Isingeniso ku-BS 5308 Ingxenye 2 Uhlobo 2 Ikhebula le-PVC/IS/OS/PVC/SWA/PVC
I. Ukubuka konke
Ikhebula le-BS 5308 Ingxenye 2 Uhlobo 2 le-PVC/IS/OS/PVC/SWA/PVC liwumkhiqizo obalulekile emkhakheni wokuxhumana kanye nokudluliselwa kwesignali yokulawula. Lakhelwe ukuhlangabezana nezidingo zezimo ezahlukahlukene zokufakwa, ikakhulukazi embonini yamakhemikhali, ngenkathi linikeza izici ezahlukahlukene zokusebenza okuthembekile.
II. Isicelo
Ukudluliswa Kwesignali
Le ntambo yenzelwe ukuthwala izinhlobo ezahlukene zezimpawu, okuhlanganisa i-analogue, idatha, kanye nezimpawu zezwi. Izimpawu ezivela kuma-transducer ahlukahlukene njengezinzwa zokucindezela, izitholi zokusondela, kanye nemakrofoni zingadluliselwa ngempumelelo. Lokhu kuguquguquka kwenza ifaneleke ezinhlelweni eziningi zokuxhumana nokulawula, okunikeza ukuxhumana okungenamthungo kumasethingi ahlukene obuchwepheshe.
Imboni Ye-Petrochemical Nangaphandle Kwayo
Embonini yamakhemikhali kaphethiloli, lapho ukuphepha nokusebenza kahle kubaluleke kakhulu, le ntambo idlala indima ebalulekile. Ingasetshenziswa ekufakweni okuhlukene ngaphakathi embonini ukuqinisekisa ukudluliswa kwesignali okuthembekile kwezinqubo ezibalulekile.
Izidingo Zokuvikelwa Kwemishini
Ingxenye 2 Izintambo zohlobo 2 zenzelwe ngqo izimo lapho kudingeka khona izinga elikhulu lokuvikelwa kwemishini. Lokhu kufaka phakathi ukufakwa kwangaphandle noma okuveziwe kanye nokungcwaba ngqo ekujuleni okufanele. Ezindaweni zangaphandle, ikhebula lingavezwa ezicini ezahlukahlukene zemvelo njengesimo sezulu, umthelela ongokwenyama, noma ukuguguleka. Ikhono lokumbelwa ngqo lenza lifaneleke ukufakwa ngaphansi komhlaba lapho kufanele libhekane nokucindezela komhlaba kanye nomonakalo ongaba khona ovela ezintweni ezingaphansi komhlaba.
Ukuphepha Kwesignali
Umklamo wekhebula ohlolwe ngamunye uthuthukisa ukuphepha kwesignali. Ezindaweni lapho ubuqotho besignali bubalulekile khona, njengasezinhlelweni zokulawula zezimboni noma kumanethiwekhi okuxhumana, lesi sici siqinisekisa ukuthi izimpawu ezidlulisiwe zivikelekile ekuphazamisekeni, okugcina ukunemba nokuthembeka kwedatha noma ukuxhumana.
III. Izici
I-Voltage Elinganisiwe
Njengoba i-voltage ekalwe nge-Uo/U: 300/500V, ikhebula lifaneleka kahle ezinhlelweni eziningi zikagesi ezivamile ezihlobene nokuxhumana kanye nokudluliswa kwesignali yokulawula. Lesi silinganiso se-voltage siyivumela ukuthi isebenze ngaphakathi kobubanzi obujwayelekile, inikeze ukunikezwa kwamandla okuzinzile kwezibonakaliso ezithwalayo.
Izinga Lokushisa Elilinganiselwe
Ikhebula linobubanzi bokushisa obulinganiselwe obuhlukahluka kuye ngesimo salo. Ekufakweni okuzinzile, lingasebenza ngaphakathi kobubanzi bokushisa obungu-40ºC kuya ku-+80ºC, kanti ezimweni eziguquguqukayo, ububanzi busukela ku-0ºC kuya ku-+50ºC. Lokhu kubekezelela amazinga okushisa okubanzi kwenza likwazi ukusetshenziswa ezimweni nasezindaweni ezihlukahlukene, kusukela ezimweni ezibandayo kakhulu kuya ezimweni ezishisayo kakhulu.
