INTRODUCTION
Hydraulic power packs can be defined as self-contained power units or stand-alone devices which are
used in hydraulic machinery. It doesn’t contains a built in power supply and it is used to transmit
power from one place to another. In order to run a machine the whole system uses enclosed fluid to
transfer to transfer power from one source to another. The man behind the rise of hydraulic system
was Laissez Pascal. According to Pascal’s law, whenever there is an increase in the pressure at any
point in an enclosed liquid then there is an equal increase in each and every point of the container.
Hydraulic power packs are designed on the Pascal’s law. There are different shapes and size of
hydraulic power packs available in the market. Some of them are very large and stationary while
others are much smaller. It depends upon what is the requirement of the user. Some of them can be
easily transported via a car or van also.

Fig: Hydraulic Power Pack
It uses a control valve to deliver power and then this power is used to run the machinery connected to
it. All hydraulic power packs comes with different types of valve connections which can be used to
connect variety of machines depending upon the requirements.
In order to run hydraulic power packs for a long time it requires regular and timely maintenance. Then
only a safe operation is guaranteed. There may be large amount of issue that may a
ive over the
time such as cracks or dents in the tubes, co
osion in the reservoir or change of liquid. So, the user
must keep these points in mind before and after the use of power packs. These power packs are used
in various applications such as car lifts, sanitation trucks etc.
COMPONENTS
Below pictures shows the different components involved in the making of hydraulic power packs:
Below are the functions of different components involved in the hydraulic power packs:
1. Reservoir
It contains the enclosed oil. The storage volume of the tank is enough for the oil. This
eservoir ensures that the oil inside is kept under good condition. There are different sizes of
eservoirs available in the market...
