ISICELO
Izintambo Ezitholakala Ngokusesidlangalaleni (PAS) BS 5308 ziklanywe
ukuthwala ukuxhumana nokulawula izimpawu ezihlukahlukene
izinhlobo zokufakwa ezihlanganisa imboni ye-petrochemical. I
amasignali angaba yi-analogue, idatha noma uhlobo lwezwi futhi avela ezinhlobonhlobo
yama-transducer afana nokucindezela, ukusondela noma umbhobho. Ingxenye 2
Izintambo zohlobo 1 ngokuvamile ziklanyelwe ukusetshenziswa endlini nangaphakathi
izindawo lapho ukuvikelwa komshini kungadingeki.
Ihlolelwa ukuvikeleka kwesignali okuthuthukisiwe.

Isingeniso se-BS 5308 Ingxenye 2 Uhlobo 1 Ikhebula le-PVC/IS/OS/PVC
I. Uhlolojikelele
I-BS 5308 Ingxenye 2 Uhlobo 1 Ikhebula le-PVC/IS/OS/PVC ikhebula elikhethekile elakhelwe izinhlelo zokusebenza ezithile emkhakheni wokuxhumana nokulawula ukudluliswa kwesignali. Yakhelwe ukuhlangabezana nezidingo zezinhlobo ezahlukene zokufaka, ngokugxila ngokukhethekile ekusetshenzisweni kwasendlini nasezindaweni lapho ukuvikelwa komshini kungeyona into eyinhloko ekhathazayo.
II. Isicelo
Ukudluliselwa Kwesiginali
Le ntambo yenzelwe ukuthwala izinhlobo ezahlukene zamasiginali, okuyi-analogue, idatha, namasignali ezwi. Lawa masignali angatholakala kuma-transducer ahlukahlukene njengezinzwa zokucindezela, izitholi eziseduze, namakrofoni. Isebenza njengendlela ethembekile yokudlulisa lezi zimpawu ezinhlelweni zokuxhumana nokulawula, iqinisekisa ukuxhumana okungenamthungo phakathi kwezingxenye ezahlukene.
Indoor and Low - Izindawo Zokuvikela
Ingxenye 2 yezintambo zohlobo 1 zenzelwe ikakhulukazi izinhlelo zokusebenza zasendlini. Lokhu kuhlanganisa ukusetshenziswa ezakhiweni zamahhovisi, izikhungo zezentengiselwano, nasezindaweni zezimboni zasendlini. Kulezi zindawo, ikhebula alivezwanga ekucindezelekeni komshini okunzima okungase kuvezwe ngaphandle noma izindawo ezinobungozi kakhulu. Iphinde ifanele izindawo lapho ukuvikelwa komshini kungeyona imfuneko enkulu, njengoba ngokuvamile ayibandakanyi imithelela ebalulekile yomzimba, imihuzuko, noma izici zangaphandle.
Ukuphepha Kwesiginali
Ikhebula liyahlolwa ngayodwana, okuthuthukisa ukuphepha kwesignali. Kumasethingi lapho ubuqotho bamasignali adluliswayo bubalulekile, njengakumanethiwekhi okuxhumana azwelayo noma amasistimu okulawula, lokhu kuhlola kusiza ukuvimbela ukuphazamiseka. Ngokuvikela amasignali emithonjeni yangaphandle kazibuthe, iqinisekisa ukuthi amasiginali e-analogue, idatha, noma yezwi adluliselwa ngokunembile futhi ngaphandle kokuhlanekezelwa.
III. Izici
I-Voltage elinganiselwe
Nge-voltage elinganiselwe ye-Uo/U: 300/500V, ikhebula lisebenza kahle - liguqulelwe kuhlelo olubanzi lwezinhlelo zokusebenza zikagesi ezihlobene nokuxhumana nokulawula ukudluliswa kwesignali. Lesi silinganiso samandla kagesi sinikeza ukuhlinzekwa kwamandla okuzinzile kumasignali esiwadluliselayo, okuvumela ukusebenza kahle kwamadivayisi axhunyiwe.
