12mm En818-8 Silsilad Qaadista Daawaha Xoogga Sare leh oo loogu talagalay Kor u qaadista
Qaybta
Soo bandhigidda badeecadeenii ugu dambeysay, silsiladda kor u qaadista dahaarka ee 12mm En818-8 oo leh awood sare. Silsiladdan kor u qaadista waxaa loogu talagalay inay buuxiso shuruudaha kor u qaadista ugu adag iyadoo diiradda la saarayo badbaadada iyo cimri dhererka.
Cabbirka silsiladda 12mm wuxuu hubinayaa inuu qaadi karo culaysyo culus isagoo ilaalinaya xoogga iyo xasilloonida lagama maarmaanka ah. Waa mid ku habboon qaadista mashiinnada culus, agabka dhismaha ama walxaha kale ee culus ee ku jira bakhaarrada, warshadaha iyo goobaha dhismaha.
Waxa silsiladdan ka dhigaya mid gaar ah waa u hoggaansanaanta heerka En818-8. Heerkan caalamiga ah wuxuu hubiyaa in silsiladuhu ay buuxiyaan heerarka tayada iyo badbaadada ugu sarreeya. Waxaa si gaar ah loogu talagalay in lagu qaado codsiyada waxaana la mariyaa baaritaanno adag si loo hubiyo isku hallayntiisa deegaannada ugu adag.
Xoogga sare ee silsiladda waa mid ka mid ah astaamaha ugu muhiimsan. Waxaa laga sameeyay dahaar gaar ah oo xoojiya xooggiisa guud iyo cimrigiisa, taasoo hubinaysa inay u adkeysan karto culaysyada ugu culus iyada oo aan wax u dhimayn badbaadada. Tani waxay ka dhigaysaa mid ku habboon hawlaha qaadista culus.
Codsiga
Badbaadadu had iyo jeer waa walaaca koowaad marka ay timaado qalabka qaadista, silsiladdanina ma niyad jabiso. Waxaa loogu talagalay sifooyin badbaado sida qabsatooyin badbaado si loo hubiyo in culaysku si ammaan ah ugu xiran yahay inta lagu jiro hawsha qaadista. Xoogga sare ee silsiladda iyo u hoggaansanaanta heerarka badbaadada ayaa ka dhigaya doorasho lagu kalsoonaan karo oo loogu talagalay shaqo kasta oo qaadis ah.
Marka laga soo tago xooggeeda sare iyo astaamaha badbaadada, silsiladdan kor u qaadista dahaarka ayaa sidoo kale leh iska caabin aad u fiican oo daxalka iyo iska caabin xirasho. Tani waxay ka dhigan tahay in silsiladdu ay sii waddo waxqabadkeeda xitaa jawi adag, taasoo ka dhigaysa maalgashi waara.
Isku darka cabbirka 12mm, u hoggaansanaanta En818-8, xoog sare, dhismaha dahaarka iyo adkeysi cajiib ah, silsiladdan qaadista ayaa ah doorashada ugu dambeysa ee dhammaan baahiyahaaga qaadista. Ku kalsoonow tayadeeda oo u ogolow inay hawlaha qaadistaada ka dhigto kuwo hufan oo ammaan ah.
