Tiansu (Tianjin) Valve Group Co., Ltd. Yog tias koj yuav mus yuav cov lag luam wholesale customized y strainer hauv Suav teb, txais tos kom tau txais cov lus hais los ntawm peb lub hoobkas. Cov khoom zoo thiab tus nqi tsim nyog muaj.

Cov kua dej nkag mus rau hauv y hom strainer vaj tse los ntawm qhov nkag thiab ntws raws Y- zoo li txoj kab mus rau qhov screen. Vim qhov tsim, qhov nruab nrab yuav tsum dhau los ntawm qhov screen kom ncav cuag cov kav dej hauv qab. Lub vijtsam mesh tso cai rau cov kua dej kom dhau, cuam tshuam cov khoom thiab cov impurities ntawm sab hauv (ua "filter ncuav mog qab zib"). Cov khib nyiab cuam tshuam los ntawm lub ntiajteb txawj nqus ntawm lub tsev nyob hauv qab (qhov qis tshaj ntawm Y- txoj kev), tiv thaiv kev tshuaj ntsuam clogging. Thaum lub siab sib txawv ntawm qhov screen nce mus txog tus nqi preset (feem ntau yog 0.05-0.1 MPa) lossis thaum lub sijhawm tu, qhib lub tshuab nqus tsev kom tso cov khib nyiab pov tseg nrog qee qhov nruab nrab. Yog tias muaj teeb meem loj heev, kaw cov qhov hluav taws xob sab sauv / qis qis, tshem lub hau kawg (lossis tshem tawm cov khoom sib dhos), ntxuav lub vijtsam, thiab rov ua kom rov ua haujlwm. Cov txheej txheem no muaj feem xyuam rau ntau qhov ntau thiab tsawg, suav nrog qhov loj 10 nti y strainer siv hauv cov kav dej loj. Lub Y-zoo li tus tsim txo qis kev khiav hauj lwm (piv rau cov pob tawb strainers) thiab tso cai rau cov khib nyiab pov tseg kom zoo dua. Compact me me tso cai rau kab rov tav lossis ntsug kev teeb tsa (qhov chaw nres nkoj rau ntsug; nqes lossis sab rau kab rov tav).

Txoj Cai Ua Haujlwm

Lub y hom lim yog ib qho tseem ceeb ntawm cov khoom siv lim dej hauv cov kav dej xa dej.

Nws nta ib qho kev tsim kho siab heev, tsis muaj kev tiv thaiv, thiab yooj yim tawg.

Nws feem ntau yog ntsia rau ntawm qhov nkag ntawm lub siab txo cov li qub, nyem li qub, kaw- tawm li qub (piv txwv li, ntawm cov cua sov inlets), lossis lwm yam khoom siv los tshem tawm impurities thiab tiv thaiv li qub / khoom siv. Qhov kev tiv thaiv no tseem ceeb heev rau cov tshuab siv loj - cov lim lim zoo li 8 nti y lim.

Cov khoom tseem ceeb muaj xws li kev sib txuas, lub cev, lub vijtsam, flanges, kawg npog, thiab fasteners. Cov kua dej nkag mus rau hauv lub cev ntws mus rau hauv lub pob tawb, qhov twg cov khoom khib nyiab, thiab cov kua dej huv huv. Lub pob tawb cylindrical tsim kom muaj zog. Qhov kawg npog ntawm Y-kev sib tshuam tuaj yeem raug tshem tawm kom tshem tawm cov khib nyiab pov tseg ib ntus.

Khoom siv

Cov y hom lim yog ib qho tseem ceeb ua ntej - lim hauv cov kav xa dej, muaj npe rau nws sab hauv "Y"- zoo li txoj hauv kev. Nws feem ntau cuam tshuam cov khoom thiab impurities (xws li, xuab zeb, vuam slag, xeb) los tiv thaiv downstream li qub, twj, twj, thiab lwm yam, los ntawm hnav, jamming, los yog clogging. Siv dav hauv ntau lub tshuab thauj khoom (dej, roj, roj), nws ua haujlwm ua "thawj kab ntawm kev tiv thaiv" kom muaj kev nyab xeeb thiab ruaj khov ua haujlwm. Nws daim ntawv thov ntsuas los ntawm cov qauv kab mus rau cov uas xav tau kev muaj peev xwm txaus, xws li cov neeg ua haujlwm 10 nti y lim.

