Shin kuna mamakin yawan ƙarfin da injin silinda ke bayarwa da gaske? Makullin yana cikin tsari mai sauƙi.
Mahimman tsari don silinda na hydraulic tilasta lissafin[^4] shine F = P × A[^1], inda F ke wakiltar ƙarfin da aka samar, P shine matsi na hydraulic da ake amfani dashi, kuma A shine ingantaccen wurin aiki na piston. This formula helps determine the cylinder's pushing or pulling capability based on the system's pressure and the cylinder's physical dimensions. Yin amfani da wannan daidai yana tabbatar da cewa silinda yana da isasshen iko don aikinsa.

Wannan shi ne ainihin dabara.
- F: Karfi (yawanci a cikin fam ko Newtons).

Misali 1: Dauke Abu Mai nauyi
Ka yi tunanin dagawa a 10,000 lb abu.
- Ƙarfin da ake so (F): 10,000 lbs.
- Akwai Matsi na Tsarin (P): 2,000 PSI.
- Wurin Piston da ake buƙata (A): F / P = 10,000 lbs / 2,000 PSI = 5 sq inci.
- Diamita na Bore da ake buƙata: Square tushen (4 × A / p) = Tushen murabba'i (4 × 5 / 3.14159) ≈ 2.52 inci.
Don haka, ana buƙatar silinda mai aƙalla diamita 2.52-inch.
Misali 2: Excavator Arm Movement
Yi la'akari da hannun mai tona wanda ke buƙatar yin aiki 20 ton na karfi.
- Ƙarfin da ake so (F): 20 ton = 40,000 lbs.
- Silinda Bore Diamita: 6 inci.
- Yankin Piston (A): (p × (6 inci)²) / 4 ≈ 28.27 sq inci.
- Matsin da ake buƙata (P): F / A = 40,000 lbs / 28.27 sq inci ≈ 1,415 PSI.
Dole ne tsarin na'ura mai aiki da karfin ruwa ya iya bayarwa a kalla 1,415 PSI don cimma wannan karfi.
Misali 3: Dannawa tare da Takamaiman Tonnage
Ana buƙatar latsawa a yi amfani 50 awo ton na ƙarfi.
- Ƙarfin da ake so (F): 50,000 kg ≈ 110,231 lbs.
- Matsin tsarin (P): 3,000 PSI.
- Wurin Piston da ake buƙata (A): 110,231 lbs / 3,000 PSI ≈ 36.74 sq inci.
- Diamita na Bore da ake buƙata: Square tushen (4 × 36.74 / p) ≈ 6.84 inci.
