Amapayipi Ensimbi Anezindwangu Zenjoloba
Amapayipi ensimbi afakwe irabha aklanyelwe ukusetshenziswa ezinhlotsheni ezahlukene zokupompa ezihudulayo. Izicelo ezifana nokukhipha umshini wokugaya, amaphampu anomfutho ophezulu, imigqa emide yemisila, izicelo zephampu ye-slurry edinga amandla kanye namapayipi adonsela phansi. Uhlangothi ngalunye lune-flange eqinile yerabha evulcanized.
Ipayipi lensimbi elinomugqa werabha elimelana nokugqwala lenziwe ngepayipi lensimbi elivamile njengezinto zohlaka futhi lisetshenziswa ngezakhiwo ezinhle kakhulu zerabha elimelana nokugqwala, elimelana nokugqwala kanye nelimelana nokushisa njengengqimba yelayini. Lihlanganiswa ubuchwepheshe obukhethekile obune-glue esebenza kahle kakhulu. Lisetshenziswa kakhulu kwezensimbi, amandla kagesi, imboni yamakhemikhali, uphethiloli, amalahle, usimende nakwezinye izindawo zezimboni. Emsebenzini wezimayini, lisetshenziswa kabanzi ohlelweni lokudlulisa imisele yezimayini, ukugcwalisa emuva kwemayini yamalahle kanye namasimu esistimu yamapayipi ahlobene. Ikakhulukazi, ipayipi lifaneleka kakhulu ukudlulisa izinga lokushisa eliphakathi kuka--50°C kuya ku-+150°C, okulula ukuligqoka kanye nokugqwala. Singakhulisa ubukhulu bodonga ekhoneni lepayipi ngokuya ngesidingo sekhasimende, ngaleyo ndlela sandise impilo yesevisi. Okwamanje, impilo yesevisi yepayipi lensimbi elinomugqa werabha ingafinyelela eminyakeni eyi-15-40 iyonke. Ipayipi lingajikeleziswa cishe ngama-degree angama-90 ngemva kweminyaka eyi-6-8 yesevisi. Isikhathi ngasinye sokujikeleza singandisa impilo yokukhonza, ipayipi lensimbi lingafakwa irabha ngokuphindaphindiwe izikhathi ezintathu kuya kwezine, ngaleyo ndlela kunciphisa ukusetshenziswa kwezindleko esikhathini esizayo.
