Roj hmab o-rings yog tsim los kaw kev sib txuas ntawm ntau qhov chaw, ob qho tib si ruaj thiab txav mus. Cov khoom no kuj siv rau hauv kev tsim kho ntawm hydraulic thiab pneumatic units thiab cov khoom siv. Xav txog cov yam ntxwv thiab kev faib tawm ntawm sealing rubber rings raws li GOST.

cov ntaub ntawv dav dav

Cov peev txheej ntawm cov roj hmab sealing nplhaib yog qhov dav heev. Lawv siv rau hauv cov khoom siv tu cev, lub tshuab hluav taws xob sab hauv, cov kav dej phwj tuaj, cov kav dej, cov twj, thiab lwm yam.

Kev foob roj hmab nplhaib tuaj yeem muaj qhov x-puab, puag ncig lossis duab plaub. Txawm li cas los xij, tsis hais txog ntawm daim ntawv, lawv cov yam ntxwv kev ua haujlwm yuav tsum ua raws li cov kev txwv tsim los ntawm GOST. Roj hmab sealing rings ntawm hom puag ncig, piv txwv li, yog tsim raws li Lub Xeev Standard 9833-73.

Cov yam ntxwv ntawm lub cev ntawm cov khoom sib txawv nyob ntawm qhov xav tau siv. Sealing rubber rings tuaj yeem ua elastic, nruj,tiv taus qhov kub thiab txias, qhov cuam tshuam tsis zoo ntawm ib puag ncig hnyav thiab ntau yam tshuaj.

khoom

Nws xaiv yog nyob ntawm cov khoom ntawm cov kua dej ua haujlwm uas cov khoom tuaj rau hauv kev sib cuag. O-rings tam sim no muaj:

• rubber;
• rubber;
• Ysilicone;
• leather.

Yog tias cov kua uas cov khoom sib cuag tuaj yeem cuam tshuam rau nws qhov tsis zoo, piv txwv li, roj muaj kev puas tsuaj rau roj hmab, ces siv cov roj hmab foob. Vim li cas? Cov khoom no tiv taus cov tshuaj muaj nyob hauv cov roj.

txiaj ntsig

Qhov txiaj ntsig tseem ceeb ntawm O-rings yog:

1. Yooj yim rau nruab.
2. Durability.
3. High functionality.

Qee zaum, cov kev ntsuas no tseem ceeb heev. Piv txwv li, lawv tseem ceeb heev thaum txhim kho lub kav dej.

Qhov zoo dua ntawm cov khoom lag luam yog tias lawv tsis poob lawv cov khoom txawm tias tom qab ob peb lub rooj sib dhos / disassembly ntawm cov qauv. Lub rooj zaum yog muab nyob rau hauv cov ntsiab lus ntawm ib puag ncig zoo li. Nws pab txhawb kev teeb tsa ntawm O-ring.

Kev siv cov khoom sib dhos

Ib pawg ntawm cov nplhaib square feem ntau yog siv los kaw qhov kev sib txuas zoo li qub. Nws raug tso cai siv cov khoom zoo li no hauv cov khoom txav, tab sis muaj me ntsisntau yam ntawm kev txav. Qhov no siv tshwj xeeb rau flanged kev sib txuas thiab li qub.

Feem ntau, cov ntsaws ruaj ruaj square yog siv hauv cov kav dej sib txuas rau ntau lub hom phiaj. Cov khoom lag luam zoo li no muab kev sib khi zoo.

dej ua haujlwm tuaj yeem yog dej (txias / kub), alkali, kua qaub, chav, roj.

Kev xaiv tshwj xeeb

Thaum txhim kho square seals, qhov kev tso cai compression txwv yog 0.1-0.2 hli. Qhov nruj ntawm kev sib txuas tau ua tiav thaum lub nplhaib hloov pauv los ntawm kev ua haujlwm siab ntawm qhov chaw ua haujlwm.

Txhua lub nplhaib hauv lub teeb muaj nws tus kheej tsim. Nws tso cai rau koj los txiav txim siab txog qhov dav thiab muaj peev xwm ntawm kev siv cov khoom hauv ib qho xwm txheej. Thawj tus lej yog lub qia txoj kab uas hla, qhov thib ob yog lub tog raj kheej, thiab qhov thib peb yog lub nplhaib qhov siab.

Rubber O-Ring (GOST 9833-73, 18829-73)

Raws li txoj cai, cov khoom siv no yog siv rau hauv cov pob qij txha ntawm cov qauv zoo li qub. Txawm li cas los xij, qee zaum nws raug tso cai siv hauv kev sib txuas dynamic, yog tias muaj kev sib hloov, sib hloov, oscillatory txav.

