DG4V-5: NG10 on-off valve uas feem ntau circuits twb tau laum rau
Lub valve ua nyob ib ncig ntawm plaub - av spool
Nqa ib lub DG4V-5 tawm ntawm nws lub thawv thiab thawj qhov koj pom yog qhov me me rau nws: lub cev cam khwb cia, ib lub pas uas swb hauv nws, thiab ib lossis ob lub solenoids bolted mus rau qhov kawg. Lub spool nqa plaub thaj av, thiab tus lej ntawd yog tag nrho cov ntsiab lus. Plaub thaj av cia cov roj ntsuas tau nce zuj zus thaum lub spool mus ncig, yog li lub valve tuaj yeem ua los teb maj mam es tsis txhob qhib snapping. Qhov twg lub tshuab muaj qhov hnyav hnyav dai ntawm lub actuator, qhov kev ua siab mos siab yog qhov ua kom lub siab tsis zoo ntawm cov kav dej.
Lub cev yog gasket mounted thiab siv plaub qhov kev sib txuas: siab ntawm P, ob qhov chaw nres nkoj A thiab B, thiab lub tank rov qab los ntawm T. Tus qauv 05 interface yog vim li cas lub valve tig mus rau ntau qhov chaw. Nws yog tib lub hneev taw uas kev lag luam tseem hu ua ANSI/B93.7M-D05, CETOP 5, NG10 thiab NFPA D05, yog li lub manifold twb tau laum rau ib qho ntawm cov npe yuav txais nws yam tsis tau kov.
Coils tuaj nyob rau hauv ob tsev neeg hluav taws xob, AC thiab DC, ob qho tib si ntawm cov ntub -armature hom. Vim tias lawv sib koom tib lub cev lub cev, kev hloov pauv ntawm cov khoom siv hluav taws xob tsis yuam kev hloov pauv ntawm manifold, uas tsim nyog paub thaum lub tshuab tau rov ua dua - qhia rau lub lag luam tshiab.
Nyeem tus lej ntawm daim ntawv teev npe
Code tsis yog ib txoj hlua random. Nws tau nyeem sab laug mus rau sab xis, thiab txhua lub blocks nqaim lub valve cia me ntsis ntxiv. Ua haujlwm los ntawm qhov piv txwv tiag tiag yog txoj hauv kev sai tshaj plaws kom pom nws:
Ob blocks ntes neeg tawm. Daim ntawv qhia caij nplooj ntoos hlav qhia koj tias yuav ua li cas thaum lub kauj yog de-energized: ibAtsim yog caij nplooj ntoos hlav offset rau ib kawg, aBtsim yog lub caij nplooj ntoos hlav center, aCtsim yog lub caij nplooj ntoos hlav nruab nrab nrog ib lub kauj ntawm txhua qhov kawg, thiab ib qhoNtsim tsis muaj caij nplooj ntoos hlav thiab tsuas nyob qhov twg nws tau muab tso. Tsab ntawvJnyob rau hauv lub thib tsib txoj hauj lwm yog ib tug spool tsim marker uas nyob ntawm seb spool koj xaj, tsis yog tus neeg siv khoom xaiv, yog li nws tsim nyog luam tawm raws nraim es tsis xav tias.

Kev ntseeg tau raug hais los ntawm MTTFd 150 xyoo rau ISO 13849. Tus lej tsim 20 txog 29 qhia qhov sib npaug ntawm qhov sib npaug, yog li tom qab tsim qauv poob rau hauv daim duab uas twb muaj lawm.
Qhov twg cov li qub no siv lawv lub neej ua haujlwm
Ib qho ntawm -off size 05 valve yog tus kws tshaj lij. Nws yog qhov koj ncav cuag thaum ib yam dab tsi yuav tsum mus rau ib txoj kev thiab tom qab ntawd lwm txoj kev, ntseeg tau, ob peb txhiab zaus hauv ib hnub. Ntawm lub tshuab txhaj tshuaj molding nws zaum hauv lub clamp thiab ejector circuits. Ntawm qhov chaw machining nws tuav clamping thiab pallet indexing. Ntawm chav tsev fais fab nws xaiv cov ceg ntawm lub voj voog nyob thiab muab cov seem rov qab rau hauv lub tank.
Txav mus rau sab nraud thiab tib lub valve tig rau ntawm cov twj tso kua mis tsheb thauj khoom kom ua raws cov boom thiab cov khoom tawm, ntawm excavators thiab loaders los xaiv ntawm cov khoom siv, thiab cov nroj tsuag mining rau conveyor, nres thiab slew tswj. Steel mills siv nyob rau hauv sawv ntsug thiab descaling circuits; hydraulic presses siv nws rau ram ua ntej, rov qab thiab tuav ntev hauv nruab nrab; tuag-casting machines siv nws rau kev txhaj tshuaj thiab ua raws li kev tswj hwm.
Test rigs yog qhov ntsiag to. Txhua qhov chaw ib ntu yuav tsum tau hloov mus rau hauv qhov kev txiav txim ruaj khov, thiab hloov tsis tau ua yeeb yam, qhov no yog lub valve uas xaus rau ntawm manifold.
Qhov koj tau txais rau cov nyiaj
Ib qho kev hloov koj tuaj yeem qhib.Txhua tus qauv DC tso cai rau kev hloov pauv hloov ceev. Haum ib lub orifice plug thiab lub spool mus qeeb dua, uas softens lub siab transient thiab calms lub tshuab uas yog banging.
Ib lub cev, tag nrho cov txheej txheem coils.Kaum ob lub cim hluav taws xob khiav ntawm 12 V DC mus txog 240 V AC, nyob rau hauv tsib lub coil vaj tse xws li DIN plugs nrog lub teeb qhia thiab Deutsch connectors nrog lub diode.
Ib daim ntawv teev npe ntev txaus kom haum rau lub voj voog.Kaum xya spool codes ntxiv rau sab laug- tes tsim, nyob rau hauv lub caij nplooj ntoos hlav offset, caij nplooj ntoos hlav centered thiab detent versions. Hauv kev xyaum koj pom cov haujlwm uas koj xav tau ntau dua li rov tsim dua ib puag ncig lub valve koj tuaj yeem tau txais.
Cov khoom siv uas muaj.Foob cov khoom siv 459057 rau AC thiab 459058 rau DC tsim, orifice plug kit 459065, thiab coils muaj nyob rau hauv ib tus zuj zus. Lub valve koj tuaj yeem kho tau muaj nqis ntau dua li qhov koj tuaj yeem hloov tau.
Tsawg pipework nyob ib ncig ntawm nws.Lub cev yog tsim los zaum nrog SystemStak qhaub cij li qub thiab cov txheej txheem subplates, uas yuav siv cov fittings thiab cov pob qij txha tawm ntawm lub manifold thiab shortens lub tsim.
Cov lus nug peb raug nug ua ntej kev txiav txim thawj zaug
Ntxiv L rau sab laug- txhais tes tsim ntawm ib qho ntawm cov no.
Xa daim ntawv cim npe, qhov ntau thiab qhov chaw. Yog tias lub luag haujlwm ntawm lub tshuab tseem ceeb, suav nrog kev ua haujlwm siab thiab qhov ntws, thiab peb yuav xyuas cov spool tiv thaiv nws ua ntej quoting.
