Iinkqubo zombane zanamhlanje zixhomekeke kunxibelelwano phakathi kwezixhobo ezahlukeneyo, iibhodi zesekethe, kunye nezixhobo ezisetyenziswa kwi-peripherals. Nokuba zidlulisela umbane okanye imiqondiso yombane, iintambo zingumqolo wonxibelelwano olunentambo, nto leyo ezenza zibe yinxalenye ebalulekileyo yazo zonke iinkqubo.
Nangona kunjalo, ukubaluleka kweejakethi zekhebula (umaleko ongaphandle ojikeleza kwaye ukhusela ii-conductors zangaphakathi) kudla ngokuthathelwa ingqalelo. Ukukhetha izinto ezifanelekileyo zejakethi yekhebula sisigqibo esibalulekileyo kuyilo lwekhebula kunye nokuveliswa kwalo, ingakumbi xa zisetyenziswa kwiindawo ezinzima. Ukuqonda ulungelelwano phakathi kokusebenza koomatshini, ukumelana nokusingqongileyo, ukuguquguquka, iindleko, kunye nokuthobela imithetho kubalulekile ekwenzeni ukhetho olulumkileyo.
Embindini wejakethi yentambo kukho ikhaka elikhusela kwaye liqinisekisa ubomi kunye nokuthembeka kwentambo yangaphakathi. Olu khuselo lukhusela kumswakama, iikhemikhali, imitha ye-UV, kunye noxinzelelo lomzimba olufana nokukrala kunye nempembelelo.
Izinto ezisetyenziswa kwiijakethi zekhebula ziqala kwiiplastiki ezilula ukuya kwiipolymers eziphambili, nganye ineempawu ezizodwa ukuhlangabezana neemfuno ezithile zokusingqongileyo nezoomatshini. Inkqubo yokukhetha ibalulekile kuba izinto ezifanelekileyo ziqinisekisa ukusebenza kakuhle kunye nokhuseleko phantsi kweemeko zokusetyenziswa ezilindelekileyo.
Akukho sisombululo "esifanela bonke" kwiijakethi zekhebula. Izinto ezikhethiweyo zinokwahluka kakhulu ngokuxhomekeke kwiimeko ezikhethekileyo zesicelo.
Kukho izinto ezininzi ekufuneka ziqwalaselwe xa ukhetha izinto ezifanelekileyo zejakethi yekhebula.
1. Iimeko zeNdalo
Ukumelana neekhemikhali yinto ebalulekileyo ekukhetheni iijakethi zekhebula, njengoko iintambo zinokudibana neeoyile, izinyibilikisi, iiasidi, okanye iziseko, kuxhomekeke ekusetyenzisweni kwazo. Ijakethi yekhebula ekhethwe kakuhle inokuthintela ukubola okanye ukubola kwezinto zayo ezingaphantsi, ngaloo ndlela igcina ukuthembeka kwentambo ubomi bayo bonke. Umzekelo, kwiindawo zoshishino apho ukuvezwa kweekhemikhali kuxhaphakile, kubalulekile ukukhetha izinto ezinokumelana neemeko ezinzima kangaka. Apha, iikhemikhali ezithile eziza kuvezwa kuzo intambo kufuneka zivavanywe, njengoko oku kumisela imfuneko yezinto ezikhethekileyo ezifana ne-fluoropolymers ukuze kufezekiswe ukuxhatshazwa kweekhemikhali okugqithisileyo.
Ukumelana nemozulu kunye nokukhanya kwelanga yenye into ebalulekileyo, ingakumbi kwiintambo ezisetyenziswa ngaphandle. Ukuvezwa ixesha elide elangeni kunokwenza buthathaka izixhobo zemveli, okukhokelela ekubeni zibuthuntu kwaye ekugqibeleni zingasebenzi. Izixhobo ezenzelwe ukumelana nemisebe ye-UV ziqinisekisa ukuba intambo ihlala isebenza kwaye ihlala ixesha elide nokuba ilanga likhanya kakhulu. Kwiinkqubo ezinjalo, izixhobo ezifanelekileyo zii-thermoplastics ze-CPE, ii-thermostats ze-CPE, okanye ii-thermostats ze-EPR. Ezinye izixhobo eziphambili, ezifana ne-polyethylene edibeneyo (I-XLPE), zenzelwe ukubonelela ngokumelana ne-UV okuphuculweyo, ukuqinisekisa ukuba intambo ihlala ixesha elide kwimisebenzi yangaphandle.
Ukongeza, kwiindawo apho umngcipheko womlilo uxhalabisayo, ukukhetha ijakethi yekhebula ethintela umlilo okanye ezicimayo kunokuba lukhetho olusindisa ubomi. Ezi zinto zenzelwe ukunqanda ukusasazeka kwamalangatye, zongeza umaleko obalulekileyo wokhuseleko kwizicelo ezibalulekileyo. Kwizinto ezithintela umlilo, ukhetho oluhle lubandakanyaI-PVCiithermoplastics kunye neethermoplastics zeCPE. Ezi zinto zinokucothisa ukusasazeka kwamalangatye ngelixa zinciphisa ukukhutshwa kweegesi ezinobuthi ngexesha lokutsha.
