Amashanyarazi mashya PID Ibicuruzwa Intangiriro Intangiriro （Kwiyubaka byikora）
GQ-AEC2232bX-P
Gazi ya VOC ni iki
VOC ni impfunyapfunyo y’ibinyabuzima bihindagurika. Mubisanzwe, VOC bivuga itegeko ryibinyabuzima bihindagurika; Nyamara, mubijyanye no kurengera ibidukikije, bivuga icyiciro cyibinyabuzima bihindagurika bikora kandi byangiza. Ibice nyamukuru bigize VOC birimo hydrocarbone, hydrocarbone ya halogene, hydrocarbone ya ogisijeni, na hydrocarbone ya azote, harimo ibice bya benzene, chloride organic, fluorine, ketone kama, amine, alcool, ethers, esters, acide, na hydrocarbone ya peteroli. Kandi icyiciro cyimvange kibangamiye cyane ubuzima bwabantu.
Ni izihe ngaruka za gaze ya VOC？
Nubuhe buryo bwo kumenya imyuka ya VOC?
Ni irihe hame rya detektori ya PID?
Gutahura amafoto (PID) bifashisha imirasire ya ultraviolet iterwa na ionisiyasi ya gaze ya inert n'umuriro w'amashanyarazi mwinshi kugirango ionize molekile ya gaze iri kugeragezwa. Mugupima ubukana bugezweho buterwa na gaze ioni, ubunini bwa gaze iri kugeragezwa burabonerwa. Nyuma yo kumenyekana, ion zisubirana muri gaze yumwuka numwuka, bigatuma PID idashobora kwangiza.
Kwikorera wenyine PID sensor
Ubwenge bushimishije amashanyarazi
Kuramba
Gukoresha indishyi zubwenge kugirango ushimishe umurima wamashanyarazi, wongerera cyane ubuzima bwa sensor (ubuzima> imyaka 3)
Ikoranabuhanga rigezweho
Kwizerwa cyane
Idirishya rifunga ibikoresho bya fluoride ya magnesium ihujwe nuburyo bushya bwo gufunga, birinda neza imyuka ya gaze idasanzwe kandi ikanakoresha igihe cya sensor.
Idirishya ryo gukusanya gaze
Ibyiyumvo bihanitse kandi byukuri
Hano hari impeta yo gukusanya gaze kumadirishya ya UV, ituma ionisiyasi ya gaz irushaho kuba myiza kandi ikamenya neza kandi neza.
Ibikoresho bya Teflon
Kurwanya ruswa no gushikama gukomeye
Ibice bimurikirwa n'amatara ya ultraviolet byose bikozwe mubikoresho bya Teflon, bifite imbaraga zo kurwanya ruswa kandi bishobora kugabanya umuvuduko wa okiside na ultraviolet na ozone.
Imiterere y'icyumba gishya
Kwisukura no kubungabunga wenyine
Ubwoko bushya bwimiterere yicyumba cyongeweho igishushanyo mbonera cyimbere imbere ya sensor, gishobora guhuha no guhanagura sensor, kugabanya neza umwanda uri kumatara yamatara no kugera kubikoresho byubusa
Igikoresho cyo kuvoma pompe cyateguwe byumwihariko kuri sensor nshya ya PID ituma sensor igera kubikorwa byiza, itanga ibisubizo byiza byo gutahura hamwe nuburambe bwiza bwabakoresha
Urwego rwo kurwanya ruswa rugera kuri WF2 kandi rushobora guhuza nubushyuhe butandukanye hamwe n’ibidukikije byangiza umunyu (Gutera irangi rya fluorocarbon ibikoresho birwanya ruswa ku gishishwa)
Ibyiza 1: Nta gutabaza kubeshya mubushyuhe bwo hejuru nubushuhe
Ubushakashatsi bwerekanye igereranya ryagereranijwe hagati yimashini gakondo ya PID hamwe na sensor ebyiri za PID zerekana ahantu h’ubushyuhe buri hejuru ya 55 ° C. Birashobora kugaragara ko ibyuma bya PID gakondo bifite ihindagurika ryinshi ryibidukikije muri ibi bidukikije kandi bikunze gutabaza ibinyoma. Kandi Anxin yapanze sensor ebyiri ya sensor ya PID ihindagurika cyane kandi irahagaze neza.
Inyungu 2: Kuramba no kubungabunga ubuntu
Rukuruzi rushya rwa PID
gukurikirana
Ibyiciro byinshi
Menya sensor ya PID ifite ubuzima burengeje imyaka 3 no kuyitaho kubuntu mubuzima bwayo
Iterambere rikomeye ryagereranywa nubuzima bwa sensor ya catalitiki
Inyungu ya 3: Igishushanyo mbonera, kwishyiriraho no kubungabunga
PID sensor module, irashobora gufungurwa byihuse no gusenywa kugirango ibungabunge
Pompe modular, byihuse gucomeka no gusimbuza
Buri module yageze kubishushanyo mbonera, kandi ibice byose byoroshye kandi bikoreshwa byasimbuwe vuba kandi byoroshye.
Kugereranya igereranya, kugereranya hejuru na hasi
Ugereranije nibidatunganijwe bitumijwe hanze ya PID sensor
Kugereranya kugereranya hamwe nikirangantego runaka cya detector kumasoko

Kubyerekeye ibibazo hamwe na detektori ya PID?
