Chiyambi Chatsopano cha Pump Suction PID Products ((Zodzipangira zokha)
Chithunzi cha GQ-AEC2232bX-P
Kodi gasi ya VOC ndi chiyani?
VOC ndiye chidule cha ma volatile organic compounds. M'lingaliro wamba, VOC imatanthawuza kulamula kwa zinthu zosakhazikika za organic; Komabe, pankhani yachitetezo cha chilengedwe, imatanthawuza gulu lazinthu zosakhazikika zomwe zimagwira ntchito komanso zovulaza. Zigawo zazikulu za VOC zikuphatikizapo ma hydrocarbon, halogenated hydrocarbons, oxygen hydrocarbons, and nitrogen hydrocarbons, kuphatikizapo benzene series compounds, organic chlorides, fluorine series, organic ketones, amines, alcohols, ethers, esters, acids, ndi petroleum hydrocarbons. Ndipo gulu lazinthu zomwe zimawopseza kwambiri thanzi la munthu.
Zowopsa za gasi wa VOC ndi ziti?
Kodi njira zodziwira mpweya wa VOC ndi ziti?
Kodi mfundo ya PID detector ndi chiyani?
Kuzindikira kwa Photoionization (PID) kumagwiritsa ntchito cheza cha ultraviolet chopangidwa ndi ionization ya gasi wa inert ndi malo amagetsi othamanga kwambiri kuti ayanitse mamolekyu a gasi omwe amayesedwa. Poyesa mphamvu yamakono yomwe imapangidwa ndi mpweya wa ionized, kuchuluka kwa mpweya woyesedwa kumapezeka. Atazindikiridwa, ma ions amalumikizananso mu mpweya woyambirira ndi nthunzi, kupangitsa PID kukhala chowunikira chosawononga.
Sensor yodzipanga yokha ya PID
Wanzeru zochititsa chidwi magetsi
Moyo wautali
Kugwiritsa ntchito chipukuta misozi chanzeru kusangalatsa gawo lamagetsi, kukulitsa moyo wa masensa (moyo> zaka 3)
Zamakono zosindikizira zamakono
Kudalirika kwakukulu
Zenera losindikiza limatenga zinthu za magnesium fluoride zophatikizidwa ndi njira yatsopano yosindikizira, kupewa bwino kutayikira kwa gasi komanso kuwonetsetsa moyo wa sensor.
Mphete yosonkhanitsa gasi pawindo
Kuzindikira kwakukulu komanso kulondola kwabwino
Pali mphete yosonkhanitsira gasi pawindo la nyali ya UV, yomwe imapangitsa kuti ionization ya gasi ikhale yolondola komanso yodziwika bwino komanso yolondola.
Teflon zinthu
Kukana kwa dzimbiri ndi kukhazikika kwamphamvu
Ziwalo zomwe zimawunikiridwa ndi nyali za ultraviolet zonse zimapangidwa ndi zinthu za Teflon, zomwe zimakhala ndi mphamvu zolimbana ndi dzimbiri ndipo zimatha kuchedwetsa oxidation ndi ultraviolet ndi ozone.
Mapangidwe a chipinda chatsopano
Kudziyeretsa ndi kukonza kwaulere
Mtundu watsopano wa kamangidwe ka chipinda chokhala ndi mawonekedwe owonjezera otuluka mkati mwa sensa, yomwe imatha kuwomba ndikuyeretsa sensa, kuchepetsa dothi pa chubu la nyali ndikukwaniritsa sensa yaulere.
Chowunikira chapampu chopangidwira makamaka cha sensor yatsopano ya PID chimalola sensa kuti ikwaniritse bwino kwambiri, kupereka zotsatira zodziwika bwino komanso chidziwitso cha ogwiritsa ntchito.
Mulingo wa anti-corrosion umafika pa WF2 ndipo umatha kutengera chinyezi chambiri komanso malo opopera mchere wambiri (Kupopera mankhwala a fluorocarbon penti yotsutsa dzimbiri pachipolopolo)
Ubwino 1: Palibe ma alarm abodza pamatenthedwe apamwamba komanso chinyezi
Kuyeseraku kunayesa kuyesa koyerekeza pakati pa zowunikira zachikhalidwe za PID ndi zowunikira zapawiri za PID m'malo a chinyezi cha 55 ° C. Zitha kuwoneka kuti zowunikira zachikhalidwe za PID zimakhala ndi kusinthasintha kwakukulu kwa ndende m'derali ndipo nthawi zambiri zimakhala ndi ma alarm abodza. Ndipo chojambulira cha Anxin chokhala ndi sensa yapawiri PID sichisinthasintha ndipo ndi chokhazikika kwambiri.
Ubwino 2: Moyo wautali ndi kukonza kwaulere
Sensor yatsopano ya PID
kuwunika kophatikizana
Kusefera kwa masitepe ambiri
Dziwani sensor ya PID yokhala ndi moyo wazaka zopitilira 3 ndikusamalira mwaulere pa moyo wake
Kupambana kwakukulu kofanana ndi moyo wa masensa othandizira
Ubwino 3: Mapangidwe amtundu, kukhazikitsa kosavuta ndi kukonza
PID sensor module, imatha kutsegulidwa mwachangu ndikuphatikizidwa kuti ikonzedwe
Pampu ya modular, imamanga mwachangu ndikusintha
Gawo lililonse lakwanitsa kupanga ma modular, ndipo magawo onse omwe ali pachiwopsezo komanso ogwiritsidwa ntchito asinthidwa mwachangu komanso mosavuta.
