Vim li cas thiaj muaj ntau yam sib txawv ntawm cov khoom siv hydraulic?

Txawm hais tias tej zaum yuav muaj ntau pua yog tias tsis yog ntau txhiab tus hydraulic fittings thiab connectors, lawv txhua tus boil mus raupeb hom pib. Peb hom no yog hlau foob, mos foob, los yog tapered xov connectors. Tsis muaj teeb meem dab tsi ntawm cov khoom fittings koj li, nws yuav tsum ua kom tau raws li ob yam xwm txheej: nws yuav tsum kaw thiab nws yuav tsum tuav.

Qee qhov xwm txheej, tib lub tshuab tuaj yeem ua tiav ob txoj haujlwm, thiab lwm qhov, ob qhov sib txawv ntawm tib lub tshuab yuav ua haujlwm tsim nyog. Tapered yeeb nkab connectors raug txiav rau ntawm ib tug taper nrog ib tug yeeb nkab txoj kab uas hla, thiab nws hloov raws tag nrho cov threaded ib feem ntawm ib tug yeeb nkab, thiaj li yuav ua rau cov kev twb kev txuas tighter. Cov hom fittings no yuav tsum muaj lub sealer, yog li koj tuaj yeem paub tseeb tias yuav tsis muaj qhov xau nyob ib puag ncig qhov haum, thiab qhov no feem ntau ua tiav nrog cov tshuaj sealant lossis daim kab xev sealant.

Txawm hais tias nws yuav nyuaj rau kev taw qhia cov yeeb nkab kab xev kom raug, nws tseem ceeb heev uas yuav tsum ua li ntawd, vim tias lub foob tsis zoo yuav ua rau muaj dej xau thaum siv siab. Yog tias muaj qhov tsis zoo rau kev sib txuas ntawm cov yeeb nkab, nws yog qhov uas lawv yuav tsum tau soldered los yog welded rau cov raj thaum ua kev sib txuas.

Hlau foob connectors tau tsim loj heev los muab lwm txoj hauv kevtapered yeeb nkab xovntau yam. Hom no siv cov xov tapered ua ke nrog lub ntsej muag machined, los muab lub foob muaj peev xwm tuav tau qhov raug mob siab cuam tshuam nrog hydraulics. Cov xov pab ua kom tiav lub zog tuav, thaum lub sealing yog tswj los ntawm lub ntsej muag machined.

Cov hom no yooj yim dua rau kev taw qhia ntau dua li cov khoom sib txuas, thiab lawv feem ntau muab lub foob zoo dua, tsis tas yuav muaj lwm yam sealant ntxiv. Txawm li cas los xij, lawv tseem xav tau vuam lossis vuam rau lub raj. Cov foob mos yog tej zaum yog hom nrov tshaj plaws uas siv niaj hnub no, thiab cov no muaj lub foob elastomeric uas tiv thaiv kom tsis txhob muaj kev kub ntxhov.

Ib qho ntawm qhov zoo tshaj plaws rau kev siv cov ntsaws ruaj ruaj yog tias lawv tuaj yeem ntsia tau sai heev, thiab qhov no yog qhov muaj txiaj ntsig zoo hauv cov ntawv thov kev lag luam. Lawv kuj muaj peev xwm tiv taus kev co hnyav uas ntau lub tshuab raug, yog li lawv tsis tawg ze li ntau zaus.

QHOV CHAW UA HAUJ LWM HAUJ LWM yog dab tsi?

Covfeem ntau homntawm fittings yog teev hauv qab no, nrog rau cov lus piav qhia luv luv ntawm txhua tus:

• NPT/NPTF- feem ntau siv hom xov nyob rau hauv North America, cov no yog recognizable los ntawm tapered puab txoj kab uas hla thiab lub tapered txheej txoj kab uas hla, ua tus haum self-sealing.

• BSPT (JIS-PT)- feem ntau hu ua British Thread Type, cov no yog cov qauv fittings uas tau txais kev pom zoo thoob ntiaj teb rau kev sib khi cov yeeb nkab kawg thiab ua kev sib txuas.