Kev tu, kev teeb tsa, thiab kev ua haujlwm ceev faj

I. Kev Tshawb Fawb Txhua Hnub (Txhua Hnub / Lub Limtiam, Kho raws li cov xwm txheej)

Visual & Leak Check

Saib xyuas vaj tse, kev sib txuas, lub tshuab nqus tsev rau cov xau, corrosion, deformation.

Siab poob & Flow Monitoring

Sau qhov sib txawv ntawm qhov sib txawv ntawm qhov screen. Teem caij cua tshuab yog nce txog 0.05 MPa. Rau cov chav loj loj xws li 10 nti y strainer, kev saib xyuas kev poob siab yog qhov tseem ceeb los tiv thaiv kev txwv tsis pub txaus.

Blowdown Valve Check

Ua haujlwm lub tshuab nqus tsev 1-2 zaug kom ntseeg tau tias kev ua haujlwm du, tsis nplaum.

II. Kev Saib Xyuas Sijhawm Sijhawm (Lub hli / Peb Hlis / Ib xyoos, Raws li Kev Siv Ua Haujlwm)

Kev Kho Vaj Tse	Cov ntsiab lus tu	Ntsiab Lus
Txhua hli	Kev ntxuav lub vijtsam (Online): Qhib lub tshuab nqus tsev, rov qab tshuaj ntsuam nrog qhov nruab nrab (rau qis- cov khoom khib nyiab).	Backflush rau 1-2 feeb nrog valve qhib. Xyuas kom cov khib nyiab saum npoo yog dej ntws. Kaw lub valve thiab xyuas seb lub siab poob rov qab los.
Peb lub hlis twg	Kev tshem tawm thiab ntxuav (Offline): Kaw qhov kev sib cais tawm, tso tsev nyob, tshem tawm qhov kawg npog / kav dej kom tshem tawm qhov screen.	1. Ntxuav lub vijtsam nrog siab - dej siab los yog cov kuab tshuaj uas tsim nyog (xws li, diesel rau roj). 2. Txheeb xyuas qhov kev puas tsuaj, deformation, txhaws. Hloov nrog tib spec yog puas. 3. Ntxuav vaj tse sab hauv, tshem tawm cov khib nyiab.
Ib nrab-Txhua xyoo	Kev Kho Hniav: Tshawb xyuas cov ntsaws ruaj ruaj (gaskets / O-rings) ntawm qhov kawg npog thiab kev sib txuas rau kev laus, kev puas tsuaj, corrosion.	Hloov cov ntsaws ruaj ruaj nrog tib cov khoom / spec yog tias tawv, tawg, los yog to. Xyuas kom cov sealing nto huv si thaum lub sij hawm installation.
Txhua xyoo	Kev Tshuaj Xyuas Kom Zoo: Txheeb xyuas cov phab ntsa thickness (tshwj xeeb tshaj yog nyob rau hauv corrosion), hnav ntawm threads / flange lub ntsej muag, blowdown valve tu.	1. Hloov cov lim dej yog tias phab ntsa thickness qis dua tus qauv (piv txwv li, Ntau dua lossis sib npaug li 1 hli hnav rau carbon steel). 2. Polish rusty threads / flange ntsej muag; hloov qhov txuas yog tias hnav hnyav heev. 3. Dismantle blowdown valve, ntxuav cov khib nyiab sab hauv, tshuaj xyuas valve foob kev ua haujlwm.