Kev faib tawm ntawm cov khoom yog ua raws li hom khoom:

• Rubber sealing rings ntawm ntu ntu raws li GOST 18829-73. Cov khoom no yog siv rau hauv pneumatic, hydraulic, roj teeb.
• Heat-frost-acid-alkali-resistant seals (TMKShch). Cov nplhaib no yog siv rau hauv cov kav xa dej thauj alkali, kua qaub, lwm yam tshuaj, suav nrogtus lej ntawm qhov kub siab.
• Rubber rings raws li GOST 9833-73. Cov khoom no yog tsim los siv rau hauv kev lag luam zaub mov, piv txwv li lawv tuaj yeem nkag mus rau hauv kev sib cuag nrog zaub mov.
• Oil-resistant (MBS) cov ntsaws ruaj ruaj yog siv, feem, hauv cov khoom siv uas nws cov dej ua haujlwm yog roj thiab roj av.

Main parameters

Lub puab kab ntawm cov roj hmab O-ring nws txawv ntawm 1mm txog 2000mm. Lub cheeb tsam tuaj yeem yog 0.5-20mm. Txhawm rau kom yooj yim, cov npe sib raug raug siv rau cov khoom lag luam.

Piv txwv li, yog tias peb tham txog ib txheej ntawm cov ntsaws ruaj ruaj rau cov kav dej sab hauv:

• thawj 3 tus lej qhia txog txoj kab uas hla ntawm qia uas muab lub nplhaib;
• 3 tom ntej no yog txoj kab uas hla ntawm lub tog raj kheej (cov khoom tau muab tso rau hauv nws);
• khoom tuab yog qhia los ntawm xya thiab yim tus lej;
• chav kawm raug - cuaj;
• rubber type - tenth.

Qee zaum, qhov sib txawv me ntsis ntawm qhov tsis muaj tseeb los ntawm cov uas tau muab rau hauv cov cim tau tso cai.

Cov Cai Siv

Roj hmab foob tuaj yeem siv rau qhov kub ntawm -60 txog +250o C. Cov duab tseeb nyob ntawm seb hom khoom siv.

Yog tias peb tham txog lub siab, ces nrog kev sib txuas zoo li qub, nws yuav tsum tsis txhob ntau tshaj 500 atm, thiab yog tias muaj zog (tshwj xeeb tshaj yog cov kua ua haujlwm yog roj, roj, dej, roj) - tsis ntau tshaj 350 atm. Yog hais tias rings yog siv nyob rau hauv cov cua installation rauCov ntsaws ruaj ruaj ntawm cov khoom sib txuas, lub siab tsis tuaj yeem tshaj 100 atm.

Cuffs

Cov khoom no yog siv rau qhov uas tsis tuaj yeem ntsia tsis tau. Lawv tau siv, tshwj xeeb, hauv cov pob qij txha ntawm cov qauv txav tau ntawm cov pas nrig thiab axles uas ua cov kev sib hloov lossis kev txhais lus txav.

Rubber cuffs muaj cov kab sab nraud thiab sab hauv. Cov cuab yeej tshwj xeeb yog siv los ua kom muaj zog.

Cuffs yog cais zoo li lub nplhaib, nyob ntawm daim ntawv thov:

• Txhim kho, qhov tsis sib xws ntawm Lub Xeev Standard 8752-79. Lawv yog siv rau hauv cov pob qij txha ntawm cov khoom hauv cov roj ntxhia, dej, roj diesel.
• Unreinforced, cov ntsuas uas sib haum rau Lub Xeev Standard 6678-72. Cov cuffs no yog siv rau hauv pneumatic units, compressors thiab lwm yam zoo sib xws.
• Unreinforced, cov yam ntxwv ntawm uas sib haum rau Lub Xeev Standard 14896-84. Cov khoom no yog siv rau hauv cov khoom siv hydraulic.
• Cuffs ua raws li TU 38-1051725-86. Lawv tau siv thaum sib khi cov nodes uas txav mus zuj zus.

Storm Sewer Rings

Thaum txhim kho cov kav dej zoo li no, nws tsis pom zoo kom siv cov ntsaws ruaj ruaj. Silicone rings tuaj yeem muab kev nruj nruj ntawm kev sib txuas. Lawv tiv taus kub ntawm -60 txog +200o C.

Qhov zoo ntawm silicone seals yog lawv qhov qis (piv rau cov khoom siv roj hmab) tus nqi. Lawv yogsai tau muaj koob meej nyob rau hauv kev ua lag luam. Qhov no yog vim qhov siab ntawm elasticity, hnav tsis kam, lub zog. Tsis tas li ntawd, cov khoom no muaj nyob rau hauv ntau qhov ntau thiab tsawg.