• Metric Taper- feem ntau siv xov hom nyob rau hauv cov teb chaws Europe, nws yog paub zoo rau nws cov leej cylindrical puab thiab sab diameters.

• SAE Ncaj Xov- hom xov zoo heev thiab siv tau dua tshiab, cov no muaj kev sib khi zoo heev vim yog 90-durometer O-Rings.

• TS EN ISO 6149 Cov- muaj metric ncaj xov O-Ring chaw nres nkoj, uas muaj txiaj ntsig zoo rau kev kuaj xyuas cov ntawv thov.

• JIS-B2351- Feem ntau siv los ua hose adapters rau cov khoom tsim hauv Nyiv lossis Kaus Lim Kauslim, cov no feem ntau muaj BSP threads

• DIN Metric- DIN yog German Industrial Standard, thiab cov no yog nrov thoob plaws lub teb chaws Yelemees thiab ntau ntawm cov teb chaws Europe

• BSPP (JIS-PF)- JIS stands rau Japanese Industrial Standards, thiab cov BSPP connectors ua raws li tus qauv British xov qhov ntev

• 4- Bolt Flange- muaj ntau yam sib txawv ntawm 4-bolt flange xaiv, xws li rau lub luag haujlwm ib txwm lossis lub luag haujlwm hnyav

YUAV UA LI CAS YUAV TSUM TAU HYDRAULIC CONNECTIONS?

Muab qhov tseeb tiascov cuab yeej siv tshuabthiabtshuabyog tsim thiab tsim los ntawm manufacturers thoob plaws lub ntiaj teb no, nws tsis yog qhov xav tsis thoob tias muaj ntau ntau hom fittings thiab adapters. Cov khoom siv loj loj no ua rau siv ntau txoj kev sib khi sib txawv thiab cov ntaub ntawv xov, thiab thaum ntau qhov no yuav zoo li zoo ib yam lossis tsawg kawg zoo sib xws, nws tsis yog qhov nyuaj kom paub tseeb tias hom twg tiag tiag yog. Feem ntau hom fittings tau qhia hauv qab no, thiab cov no yuav raug siv nyob rau hauv ib lub teb chaws ntawm lub ntiaj teb no, los yog los ntawm manufacturers nyob txhua qhov chaw ntawm ib tug neeg sab av loj.

Txhawm rau txiav txim siab hom koj ua haujlwm tiag tiag nrog, muaj cov txheej txheem plaub-kauj ruam yooj yim koom nrog. Ua ntej tshaj plaws, koj yuav tsum txiav txim siab seb nws puas yog hom khoom ruaj khov lossis rov siv tau, thiab cov khoom siv ruaj khov yuav yog cov uas raug crimped. Cov no yooj yim dua thiab nrawm dua los txuas dua li cov khoom siv rov qab siv tau, thiab qhov ntawd ua rau lawv zoo tagnrho rau kev siv hauv kev lag luam ua kua dej.

Tom ntej no koj yuav tsum txheeb xyuas cov kev sib txuas ntawm cov chaw nres nkoj ua ntej koj sim nruab ib lub hose lossis lub raj sib dhos, thiab cov chaw nres nkoj sib txuas yog cov uas tau teev saum toj no. Tom qab ntawd koj yuav tsum txheeb xyuas txoj kev sib khi tshwj xeeb, thiab qhov no feem ntau yuav yog lub kaum ntse ntse, cov xov sib txuas, lossis O-ring. Tom qab tau txiav txim siab txoj kev sib khi, koj yuav tsum siv lub rooj ntsuas ntsuas kom txiav txim siab lub rooj zaum.

Qhov kawg koj yuav tsum tau ua yog ntsuas cov xov, thiab qhov no yuav hu rau kev siv calipers. Los ntawm kev txiav txim siab tus naj npawb ntawm threads ib nti ntawm ob sab nraud txoj kab uas hla thiab sab hauv txoj kab uas hla, koj yuav tau txais ib tug meej nyeem ntawm xov loj. Tam sim no koj paub tseeb tias hom twg koj ua haujlwm nrog, nws yuav yooj yim heev rau koj hu rau tus neeg muag khoom thiab txiav txim qhov tseeb connector.
