Waa maxay waddamada la horumaray ee uunaha biddiiska Skeleton iyo waa maxay sababkii in lagu horey u socdo habka kaydinta?

Muddada jidka ilaajinta waxaa tafatuma NBR (nitrile rubber) waxaa leh sannadkoodi 3-5 iyo FKM (fluororubber) waxaa leh sannadkoodi 5-8. Waqtiga lahaynta, dhexeerrada jidka, xagga, nidaamka, iyo heerka ozone waa in lagu hortaguro, sidoo kale in lagu hortagro isbeddelka muuqadda. Hase yeeshe, jidku waxaa uun kara inuu daahdaado mudo ka hor oo uu uun karo.

Tusaalooyinkan waxaa si cad ku qoriyay istaandaardida ka baxsan dunida sida DIN 7716 iyo ISO 2230.

Maxaad jidka ilaajinta aydhaha leedahay muddo lahayn?

Materiyahan jirta ah ee xarigaha ayaa ah koombe, kuna waa laha dadka dhexdooda in koombe ay ka sii socdaan. Tusaale ah oxidation, ozone aging, thermal aging, molecular chain breakage, iyo kala wareegista elasticity. Badbaadkani waxay noqon karaan in xariiguhu way ku qalabmaan, way ku gurarmaan ama way kala wareegi karaan flexibility haddana marka lama istaamino, taasoo dhinaca kale inay saamaysataan inay kala duwan tahay. Si kale, xarigaha “way ka sii socdaan”, taasoo ah sababta muhiminta aad ugu yaqaana inay leedahay muddo horreeya.

Maxaa loo bixi karaa marka lagu halgamaayo xarigaha koombe?

Sida Shaanfeng (Brands under its umbrella include NQKSF) technical standards, in lagu halgamo alaabta koombe ee sealing waa in lagu maareyno DIN 7716 iyo ISO 2230:

Jabin:

Halgamaa 15°C ilaa 25°C.

Jeexjinta:

Xalka habboonka caadi ah waa in ka yar 70%.

Ka hortagga ilmo iyo UV exposure:

Ilmuhu uu kala saamayn yahay koombe si ay ka sii socdaan.

Ka hortagga or environment:

Ka fogid in aad u qorsheysid qotaska sare iyo xoolaha abuuraya static.

Ka hortagga in aad qabsado, iddo, ama isbeddel fashax:

Lakabaha kawka waxay u baahan yihiin inay sii socdaan shaacihii origna.

Ilaal kaadhka ku xidha:

Kaadhan origna waa ilaalinaya saafka ka ay dhex maran karaan habjo, buurta iyo naxdin.

Astamaha warshada sidoo kale tixgelinaya:

Ji'da lahaynta lagu xidho weyndhigga ha aha mid aysan ka baxin 25°C.

Saafka weyndhigga waxaa la xidha horizontaal in lagu hortago isbedel shaaci.

Ka hortag in la laaso kiimikada ama wasaarka la istaaganta.

Shuruudahaasu wada la ixtiraaminaysaa muddada waqti ee saafka weyndhigga iyo jaamcinta lagu xidha.

Tusmo

Si loo hubiyo in saafka weyndhigga uu siiyo awood dheer marka loo isticmaalo, waxaa loo qoray in lagu hesho jadooogtan soo socda:

1. Abnaqda nidaamka maalgashiga

Fikir taariikhda abshirka, khayraadaha iyo lambara batch-ka. Haddo 'first-in, first-out'.

2. Abaar joojinta aad u adeegsato standaardada

Ilaal waddooyinka 15°C ilaa 25°C.

Ilaal jeedka 40% ilaa 70%.

Ka hortag dhexeeya iyo mugga oo leh osoon.

Kaga cajiin kalaamka si lacag la'aan.

3. Ka fekereen falka oil seal-ka la joojiyey

Eeg kuwa hardening, cracks ama deformation.

Muddada maalinle ee skeleton oil seal-ka waxa uu la xidhan yahay joojinta. Kan keliya haddii joojinta leh waddo, jeed iyo dhexe si toos ah, caabuuhu ayaa ka hayn jabeelad dheer iyo inuu hubiyo inuu hubiyo. Iyadoo loo isticmaalo fabrikiyada, markaas hadal ama qabsadaha, joojinta saxda ah waa muhim in lagu hortago khalad farxad leh.
