Ukuqhuma kwamapayipi

Amapayipi axhuma umhlaba wethu. Izicelo zabo ziyahlukahluka: njengamapayipi ezokuthutha emkhakheni wamandla, emkhakheni wezimboni, noma njengezinto zokwakha. Izembatho zanamuhla zivikela amapayipi ngokuqhubekayo ekugqwaleni, futhi ukulungiswa okusebenzayo kwendawo kubalulekile ukuze kuqinisekiswe ukusebenza okuphezulu kokunamathela.

Ukuqhuma kuyinqubo lapho izinhlayiya ezincane ze-angular noma eziyindilinga ziqhutshwa ku-substrate ngomoya ocindezelweyo, amasondo ajikelezayo anesivinini esiphezulu, noma amaphampu amanzi.Njengengxenye yenqubo yokuhlanza indawo, ukuqhunyiswa kwamapayipi kusetshenziselwa ukususa ukugqwala nokungcoliswa kanye nokudala ukuhwashala nokuhlanzeka okufanele kwendawo ukuze kuqhubeke ukwelashwa.Le nqubo isetshenziswa kakhulu ngoba iyasebenza, iyonga, futhi iyasheshauma kuqhathaniswa nezinqubo ezijwayelekile zokulungiswa kwendawo njengokuhlanza ngesandla kanye nokuhlanza i-asidi.

Ngokuqhunyiswa kwamapayipi, kunezinhlobo ezimbili eziyinhloko: ukuqhunyiswa kwangaphandle nokuqhuma kwangaphakathi.

Ukuqhunyiswa Kwepayipi Kwangaphandle

Enqubweni yokuqhuma kwangaphandle, indawo yepayipi ngokuvamile iqhunyiswa ngenkathi ithuthwa ngendlu yokuqhuma. Ukuqhumisa phezulu kwenziwa ngamasondo omshini wokuqhuma onamandla aphezulu asheshisa ama-abrasives anomthelela omkhulu ngokumelene nendawo yepayipi.Emishinini yokuqhuma kwamapayipi angaphandle, i-abrasive iqhutshwa ngama-centrifugal turbines. Inani lama-turbine omshini ngamunye lincike kusayizi wepayipi elizoqhunyiswa kanye nesivinini esidingekayo kule nqubo.

Ukuqhuma Kwepayipi Kwangaphakathi

Ingaphakathi lamapayipi akulula ukufinyelela kuwo ngenkathi ufuna izinga eliphezulu lokuhlanzeka kwendawo ngaphambi kokumbozwa. Lokhu kudinga izisetshenziswa ezisezingeni eliphezulu zokuqhunyiswa kwamapayipi angaphakathi.Enqubweni yokuqhuma kwangaphakathi,i-hose yokuqhuma ifakwe ithuluzi lepayipi, futhi ithuluzi lihoxiswa ukusuka komunye umkhawulo wepayipi kuya komunye. Kufanele kusetshenziswe ubuchwepheshe bokuqhuma okuphezulu, okufana nokugeleza kokuqhuma okungu-360° odongeni lwangaphakathi, okushiya iphethini yokuqhuma engaguquki ilungele noma yikuphi ukumbozwa.

Uma sikhuluma ngobuchwepheshe, okokusebenza kokuqhunyiswa kwamapayipi kwangaphakathi kuhlukaniswe ngemishini yokuqhuma komoya kanye nemishini yokuqhumisa amasondo. imishini yokuqhumisa umoya ikakhulukazi eyamapayipi amancane ububanzi obungaphansi kuka-700mm, futhi ingaqhumisa ukucutshungulwa kwezingcezu eziyi-8 ngesikhathi esisodwa ngamasistimu okubamba amapayipi okuzenzakalelayo. Umshini wokuqhumisa amasondo ikakhulukazi owamapayipi amakhulu anobubanzi obungaphezulu kuka-500mm, futhi ungaqhumisa kuphela ukuhlanza ucezu olulodwa ngesikhathi. Ngakho-ke sidinga ukukhetha imishini efanele yokuqhunyiswa kwamapayipi ngosayizi wamapayipi.

I-BSTEC inikeza ikhwalithi ephezulu yamathuluzi okuqhuma kwamapayipi angaphakathi ukumbozwa kosayizi wangaphakathi wamapayipi ukusuka ku-18mm kuya ku-900mm.
