Chidziwitso choyambirira cha ma gauges a ulusi
Ulusi wa ulusi ndi geji yomwe imagwiritsidwa ntchito poyesa ngati ulusi ukugwirizana ndi malamulo. Ma ulusi amapulagi amagwiritsidwa ntchito poyesa ulusi wamkati, ndipo ma ring ring gauge amagwiritsidwa ntchito kuyesa ulusi wakunja.
Ulusi ndi chinthu chofunikira komanso chomwe chimagwiritsidwa ntchito nthawi zambiri. Ulusi umagwiritsidwa ntchito makamaka pakulumikizana kwamapangidwe, kulumikizana kusindikiza, kutumiza, kuwerenga ndi kunyamula katundu ndi zina. Kuchokera kuzinthu zomwe zimagwiritsidwa ntchito nthawi zambiri mpaka kuzovuta kwambiri (kutentha kwambiri, kuthamanga kwapamwamba, dzimbiri kwambiri), kuchokera pamtundu wovuta mpaka ku chete, mwachidule, zimakhala ndi ntchito zosiyanasiyana.
1. Ulusi wamba (womwe umatchedwanso American thread kapena metric thread) M
2. Ulusi wogwirizana wa ku America ulinso UNC, UNF, UNEF, UN, UNS series
3. Ulusi wa zitoliro zosamata (zingwe zakale zapaipi zozungulira)
4. Ulusi wa trapezoidal
5. Ulusi wina
NPSM-American Standard Mechanical Connection Straight Pipe Thread: Ulusi wamkati ndi wakunja uwu umagwiritsidwa ntchito polumikizana ndi makina aulere popanda kukakamiza mkati. Chogulitsacho chili ndi chitoliro chowongoka choyimitsa pulagi chowunikira.
NPSL - Ulusi Wowongoka wa Pipe wa American Standard Lock Nuts: Ulusi wamkati ndi wakunja uwu umagwiritsidwa ntchito polumikizana ndi ulusi wotsutsana ndi chakudya.
NH - American Standard Fire Hydrant Thread: Ulusi wamkati ndi wakunja uwu umagwiritsidwa ntchito popangira zida zozimitsa moto, ma hose amadzi am'munda, mankhwala ndi zikepe, ndi zina zambiri.
NPSH-National Standard Hose Coupling Threads: Ulusi wamkati ndi wakunja uwu umagwiritsidwa ntchito popanga nthunzi, mpweya, madzi ndi zina zolumikizira mapaipi.
NPSC-American muyezo chitoliro kugwirizana ndi ulusi chitoliro chowongoka: olowa chitoliro ali ndi mbiri ulusi chimodzimodzi monga mkati mowongoka chitoliro ulusi. Pamene ulusi wakunja wa tapered NPT umagwiritsidwa ntchito pa msonkhano wa kusindikiza kusindikiza, kumangirizidwa ndi wrench, ndipo nthawi zambiri amatha kupanga mgwirizano wosindikizidwa. Amagwiritsidwa ntchito kwambiri pamapaipi otsika kwambiri. dongosolo la msewu.
NPSF-National Standard Oil Dry Seal Thread: Ulusi wamkatiwu umagwiritsidwa ntchito popanga msonkhano wosasindikizidwa ndi ulusi wakunja wa NPTF pazida zofewa kapena zitsulo zachitsulo.
NPSI - American Standard Dry Seal Intermediate Threads: Ulusi wamkatiwu umagwiritsidwa ntchito popanga zida zolimba kapena zolimba zokhala ndi ulusi wakunja wa PTF-SAE, koma zitha kugwiritsidwanso ntchito pamisonkhano yayitali yokhala ndi ulusi wakunja wa NPTF.
Taper gauge ya masilindala a gasi
Ulusi wapadera wa taper wa masilindala a gasi umagwiritsidwa ntchito polumikizana pakati pa masilindala ndi mavavu a masilindala osiyanasiyana achitsulo (monga masilindala okosijeni, masilinda agesi, masilinda a acetylene, ndi zina). Kudalirika kwa kutseka ndi kusindikiza kwa maulumikizidwe a ulusi ndiye chinthu chachikulu chowonetsetsa chitetezo popanga ndi kugwiritsa ntchito.

Metric trapezoidal thread Tr
Ulusi wa trapezoidal umagwiritsidwa ntchito makamaka pakufalitsa (chakudya ndi kukweza) ndi zida zosinthira malo, ndipo zimagwiritsidwa ntchito kwambiri mumakampani opanga makina. Kulekerera kwa ulusi wa metric trapezoidal pazifukwa wamba kumatengera kulolerana kwa ulusi wamba wa metric, ndipo palibe kulekerera kosiyana kwa magawo amtundu uliwonse monga lead lead (pitch) ndi sub-measurement angle. Chifukwa chake, ulusi wa trapezoidal uwu siwoyenera kutengera ulusi wolondola womwe uli ndi zofunika kwambiri pakufalitsa kulondola. Ulusi wolondola wa trapezoidal uyenera kuwonjezera kulolerana kwa magawo a ulusi pawokha pamaziko a ulusi wa trapezoidal.
Ulusi wa trapezoidal ukhoza kugwiritsidwanso ntchito pomangirira kulumikizana. ACME ulusi ndi metric serrated ulusi gauges zilipo
Makina oyesera aku America omangirira ulusi (UN, UNR, UNJ, M ndi MJ)
Chifukwa cha kusamvetsetsana kochuluka, zoopsa zina ndi zofunikira zachuma m'munda wa kudziwika kwa ulusi, zabweretsa mavuto ambiri ku kuvomereza kwa mankhwala a ulusi ndikukwirira zoopsa zambiri zobisika ku khalidwe la mankhwala opangidwa ndi makina. Pofuna kuthetseratu vutoli, dziko la United States lachita kafukufuku wochuluka pa kufufuza kwa ulusi, ndipo linapereka ndondomeko yowunikira ulusi (muyezo wa ASME) ndi kusatsimikizika kwa data ya 60º thread gauge measure (ASME technical report). United States ikutsogola padziko lonse lapansi pakukonza ulusi ndi ukadaulo woyesera. M'tsogolomu, maiko ena padziko lapansi aphunzira kuchokera ku United States ndikukhazikitsa njira zawo zoyezera ulusi kuti apititse patsogolo ulusi wawo. Ngati ambiri ogwira ntchito zaukadaulo m'dziko lathu angaphunzire ndikuzindikira ukadaulo uwu waukadaulo wozindikira ulusi posachedwa, mtundu wa zinthu za ulusi m'dziko lathu udzakhala wabwino kwambiri, ndipo tidzachotsa momwe zinthu ziliri pakupanga ulusi. .
Kuchokera ku makina oyendera ulusi aku America, mutha kuphunziranso ukadaulo wapamwamba wokonza ulusi ku United States. Mwachitsanzo, kugwiritsa ntchito ukadaulo wozindikira ma geji osiyanitsa kutha kuwongolera kulondola kwa zida zamakina ndi zida zodulira, ndikukonza ulusi womwe uli pafupi ndi kukula koyenera. Pa nthawi yomweyi, moyo wa chida udzawonjezeka.
Zida za Xinfa CNC zili ndi khalidwe labwino kwambiri komanso lolimba kwambiri, kuti mudziwe zambiri, chonde onani: https://www.xinfatools.com/cnc-tools/
