Sida O Rings uga saaraan khalafinta lensheedka kameraa rabaadka inta loo dhiso?

Kuwa robatiga aragti, dabbaqaadka lens-ka si toos ah ay kuwan dhaqanka aragga. Laakiin in badan muhandisiya wax baalitaa muhiim: ka baxaysa ee xidhka O‑rings kara farshaxaan safaha doorka. Si ay u guulayaan arrimahan, saddex qaybood lagama maarmaan laga socda—doorka taaj, heysta shaqada, iyo nidaamka saamiga.

Doorka Taaj: Doonista Xidhka Saxda

Caabuudka Fluorocarbon (FKM) ama Perfluoroelastomer (FFKM): Tani doorka ka siiya kala duwan yar marka la eego jahay jilbaha sare, khadiibka, iyo sharcigooda. FFKM wuxuu siinayaa istaabilid ka tiro leh kimikalka oo ka caawiya jahay gaarka ah.

PTFE‑Encapsulated O‑Rings: La taageeray siyaabaha u baahan in ay noqotid midhaar kale.

Ka hortag NBR ama VMQ: Caabuudka nitrile iyo silicone waxay ka siiyaan plasticizers ama biyihii silicone, oo kara farshaxaan safuhu doorka.

Ujejeninta Tashkha: Saafininta Hore iyo Hore

Kan la saafin, O-rings waa inay la dhawaaw oo ka saabsan ultrasonic, la soo dhaba oo ku dhawa IPA leh habboon sare, sidaas daraaddeed loo saaro agabta lacagta iyo xiininta. Qaar kasheeyayaasha heli doonaan O-rings oo hor intay u saaran meel saaf ah (cleanroom) waxaana asteeyeen si toos ah meelaha Class 100.

Qudhmin Jidhifka: Isolaatiyada Si Aaminimo

Soo dejin PTFE barriers (qalabka dhaadhax) u dhexeeya lens-ka iyo O-ring, ama isticmaal noocyo kala duwan oo isku raacaya exhaust chambers si loo ilaaliyo inay extractables ka fog tahay dhulka optikaal. Hata haddii laga daaqdaan yar yaraan, ma tixgali doono mooyaanka sawirka.

Hawl-galidda iyo Xasiloonida Xafiiska

Ilaali jeedka gaaban iyo xasiloonid sax ah si loo eegin in sealing materials (jicitaanka isku raaca) ay kor u kiciyaan ama cajiisanno. Dhawaajinta vaakuyma marwalba 80–120°C muddo 2–4 saa ay kor u qaadayaan in lagu bixiyo volatiles ee dambesha, taasoo ka dhisi doona in la hortagaa in ay kaluun tahay dhulka.

Xaalad dheemeed iyo Tallaabooyinka Laga Hogaamiyey

Si loo ilaaliyo in la ilaalado kaluunka lens-ka, waa in lagama filno hab mid ah:

Dooro astaamaha la xidhiidhaya (FKM ama FFKM, iyadoo isticmaalaya PTFE marka loo baahan yahay).

Isticmaal daryeel iyo taliyada horreeya si kalsoonid ah.

Ku dar noocyo ku xidhanta qoto dheer design-ka xidhidhka.

Beddelitaanka astaamaha kaliya, mana daryeelin ama aan si fiican ugu horumariyin, waxay dabadeed way keeni kartaa khaaska astaamaha, taas oo dhan u khasaaji kara naxaastimada iyo isku-darinta fudud ee nidaamka aragga robatiga.
