1. Khoom siv: Alloy Steel vs. Ordinary Pipe
High-cov thooj voos kheej kheej zooSiv siab -lub zog alloy steel hlab (27SiMn/40Cr) rau lub chim, thiab tawv chrome-plated piston pas nrig (HRC 55+). Lawv tiv taus corrosion, khawb, thiab deformation txawm nyob rau hauv hnyav loads.
Tsawg- lub tog raj kheej zooSiv cov kav hlau uas pheej yig los sis nyias nyias -cov phab ntsa uas tsis yog- cov kav dej txheem uas tsis muaj zog txaus. Piston rods muaj nyias, tsis muaj zog plating uas khawb thiab xeb sai sai.
2. Machining Precision: Daim iav tiav vs. Rough Surface
High-cov thooj voos kheej kheej zooSab hauv bore yog precision-honed rauRa Tsawg dua lossis sib npaug li 0.4μm- smooth li daim iav. Qhov no minimizes seal hnav thiab sab hauv to.
Tsawg- lub tog raj kheej zooRough, tsis sib npaug sab hauv phab ntsa ua zoo li cov ntaub ntawv, txiav cov ntsaws ruaj ruaj thiab ua rau tsis ua hauj lwm ntxov.
3. Sealing System: Tus yuam sij rau Leak -Kev Ua Haujlwm Dawb
High-cov thooj voos kheej kheej zooNruab nrogsiab -siab resistant seals(700bar ntsuas) uas tiv taus qhov kub thiab txias, kev laus, thiab kev siv hnyav. Tsis muaj dej xau rau 3-5 xyoos.
Tsawg- lub tog raj kheej zooSiv cov roj hmab pheej yig uas ua kom tawv, tawg, thiab ua tsis tiav hauv lub hlis, ua rau cov roj ntws tawm, poob siab, thiab lub twj tso kua mis puas.
4. Tus Qauv Tsim: Kev Nyab Xeeb & Durability vs. Shortcuts
High-cov thooj voos kheej kheej zooTag nrho nruab nrog kev taw qhia rings, plua plav ntsaws ruaj ruaj, tsis siv neeg kaw lus, thiab xauv ceev. Resistant sab loads, tiv thaiv overload, thiab tswj lub siab ruaj ntseg rau ntev tuav.
Tsawg- lub tog raj kheej zooTshem tawm cov buffers, nyias tawm cov lus qhia cov khoom, thiab hla kev tiv thaiv plua plav. Yooj yim rau lub tog raj kheej cov qhab nia, khoov, thiab cia li poob siab.
5. Cov Qauv Ntsuas: Cov Ntawv Pov Thawj Zoo vs. Tsis Muaj Kev Nyab Xeeb Kev Nyab Xeeb
High-cov thooj voos kheej kheej zooDhau tag nrho lub Hoobkas kuaj:700bar kev ntsuas siab, ntsuas ntsuas siab, ntsuas kev qaug zog, thiab tshuaj xyuas ultrasonic. suav nrog cov ntawv pov thawj raug cai.
Tsawg- lub tog raj kheej zooTsuas yog kuaj rau qhov yooj yim to; tsis ntev - lub sij hawm durability pov thawj. Kev tsis ua haujlwm feem ntau tshwm sim hauv kev ua haujlwm tiag tiag.
Kev sib piv kev ua haujlwm: Cov ntaub ntawv qhia qhov sib txawv
| Yam khoom | High -Lub tog raj kheej zoo | Tsawg-Lub tog raj kheej zoo |
|---|---|---|
| Kev Pabcuam Lub Neej | 5,000-10,000 teev | 1,000–3,000 teev |
| Seal Lub Neej | 3-5 xyoos | 3–6 lub hlis |
| Internal Leakage | Tsawg heev, ruaj khov | Siab, yooj yim poob siab |
| Failure Rate | <2 times/year | Ntau dua lossis sib npaug li 1 zaug / hli |
| Tus nqi kho mob | Tsawg, niaj hnub saib xyuas nkaus xwb | Siab, nquag kho |
Vim li cas pheej yig lub tog raj kheej ua tau raug nqi ntau dua
Tsawg- cov thooj voos kheej kheej txuag nyiaj ua ntej tab sis nqa cov nuj nqis zais:
Kev poob qis: Ntau lawm nres, ua rau qeeb thiab kev nplua.
Kho cov nqi: Nquag hloov lub foob, hloov roj, thiab tshuab disassembly.
Kev nyab xeeb: Lub tog raj kheej tawg, poob tam sim ntawd, thiab overturns ua rau raug mob thiab khoom puas tsuaj.
Tus nqi tag nrho: High- zoo lub tog raj kheej kav 5 xyoo; pheej yig yuav tsum tau hloov txhua xyoo. Tus nqi tag nrho yog2-3 npaug siab dua.
Yuav Xaiv Li Cas: Kev Ntsuam Xyuas Ceev Kom Zoo
Ua kom tiav: Ntxuav welds, txawm txheej, tsis muaj burrs lossis xeb.
Cheebtsam: Pom pom plua plav seals, coj lub nplhaib, thiab cov qauv tsis sib xws.
Specs: Clear rated siab, stroke, bore, thiab khoom - tsis overstated tonnage.
Warranty: Cov ntaub ntawv pov thawj thiab cov ntawv xeem los ntawm cov chaw tsim khoom.
Kev pom kev lag luam
Hydraulic cylinders yog precision siab - cov khoom siv siab, tsis yog "hlau raj." Ntev -kev sib tw lub sij hawm cia siab raucov ntaub ntawv muaj zog, kev ua haujlwm zoo, kev sim nruj, thiab daim ntawv thov - kho kom haum. Kev ua tau zoo txo tus nqi tiag tiag thiab ua kom muaj kev nyab xeeb.