Kuyesera koyerekeza, kufananiza apamwamba ndi otsika
Poyerekeza ndi mtundu wa PID sensor womwe sunatengedwe
Kuyerekeza kuyesa ndi mtundu wina wa zowunikira pamsika

Zokhudza mafunso omwe ali ndi zowunikira za PID?
Yankho: Chogulitsa chomwe chinayambika nthawi ino makamaka chimalowa m'malo mwa makina athu atsopano a PID, omwe asintha mawonekedwe a chipinda cha mpweya (kapangidwe kameneka) ndi magetsi. Mapangidwe apadera oyenda njira amatha kuchepetsa kuipitsidwa kwa kuwala ndikukwaniritsa kupukuta machubu a nyale aulere kudzera mu kusefa kwamagawo angapo. Chifukwa cha makina opangira magetsi opangira magetsi, kugwira ntchito kwapakatikati kumakhala kosavuta komanso kwanzeru, komanso kuzindikira kophatikizana ndi masensa apawiri kumakwaniritsa moyo wazaka zopitilira 3.
Yankho: Ntchito zazikulu za bokosi lamvula ndikuletsa madzi amvula ndi nthunzi ya mafakitale kuti asakhudze mwachindunji chowunikira. 2. Pewani kukhudzidwa kwa kutentha kwakukulu ndi malo a chinyezi pa zowunikira za PID. 3. Tsekani fumbi mumlengalenga ndikuchedwetsa moyo wa fyuluta. Kutengera zifukwa zomwe zili pamwambazi, tapanga bokosi losalowa mvula ngati muyezo. Inde, kuwonjezera bokosi lopanda mvula sikudzakhudza kwambiri nthawi yoyankhira gasi.
Yankho: Tiyenera kukumbukira kuti kukonzanso kwa zaka 3 kumatanthauza kuti sensa siyenera kusungidwa, ndipo fyulutayo ikufunikabe kusungidwa. Tikukulimbikitsani kuti nthawi yokonza fyuluta nthawi zambiri imakhala miyezi 6-12 (yofupikitsidwa mpaka miyezi 3 m'malo ovuta kwambiri).
Yankho: Popanda kugwiritsa ntchito masensa apawiri kuti azindikire molumikizana, sensa yathu yatsopano imatha kukwaniritsa moyo wazaka 2, chifukwa cha sensor yathu yatsopano ya PID (ukadaulo wovomerezeka, mfundo yayikulu imatha kuwoneka mu gawo lachiwiri). Njira yogwirira ntchito ya semiconductor + PID yodziwika bwino imatha kukhala ndi moyo wazaka zitatu popanda vuto lililonse.
Yankho: a. Isobutene ili ndi mphamvu yochepa ya ionization, yokhala ndi Io ya 9.24V. Itha kukhala ionized ndi nyali za UV pa 9.8eV, 10.6eV, kapena 11.7eV. b. Isobutene ndi kawopsedwe kakang'ono komanso mpweya wotentha. Monga gasi wowongolera, sizimawononga thanzi la munthu. c. Mtengo wotsika, wosavuta kupeza
Yankho: Sichidzawonongeka, koma kuchuluka kwa mpweya wa VOC kungapangitse mpweya wa VOC kumamatira pawindo ndi electrode kwa nthawi yochepa, zomwe zimapangitsa kuti sensa isayankhe kapena kuchepetsa kukhudzidwa. M`pofunika yomweyo kuyeretsa UV nyale ndi elekitirodi ndi methanol. Ngati pali kukhalapo kwa nthawi yayitali kwa mpweya wa VOC wopitilira 1000PPM pamalopo, kugwiritsa ntchito masensa a PID sikutsika mtengo ndipo masensa osabalalitsa amayenera kugwiritsidwa ntchito.
Yankho: Kusamvana kwakukulu komwe PID ikhoza kukwaniritsa ndi 0.1ppm isobutene, ndipo kachipangizo kabwino ka PID kumatha kukwaniritsa 10ppb isobutene.
Mphamvu ya kuwala kwa ultraviolet. Ngati kuwala kwa ultraviolet kuli kolimba, padzakhala mamolekyu ambiri a gasi omwe amatha kukhala ionized, ndipo chisankhocho chidzakhala bwino.
Malo owala a nyali ya ultraviolet ndi pamwamba pa electrode yosonkhanitsa. Dera lalikulu lowala komanso malo osonkhanitsira ma elekitirodi akulu mwachilengedwe amabweretsa kusamvana kwakukulu.
Mphamvu yosinthira ya preamplifier. Kuchepa kwa mphamvu yamagetsi ya preamplifier, kumachepetsa mphamvu yodziwikiratu. Ngati kukondera kwa amplifier ogwirira ntchito kuli kwakukulu, chizindikiro chofooka chothandiza chomwe chilipo chidzamizidwa kwathunthu mumsewu wapano, ndipo kusamvana kwabwino sikungachitike mwachilengedwe.
Ukhondo wa bolodi lozungulira. Mabwalo a analogi amagulitsidwa pama board ozungulira, ndipo ngati pali kutayikira kwakukulu pa board board, mafunde ofooka sangathe kusiyanitsa.
Kukula kwa kukana pakati pa panopa ndi magetsi. Sensa ya PID ndi gwero lamakono, ndipo zamakono zimatha kukulitsidwa ndikuyesedwa ngati voteji kudzera pa resistor. Ngati kukana kuli kochepa kwambiri, kusintha kochepa kwa magetsi sikungatheke mwachibadwa.
Kusintha kwa analog-to-digital converter ADC. Kukwera kwa ADC, kumachepetsa chizindikiro chamagetsi chomwe chingathetsedwa, komanso kusintha kwa PID.