2. Iipropati zoomatshini
Ukumelana nokukrala, amandla okuchaphazeleka, kunye nokukwazi ukutyumza kwejakethi yentambo kuchaphazela ngokuthe ngqo ukuqina kwe-polyurethane. Oku kubaluleke kakhulu kwiindawo apho intambo idlula kumhlaba onzima okanye ifuna ukuphathwa rhoqo. Kwiindawo eziphathwayo kakhulu, njengakwiirobhothi okanye oomatshini abatshintshayo, ukukhetha ijakethi yentambo eneempawu zoomatshini eziphezulu kunokunceda ukuphepha ukutshintshwa rhoqo kunye nokugcinwa. Izinto ezingcono kakhulu ezingagugiyo zezigqubuthelo zejakethi ziquka i-polyurethane thermoplastics kunye ne-CPE thermoplastics.
3. Izinto eziqwalaselwayo ngamaqondo obushushu
Uluhlu lobushushu bokusebenza kwezinto zejakethi yekhebula lunokuba ngumahluko phakathi kokuphumelela okanye ukungaphumeleli kwenkqubo. Izinto ezingakwaziyo ukumelana nobushushu bokusebenza kwindawo ezijonge kuyo zinokuba buthathaka kwiimeko ezibandayo okanye ziwohloke xa zibekwe kumaqondo obushushu aphezulu. Oku konakala kunokubeka emngciphekweni ukuthembeka kwentambo kwaye kubangele ukungaphumeleli kokufakelwa kombane, okubangela ukuphazamiseka kokusebenza okanye iingozi zokhuseleko.
Nangona iintambo ezininzi ezisemgangathweni zinokulinganiswa ukuya kuthi ga kwi-105°C, izicelo zePVC ezikhethekileyo zinokufuna ukumelana namaqondo obushushu aphezulu. Kwimizi-mveliso efana neoyile negesi, izicelo ezikhethekileyo zifuna izixhobo, ezifana nezixhobo ze-ITT Cannon's SJS series, ezinokumelana namaqondo obushushu ukuya kuthi ga kwi-200°C. Kwala maqondo obushushu aphezulu, izixhobo ezahlukeneyo zinokufuna ukuqwalaselwa, kuquka iPVC kwicala le-thermoplastic kunye neCPE okanye i-EPR okanye i-CPR kwicala le-thermostat. Izixhobo ezinokusebenza kwiindawo ezinjalo zinokumelana namaqondo obushushu aphezulu kwaye zimelane nokuguga kobushushu, okuqinisekisa ukusebenza kwentambo ngokuhamba kwexesha.
Cinga ngeendawo ezinobushushu obuphezulu, njengezixhobo zokugrumba ezikwindawo engaselunxwemeni. Kwezi ndawo zinoxinzelelo oluphezulu, kuyimfuneko ukukhetha izinto zejakethi yekhebula ezinokumelana nobushushu obuphezulu ngaphandle kokuwohloka okanye ukungaphumeleli. Ekugqibeleni, ukukhetha izinto zejakethi yekhebula ezifanelekileyo kunokuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo ngelixa kwandisa ubomi bezixhobo.
4. Isidingo Sokuguquguquka
Ezinye izicelo zifuna ukuba iintambo zihlale ziguquguquka phantsi kokugoba nokujika okuphindaphindiweyo. Le mfuneko yokuguquguquka ayinciphisi mfuneko yokuqina; ke ngoko, izixhobo kufuneka zikhethwe ngononophelo ukuze zilungelelanise ngokufanelekileyo ezi mfuno zimbini. Kule meko, izixhobo ezifana ne-thermoplastic elastomers (TPE) okanye i-polyurethane (PUR) ziyathandwa ngenxa yokuqina kwazo nokuqina kwazo.
Iintambo ezisetyenziswa kwi-automation yemizi-mveliso, umzekelo, kufuneka zibe bhetyebhetye kakhulu ukuze zilungele ukuhamba koomatshini abanjengeerobhothi. Iirobhothi ze-mesh ezisetyenziselwa imisebenzi efana nokuchola nokubeka iindawo zingumzekelo ophambili wale mfuneko. Uyilo lwazo luvumela uluhlu lwentshukumo, lubeka uxinzelelo oluqhubekayo kwiintambo, nto leyo ebangela ukuba kusetyenziswe izinto ezinokumelana nokugoba nokujika ngaphandle kokuphazamisa ukusebenza.
Emva kokuqwalasela iimeko zokusingqongileyo, iimpawu zoomatshini, ubushushu, kunye neemfuno zokuguquguquka, kubalulekile ukuqaphela ukuba ububanzi bangaphandle bentambo buya kwahluka ngokwezinto ezisetyenziswayo. Ukuze ihlale inobuhlobo nokusingqongileyo, ububanzi bentambo kufuneka buhlale ngaphakathi kwemingcele yokutywina ye-backshell okanye i-connector attachment.