Ikalelwe izinga lokushisa
Ikhebuli inebanga lokushisa elilinganiselwe elihluka ngokuya ngesimo salo. Ekufakeni okuhleliwe, ingasebenza ngaphakathi kwezinga lokushisa elingu-40ºC kuya ku-+80ºC, kuyilapho ezimweni eziguquguqukayo, ububanzi busuka ku-0ºC ukuya ku-+50ºC. Lokhu kubekezelelwa kwezinga lokushisa okubanzi kuvumela ukuthi kusetshenziswe ezimweni zezulu ezihlukene zasendlini, kusukela ezindaweni zokugcina ezibandayo kuya emakamelweni eseva afudumele.
Irediyasi Yokugoba Encane
Ubuncane berediyasi yokugoba ye-6D iyisici esiphawulekayo. Le ndawo egobayo encane uma kuqhathaniswa ibonisa ukuthi intambo ingagotshwa ngokucijile uma iqhathaniswa nezinye izintambo ngaphandle kokudala umonakalo esakhiweni sayo sangaphakathi. Lokhu kunenzuzo ngesikhathi sokufakwa, njengoba kuvumela ukuguquguquka okukhulu ekuhambiseni ikhebula emakhoneni kanye nasezikhaleni eziqinile ekufakweni kwangaphakathi.
IV. Ukwakha
Umqhubi
Ezindaweni eziphambanayo - eziyingxenye ephakathi kuka-0.5mm² - 0.75mm², ikhebuli isebenzisa izikhondatha zethusi eziguquguqukayo Zekilasi 5. Lawa makhondatha anikeza ukuguquguquka okuhle kakhulu, okuzuzisa izinhlelo zokusebenza lapho ikhebula ingase idinge ukugotshwa noma ukuqondiswa ngaphakathi kwezikhala ezingaphakathi. Ezindaweni ezingu-1mm² nangaphezulu, kuqashwa amakhondaktha ethusi anemicu Yekilasi 2. Bahlinzeka nge-conductivity enhle namandla emishini, ukuqinisekisa ukudluliswa kwesignali okuphumelelayo.
Ukumatanisa
Ikhebula lihlanganisa amakhondaktha amabili avaleleke asonte ndawonye. Lolu hlelo lokumatanisa lusiza ekwehliseni i-crosstalk phakathi kwamakhondatha, okubalulekile ekugcineni ubuqotho bezimpawu ezidlulisiwe, ikakhulukazi ezinhlelweni zokusebenza lapho amasignali amaningi ephathwa ngesikhathi esisodwa.
I-Insulation
I-PVC (Polyvinyl Chloride) insulation isetshenziswa kule ntambo. I-PVC iyimpahla ebizayo - ephumelelayo futhi evame ukusetshenziswa ekufakeni ikhebula. Ihlinzeka ngezindawo ezinhle zokuvikela ugesi, ukuvimbela ukuvuza kukagesi nokuqinisekisa ukuthi amasignali adluliselwa ngaphandle kokuphazanyiswa.
Ukuhlola
Isikrini ngasinye kanye nesisonke esenziwe nge-Al/PET (Aluminium/Polyester Tape) sinikeza isivikelo ekuphazamisekeni kozibuthe. Ezindaweni ezingaphakathi endlini lapho kusengase kube khona imithombo yomsindo kazibuthe, njengamathuluzi kagesi noma izintambo, lokhu kuhlola kusiza ukugcina ikhwalithi yamasignali adluliswayo.
I-Drain Wire
Intambo yokudonsa yethusi ethayiwe isebenzela ukuhlakaza noma yiziphi izinkokhiso ze-electrostatic ezingakheka kukhebuli. Lokhu kusiza ekuthuthukiseni ukuphepha nokusebenza kwekhebuli ngokuvimbela izinkinga ezihlobene nezimo.
Umgodla
I-sheath yangaphandle yekhebula yenziwe nge-PVC, ehlinzeka ngesendlalelo esengeziwe sokuvikela ezingxenyeni zangaphakathi. Umbala we-sheath oluhlaza okwesibhakabhaka - omnyama awunikezi nje kuphela ikhebula ukubonakala okuhlukile kodwa futhi usiza ekuhlonzeni kalula phakathi nokufaka.
