Ukupakisha: ukwakheka, iintlobo, isicelo.

Ukupakisha glands ke itywina eqhelekileyo, esetyenziswa ngokulitywina izixhobo ezahlukeneyo. Le yokusebenza Umgaqo ngokubekwa ilula: ngoncedo yobunzima bayo kuyafikelelwa kwamalunga ungamalungu. Matywina zisetyenziswa kuphela xa ezisebenza kwiindawo mobile, kodwa umsebenzi lokutywina kuyaphawuleka ahambisane azikhuli (umz, kwimibhobho).

Yintoni ku

Ndlala nokupakishwa aluka zezingxoxo ngohlobo umtya olubuxande kwicala okanye isikwere. Ngokuxhomekeke kwiimeko yesicelo (uxinzelelo, umthwalo eliguqukayo, lobushushu) gasket eyenziwe carbon ifayibha TRH, kwaphuculwa nokubethelela eziseko amalaphu zonke iintlobo ngeentsontelo okanye polytetrafluoroethylene (PTFE).

apho kusetyenziswa

Nokupakishwa for glands kusetyenziswa njengoko kukhankanyiwe ngasentla, ngenxa yokuvalwa:

• Imibhobho clutch fixed and eziphathekayo;
• autoclaves;
• iimpompo;
• compressors;
• valve;
• ngabenzi kunye nezinye iiyunithi.

Kwakhona kwiinkalo zamashishini:

• negesi;
• ioli;
• usetyenzwe;
• ukudla;
• nuclear.

Indawo yokuyisebenzisa:

• ioli;
• umphunga esibaselwe;
• amanzi;
• gases (kubandakanywa liquified);
• izinto afana nolaka;
• iimveliso zepetroliyam.

iimpawu

uphawu ndlala neneempawu kubalulekile zilandelayo:

• ukumelana chemical (inertness) kwiimeko ezahlukeneyo banqande;
• umlinganiselo omncinane kunobunye (ukuncitshiswa eziphathekayo lokuhla kumacandelo ezinokususwa izityalo);
• ukumelana radiation;
• amandla;
• ingqibelelo;
• ukufudumeza ukumelana;
• ukhuseleko eziphilayo;
• Ukwehluleka nokuguga (hayi akayeki ngexesha ulondolozo kunye nokusebenza);
• luthambe (nokuvuselelwa ukusetyenziswa kwezixhobo).

kufuneka Ziziphi iimpawu ilifa ukupakisha namadlala

Imithetho ukubeka iimfuno ezizodwa iintambo. Ezidweliswe apha zezona zibalulekileyo.

1. Le gasket kufuneka afakwe engasebenziyo. Ubuncinane, izinto zokwenza imveliso kufuneka sisabele phezu ukudibana kunye detachable eliphakathi okanye guqula umgangatho zalo ezisisiseko. Umzekelo, ukuba ukupakisha ndlala isetyenziswa ngokulitywina ufakelo (column scrubber) kuzo igesi bako, kunye acid okanye kwealkali, isiseko oil seal ukuba acid- kwaye kwealkali ezingatshiyo. Kunjalo ukuba uglevodorozham (ipetroli, oyile, igrisi). Ukuchithwa ndlala ngokuqinisekileyo kunokukhokelela ukusilela itywina, ingozi, ilahleko wezenzi njalo-njalo.
2. Kwemithambo ndlala ukupakisha kufuneka ukumelana amaqondo aphezulu kunye noxinzelelo oluphezulu. Ingakumbi imihlathi neyanamhlanje neyanamhlanje ioli lwenziwa kwiqondo eliphezulu. Ukumosha kunokukhokelela kukwehla ubume yeemveliso neyanamhlanje, nangokurhala, ukukhutshwa umphunga ngaphandle yaye dubulo.
3. Ukuba amatywina gasket zisetyenziswa ukukhokela kwimixube, kufuneka zimelane ukutshintsha imithwalo. Umzekelo, ngokuba ngokulitywina ezihambayo sokumpompa ibhokisi Akunakuba kufuneka ukuxhathisa frictions. Ukongeza, le gasket kufuneka zimelane lingonakali. Ukulungiselela le njongo, ukuba ezinikezwa zizinto ezahlukeneyo, ezifana Teflon.

Asimele lokukhathalela imithetho

Ngalinye imigangatho imveliso ethile yayo, indlela engcono yokusebenzisa kwaye ufake amatywina gasket. Zonke izinto iquka iimfuno inkalo ebalulekileyo ezifana nokhuseleko. Ukungaphumeleli ukuthobela imiqathango ufakelo (status, yengxinano lonxibelelwano, inani amakhonkco gasket) kunye nokusebenza kungabangela ngemiphumo bumandundu. Aze ngokunjalo ke wonke amanqaku kufuneka kuqwalaselwe:

• imithetho isicelo;
• ukukhetha kwezinto;
• Ishedyuli amatywina utshintsho nokupaka;
• Ufakelo yonxibelelwano ezingavuziyo kunye nezixhobo.

Types packings

Ukususela ngokubekwa, enyanisweni, ngentsontelo eyenziwe amalaphu ezahlukeneyo, umahluko uya kwenziwa kuphela cross-candelo, ubume kunye nolwakhiwo ngokufaka. Elaziwa kakhulu ezifana nokwenziwa packings:

• grafayithi;
• asbestos;
• PTFE;
• yokubekwa imicu zokwenziwa;
• asbestos-free.

grafayithi nokupaka

Ezenziwe ngefoyile ye lwesamente. Izinto eziluncedo zezi gasket kukuba conductivity eliphantsi thermal kunye ukungavumelani kwe kunobunye. Ilishwa - ukuba akuvumelekanga ukuba isetyenziswe bume nokuqwalaselwa eliphezulu nitrogen, chloride kunye chromium kusitsha.

uhlobo asbestos

Le nokupakisha seal esetyenziswa kwiindawo bako, njengoko uhlangabezana njani nale amaqondo obushushu aphezulu kunye nengcinezelo. iimpawu zayo: AC, AP, ZOMOYA, AGP. Ezi gasket asebenza ioli, isinyithi kunye noshishino negesi, ngokunjalo kushishino ngomatshini.

PTFE

Flexible kunye ukumelana neemeko ndlongondlongo. Ezi nkcukacha zezi packs kukuba ukuze isetyenziswe kwiindawo apho kukho chlorine. Zisetyenziswa kwi zamayeza, ioli kunye imichiza mveliso.

Gasket of olulingana

Ezo zamanzi ziyamelana lingonakali. Bona baxhaphaza kwi Intlama nePhepha, iikhemikhali kunye noshishino oyile.

asbestos-free

Kusenokubakho iindidi ezahlukeneyo: inxenye yabo luqiniswe ngocingo nobhedu, yaye ezinye nezongezelelo ke buzane ngamanqatha. Kuxhomekeka imihlaba ukusetyenziswa sohlobo oluthile ikhethiwe.

Ngokutsho isakhiwo core gasket ezahlukeneyo cross-ukusika, multi-umaleko nabangatshatanga-umaleko aziluki. Impompo nokupaka ndlala inokuba icandelo le-3 ukuya ku-50 mm, ngokuxhomekeke kwinjongo yaso.
