Question 1

Spana ya torque ya haidroliki hufanya kazi vipi?

Accepted Answer

A hydraulic torque wrench uses pressurized hydraulic fluid to push a piston, which drives a ratchet mechanism through a lever arm. The output torque is T = P × A × r, where P is hydraulic pressure, A is piston area, and r is the effective arm length.

Question 2

Ninawezaje kubadilisha shinikizo la bar kuwa torque?

Accepted Answer

T (N·m) = P (bar) × 0.1 (to MPa) × A (mm²) × r (mm) / 1000. The conversion factor 0.1 converts bar to MPa (N/mm²). The /1000 converts N·mm to N·m.

Question 3

Usahihi wa spana za torque za haidroliki ni upi?

Accepted Answer

Hydraulic torque wrenches typically achieve ±3% accuracy when properly calibrated, which is significantly better than manual torque wrenches (±10-25%). This makes them preferred for critical bolted joints.

Question 4

Spana za haidroliki hufanya kazi katika safu gani ya shinikizo?

Accepted Answer

Spana nyingi za torque za haidroliki hufanya kazi kwa shinikizo la 350–700 bar (5,000–10,000 psi). Spana za aina ya wasifu-chini (kaseti) kawaida hutumia kiwango cha juu cha 700 bar. Aina za gari-mraba zinaweza kufanya kazi kwa shinikizo la chini na pistoni kubwa zaidi.

Question 5

Ni lini ninapaswa kutumia spana ya haidroliki badala ya spana ya torque ya mkono?

Accepted Answer

Tumia spana za haidroliki kwa: (1) bolti M24 na zaidi ambapo torque ya mkono haifai, (2) viungo muhimu vinavyohitaji usahihi wa ±3%, (3) bolti nyingi zinazohitaji torque sawa, (4) nafasi ndogo (aina ya wasifu-chini), (5) matumizi ya flange yenye torque ya juu.
