Case Analysis: Nquag Hydraulic Hose Bursts? Txoj kev xaiv thiab kev tiv thaiv yog qhov tseem ceeb!
Dec 15, 2025| Case Analysis: Nquag Hydraulic Hose Bursts? Txoj kev xaiv thiab kev tiv thaiv yog qhov tseem ceeb!
Raws li "cov hlab ntsha" ntawm hydraulic systems, hydraulic hoses tuaj yeem ua rau tsis yog cov khoom siv poob qis nkaus xwb tab sis kuj muaj kev nyab xeeb thaum lawv tawg. Tsis ntev los no ntau qhov xwm txheej ntawm hydraulic hose tsis ua haujlwm tau ua rau kev lag luam mloog. Niaj hnub no, peb yuav delve rau hauv qhov ua rau ntawm hose tawg thiab tiv thaiv kev ntsuas, qhia koj yuav ua li cas xaiv hydraulic hoses kom raug!
Tshooj I. Kev tshuaj xyuas tsib feem ntau ua rau Hydraulic Hose tawg:
Siab dhau:Thaum lub siab ua hauj lwm siab tshaj 80% ntawm lub hose qhov ntsuas lub peev xwm, qhov kev pheej hmoo ntawm bursting nce sharply.
Abnormal Oil Temperature:Kev ua haujlwm ntev tshaj li 70℃accelerates roj hmab laus, halving lub hose lifespan rau txhua txhua 10℃nce.
Pulse Fatigue:Kev hloov pauv ntau zaus ua rau qaug zog tawg hauv cov hlau braiding txheej (suav txog 43% ntawm qhov tshwm sim tawg).
Kev teeb tsa tsis raug:Kev nyuaj siab concentration tshwm sim los ntawm ntau dhau me me bending radii los yog twisted installation.
Cov dej tsis sib haum:Cov tshuaj tiv thaiv ntawm cov kua dej hydraulic thiab cov khoom siv hose ua rau o / tawv.
Ntu II. Xya txoj hauv kev los txuas ntxiv Hydraulic Hose Service Life:
Tso cai 3% -5% Slack thaum lub sijhawm teeb tsa:Tsis txhob sib zog ntau dhau vim thermal expansion thiab contraction.
Siv Dedicated Clamps rau Kho:Muab cov ntsiab lus txhawb nqa txhua 500mm.
Tsis tu ncua tshuaj xyuas "Peb Metrics":Deg hardness (Shore A), sab nraud txoj kab uas hla nthuav dav (tsawg dua lossis sib npaug li 10%), thiab qhov ntev hloov pauv (tsawg dua lossis sib npaug li ± 2%).
Tiv Thaiv Tiv Thaiv "Pulse Killer":Nruab cov accumulators hauv circuits nrog nquag pib-stop cycles.
Xaiv Hloov Fittings:45℃lossis 90℃lub luj tshib nce lifespan los ntawm 5 npaug piv rau cov khoov ntse.
Thov Kev Tiv Thaiv - Kev Kho Kev Sib Nrauj:Qhwv lub tes tsho ntawm kev sib cuag ntawm cov ntsiab lus (ua pov thawj kom txo tau hnav txog li 87%).
Tsim cov ntaub ntawv hloov pauv:Kev hloov pauv yuav tsum raug pom zoo tom qab 2000 teev ua haujlwm lossis 3 xyoos.
Ntu III. Kev Ceeb Toom Tshwj Xeeb: Ua tib zoo saib xyuas cov nam no thaum xaiv cov hoses:
(1) Kev ntsuas kev ntsuas siab:
Ua Haujlwm Siab Tsawg dua lossis sib npaug li 80% ntawm Rated Pressure
Pulse Pressure Tsawg dua lossis sib npaug li 67% ntawm Rated Pressure
Kev Rated Siab Ntau dua lossis sib npaug li 4 npaug ntawm Rated Pressure
Cov ntaub ntawv ntsuas kev lag luam: Hoses ua raws li SAE 100R13 tus qauv pom 3 zaug lub neej ntev dua hauv kev ntsuas pulse piv rau cov qauv hoses.
(2) Kub Adaptability:
Standard Hoses: -40℃rau +100 degree
Siab -Tsub Hoses: -50℃rau +150℃(nrog rau txheej tshwj xeeb fluorocarbon roj hmab)
Ultra-Cov Hoses Kub Kub: -70℃rau +80 degree
(3) Kev xaiv hom qauv:
| Hom | Ua Haujlwm Siab | Yam ntxwv | Tej kev siv |
|---|---|---|---|
| 1- Hlau Braid | 21 MPa | Zoo Flexibility | Tsawg- cov khoom siv txawb siab |
| 2- Hlau Braid | 35 MPa | Zoo heev Balance | Main systems ntawm kev tsim kho machinery |
| 4- Kauv Hlau | 70 MPa | Siab Pulse Resistance | Hydraulic presses, txhaj tshuaj molding tshuab |
(4) Cov Ntawv Pov Thawj Tseem Ceeb:
✔ SAE J517 Certification
✔ EN853 Txuj
✔ SAE100R*AT (eg, R13, R15)
✔ MSHA Certification (Qhov tseem ceeb rau cov khoom siv mining)
