Indlela yokukhetha ifreyimu ye-silicone rubber heater

Ukusebenza neukuphathwa kokushisaizinhlelo zembula ukuthi ukukhethaisifudumezi esiguquguqukayoakukhona nje ukukhetha amandla angahleliwe kukhathalogi. Kumelwe uqale ngokuhlela ngokucophelela inkinga ozama ukuyixazulula ngaphambi kokubhekaishidi lokucacisa.

Chaza inkinga yokushisa

Ingabe uzama ukuvimbela ukujiya kwe-condensing kuphaneli yokulawula yangaphandle, ukugcina i-viscosity yoketshezi olusindayo esimweni sezulu esibandayo, noma ukulungisa izinto ezihlanganisiwe zezindiza? Njalo bala amandla adingekayo ngokusekelwe ekushiseni okuthile kwezinto, isisindo esishiswayo, kanye nesikhathi sokushisa esifiselekayo. Isibonelo, ukushisa i-drum yensimbi engamalitha angu-50 kawoyela kusuka ku-20°C kuya ku-80°C emahoreni amabili kudinga amandla okushisa ahluke kakhulu kunokugcina isikhwama esincane se-medical fluid esingu-500ml ku-37°C engaguquki. Kufanele futhi ucabangele ukulahlekelwa ukushisa kwemvelo. Kunconywa ukwengeza umkhawulo wokuphepha ongu-20% kuya ku-30% kumandla akho okuqonda ukuze ucabangele izindawo ezingafakwanga ugesi kanye nokulahlekelwa okuguqukayo ezindaweni ezinomoya opholile.

Khomba izimo zokusebenza ezibalulekile

Uma usuyazi ukuthi ufudumeza ini, bhekisisa indawo yokusebenza. Ingabe i-heater izovezwa ku-amakhemikhali anamandla, ukuhlanganisa umswakama, noma amazinga okushisa aphezulu kakhulu? Irabha ye-silicone ejwayelekile iphatha amazinga okushisa aphansi afinyelela ku--60°C futhi isebenza ngokuphepha afinyelela ku-232°C (450°F). Kodwa-ke, uma uhlelo lwakho lokusebenza lubona ukuchayeka okuqhubekayo kumakhemikhali abangela ukuvuvukala noma ludinga ukuhlanza okuphansi kwezinga le-IP66, kufanele ucacise isakhiwo se-silicone esijiyile noma isikhunta esiqinisiwe esiqiniswe nge-fiberglass. Ukucindezeleka komshini kungenye into ebalulekile. Uma i-heater iguquguquka njalo ngesikhathi sokusebenza, sungula irediyasi encane yokugoba—ngokuvamile ecishe ibe yi-1.5 inches yemiklamo ejwayelekile ye-wire-wound, noma eqinile kakhulu ye-foil eqoshiwe—ukuvimbela izakhi zangaphakathi ukuthi zingakhathali futhi ziqhekeke ngokuhamba kwesikhathi.

Yiziphi izici zesifudumezi senjoloba ye-silicone okufanele uziqhathanise

Ngemva kokuhlaziya imvelo kanye nenhloso yokusebenza, gxila ngqo ezimisweni eziqinile zeumshini wokushisa we-siliconeLesi yisigaba lapho ulinganisela khona ukusebenza okuhle kakhulu nemingcele yangempela yomzimba kanye nekagesi.
