niaj hnub no feem ntau nyob hauv ntau lub tebchaws, suav nrog Russia, yog cov tshuab cua sov uas muaj cov khoom siv hluav taws xob ua kua. Qhov no yog ib tug complex ntawm cov cuab yeej - complex los yog yooj yim. Nyob rau hauv rooj plaub tom kawg, peb tab tom tham txog lub tswv yim qhib. Raws li ib feem ntawm cov tshuab no:
- chav boiler;
- tshav kub exchangers;
- khoom siv twj tso kua mis.
Tag nrho cov nodes yog interconnected los ntawm ib tug pipeline. Qhov zoo thiab cov yam ntxwv ntawm cov dej ntws yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom siv, yog li nws yog ib qho tseem ceeb heev uas yuav tau xaiv lub coolant kom raug, uas yuav tau tham hauv tsab xov xwm.
Yuav ua li cas yog lub coolant
Yog tias koj tab tom ntsib cov lus nug ntawm yuav ua li cas sau cov cua sov hauv ib lub tsev ntiag tug, ces koj yuav tsum paub seb lub coolant yuav tsum yog dab tsi. Cov kua dej zoo tagnrho rau lub luag haujlwm no tseem tsis tau tsim. Qhov no qhia tau hais tias txhua yam ntawm cov ntaub ntawv paub yog ua haujlwm nyob rau hauv tej yam kev mob.xwm txheej.
Ib qho tseem ceeb yog qhov kub thiab txias ntawm lub coolant, ua txhaum ntawm cov khoom muaj peev xwm hloov nws cov khoom, uas ua rau lub kaw lus kaw. Qhov tseeb coolant yuav tsum nqa cua sov ntau nyob rau hauv ib lub sij hawm luv luv, nws yuav tsum muaj ib tug tsawg viscosity, nws yuav tsum tsis txhob ua corrosion thiab yuav tsum tsis txhob ua phem rau cov inhabitants ntawm lub tsev. Ntawm lwm yam, thaum hloov cov cua sov, qhov kub poob yuav tsum tsawg, thiab tsawg viscosity yuav yog ib qho qhia txog kev siv ceev thiab nce hauv efficiency.
Yog tias koj tab tom xav txog cov lus nug ntawm yuav ua li cas sau cov cua sov hauv ib lub tsev ntiag tug, koj yuav tsum paub tias qhov no lossis qhov txias txias tuaj yeem ua rau xeb, vim li ntawd koj yuav ntsib kev txwv thaum xaiv cov txheej txheem thiab qhov chaw. ntawm qhov system.
User kev nyab xeeb
Yog tias peb tab tom tham txog kev nyab xeeb, ces lub coolant yuav tsum tsis txhob tshaj tus qauv rau toxicity, ignition kub, tib yam yuav tsum tau ua rau cov kua vapor. Ib qho tseem ceeb thaum xaiv yog tus nqi. Tus nqi yuav tsum qis, txwv tsis pub tus neeg siv khoom yuav tsum siv lub tshuab ua kom txias kom ntev ntev yam tsis hloov nws.
Nyob zoo ib tsoom niam txiv kwv tij neej tsa sawv daws.
Ua ntej koj txiav txim siab yuav ua li cas sau cov cua sov hauv ib lub tsev ntiag tug, koj yuav tsum xav txog cov kev daws teeb meem feem ntauqhov teeb meem no. Ib tug ntawm lawv yog dej, qhov zoo ntawm cov uas tau hais nyob rau hauv lub siab tshaj plaws tshav kub muaj peev xwm ntawm tag nrho cov kua, raws li zoo raws li ib tug tsawg ntom. Yog li, ib kilogram ntawm dej, qhov kub ntawm 90 ° C, yuav txias mus rau 70 ° C, thaum tso cua sov nyob rau hauv tus nqi ntawm 20 kcal.
