Lub tshuab foob yog ib qho kev sib dhos siv los kaw cov ntu ntawm lub twj tso kua mis qhov twg lub taub hau hla lub hau. Kev ceev txaus yog tsim los ntawm kev nias muaj zog ntawm qhov chaw ntawm ob lub ntsiab lus - tig thiab ib qho chaw ruaj khov. Cov khoom yuav tsum muaj siab precision, nws yog tiav los ntawm lapping thiab sib tsoo.

Cov khoom siv foob rau cov twj qhuav yam tiv thaiv cov kua nkag mus rau qhov chaw nyob ib puag ncig, thiab rau cov twj submersible lawv tsis tso dej nkag mus rau lub cev muaj zog, yog li zam kev luv luv. Txhawm rau kom qhov tseeb, ob lub ntsaws ruaj ruaj nyob ntawm ib tus ncej siv lub dielectric (roj lossis txias huab cua).

Lub kaw lus sib dhos tuaj yeem sib npaug, cartridge lossis cais tsim. Cov kua dej siab, hom kua dej thiab qhov kub thiab txias cuam tshuam rau cov khoom siv tawv lossis mos siv. Aluminium oxide, impregnated graphite, thiab carbide tau siv dav. Roj hmab tuaj yeem siv los ua lub foob thib ob.

Yuav ua li cas txuas lub neej kev pabcuam

Nws tsim nyog sau cia tias cov ntsiab lus no raug hnav sai thiab nkag siab rau ib puag ncig, tab sis txawm li cas los xij, lawv yog qhov tseeb tshaj plaws. Feem ntau ntawm cov teeb meem hauv kev ua haujlwm ntawm cov twj tso kua mis yog txuam nrog kev tawg ntawm cov khoom siv npe. Lub neej kev pabcuam raug txo qis vim muaj ntau yam, piv txwv li, vim yog qhov ua haujlwm ntawm cov khoom abrasive lossis qhov kub siab. Nws kuj raug cuam tshuam los ntawm kev siv tsis raug. Txhawm rau kom lub tshuab foob tau ntev dua, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov khoom sib xyaw uas haum rau cov dej num.

Emulsions thiab roj tsis haum rau roj hmab vim nws tsis tiv taus cov khoom ua kom zoo. Hauv qhov no, Viton yog siv rau kev sib khi. Qhuav khiav, uas ua rau overheating, yuav ua rau lub cuab yeej puas. Yuav tsum muaj lub tshuab ua pa los ntawm cov twj tso kua mis tso.

Kev teeb tsa kom zoo ntawm automation yog qhov tseem ceeb tshwj xeeb. Kuj tseem muaj qhov ua tau raws li qhov yuav tsum tau ua, uas cov dav hlau sib txuas ua ke tom qab lub sijhawm poob los yog cov roj hmab yog soldered rau ntawm ncej. Tig lub ncej qee zaus kom tiv thaiv tsis txhob lo.

ob lub foob

Hom, khoom siv thiab tsim ntawm lub foob yog nyob ntawm cov xwm txheej hauv kev ua haujlwm thiab cov yam ntxwv ntawm cov twj tso kua mis. Tib lub foob yog siv rau cov kua dej uas tsis tawg thiab tawg, nrog rau cov khoom tawg ntawm pawg T1, T2 thiab T3.

Ob lub foob siv rau cov kua dej nyob qhov twgib leeg yuav tsis ua haujlwm. Cov no yog ib puag ncig muaj kev phom sij, tshuaj lom, caustic lossis tshuaj abrasive. Nws yog ib qho tsim nyog sau cia tias nyob rau hauv kev ua haujlwm nyuaj, qhov kev tsim no kav tsib zaug ntev dua li lwm tus. Tsis tas li ntawd, nws cov hlau sab hauv yog resistant rau ib puag ncig influences, thiab thermosetting, viscous masses sai sai kaw yam tsis muaj nqi ntxiv.

Raws li GOST R 52743-2007, ob lub tshuab foob siv rau cov kua tawg ntawm qeb T4. Kev puas tsuaj emission tus nqi, kev siv lub sij hawm thiab tus nqi ntawm ob lub sealing ua qhov kev xaiv zaum kawg.

Ntawm cov kev cai dav dav rau cov khoom siv foob, nws tsim nyog sau cia kev sib raug zoo nrog kev tsaws thiab tag nrho qhov ntev ntawm cov twj. Cov qauv dav dav yuav tsum muab rau hom kev ua haujlwm dhau los ntawm qhov tsis tshua muaj siab ntawm qhov loj hauv lub tank piv nrog qhov nruab nrab raug kaw. Kev siv ob lub foob tshem tawm qhov muaj peev xwm ntawm to. Cov khoom siv rau lub cev cov ntsiab lus yuav tsum ua raws li cov yam ntxwv thev naus laus zis ntawm cov kua kom hloov mus.

Gas barrier

Zoo ib yam li ob lub foob foob, siv cov roj inert ua kom txias thiab lubricating tus neeg sawv cev, thiab es tsis txhob siv lub dav hlau dej los yog cov dej txias. Cov txheej txheem no tau tsim los ntawm qhov tseeb tias qee qhov kev sib xyaw ua ke uas siv yav dhau los tsis tuaj yeem siv tau vim tsis ua raws li cov qauv tshiab emission.

Seals raws li kev siv roj barrierhuab cua tsis zoo los yog nitrogen los tiv thaiv cov khoom los ntawm kev khiav mus rau ib puag ncig thiab ua raws li cov qauv tsim tawm. Nyob rau hauv cov xwm txheej uas yuav tsum tau muaj kev ntseeg siab, los yog thaum thauj khoom tsim kev puas tsuaj los yog tshuaj lom, yuav tsum tau siv roj ob chav thaiv kev tsim.

