Sida Lubricants iyo Media Compatibility ay Ugu Daraan Kordhaha Qabashada?

Marka seal waxaa ka dhacaya si aan la yaabnayn, taasoo badan yahay in caqabadaha ay ku saarayn qalafka, jirka ama khaladka sida loo galiyey. Laakiin waxa kale oo badan ay ka caawisaa dhammaan dhammaystiran: waxa laga wadaagayaa qalafka la isku dayeyey iyo waxyaalaha ay ku xidhaan.

Xiriirka badeecada, luubrikaanta, iyo waxyaalaha loo isticmaalo waxa laga yaabaa inuu ugu yaraan natiijada qalafka iyo xususha.

Ma aha midna ah ee luubrikaanta ay ku tarisaa qalafka

Kuligooda badeecada ay ku jiraan xusuus kala duwan marka ay la isku dayeyeen luubrikaanta iyo kemikalka kale.

Luubrikaantii qaar ka mid ah ay leedahay tiro yar oo ku tarisaa qalafka, laakiin luubrikaantii kale ay ka dhacdaan badbaadinta fysigaal ah ee ka dhasha in ay ugu yar yahay natiijada.

Badbaadintu waxa ay ku jirtaan si aan la yaabnayn marka loo galiyey, laakiin waxa ay ku muuqataa si caddeyn marka loo isticmaalo si degdeg ah.

Nabada caafimaadka ayaa ku jira:

Dheeriyada ka badan

Qaboojinta

Ku xirnaya

Kala jiid mashquulka

Dhacdaynta xadaha

Marka badbaadintu ay dhacday, waxa ay ku jiraan in ay ugu yar yahay in ay qalafka ku xidho.

Luubrikaanta loo galiyey waxa ay leedahay tiro yar oo ka badan oo dadka badan ay uga garanaysaa

Lubricating a seal during installation is generally considered good practice. It reduces assembly friction and helps prevent damage during startup.

However, the wrong grease can create compatibility problems before the equipment even begins normal operation.

If the grease reacts negatively with the elastomer, the sealing material may absorb components of the lubricant and experience dimensional changes.

Selecting a grease that is chemically compatible with both the seal material and the operating medium helps avoid unnecessary risks.

Different Media Require Different Material Choices

Seal material selection should always consider the process fluid.

Tusaale:

Mineral oils are commonly paired with NBR materials.

Higher-temperature synthetic lubricants often require FKM compounds.

Water-based environments may require specially formulated elastomers.

Chemical media may demand materials with enhanced resistance to acids or alkaline substances.

Lama taal elasitomeer ah ay la leeyihiin si wanaagsan ee ku jira dhamaan xagga qaybaha.

Oo fahminta waxa ka mid ah habka dhaqanka iyo xagga shaqaynta waa muhiim ah ilaa in la dhisayo waxa loo isticmaalo.

Dhacdaynta ugu horreysa ee kubadka mararka qaar ayaa bilaabmaa marka la isku xidho waxa ka mid ah kimiyada

Kubadka ayaa noqon karaa si wanaagsan oo ku jira xagga mekaniikada, haddaaba waxa ka mid ah kimiyada ayaa bilaabmay.

Marka waxa loo isticmaalo ay badan, gacanta ka soo baxa, quruxa, iyo qalafka ayaa ka sii socda. Markaasaa dhacdaynta ayaa noqon karaa natiijo la yaabado oo ka dhacaya xagga ugu horreysa.

Sidaas darteed ayaa dhacdaynta mararka qaar ay ku dhacdo si fiican, waxayna ku dhacdo si aad u wanaagsan.

Xasiloonida dhacdaynta oo ka dhacaya waxa loo isticmaalo

Ku xidhinta waxa loo isticmaalo ee kubadka waa qayb ka mid ah foomaha.

Waxa loo isticmaalo ee ku xidhinta kubadka, habka dhaqanka, goobta berriyada, iyo habka ugu yar ee ku xidhinta ayaa loo tixgelin karaa. Koox ka mid ah oo la xidhiyey si wanaagsan ayaa ka saaraya xaaladka dhacdaynta iyo ay caawino in la kor ugu yar gacanta kubadka.

Kadarka badan, xirfadka dhexeeya ee qurux ka mid ah ayaa ku salaysan karaa maalintii dheer ee ku saabsanayaa qurux ka mid ah, laakiin sidoo kale si wanaagsan ayaa ku saabsanayaa xiriirka ku jira oo dhan.
