Ungahlola Izindlu Zezinzwa Zobufakazi Bokuqhuma Imininingwane Yemikhiqizo Yesitholi Segesi Sevidiyo Yokulandela,

Ungafaka kuphi i-Gas Sensor Housing?

Ukuthi kufanele ufake kuphi i-housing ye-gas sensor kungancika kakhulu ohlotsheni lwegesi oluzotholakala,

imininingwane yesenzwa, kanye nezimo ezithile zendawo lapho isenzwa izosetshenziswa khona.

Noma kunjalo, kunezinye izinto ezijwayelekile okufanele uzicabangele uma ufaka izindlu zezinzwa zegesi:

1. Indawo Yokuba Khona Kwegesi:

Okungcono kakhulu, inzwa yegesi kufanele ibekwe ezindaweni lapho ukuvuza kwegesi kungenzeka khona kakhulu noma lapho

kulindeleke ukuthi iqongelelane. Isibonelo, njengoba i-propane inzima kunomoya, izinzwa ezithola i-propane

kufanele ibekwe phansi emhlabathini. Ngokuphambene nalokho, njengoba i-methane ilula kunomoya, izinzwa ze-methane

kufanele ibekwe eduze kophahla.

2. Umoya opholile:

Inzwa kufanele ibekwe endaweni enomoya omuhle ukuze igesi ifinyelele inzwa ngempumelelo.

3. Gwema Izithiyo:

Inzwa kufanele ifakwe endaweni engenazo izithiyo ukuqinisekisa ukuthi igesi iyakwazi ukuvimba

finyelela inzwa ngokukhululeka.

Imibuzo Evame Ukubuzwa

Q1: Yiziphi izinto ezivame ukusetshenziswa ezindlini zezinzwa zegesi futhi ngani?

A1: Izindlwana zezinzwa zegesi zivame ukwenziwa ngezinto eziqinile, ezihlala isikhathi eside, futhi ezimelana negesi

izindawo ezinzima lapho zivame ukufakwa khona.

Lezi zinto zingahluka kodwa ngokuvamile ziyizinhlobo ezahlukene zepulasitiki noma izinsimbi.

Isibonelo, ipulasitiki ye-ABS ivame ukusetshenziswa ngenxa yamandla ayo, ukumelana namakhemikhali, kanye nokungabizi kakhulu.

Ezindaweni ezidinga kakhulu, insimbi engagqwali noma ezinye izinhlobo zensimbi ezingagqwali zingasetshenziswa

ngenxa yokuqina kwazo kanye nekhono lokubekezelela amazinga okushisa aphezulu kanye nokucindezeleka.

Izinto ezikhethiwe zendlu kumele futhi zingabi nomthelela kugesi noma amagesi okuzotholakala kuwo

gwema ukuphazamiseka kokusebenza kwenzwa.

UMBUZO 2: Ukwakheka kokungena kwegesi kanye nendawo yokuphuma endlini kuthinta kanjani ukusebenza kwenzwa?

A2: Ukwakheka kwendawo yokungena neyokuphuma kwegesi endlini kubalulekile ekusebenzeni kwenzwa.

Zenzelwe ukuvumela igesi eqondiwe ukuthi ifinyelele inzwa kanye nanoma yimaphi amagesi angewona aqondiwe noma igesi esetshenzisiwe

amagesi okumele akhishwe. Uma umklamo ungemuhle kangako, ungase unciphise izinga lapho igesi ifinyelela khona inzwa,

ukwehlisa isikhathi sokuphendula, noma kungavumela ukuqongelela kwamagesi angahlosiwe, okungase kuholele ekungalungini

ukufundwa. Usayizi, ukuma, kanye nendawo yezindawo zokungena kanye nezindawo zokuphuma konke kuyizici ezingathinta ukusebenza kwenzwa.

Umbuzo 3: Yiziphi izinyathelo zokuvikela ezimweni zemvelo ezihlanganiswe endlini yezinzwa zegesi?

A3: Izindlu zezinzwa zegesi ngokuvamile zihlanganisa izindlela eziningana zokuvikela ezimweni zemvelo.

Lokhu kungafaka phakathi izivalo noma ama-gasket ukuvikela ekungeneni kothuli noma umswakama, izinto ezingamelani nokushisa noma ama-insulator

ukuvikela emazingeni okushisa aphezulu, kanye nokwakhiwa okuqinile ukuvikela ekulimaleni ngokomzimba.

Kwezinye izimo, indlu ingafaka nesivikelo ukuvikela inzwa kanye nezinto zayo zikagesi kuma-electromagnetic

ukuphazamiseka kwemvamisa yomsakazo (i-EMI) noma ukuphazamiseka kwemvamisa yomsakazo (i-RFI). Lezi zinyathelo zokuvikela zisiza ukuqinisekisa ukuthi inzwa

iyaqhubeka nokusebenza kahle ezindaweni nasezimweni ezahlukahlukene.

UMBUZO 4: Ukufakwa kwendlu yenzwa yegesi kuvame ukuphathwa kanjani?

