COV: muaj pes tsawg leeg, hom, daim ntawv thov.

Packing qog yog ib qho kev foob, uas yog siv rau kev sib khi ntau yam pab kiag li lawm. Cov kev khiav hauj lwm hauv paus ntsiab lus ntawm tso yooj yim: nrog kev pab los ntawm nws ceev ceev yog tiav nyob rau hauv cov pob qij txha ntawm qhov chaw. Ntsaws ruaj ruaj yog siv tsis tau tsuas yog nyob rau hauv mechanisms ntawm mobile ntshav, tab sis remarkably zoo li qub sealing muaj nuj nqi nrog adhesions (e.g., nyob rau hauv cov kav dej).

Yuav ua li cas yog nyob rau hauv

Caj pas packing weave ntawm threads nyob rau hauv daim ntawv ntawm ib txoj hlua ntawm lub los yog square seem. Nyob ntawm seb tus mob ntawm daim ntawv thov (siab, dynamic load, kub) gasket ua los ntawm cov pa roj carbon fiber TRH, zoo txhawb cov me nyuam yaus ntawm tus fabrics ntawm tag nrho cov hom ntawm ropes los yog polytetrafluoroethylene (PTFE).

qhov twg siv

Packing rau qog siv raws li hais saum toj no, rau kev sib khi:

• taag thiab rooj noj clutch piping;
• autoclaves;
• twj;
• compressors;
• li qub;
• mixers thiab lwm yam units.

Tsis tas li ntawd nyob rau hauv lub teb ntawm kev lag luam:

• nkev ntau lawm;
• roj;
• ua;
• khoom noj khoom haus;
• nuclear.

Kev khiav hauj lwm puag ncig:

• roj;
• superheated chav;
• dej;
• gases (xws li liquified);
• sib txhoj puab heev tshuaj;
• uas siv roj av.

nta

Caj pas foob muaj cov nram qab qhov tseem ceeb cov yam ntxwv:

• tshuaj lom neeg kuj (inertness) rau txawv txhoj puab heev tej yam kev mob;
• me me kev ntsuas ntawm kev sib txhuam (tangible yuav txo tau nyob rau hauv kev luv nqi ntawm rooj noj Cheebtsam ntawm cov nroj tsuag);
• tawg kuj;
• lub dag lub zog;
• kev ncaj ncees;
• thaum tshav kub kub kuj;
• ecological kev ruaj ntseg;
• aversion rau cov laus (tsis ntsws thaum lub sij hawm txij nkawm thiab cov lag luam);
• elasticity (daim ntawv rov ntxiv cov khoom siv).

Yuav ua li cas cov khoom yuav tsum tau muaj packing qog

Cov kev cai kom tshwj xeeb uas yuav tsum tau nyob rau hauv lub xov. Yog no yog cov tseem ceeb tshaj plaws.

1. Lub gasket yuav tsum sib tsaug zog. Thaum kawg, lub raw khoom yuav tsum tsis txhob hnov mob thaum kev sib cuag nrog lub nruab nrab detachable los yog hloov nws yooj yim zoo. Piv txwv li, yog hais tias tus caj pas packing yog siv rau kev sib khi installation (kem Scrubber) nyob rau hauv uas yog corrosive gases, thiab acid los yog alkali, cov roj foob puag yuav acid- thiab alkali-resistant. Tib yam siv rau uglevodorozham (petrol, roj, Greases). Nyias mus nyias caj pas yuav yeej ua tau kom foob tsis ua hauj lwm, kev sib tsoo, tsis reagents thiab thiaj li nyob.
2. Lub packing caj pas li qub yuav tsum mas siab kub thiab siab siab. Nyob rau hauv kev lub distillation txhua ntawm cov roj distillation yog nqa tawm ntawm ib tug kub. To yuav ua tau kom deterioration ntawm nyob tus yeees ntawm cov distillation khoom, o, kev tso tawm ntawm vapors rau sab nraum thiab txawm tawg.
3. Yog hais tias lub gasket cov ntsaws ruaj ruaj yog siv los coj lub mixtures, lawv yuav tsum resistant rau kev hloov loads. Piv txwv li, rau kev sib khi mus qhov chaw tso txuj lom box yuav tsum tau muaj kuj mus frictions. Nyob rau hauv tas li ntawd, lub gasket yuav tsum resistant rau puas. Rau lub hom phiaj no, lawv yog supplemented los ntawm txawv tshuaj, xws li Teflon.

