Nthawi zambiri timamva za machubu oyendetsera ntchito, machubu odziwika bwino, machubu amadzimadzi, machubu ogwiritsira ntchito zida, machubu oyesera, machubu a twin ferrules, machubu osasinthika, machubu a BA, machubu ozungulira olondola, ndi zina zotero. Popeza pali mayina ambiri, kodi dzina lodziwika bwino ndi ndani? Tiyeni tifotokoze bwino machubu achitsulo chosapanga dzimbiri pansipa.
Kuti timvetse momwe machubu osapanga dzimbiri amatchulidwira ndi kugawidwa m'magulu, lingaliro loyamba komanso losokoneza kwambiri ndikufotokozera:chubundi chitoliro. Zonse ziwiri, mapaipi ndi mapaipi zikutanthauza chitoliro mu Chingerezi, ndipo palibe kumasulira kofanana kwa Chitchaina. Ndiye kusiyana kwake ndi kotani?
1. Choyamba, njira zoyimira ndi zosiyana: mapaipi amaimiridwa ndi mainchesi akunja ndi makulidwe a khoma, pomwe mapaipi amaimiridwa ndi mainchesi a nominal a NPS (nominal pipe size) ndi nambala ya makulidwe a khoma.
2. Miyezo yosiyana: Muyezo wa mapaipi ndi ASTM A269 ndi ASTM A213, pomwe muyezo wa mapaipi ndi ASTM A312.
3. Kulekerera kosiyanasiyana: Kulekerera kwa mapaipi ndi kochepa kuposa kwa mapaipi. Powerengera kuthamanga, mapaipi nthawi zambiri amatha kuyimira kuthamanga molondola (psi), pomwe mapaipi nthawi zambiri amaimiridwa ndi kuthamanga kwa PN.
4. Makhalidwe ake ndi osiyana: chubu chili mu mkhalidwe wotsekedwa, ndipo palibe chifukwa chogwiritsira ntchito chitolirocho, ndichifukwa chake chubucho chikhoza kupindika mwachindunji, pomwe chitolirocho chikufunika kulumikizidwa ndi chigongono.
5. Ntchito zosiyanasiyana: Chubu chili ndi mafotokozedwe osiyanasiyana, kotero chimagwiritsidwa ntchito kwambiri mu makina a zida, pomwe chitoliro chili ndi mafotokozedwe ochepa ndipo chimagwiritsidwa ntchito kwambiri mu makina amagetsi ndi njira zopangira mapaipi.
Kodi dzina loyenera la "chubu" ndi "chitoliro" ku China ndi liti? Tikukhulupirira kuti ndikoyenera kwambiri kufananiza ndi "chitoliro chopangira" ndi "chitoliro chopangira" motsatana. Kusiyana kumeneku kumachokera pakugwiritsa ntchito ndipo ndiko kusiyana kwakukulu pakati pa "chubu" ndi "chitoliro".
Mayina ena ndi osavuta kuwasiyanitsa:
1. Poganizira za kupanga, mapaipi olumikizidwa amatchedwa mapaipi olumikizidwa, pomwe mapaipi opangidwa ndi kugwedezeka kolondola ndi kujambulidwa kozizira amatchedwa mapaipi osalumikizana. Mapaipi osalumikizana ayenera kugawidwa m'magulu a mapaipi osalumikizana olunjika ndi mapaipi osalumikizana okonzedwa mozizira kutengera momwe amagwirira ntchito molondola komanso kujambulidwa kozizira.
2. Chubu cha BA, chubu cha EP, chubu chopangira asidi, ndi chubu chopukuta zimasiyanitsidwa kutengera momwe zilili pamwamba. Chubu cha BA chimatanthauza kuphimba kowala kwa chubu, chubu cha EP chimatanthauza kupukuta kwa electrochemical kwa chubu, chubu chopangira asidi chimatanthauza kuchotsa gawo la oxide kudzera mu kusuntha kwa asidi pambuyo poti chubucho chakonzedwa, chomwe ndi mkhalidwe woyambira wa chubucho, ndipo chubu chopukuta chimatanthauza kupukuta kwa makina pamwamba pa chubucho.
3. Ponena za mapaipi amadzimadzi ndi machubu, makamaka amatchedwa kuyima pa ngodya yogwiritsira ntchito.
4. Machubu oyezera ndi ofanana ndi machubu ogawa, ndipo ndi gulu la machubu ogawa zida. Machubu ogawa ndi machubu okhala ndi mainchesi ndi makulidwe a khoma omwe amayesedwa m'mayunitsi ogawa.
5. Chitoliro cha dzina kwenikweni ndi chitoliro, ndipo lingaliro la chitoliro cha dzina lingapezeke mu kufotokozera mwatsatanetsatane kwa lingaliro la dzina la Hikelok.
Hikelok, katswiri wopanga ma valve ndi zolumikizira zida.
Kuti mudziwe zambiri zokhudza kuyitanitsa, chonde onani zomwe mwasankhamakatalogupaWebusaiti yovomerezeka ya HikelokNgati muli ndi mafunso aliwonse okhudza kusankha, chonde funsani akatswiri ogulitsa pa intaneti a Hikelok omwe amagwira ntchito maola 24 pa intaneti.
