Yethula:
Uxhaxha olunzulu lwezinhlelo zendle ezingaphansi komhlaba zidlala indima ebalulekile ekugcineni impilo yomphakathi kanye nenhlanzeko.Phakathi kwezinhlobo ezihlukahlukene zamapayipi asetshenziswa kulezi zinhlelo, amapayipi ane-polyurethane-lined avele njengento emisha ephawulekayo.Le bhulogi ihlose ukuveza ukubaluleka, izinzuzo kanye nokusetshenziswa kwamapayipi afakwe umugqa we-polyurethane emkhakheni weindleumugqas.
Funda ngepayipi elifakwe nge-polyurethane:
Ipayipi elifakwe nge-polyurethane, ebizwa nangokuthi i-PU lined pipe, iyipayipi lensimbi elihlanganiswe ne-polyurethane ngenqubo yokukhiqiza ekhethekile.Ilayini inokumelana okuhle kakhulu nokuguga, ukugqwala kanye namakhemikhali, okuyenza ilungele ukuhambisa indle nezinye izinto ezigqwalayo.
Izinzuzo zamapayipi anemigqa ye-polyurethane:
1. Ukuqina okuthuthukisiwe: Uhlaka lwe-polyurethane luvimbela ukuguga nokudabuka kwamapayipi, okunweba kakhulu impilo yamapayipi akho.Imelana nokuguga okubangelwa ama-slurries esivinini esiphezulu, izinto eziqinile nezinye izinto ezigqwalayo ezivame ukutholakala emanzini angcolile.
2. Ukumelana nokugqwala: I-Polyurethane inokumelana okuhle kakhulu kwamakhemikhali nokumelana nokugqwala.Ukusetshenziswa kwayo njengolwelwesi lwangaphakathi kuqinisekisa ukuvikeleka kwesikhathi eside ezintweni ezibolayo ezivame ukuba khona ezindleleni zendle, njenge-hydrogen sulfide.
3. Ukugeleza okubushelelezi: Ingaphezulu elibushelelezi kakhulu le-polyurethane lining linciphisa ukungqubuzana futhi likhuthaze ukugeleza okuqhubekayo, okungaphazamiseki.Lokhu kunciphisa ukusetshenziswa kwamandla, ukwehla kwengcindezi kanye namandla okunqwabelana kwemfucumfucu, kuqinisekisa ukudluliswa kwamanzi angcolile okusebenzayo.
Izicelo zamapayipi anemigqa ye-polyurethane:
1. Izinhlelo zikamasipala zokuthuthwa kwendle: Amapayipi afakwe ulayini we-polyurethane asetshenziswa kakhulu ezinhlelweni zendle kamasipala ukuze kuthuthwe indle ngendlela efanele futhi kuncishiswe ukulungiswa.Ukumelana nokugqwala kwazo kanye nekhono lokumelana nesivinini soketshezi oluphakeme kuzenza zilungele ukuthuthwa kwamanzi angcolile ezindaweni zokuhlala, ezohwebo nezimboni.
2. Ukuhlanzwa kukadoti wasezimbonini: Amanzi angcolile ezimbonini ngokuvamile aqukethe izinto ezigugulekayo nezigqwalayo, ezibeka izinselele kungqalasizinda yamapayipi ekhona.Amapayipi anemigqa ye-polyurethane ahlinzeka ngesixazululo esinokwethenjelwa ngokuvikela ukuguguleka okubangelwa izinhlayiya eziqinile namakhemikhali aqala ukugqwala.
3. Ukusebenza Kwezimayini: Amapayipi anemigqa ye-polyurethane aya ngokuya esetshenziswa ekufakweni kwezimayini ngenxa yokumelana kwawo okuhle kakhulu nokugqoka.Baphatha kahle ukuthuthwa kwe-slurry, i-tailings kanye neminye imikhiqizo yezimayini ngenkathi benciphisa isikhathi sokuphumula ngenxa yokunakekelwa.
4. Imboni kawoyela negesi: Emkhakheni kawoyela negesi, amapayipi anemigqa ye-polyurethane asetshenziswa ezigabeni ezihlukahlukene njengokumba, ukumba izimayini nokucwengisiswa.Babonakale besebenza ngempumelelo ekuphatheni ama-abrasives, amakhemikhali abolayo, ngisho noketshezi olunezinga lokushisa eliphezulu.
Ekuphetheni:
Ipayipi le-polyurethane lined liye lashintsha umhlaba weipayipi elishiselwe, enikeza izinzuzo ezinjengokuqina, ukumelana nokugqwala kanye nezakhiwo zokugeleza ezithuthukisiwe.Ukusetshenziswa kwazo ezinhlelweni zikamasipala zendle, ukulahlwa kwemfucuza yezimboni, ukusebenza kwezimayini, kanye nemboni kawoyela negesi kufakazele ukuguquguquka kwazo nokuthembeka kwazo.Njengoba amazwe ezama ukugcina ingqalasizinda yokulawulwa kwemfucuza ephumelelayo, ukuhlanganiswa kwamapayipi ane-polyurethane-lined kuqinisekisa ukusimama kwesikhathi eside kanye nokusebenza kahle kwezindleko.
