Tus ntse valve positioner yog digital tswj-loop accessory uas mounts ntawm pneumatic tswj valve thiab converts 4-20 mA tam sim no teeb liab mus rau ib tug meej proportional cua tso zis rau tus actuator. Ua ib ncig ntawm ib qho kev sib xyaw microprocessor thiab lub LCD module hauv zos, nws khiav ib qho -kov tsis siv neeg stroke calibration, yog li kev ua haujlwm hauv teb tsis nyob ntawm phau ntawv flapper -nozzle tuning. Nws lees txais 4-20 mA analog input thiab txhawb HART thiab RS485 Modbus kev sib txuas lus, cia lub valve mus ncig, muab cov ntaub ntawv siab thiab lub tswb raug nyeem rov qab rau hauv cov nroj tsuag DCS. Onboard tus kheej-kev kuaj mob tsis tu ncua kuaj lub valve, huab cua- muab cov xau thiab teeb liab teeb meem thiab tsa lub tswb ua ntej kev mus ncig yuav tshwm sim. Nws cov kev vibration- thiab plua plav- tiv taus pneumatic module, IP67 enclosure thiab xaiv Ex d IIB T4 tawg-pov thawj kev tsim kho yog tsom rau cov txheej txheem hnyav uas cov qauv analog positioners zoo li drift.
Vim hais tias tus ntse positioner sib koom ua ke firmware, pneumatics thiab sensing rau hauv ib lub cuab yeej, nws qhov tseeb nyob ntawm kev sib dhos ua haujlwm tsawg dua li ntawm cov khoom siv hluav taws xob. Peb pab neeg tswj R&D txhim kho lub positioner's digital board thiab teeb liab logic nyob rau hauv -tsev es tsis yog reselling generic modules, uas cia peb qhib lub auto-calibration thiab diagnostics cwj pwm rau diaphragm, lub tog raj kheej thiab scotch-yoke actuators ib yam nkaus. Rau cov chaw nyob hauv huab cua txias lossis chaw muaj kev phom sij, tib lub hauv paus engineering no txhawb kev tawg raws li kev ua kom tawg - pov thawj thiab qis - qhov kub thiab txias, yog li tus neeg yuav khoom tsis tas yuav muab cov ntawv pov thawj hluav taws xob cais tawm ntawm lub valve.

Daim ntawv thov
1. Petrochemical siab - kub thiab siab - siab tswj li qub
Cov lus tawm tswv yim digital thiab tus kheej -kev kuaj mob ua kom muaj kev mus los yog qhov chaw ntim cov kev sib txhuam thiab qhov sib txawv ntawm qhov sib txawv yuav ua rau qhov sib txawv ntawm qhov chaw nres nkoj, txo qhov kev mus ncig uas tsis tau npaj tseg ntawm qhov kev txiav txim siab tseem ceeb.
2. Coal - tshuaj slurry thiab FGD desulfurization li qub
IP67 plua plav- kaw vaj tse thiab kev co- tiv thaiv pneumatics tuav calibration hauv plua plav, vibrating slurry kev pab cuam, thiab HART diagnostics chij hnav ua ntej lub valve sticks.
3. Lub zog loj- cog cov kab ntse ntse thiab lithium- cov roj teeb siv hluav taws xob
Modbus/HART readback pub lub valve kev noj qab haus huv rau hauv DCS, ua kom muaj kev saib xyuas kev kwv yees ntawm cov Islands tuaj nyob deb nroog uas taug kev los ntawm phau ntawv - downs yog kim heev.
Kev kho kom haum
- Explosion-cov pov thawj variant (Ex d IIB T4) rau thaj chaw muaj kev phom sij
- Tsawg-kub thiab corrosion- tiv taus variants rau txias- qhov chaw lossis kev pabcuam corrosive
- Kev xaiv kev sib txuas lus: 4-20 mA analog, HART lossis RS485 Modbus
- Mounting brackets rau diaphragm, lub tog raj kheej thiab scotch -yoke actuators
- OEM / ODM branding thiab firmware configuration ib qhov project
- Kev sim ua qauv raws li tus neeg siv khoom actuator thiab kev ua haujlwm
Ntim & Kev thauj mus los
Txheem export ntim rau lub positioner thiab nws cov khoom mounting. Ua ntej ua zaub mov xa tuaj peb muab cov teeb liab -calibration test video, packing duab, packing list thiab cov ntaub ntawv kev lis kev cai xav tau rau export xaj. Lub cargo yog taug qab los ntawm logistics; yog hais tias ib feem tuaj txog puas peb xa ib tug tej thaj chaw deb video kho phau ntawv qhia los yog lub nkoj hloov qhov chaw tam sim ntawd.
FAQ
Q. Koj puas tuaj yeem muab cov qauv kuaj ntawm tus ntse positioner ntawm peb lub valve?
A. Yog. Peb tsuas yog them tus nqi khoom siv rau cov qauv thiab tsis ntxiv tus qauv siab - tus nqi pabcuam; cov qauv raug kuaj tawm tsam koj tus actuator thiab tswj cov teeb liab ua ntej xa.
Q. Koj puas muaj kev tawg- pov thawj thiab qis - kub versions?
A. Yog. Chav tsev txheem muaj kev tiv thaiv IP67; Ex d IIB T4 explosion-cov ntaub ntawv pov thawj thiab qis-kub / corrosion-resistant variants tuaj yeem hloov kho rau kev phom sij lossis txias- site applications.
Q. Koj tuaj yeem lav qhov zoo thiab kev txhawb nqa tom qab xa khoom li cas?
A. Peb khiav ISO9001 zoo system thiab txhua tus positioner mus dhau lub teeb liab -linearity thiab huab cua-tightness kuaj ua ntej xa zaub mov. Kev mob siab rau tom qab- pab pawg muag khoom nrog lub valve thiab cov cuab yeej ntsuas keeb kwm yav dhau los taug qab cov khoom thauj thiab muab kev txhawb nqa chaw taws teeb lossis chaw hloov pauv sai.
