Cov pob hluav taws xob hluav taws xob yog siv ntau yam kev lag luam, feem ntau yog siv los txiav tawm lossis txuas qhov nruab nrab hauv cov kav dej, thiab tseem tuaj yeem siv rau kev hloov kho thiab tswj cov kua dej. Nws yog lub raj xa dej siab tiv thaiv rau kev lag luam automation txheej txheem tswj. Vim qhov tshwj xeeb ntawm lub tshuab hluav taws xob, hluav taws xob actuator feem ntau yuav ua rau lub cev muaj zog lossis lwm qhov chaw vim yog ib puag ncig thiab cov laj thawj sab hauv ntawm lub valve pipeline thaum siv, uas yuav cuam tshuam rau lub neej kev pab cuam ntawm hluav taws xob valve.
Yog li ntawd, kev saib xyuas kom zoo tuaj yeem txuas ntxiv lub neej kev pabcuam ntawm lub pob hluav taws xob, thiab tib lub sijhawm txhim kho kev ua haujlwm, txo qis sijhawm, thiab txuag cov nqi hloov.
Electric pob valve tu thiab tu
1. Lub pob hluav taws xob yuav tsum tau muab cia rau hauv chav qhuav thiab qhov cua, thiab ob qhov kawg ntawm txoj kev yuav tsum tau thaiv.
2. Lub pob hluav taws xob uas khaws cia rau lub sijhawm ntev yuav tsum tau kuaj xyuas tsis tu ncua kom tshem tawm cov av thiab siv cov roj los tiv thaiv xeb rau ntawm qhov chaw ua haujlwm.
3. Tom qab kev teeb tsa, cov khoom siv yuav tsum tau kuaj xyuas tsis tu ncua.
4. Rau lub pob hluav taws xob hauv kev ua haujlwm, ntau yam valve yuav tsum ua kom tiav thiab tsis zoo.
5. Lub bolts ntawm lub flange thiab lub bracket yuav tsum tsis txhob muaj ob peb, cov xov yuav tsum tsis tu ncua, thiab tsis pub looseness.
6. Cov txiv ntseej nruj ntawm lub tes tuav yuav tsum tau nruj rau lub sijhawm yog tias pom tias xoob, kom tsis txhob hnav cov kev sib txuas lossis plam lub tes tuav thiab daim ntawv teev npe.
7. Yog hais tias lub handwheel ploj lawm, nws tsis raug tso cai los hloov nws nrog ib tug adjustable ciaj ntswj, thiab nws yuav tsum tau nruab rau lub sij hawm.
8. Lub caj pas ntim khoom tsis raug tso cai rau skewed los yog tsis muaj pre-tightening clearance.
9. Rau cov hluav taws xob li qub nyob rau hauv ib puag ncig uas yooj yim los ntawm nag, daus, plua plav, xuab zeb thiab lwm yam av, lub qia valve yuav tsum tau nruab nrog lub hau tiv thaiv.
10. Lub nplai ntawm lub pob hluav taws xob yuav tsum ua kom tiav, raug thiab meej.
11. Cov ntsaws ruaj ruaj, lub kaus mom, thiab cov khoom siv pneumatic ntawm lub pob hluav taws xob yuav tsum ua kom tiav thiab tsis zoo. Yuav tsum tsis muaj dents lossis tawg hauv lub tsho tiv thaiv.
Tsis tas li ntawd, hluav taws xob pob valve actuators muaj cov cai tshwj xeeb, uas yog, lawv yuav tsum muaj peev xwm txwv lub zog torque (axial force) thiab lub kaum sab xis ntawm kev sib hloov. Thaum cov kev qhia tshwj xeeb ntawm cov cuab yeej hluav taws xob tau txiav txim siab, nws qhov kev tswj torque kuj tau txiav txim siab. Feem ntau, nws khiav nyob rau hauv lub sij hawm predetermined thiab lub cev muaj zog yuav tsis overloaded. Txawm li cas los xij, overload yuav tshwm sim yog tias cov xwm txheej hauv qab no tshwm sim: Ua ntej, lub zog hluav taws xob qis qis, thiab qhov xav tau torque tsis tuaj yeem tau, kom lub cev muaj zog nres; thib ob, lub torque txwv mechanism yog teem incorrectly ua kom nws loj dua lub nres torque. Ua rau lub cim tsis tu ncua ntawm lub zog ntau dhau, ua rau lub cev tsis muaj zog; thib peb, kev siv tsis sib xws, cov khoom siv hluav taws xob tsim hluav taws xob ntau tshaj qhov tso cai rau qhov ntsuas kub ntawm lub cev muaj zog; Thib plaub, vim qee qhov laj thawj, lub zog torque txwv lub zog tsis ua haujlwm, ua rau lub zog torque ntau dhau Fifth, kev siv ib puag ncig kub siab dhau, uas kuj txo cov thermal muaj peev xwm ntawm lub cev muaj zog.
1. Lub ambient kub yuav tsum tswj tsis pub dhau -25 degree -70 degree .
2. Cov khoom tawg-pov thawj hluav taws xob pob li qub yuav tsum raug xaiv rau ntau lub sijhawm, xws li tsis ruaj tsis khov tam sim no, ib puag ncig corrosion, nplaim taws thiab tawg, tshwj xeeb tshaj tawm, lub sijhawm ntev tsis tu, thiab lwm yam.
3. Txij li thaum lub tshuab hluav taws xob yog qhov nyuaj, nws yuav tsum tsis txhob muab tshem tawm ntawm nws tus kheej thaum nws tsis tuaj yeem tiv thaiv kev raug mob.
4. Raws li ib txwm muaj, nws tsis raug tso cai rau khob lub pob hluav taws xob los yog muab cov khoom tso ua ke.
