This document discusses a hydraulic intensifier, which is a device that uses low pressure liquid to produce high pressure liquid. It has fixed and sliding cylinders or rams, as well as valves. There are two types: single acting intensifiers, which supply high pressure liquid during the downward stroke only, and double acting intensifiers, which provide continuous high pressure liquid supply. Hydraulic intensifiers are used between pumps and hydraulic machines like presses that require fluid at high pressure that pumps cannot provide. They are commonly used for clamping, holding, punching, presses, jacks, and torque wrenches. The document provides formulas to calculate the pressure and discharge rates of the high and low pressure liquids based on their areas and diameters

PROF . D . SINGHAL

2. WHAT IS IT??
 It is a device used for producing high
pressure liquid by using the energy of
larger amount of liquid at low pressure.
Low
pressure
liquid
to
High
pressure
liquid

3. COMPONENTS USED:
 FIXED RAM .
 SLIDING CYLINDER OR RAM.
 FIXED CYLINDER .
 VALVES.

4. HYDRAULIC INTENSIFIER:

5. TYPES OF INTENSIFIERS:
 Single acting intensifier: as it supplies
high pressure liquid during downward
stroke only.
 Double acting intensifier: it gives
continuous supply of high pressure
liquid.

6. DOUBLE ACTING INTENSIFIER

7. APPLICATION OF MACHINES:
 It is required in hydraulic machines such as
hydraulic presses which requires fluid at high
pressure. And the pump cannot provide high
pressure fluid therefore
a hydraulic intensifier is
placed in between the
pump and machine which
would supply high
p r e s s u r e fluid.

8. OTHER APPLICATIONS:
 Air operated hydraulic intensifier are
used commonly for clamping ,holding,
punching ,presses , jacks , torque
wrenches and m o r e.

9. CALCULATION :
 P2=P1(A1/A2)=P1(D1/ D2)^2.
where,
D1= ext. Diameter of sliding cylinder.
D2= diameter of fixed ram.
A1= cross sectional area of sliding cylinder.
A2= cross sectional area of fixed ram.
P1= intensity of pressure of low pressure
liquid.
P2= intensity of pressure of high pressure
liquid.

10. CALCULATION :(cont..)
 Q2= Q1(A2/A1) = Q1(D2/D1)^2.
where,
L= stroke length.
A1L= volume of low pressure liquid.
A2L= volume of high pressure liquid.
Q1= rate of discharge of low pressure
liquid.
Q2= rate of discharge of high pressure
liquid.
