Txhawm rau txuas ntau qhov sib koom ua ke rau hauv ib qho qauv sib txuas lossis txuas lawv mus rau saum npoo, tshwj xeeb cov hlua txuas tau siv: ntsia liaj qhov rooj, thauj tog rau nkoj, khawm. Tau kawg, txhua qhov ntawm cov fasteners saum toj no muab kev sib txuas zoo, tab sis txhawm rau kom lub rooj sib dhos dhau los ua kom ntseeg tau thiab ruaj khov, lawv kuj siv qhov kev nthuav dav xws li lub tshuab ntxhua khaub ncaws. Nws yog hais txog cov ntsiab lus uas yuav tham txog hauv kab lus no: peb yuav tham txog lawv hom, lub hom phiaj thiab cov cai ntawm kev siv.
Nws yog dab tsi?
Sealing washers xa mus rau cov khawm ris, kev siv uas tuaj yeem ua kom muaj zog ntxiv thiab ua kom muaj kev sib txuas ntawm cov ntu txawm tias muaj zog dua.
Lub tshuab ntxhua khaub ncaws ua haujlwm zoo li lub qhov ntsaws.
Ntxiv rau kev sib khi lub ntsiab lus txuas, cov khoom txhawb rau:
- txo kev puas tsuaj rau cov ntsia hlau;
- tiv thaiv tus kheej-unscrewing ntawm cov ntsiab lus;
- nce hauv thaj tsam ntawm qhov txhawb nqa.
Lub tshuab ntxhua khaub ncaws tau ua raws li cov ntaub ntawv tswj hwm, thiab qhov no yog GOST 19752-84 "Sealing gaskets. Tsim. Cov yam ntxwv zoo ". Raws li nws, cov khoom lag luam yog tus yam ntxwv:
- nominal thiab puab txoj kab uas hla;
- txheej sab nrauv;
- tuab.
Sealing tshuab ntxhua khaub ncaws, uas lav zoo nruj, tau siv dav hauv ntau yam lag luam:
- tshuaj;
- kev tsim roj thiab roj;
- engineering;
- kev tsim kho.
Ntau yam ntawm cov tshuab ntxhua khaub ncaws sib txawv. Qhov no ua rau nws muaj peev xwm xaiv cov khoom lag luam rau hom haujlwm tshwj xeeb, piv txwv li:
- rau kho polycarbonate;
- hav zoov txheej;
- roj tshuab, thiab lwm yam.
Vim nws lub cev zoo thiab cov yam ntxwv zoo thiab cov yam ntxwv, cov khoom tau siv los ua qhov ntxig rau hauv cov txheej txheem ntawm kev teeb tsa thiab kho qhov txuas mus rau ntau hom txheej puag.
Lawv yog dab tsi?
Muaj kev xaiv dav thiab ntau yam ntawm cov tshuab ntxhua khaub ncaws nrog gaskets los ntawm ntau lub chaw tsim khoom ntawm lub khw muag khoom niaj hnub no . Qhov no yog vim qhov tseeb tias tsis ntev los no cov khoom siv hauv tsev tshiab tau tshwm sim ntau dua thiab ntau dua, uas yog tsim los ntawm cov khoom siv niaj hnub no, thiab rau txhua tus ntawm lawv koj tuaj yeem xaiv lub tshuab ntxhua khaub ncaws tshwj xeeb.
Muaj ntau qhov kev faib tawm yooj yim ntawm cov tshuab ntxhua khaub ncaws. Piv txwv li, lawv tau faib raws li cov khoom siv ntawm kev tsim khoom.
Roj hmab … Yeej, tus qauv zoo li no tau siv hauv cov txheej txheem ntawm kev txhim kho cov ru tsev thiab cov khoom siv sab nrauv rau cov ntoo lossis hlau. Tsis tas li, cov khoom siv roj hmab feem ntau siv thaum tso thiab txuas cov kav dej.
Txhuas … Qhov no yog cov khoom lag luam txhim khu kev qha tshaj plaws thiab zoo tshaj plaws, uas txawv qhov tuab, txoj kab uas hla ntawm sab nrauv thiab sab hauv, thiab cov duab. Xyuas kom muaj kev sib txuas ruaj khov thiab nruj ntawm cov khoom.
Roj hmab-hlau … Roj hmab tshuab ntxhua khaub ncaws nrog lub nplhaib muaj qhov zoo ntawm qhov ua tau zoo: lub zog ua haujlwm siab, lub zog qis coefficient. Nws kuj tseem hu ua kev sib cais kev sib cais, vim tias cov hlua roj hmab tiv thaiv qhov txuas los ntawm xoob thaum lub sij hawm kev co. Tus qauv tuaj yeem tiv taus lub nra hnyav thiab yog tus yam ntxwv ua haujlwm ntev.
Hlau … Hom tshuab ntxhua khaub ncaws, zoo li txhuas, muaj cov khoom zoo, ntawm qhov nws tsim nyog sau cia tsis xeb, tiv taus cov neeg kho tshuab thiab tshuaj lom. Tias yog vim li cas, feem ntau, lub ru tsev tag nrho tau txais kev txhawb nqa los ntawm cov hlau sib khi.
Txhua yam kev teeb tsa thiab kev tsim kho ua haujlwm tau nrog rau kev siv O-rings. Tam sim no, cov tuam ntxhab siv lwm cov khoom siv rau kev tsim cov tshuab ntxhua khaub ncaws - polycarbonate. Cov khoom zoo li no hu ua thermal tshuab ntxhua khaub ncaws.
Cov kws tshaj lij thiab cov tuam txhab tsim khoom thov tias polycarbonate fasteners tsis muaj txoj hauv kev qis dua, piv txwv li, hlau lossis txhuas rings.
Ntxiv rau cov khoom siv, cov khoom sib txawv hauv qhov loj me. Niaj hnub no, qhov xav tau ntau tshaj yog rau cov ntsaws ruaj ruaj hauv qhov ntau thiab tsawg M6, M8, M10, M4, M12 … Rau cov neeg uas muaj kev ua xyem xyav txog qhov loj ntawm cov khoom xav tau, ib txheej, uas suav nrog cov khoom lag luam sib txawv me me, yog qhov zoo tagnrho.
Lawv siv li cas?
Yav dhau los peb twb tau sau lawm tias O-rings tau nthuav dav thiab feem ntau siv hauv ntau hom haujlwm los tsim kev sib zog thiab sib khi ntau dua. Lawv tau siv nyob rau hauv tus txheej txheem ntawm txuas cov ntu rau hlau, pob zeb, cib, plasterboard puag.
Tsis tas yuav sau qhov twg thiab thaum twg los siv lub tshuab ntxhua khaub ncaws. O-ring yog ib feem tseem ceeb ntawm txhua qhov txuas . Kev tsim kho, ua haujlwm kho tsis tuaj yeem ua tiav thiab raug yog tias lawv tau ua yam tsis muaj O-ring. Qhov loj tshaj yog xaiv cov khoom raug. Hauv qhov no koj yuav tsum tsom mus rau cov khoom siv los ntawm lub tshuab ntxhua khaub ncaws tau ua, thiab ntawm nws qhov loj me.