A4: Ukufakwa kwendlu yesensa yegesi kuncike ekusetshenzisweni kwayo, kodwa ngokuvamile kuklanyelwe ukuba

iguquguquka futhi ivumelane nezimo ezahlukahlukene. Indlu ingase ihlanganise izici ezifana nezimbobo zezikulufo, ukufakwa

amabakaki, noma izikhala zokubopha okuneziphu ukuze kube lula ukunamathela ezindongeni, ophahleni, emishinini, noma kwezinye izakhiwo.

Ezinye izindlu zezinzwa zegesi zenzelwe ukuthi zithuthwe noma zibekwe kabusha kalula, okuvumela ukuthi zikwazi ukuthwalwa okwesikhashana noma ziphathwe kalula.

ukufakwa. Lapho ufaka inzwa, kubalulekile ukuqinisekisa ukuthi ukungena kwegesi kanye nendawo yokuphuma akuvimbekile

nokuthi inzwa ibekwe kahle ukuze kutholakale igesi.

Umbuzo 5: Kungani ukufinyelela okulula kokulungiswa nokulinganiswa kubalulekile ekwakhiweni kwezindlu zezinzwa zegesi?

A5: Ukugcinwa nokulinganiswa okuvamile kubalulekile ekuqinisekiseni ukuthi inzwa yegesi iyaqhubeka nokusebenza kahle

futhi unikeze ukufundwa okunembile. Ngokuhamba kwesikhathi, ukusebenza kwenzwa kungahamba, noma inzwa ingase ingcole noma

kungenjalo zidinga ukulungiswa. Ngakho-ke, ukwakheka kwendlu kuvame ukuvumela ukufinyelela kalula ku-sensor yale misebenzi.

Lokhu kungase kuhilele izembozo noma iminyango esuswayo, amachweba okufinyelela, noma ngisho nemiklamo ye-modular evumela inzwa ukuthi ibe lula

isusiwe futhi yashintshwa. Lokhu kuqinisekisa ukuthi inzwa ingagcinwa kalula, okuholela ekusebenzeni okungcono kwesikhathi eside

futhi kungenzeka kwandise impilo yenzwa.

Umbuzo 6: Yiziphi ezinye izinto okufanele uzicabangele uma ufaka izindlu zezinzwa zegesi ezindaweni ezingase ziqhume?

A6: Uma ufaka izinzwa zegesi ezindaweni ezingase ziqhume, indlu ingadinga ukuvikelwa ekuqhumeni noma

kuphephile ngokwemvelo. Lokhu ngokuvamile kuhilela ukwakheka okuqinile okungaqukatha ukuqhuma kwangaphakathi ngaphandle kokukuvumela

ukukhanyisa amagesi endaweni ezungezile. Kusho nokuthi izinto zikagesi ezihambisana nenzwa akumelwe

khiqiza izinhlansi noma eminye imithombo yokushisa, ngisho nangaphansi kwezimo zamaphutha. Indlu kufanele iqinisekiswe ukuthi ifanelekile

amazinga (njenge-ATEX eYurophu noma amazinga e-Class/Division e-US) ukukhombisa ukuthi aklanywe

futhi ihlolwe ukuthi isebenza ngokuphephile kulezi zimo. Njalo hlola imithethonqubo nezindinganiso ezifanele zesifunda sakho

kanye nemboni ukuqinisekisa ukufakwa nokuphepha okufanele.

Umbuzo 7: Yiziphi izinto ezibalulekile okufanele uzicabangele lapho ukhetha indawo yokufaka indlu yesensa yegesi?

A7: Uma ukhetha indawo yokufaka indlu yesensa yegesi, kunezici eziningana ezibalulekile okufanele uzicabangele.

Okokuqala, inzwa kufanele ibekwe ezindaweni lapho kungenzeka khona ukuvuza kwegesi noma lapho kulindeleke khona igesi

ukuqongelela. Isibonelo, kumagesi asinda kunomoya, inzwa kufanele ibekwe phansi emhlabathini, kuthi kumagesi alula,

eduze kophahla. Inzwa kufanele ibe sendaweni enomoya omuhle, kude nezithiyo, futhi iqhelelane nemithombo

ukushisa noma ukusha okungenzeka. Kubalulekile futhi ukugwema ukukubeka ezindaweni ezinomswakama ophezulu, izinto ezibolile, noma

izimo ezibucayi ngaphandle kokuthi indlu iklanyelwe ngqo ukumelana nalezi zici. Okokugcina, qiniseka ukuthi inzwa

ifakiwe lapho ingafinyeleleka khona kalula ukuze ilungiswe njalo futhi ilinganiswe.

Noma yimiphi eminye imibuzo mayelana nesicelo sokuvikela ukuqhuma kwegesi embonini ye-Petrochemical kanye nesevisi yangokwezifiso,

Sicela uzizwe ukhululekile ukuxhumana nathi nge-imeyilika@hengko.comnoma uthumele umbuzo njengefomu elilandelayo. Ngiyabonga!
