HYDRAULIC SIAB SOJ KEV PAB CUAM HLUB STALAL AV tshwm sim tshwm sim?

Koj puas xav tau aHYDRAULIC SIAB TSIM ROGAL VALVE? Kev tiv thaiv kev nyab xeeb tseem ceeb

Muaj cov khoom siv ua tsis tiav cov kev puas tsuaj uas tsis muaj qhov tsim nyog tswj tau. Cov lus qhia no tsis sib xwsHYDRAULIC SIAB TSIM ROGAL VALVEMechanics, lus ceeb toom, thiab xaiv cov qauv - nrog cov ntaub ntawv los ntawm cov ntaub ntawv hauv cov ntaub ntawv hauv cov cav ntoo.

Cov tub ntxhais muaj nuj nqi: Ntau tshaj li tsuas yog muaj kev nyab xeeb

1. Kev tswj siab siab hauv qab thauj khoom

TxhuaSiab Saws Lub Hwj Huam Husal System pab peb lub hom phiaj:

• Lub zog thaum muaj xwm ceev(Tiv thaiv hose tawg)
• Nruam Kev Tswj Xyuas(Hloov kho rau cov tso kua mis surges)
• Thermal Kev Txhim Kho(them nyiaj rau cov cua sov)
• Kev Ua Haujlwm Ntau:

(ASME B31.3 cov qauv yuav tsum tau kev pab tsis pub dhau 10% ntawm teeb tsa siab)

Cov Ntsiab Lus Mob Mob: Thaum Pab Tau Cov Kho Mob Li Cas

2. Cov neeg tua neeg nyob hauv cov tshuab hydraulic

Cov tsos mob no xav tau tam sim ntawdKev Ntsuas HYDRAULIC nyem Kev Soj Ntsuam:

KUB KHEEJ KHEEJ COJ

• Stuck valve disc txwv
• Causes: Contamination (ISO 4406 >18/15/12) lossis lub caij nplooj ntoo hlav nkees

Fluid Overheating (>180℃f)

• Nruam Tawv Bypassing Cov Khaub Ncaws Dej Temps
• Cov Ntsiab Lus: 7% Viscosity Poob Ib 18 Degree F → Cov Khoom Zoo

Horner rauj nrov nrov

• Ceev ceev valve cycling kev puas ntsoog yeeb nkab
• Txhim kho: install accessorator lossis kho cov nrawm nrawm

3. Kev lag luam -} tsis muaj nuj nqis

• Kev ua teb: $ 8k avg. Realalterter twj tso kua mis hloov
• Kev tsim khoom: 22 hrs downtime per todg valve txhaum
• Kev tsa tsev: OSHA nplua txog $ 15K rau cov khoom txiav

Kev sib sib zog nqus dej: Valve hom lus

4. Xaiv koj lub siab nyem Valve

Direct - Ua Nqaij Li Qub

Proge Pros: Cov lus teb ceev (<25 ms), compact size
Cons: Txwv rau 3000 psi, nquag mus rau chatter

Pilot -} Cov Qub

▸ Pros: Cov 10,000+} psi, kho tswj
Cons: 3x tus nqi, yuav tsum muaj ultra -} cov kua huv si

Thermal Pab Tsa Li Qub

Cov kev siv tshwj xeeb: Tiv thaiv cov tshuab sib khi los ntawm cov hnub ci kub hnub ci

Cov kws tshaj lij: ntxiv ib qho 0.1-thib ob qeeb module thaum siv cov twj tso kua tsis yooj yim.

Txheeb xyuas daim ntawv txheeb (tiv thaiv 92% ntawm kev ua tiav)

5. Xoom {- downtime soj ntsuam raws tu qauv

1.Weekly:

• Kos rau sab nraud xau (1 poob / min= tsis ua tiav)
• Saib xyuas cov khoom siab ntawm cov ntaub ntawv Logger

2.Qhov:

• Kuaj teeb tsa siab nrog cov tes dag zog tuag
• Flush Valve Lub Rooj nrog hlp 46 kua

3.Nim siab:

• Replace spring if >5% ntev txo
• Ultrasonic tshev rau kev yaig sab hauv
