Cylinder Blind End Area (in square inches):

PI x (Cylinder Radius)2

Example: What is the area of a 6 diameter cylinder?

Diameter = 6
Radius is 1/2 of diameter = 3
Radius2 = 3 x 3 = 9

x (Cylinder Radius)2 = 3.14 x (3)2 = 3.14 x 9 = 28.26 square inches



Cylinder Rod End Area (in square inches):

Blind End Area - Rod Area

Example: What is the rod end area of a 6 diameter cylinder which has a 3 diameter rod?

Cylinder Blind End Area = 28.26 square inches
Rod Diameter = 3
Radius is 1/2 of rod diameter = 1.5
Radius2 = 1.5 x 1.5 ....etc

design calculation of hydraulic lift pdf

Abstract

The following paper describes the design as well as analysis of a hydraulic scissor lift. Conventionally a scissor lift or jack is used for lifting a vehicle to change a tire, to gain access to go to the underside of the vehicle, to lift the body to appreciable height, and many other applications Also such lifts can be used for various purposes like maintenance and many material handling operations. It can be of mechanical, pneumatic or hydraulic type. The design described in the paper is dev ....etc

Air Cylinders

Air cylinders resemble any other cylinder in steam engine or cylinder in hydraulic circuit. Air cylinders are called actuators or motors. Air Cylinder is a device, which converts pneumatic power in to respired Mechanical power by reducing the pressure of the compressed air to atmospheric pressure.

The advantage of air cylinder is that it cannot be over loaded. It simply stalls when the cylinder is over loaded.
The essential parts are of Air Cylinder

1. Cylinder tube
2. Piston
3. Piston rod
4. Air inlet
5. Air outlet

MAIN PURPOSE:

The hydraulic jack is a device, which is used to lift heavy loads by applying a lot of small force. It is based on the PASCAL LAW, which states that the pressure intensity is equally transmitted in all directions through a mass of liquid in res

ITS PRINCIPLE OF MAIN OPERATION:

The operating principle of a hydraulic jack can be explained with the aid of the figure, some different parts are considered as a plunger and piston, operating on two cylinders of different diameter, which are interconnected at the b ....etc

Hydraulic actuators: cylinders



Properties:

.The cylinders have to be good quality steel with close tolerances.
There have to be good sealing both at the piston rod and at the cylinder.

.With time dirt may come in and damage the surfaces. This has to be possibly reduced.
In this case, the leakage will increase all the time.

Calculation of cylinders

1 Stick-slip
2 Transition
3 Normal behaviour

Hydraulic cylinders should be possibly operated in the 3rd region for ....etc
