How to Choose Hydraulic Pump and Hydraulic Cylinder?

How is a hydraulic system calculation done? When designing a Hydraulic System, firstly the dimensions of the movement elements (cylinder or hydraulic motor) are determined, and then the size of the power unit (pump, motor, valve, hydraulic tank, etc.) that will provide the prescribed pressure and speeds are determined.

HYDRAULIC PUMP AND HYDRAULIC CYLINDER SELECTION

Piston Section Area:

A1 = π x D² / 4

Piston Kolu Bölüm Alanı:

A2 = π x (D²-d²) / 4

Strok Hızı:

V = h / t

Kuvvet:

F = p x A

Gerekli Debi:

Q = A x V x 3 / 50

Tahrik Gücü:

P = p x Q / (600 x ų )

F = Kuvvet (daN)

p = Çalışma Basıncı (Bar)

A = Etkili Alan (cm²)

D = Piston Çapı (cm)

d = Piston Kolu Çapı (cm)

V = Piston Hızı (cm/sn)

h = Strok (cm)

t = Strok Süresi (sn)

Q = Verdi (Debi) (lt/dk)

P = Tahrik Gücü (kW)

ų .= Verim (0,8……..0,85)

Example Hydraulic System Calculation How is it done?

It is desired to be conveyed to the pressure casting machine by means of a liquid aluminum gutter assembly in a hot holding furnace. For this, a bucket device is required as seen in the location plan. Let's make a list of the circuit elements that will perform the movement, and how are the calculations required to dimension the hydraulic circuit elements?