Igisubizo: Igicuruzwa cyatangijwe kuriyi nshuro cyane cyane gisimbuza sosiyete yacu ya PID sensor igezweho, yahinduye imiterere yicyumba cyikirere (igishushanyo mbonera cyumuyoboro) nuburyo bwo gutanga amashanyarazi. Igishushanyo kidasanzwe cyumuyoboro urashobora kugabanya umwanda wumucyo no kugera kuhanagura itara ryubusa binyuze mumashanyarazi menshi. Bitewe nuburyo bwubatswe bwigihe gito bwo gutanga amashanyarazi ya sensor, imikorere yigihe gito iroroshye kandi ifite ubwenge, kandi guhuriza hamwe hamwe hamwe na sensor ebyiri bigera kumyaka irenga 3.
Igisubizo: Ibikorwa byingenzi bigize agasanduku k’imvura ni ukurinda amazi yimvura hamwe ninganda zikora inganda zitagira ingaruka kuri detector. 2. Irinde ingaruka zubushyuhe bwo hejuru nubushuhe bwibidukikije kuri deteri ya PID. 3. Funga umukungugu mukirere kandi utinde igihe cyo kuyungurura. Dushingiye ku mpamvu zavuzwe haruguru, twashyizeho agasanduku kitagira imvura nkibisanzwe. Nibyo, kongeramo agasanduku kitagira imvura ntabwo bizagira ingaruka zikomeye mugihe cyo gusubiza gaze.
Igisubizo: Twakwibutsa ko imyaka 3 yo kubungabunga kubuntu bivuze ko sensor idakeneye kubungabungwa, kandi akayunguruzo karacyakomeza kubungabungwa. Turasaba ko igihe cyo kubungabunga akayunguruzo ari amezi 6-12 (kigufi kugeza kumezi 3 ahantu habi ibidukikije)
Igisubizo: Hatabayeho gukoresha ibyuma bibiri kugirango tumenye hamwe, sensor yacu nshya irashobora kugera kubuzima bwimyaka 2, tubikesha sensor nshya ya PID ikora (tekinoroji yemewe, ihame rusange rirashobora kugaragara mugice cya kabiri). Uburyo bwakazi bwa semiconductor + PID ihuriweho hamwe irashobora kugera kubuzima bwimyaka 3 ntakibazo.
Igisubizo: a. Isobutene ifite ingufu nkeya ionisiyoneri, hamwe na Io ya 9.24V. Irashobora gutondekwa n'amatara ya UV kuri 9.8eV, 10.6eV, cyangwa 11.7eV. b. Isobutene ni uburozi buke na gaze mubushyuhe bwicyumba. Nka gaze ya kalibrasi, ntacyo yangiza kubuzima bwabantu. c. Igiciro gito, byoroshye kubona
Igisubizo: Ntabwo bizangirika, ariko ubwinshi bwa gaze ya VOC irashobora gutuma gaze ya VOC ifata idirishya na electrode mugihe gito, bikaviramo sensor kutitabira cyangwa kugabanya sensibilité. Birakenewe guhita usukura itara rya UV na electrode hamwe na methanol. Niba hari igihe kirekire cya gaze ya VOC irenga 1000PPM kurubuga, gukoresha sensor ya PID ntabwo bihenze kandi hagomba gukoreshwa ibyuma bifata ibyuma bitagabanije.
Igisubizo: Icyemezo rusange PID ishobora kugeraho ni 0.1ppm isobutene, kandi sensor nziza ya PID irashobora kugera kuri 10ppb isobutene.
Ubukomezi bwurumuri ultraviolet. Niba urumuri ultraviolet rukomeye cyane, hazaba molekile nyinshi za gaze zishobora kuba ionisiyoneri, kandi mubisanzwe bizaba byiza.
Agace kamurika k'itara rya ultraviolet hamwe n'ubuso bwa electrode ikusanya. Umwanya munini wumucyo hamwe nigice kinini cyo gukusanya electrode isanzwe itanga ibisubizo bihanitse.
Umuyoboro wa offset ya preamplifier. Gutoya ya offset ya progaramu ya preamplifier, intege nke zigaragara. Niba kubogama kwimikorere ya amplifier ikora ari nini, ibimenyetso byingirakamaro byingirakamaro bizarengerwa rwose muri offset ya none, kandi gukemura neza ntibishobora kugerwaho muburyo busanzwe.
Isuku yinama yumuzunguruko. Inzira zisa nizigurishwa ku mbaho zumuzunguruko, kandi niba hari ikintu kinini cyatembye ku kibaho cyumuzunguruko, imiyoboro idakomeye ntishobora gutandukanywa.
Ubunini bwurwanya hagati yubu na voltage. PID sensor ni isoko iriho, kandi ikigezweho gishobora kongerwaho gusa no gupimwa nka voltage binyuze mumurwanya. Niba kurwanya ari bito cyane, impinduka ntoya ya voltage ntishobora kugerwaho muburyo busanzwe.
Igisubizo cya analog-to-digitale ihindura ADC. Iyo hejuru ya ADC imyanzuro, ibimenyetso bito byamashanyarazi bishobora gukemurwa, kandi nibyiza bya PID.
