Cov li qub ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw lag luam. Thaum siv lub li qub, qee zaum yuav muaj teeb meem xau, uas yuav tsis tsuas yog ua rau lub zog thiab cov peev txheej pov tseg, tab sis kuj tseem yuav ua rau tib neeg kev noj qab haus huv thiab ib puag ncig puas tsuaj. Yog li ntawd, kev nkag siab txog qhov ua rau muaj qhov xau thiab cov kev daws teeb meem yog qhov tseem ceeb rau kev tswj hwm kev ua haujlwm ib txwm ntawm cov khoom siv thiab tiv thaiv ib puag ncig.

1. Cov khoom kaw poob tawm ua rau xau

(1) Lub zog ua haujlwm ua rau qhov kaw qhov chaw tshaj qhov chaw tau teem tseg, thiab qhov txuas nrog puas lawm thiab tawg;

(2) Cov khoom siv ntawm lub connector xaiv tsis haum, thiab nws yog corroded los ntawm cov khoom nruab nrab thiab hnav los ntawm cov tshuab rau ib lub sijhawm ntev.

Txoj kev txij nkawm:

(1) Kaw lub valve nrog lub zog tsim nyog, qhib lub valve tsis pub dhau qhov chaw tuag sab saud, tom qab lub valve qhib tag, lub log tes yuav tsum rov qab me ntsis;

(2) Xaiv cov khoom siv tsim nyog, cov fasteners siv rau kev sib txuas ntawm qhov kaw thiab lub valve qia yuav tsum muaj peev xwm tiv taus qhov corrosion ntawm qhov nruab nrab, thiab muaj qee yam lub zog kho tshuab thiab hnav tsis kam.

2. Xaus ntawm qhov chaw ntim khoom (muaj feem ntau)

(1) Kev xaiv cov khoom sau tsis raug, tsis tiv taus qhov xeb ntawm cov khoom nruab nrab, tsis ua tau raws li qhov siab lossis lub tshuab nqus tsev, kub lossis kub qis ntawm lub valve;

(2) Cov khoom ntim tsis tau teeb tsa kom raug, thiab muaj qhov tsis zoo xws li tiam me me, qhov sib koom ua ke tsis zoo, nruj thiab xoob;

(3) Cov khoom siv filler dhau lub sijhawm siv, tau laus zuj zus, poob ntawm elasticity;

(4) Qhov tseeb ntawm lub valve tsis siab, khoov, xeb, hnav thiab lwm yam tsis zoo;

(5) Tus naj npawb ntawm cov nplhaib ntim khoom tsis txaus, thiab lub qog tsis raug nias kom nruj;

(6) Lub qog, ntsia hlau, thiab lwm qhov chaw puas lawm, yog li ntawd lub qog tsis tuaj yeem raug nias;

(7) Kev ua haujlwm tsis raug, siv zog ntau dhau, thiab lwm yam;

(8) Lub qog yog skewed, qhov sib txawv ntawm lub qog thiab lub valve qia yog me dhau los yog loj dhau, ua rau lub valve qia hnav thiab packing puas tsuaj.

Txoj kev txij nkawm:

(1) Cov khoom siv thiab hom khoom siv yuav tsum tau xaiv raws li cov xwm txheej ua haujlwm;

(2) Nruab cov khoom ntim kom raug raws li cov cai tswjfwm, cov khoom ntim yuav tsum muab tso rau thiab nias txhua lub voj voog, thiab qhov sib koom ua ke yuav tsum yog 30C lossis 45C;

(3) Lub sijhawm siv ntev dhau lawm, laus zuj zus, cov khoom puas yuav tsum tau hloov pauv raws sijhawm;

(4) Lub qia valve yuav tsum tau ncaj thiab kho tom qab khoov thiab hnav, thiab cov uas puas lawm yuav tsum tau hloov pauv raws sijhawm;

(5) Cov khoom ntim yuav tsum tau teeb tsa raws li tus lej ntawm cov nplhaib teev tseg, lub qog yuav tsum tau nruj thiab sib npaug, thiab lub tes tsho nias yuav tsum muaj qhov sib txawv ua ntej nruj dua ntau dua 5 hli;

(6) Cov hau, cov ntsia hlau thiab lwm yam khoom uas puas lawm yuav tsum tau kho lossis hloov pauv raws sijhawm;

(7) Yuav tsum ua raws li cov txheej txheem ua haujlwm, tshwj tsis yog qhov cuam tshuam ntawm lub log tes, kom ua haujlwm sai dua;

(8) Lub gland bolt yuav tsum tau nruj kom sib npaug thiab sib npaug. Yog tias qhov sib txawv ntawm gland thiab lub valve stem me dhau, qhov sib txawv yuav tsum tau nce ntxiv kom haum; Gland thiab stem clearance loj dhau, yuav tsum tau hloov.
