Nyob rau hauv lub teb ntawm thermal zog tiam, kev lag luam tsav tsheb thiab nkev siv thiab roj turbine yog cov lag luam muaj zog thiab muaj zog yog cuam tshuam nrog kev ua haujlwm thiab cov cuab yeej siv lub neej. Overspeed kev tiv thaiv tswj (OPC) yog "kab kawg ntawm kev tiv thaiv" kom paub tseeb ntawm cov kev nyab xeeb ntawm cov pa turbine. Raws li tus tub ntxhais Actuator ntawm OPC system, tusOPC Solenoid Valve165.31.56g03 tau dhau los ua ib feem tsis tseem ceeb ntawm cov chav kev nyab xeeb niaj hnub tswj nrog nws cov lus teb nrawm thiab kev ntseeg siab.

OPC Solenoid Valve 165.31.31.56g03 yog qhov tshwj xeeb tsim rau kev tiv thaiv kev tiv thaiv. Nws cov tub ntxhais lub zog muaj xws li:

1. Ceev txiav lub zog hluav taws xob: los ntawm kaw lub tsev loj chav valve lossis kev tswj hwm lub valve, cov kua dej ua haujlwm yog thaiv ntawm kev nkag mus rau lub tshuab luam yeeb;

2. Kev ywj pheej redundant

3. Cov lus teb kom raug: sib koom tes nrog lub nrawm nrawm thiab PLC / DCS system kom ua tiav qhov pib ua haujlwm thiab kev txiav txim synchronization.

OPC solenoid valve 165.31.31.56g03 cov qauv tsim qauv, thiab cov khoom siv tseem ceeb suav nrog:

- Lub cev siv hluav taws xob thiab cov khoom siv valve: cov khoom siv feem ntau 316 steel steel lossis alloy steel, tiv taus 20mpa) thiab kub siab (nruab nrab ultrasonic ℃);

- Electromagnetic tsav chav: Siab sib nqus permeability chev nrog cov qis sib txhuam valve cov sijhawm ≤50ms;

- Caij nplooj ntoos hlav rov ua mechanism: Tsis siv neeg pib dua tom qab lub zog tsis muaj kev zam txim kom tsis txhob rov ua kom rov zoo dua qub;

- Kev sib sau ua ke: Polytetrafluoroethylene (PTFE) lossis cov qauv siv hlau nyuaj, kev coj mus rau cov roj ua haujlwm tsis kam thiab lub neej ntev.

OPC Solenoid Valve 165.31.31.56g03 feem ntau yog hloov "Tsim (thov saib cov qauv lus piav qhia rau cov ntsiab lus), thiab nws cov txheej txheem ua haujlwm yog raws li nram no:

1. Kev ua haujlwm zoo li qub: lub solenoid valve yog nyob rau hauv lub xeev kaw, thiab cov kab ke hydraulic tswj kev qhib lub valve;

2. Overspeed Bigger: Thaum tus ceev sensor kuaj pom cov cim liab, tswj hwm xa daim 24vdC (lossis 110VDC) mem tes rau Solenoid Valve;

3. Valve action: The solenoid coil is energized to generate magnetic force, overcome the spring force to pull the valve core, quickly release the control oil pressure, and force the main steam valve to close;

4. Kev pib dua tshiab: Tom qab qhov txhaum yog tshem tawm, lub zog solenoid valve yog qhov chaw nres tsheb valve kom rov tsim dua, thiab lub turbine rov qab mus rau lub xeev uas tswj tau.

Raug Daim Ntawv Teev Lus

1. Thermal fais fab tsim tawm cov khoom: hauv cov khoom loj ntawm 600MW thiab saum toj no lub tog raj kheej (IP

2. Cov roj av ua ke ua ke ua ke ua ke: Roj av muaj kev pheej hmoo ntawm cov roj cutchet valve kom ntseeg tau tias cov roj tseb mus rau qhov muaj kev nyab xeeb nyob hauv 0.5 vib nas this.

3. Muaj cov tsav chav turbine: rov qab lub zog turbines siv nyob rau hauv petrochemical, papermakical thiab lwm thaj teb kom tiv thaiv kev sib txawv ntawm cov txheej txheem txawv txav.

Raws li "qhov kawg tus saib xyuas" ntawm lub ncu ntawm cov saw kev nyab xeeb, kev ua haujlwm ntawm lubOPC Solenoid Valve165.31.56g03 txiav txim siab ncaj qha seb cov tsev puas tuaj yeem khiav nyab xeeb hauv lub sijhawm tseem ceeb. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm cov ntaub ntawv kev tshawb fawb thiab kev tswj hwm kev yoog raws kev tiv thaiv kev nyab xeeb rau lub zog thiab kev lag luam. Hauv cov ntawv thov tiag tiag, cov neeg siv yuav tsum nruj ua raws li cov khw muag khoom tshwj xeeb thiab cov tswv yim scientificies raws li cov haujlwm ua haujlwm kom ua rau lawv cov kev tiv thaiv kev tiv thaiv.

Los ntawm txoj kev, peb tau muab cov khoom seem rau cov nroj tsuag fais fab thoob ntiaj teb tau 20 xyoo, thiab peb muaj kev paub nplua nuj thiab cia siab tias yog kev pabcuam rau koj. Nrhiav rau pem hauv ntej kom hnov ​​lus los ntawm koj. Kuv cov ntaub ntawv tiv toj yog raws li hauv qab no:
