series, organic ketones, amines, alcohols, ethers, esters, acids, ndi petroleum hydrocarbons. Ndi gulu la mankhwala omwe ali pachiwopsezo chachikulu pa thanzi la anthu.
Kodi zoopsa za mpweya wa VOC ndi ziti?
Kodi njira zodziwira mpweya wa VOC ndi ziti?
Kodi mfundo ya PID detector ndi iti?
Kuzindikira kwa Photoionization (PID) kumagwiritsa ntchito kuwala kwa ultraviolet komwe kumapangidwa ndi ionization ya mpweya wopanda mphamvu ndi mphamvu yamagetsi yapamwamba kuti ionize mamolekyu a mpweya womwe ukuyesedwa. Poyesa mphamvu yamagetsi yomwe imapangidwa ndi mpweya womwe uli ndi ayoni, kuchuluka kwa mpweya womwe ukuyesedwa kumapezeka. Pambuyo pozindikirika, ma ayoni amaphatikizananso kukhala mpweya woyambirira ndi nthunzi, zomwe zimapangitsa PID kukhala chowunikira chosawononga.
Sensa ya PID yodzipangira yokha
Mphamvu zamagetsi zolimbikitsa mwanzeru
Moyo wautali
Kugwiritsa ntchito mphamvu yanzeru kuti kusangalatse mphamvu yamagetsi, kukulitsa kwambiri moyo wa masensa (moyo woposa zaka 3)
Ukadaulo waposachedwa wotseka
Kudalirika kwambiri
Zenera lotsekera limagwiritsa ntchito zinthu za magnesium fluoride pamodzi ndi njira yatsopano yotsekera, zomwe zimathandiza kupewa kutulutsa mpweya wosowa komanso kuonetsetsa kuti sensayo ikukhala ndi moyo nthawi yayitali.
Mphete yosonkhanitsira mpweya pawindo
Kuzindikira kwambiri komanso kulondola bwino
Pali mphete yosonkhanitsira mpweya pawindo la nyali ya UV, zomwe zimapangitsa kuti ionization ya mpweya ikhale yolondola kwambiri komanso kuti kuizindikira kukhale kosavuta komanso kolondola.
Zinthu za Teflon
Kukana dzimbiri ndi kukhazikika kwamphamvu
Ziwalo zomwe zimaunikiridwa ndi nyali za ultraviolet zonse zimapangidwa ndi zinthu za Teflon, zomwe zimakhala ndi mphamvu yolimbana ndi dzimbiri ndipo zimatha kuchepetsa kutentha kwa dzuwa ndi ozoni.
Kapangidwe ka chipinda chatsopano
Wodziyeretsa komanso wosamalira yekha
Mtundu watsopano wa kapangidwe ka chipinda chokhala ndi kapangidwe ka njira yolumikizira madzi mkati mwa sensa, komwe kumatha kupukuta ndi kuyeretsa sensa mwachindunji, kuchepetsa dothi pa chubu cha nyali ndikupangitsa sensa kukhala yopanda kukonza.
Chowunikira chokokera mpweya chomwe chapangidwira makamaka sensa yatsopano ya PID chimalola sensa kupeza bwino kwambiri, kupereka zotsatira zabwino zozindikirika komanso chidziwitso chabwino cha ogwiritsa ntchito
Mlingo woletsa dzimbiri umafika pa WF2 ndipo ukhoza kusinthasintha kuti ugwirizane ndi malo osiyanasiyana okhala ndi chinyezi chambiri komanso malo opopera mchere wambiri (Kupopera utoto wa fluorocarbon woletsa dzimbiri pa chipolopolo)
Ubwino 1: Palibe ma alarm abodza m'malo otentha kwambiri komanso chinyezi
Kuyeseraku kunayerekeza kuyesa koyerekeza pakati pa zozindikira zachikhalidwe za PID ndi zozindikira zamitundu iwiri za PID pamalo otentha kwambiri a 55 ° C. Zitha kuwoneka kuti zozindikira zachikhalidwe za PID zimakhala ndi kusinthasintha kwakukulu kwa kuchuluka kwa zinthu m'malo awa ndipo zimatha kubweretsa ma alarm abodza. Ndipo chowunikira cha Anxin chamitundu iwiri cha PID sichisinthasintha kwenikweni ndipo chimakhala chokhazikika kwambiri.
Ubwino 2: Moyo wautali komanso wopanda kukonza
Sensa yatsopano ya PID
kuwunika kophatikizana
Kusefa kwa magawo ambiri
Pezani sensa ya PID yokhala ndi moyo wa zaka zoposa 3 komanso yopanda kuisamalira nthawi yonse ya moyo wake.
Kupambana kwakukulu kofanana ndi moyo wa masensa othandizira
Ubwino 3: Kapangidwe ka modular, kukhazikitsa ndi kukonza kosavuta
Gawo la sensor ya PID, limatha kutsegulidwa mwachangu ndikuchotsedwa kuti likonzedwe
Pampu yokhazikika, yolumikizidwa mwachangu ndikusinthidwa
Gawo lililonse lapangidwa mwaluso, ndipo ziwalo zonse zosalimba komanso zogwiritsidwa ntchito zasinthidwa mwachangu komanso mosavuta.
Kuyesera koyerekeza, kuyerekeza zapamwamba ndi zochepa
Kuyerekeza ndi mitundu ya sensa ya PID yomwe sinalandire chithandizo
Kuyesa koyerekeza ndi mtundu wina wa zozindikira zomwe zili pamsika

Ponena za mafunso okhudza zozindikira za PID?
Yankho: Chogulitsa chomwe chatulutsidwa nthawi ino makamaka chimalowa m'malo mwa sensa yaposachedwa ya PID ya kampani yathu, yomwe yasintha kapangidwe ka chipinda cha mpweya (kapangidwe ka njira yoyendera) ndi njira yoperekera magetsi. Kapangidwe ka njira yapadera yoyendera magetsi kangathe kuchepetsa kuipitsidwa kwa kuwala ndikupangitsa kuti machubu a nyali asamawonongeke kudzera mu kusefa kwa magawo ambiri. Chifukwa cha njira yoperekera magetsi yomangidwa mkati mwa sensa, kugwira ntchito kwakanthawi kumakhala kosalala komanso kwanzeru, ndipo kuzindikira pamodzi ndi masensa awiri kumakwaniritsa moyo wa zaka zoposa 3.
Yankho: Ntchito zazikulu za bokosi la mvula ndikuletsa madzi amvula ndi nthunzi ya mafakitale kuti zisakhudze mwachindunji chowunikira. 2. Kuletsa kukhudzidwa kwa malo otentha kwambiri ndi chinyezi pa zowunikira za PID. 3. Kutseka fumbi mumlengalenga ndikuchedwetsa nthawi yogwira ntchito ya fyuluta. Kutengera ndi zifukwa zomwe zili pamwambapa, takonza bokosi losagwa mvula monga muyezo. Zachidziwikire, kuwonjezera bokosi losagwa mvula sikudzakhudza kwambiri nthawi yoyankhira mpweya.
Yankho: Dziwani kuti zaka zitatu zokha popanda kukonza zikutanthauza kuti sensa sikufunika kusamalidwa, ndipo fyulutayo ikufunikabe kusamalidwa. Tikupangira kuti nthawi yosamalira fyuluta nthawi zambiri imakhala miyezi 6-12 (yofupikitsidwa kufika miyezi itatu m'malo ovuta).
Yankho: Popanda kugwiritsa ntchito masensa awiri kuti azindikire majoini, sensa yathu yatsopano imatha kukhala ndi moyo wa zaka ziwiri, chifukwa cha sensa yathu yatsopano ya PID (ukadaulo wokhala ndi patent, mfundo yayikulu ikuwoneka mu gawo lachiwiri). Njira yogwirira ntchito yozindikira majoini a semiconductor + PID imatha kukhala ndi moyo wa zaka zitatu popanda vuto lililonse.
Yankho: a. Isobutene ili ndi mphamvu yochepa ya ionization, yokhala ndi Io ya 9.24V. Ikhoza kuyikidwa ndi ma ionization ndi nyali za UV pa 9.8eV, 10.6eV, kapena 11.7eV. b. Isobutene ndi poizoni wochepa komanso mpweya wochepa kutentha kwa chipinda. Monga mpweya woyezera, siwowononga thanzi la anthu. c. Mtengo wotsika, wosavuta kupeza
Yankho: Sichidzawonongeka, koma kuchuluka kwa mpweya wa VOC kungapangitse mpweya wa VOC kumamatira pawindo ndi electrode kwa kanthawi kochepa, zomwe zimapangitsa kuti sensa isayankhe kapena kuchepetsa mphamvu ya kuwala. Ndikofunikira kuyeretsa nyali ya UV ndi electrode nthawi yomweyo ndi methanol. Ngati pali mpweya wa VOC wopitilira 1000PPM pamalopo, kugwiritsa ntchito masensa a PID sikotsika mtengo ndipo masensa a infrared osafalikira ayenera kugwiritsidwa ntchito.
Yankho: Chitsimikizo chachikulu chomwe PID ingakwaniritse ndi 0.1ppm isobutene, ndipo sensa yabwino kwambiri ya PID imatha kukwaniritsa 10ppb isobutene.
Mphamvu ya kuwala kwa ultraviolet. Ngati kuwala kwa ultraviolet kuli kolimba pang'ono, padzakhala mamolekyu ambiri a mpweya omwe angasinthidwe kukhala ayoni, ndipo kuwalako kudzakhala bwino mwachibadwa.
Malo owala a nyali ya ultraviolet ndi malo a pamwamba pa elekitirodi yosonkhanitsa. Malo owala kwambiri ndi malo a elekitirodi yosonkhanitsa mwachibadwa zimapangitsa kuti pakhale kuwala kwapamwamba.
Mphamvu yamagetsi ya preamplifier. Mphamvu yamagetsi ya preamplifier ikachepa, mphamvu yamagetsi yodziwika bwino imakhala yofooka. Ngati mphamvu yamagetsi ya bias ya operational amplifier ndi yayikulu, chizindikiro chofooka chamagetsi chidzamizidwa kwathunthu mu mphamvu yamagetsi ya offset, ndipo resolution yabwino singapezeke mwachibadwa.
Ukhondo wa bolodi la ma circuit. Ma circuit a analog amagulitsidwa pa ma circuit board, ndipo ngati pali kutayikira kwakukulu pa bolodi la ma circuit, ma currents ofooka sangadziwike.
Kukula kwa kukana pakati pa mphamvu yamagetsi ndi mphamvu yamagetsi. Sensa ya PID ndi gwero la mphamvu yamagetsi, ndipo mphamvu yamagetsi imatha kukulitsidwa ndikuyesedwa ngati mphamvu yamagetsi kudzera mu resistor. Ngati kukana kuli kochepa kwambiri, kusintha pang'ono kwa mphamvu yamagetsi sikungatheke mwachibadwa.
Kutsimikiza kwa chosinthira cha analog-to-digital ADC. Kutsimikiza kwa ADC kukakhala kwakukulu, chizindikiro chamagetsi chomwe chingathetsedwe chimakhala chochepa, komanso kutsimikiza kwa PID kumakhala bwino.
