• ukuphathwa kakubi kweflange yombhobho (oko kukuthi, ukubhabhisa iflenge okanye umbhobho ngehamile xa umbhobho osecaleni kunye/okanye iqhoshana lombhobho lingalungelelaniswanga)
• izibophelelo zemibhobho ezingafakwanga kakuhle (umz. ubungakanani obungachanekanga, ukwakhiwa kwekhonkrithi).

Kufuneka isenzo

Abanini bempompo zekhonkrithi

Abanini bempompo zekhonkrithi kufuneka baqinisekise ukuba izinga loxinzelelo lwempompo yekhonkrithi alugqithisi lombhobho. Umzekelo, ukuba impompo ilinganiswe kwi-85 Bar yoxinzelelo lwekhonkrithi ngoko akwamkelekanga ukuba umbhobho wentsimbi utshintshwe ngombhobho werabha ngowona mgangatho uphezulu we-45 Bar. Abanini kufuneka kwakhona bathathe amanyathelo afanelekileyo okuqinisekisa ukuba iprogram yoqinisekiso lomgangatho iyalandelwa ngelixa ifakela i-end fittings ukwenzela ukuba ukungaphumeleli kokufakwa kokuphela kuthintelwe. Kulula ngokubanzi ukufumana isatifikethi kumthengisi wasekhaya xa kuthengwa izixhobo.

Ukuba umnini wempompo yekhonkrithi ungenisa amacandelo avela phesheya, kunokuba nzima ukufumana ulwazi oluthembekileyo kwinkqubo yokuvelisa. Oku kunjalo xa umthengisi waphesheya engaziwa okanye akukho phawu lomenzi. Abavelisi abanganyanisekanga nabo baye baziwa ngokukopa amagama abavelisi kunye neempawu zorhwebo, ngoko ke ukuphawulwa kweemveliso kukodwa akunakubonelela ngobungqina obaneleyo bokuba loo mveliso iyifanele injongo yayo.

Umnini wempompo yekhonkrithi ongenisa izixhobo ezivela phesheya kolwandle uthatha imisebenzi yomthengi ongaphandle phantsi kweUMthetho weMpilo noKhuseleko eMsebenzini ka-2011(WHS Act). Umrhwebi othenga kumazwe angaphandle kufuneka enze, okanye alungiselele ukuba uyenzile, naziphi na izibalo, uhlalutyo, uvavanyo, okanye uvavanyo lwezixhobo zokulawula umngcipheko wokhuseleko.

Ababoneleli bemibhobho kunye nemibhobho

Ababoneleli bemibhobho kunye nemibhobho enezifakelo zokugqibela kufuneka baqinisekise ukuba inkqubo yoqinisekiso lomgangatho iyalandelwa ngelixa kuhlonyelwa izifakelo zokugqibela kunye nokuba ulwazi kule nkqubo luyafumaneka kumthengi.

Ababoneleli kufuneka kwakhona banike imiyalelo ebhaliweyo kwiiparamitha zokusebenza zemveliso kunye neendlela zokuhlola eziza kusetyenziswa.

Ukuba umthengisi uqhoboshela izixhobo zokugqibela kwimibhobho okanye imibhobho, umthengisi uthatha imisebenzi yabavelisi phantsi koMthetho we-WHS ukongeza kuloo misebenzi yababoneleli.

Ukufaka izixhobo zokugqibela kwimibhobho

Izixhobo zokugqibela zifakwe kwi-hoses ye-rubber usebenzisa iindlela ezimbini, i-crimping kunye ne-swaging. Ngendlela ye-crimping, i-compressive forces isetyenziswe kwi-radially kwinxalenye yangaphandle (i-ferrule) yesiphelo esifanelekileyo kunye nesiqu sangaphakathi esifakwe ngaphakathi kwesiphelo se-hose. Ukufakwa kwesiphelo esikrunekileyo kunokuqondwa ngokucacileyo ngokuhambelana okucacileyo ngaphandle kwesilinganisi sesiphelo (jonga iFoto yesi-5). Ngendlela yokugungqa, ukufakwa kokugqibela kufakwe kwi-hose xa ukufakwa kwesiphelo kutyhalelwa ekupheleni kombhobho phantsi koxinzelelo lwe-hydraulic. Nangona kuya kubakho ukuphawulwa ekupheleni kokulungelelaniswa kwenkqubo yokwenziwa, ukufakwa kwesiphelo se-swaged akunanto ibonakalayo njengokufakwa kwesiphelo esikrunekileyo. Ifoto yesi-2 ngumzekelo wokufakwa kwesiphelo esijijekileyo esahlulwe ngokuyinxenye kumbhobho.

