Ukwakhiwa, ukusebenza kahle kanye nokuqina kwamayunithi okulawula izinga lokushisa (TCUs) kuthuthukise ukulawulwa kwenqubo kuyo yonke imboni yepulasitiki kusukela aqala ukusetshenziswa ngawo-1960.Ngenxa yokuthi ama-TCU ngokuvamile anokwethenjelwa futhi ahlukahlukene, avame ukuhambahamba kakhulu futhi axhunywe emithonjeni yamanzi ehlukene kanye nezinhlobonhlobo zokubumba kanye nemishini yokucubungula.Ngenxa yalokhu kuba khona kwesikhashana, ukukhathazeka kokuxazulula inkinga okuyinombolo yokuqala kwama-TCU ngokuvamile kubandakanya ukuvuza.
Ukuvuza kuvame ukuvela ngenxa yesinye sezimo ezilandelayo - izixhumi ezixegayo;ama-pump seal agugile noma ukwehluleka kwezimpawu;kanye nezinkinga zekhwalithi yamanzi.
Omunye wemithombo esobala kakhulu yokuvuza ukufakwa okuxekethile.Lokhu kungenzeka uma ama-nifold, amapayipi noma izifakelo zamapayipi zihlanganiswa futhi zixhunywa ku-TCU.Ukuvuza kungase kuthuthuke ngokuhamba kwesikhathi njengoba i-TCU ingena emijikelezweni yokushisisa nokupholisa.Ukwenza uxhumano olungavuzi, kuhle kakhulu:
• Hlola kokubili intambo yesilisa neyesifazane ukuze uthole noma yikuphi ukungcola noma umonakalo.
• Faka i-sealant oculweni lwesilisa, usebenzisa amagobolondo amathathu etheyiphu ye-Teflon (PTFE), bese usebenzisa isivalo se-liquid seplumber kusukela ochungechungeni lwesibili, ukuze intambo yokuqala eqoshiwe ibambe iqhaza ngokuhlanzekile.(Qaphela: ochungechungeni lwe-PVC, sebenzisa kuphela isivalo esiwuketshezi, njengoba inqwaba eyengeziwe ye-PTFE tape noma ama-sealants anamathisele angakwazi futhi abangele ukuqhekeka.)
• Khipha intambo yowesilisa entambo yesifazane ize iqine ngesandla.Maka umugqa onqamula kuzo zombili izindawo owesilisa/owesifazane ekuxhumekeni ukukhombisa indawo yokuhlala yokuqala.
• Qinisa ukuxhuma usebenzisa isikrufu esilungisekayo (hhayi isikrufu sepayipi), usebenzisa i-TFFT (ukuqinisa umunwe kanye namajika angu-1.5) noma isikrufu setorque, bese umaka ukuma kokugcina kokuqina endaweni eseduze.
