Cov kav hlau txuas ntxiv yog muaj nyob rau hauv engineering engineering. Feem ntau lawv tau siv thaum tso cov tso tsheb hlau luam septic, los ntawm kev lag luam thiab cov dej ntws hauv tsev. Vim lub fact tias xws li cov kav dej muaj ib tug loj txoj kab uas hla, lawv yog lug siv nyob rau hauv lub installation ntawm lub ntsiab collectors. Lawv yog indispensable nyob rau hauv kev npaj ntawm cua daj cua dub kav dej systems. Cov kav dej no tuaj yeem muaj qhov sib txawv, uas tso cai rau lawv siv thaum txhim kho ntau yam qauv xws li kev txhawb nqa, lub hauv paus thiab ntau ntxiv.

Ntau yam ntawm cov kav dej muaj zog ntxiv

Cov kav dej ua kom muaj zog yog cais raws li qee qhov nta. Yog li, lawv tuaj yeem ua rau tsis muaj zog. Cov khoom no yog siv los thauj cov kua los ntawm lub ntiajteb txawj nqus. Lawv yuav tsum tsis txhob siv rau hauv cov xwm txheej uas cuam tshuam qhov tseem ceebkua siab. Nyob rau tib lub sijhawm, cov kav dej zoo li no tuaj yeem tiv taus cov neeg kho tshuab siab, thiab tseem muaj lub zog zoo heev.

Qhov thib ob kev faib tawm ntawm cov kav dej txuas ntxiv yog cov khoom siv siab siv hauv kev teeb tsa ntawm txoj kev loj uas ua haujlwm ntawm cov khoom siv siab hauv daim ntawv ntawm kev siab sab hauv. Cov khoom no yog tsim raws li ib tug tshwj xeeb technology, uas muab rau cov kev siv ntawm crimping, uas txhim kho cov yam ntxwv zoo. Cov kav dej muaj zog muaj zog muaj cov phab ntsa loj, uas qee zaum nce mus txog 10% ntawm txoj kab nruab nrab sab hauv.

Tseem muaj cov kav dej rau lub hom phiaj tshwj xeeb, txoj kab uas hla ntawm qee zaum ncav cuag 2 m nrog qhov ntev ntawm 5 m. Cov khoom zoo li no tshwj xeeb tshaj yog ruaj. Raws li rau cov kav dej siab, lawv tuaj yeem muaj ib qho ntawm plaub qhov kev hloov pauv siab (5-20 cua), lawv tau siv rau cov kua dej uas tsis txawv ntawm qhov chaw nruj. Hauv kev tsim khoom, cov khoom lag luam nrog lub cheeb ntawm 40-160 cm yog qhov tshwj xeeb tshaj plaws.

Cov kav hlau txuas ntxiv tseem raug cais raws li qhov siab tshaj plaws tso qhov tob. Nws muaj peev xwm paub qhov txawv ntawm 3 pawg, txhua tus xav tias qhov deb ntawm lub ntiaj teb nyob rau hauv 2, 4 thiab 6 m.

Cov yeeb nkab no zoo li cov yas yas lossis cam khwb cia hlau kav. Txhawm rau ua kom cov khub ntawm cov khoom zoo li no airtight, cov ntsaws ruaj ruaj yuav tsum tau siv. Lub qhov (socket) cov khoom lag luam tau yooj yim rau nruab, uas ua rau lawv muaj ntau yam. Hauv qhov no, txoj kab uas hla ntawm cov pob qij txhaloj dua lub ntsiab txoj kab uas hla. Cov khoom zoo li no tuaj yeem ua rau lub siab lossis tsis muaj zog.

Txhawm rau kom nkag siab txog yam khoom nyob rau hauv pem hauv ntej ntawm koj - cov khoom siv txuas ntxiv uas tsis yog lub qhov hluav taws xob los yog lwm yam, koj yuav tsum nkag siab cov cim. Yog li, thawj tus lej uas tuaj yeem pom ntawm cov khoom tsis muaj zog nruab nrog lub qhov (socket) qhia qhov loj ntawm sab hauv, cov ntaub ntawv tau qhia hauv centimeters. Thaum qhov kev sib xyaw thib ob tuaj yeem siv los nkag siab tias qhov ntev ntawm cov yeeb nkab yog dab tsi, los ntawm txoj kev, nws tau qhia hauv decimeters. Tus lej kawg yog tus kabmob muaj peev xwm, uas qhia txog qhov tso cai rau kev teeb tsa qhov tob.

Yog tias cov yeeb nkab txuas txuas ntxiv tuaj yeem siv tau thaum tso cov txheej txheem siab, ces nws yuav muaj tsab ntawv TN. Yog tias muaj ib sab, ib leeg lossis chaw nres tsheb ntawm cov yeeb nkab, koj tuaj yeem pom cov cim TB, TP, TS, raws li. Tab sis cov khoom ntim khoom yuav muaj cov cim hauv qab no: TF, TFP, TBFP, TO, TE thiab lwm yam.