Peb yuav tsum tsis txhob tsis saib tsis xyuas cov kev cai

Txhua yam nws muaj nws tus kheej tej ntau lawm cov qauv, qhov zoo tshaj plaws txoj kev uas yog siv thiab nruab ib lub gasket cov ntsaws ruaj ruaj. Tag nrho cov khoom xws li yuav tsum xws li ib qho tseem ceeb raws li kev ruaj ntseg. Tsis ua raws li lub installation tej yam kev mob (raws li txoj cai, lub ceev ceev ntawm kev sib txuas, tus naj npawb ntawm rings gaskets) thiab cov lag luam yuav ua nyob rau hauv lub loj tshaj plaws yuav tshwm. Thiab yog li ntawd rau tag nrho cov ntsiab lus yuav tsum tau yog:

• kev cai rau cov daim ntawv thov;
• kev xaiv ntawm cov khoom;
• lub sij hawm hloov cov ntsaws ruaj ruaj;
• Installation sealable kev sib txuas lus thiab pab kiag li lawm.

Hom packings

Txij li thaum pw, nyob rau hauv qhov tseeb, yog ib tug qaum ua los ntawm ntau yam ntaub, qhov txawv nws yuav muaj xwb nyob rau hauv tus ntoo khaub lig-section, muaj pes tsawg leeg thiab qauv ntawm weaving. Qhov zoo tshaj plaws lub npe hu xws compositions packings:

• graphite;
• asbestos;
• PTFE;
• tso hluavtaws fibers;
• asbestos-free.

graphite packing

Ua los ntawm tam ci. Qhov zoo ntawm cov gaskets yog hais tias lawv muaj tsawg thermal conductivity thiab coefficient ntawm tsis sib haum xeeb. Tsis zoo - lawv tsis tau tso cai rau siv nyob rau hauv kev kawm uas muaj ntau ntawm nitrogen, chloride thiab chromium tebchaw.

asbestos hom

Qhov no packing cov ntsaws ruaj ruaj siv nyob rau hauv corrosive npuas, raws li nws copes nrog lub siab kub thiab pressures. Nws cim: AC, AP, CUA, AGP. Cov gaskets khiav lag luam nyob rau hauv cov roj, co, thiab cov pa roj kev lag luam, raws li tau zoo raws li nyob rau hauv lub tsheb lag luam.

PTFE

Saj zawg zog thiab resistant mus txhoj puab heev tej yam kev mob. Lub specifics ntawm cov packs yog hais tias lawv yuav tsis tau siv nyob rau hauv chaw uas muaj chlorine. Lawv yog siv nyob rau hauv lub chaw ua tshuaj, roj thiab tshuaj industries.

Gaskets ntawm filament

Tej cov ntsaws ruaj ruaj yog resistant rau puas. Lawv exploited nyob rau hauv lub sis plawv hniav thiab cov ntawv, cov tshuaj lom thiab roj kev lag luam.

asbestos-free

Tej zaum yuav muaj ntau hom: ib co ntawm lawv yog siv tam nrog dag hlau, thiab ib co additives yog impregnated nrog roj. Nyob ntawm seb lub Scope ntawm siv ntawm ib tug tej yam yog xaiv.

Raws li cov qauv ntawm cov tub ntxhais gasket txawv tus ntoo khaub lig-txiav, multi-txheej thiab ib txheej weave. Twj tso kua mis packing caj pas tej zaum yuav ib tug seem ntawm 3 mus rau 50 mm, nyob ntawm seb nws cov hom phiaj.
