Ntawm WUXI XINMING AUTO-CONTROL VALVES INDUSTRY CO., LTD., peb pab neeg ua haujlwm engineering tshuaj xyuas ntau qhov kev thov ntsuas qhov ntsuas txhua lub lis piam. Qhov yuam kev tshaj plaws uas peb pom hauv kev lag luam? Sizing lub pneumatic khib thiab pinion actuator raws li lub valve "khiav torque" los yog tsuas yog kwv yees raws li cov yeeb nkab txoj kab uas hla.
Peb tau pom undersized actuators tsis ua kom tag nrho lub pob valve thaum muaj xwm txheej ceev, thiab peb tau pom cov neeg loj dua cov lus khoov valve stems los ntawm kev cuam tshuam ntau heev. Sizing tsis yog hais txog kev xaiv tus qauv los ntawm phau ntawv teev npe; nws yog hais txog kev nkag siab qhov tiag -lub ntiaj teb physics ntawm koj cov kav dej. Ntawm no yog peb daim teb - sim mus kom ze kom tau nws txoj cai.
1. Hunt rau Breakaway Torque, Tsis yog khiav torque xwb
Thaum lub pob lossis npauj npaim valve tau zaum hauv ib txoj haujlwm rau lub lis piam lossis hli, cov khoom siv lub rooj zaum me ntsis deforms nyob ib ncig ntawm lub disc lossis pob. Lub zog yuav tsum tau muab tshem tawm - lub zog tawg tawm - feem ntau yog 30% mus rau 50% siab tshaj qhov xav tau kom nws txav mus (khiav torque).
Tiag - ntiaj teb scene: Xyoo tas los, ib tus neeg siv khoom hauv kev lag luam cov ntaub ntawv thiab cov ntawv loj tau ua rau lawv cov actuators rau 8-inch npauj npaim li qub raws li cov ntaub ntawv dej huv. Tab sis lawv qhov nruab nrab tiag tiag yog cov kua nplaum nplaum. Cov li qub tau jammed ib nrab ntawm cov hlab ntsha tawg thaum ua haujlwm. Peb rov xam siv lub breakaway torque rau high-viscosity kua thiab upgraded tus actuator loj. Nco ntsoov nug koj lub chaw tsim khoom valve rau qhov siab tshaj plaws breakaway torque nyob rau hauv koj cov kev ua haujlwm tshwj xeeb.
2. Siv txoj cai "Golden Rule" ntawm Safety Margins
Ntawm Xinming, peb yeej tsis pom zoo kom nruj 1: 1 match ntawm actuator tso zis thiab valve torque. Peb siv tus qauv 20% txog 30% kev nyab xeeb. Vim li cas? Vim tias qhov hloov pauv siab ntawm cov kav dej, cov khib nyiab me me hauv kab, lossis me ntsis poob rau hauv cov nroj tsuag huab cua siab tuaj yeem noj koj cov paj tam sim ntawd. Yog tias koj lub valve xav tau 100 Nm kom tawg, koj xav tau lub tshuab hluav taws xob uas xa tawm yam tsawg kawg 120 Nm txog 130 Nm ntawm koj qhov tsawg kawg nkaus muaj cua siab.
3. Txheeb xyuas qhov tseeb cog cua siab
Qhov no yog qhov uas ntau qhov project dawm. Tus actuator nameplate tej zaum yuav raug ntsuas rau 6 bar (87 psi), tab sis los ntawm lub sij hawm compressed cua mus los ntawm ntau pua meters ntawm piping, lim, thiab regulators, lub siab ntawm lub valve inlet tej zaum yuav tsuas yog 4.5 bar. Txij li thaum lub khib thiab pinion actuator lub torque tso zis poob linearly nrog huab cua siab, sizing raws li 6 bar thaum koj tsuas muaj 4.5 bar yuav ua rau ib tug stalled valve. Ib txwm me me raws li qhov qis tshaj plaws tau lees paub huab cua siab ntawm qhov chaw.
4. Tus account rau qhov nruab nrab thiab kub
Lub pob valve tuav cov huab cua huv si coj txawv txawv ntawm ib qho kev tuav abrasive mining slurry lossis siab -kub. Qhov kub thiab txias tuaj yeem ua rau tus qauv PTFE lub rooj zaum, ua kom muaj kev sib txhuam, thaum cov xov xwm abrasive tuaj yeem tau qhab nia ntawm lub pob, spiking qhov xav tau torque. Rau kev cog qoob loo tsis ntev los no nyob rau hauv Middle East, qhov kub ntawm qhov nruab nrab mus txog 50 degree, thiab cov kav dej yog nyob ntawm 120 degree. Peb yuav tsum tau ua kom muaj qhov thermal expansion ntawm lub valve sab hauv, uas ua rau lub rooj zaum torque loj dua piv rau cov qauv chav- kub catalogs.
5. Muab ob npaug rau-Ua yeeb yam vs. Caij nplooj ntoos hlav rov qab qhov loj me
Yog tias koj siv lub caij nplooj ntoos hlav rov qab (tsis ua tiav- nyab xeeb) actuator, nco ntsoov tias cov springs noj ib feem tseem ceeb ntawm tus actuator lub ntim thiab quab yuam. Lub "caij nplooj ntoos hlav stroke" torque (feem ntau yog kaw stroke) yuav qis dua "air stroke" torque. Koj yuav tsum xyuas kom meej tias qhov tsawg kawg nkaus torque tso tawm ntawm lub caij nplooj ntoos hlav rov qab actuator- ntawm qhov kawg ntawm lub caij nplooj ntoos hlav stroke, qhov twg cov springs tau tag nrho compressed- tseem tshaj koj li valve lub breakaway torque ntxiv rau qhov kev nyab xeeb margin.
Tau txais koj qhov loj me yog thawj zaug
Sizing lub pneumatic khib thiab pinion actuator rau pob thiab npauj npaim li qub yog qhov sib npaug ntawm kev nyab xeeb, nqi, thiab kev txwv kev siv tshuab. Ntawm WUXI XINMING AUTO-CONTROL VALVES INDUSTRY CO., LTD., peb tsis yog muag actuators xwb; peb engineer txhim khu kev qha valve automation.
Tsis txhob muaj kev pheej hmoo ntawm cov kav dej xau, hluav taws xob hluav taws xob hluav taws xob, lossis khoov lub valve stems ntawm kev kwv yees. Xa peb koj li daim ntawv teev cov ntaub ntawv torque, nruab nrab cov ntsiab lus, thiab qhov chaw huab cua siab. Peb pab neeg yuav muab ib tug dawb, meej actuator sizing xam thiab ib tug customized kev pom zoo kom paub tseeb tias koj lub cev ua hauj lwm flawlessly rau xyoo. Hu rau Xinming hnub no los tham txog koj qhov project automation valve tom ntej.
