Vim li cas thiaj xaiv EN 10305 ERW Tubes rau Telescopic Hydraulic Lub tog raj kheej?
Hydraulic telescopic cylinders xav tau cov raj nrog:
Zoo heev concentricity rau piston alignment
Smooth sab hauv qhov chaw kom txo tau kev sib txhuam thiab hnav
Tight dimensional tolerances los xyuas kom meej kev sib khi thiab kev ua haujlwm siab
Uniform phab ntsa thickness los lis dynamic siab cycles
Womic's EN 10305 ERW cov raj ua tau raws li cov qauv no nrog kev ua haujlwm zoo thiab kev tshuaj xyuas qib siab.

Dimensional Tolerances Raws li EN 10305
| Yam khoom | Kev xav tau | Kev piav qhia |
| Outer Diameter kam rau ua (OD) | ± 0.08 hli (D ≤ 30 hli) ± 0.15 hli (D> 30mm) | Nyob ntawm qhov loj me thiab qhov txias-draw. EN 10305-2 muaj qhov tseeb dua. |
| Phab ntsa Thickness kam rau ua (WT) | ± 10% (EN 10305-2) ± 15% (EN 10305-3) | Raws li nominal phab ntsa thickness. Cold draw tubes yog qhov tseeb dua. |
| Ovality | ≤ 50% ntawm OD kam rau ua | Ovality yuav tsum tsis pub tshaj ib nrab ntawm OD kam rau ua. |
| Kev ncaj | ≤ 0.3 hli rau 1000 hli | Qhov siab tshaj qhov sib txawv pub dhau lub raj ntev. |
| Nto Roughness (Ra) | Ra ≤ 4 μm (tus qauv) Ra ≤ 1.6 μm (ntawm kev thov) | Smooth sab hauv thiab sab nrauv, haum rau hydraulic systems. |
| Eccentricity | ≤ 10% (WT / OD) | Eccentricity cuam tshuam lub zog sib npaug hauv hydraulic systems. |
Cov kev tolerances meej no lav kev sib hloov, kev ua haujlwm tsis zoo, thiab kev pabcuam ntev dua hauv kev siv hydraulic.