Cov pob zeb tsis muaj zog lossis cov kav dej siab muaj ntau qhov zoo, ua ntej ntawm cov khoom muaj zog thiab kev ntseeg siab ntawm cov khoom. Cov kev zoo no yog vim muaj kev siv tshuab tshwj xeeb. Nws yog centrifugal casting uas ua rau nws muaj peev xwm tau txais cov khoom zoo li no. Vibrocompression kuj tseem siv thaum tsim khoom. Ntxiv qhov zoo ntawm cov kav hlau txuas ntxiv yog tus nqi qis,uas tau piav qhia los ntawm tsis yog li cov nqi tsim khoom siab; nrog rau kev muaj peev xwm tiv taus qhov kub thiab txias. Tsis tas li ntawd, cov kav dej tuaj yeem ua haujlwm ntau dua qhov kub thiab txias. Lawv tuaj yeem siv rau hauv qhov chaw hnyav. Cov pob zeb tsis corrode thiab tsis rot, uas ua rau cov neeg siv khoom xaiv nws ntau dua piv rau cov hlau. Ntawm qhov zoo, cov kws tshaj lij qhia txog qhov zoo ntawm cov khoom siv hluav taws xob, qhov no yuav pab tshem tawm cov dej tsis zoo. Cov khoom zoo li no yuav kav ntev tshaj li ib nrab xyoo.

Cov pob zeb uas tsis muaj qhov siab thiab cov kav dej siab muaj qee qhov tsis zoo. Qee lub sij hawm rau lawv cov installation yuav tsum tau siv cov cuab yeej tshwj xeeb, uas ua rau kev ua haujlwm raug nqi ntau dua. Tsis tas li ntawd, rau cov kua dej kom zoo, qee qhov yuav tsum tau lubricate lub puab nto ntawm cov kav dej nrog ib qho tshwj xeeb muaj pes tsawg leeg, uas cuam tshuam cov nqi zog ntxiv.

GOST 6482-88

Cov qauv tsim khoom raug tswj hwm los ntawm GOST: cov kav dej txuas ntxiv raws li nws yuav tsum ua kom tau raws li cov yam ntxwv ntawm cov dej tsis kam, ntxiv rau, lawv yuav tsum tau ua kom muaj qhov siab ntawm hydrostatic hauv 0.05 MPa. Pob zeb yuav tsum resistant rau Frost. Tsis tas li ntawd, cov kav dej yuav tsum tau ua raws li cov pob zeb hnyav, npaj raws li GOST 26633, nws lub zog compressive yuav tsum sib npaug rau B25.

Lub zog compressive tau hais tuaj yeem hloov pauv, tab sis kev sib txawv uas dhau mus dhau ntawm GOST 13015.0 tsis raug tso cai. Cov dej tsis kam ntawm cov yeeb nkab phab ntsa yuav tsum ua raws li cov chav kawm W4. Kev nqus dej yuav tsum tsis pub tshaj 6% ntawm qhov hnyav. Hlau A-I thiab A-III (GOST 5781) tuaj yeem siv los ua lub tawb nqa khoom.

yam ntxwv ntawm cov kav hlau txuas ntxiv

Txhua tus yam ntxwv zoo ntawm cov kav dej txuas ntxiv yog tswj hwm los ntawm GOST hais, cov kav hlau txuas ntxiv uas tsis yog lub siab yuav tsum tsis txhob muaj cov kab nrib pleb ntawm phab ntsa, txwv tsis pub lawv siv tsis tau hauv kev ua haujlwm. Shrinkage tawg, qhov dav uas tsis pub tshaj 0.05 hli, ua raws li kev zam. Kev ua tiav kuj raug txiav txim los ntawm cov qauv. Yog li, cov kav dej uas cim TB, TSP, TBP, nrog rau TS yuav tsum tau muag thiab xa mus rau tus neeg yuav khoom nrog rau cov roj hmab sealing nplhaib. Kev ua tau zoo kuj tau txiav txim siab los ntawm qhov tseeb ntawm kev kos, uas qhia tau hais tias cov chaw tsim khoom kom meej meej ua raws li cov cai hauv GOST. Cov cim yuav tsum tau siv rau sab nrauv ntawm lub qhov (socket), lub cim tseem tuaj yeem nyob rau ntawm ib kawg ntawm cov kav dej seam.

Txoj kab uas hla ntawm cov kav dej txuas ntxiv tau qhia saum toj no thiab muaj ntau haiv neeg. Txhawm rau tso ib qho system, koj tuaj yeem xaiv cov khoom lag luam nrog qee yam tsis muaj. Tsis txhob xav tias yog tias thaum lub sij hawm installation koj yuav tsum tau siv nyiaj rau cov khoom hnyav, ces lub kaw lus yuav kim dua li cov kav dej uas ua los ntawm lwm cov khoom siv. Tom qab tag nrho, cov kav dej pob zeb tuaj yeem them nyiaj rau lawv tus kheej thaum lawv lub neej ua haujlwm yam tsis tas yuav kho lub sijhawm ntev.

Cov kav dej txuas ntxiv yog qhov yooj yim heev thaum tso, uas yog vim li cas lawv siv feem ntau, tab sisUa ntej kev teeb tsa tus kheej ntawm qhov system, koj yuav tsum sab laj nrog tus kws tshaj lij.
