Ukuqhushumba kwemibhobho

Imibhobho idibanisa ihlabathi lethu. Izicelo zabo ziyahlukahlukana: njengemibhobho yezothutho kwicandelo lamandla, kwicandelo lezoshishino, okanye njengezinto zokwakha. Iingubo zanamhlanje zikhusela imibhobho ngokuzinzileyo kwi-corrosion, kwaye ukulungiswa okusebenzayo komphezulu kubalulekile ukuqinisekisa ukusebenza okuphezulu kokugquma.

Ukudubula yinkqubo apho amasuntswana amancinane angama-angular okanye angqukuva aqhutywa kwi-substrate ngomoya oxinanisiweyo, ngamavili ajikelezayo ngesantya esiphezulu soomatshini, okanye iimpompo zamanzi.Njengenxalenye yenkqubo yokucoca umphezulu, ukuqhuma kombhobho kusetyenziselwa ukususa i-rust kunye nokungcoliswa kunye nokudala uburhabaxa obufanelekileyo kunye nokucoceka ukwenzela unyango olongezelelweyo.Le nkqubo isetyenziswa ngokubanzi kuba iyasebenza, iyonga, kwaye iyakhawulezaxa kuthelekiswa neenkqubo eziqhelekileyo zokulungiswa kwendawo ezifana nokucoca ngesandla kunye nokucoca i-asidi.

Ukuqhushumba kombhobho, kukho iindidi ezimbini eziphambili: ukuqhuma kwangaphandle kunye nokuqhuma kwangaphakathi.

Ukuqhushumba kwemibhobho yangaphandle

Kwinkqubo yokuqhuma kwangaphandle, umphezulu wombhobho ngokuqhelekileyo uqhuma ngelixa uthuthwa nge-cabin yokuqhuma. Ukuqhushumba komphezulu kufezekiswa ngamavili anamandla aphezulu aqhumayo anyusa i-abrasives enempembelelo ephezulu kumphezulu wombhobho.Kumatshini wokuqhushumba kombhobho wangaphandle, i-abrasive iqhutywa ziiinjini ze-centrifugal. Inani lee-injini zomtshini ngamnye lixhomekeke kubungakanani bombhobho oza kuqhushumba kunye nesantya esifunekayo kwinkqubo.

Ukuqhushumba kwemibhobho yangaphakathi

Ingaphakathi lombhobho akulula ukufikelela kulo ngelixa ufuna inqanaba eliphezulu lokucoceka komphezulu ngaphambi kokugquma. Oku kufuna izixhobo zokuqhushumba kwemibhobho yangaphakathi ekumgangatho ophezulu.Kwinkqubo yangaphakathi yokuqhushumba,i-hose yokuqhuma ifakwe isixhobo sombhobho, kwaye isixhobo sihoxisiwe ukusuka kwelinye icala lombhobho ukuya kwelinye. Itekhnoloji yokuqhuma okuphezulu kufuneka isetyenziswe, njengokugqabhuka kwe-360 ° kwindonga yangaphakathi, ishiya ipateni yokuqhuma ehambelanayo ilungele nayiphi na isambatho.

Ukuthetha ngobuchwephesha, izixhobo zangaphakathi zokuqhushumba kombhobho zahlulwe zibe zizixhobo zokuqhushumba komoya kunye nezixhobo zokuqhushumba kwevili. Isixhobo sokuqhushumba komoya senzelwe imibhobho emincinci enobubanzi obungaphantsi kwe-700mm, kwaye ingaqhumisa ukusetyenzwa ngamaqhekeza esi-8 ngexesha elinye kunye neenkqubo zokuphatha imibhobho ezenzekelayo. Isixhobo sokuqhushumba kwevili senzelwe imibhobho emikhulu enobubanzi obungaphezulu kwe-500mm, kwaye inokuqhushumba kuphela ukucoca isiqwenga esinye ngexesha. Ngoko ke kufuneka sikhethe izixhobo ezifanelekileyo zokuqhushumba kombhobho ngokobungakanani bombhobho.

I-BSTEC ibonelela ngezixhobo ezikumgangatho ophezulu zangaphakathi zokuqhushumba kombhobho ubungakanani bangaphakathi bombhobho ukusuka kwi-18mm ukuya kwi-900mm.
