Gukoresha Vortex Flowmeter mugupima Biogas

2020-10-17
Umuyoboro wa vortexishingiye ku ihame rya Karman. Igaragarira cyane cyane nka generator ya vortex idafite umurongo (umubiri wa bluff) ushyirwa mumazi atemba, kandi imirongo ibiri yimyanya isanzwe ikorwa muburyo butandukanye uhereye kumpande zombi za generator. Ikoreshwa cyane muri peteroli, imiti, metallurgjiya, ubushyuhe, imyenda, impapuro nizindi nganda zikoreshwa cyane, umwuka wuzuye, umwuka wuzuye hamwe na gaze rusange (ogisijeni, azote, hydrogène, gaze gasanzwe, gaze yamakara, nibindi), amazi na amazi (nk'amazi, lisansi, nibindi), Inzoga, benzene, nibindi) gupima no kugenzura.

Mubisanzwe, umuvuduko wa biyogazi ni muto, kandi bipimwa mugabanya diameter. Turashobora guhitamo ubwoko bubiri bwimiterere, ikarita ya flange nubwoko bwa flange. Mugihe duhitamo ubwoko, tugomba guhitamo gusobanukirwa nigipimo gito, umuvuduko rusange nigipimo kinini cya biyogazi. Imbuga nyinshi zapima biyogazi ntizifite ingufu, kuburyo dushobora guhitamo amashanyarazi akoreshwa na bateri. Niba umukoresha akeneye kumenyekanisha metero murugo, hashobora gukoreshwa vortex flometer ihuriweho, kandi ibimenyetso bisohoka biganisha kumurongo wuzuye ushyirwa mubyumba ukoresheje umugozi. Imiyoboro ya vortex irashobora kwerekana ako kanya gutembera no guhunika kwa biyogazi.
Mugihe ushyizeho vortex flowmeter yo gupima biyogazi, niba valve yashizwemo hafi yimbere yo kwishyiriraho, hanyuma valve igahora ifunguye kandi igafungwa, bizagira ingaruka zikomeye mubuzima bwa serivisi ya sensor. Biroroshye cyane guteza ibyangiritse burundu kuri sensor. Irinde kwishyiriraho imiyoboro miremire cyane. Nyuma yigihe kinini, kugabanuka kwa sensor bizatera byoroshye gufunga hagati ya sensor na flange. Niba ugomba kuyishiraho, ugomba gushiraho umuyoboro hejuru no kumanuka 2D ya sensor. Igikoresho cyo gufunga.

Kugirango umenye neza imikorere yuzuye, uburyo bwo gutembera kumuryango ntibugomba guhungabana. Uburebure bw'igice cyo hejuru kigororotse kigomba kuba hafi inshuro 15 z'umurambararo wa Dimetero (D), naho uburebure bw'igice cyo hasi kigomba kuba hafi inshuro 5 z'umurambararo (D). Iyo amajwi adafite umurongo wa vortex ashyizwe mumazi, imirongo ibiri ya vortices isanzwe ikorwa muburyo butandukanye uhereye kumpande zombi. Iyi vortex yitwa umuhanda wa Karman. Muburyo runaka bwo gutembera, inshuro ya vortex itandukanya iringaniza numuvuduko ugereranije umuvuduko mwinshi. Ubushobozi bwa capacitance probe cyangwa piezoelectric probe (detector) yashyizwe mumashanyarazi ya vortex hanyuma umuzenguruko ujyanye nawo ugashyirwaho kugirango ubashe kumenya ubushobozi.vortexcyangwa Piezoelectric detection ubwoko bwa vortex flow sensor.