Thaum txiav txim siab dab tsi los ncuav rau hauv cov cua sov ntawm lub tsev ntiag tug nrog lub tshuab hluav taws xob, koj tuaj yeem xav txog qhov kev xaiv dej, uas txawv ntawm ib puag ncig thiab toxicological khoom los ntawm cov khoom siv hluavtaws. Nws muaj kev nyab xeeb rau tib neeg, thiab yog tias muaj dej ntws tawm, nws yuav tsis ua teeb meem ntxiv. Xws li ib tug coolant tuaj yeem yooj yim tau, nrog rau qhov tsis muaj ntim, sau lub kaw lus nrog tus nqi tsim nyog. Lub coolant no tsis muaj kev sib tw ntawm tus nqi, koj tsuas yog nrhiav tsis tau cov kua uas pheej yig dua.
rau kev siv
Yog tias koj tab tom ntsib txoj haujlwm ntawm yuav ua li cas sau cov cua sov hauv ib lub tsev ntiag tug, koj yuav tsum xav txog tias cov dej hauv nws li niaj zaus yuav tsum tsis txhob siv, vim nws muaj cov ntsev thiab oxygen. Thaum lub sij hawm, los ntawm xws li additives, nplai yuav nyob rau hauv lub sab hauv ntawm lub cua sov system thiab corrosion yuav tshwm sim. Thiab txhawm rau kom lub kaw lus ua haujlwm tsis muaj kev cuam tshuam, cov kua yuav tsum tau muag ua ntej siv.
Yuav ua li cas, koj tuaj yeem siv ib txoj hauv kev uas twb muaj lawm. Nws tuaj yeem yog thermal lossis chemical technology. Nyob rau hauv thawj rooj plaub, cov txheej txheem yog raws li boiling. Dej yuav tsum tau muab tso rau hauv ib lub tank hlau uas nws yuav tsum tau rhuab. Thaum boiling, carbon dioxide yuav raug tshem tawm, thiab ntsev yuav muab tso rau hauv qab ntawm lub nkoj. Cov sib xyaw ua ke ntawm magnesium thiab calcium tseem nyob hauv dej. Cov txheej txheem tshuaj ua haujlwm ntawm tus nqi ntawm cov tshuaj reagents. Nrog kev pab ntawm soda tshauv, sodium orthophosphate thiab hydrated txiv qaub, cov ntsev ua insoluble thiab precipitate, dhau los ua precipitate. Kev pom tom ntej yuav tshem tawm cov seem ntawm cov khoom tsis zoo.
Vim li cas coob tus tsis kam dej
Yog tias koj ntsib cov lus nug ntawm dab tsi yuav tsum tau sau rau hauv cov cua sov ntawm lub tsev ntiag tug rau lub caij ntuj no, feem ntau koj yuav tsum tso dej. Nyob rau hauv cov ntaub ntawv no, xws li ib tug parameter ntawm coolant raws li lub kub tswj plays lub luag hauj lwm tseem ceeb. Yog tias qhov kub hauv lub tsev poob qis dua 0 ° C, cov kua yuav khov, thiab qhov no yuav ua rau cov cua sov ua kom tawg.
Siv tshuaj tiv thaiv kab mob
Thaum qhov txias tuaj, qhov hu ua tsis khov yuav cuam tshuam, uas yog cov kua tshwj xeeb rau cov cua sov. Yog tias cov kav dej tau ntim nrog cov dej txias zoo li no, txawm tias qhov kub thiab txias poob mus rau qhov tseem ceeb, lawv yuav tsis tawg, uas yog qhov tseem ceeb heev rau vaj tse uas siv tsis tu ncua. Nyob rau hauv cov ntaub ntawv no, antifreeze yog siv los ua ib lub zog nqa, uas yog tsim los ua hauj lwm nyob rau hauv ib tug dav kub ntau yam ntawm -30 mus -65 ° C.
Thaum cov lus nug tshwm sim ntawm dab tsi los sau rau hauv cov cua sov ntawm lub tsev ntiag tugNyob rau lub caij ntuj no, nws tsim nyog them nqi rau qhov kev xaiv no, uas tsis tawv, tab sis tau txais kev hloov pauv ntawm cov gel hom thaum kub poob qis dua 0 ° C.