Irediyasi Encane Yokugoba
Irediyasi yokugoba encane engu-12D ichazwe kule ntambo. Lesi sici sibalulekile ngesikhathi sokufakwa njengoba sinquma ukuthi intambo ingagoba kangakanani ngaphandle kokulimaza isakhiwo sayo sangaphakathi. Sivumela ukuguquguquka ekuqondiseni intambo ngezindlela ezahlukene zokufaka.
IV. Ukwakhiwa
Umqhubi
Ezindaweni ezinqamulayo eziphakathi kuka-0.5mm² - 0.75mm², ikhebula lisebenzisa abaqhubi bethusi abaguquguqukayo be-Class 5. Laba baqhubi banikeza ukuguquguquka okuhle kakhulu, okuwusizo ekusetshenzisweni lapho ikhebula lingadinga ukugoba noma ukushukunyiswa. Ezindaweni ezingu-1mm² nangaphezulu, kusetshenziswa abaqhubi bethusi abaxhunyiwe be-Class 2. Laba bahlinzeka ngokuhambisa okuhle kanye namandla omshini, okuqinisekisa ukudluliselwa kwesignali okusebenzayo kanye nokuqina.
Ukuvikela
Ukufakwa kwe-PVC (Polyvinyl Chloride) okusetshenziswa kule ntambo kunikeza ukufakwa kwe-elekthronikhi. I-PVC iyinto engabizi kakhulu futhi esetshenziswa kakhulu ekufakweni kwe-elekthronikhi, esiza ekuvimbeleni ukuvuza kukagesi nokuqinisekisa ubuqotho bezimpawu ezidluliswayo.
Ukuhlola
Isikrini somuntu ngamunye nesonke esenziwe nge-Al/PET (Aluminium/Polyester Tape) sinikeza isivikelo ekuphazamisekeni kwe-electromagnetic. Lokhu kubalulekile ekugcineni ikhwalithi yezibonakaliso ezidlulisiwe, ikakhulukazi ezindaweni ezinemithombo engaba khona yomsindo we-electromagnetic.
Ucingo Lokukhipha Amanzi
Ucingo lokukhipha amanzi olufakwe ethini lusiza ekususeni noma yimaphi amashaji kagesi anganqwabelana ekhebulani. Lokhu kusiza ekuthuthukiseni ukuphepha nokusebenza kwekhebula ngokuvimbela izinkinga ezihlobene nokungasebenzi kahle.
Ijazi Langaphakathi, Izembatho Zempi, kanye Nesigqoko
Ijazi langaphakathi, elenziwe nge-PVC, linikeza ungqimba olwengeziwe lokuvikela izingxenye zangaphakathi zekhebula. I-SWA (Galvanized Steel Wire Armour) inikeza ukuvikelwa okunamandla kwemishini, ivikela ikhebula emandleni angaphandle njengokuchoboza, ukushaywa, noma ukuklwebheka. Igobolondo langaphandle, elenziwe nge-PVC, livikela kakhulu ikhebula futhi linombala wegobolondo oluhlaza okwesibhakabhaka nomnyama, okusiza ekubonakaleni kalula ngesikhathi sokufakwa.
Ekuphetheni, ikhebula le-BS 5308 Ingxenye 2 Uhlobo 2 lwe-PVC/IS/OS/PVC/SWA/PVC likhebula eliklanywe kahle elinenhlanganisela yezici ezenza lifanelekele izinhlelo zokusebenza ezahlukahlukene. Amandla alo okuphatha izinhlobo ezahlukene zezimpawu, ukumelana nezimo zemvelo ezahlukene, kanye nokunikeza ukuvikelwa kwemishini kanye nezibonakaliso kuyenza ibe ukukhetha okuthembekile ezimbonini ezifana nemboni ye-petrochemical kanye nasezinhlelweni ezahlukene zokuxhumana nokulawula.