Los ntawm txoj kev, tus nqi nruab nrab (cov tshuab foob nrog cov roj barrier) yog kwv yees li 2 txhiab rubles.

Tandem

Kev tswj hwm ib puag ncig thiab kev noj qab haus huv tswj hwm kev siv cov khoom siv rau cov khoom siv xws li hydrocarbons, carbon monoxide, vinyl chlorides thiab ntau yam ntawm lwm cov tshuaj carcinogenic lossis volatile compounds.

Cov cuab yeej no pab tiv thaiv cov dej khov ntawm lub teeb hydrocarbons thiab cov kua dej, uas yog tus cwj pwm los ntawm qhov kub thiab txias hauv qab qhov dej khov. Propanol thiab methanol yog cov piv txwv ntawm cov qauv uas muaj cov yam ntxwv tsis zoo. Tsis tas li ntawd, tandem nce qib ntawm kev ntseeg tau. Thaum cov qauv ua tsis tau zoo, cov khoom siv sab nraud yuav siv sij hawm saib xyuas cov haujlwm.

Tsis muaj pusher

Txhawm rau tswj kev sib cuag ntawm cov dav hlau sib khi, nws yog qhov tsis xav kom txav cov qauv raws lub tes tsho lossis ncej. Ntawm cov txiaj ntsig tseem ceeb, nws tsim nyog hais txog qhov ua tau zoo tshaj qhov kub ntawm qhov dav thiab qhov tsis xav tau kev sib khi ntxiv.

Qhov downside yog hla ntu hloov kho rau kev siv lub luag haujlwm hnyav.

Pusher

txhawm rau xyuas kom muaj kev sib cuag ntawm qhov chaw ntawm cov nodes, nws yuav tsum tau txuas lub tshuab hluav taws xob thib ob uas txav raws lub axis ntawm lub tes tsho lossis ncej. Vim yog cov cuab yeej no, kev puas tsuaj ntawm lub dav hlau pem hauv ntej ntawm lub cuab yeej tau them nyiaj. Nws qhov zoo muaj xws li tus nqi qis thiab muaj ntau yam ntawm cov pushers, nthuav tawm hauv khw muag khoom hauv ntau qhov kev teeb tsa thiab ntau thiab tsawg. Tab sis nws yuav tsum tau muab sau tseg tias nws tuaj yeem ua rau muaj kev puas tsuaj rau lub tes tsho thiab hloov chaw ntawm lub foob thib ob.

Cov khoom siv sib npaug

Kev ntsuas qhov sib npaug suav nrog qhov kev hloov pauv yooj yim uas txo cov hydraulic quab yuam uas kaw lub tshuab ntsaws ruaj ruaj. Kev sib xyaw ua ke yog qhov txawv ntawm qhov kev tso tawm ntawm cov cua sov tsawg, tsis tshua muaj kev ntxhov siab ntawm qhov chaw sib khi thiab nce siab. Qhov no ua rau lawv xaiv qhov zoo tshaj plaws rau kev thauj cov formulations nrog siab vapor siab thiab lubricity tsis zoo.

tsis sib npaug

Lawv muaj cavitation zoo thiab kev sib haum xeeb ruaj khov, tsis tshua muaj dej thiab tus nqi qis. Ib theem siab tsawg txaus yog qhov tsis zoo ntawm cov qauv tsim. Yog hais tias qhov teeb tsa siab txwv ntawm qhov tshwm sim ntawm qhov kev txhawb nqa uas ua rau ntawm cov khoom sib khi yog dhau, cov yeeb yaj kiab nyob nruab nrab ntawm qhov chaw raug nyem tawm, thiab kev ua haujlwm yuav qhuav.

Standard

Ib qho piv txwv yog Grundfos - kawgcov ntsaws ruaj ruaj uas yuav tsum tau mounting thiab sib dhos ntawm lub tes tsho los yog ncej. Txawm hais tias txoj kev teeb tsa yooj yim ntawm lub cuab yeej, txo cov nqi kho mob tam sim no yog qhov tseem ceeb, ua rau kev tsim cov cartridge ntau dua.

Internal ib leeg

Hom Wilo tshuab foob yog nrov tshaj plaws. Muaj qhov muaj peev xwm hloov tau yooj yim los ua ib qho kev tsis sib haum rau cov dej ntws tawm, sib npaug kom tiv taus qhov siab ntawm ib puag ncig. Pom zoo kom siv nrog cov dej ntxhib ntxhib thiab tsis nruj nrog lubricity txaus.

Cartridge

qeb no suav nrog cov tshuab ntsaws ruaj ruaj rau cov twj tso rau ntawm lub tes tsho, suav nrog lub tes tsho ncej thiab lub thawv ntim khoom ntim, uas muaj qhov nruj haum rau lub ncej. Lawv lub ntsiab kom zoo dua yog tias tsis tas yuav siv cov khoom sib txuas rau lawv lub installation. Cov qauv tsim no txo qhov ua yuam kev thaum lub sijhawm teeb tsa thiab txo cov nqi khiav haujlwm.

External single

Lub tshuab foob no dhau los ua tus nqi zoo rau cov hlau kim uas xav tau los muab kev tiv thaiv corrosion rau cov ntsaws ruaj ruaj, muab cov kua nplaum muaj zog heev. Muaj tseeb tiag, nws tsim nyog sau cia ntawm qhov tsis zoo ntawm qhov cuam tshuam rau hydraulic siab thiab cuam tshuam ntawm kev poob siab, uas yog vim li cas cov ntsaws ruaj ruaj ntawm hom no muaj qhov txwv me me.
