Mu machitidwe a process, maulumikizidwe a ulusi ndi zinthu zofunika kwambiri zamakaniko zomwe zimagwiritsidwa ntchito polumikiza zida zomwe zimayendetsa kusamutsa madzi kapena mpweya. Zolumikizira izi zimakhala ndi mizere yozungulira yopangidwa pamwamba pa (yachimuna) kapena mkati (yachikazi), zomwe zimathandiza kuti maulumikizidwewo akhale otetezeka komanso osataya madzi. Ulusiwo ukalumikizidwa, umapanga mgwirizano wolimba wamakina womwe ungathe kupirira kupsinjika kosiyanasiyana kwa ntchito.
Maulalo okhala ndi ulusi samangogwira zinthu pamodzi komanso amateteza kuti zinthu zisamatuluke. Pali mitundu iwiri yayikulu ya ulusi: ulusi wofanana ndi ulusi wofewa. Iliyonse imasiyana malinga ndi geometry ndi sealing mechanism.
Ulusi Wofanana
Ulusi wowongoka, womwe umadziwikanso kuti ulusi wowongoka, uli ndi mainchesi ofanana komanso mawonekedwe a ulusi kutalika kwake konse. Kapangidwe kofanana kameneka kamapangitsa kuti kulinganizika ndi kuyika kukhale kosavuta. Komabe, popeza ulusiwo suchepa, sumapanga chisindikizo kudzera mu kupsinjika kwa radial. M'malo mwake, ungadalire zinthu zothandizira kutseka—monga O-ring, gasket, kapena washer—kuti upewe kutayikira pakagwiritsidwa ntchito mphamvu zambiri. Ntchito yayikulu ya ulusiwu ndikupereka mphamvu yamakina. Kapangidwe kameneka kamapangitsa ulusi wofanana kukhala woyenera bwino pa ntchito zomwe zimafuna kusonkhana ndi kuchotsedwa pafupipafupi, popeza chisindikizo chosinthika chimathandiza kukonza popanda kuwononga ulusiwo.
Ulusi wa Taper
Ulusi wa Taper umapangidwa ndi makina okhala ndi mainchesi ocheperako pang'onopang'ono, zomwe zimapangitsa mawonekedwe a conical. Pamene zigawo zachimuna ndi zachikazi zikulumikizidwa, taper imapanga mphamvu yolumikizirana yomwe imawonjezera kukhudzana kwa ulusi ndikupanga kusakanikirana kwa makina. Kukanikiza kwa radial kumeneku kumapanga chisindikizo chachitsulo ndi chitsulo, chomwe chimakhala cholimba kwambiri pansi pa kukakamizidwa, zomwe zimapangitsa ulusi wa taper kugwira ntchito bwino kwambiri m'makina amphamvu kapena amphamvu okhudzana ndi mpweya kapena zakumwa. Kutseka kwa ulusi wa taper kumawonjezeka ndi kulimbitsa ndi kukakamiza kuwonjezeka, zomwe zimapangitsa kuti pasakhale kufunikira kwa zisindikizo zina m'magwiritsidwe ambiri.
Kuganizira Zosankha
Ulusi wofanana nthawi zambiri umakondedwa m'makina otsika mphamvu kapena komwe kusinthasintha ndi kusamalitsa bwino zimayikidwa patsogolo. Ndikofunikira kusankha ma gasket kapena mphete zoyenera kuti zitsimikizire kuti kutuluka kwa madzi kumalimba.
Ulusi wa taper umapambana kwambiri m'malo omwe ali ndi mphamvu zambiri, makamaka m'makina a hydraulic, pneumatic, kapena process fluid. Kutha kwawo kudzitseka okha pansi pa mphamvu kumawapangitsa kukhala chisankho chodalirika pansi pa zovuta.
Pakuyika zida, miyezo yofanana ya ulusi imaphatikizapo Metric ndi BSPP (parallel), komanso NPT ndi BSPT (yochepetsedwa). Posankha mtundu wolumikizira, ndikofunikira kuganizira momwe ntchito ikuyendera, kuchuluka kwa kuthamanga, komanso kuyanjana ndi ma interfaces omwe alipo. Ndi zaka zoposa 20 zaukadaulo wopanga zida zoyezera,Shanghai Wangyuanimapereka mitundu yosiyanasiyana ya ulusi wa ma transmitter ndipo imathandizira makonzedwe apadera kuti mulumikizane ndi njira. Chonde musazengereze kulumikizana nafe kuti mudziwe zambiri kapena zofunikira zina.
