Cov yam ntxwv tseem ceeb

Integrated Modular Design

Ua kelub cev muaj zog, iav twj tso kua mis, roj tank, solenoid valve thaiv, nyem valve, lim, thiab ntsuas ntsuasnyob rau hauv ib chav tsev, tshem tawm cov kav dej sab nraud thiab txo qhov kev pheej hmoo ntawm kev xau.

Lub solenoid valve thaiv integrates directional tswj li qub, check li qub, thiab throttle li qub, enabling meej tswj cov roj ntws kev taw qhia thiab ceev rau kev cob cog rua actuators (xws li, nres lub tog raj kheej, rail clamp lub puab tsaig).

Ntau-Kev Tiv Thaiv Kev Nyab Xeeb Qib

Overpressure nyem valve: Tsis siv neeg tshem tawm thaum lub siab tshaj 22 MPa (10% siab tshaj qhov ntsuas siab) los tiv thaiv lub twj tso kua mis thiab cov kav dej los ntawm kev puas tsuaj.

Roj theem sensor: Ua kom lub tswb nrov thaum cov roj qib poob qis dua MIN cim, tiv thaiv twj cavitation.

Roj kub sensor: Kaw lub cev muaj zog yog tias cov roj kub siab tshaj 65 degree, tsis txhob muaj roj deterioration thiab foob kev laus.

High -Efficiency Filtration System

Nruab nrog asuction lim (100 μm)thiabrov qab lim (25 μm)kom tshem tawm impurities los ntawm cov roj Circuit Court, ncua kev pab cuam lub neej ntawm li qub thiab twj tso kua mis.

Lub lim xa rov qab muaj qhov ntsuas qhov sib txawv ntawm qhov ntsuas siab -thaum qhov taw qhia tig liab, lub lim dej yuav tsum tau hloov tam sim ntawd.

Yooj Yim Kho & Txhim Kho

Transparent oil level gauge thiab drain plug rau ceev roj ntsuam xyuas thiab hloov roj.

Flange-mounted tsim rau kev teeb tsa ncaj qha rau ntawm cov khoom siv hauv tsev; roj qhov hluav taws xob / inlet ports siv cov txheej txheem threaded sib txuas kom yooj yim txuam nrog actuators.

Txoj Cai Ua Haujlwm

YZA20-8 series ua haujlwm ua ib qhotas mus li -pressure supply systemrau nres / rail clamp hydraulic actuators, nrog peb lub luag haujlwm tseem ceeb:

Siab Tsim -Up State (Tso Nres Nres / Rail Clamp)

Thaum cov khoom siv tswv tsev (piv txwv li, crane) xav tau pib, lub kaw lus tswj tau xa cov teeb liab los txhawb lub zog solenoid valve.

Lub cev muaj zog tsav lub iav twj tso kua mis los kos cov roj los ntawm lub tank, nias nws mus rau 20 MPa, thiab xa mus rau lub actuator (xws li, lub tog raj kheej nres). Hydraulic siab thawb lub piston kom tso tus nres / tsheb ciav hlau clamp.

Thaum lub siab ncav cuag tus nqi ntsuas, lub siab hloov pauv xa cov teeb liab kom nres lub cev muaj zog (lossis hloov mus rau siab- tuav hom) kom txuag tau lub zog.

Siab-Holding State (Kev Ua Haujlwm Khoom Siv)

Lub check valve nyob rau hauv lub solenoid valve thaiv tswj lub siab nyob rau hauv lub actuator Circuit Court, kom ntseeg tau tias lub nres / rail clamp tseem tso tawm thaum lub sij hawm cov khoom siv.

Yog tias lub siab poob qis vim yog me me, qhov hloov pauv siab ua rau lub cev muaj zog rov pib dua thiab rov ua kom lub zog ntxiv.

Unloading State (Braking / Clamping)

Thaum cov khoom siv tswv tsev nres, solenoid valve de{0}}energizes, thiab cov roj hluav taws xob txuas nrog lub tank.

Hydraulic roj nyob rau hauv lub actuator ntws rov qab mus rau lub tank nyob rau hauv qhov kev txiav txim ntawm lub nres lub disc caij nplooj ntoos hlav los yog rail clamp lub clamping caij nplooj ntoos hlav, thiab lub actuator rov qab mus cuag braking / clamping.

Cov Lus Qhia Txog Kev Kho Mob

1. Kev soj ntsuam txhua hnub (5–10 feeb / ua haujlwm)

Roj Qib & Kev Ntsuas Zoo: Paub meej tias qib roj nyob nruab nrab ntawm MAX thiab MIN cov cim; xyuas cov xim roj (ntshiab amber yog li qub-cov roj tsaus/turbid qhia tias muaj kab mob thiab yuav tsum tau hloov).

