Roj hmab cuff yog ib qho ntawm cov tseem ceeb tshaj plaws ntawm cov khoom siv

Roj hmab cuff, los yog caj pas, yog lub nplhaib zoo li lub hnab roj hmab uas tsim los txuas rau cov khoom siv. Roj hmab rings txawv hauv lawv cov configuration thiab muaj kev sib txuas ntawm qhov chaw thiab cov mechanisms ntawm ib hom cylindrical. Lawv tiv thaiv kom txhob nkag mus ntawm cov kua, lubricants thiab cov roj cua hauv cheeb tsam uas muaj qhov qis dua hauv cheeb tsam siab. Tus qauv tsim, nrhiav thiab cov khoom ntawm taub ntswg yog txiav txim siab los ntawm qhov uas lawv siv.

Roj hmab siv zog tuav tes

Tam ntsaws ruaj ruaj npaj rau kev sib khi hauv lub ntau yam shafts uas khiav lag luam nyob rau hauv ntxhia roj thiab lubricants raws li roj, raws li zoo raws li nyob rau hauv cov dej thiab diesel roj, nyob rau theem ntawm kev overpressure tsis pub tshaj 0.05 MPa, thiab cov kev ceev - 20 m / s ntawm ib tug kub ntawm los ntawm - 45 degrees rau +100 degrees.

Cov ntsaws ruaj ruaj yog ob hom, ib qho ntawm ib lub xub pwg hnab tawv nqaij tsis anther, thiab ob - nrog anther. Khaub ncaws tsis antheres tiv thaiv kom tsis txhob to ntawm qhov nruab nrab nruab nrab, thiab nrog anther - kuj tiv thaiv kom tsis txhob muaj hmoov av. Cov npoo ntawm cov thawv hauv qab no yog tsim nyob rau hauv ob txoj kev - ntawm machining thiab los ntawm molding. Txhua daim ntaub qhwv yuav tsum cim. Cov cim qhia tias cov khoom ntim, qhov twg qhov Performance index 1 yuav qhia tau tias qhov khoom tsis anther, thiab 2 - nrog anther. Tom ntej no, lub caj pas ntim yog qhia: Performance index 1 txhais tau hais tias ntug tau mechanically, thiab Performance index 2 qhia tau hais tias di ncauj yog tsim. Daim duab tom ntej no yog lub kab ntawm lub qhov ncej, tom qab nws mus rau sab nraud ntawm lub caj pas nws tus kheej thiab, thaum kawg, nws qhov siab. Tag nrho cov naj npawb no yog muab tso rau hauv millimeters. Piv txwv, 1,2-60х80х10.

Cov khoom siv roj hmab rub tau los ntawm elastomer thiab nws cov mixtures, butadiene-nitrile, silicone thiab lwm hom roj hmab los ntawm polyurethane. Cov nta ntawm qhov khoom ntawm cov khoom no yog nyob ntawm seb lawv daim ntawv thov, piv txwv li, nyob rau hauv tsheb, mechanical engineering, hauv kev lag luam aircraft thiab lwm thaj chaw.

Ntau yam ntawm roj hmab rau lub chaw ua khoom ntawm cuffs

Raws li twb tau hais lawm, qhov no los yog cov roj hmab cuff yog tsim los siv rau hauv ib cheeb tsam, txuas nrog qhov no, thiab cov khoom siv rau lawv cov khoom siv yog siv txawv. Txhua hom roj hmab muaj tus yam ntxwv ntawm tus kheej thiab muab faib ua pawg.

Roj hmab tawv taub hau kom huv

Tam sim no, nws tsis muaj peev xwm xav txog tej yam dej num hauv cov kav dej tsis siv cov khoom siv roj hmab ntau yam. Cov roj hmab cuff tuaj yeem ua tau ntawm cov ntaub ntawv sib txawv: roj hmab, roj hmab, paronite lossis silicone. Cuffs muab kev sib txuas hermetic ntawm qhov chaw tua hluav taws xob ntawm cov kav dej sib txawv ntawm cov kab diam los nrog cov kav dej. Tsis tas li ntawd, lawv txuas hoses thiab corrugated tubing ntawm ntau diameters nrog dej kav dej.
