nkhani

Chitoliro cha FRP ndi mtundu watsopano wa zinthu zophatikizika, njira yake yopangira imadalira kwambiri kuchuluka kwa utomoni wa ulusi wagalasi womwe umazungulira wosanjikiza ndi wosanjikiza malinga ndi njirayo, umapangidwa pambuyo pa kutentha kwambiri. Kapangidwe ka khoma la mapaipi a FRP ndi koyenera komanso kotsogola, komwe kungapereke gawo lonse kuzinthu monga ulusi wagalasi, utomoni ndi wothandizira wochiritsa, zomwe sizimangokwaniritsa mphamvu ndi kuuma komwe zimagwiritsidwa ntchito, komanso zimawonetsetsa kuti mapaipi a FRP ndi okhazikika komanso odalirika.

Makhalidwe aukadaulo

1. Njira yopangira yopitilira

Njira yopangira zinthu zozungulira nthawi zonse imagawidwa m'mitundu itatu: kupindika kouma, kupindika konyowa ndi kupindika pang'ono kouma malinga ndi momwe matrix a resin alili panthawi yopangira zinthu zozungulira. Kupindika kouma kumagwiritsa ntchito ulusi wa prepreg kapena tepi yomwe yakonzedwa kale, yomwe imatenthedwa pamakina opindika kuti ifewetsedwe kukhala madzi okhuthala kenako n’kukulungidwa pa nkhungu yapakati. Chinthu chachikulu chomwe chimagwiritsidwa ntchito popanga zinthu zozungulira ndichakuti imagwira ntchito bwino kwambiri ndipo liwiro lake lopindika limatha kufika 100-200m/min; kupindika konyowa ndiko kupindika mwachindunji mtolo wa ulusi (tepi yonga ulusi) pa mandrel pansi pa mphamvu yolamulira mutaviika mu guluu; Kupindika kouma kumafuna kuwonjezera zida zowumitsa kuti muchotse chosungunulira mu ulusi woviika ulusi utaviika mu nkhungu yapakati.

2.Internal kuchiritsa njira youmba

Njira yophikira mkati ndi njira yothandiza kwambiri yopangira zinthu zopangidwa ndi ulusi wopangidwa ndi thermosetting. Chidebe chachikulu chomwe chikufunika pa njira yophikira mkati ndi kapangidwe kozungulira kopanda kanthu, ndipo malekezero onse awiri apangidwa ndi chotchingira china kuti chithandize kugwetsa. Chitoliro chachitsulo chopanda kanthu chimayikidwa mkati mwa chidebe chachikulu, ndiko kuti, kutentha. Pa chubu chachikulu, malekezero amodzi a chubu chachikulu amatsekedwa, ndipo malekezero ena amatsegulidwa ngati cholowera nthunzi. Mabowo ang'onoang'ono amagawidwa pakhoma la chubu chachikulu. Mabowo ang'onoang'ono amagawidwa molingana m'magawo anayi kuchokera ku gawo la axial. Chidebe chachikulu chimatha kuzungulira shaft, chomwe chili chosavuta kuzunguliridwa.

3. Dongosolo lochotsa

Pofuna kuthana ndi zofooka zambiri za kugwetsa mapaipi ndi manja, mzere wamakono wopanga mapaipi achitsulo chagalasi wapanga njira yogwetsa yokha. Kapangidwe ka makina a dongosolo logwetsa kamakhala makamaka ndi chipangizo chogwetsa trolley, silinda yotseka, chogwirira chogwetsa stripping, ndodo yothandizira ndi makina opumira. Trolley yogwetsa imagwiritsidwa ntchito kulimbitsa nkhungu yapakati panthawi yozungulira, ndipo silinda imatsekedwa panthawi yogwetsa. Ndodo ya pistoni imabwezeretsedwa, mpira wachitsulo wokwezedwa kumbali yakumbuyo umayikidwa pansi, spindle imamasulidwa, kenako zogwirizira zogwetsa zimamaliza njira yogwetsa spindle kudzera mu mphamvu yogwetsa spindle ndi silinda, ndipo potsiriza zimatseka silinda ndi zogwirizira zogwetsa stripping. Lekanitsani thupi la chubu ndi nkhungu yapakati ndi zida zina kuti mumalize njira yogwetsa.

Ziyembekezo za chitukuko chamtsogolo

Malo ambiri ogwiritsira ntchito zinthu ndi malo akuluakulu amsika

Mapaipi a FRP ndi opangidwa bwino kwambiri ndipo amatha kukwaniritsa zosowa za ntchito m'magawo ambiri. Magawo omwe amagwiritsidwa ntchito nthawi zambiri ndi monga kupanga zombo, kupanga zida zaukadaulo wapamadzi, petrochemical, gasi wachilengedwe, mphamvu zamagetsi, madzi ndi ngalande, mphamvu ya nyukiliya, ndi zina zotero, ndipo kufunikira kwa msika ndi kwakukulu.
