Vim li cas thiaj ua GATE rooj VIBS xaiv ib txwm muaj pitfalls? Cov 5 'invisible cuab' ob tus nqi ntawm kev tsim khoom!

Hauv kev siv hluav taws xob tshuab hluav taws xob,Rooj vag Li Qubyog qhov tseem ceeb txiav cov khoom siv. Kev xaiv tsis raug cai tuaj yeem ua rau muaj kev txwv tsis tu ncua thiab kev ua haujlwm qeeb dua, thiab muaj mob hnyav, kev nyab xeeb rau tag nrho cov haujlwm. Txawm li cas los xij, nyob rau hauv kev muaj tiag, tshaj 60% ntawm GATE Valve tsis ua qia los ntawm "qhov yuam kev tsawg" thaum lub sijhawm xaiv. Vim li cas thiaj ua rooj vag li qub nrog tib cov nominal tsis muaj qhov sib txawv? Daim ntawv no nthuav tawm 5 kev xaiv xaiv xaiv los pab koj kom tsis txhob pitfalls.


Cuab 1: Lub nominal siab (PN) yog falsely daim ntawv lo, thiab tsis txaus siab siab tsis txaus yuav ua rau muaj kev puas tsuaj loj

Lub ntsej muag nrov yog cov ntsiab lus tsis sib xws ntawm rooj vag li qub, tab sis qee cov tuam txhab feem ntau txiav cov fab ntawm cov ntaub ntawv txhawm rau txo cov nqi. Piv txwv li, rau lub rooj vag valve nrog ib tus nominal pn16, yog tias cov khoom siv hluav taws xob phom sij yuav poob qis ntawm 16MPA rau 6MPA. Ib qho kev ua haujlwm qee yam kev lag luam kev lag luam ib zaug txiav txim siab hom rooj vag valve, thiab tom qab 3 lub cev ua haujlwm tau tawg, ua rau muaj kev ploj ncaj qha rau 800000 yuan. Xaiv tus nqi xaiv: Cov chaw tsim khoom yuav tsum tau muab cov ntaub ntawv kuaj ntsuas thiab paub tseeb ntawm PN tus nqi thiab cov ntaub ntawv ntawm lub cev valve, npog valve, thiab valve qia.


Cuab 2: Mismatched sealing cov khoom siv nto, to ua cov cai

Kev sib khi kev ua tau zoo ntawm rooj vag li qub yog nyob ntawm qhov sib xyaw ntawm cov khoom sib khi ntawm cov khoom sib luag thiab cov haujlwm ua haujlwm feem ntau saib xyuas. Piv txwv li, kev sib tw sib zog sib npaug (WCB + Stl Stellite Alloy) yog qhov tsim nyog rau kub, thaum cov roj hmab muag muag rooj vag (roj hmab Ib qho dej phwj dej ib zaug siv cov rooj zaum muag muag muag rau cov kav dej lim dej uas muaj cov av nplaum. Tsis pub dhau ib hlis xwb, kev sib khi saum npoo tau hnav thiab xau, yuam kev hloov nrog cov teeb meem rooj vag nyuaj los daws cov teeb meem. Xaiv cov yuam sij: kom meej meej txhais cov muaj pes tsawg leeg, thiab siab ntawm qhov nruab nrab, thiab siab xaiv cov chaw sib tw ntau dua li cov kev ua haujlwm txwv tus nqi.


Cuab 3: Rov qab xaiv ntawm Valve Bem qauv qauv, teeb meem ntawm kev ua haujlwm thiab txij nkawm

Lub qia qauv ntawmRooj vag Li Qubtau muab faib ua qhib qia thiab zais qia, thiab xaiv yuav tsum yog raws li cov chaw teeb tsa thiab cov chaw saib xyuas txhua zaus. Pig Vag Rooj vag yog muaj ntau rau cov plua plav thiab corrosion vim yog qhov chaw ntawm lub valve qia tuaj yeem pom ncaj qha thaum txij nkawm; Lub ntsej muag zais Valve muaj cov qauv kev cog lus thiab yog qhov tsim nyog rau chaw txwv tsis pub, tab sis ib zaug tag nrho lub valve xav tau disassembled. Vim tias tsis muaj kev txiav txim siab rau kev kho kom yooj yim, ib qho chaw sib tw subway Xaiv tus tseem ceeb: muaj kev saib xyuas txaus thiab nquag saib xyuas yog yuav tsum tau xaiv cov ncej pom tau; Qhov chaw muaj tsawg tsawg thiab kev ua haujlwm ntev yuav tsum tau siv ntawm cov lej zais.

Cuab 4: kev tsav tsheb tsav tsheb, tsis txaus ntseeg ntawm kev ua tau zoo thiab raug nqi

Kev tuav rooj vag cov li qub muaj cov nqi qis, tab sis cov automation zoo ntawm cov rooj vag rooj vag yog feem ntau underestimated. Piv txwv li, hauv kev tiv thaiv hluav taws kub uas xav tau chaw taws teeb tswj, kev tuav rooj sib tw puas yuav tsum tau ua haujlwm rau ntawm lub chaw haujlwm thiab muaj cov sijhawm teb qeeb; Lub rooj vag fais fab valve tuaj yeem txuas nrog hluav taws sib txuas system thiab tuaj yeem qhib thiab kaw tsis pub dhau 3 vib nas this. Ib qho kev lag luam ua lag luam ib zaug siv cov kev tuav rooj sib tw rau cov nqi, tab sis thaum lub sijhawm hluav taws, cov neeg ua haujlwm tsis tuaj yeem tuaj yeem kaw cov li qub, ua rau hluav taws rau kis. Xaiv tus nqi xaiv: Ua kom muaj kev txiav txim siab ua raws li kev tswj hwm kev tswj hwm (phau ntawv / hluav taws xob), kev teb ceev, thiab pob nyiaj siv.


Cuab 5: Kev lag luam ntawv pov thawj 'uas ploj lawm', zoo tsis tuaj yeem lav

Rooj vag Li QubYuav tsum muaj ntawv pov thawj raws li cov qauv xws li API 6D thiab GB / T 12234, tab sis qee cov ntsiab lus me me kuaj xyuas cov kauj ruam tseem ceeb rau kev thauj khoom ceev. Piv txwv, rooj vag li qub uas tsis tau dhau los-kub cuam tshuam kev sim yog nquag mus rau brittle backstre hauv ib puag ncig ntawm -20 ℃; Lub rooj vag valve uas tsis dhau lub ntsev tshuaj txau ntxau cog hniav tom qab 3 lub hlis hauv ib puag ncig marine. Xaiv tus nqi xaiv: Cov chaw tsim khoom yog yuav tsum tau muab cov ntawv pov thawj ntawv pov thawj thiab cov ntaub ntawv tseem ceeb xws li qhov ntsuas kub, thiab corrosion tsis kam nyob hauv daim ntawv tshaj tawm kev ntsuam xyuas.


Xaus: Rooj vag Valve xaiv tsis yog qhov kev ua si yooj yim ntawm "parameter txuam", tab sis kev txiav txim siab, kev ua haujlwm, thiab ntawv pov thawj. Ib qho kev xaiv tseeb tuaj yeem txuas ntxiv cov kev pabcuam lub neej ntawm rooj vag qub los ntawm 3-5 zaug thiab txo cov nqi tswj los ntawm ntau dua 50%. Nco ntsoov: Nug "Puas tsim nyog rau kuv cov haujlwm ua haujlwm?" Thaum xaiv tau zoo dua li rov qab nws kaum zaus tom qab!
