Ua ntej txhim kho lub pneumatic npauj npaim valve, cov kauj ruam hauv qab no yuav tsum tau ua kom tiav kom lub pneumatic npauj npaim valve ua haujlwm zoo dua.
1. Lub valve yuav tsum tau kuaj pom qhov muag ua ntej kev teeb tsa, thiab nws daim ntawv teev npe yuav tsum ua raws li lub teb chaws tus qauv tam sim no GB12220" General Valve Mark". Rau cov li qub uas nws lub siab ua haujlwm siab dua 1.0 MPa thiab txiav tawm cov yeeb nkab tseem ceeb, kev ntsuas lub zog thiab nruj yuav tsum tau ua ua ntej kev teeb tsa, thiab lawv tuaj yeem siv tsuas yog tom qab lawv tsim nyog.
2. Ua ntej kev teeb tsa, xyuas seb cov khoom ntawm lub pneumatic npauj npaim valve puas ploj lawm thiab cov qauv yog qhov tseeb, xyuas kom tsis muaj cov khib nyiab hauv lub valve lub cev, thiab tsis muaj qhov thaiv ntawm lub solenoid valve thiab muffler.
3. Tag nrho cov li qub thiab lub tog raj kheej yog sib xyaw ua ke.
4. Thaum lub sij hawm kuaj lub zog, qhov kev ntsuam xyuas siab yuav tsum yog 1.5 npaug ntawm nominal siab thiab lub sij hawm yuav tsum tsis pub tsawg tshaj 5min. Lub plhaub valve thiab ntim khoom yuav tsum ua tau raws li qhov yuav tsum tau ua.
5. Ntaus lub tog raj kheej tiv thaiv lub valve (qhov kev taw qhia ntawm kev teeb tsa yog qhov sib npaug lossis perpendicular mus rau lub valve lub cev), thiab tom qab ntawd xyuas seb cov ntsia hlau qhov zoo li cas thiab tsis muaj qhov sib txawv ntau dhau. Yog tias muaj qhov sib txawv me ntsis, tig lub tog raj kheej me ntsis ntxiv, thiab tom qab ntawd muab cov ntsia hlau nruj.
6. Tom qab kev teeb tsa tiav lawm, debug lub pneumatic npauj npaim valve (cua pa siab yog 0.4 ~ 0.6MPa nyob rau hauv ib txwm muaj), thiab lub solenoid valve yuav tsum tau manually qhib thiab kaw thaum lub sij hawm debugging lag luam (kev tuav tswj yuav ua tau zoo tom qab lub solenoid valve coil yog de-energized).
7. Defa yuav tsum tau khaws cia qhuav ua ntej kev teeb tsa, thiab yuav tsum tsis txhob muab cia rau hauv qhov qhib cua.
8. Ua ntej txhim kho lub npauj npaim valve, xyuas cov raj xa dej rau tej yam txawv teb chaws xws li vuam slag.
9. Kev ceev qhib thiab kaw quab yuam ntawm npauj npaim valve lub cev yog qhov nruab nrab, thiab lub zog ntawm lub npauj npaim valve sib tw rau lub zog ntawm tus actuator xaiv.
10. Lub flange specification rau npauj npaim valve kev twb kev txuas yog lawm, thiab cov yeeb nkab clamp flange yog raws li tus npauj npaim valve flange txheem. Nws raug nquahu kom siv cov flanges tshwj xeeb rau cov npauj npaim li qub, tsis yog vuam flanges.
11. Paub meej tias flange vuam yog qhov tseeb. Tom qab lub npauj npaim valve yog ntsia, lub flange yuav tsum tsis txhob welded kom tsis txhob scalding cov roj hmab qhov chaw.
12. Cov ntsia hlau flange yuav tsum yog nruab nrab thiab nruab nrab nrog lub qhov ntxig npauj npaim valve.
13. Nruab tag nrho cov flange bolts thiab ceev lawv los ntawm txhais tes kom paub meej tias tus npauj npaim valve thiab flange tau ua raws, thiab tom qab ntawd ua tib zoo qhib lub npauj npaim valve kom qhib tau yooj yim.
Lub valve yuav tsum qhib tag nrho. Siv ib tug ciaj ntswj kom nruj cov bolts nyob rau hauv ib tug kab pheeb ces kaum. Tsis xav tau lub tshuab ntxhua khaub ncaws, thiab cov bolts yuav tsum tsis txhob nruj nruj heev kom tsis txhob muaj kev puas tsuaj loj ntawm lub nplhaib valve thiab qhib thiab kaw lub zog ntau dhau.
Thaum lub sij hawm installation, lub disc yuav tsum nres nyob rau hauv lub kaw txoj hauj lwm. Txoj haujlwm qhib yog txiav txim siab los ntawm lub kaum sab xis ntawm lub phaj npauj npaim. Rau npauj npaim li qub nrog bypass li qub, lub bypass valve yuav tsum tau qhib ua ntej qhib. Kev teeb tsa ntawm pneumatic npauj npaim valve yuav tsum tau ua raws li cov chaw tsim khoom' cov lus qhia. Lub npauj npaim hnyav valve yuav tsum tau ntsia kom ruaj khov.