Nangona i-crimping kunye ne-swaging yahluke kakhulu, zombini iindlela zixhomekeke kakhulu ekusebenziseni amacandelo asemgangathweni okunyamezela okuchanekileyo kunye nokuqinisekisa inkqubo engqongqo yokuncamathisela ukufakwa kwesiphelo.

Abavelisi bombhobho baya kuqinisekisa kuphela ukuba ithumbu labo liyakwazi ukumelana noxinzelelo lwekhonkrithi oluchaziweyo xa iziphelo zemibhobho ekumgangatho ophezulu zifakelwe. Abanye abenzi bombhobho basebenza phantsi kwengcamango ye-aisibini esihambelanayoapho baya kuqinisekisa kuphela i-hose yabo yoxinzelelo oluphezulu, xa izixhobo zokugqibela ezivela kumvelisi othile usebenzisa i-crimping eqinisekisiweyo okanye indlela yokuswayiza isetyenziswa.

Xa udibanisa izixhobo zokugqibela kwimibhobho qinisekisa:

• ukuthotyelwa kwayo yonke imiqathango echazwe ngumbhobho kunye/okanye umenzi wokugqiba ukulinganisa
• i-hose material kunye nemilinganiselo ifanelekile ukupompa ikhonkrithi kunye nokulungelelaniswa kohlobo oluthile lokugqiba ukugqiba
• Ubungakanani beendawo zangaphandle kunye zangaphakathi zokufakela kufuneka zibe ngaphakathi konyamezelo oluchazwe ngumenzi wethumbu okanye umenzi wokulinganisa imilinganiselo yombhobho osetyenzisiweyo.
• indlela yokudibanisa ukuphela kokugqiba kufuneka ihambelane neenkcukacha zomenzi (ulwazi oluvela kumenzi we-hose lunokufuneka kwakhona).

Uvavanyo lwesiphelo esifanelekileyo yindlela enye yokunceda ukubonisa ingqibelelo yoqhagamshelo. Uvavanyo lobungqina bazo zonke izixhobo okanye uvavanyo olutshabalalisayo lweesampulu ziindlela ezinokusetyenziswa. Ukuba uvavanyo lobungqina luyenziwa, indlela yovavanyo kufuneka iqinisekise ukufakwa kunye nombhobho awonakaliswa.

Ukulandela ukuqhotyoshela ukufakwa kwesiphelo kwi-hose, ukufakwa kufuneka kumakishwe ngokusisigxina ngolwazi kwinombolo yebhetshi kunye nophawu lokuchongwa kwenkampani efakela isiphelo. Oku kuya kunceda ngokulandelelwa kunye nokuqinisekiswa kwenkqubo yendibano. Indlela yokumakisha akufanele ichaphazele kakubi ingqibelelo yendibano yombhobho.

Ukuba kukho amathandabuzo malunga nenqobo yokuvelisa okanye uvavanyo olunxulumene nokufakwa kwesiphelo, ingcebiso yomvelisi wesixhobo sokuqala (i-OEM) kufuneka ifunyanwe. Ukuba oku akufumaneki, kufuneka kufunyanwe ingcebiso yenjineli eqeqeshelwe ngokufanelekileyo.

Ulwazi olubhaliweyo malunga nendlela yokuncamathisela isiphelo kufuneka sigcinwe lishishini elincamathela isiphelo kwaye kufuneka lifumaneke xa liceliwe.