Rov qab mus rau nws lub xeev qub, cov tshuaj tiv thaiv yuav tsis plam nws cov khoom qub thiab yuav tsis ua rau muaj kev hem thawj rau lub tshav kub. Txhawm rau tshem tawm foci ntawm corrosion lossis nplai, cov tuam txhab siv cov khoom siv ntxiv hauv daim ntawv tshwj xeeb inhibitors. Ua tsaug rau qhov no, lub sijhawm ua haujlwm ntawm lub tshuab cua sov tuaj yeem txuas ntxiv los ntawm ntau xyoo.
Yam yuav tsum tau xav txog ua ntej xaiv tshuaj tiv thaiv
Yog tias koj tseem tsis tuaj yeem txiav txim siab seb yuav ua li cas rau hauv cov cua sov ntawm lub tsev ntiag tug - dej lossis tshuaj tiv thaiv kab mob, ces koj yuav tsum coj mus rau hauv tus account lub sijhawm kawg ntawm cov kev xaiv uas tau teev tseg yog tsim los rau ob peb lub caij ua haujlwm.. Nws tuaj yeem yog 5 xyoos, lossis ntau dua, 10 lub caij. Tom qab lub sij hawm no, lub coolant ntim yuav tsum tau hloov. Cov neeg tsim khoom feem ntau pom zoo kom siv tshuaj tiv thaiv kab mob rau li 3 xyoos.
Qhov dej txias twg haum rau txhuas radiators
Ethyl cawv raws li qhov txias tuaj yeem siv rau lub tshuab hluav taws xob txhuas, uas tuaj yeem npaj tau yooj yim los ntawm koj tus kheej. Thaum kawg, nws yuav muaj peev xwm tau txais cov kua uas yuav yog cov khoom sib tov tsis khov, uas suav nrog ethyl cawv thiab dej distilled. Cov kua no yuav muaj viscosity me ntsis dua li cov dej ib txwm muaj. Txawm li cas los xij, daim duab no yuav qis dua ntawm lub Hoobkasantifreeze.
Lub fluidity ntawm cov kua no tsawg dua piv rau cov tshuaj tiv thaiv kab mob, uas ua rau nws muaj peev xwm tsis quav ntsej txog qhov yuav tsum tau ua kom nruj ntawm kev sib txuas hauv Circuit Court. Xws li cov kua yuav tsis tuaj yeem ua rau cov roj hmab ntsaws ruaj ruaj ntawm lub kaw lus. Thaum cov neeg siv khoom xav txog cov lus nug ntawm yuav ua li cas sau cov cua sov ntawm lub tsev ntiag tug nrog aluminium radiators, lawv sim xaiv cov kev sib xyaw ua ke, vim lawv muaj ib qho txiaj ntsig zoo dua lwm txoj kev xaiv, uas yog lub peev xwm los siv cov khoom sib xyaw rau cov hlau radiators.. Qhov no yog vim qhov tseeb tias cawv yuav tiv thaiv kev txhim kho corrosion, thiab qhov no yog qhov tseem ceeb rau cov kab ke uas nws qhov kev puas tsuaj tuaj yeem ua rau muaj qhov tsis zoo. Hauv qhov no, nws raug nquahu kom siv dej tawv, uas, ua ke nrog cawv, yuav tiv thaiv kev tsim cov nplai ntawm cov khoom siv sab hauv. Cov nag lossis daus yuav tsim rau hauv daim ntawv thiab tuaj yeem muab pov tseg tau yooj yim nrog kev tiv thaiv ntxuav.
Zaj lus
Ua ntej xaiv cov tshuaj tiv thaiv kab mob, nws raug nquahu kom ua tib zoo saib xyuas qhov tseeb tias cov tshuaj no tuaj yeem muaj lub hom phiaj sib txawv. Ib txhia yog npaj rau tsheb, lwm tus yog rau cov cua sov tshuab. Lawv txawv nyob rau hauv muaj pes tsawg leeg, yog li lawv tsis tuaj yeem sib xyaw. Cov khoom siv raw tuaj yeem yog ethylene glycol lossis propylene glycol. Heev feem ntau, niaj hnub craftsmen nyob rau hauv tsev txiav txim siab dab tsi ncuav rau hauv lub cua sov system ntawm ib tug private lub tsev. Antifreeze, uas tseem hu ua antifreeze, yuav txawv nyob rau hauv viscosity, freezing point thiab nqe qeb. Cia li nco ntsoov.
