Iinkqubo zombane zanamhlanje zixhomekeke kuqhagamshelo phakathi kwezixhobo ezahlukeneyo, iibhodi zeesekethe, kunye neeperipherals. Kungakhathaliseki ukuba ukuhambisa amandla okanye iimpawu zombane, iintambo zingumqolo wokuqhagamshelwa kweengcingo, okwenza zibe yinxalenye ebalulekileyo yazo zonke iinkqubo.
Nangona kunjalo, ukubaluleka kweebhatyi zekhebula (uluhlu lwangaphandle olujikelezayo kunye nokukhusela abaqhubi bangaphakathi) luhlala luncinci. Ukukhetha izinto ezifanelekileyo zebhatyi yekhebula kuyisigqibo esibalulekileyo kwi-cable design kunye nokuveliswa, ngakumbi xa isetyenziswe kwiindawo ezinzima. Ukuqonda ibhalansi phakathi kokusebenza koomatshini, ukuchasana nokusingqongileyo, ukuguquguquka, indleko, kunye nokuthotyelwa komgaqo kubalulekile ekwenzeni ukhetho olulumkileyo.
Kwintliziyo yejacket yekhebula yikhaka elikhuselayo kwaye liqinisekisa ubomi kunye nokuthembeka kwentambo yangaphakathi. Olu khuselo lukhusela ukufuma, iikhemikhali, imitha ye-UV, kunye noxinzelelo lomzimba olufana nokuqhawuka kunye nefuthe.
Izinto eziphathekayo zeebhatyi zentambo ukusuka kwiiplastiki ezilula ukuya kwiipolymers eziphambili, nganye ineempawu ezizodwa ukuhlangabezana neemfuno ezithile zokusingqongileyo kunye noomatshini. Inkqubo yokukhetha ibalulekile kuba izinto ezifanelekileyo ziqinisekisa ukusebenza kakuhle kunye nokukhuselwa phantsi kweemeko ezilindelekileyo zokusetyenziswa.
Akukho "ubungakanani obufanayo bulingana nayo yonke" isisombululo seebhatyi zentambo. Izinto ezikhethiweyo zinokwahluka kakhulu ngokuxhomekeke kwiimeko ezizodwa zesicelo.
Kukho izinto ezininzi ekufuneka ziqwalaselwe xa ukhetha imathiriyeli yebhatyi yentambo efanelekileyo.
1. IiMeko zokusiNgqongileyo
Ukumelana nemichiza yinto ebalulekileyo ekukhetheni iibhatyi zekhebula, njengoko iintambo zinokudibana namafutha, i-solvents, i-acids, okanye iziseko, kuxhomekeke kwisicelo sabo. Ijacket yekhebula ekhethiweyo kakuhle inokuthintela ukuthotywa okanye ukubola kwamacandelo ayo angaphantsi, ngaloo ndlela igcina ingqibelelo yekhebula ebomini bayo benkonzo. Ngokomzekelo, kwiindawo zoshishino apho ukuvezwa kweekhemikhali kuqhelekileyo, kubalulekile ukukhetha izinto ezinokumelana neemeko ezinzima ngolo hlobo. Apha, iikhemikhali ezithile apho ikhebula liya kuboniswa khona kufuneka zihlolwe, njengoko oku kugqiba imfuno yezinto ezikhethekileyo ezifana ne-fluoropolymers ukufezekisa ukuchasana kweekhemikhali.
Ukumelana nemozulu kunye nokukhanya kwelanga yenye into ebalulekileyo eqwalaselwayo, ngakumbi kwiintambo ezisetyenziswa ngaphandle. Ukuba sesichengeni selanga ixesha elide kunokuzenza buthathaka izinto zemveli, nto leyo ekhokelela ekubeni ibe brittle kunye nokusilela ekugqibeleni. Izixhobo ezenzelwe ukuxhathisa imitha ye-UV ziqinisekisa ukuba intambo ihlala isebenza kwaye ihlala ixesha elide nakwilanga elibukhali. Kwizicelo ezinjalo, izixhobo ezifanelekileyo yiCPE thermoplastics, CPE thermostats, okanye EPR thermostats. Ezinye izinto eziphucukileyo, ezifana ne-cross-linked polyethylene (XLPE), ziphuhliswe ukubonelela ukuxhathisa okuphuculweyo kwe-UV, ukuqinisekisa ubude obude bentambo kwizicelo zangaphandle.
Ukongezelela, kwiindawo apho umngcipheko womlilo uxhalabile, ukukhetha ijacket yekhebula enomlilo ovuthayo okanye ukucima umlilo kunokuba lukhetho olusindisa ubomi. Ezi zixhobo zenzelwe ukumisa ukusasazeka kwamadangatye, zongeza umaleko obalulekileyo wokhuseleko kwizicelo ezibalulekileyo. Ukuncipha komlilo, ukhetho oluhle kakhulu lubandakanyaI-PVCthermoplastics kunye neCPE thermoplastics. Ezo zinto zinokucothisa ukusasazeka kwamadangatye ngelixa zinciphisa ukukhutshwa kweegesi ezinetyhefu ngexesha lokutsha.