Kev Ruaj Ntseg & Kev Tshawb Fawb: Saib xyuas qhov ntsuas siab-siab yuav tsum nyob ruaj khov ntawm 20 MPa thaum lub sijhawm ua haujlwm; tshuaj xyuas tag nrho cov yeeb nkab sib txuas, valve thaiv qhov cuam tshuam, thiab cov roj ntsaws ruaj ruaj rau cov roj drips (tighten xoob pob qij txha tam sim ntawd).

Hluav taws xob System Check: Tshawb xyuas cov kab hluav taws xob lub cev, cov kab hluav taws xob solenoid valve, thiab kev sib txuas ntawm cov sensor rau fraying lossis loosening; txheeb xyuas cov roj theem / roj temp tswb ua haujlwm ib txwm.

Filter Indicator Check: Xyuas kom meej qhov ntsuas rov qab lim yog ntsuab (liab=thaiv cov lim dej, xav tau hloov).

2. Lub Sijhawm Saib Xyuas Txhua Lub Sijhawm

Kev Kho Vaj Tse	Cov haujlwm tseem ceeb	Paub meej & Standards
1 hli	Filter Cleaning & Fastener Tightening	- Ntxuav lub tshuab nqus tsev lim (tshem tawm thiab yaug nrog cov roj hydraulic huv si);- Re-Tighten mounting bolts thiab yeeb nkab sib txuas ceev (torque: 30–40 N·m rau M12 bolts).
3 Lub Hlis	Roj Hloov & Cov Txheej Txheem Ntshav	- Tshem cov roj qub, yaug lub tank nrog cov roj ISO VG46 huv si, thiab rov qab mus rau MAX cim;- Cua los ntawm qhov system: khiav lub tsev tsis muaj -load rau 5 feeb, ces voj voog lub solenoid valve 3-5 zaug kom tshem tawm cov cua (cua ua rau lub siab tsis ruaj).
6 hli	Filter Element & Seal Hloov	- Hloov cov khoom lim rov qab (25 μm);- Tshawb xyuas thiab hloov cov laus O- cov nplhaib thiab cov ntsaws ruaj ruaj hauv lub valve thaiv thiab cov yeeb nkab sib txuas kom tiv thaiv kom tsis txhob tawm.
12 Lub Hlis	Comprehensive Overhaul	- Disassemble lub iav twj tso kua mis thiab tshawb xyuas qhov hnav ntawm lub zog thiab cov kabmob (hloov yog tias qhov kev tshem tawm ntau tshaj 0.1 mm);- Calibrate lub nyem valve kom paub tseeb tias nws unloads ntawm 22 MPa;- Ntsuas cov roj qib / roj temp sensors thiab siab hloov kom raug; - Ntxuav lub tank sab hauv kom tshem tawm cov impurities.

3. Kev Kho Ib puag ncig tshwj xeeb

Siab -Dust/Coastal Environments: Nruab ib lub plua plav npog ntawm lub cev muaj zog thiab roj tank; siv cov tshuaj tiv thaiv- xeb roj rau chav tsev txhua hli; txo cov lim hloov mus rau 4 lub hlis.

Tsawg-Qhov kub thiab txias (-20℃txog 0 degree): Hloov ISO VG46 roj nrog qis -kub ISO VG32 roj; preheat chav tsev rau 10 feeb ua ntej ua haujlwm kom txo cov roj viscosity.

Kev Tiv Thaiv Kev Nyab Xeeb

Lockout-Tagout Ua ntej Kev Kho: Txiav tawm lub hwj chim thiab dai daim ntawv ceeb toom "Tsis Muaj Kev Ua Haujlwm"; tso tawm tag nrho cov siab nyob rau hauv lub system los ntawm qhib lub unloading valve ua ntej disassembling Cheebtsam.

Roj Compatibility: Siv tsuas yog ISO VG46 los tiv thaiv- coj cov roj hydraulic- sib xyaw hom lossis hom sib txawv yuav ua rau lub foob tawv thiab lub cev tsis ua haujlwm.

Overpressure txwv: Tsis txhob kho lub valve kom siab tshaj 22 MPa; qhov no yuav ua rau lub twj tso kua mis thiab cov kav dej puas.

Tswb teb: Nres lub tsev tam sim ntawd thaum lub tswb ntsuas roj / roj kub tshwm sim - tsis txhob ua haujlwm txuas ntxiv kom tsis txhob muaj lub twj tso kua mis burnout.
