Wareegayaasha: Cabbiraadda Socodka Fudud oo lagu Kalsoonaan karo ee Codsiyada Socodka Yar ilaa Dhexdhexaadka ah

Asalka naqshadaynta rotameter-ka waa mabda'a aagga isbeddelka leh, farsamo fudud oo wax ku ool ah oo isku xirta socodka dareeraha booska sabeyn la dhaqaajin karo. Qalabku wuxuu ka kooban yahay laba qaybood oo muhiim ah: tuubo si toosan loo rakibay oo wareegsan (oo si yar u ballaarinaysa hoos ilaa sare) iyo sabbayn (ama rotor) oo si dabacsan ugu habboon gudaha tuubada. Marka dareere (dareere ama gaas) uu ka soo galo tuubada hoose, wuxuu kor ugu qulqulaa hareeraha sabbaynta, isagoo abuuraya farqi cadaadis oo kor u qaadaya sabbaynta. Marka sabbaynta kor u kacdo, booska wareegsan ee u dhexeeya sabbaynta iyo derbiga gudaha ee tuubada ayaa kordha - taasoo yaraynaysa xawaaraha dareeraha iyo cadaadiska kor u kaca ee ka shaqeeya sabbaynta. Sabbaynta ugu dambeyntii waxay deggan tahay dherer u dhigma heerka socodka: heerarka socodka oo sarreeya waxay sabbaynta sare u qaadaan, halka heerarka socodka hoose ay u oggolaanayaan inay hoos u degaan. Miisaan la hagaajiyay oo ku yaal dibadda tuubada ayaa u oggolaanaya hawl wadeennada inay si toos ah u akhriyaan heerka socodka iyagoo ku salaynaya booska sabbaynta.

Mid ka mid ah faa'iidooyinka ugu muhiimsan ee rotameter-ka waa fududaantooda iyo kharashkooda hooseeya. Si ka duwan mitirrada socodka elektrolojiga ee u baahan koronto iyo elektrolojiyad adag, ama mitirrada socodka cufnaanta leh nidaamyada dareemayaasha ee adag, rotameter-ku ma laha qaybo dhaqaaqa marka laga reebo sabbeynta. Naqshaddan yar waxay u tarjumeysaa kharashyada wax soo saarka oo hooseeya, taasoo ka dhigaysa xulasho la awoodi karo oo loogu talagalay codsiyada miisaaniyadda ku salaysan - sida tijaabooyinka shaybaarka, qiyaasta kiimikada ee yar yar, ama daaweynta biyaha mugga yar. Intaa waxaa dheer, la'aantooda elektaroonigga ah waxay ka dhigan tahay inay ka shaqeyn karaan meelaha fog ama kuwa korontada ku yar, taasoo ah faa'iido muhiim ah oo loogu talagalay hawlaha la socodka goobta sida muunadda deegaanka ama nidaamyada biyaha miyiga.

Mitir-qaadayaasha rotameter-ka ayaa sidoo kale si fudud u iftiimaya rakibidda iyo isticmaalka. Uma baahna tuubooyin toosan (shuruudo caadi ah oo loogu talagalay mitirrada socodka marawaxadaha ama ultrasonic) waxaana lagu rakibi karaa si toosan iyadoo la dejinayo ugu yaraan—ku habboon meelaha cidhiidhiga ah ama nidaamyada jira halkaas oo dib-u-hagaajinta muuqaalku ay adag tahay. Akhrinta tooska ah ee muuqaalka ah waxay meesha ka saaraysaa baahida loo qabo bandhigyada dijitaalka ah ama diiwaan-galiyaha xogta, taasoo u oggolaanaysa hawl-wadeennada inay si kooban u hubiyaan heerarka socodka. Codsiyada u baahan la socodka joogtada ah, mitir-qaadayaal badan ayaa lagu qalabayn karaa qalab ikhtiyaari ah sida dareemayaasha birlabta ama dareemayaasha indhaha si loogu beddelo booska sabbaynta calaamad koronto (tusaale ahaan, 4-20mA) si loogu daro nidaamyada xakamaynta—isku-darka fududaanta awoodaha otomaatiga aasaasiga ah.