2. IiPropati zoomatshini
Ukuxhatshazwa kwe-abrasion, amandla empembelelo, kunye nokukwazi ukutyumza kwebhatyi yekhebula kukuchaphazela ngokuthe ngqo ukuqina kwe-polyurethane. Oku kubaluleke kakhulu kwizicelo apho intambo inqumla kumhlaba ocela umngeni okanye ifuna ukuphathwa rhoqo. Kwizicelo ezihamba phambili, ezinje ngerobhothi okanye koomatshini abaguqukayo, ukukhetha ibhatyi yekhebula eneempawu eziphezulu zoomatshini kunokunceda ukunqanda ukutshintshwa rhoqo kunye nokugcinwa. Ezona zinto zigqwesileyo zokunxiba ezikwaziyo ukumelana nezigqubuthelo zebhatyi ziquka i-polyurethane thermoplastics kunye neCPE thermoplastics.
3. Ukuqwalaselwa kobushushu
Uluhlu lweqondo lokushisa olusebenzayo lwempahla yebhatyi yekhebula ingaba ngumahluko phakathi kokuphumelela okanye ukungaphumeleli kwenkqubo. Izinto ezingenakukwazi ukumelana nomgangatho wokushisa osebenzayo kwindawo yazo ejoliswe kuyo zinokuthi zibe brittle kwiimeko ezibandayo okanye zithobe xa zibonakaliswe kumaqondo aphezulu. Oku kuthotywa kungaphazamisa ingqibelelo yekhebula kwaye kubangele ukungaphumeleli kokufakelwa kombane, okubangelwa ukuphazamiseka kokusebenza okanye ubungozi bokhuseleko.
Ngelixa iintambo ezininzi eziqhelekileyo zinokuhlelwa ukuya kuthi ga kwi-105°C, usetyenziso olukhethekileyo lwePVC lusenokufuna ukumelana nobushushu obuphezulu. Kumashishini afana neoli kunye negesi, izicelo ezikhethekileyo zifuna izixhobo, ezifana ne-ITT Cannon's SJS series materials, ezinokumelana namaqondo okushisa ukuya kwi-200 ° C. Kula maqondo obushushu aphezulu, izinto ezahlukeneyo zingadinga ukuqwalaselwa, kubandakanywa i-PVC kwicala le-thermoplastic kunye ne-CPE okanye i-EPR okanye i-CPR kwicala le-thermostat. Izinto ezinokuthi zisebenze kwiindawo ezinjalo ziyakwazi ukumelana nokushisa okuphezulu kwaye zixhathise ukuguga kwe-thermal, ziqinisekisa ukusebenza kwekhebula ngexesha.
Qwalasela imekobume yobushushu obuphezulu, njengendawo yokugrumba elunxwemeni. Kule ndawo yoxinzelelo oluphezulu, ubushushu obuphezulu, kuyimfuneko ukukhetha impahla yebhatyi yekhebula enokumelana nokushisa okugqithisileyo ngaphandle kokuthotywa okanye ukungaphumeleli. Ekugqibeleni, ukukhetha izinto ezifanelekileyo zebhatyi yekhebula kunokuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo ngelixa ukwandisa ubomi besixhobo.
4. Imfuneko yokuba bhetyebhetye
Ezinye izicelo zifuna ukuba iintambo zihlale zibhetyebhetye phantsi kokugoba okuphindaphindiweyo kunye neentshukumo zokujija. Le mfuno yokuguquguquka ayinciphisi imfuno yokuqina; ngoko ke, izixhobo kufuneka zikhethwe ngononophelo ukulungelelanisa ngokufanelekileyo ezi mfuno zimbini. Kwezi meko, izinto ezifana ne-thermoplastic elastomers (TPE) okanye i-polyurethane (PUR) zithandwa ngenxa yokuqina kwazo kunye nokomelela.
Iikheyibhile ezisetyenziswa kwimizi-mveliso ezenzekelayo, umzekelo, kufuneka ziguquguquke kakhulu ukulungiselela ukuhamba koomatshini abafana neerobhothi. Iirobhothi zeMesh ezisetyenziselwa imisebenzi efana nokuchola kunye nokubeka iinxalenye ngumzekelo obalaseleyo wale mfuno. Uyilo lwabo luvumela uluhlu lwentshukumo, ukubeka uxinzelelo oluqhubekayo kwiintambo, kudinga ukusetyenziswa kwezinto ezinokumelana nokugoba kunye nokuguqula ngaphandle kokunciphisa ukusebenza.
Emva kokuqwalasela iimeko zokusingqongileyo, iipropati zomatshini, iqondo lokushisa, kunye neemfuno zokuguquguquka, kubalulekile ukuba uqaphele ukuba ububanzi bangaphandle bekhebula buya kuhluka kunye nesixhobo ngasinye. Ukuze uhlale unobume bendalo, i-diameter yekhebula kufuneka ihlale ngaphakathi kokutywinwa kwe-backshell okanye i-attachment attachment.