III. Cov kev cai ua haujlwm yooj yim

A. Blowdown Operation Standard

Teem caij Blowdown

Txhua lub lim tiam 1-2 zaug rau ib txwm muaj; txhua hnub rau cov dej khib nyiab siab (piv txwv li, cov dej khib nyiab hauv nroog, cov dej khib nyiab tsuas); nce zaus rau viscous media (xws li, roj hnyav). Lub tshuab ntim rau qhov loj 10 nti y strainer yuav ntau dua.

Blowdown Cov kauj ruam

a. Maj mam qhib blowdown valve (kom tsis txhob cov yeeb nkab vibration los ntawm nruab nrab surge).

b. Khaws lub valve qhib 30 sec - 1 min (kho raws li cov khib nyiab), kom txog thaum cov khoom nruab nrab tawm tsis pom cov khoom tseem ceeb.

c. Maj mam kaw blowdown valve (tsis txhob ua haujlwm tam sim ntawd).

Siab -Top Triggered Blowdown

Thaum lub siab poob siab tshaj 0.05-0.1 MPa (saib ntawm cov ntsuas), ua lub tshuab nqus tsev lossis tshuaj ntsuam xyuas tam sim ntawd, tsis hais lub sijhawm twg, los tiv thaiv kev txo qis, kev siv hluav taws xob ntau ntxiv, lossis lub vijtsam tawg.

Saib xyuas Flow/Pressure

Sudden flow drop los yog siab nce yuav qhia tau tias qhov screen clogging; chaw nyob tam sim ntawd.

Corrosion/High -Tseem Saib Xyuas

Txhua lub limtiam kuaj xyuas cov vaj tsev corrosion/xws li. Rau siab temps, paub meej tias cov ntsaws ruaj ruaj tsis muaj hnub nyoog / deformed.

B. Kev Saib Xyuas Kev Ua Haujlwm Zoo

Common Faults thiab Solutions

Kev txhaum

Ua rau

Kev daws teeb meem

Screen Clogging (High ΔP)

1. Cov impurities ntau dhau, ua tsis tau raws sijhawm.

2. Screen mesh zoo heev.

3. Fibrous khib nyiab tangling ntawm qhov screen.

1. Ntxuav lub vijtsam offline; xav txog coarser mesh screen yog tias cov cai hauv qab tso cai.

2. Nruab ib co ntxhib ua ntej- lim los yog fiber ntau lim.

Kev sib txuas / Xaus Cover Leakage

1. Aged / puas cov ntsaws ruaj ruaj.

2. Xov / flanges tsis nruj los yog sealing nto qias neeg.

3. Hnav sealing nto.

1. Hloov cov ntsaws ruaj ruaj, huv si sealing nto.

2. Tighten bolts nyob rau hauv kab pheeb ces kaum cross qauv (re- qhwv sealant ntawm threads).

3. Polish / kho sealing nto; hloov ib feem yog hnav hnyav.

Screen Damage (Tsis cuam tshuam)

1. Cov khoom siv tshuaj ntsuam tsis raug (xws li tus qauv SS rau kev kub siab).

2. Kev puas tsuaj thaum lub sijhawm teeb tsa / tu.

3. Kev ua haujlwm siab dhau ua rau tawg.

1. Hloov nrog lub vijtsam haum rau cov xwm txheej (xws li, thickened SS rau kev kub siab).

2. Tuav lub vijtsam kom zoo thaum lub sijhawm tu / txhim kho.

3. Txheeb xyuas qhov system siab; xyuas kom nws tsis tshaj qhov ntsuas ntsuas, tshwj xeeb tshaj yog rau cov qauv loj xws li 8 nti y strainer.

Blowdown Valve Sticking

1. Cov khib nyiab nkag mus rau hauv lub valve tub ntxhais.

2. Hnub nyoog seals adhering.

3. Corrosion los ntawm kev tsis ua haujlwm.

1. Dismantle valve, ntxuav cov tub ntxhais cov khib nyiab.

2. Hloov cov ntsaws ruaj ruaj.

3. Siv tau los tiv thaiv-cov roj nplua nyeem; ua haujlwm valve ib ntus.
