It is a device used for producing high pressure liquid by using the energy of larger amount of liquid at low pressure.

COMPONENTS USED:

FUNCTION: It is used to increase the intensity of pressure of liquid by energy available from a large quantity of water at a low pressure.

CONSTRUCTION: It consist of fixed ram surrounded by a sliding cylinder which is itself surrounded by a larger fixed cylinder as show in figure.

The sliding cylinder contains water at high pressure which is supplied to the machine through fixed ram. The large fixed cylinder contains water from the main supply at a low pressure.

HYDRAULIC INTENSIFIER:

HYDRAULIC INTENSIFIER:

WORKING : A large quantity of water at a low pressure from a supply enters the large fixed cylinder through a valve D. same time, the sliding cylinder lies at a bottom of the stroke.

The valve D and B are than closed and valve A is opened. hence low pressure liquid from supply enters the sliding cylinder through valve A ,and valve C is opened which allows the low pressure liquid from fixed large cylinder to discharge to exhaust.

HYDRAULIC INTENSIFIER:

Therefore, sliding cylinder moves upward. When sliding cylinder reaches its topmost

position, the inside space of sliding cylinder is full of low pressure liquid. Then valve A and C are closed and valve B and D are opened.

The low pressure liquid from supply the enters large fixed cylinder and forces the sliding cylinder to move downward, hence pressure of liquid inside the sliding cylinder is increased and high pressure liquid is supplied to the hydraulic machine.

Let,P1= intensity of pressure of low pressure liquid.P2= intensity of pressure of high pressure liquid.A1= cross sectional area of sliding cylinder=.A2= cross sectional area of fixed ram=.D1= Outer Diameter of sliding cylinder.D2= Outer Diameter of fixed ram.

CALCULATION :

Force exerted by low pressure liquid on the sliding cylinder (in downward direction)=Force exerted by high pressure liquid on the sliding cylinder(in upward direction) Equating the upward and downward forces

Intensity of high pressure liquid 2

CALCULATION :

Air operated hydraulic intensifier are used commonly for clamping, holding, punching ,presses, jack, torque wrenches and more.

It is used in hydraulic press, crane, and lift which require liquid at very high pressure.

The high pressure can not be obtain from main supply directly. It is located between pump and the hydraulic machine.
