Kugwira ntchito kwa makina amadzimadzi am'mafakitale kumadalira kuyanjana kwa gawo lililonse lomwe limapereka njira yanu yamadzimadzi komwe ikupita. Chitetezo ndi zokolola za mbewu yanu zimadalira kutayikira kwaulere kugwirizana pakati pa zigawo zikuluzikulu. Kuti mudziwe kuyenera kwa makina anu amadzimadzi, choyamba mvetsetsani ndikuzindikira kukula kwa ulusi ndi mamvekedwe ake.

Ngakhale akatswiri odziwa zambiri nthawi zina zimawavuta kuzindikira ulusi. Ndikofunikira kumvetsetsa ulusi wamba ndi mawu othetsa ndi milingo kuti zithandizire kugawa ulusi wina.
Mtundu wa ulusi: ulusi wakunja ndi ulusi wamkati umatanthawuza malo a ulusi pa olowa. Ulusi wakunja umatuluka kunja kwa mgwirizano, pamene ulusi wamkati uli mkati mwa mgwirizano. Ulusi wakunja umalowetsedwa mu ulusi wamkati.
Phokoso: phula ndi mtunda pakati pa ulusi. Kuzindikiritsa machulukidwe kumatengera milingo ya ulusi, monga NPT, ISO, BSPT, ndi zina zotero. Pitch imatha kufotokozedwa mu ulusi pa inchi ndi mamilimita.
Addendum ndi dedendum: pali nsonga ndi zigwa mu ulusi, zomwe zimatchedwa addendum ndi dedendum motsatira. Pamalo athyathyathya pakati pa nsonga ndi muzu amatchedwa mbali.
Dziwani mtundu wa ulusi
Gawo loyamba lozindikira kukula kwa ulusi ndi phula ndi kukhala ndi zida zoyenera, kuphatikiza vernier caliper, pitch gauge ndi chizindikiritso cha phula. Agwiritseni ntchito kuti muwone ngati ulusiwo ndi wopendekera kapena wowongoka. tapered-thread-vs-wolunjika-chithunzi-chithunzi
Ulusi wowongoka (womwe umatchedwanso ulusi wofanana kapena ulusi wamakina) sugwiritsidwa ntchito kusindikiza, koma umagwiritsidwa ntchito kukonza nati pa thupi la cholumikizira cha casing. Ayenera kudalira zinthu zina kuti apange zisindikizo zotsikira, mongagaskets, O-mphete, kapena zitsulo kukhudzana zitsulo.
Ulusi wa tapered (womwe umadziwikanso kuti ulusi wosinthasintha) ukhoza kusindikizidwa pamene mbali za dzino za kunja ndi zamkati zimakokedwa pamodzi. M'pofunika kugwiritsa ntchito ulusi sealant kapena ulusi tepi kudzaza kusiyana pakati pa dzino nsonga ndi dzino muzu kuteteza kutayikira kwa dongosolo madzimadzi pa olowa.
Ulusi wa taper uli pa ngodya ku mzere wapakati, pamene ulusi wofananawo umafanana ndi mzere wapakati. Gwiritsani ntchito vernier caliper kuyeza nsonga kuti mupendekeke pakati pa ulusi wakunja kapena ulusi wamkati pa ulusi wonse woyamba, wachinayi komanso womaliza. Ngati m'mimba mwake ukuwonjezeka pa mapeto a mwamuna kapena amachepetsa pa mapeto akazi, ulusi tapered. Ngati ma diameter onse ali ofanana, ulusiwo ndi wowongoka.
Kuyeza kutalika kwa ulusi
Mukazindikira ngati mukugwiritsa ntchito ulusi wowongoka kapena wopindika, chotsatira ndicho kudziwa kukula kwa ulusiwo. Apanso, gwiritsani ntchito vernier caliper kuyeza ulusi wakunja kapena ulusi wamkati kuchokera pamwamba pa dzino mpaka pamwamba pa dzino. Kwa ulusi wowongoka, yesani ulusi uliwonse wathunthu. Kwa ulusi wopendekera, yesani ulusi wachinayi kapena wachisanu.
Miyezo ya mainchesi yomwe imapezeka ikhoza kukhala yosiyana ndi miyeso yodziwika ya ulusi womwe watchulidwa. Kusintha kumeneku kumachitika chifukwa cha kulekerera kwapadera kwa mafakitale kapena kupanga. Gwiritsani ntchito kalozera wozindikiritsa ulusi wa cholumikizira kuti muwone kuti kukula kwake kuli pafupi ndi kukula koyenera momwe mungathere. ulusi-pitch-gauge-miyeso-chithunzi
Tsimikizirani mayendedwe
Chotsatira ndicho kudziwa kukwera kwake. Yang'anani pa ulusi uliwonse ndi pitch gauge (yomwe imadziwikanso kuti chisa) mpaka yofanana bwino ipezeke. Maonekedwe ena a Chingerezi ndi metric ulusi ndi ofanana kwambiri, kotero zingatenge nthawi.
Khazikitsani mamvekedwe amtundu
Chomaliza ndikukhazikitsa mulingo wa phula. Pambuyo pa kugonana, mtundu, m'mimba mwake mwadzina ndi phula la ulusi zatsimikiziridwa, muyeso wozindikiritsa ulusi ukhoza kudziwika ndi kalozera wozindikiritsa ulusi.
