Xaiv qhov tseeb expansion tank

Cov cua kub system ntawm tej tsev yog ib qhov nqi ntawm coolant. Ntawm cov hoob kawm nyob rau hauv physics, txij li thaum high school peb txhua tus yeej paub hais tias thaum cua kub kua kom nyob rau hauv volume, expanding nyob rau tib lub sij hawm. Qhov no ntxiv volume yuav tsum tau muab tso rau qhov chaw, txwv tsis pub tus system yuav ib yam dab tsi zoo li ib tug yeeb nkab foob pob. Nyob rau hauv kev txiav txim kom tsis txhob muaj txoj kev pheej hmoo ntawm tawg, siv ib tug tshwj xeeb expansion tank, uas poob mus rau lub resulting tshaj kua.

Loj haum expansion tank yuav tsum tau xaiv nyob rau hauv txhua rooj plaub zuj zus. Nws yuav yog nyob ntawm seb tus nqi tag nrho ntawm coolant mus rau ib los yog lwm system.

Nyob rau hauv niaj hnub combi boilers xws peev xwm ua tau rau hauv cov ntaub ntawv. Nws tsis sai li sai pom tus tswv, vim hais tias nws yog muab zais nyob rau hauv lub hlau casing. Lub volume ntawm lub surge tank nyob rau hauv xws boilers nce mus txog ib nrab ntawm 12 liters. Producers lawv tus kheej paub kwv yees loj ntawm lub chav tsev, uas yog xam rau tus ntaus ntawv, ces lawv muab lawv expansion tank. Nws muaj ib tug tej yam cia qhov chaw rau qhov zuj zus ntim ntawm cov kua. Expansion tank rau cua sov, ua-nyob rau hauv cov phab ntsa mounted boiler yuav tsam los yog hloov nrog ntau volume, muaj peev xwm qauv.

hom ntawm pab kiag li lawm

1. Yav tas los, feem ntau cov qauv yog tus expansion tank qhib hom cua sov tshuab. Lub hauv paus ntsiab lus ntawm cov lag luam yog zoo li nws cov kev txiav txim ntawm lub lauj kaub nrog ib tug hau los yog ib tug welded yeeb nkab muaj peev xwm. Cov seem dej ntws los ntawm nws nyob rau tsa kub, thiab ces, nyob rau cua txias lub coolant, piv txwv li, thaum lub boiler yog tawm, nws mus rov qab mus rau hauv lub system. Feem ntau nyob rau hauv qhib tso tsheb hlau luam phwj tso - lwm cov yeeb nkab rau saum. By tshaj coolant therein yog muab tshem tawm (feem ntau yog mus rau hauv cov lim dej). tswv feem ntau raug nqi txawm tsis muaj tus expansion tank, teem lub "phwj" ntawm lub system ntawm lub siab tshaj plaws taw tes. Koj yuav tsum ua raws li nyob rau hauv cov ntaub ntawv no, mus rau lub kav cia ib tug txaus mov ntawm cov dej. Ib tug disadvantage ntawm xws li ib tug qauv yog xeb ntawm lub tank thiab ib tug loj evaporation ntawm coolant nyob rau hauv kev sib cuag nrog cua. Qhov kom zoo dua ntawm no hom ntawm tso tsheb hlau luam yog ib tug yooj yim tsim thiab tus nqi qis installation.

2. Tam sim no cov qauv uas ntsuas nrog sideburns kaw. Xws li ib tug expansion tank muaj ob cua kub kab noj hniav. Ib tug ntawm lawv yog npaj rau cov kev ntawm coolant, thiab lub thib ob muaj huab cua los yog nitrogen. Split kab noj hniav tshwj xeeb membrane uas yog ncav us txog nyob rau hauv kev txo los sis nce nyob rau hauv volume coolant. Lub siab nyob rau hauv tag nrho cov system tshua zoo unchanged. Xws li ib tug expansion tank muaj tej yam zoo - lub coolant tsis qhuav, tsis tas muab ib tug tank nyob rau sab saum toj ntawm lub system. Qhov tsis zoo ntawm no tsim yog tus nqi siab thiab ib tug loj npaum li cas, vim hais tias polbaka yuav siv sij hawm tank ntawm roj.

Yuav kom xam pom nyiaj ntawm qhov yuav tsum tau expansion tank, muab tus nqi ntawm cov coolant 0.08. Yog li, rau cov system 100 l coolant expansion tank xav tau rau cua sov rau yam tsawg kawg 8 liters.