Awood kale oo muhiim ah waa kala duwanaanshahooda noocyada dareeraha. Rotameter-yadu waxay cabbiri karaan labadaba dareerayaasha (tusaale ahaan, biyaha, saliidaha, kiimikooyinka) iyo gaasaska (tusaale ahaan, hawada, nitrogen, gaaska dabiiciga ah), iyadoo naqshadaha loo habeeyey sifooyinka warbaahinta gaarka ah. Tusaale ahaan, rotameter-ka galaaska-tube waxaa loo isticmaalaa dareerayaasha cad, ee aan daxalka lahayn sida biyaha ama hawada, iyagoo bixinaya hufnaan si loo helo aragti sabbayn fudud. Rotameter-ka tuubada birta ah (badanaa laga sameeyay bir aan daxal lahayn ama naxaas) waxaa loogu talagalay dareerayaasha daxalka ah, gaasaska cadaadiska sare, ama codsiyada heerkulka sare - sida cabbiraadda dareeraha warshadaha ama uumiga. Waxyaabaha sabbaynta ah sidoo kale waa la habeyn karaa: PTFE waxay sabaysaa iska caabbinta kiimikada, birta aan daxal lahayn ee loogu talagalay isticmaalka cadaadiska sare, ama sabbaynta dhoobada ee dareerayaasha daxalka ah - hubinta iswaafajinta baahiyaha warshadaha ee kala duwan.

Codsiyada wax ku oolka ah, rotameter-ku waxay caddeeyaan qiimahooda warshadaha oo dhan. Shaybaarrada, waxaa loo isticmaalaa in lagu xakameeyo socodka gaasaska side ee chromatography-ga gaaska ama in lagu xakameeyo ku darista reagents-ka tijaabooyinka kiimikada - halkaas oo cabbiraadda saxda ah ee socodka hooseeya ay muhiim tahay. Wax soo saarka, waxay la socdaan socodka saliidaha saliidaynta ee mashiinnada ama dareeraha qaboojinta ee nidaamyada qalabka, iyagoo ka hortagaya waxyeelada qalabka ka timaadda saliidaynta hoos ama xad-dhaafka ah. Injineernimada deegaanka, waxay cabbiraan socodka kiimikooyinka ee warshadaha daaweynta biyaha wasakhda ah (tusaale ahaan, isku-xidhka ama jeermiska dila) ama socodka hawada ee nidaamyada la socodka qiiqa - taasoo taageerta u hoggaansanaanta heerarka sharciyeed.

In kasta oo rotameter-yadu ay leeyihiin xaddidaadyo—ma saxsana heerarka socodka sare (badanaa ka sarreeya 100 m³/h dareerayaasha) oo ay u nugul yihiin isbeddellada cufnaanta dareeraha ama viscosity—xooggoodu aad ayuu uga badan yahay cilladahaan codsiyada bartilmaameedkooda. Heerarka socodka yar ilaa dhexdhexaadka ah, halkaas oo fududaynta, kharashka, iyo isku halaynta la mudnaanta siiyo, rotameter-yadu weli lama barbar dhigi karo. Horumarka casriga ah, sida rotameter-ka caqliga leh ee leh miisaannada dijitaalka ah iyo isku xirnaanta wireless-ka, ayaa sii ballaariyay adeeggooda, taasoo u oggolaanaysa la socodka fog iyadoo la ilaalinayo faa'iidooyinkooda asaasiga ah.

Gunaanadkii, rotameter-ku waxay markhaati u yihiin awoodda injineernimada fudud. Waxay bixiyaan cabbir joogto ah oo la isku halleyn karo iyada oo aan lahayn kakanaanta ama kharashka tiknoolajiyada horumarsan, taasoo ka dhigaysa qalab aan lagama maarmaan u ah shaybaarrada, warshadaha, iyo hawlaha goobta adduunka oo dhan. Hadday tahay in loo isticmaalo kormeerka muuqaalka aasaasiga ah ama lagu daro nidaamyada otomaatiga ah, rotameter-ku waxay sii wadaan inay door muhiim ah ka ciyaaraan hubinta maaraynta dareeraha ee hufan, ammaan ah, iyo waafaqsanaanta warshadaha oo dhan.
