M'makina ogwiritsira ntchito, maulalo olumikizidwa ndi zinthu zofunika zamakina zomwe zimagwiritsidwa ntchito polumikizana ndi zida zomwe zimatengera kusamutsa madzi kapena gasi. Zopangira izi zimakhala ndi ma helical grooves opangidwa ndi makina akunja (achimuna) kapena mkati (aakazi), zomwe zimathandiza kulumikizana kotetezeka komanso kosadukiza. Zikakwerana, ulusiwo umapanga chomangira cholimba chomwe chimatha kupirira zovuta zosiyanasiyana.
Kulumikizana kwa ulusi sikumangogwira zigawo pamodzi komanso kuteteza kutulutsa kwa media. Pali mitundu iwiri yoyambirira ya ulusi: ulusi wofanana ndi wa taper. Iliyonse imasiyana mu geometry ndi makina osindikizira.
Parallel Thread
Zomwe zimatchedwanso kuti ulusi wowongoka, ulusi wofanana uli ndi m'mimba mwake ndi mbiri ya ulusi motalika. Maonekedwe a yunifolomuwa amathandizira kulumikizana ndi kukhazikitsa. Komabe, popeza ulusiwo sumasefukira, sikuti umapanga chisindikizo mwa kukakamiza kwa radial. M'malo mwake, zitha kudalira zida zosindikizira - monga O-ring, gasket, kapena washer - kuteteza kutayikira pakugwiritsa ntchito kuthamanga kwambiri. Ntchito yaikulu ya ulusi ndi kupereka mphamvu zamakina. Kapangidwe kameneka kamapangitsa kuti ulusi wofanana ukhale woyenera pa ntchito zomwe zimafuna kusonkhana pafupipafupi komanso kutha, popeza chisindikizo chosinthikacho chimathandizira kukonza bwino popanda kuwononga ulusi.
Taper Thread
Ulusi wa taper umapangidwa ndi m'mimba mwake pang'onopang'ono, ndikupanga mawonekedwe owoneka bwino. Pamene zigawo za amuna ndi akazi zikugwira ntchito, taper imapanga chiwongoladzanja chomwe chimawonjezera kukhudzana kwa ulusi ndikupanga kusokoneza kwa makina. Kuponderezedwa kwa radial kumeneku kumapanga chisindikizo chachitsulo-to-zitsulo, chomwe chimakhala cholimba pansi pa kukanikiza, kupangitsa kuti ulusi wa taper ukhale wogwira mtima kwambiri pamakina othamanga kwambiri kapena osunthika ophatikiza mpweya kapena zakumwa. Kusindikiza kwa ulusi wa taper kumayenda bwino ndikumangirira ndi kuwonjezereka kwamphamvu, ndikuchotsa kufunikira kwa zisindikizo zowonjezera pazogwiritsa ntchito zambiri.
Kuganizira Zosankha
Ulusi wofanana nthawi zambiri umakondedwa m'makina otsika kwambiri kapena pomwe kukhazikika komanso kuwongolera bwino kumayikidwa patsogolo. Ndikofunikira kusankha ma gaskets ogwirizana kapena mphete za O kuti mutsimikizire kutayikira.
Ulusi wa taper umapambana kwambiri m'malo opanikizika kwambiri, makamaka pama hydraulic, pneumatic, kapena process fluid system. Kukhoza kwawo kudzisindikiza paokha pansi pa kukakamizidwa kumawapangitsa kukhala odalirika pazochitika zovuta.
Pakuyika zida, ulusi wamba wamba umaphatikizapo Metric ndi BSPP (parallel), komanso NPT ndi BSPT (tapered). Posankha mtundu wolumikizira, ndikofunikira kuganizira momwe mungagwiritsire ntchito, kupanikizika, komanso kugwirizana ndi mawonekedwe omwe alipo kale. Ndili ndi zaka zopitilira 20 pakupanga zida zoyezera,Shanghai Wangyuanimapereka mitundu ingapo ya ulusi wama transmitters ndipo imathandizira masinthidwe anthawi zonse kuti agwirizane. Chonde khalani omasuka kulumikizana nafe kuti mufunsire zina kapena zofunikira zina.
